Yerba Magic Review: Brainista's 5-in-1 Instant Yerba Mate With Lion's Mane, L-Theanine and Probiotics, What Each Ingredient Can Do

Our verdict

Worth it if you want a quick, flavoured, low-sugar caffeine drink as an alternative to coffee, and you treat the extras as a bonus. Yerba Magic gives 100 mg of caffeine from yerba mate with 100 mg of L-theanine, 1,000 mg of lion's mane and a prebiotic and probiotic blend, at 40 calories a scoop. The energy is real. The gut, metabolism, weight and skin promises are not shown for this product, and the refund policy excludes sale items. Yerba Magic scores 5.6 out of 10, held back by stretched wellness claims and price per serving.

The short version

• What it is: a flavoured instant yerba mate powder with lion's mane, L-theanine, prebiotics and probiotics.
• Price: $39.99 for 30 servings on the store listing on 5 October 2026, about $1.33 a serving.
• Best trait: coffee-strength caffeine with L-theanine in a quick, low-sugar drink.
• Biggest drawback: wellness claims beyond the evidence, and a refund policy that excludes sale items.
• Our score: 5.6 out of 10.

Pros & cons

The pros come from the caffeine and L-theanine combination, low sugar and convenience. The cons are about overreaching claims, modest evidence for the extras, price and return terms.

How it works

Yerba Magic is a powder you mix with water. Each 11 g scoop contains yerba mate extract providing 100 mg of caffeine, 1,000 mg of lion's mane mushroom, 100 mg of L-theanine, and a 2,000 mg fibre blend of chicory inulin, apple fibre, citrus pectin and pea fibre with 500 million CFU of probiotics, according to the label. It is sweetened with allulose and stevia, with 2 g of added sugar.

The caffeine provides the energy. L-theanine, an amino acid from tea, may smooth the jittery side of caffeine. Lion's mane is a mushroom marketed for focus. The fibres and probiotics are aimed at gut health. The maker says the combination supports energy, focus, digestion, metabolism, weight goals and skin. A very different daily supplement, a chitosan blend sold for weight management, is covered in our Sifts review.

1. 01

   Fill a cup with water

   Step 1: Add cold water and ice for an iced drink, or warm water if you prefer it hot.

2. 02

   Add one scoop

   Step 2: Stir in one 11 g scoop of Yerba Magic, about 30 servings per bag.

3. 03

   Mix and drink

   Step 3: Whisk or use a frother until dissolved. The maker suggests it as a morning coffee alternative or a midday energy drink.

Who makes it

Yerba Magic bags carry the Brainista name, and returns go to a Brainista email address. Brainista is known for mushroom coffee products. The page says it is produced in the USA with yerba mate from South America.

What the photos show

The page shows the purple and pink bags in three flavours, iced drinks, ingredient graphics, a supplement facts panel, a comparison chart and screenshots of social media videos. Several images are stylised graphics rather than photos of real use.

Yerba mate

Yerba mate is a South American holly whose leaves are brewed like tea. It contains caffeine and related compounds, and has a grassy, earthy taste. Instant extracts deliver the caffeine without brewing.

Sweeteners

The label lists allulose, cane sugar, natural flavours, citric acid and stevia among other ingredients. Allulose is a low-calorie sugar that does not count as added sugar on US labels, which helps keep the figure at 2 g. Some people find allulose and stevia cause mild stomach upset in large amounts.

Calories and carbohydrates

Each serving has 40 calories and 9 g of carbohydrate, with 2 g of fibre, according to the page. That is far lighter than a flavoured coffee shop drink or a sugary energy drink.

Why functional drinks are booming

Drinks combining caffeine with mushrooms, adaptogens and gut ingredients have become a fast-growing category, often marketed on social media. They promise more than energy. The evidence usually lags far behind the marketing.

How it compares with traditional mate

Traditional yerba mate is brewed from loose leaves in a gourd, often shared socially in Argentina, Uruguay and Paraguay. Yerba Magic uses an extract to deliver a measured caffeine dose in a sweetened, flavoured powder. It keeps the caffeine but not the ritual or the leaf's full flavour.

Caffeine and L-theanine

The 100 mg of caffeine matches a strong cup of coffee, according to the page. L-theanine in a 1:1 ratio with caffeine is a popular combination in energy products, with some small studies suggesting smoother focus.

Lion's mane

Lion's mane (Hericium erinaceus) is an edible mushroom studied for effects on nerve growth in the lab. Human evidence is limited. At 1,000 mg, the dose is in the range used in some small trials.

Prebiotics and probiotics

The fibre blend feeds gut bacteria, and the probiotics include Bacillus subtilis and Lactobacillus strains, according to the label. Two grams of fibre is modest compared with the 25 to 30 g many adults are advised to eat daily.

Allergies and sensitivities

The label includes mushroom, chicory and fruit fibres. People allergic to mushrooms or sensitive to inulin should be cautious. The page does not list common allergens in a separate statement.

Dissolving

Instant powders with fibre and mushroom extract can clump. The page recommends a frother or whisk, and customers say it mixes in hot or cold water.

Storage

Keep the bag tightly sealed in a cool, dry cupboard, away from the kettle and any rising steam while cooking. Moisture makes powders clump and may reduce probiotic counts over time. Use the scoop dry.

Taste expectations

Customers describe the flavours as delicious and fruity. Yerba mate's natural taste is grassy and slightly bitter, so the fruit flavours and sweeteners do a lot of work. People who dislike stevia's aftertaste may notice it.

Caffeine timing

The page suggests mornings or midday. Caffeine's effects peak within an hour and fade over several hours, so a mid-morning drink suits most people best.

Flavours

The page offers Peach Mango, Strawberry Matcha and Piña Colada. The Strawberry Matcha flavour suggests matcha in that version; check its label for any extra caffeine.

Serving size

One scoop is 11 g, with 30 servings per bag, according to the label. Doubling the scoop, as one customer does in a large tumbler, doubles caffeine to 200 mg and the cost per drink.

What it cannot do

It cannot cause weight loss on its own, repair skin from the inside, or replace a balanced diet. It is a caffeinated drink with added ingredients.

Who it's for

Yerba Magic suits coffee drinkers who want a flavoured, low-sugar alternative, yerba mate fans who want something instant, and anyone curious to try lion's mane and L-theanine in a daily drink. It does not suit people sensitive to caffeine or who are pregnant or breastfeeding without advice, anyone buying it for weight loss or skin, people on interacting medicines, or budget-focused drinkers.

• Coffee drinkers who want a flavoured, low-sugar alternative
• People who like yerba mate but want something instant
• Anyone curious to try lion's mane and L-theanine in one drink

Why Yerba Magic appeals

Many people want energy without the sugar of energy drinks or the acidity of coffee. A fruity iced drink with coffee-level caffeine and wellness ingredients fits neatly into that gap. Customers on the page say it replaced their drive-through coffee habit.

People who dislike coffee's taste

Some people want caffeine but not coffee's bitterness. Fruity iced flavours are a different experience, closer to a soft drink.

People who get acid reflux from coffee

Some people find coffee aggravates reflux. Yerba mate is also acidic and caffeinated, so it may not be much better. Try a small amount first.

Coffee drinkers cutting back

Swapping one coffee for a scoop of Yerba Magic gives similar caffeine with a different taste. It does not reduce total caffeine unless you drink less overall.

Energy drink drinkers

Compared with sugary energy drinks, Yerba Magic has far less sugar and a more modest caffeine dose than many large cans. That is a genuine improvement for regular energy drink users.

Tea lovers

Yerba mate drinkers who like its taste may enjoy the flavoured versions, though the fruit flavours change the character of traditional mate.

Students and shift workers

People who need alertness at irregular hours often lean on energy drinks. A lower-sugar caffeine drink is a better habit, but caffeine late in a shift can wreck sleep afterwards.

Fitness enthusiasts

Some people drink caffeine before workouts. A 100 mg serving can help performance a little. The fibre may not suit a sensitive stomach right before exercise.

People who want a habit swap

Some customers describe it replacing a daily drive-through coffee. If that also replaces a sugary syrup drink, the sugar and calorie savings can be meaningful over weeks.

People who take medicines

Some medicines, including certain antibiotics, antidepressants and heart medicines, interact with caffeine. Lion's mane may also interact with blood-thinning or diabetes medicines in theory. Ask a pharmacist if you take regular medication.

People managing blood sugar

At 2 g of sugar and 9 g of carbohydrate per serving, it is lower in sugar than many drinks. People with diabetes should still count the carbohydrates and check how sweeteners affect them.

Older adults

Older adults can be more sensitive to caffeine and more likely to take interacting medicines. Half a scoop is a sensible start.

Pregnancy and breastfeeding

Health bodies generally advise limiting caffeine during pregnancy to around 200 mg a day. One scoop provides half that. The other ingredients have not been studied in pregnancy, so ask a midwife or doctor first.

People with anxiety or palpitations

Caffeine can worsen anxiety and trigger palpitations in sensitive people. L-theanine may soften that a little, but it does not cancel caffeine's effects. Start low or avoid it if caffeine affects you badly.

Who should skip it

Skip Yerba Magic if caffeine makes you anxious or disrupts sleep, if you are pregnant or breastfeeding without medical advice, or if you take medicines affected by caffeine. Skip it if you want weight loss or clearer skin from a drink. And skip it if loose yerba mate or coffee at home suits your budget better.

• People sensitive to caffeine, pregnant or breastfeeding without medical advice
• Anyone buying it for weight loss or skin improvement
• People on medicines that interact with caffeine or with mushroom allergies
• Budget-conscious drinkers who are happy with loose yerba mate or coffee

Do Yerba Magic's ingredients work? What the evidence says

The caffeine works; the other ingredients have modest or limited evidence. One hundred milligrams of caffeine reliably boosts alertness. L-theanine may smooth caffeine's effects in small studies. A 2025 systematic review of lion's mane found small cognitive improvements in a few trials, mainly in older adults, and called for more research. The fibre and probiotics may support digestion, but no study tests this product.

Who funded the evidence

The page cites no studies of its own formula. Evidence comes from separate research on individual ingredients, often at different doses and in different forms from those in the drink.

Caffeine

Caffeine improves alertness and reaction time for most people. The FDA's guide on how much caffeine is too much cites 400 mg a day as an amount not generally associated with negative effects for most adults, while noting that sensitivity varies widely.

Lion's mane

A 2025 systematic review in Frontiers in Nutrition included five randomised trials and three pilot trials. Cognitive scores improved slightly in some groups, including people with mild cognitive impairment. Most studies were small, and doses and forms varied.

What lion's mane might do

Lab studies show compounds in lion's mane can stimulate nerve growth factors. Whether that translates to noticeable focus improvements in healthy adults drinking it daily is not established.

L-theanine

Small studies suggest L-theanine combined with caffeine can improve focus and reduce jitteriness compared with caffeine alone. Effects are modest and vary between people.

Prebiotics and probiotics

Fibres like inulin feed gut bacteria, and some people find they help regularity. They can also cause gas and bloating at first. Probiotic effects depend on the strain and dose, and 500 million CFU is a modest amount.

Inulin and bloating

Inulin is a common prebiotic fibre. In some people, especially at first, it causes gas and bloating. Customers on the page report less bloating; individual responses vary widely.

Caffeine and sleep

Caffeine has a half-life of several hours, so an afternoon drink can still affect sleep at night. People who sleep poorly should keep caffeine to the morning.

Weight and metabolism

Caffeine slightly raises energy use and can briefly reduce appetite. Those effects are small. A customer review mentions weight loss alongside eating healthily and exercising, which is where most of the effect would come from.

Probiotic survival

Probiotics in powdered drinks must survive storage and stomach acid to reach the gut. Bacillus subtilis forms spores that survive better than many strains. The page does not say how CFU counts are guaranteed through the shelf life.

Gut health in context

Gut health depends mainly on overall diet, especially plenty of fibre from vegetables, fruit, beans and whole grains. A daily drink adds a small amount. It is not a substitute for a varied diet.

Safety of lion's mane

The 2025 review aimed to build a safety profile and noted that lion's mane is an edible mushroom with few reported side effects in trials. Allergic reactions are possible. Long-term daily use in healthy people has not been studied much.

Probiotic strains

The label lists Bacillus subtilis and several Lactobacillus strains, including acidophilus, casei and plantarum, at 500 million CFU in total. Many probiotic supplements contain billions of CFU, so this is a low dose.

What the FDA does not review

Supplements and functional drinks are not approved by the FDA before sale. The asterisks on the page point to the standard disclaimer that claims have not been evaluated by the FDA.

Mate and health research

Yerba mate has been studied for antioxidants and effects on fat use during exercise, with mixed and mostly small results. Very hot mate drinking has been linked with oesophageal cancer risk in some studies, linked to temperature rather than the plant, so avoid scalding drinks.

Skin

The page says it supports glowing skin from the inside out. No ingredient here has good evidence for that at these doses.

What this means for you: buy it as a tasty caffeine drink, and treat the gut and focus ingredients as possible extras.

Are Yerba Magic's claims accurate?

The core label is clear, but several marketing claims stretch. "Clean energy", "no crash" and "brain fog buster" are subjective. "Supports metabolism, weight goals and skin" is not supported for this product. Badges claiming number one bestseller status on Amazon and TikTok, "500K+ units sold" and "loved by 30k+ people" are not sourced on the page.

"Clean energy without the crash or jitters"

Caffeine from yerba mate is the same molecule as caffeine from coffee. L-theanine may soften jitters. A crash depends on how much caffeine you have and your sleep, not the source.

"Brain fog buster"

Caffeine reduces sleepiness and can make thinking feel sharper. Persistent brain fog has many causes, from poor sleep to medical conditions, which a drink will not fix.

"Gut health support"

Two grams of fibre and a modest probiotic dose may help some people a little. Customers report less bloating; others may find inulin causes bloating at first.

"Metabolism support"

The FAQ says Yerba Magic supports metabolism and weight goals. Caffeine slightly raises metabolic rate for a few hours. The effect is small and similar to coffee or tea.

"Better than coffee, matcha and energy drinks"

The page's comparison chart ticks every box for Yerba Magic. Coffee and matcha have their own benefits and long research histories. The chart is marketing, not a test.

"Ready in 10 seconds"

The comparison chart says it is ready in 10 seconds. With a frother, that is about right. Stirring with a spoon may leave clumps.

"Combats bloat"

Graphics on the page say it combats bloating and creates "zero stomach drama". Inulin can do the opposite for some people. Individual responses vary, so try a small amount first.

"Quality you can feel"

A page graphic says the yerba mate is premium and unsmoked. Some traditional mate is smoke-dried, which gives a smoky flavour; unsmoked mate tastes cleaner. The claim describes taste and processing rather than health.

"Low sugar, just 2 grams"

The label lists 2 g of total and added sugar per serving, with allulose and stevia for sweetness, and cane sugar among other ingredients. That is genuinely low.

Bestseller badges

The flavour images carry "Amazon #1 selling yerba mate" and "TikTok #1 bestseller" badges. Such rankings can be category-specific or short-lived. The page gives no dates or categories.

"Loved by 30k+ people" and "500K+ units sold"

Different figures appear across the page. No source is given for any of them. The on-site review count of 2,076 is the only figure tied to visible reviews.

"Real reviews, real results"

A graphic shows smiling customers and short quotes. As with any seller's quotes, these are chosen to show the product at its best.

"How long does it take to feel results?"

The FAQ says energy comes immediately and other benefits build over one to two weeks. The caffeine part is accurate. Gut and wellness changes over that period are possible but not demonstrated for this product.

"Produced in USA"

The page says produced in the USA, with yerba mate sourced from South America. We could not verify the facility.

"Non-GMO" and "plant based"

The page says plant based and non-GMO. Those are reasonable claims for a plant-derived drink with fibre and mushroom ingredients, though probiotics are bacteria, not plants.

Customer quotes

Recent reviews on the page praise taste, fast shipping and energy without a crash. One mentions weight loss and reduced appetite alongside a healthy diet. Reviews on a seller's own site tend to be more positive than independent platforms.

Reviews on the page

The store's review widget showed 4.70 out of 5 from 2,076 reviews on 5 October 2026, mostly five stars. These are on the seller's own site. We found no Trustpilot page for yerbamagic.com.

How much does Yerba Magic cost, and can you return it?

The store's product listing showed $39.99 for a 30-serving bag on 5 October 2026, about $1.33 per serving. The page also offers two- and three-bag discounts, 25% off a first subscription order and 10% off recurring orders, with free US shipping. The refund policy allows returns within 30 days of receipt in the same condition, but excludes sale items.

Prices as seen

When we visited from India, the page displayed prices in Indian rupees, with the per-bag price falling for two and three bags. The store's product data listed $39.99 per 30-serving bag for each flavour. US buyers should check the final price in dollars at checkout.

Cost per month

At one scoop a day, a bag lasts a month. At full price, that is about $40 a month, or less with multi-bag or subscription discounts. A daily coffee shop drink often costs far more.

Compared with coffee and loose yerba mate

Home-brewed coffee or loose yerba mate costs well under $1 a serving. Coffee shop drinks cost several dollars. Yerba Magic sits between them, paying for convenience, flavour and the added ingredients.

The return policy

You have 30 days after receiving your item to request a return by emailing help@brainista.com. The item must be in the same condition as received, with proof of purchase. If accepted, the company sends a return label. Sale items and gift cards cannot be returned. Refunds are processed within 10 business days of approval.

The sale-item exclusion

The page shows the product at a discount. If that counts as a sale item, it may not be returnable, despite the "30-day easy returns" message on the page.

What to do: ask help@brainista.com whether discounted orders can be returned before buying.

Delivery

The page says US orders ship free and estimates delivery within a few days. International customers saw local currency prices, which suggests the store ships abroad, though the page focuses on US orders.

Contact details

Returns go to help@brainista.com. Include your order number, flavour, and reason for return. Do not send items back without first getting approval.

Same condition requirement

Returns must be in the same condition as received. An opened bag of powder is unlikely to qualify. If you are unsure about taste, buy a single bag rather than a bundle.

Bundles

Two- and three-bag bundles lower the price per bag. If you know you like yerba mate, a bundle saves money; if not, start with one bag, since opened bags are unlikely to be returnable.

Comparing per-serving value

To compare fairly with other functional drinks, divide the price by servings and check the caffeine, sugar and active ingredient amounts per serving. Yerba Magic's clear label makes that easy, which is a point in its favour against brands that hide doses in proprietary blends and give buyers far less information to go on when comparing.

Gifting

The page says it is great for gifting. A bag suits friends who like fruity iced drinks, but check they are comfortable with caffeine first.

Currency display

The page showed prices in Indian rupees when we visited from India, so buyers outside the US may see local prices and conversion. Check the currency and total before paying.

Price in context

At about $1.33 a serving at full price, a month's supply costs about $40. That is less than a daily coffee shop habit and more than brewing coffee or mate at home.

Subscription terms

The subscription offers 25% off the first order and 10% off recurring orders. Read how often it ships and how to cancel before subscribing, so you are not charged for bags you do not want.

Return labels

If a return is accepted, the company sends a return shipping label, according to the policy. That suggests return postage may be covered, though the policy does not say so outright.

Damaged or wrong orders

Contact the company immediately if an order arrives damaged, defective or wrong, as the policy asks. Photos help.

Subscriptions

Subscriptions auto-ship refills. Check how to pause or cancel before signing up, so you do not receive more than you need.

Is Yerba Magic better than coffee, matcha or plain yerba mate?

For taste and convenience it competes well; for value and evidence, coffee and plain mate win. Coffee and loose yerba mate are cheaper and well studied. Matcha offers caffeine with natural L-theanine. Yerba Magic adds lion's mane, fibre and probiotics, which may or may not matter to you.

Yerba Magic vs coffee

Coffee has similar caffeine, a large body of research and a low cost at home. If you enjoy coffee and it does not upset your stomach, there is little reason to switch.

Yerba Magic vs plain yerba mate

Traditional mate brewed in a gourd or teapot is cheaper and has a stronger, earthier flavour. Yerba Magic is sweetened, flavoured and instant.

Yerba Magic vs a fibre supplement

If your main goal is gut health, a simple fibre supplement or more fibre-rich foods deliver far more than the 2 g per scoop here, at lower cost.

Yerba Magic vs a caffeine pill

Caffeine tablets give a precise dose for very little money, without flavour or extras. Some people prefer a drink for the ritual and hydration.

Yerba Magic vs green tea

Green tea has less caffeine, naturally contains L-theanine, and costs very little. For a gentle lift, it is a well-studied, cheap alternative.

Choose Yerba Magic if

You want a flavoured, instant, low-sugar caffeine drink, like the idea of added L-theanine and lion's mane, and are happy to pay a little extra for convenience. Choose coffee or plain mate if price matters most.

Yerba Magic vs bottled yerba mate drinks

Ready-to-drink canned yerba mate drinks are widely sold in shops, often with 120 to 160 mg of caffeine and some sugar. They are convenient but cost more per serving and create more packaging waste.

Yerba Magic vs Brainista mushroom coffee

Brainista also sells mushroom coffee products with lion's mane. If you prefer the taste of coffee, those may suit you better. Yerba Magic suits people who want a fruity, iced alternative.

Where Yerba Magic wins

Taste, convenience and low sugar for people who want a flavoured caffeine drink. The added L-theanine is a plus for those sensitive to caffeine jitters.

Where it loses

Price per serving and evidence for its wellness claims. Coffee and plain mate do the core job for less.

Yerba Magic vs energy drinks

Many energy drinks contain 150 to 300 mg of caffeine and lots of sugar. Yerba Magic's 100 mg and 2 g of sugar is gentler on both counts.

Yerba Magic vs matcha

Matcha naturally contains caffeine and L-theanine together. It takes a little whisking but has no added sweeteners.

Is Yerba Magic legit, and what should you check before buying?

Yes. Yerba Magic is a real product from Brainista, with a full supplement facts panel and a large number of on-site reviews. Before buying, count your daily caffeine, check medicines and health conditions, ask about returns on discounted orders, and judge it as a drink rather than a health treatment.

Count your caffeine

What to do: add up coffee, tea, energy drinks and Yerba Magic. Stay within your comfort level, and well under 400 mg a day for most adults.

Check medicines and conditions

Caffeine interacts with some medicines and can worsen anxiety, heart rhythm problems and acid reflux. Ask a pharmacist if unsure.

Start slowly with fibre

If you are not used to inulin, start with half a scoop to let your gut adjust, which can reduce bloating.

How to buy Yerba Magic the smart way

1. Check your caffeine intake, then open the Yerba Magic order page (opens Brainista in a new tab).
2. Pick a flavour, or try one bag first.
3. Confirm the price in your currency at checkout.
4. Ask whether discounted orders are returnable.
5. Skip the subscription until you know you like it.

How did we score Yerba Magic?

Yerba Magic scores 5.6 out of 10: claim accuracy 0.8, build durability 1.2, price competitiveness 1.0, usability 1.6 and owner satisfaction 1.0, each out of 2. It earns usability points for a quick, low-sugar drink with a clear label. Points come off for weight, metabolism and skin claims, unsourced bestseller badges, modest evidence for lion's mane and probiotics at these doses, the price per serving and a refund policy that excludes sale items.

How the score breaks down

We use the five criteria on our how we test page, each out of 2.

What we did, and did not, do

Nobody on our team has tried Yerba Magic. We read the product page, label and FAQ on 4 and 5 October 2026, and the refund policy, FDA guidance, PubMed and Trustpilot on 5 October 2026. Our supplements hub lists other supplements we have reviewed, including the Emma Relief review. For a single-ingredient algae powder, see our Zivolife Sticks review.

How to use Yerba Magic for the best results

Mix one scoop into cold water with ice, or warm water, in the morning or early afternoon, and avoid it within six hours of bedtime. Start with half a scoop if you are sensitive to caffeine or fibre, count it in your daily caffeine, and drink water alongside.

1. Start with half a scoop to judge caffeine and fibre.
2. Use a frother for a smooth mix.
3. Drink before mid-afternoon to protect sleep.
4. Count caffeine from all drinks.
5. Drink water alongside.
6. Eat breakfast if caffeine upsets your stomach.
7. Store sealed in a cool, dry place.

Mixing with milk

Some people add oat or dairy milk to fruity powders for a creamier drink. The page suggests water, and acidic fruit flavours may curdle dairy, so try a small amount first.

Exercise days

On workout days, a scoop about 30 to 60 minutes before exercise gives caffeine time to take effect. Avoid it if fibre upsets your stomach during exercise.

Making it last

If one scoop is too strong, use half a scoop in a large glass of water. The bag then lasts up to 60 drinks, halving the cost per serving.

Hydration

Caffeine has a mild diuretic effect, but a drink made with water still contributes to hydration. Keep drinking water through the day, especially in hot weather.

Track how you feel

Note your energy, sleep and digestion for two weeks. If nothing beyond the caffeine effect stands out, a cheaper caffeine source may serve you just as well.

Hot or iced

The page suggests both. A customer enjoys it either way, and another doubles scoops in a large tumbler, which also doubles the caffeine to 200 mg.

Mixing flavours

Customers mix flavours, such as piña colada with mango. Keep total caffeine in mind when using more than one scoop.

Other questions about functional yerba mate

Can I drink it every day? For most healthy adults, one scoop a day is a moderate caffeine dose.

Is it vegan? The page says plant based; check the label for details.

Can teenagers drink it? Caffeine limits are lower for teens; ask a doctor.
