HelloPharmacist Scorecard of BCAAs Caffeine Free Berry Lemonade by Gnarly Sports Nutrition

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 6 of its 6 active ingredients.
  • “BCAA Blend” is a proprietary blend — the label gives one combined amount (5 Gram(s)) without saying how much of each component you get.

This powder contains 5 active ingredients: three branched-chain amino acids (L-leucine, L-isoleucine, and L-valine—collectively called BCAAs, amino acids your muscles use for energy and repair), potassium (an electrolyte that supports nerve and muscle function), and Aquamin (a natural mineral source). The rest is inactive ingredients—natural flavors, sweeteners, acids for taste, and thickeners that make the powder mix and taste good.

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: pre-workout and muscle recovery support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We hold no effectiveness ratings for any of the active ingredients in this product in our data, so we can't tell you whether the evidence supports BCAAs or potassium for your specific goal. The facts don't include what condition or outcome this product is meant to address, so talk with your pharmacist about what you're hoping it will do and whether the science backs it.

The evidence, ingredient by ingredient Black Psyllium Potassium

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Potassium from food is generally well tolerated and safe. Potassium supplements, though, can cause problems in some people—especially those with kidney disease—because they may lead to dangerously high blood potassium levels.

The most common side effects from potassium taken by mouth are stomach upset: abdominal pain, nausea, vomiting, diarrhea, and gas. Rare but serious effects of very high potassium are heart rhythm problems, low blood pressure, and confusion.

For pregnancy and breastfeeding, the potassium in this product is rated likely safe. The three branched-chain amino acids and Aquamin don't have pregnancy or breastfeeding safety data on file, so talk with your doctor or pharmacist before using this during pregnancy or while nursing if you have specific concerns.

Side effects, ingredient by ingredient Black Psyllium Potassium

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Black Psyllium, Potassium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 2,026 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your medications against this product if you take potassium-sparing diuretics (water pills labeled 'sparing'), ACE inhibitors, or angiotensin receptor blockers (ARBs)—all carry a Moderate risk of dangerously high blood potassium when combined with potassium supplements. We could not check the three branched-chain amino acids or Aquamin against our data.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in BCAAs Caffeine Free Berry Lemonade with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Likelihood Possible Evidence B

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

BCAAs Caffeine Free Berry Lemonade by Gnarly Sports Nutrition: Common Questions

Does BCAAs Caffeine Free Berry Lemonade by Gnarly Sports Nutrition interact with any medications?
Yes. Based on its ingredients, BCAAs Caffeine Free Berry Lemonade has a known interaction with 2,025 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
BCAAs Caffeine Free Berry Lemonade contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is potassium from this supplement the same as potassium from food?
No, not quite. Potassium from a normal diet is fine—your body handles it well. Supplements deliver higher amounts and can cause dangerously high blood levels in some people, especially those with kidney problems. Use supplements only under your doctor's guidance.
What are BCAAs, and what do they do?
BCAAs—branched-chain amino acids—are three amino acids (L-leucine, L-isoleucine, L-valine) that your muscles use for energy and repair. We don't have effectiveness data on file for this product, so ask your pharmacist whether the evidence supports using them for your goal.
Can I take this if I'm pregnant or breastfeeding?
Potassium is rated likely safe in pregnancy and breastfeeding. We don't have safety data for the BCAAs or Aquamin, though, so talk with your doctor or pharmacist for personalized advice.
What side effects might I notice?
Most common are stomach upset—nausea, vomiting, diarrhea, gas, or belly pain. Serious side effects from high potassium levels are rare but can include heart rhythm problems, low blood pressure, and confusion.
Is this safe if I have kidney disease?
Potassium supplements can be risky with kidney disease because your kidneys may not handle high potassium well, leading to dangerously high blood levels. Talk with your doctor before using it.
