"1,000mg taurine dose supports performance"
This dose matches amounts used in taurine exercise trials, unlike many competitors that underdose it.

"Magnesium and calcium support muscle function"
50mg magnesium and 84mg calcium are far below doses used to treat deficiency, just a minor top-up.

"Enhance athletic performance"
Electrolytes fix dehydration, but the product's own performance claim overstates plain hydration science.
Consumer advice
If you sweat heavily during workouts or in hot weather, this product delivers legitimate, well-dosed electrolytes and a solid taurine amount. But if you're just trying to stay hydrated day-to-day, a cheaper electrolyte mix or even water with a pinch of salt and a banana for potassium does most of the same job. Skip the subscription flow if you're not sure you'll use it regularly - the free sample pack lure isn't worth locking into recurring billing if you might cancel after one order. Check the linked COA if you want proof of what's actually in the tub.

Why the chain breaks for this product
Most ingredients below have real research behind them. The problem isn't the ingredients — it's the doses. 4 of 9 are not disclosed on the label, so the product can claim the benefits without delivering the chain that gets you there.
SenActiv
Antioxidant amino acid derivative. Animal studies show it reduces oxidative stress and protects cells.
Research-backed dose: 50mg (matches studied dose)
In this product: 50mg
Amino acid with antioxidant and neuroprotective properties. Human evidence is limited and mixed.
Research-backed dose: 1000-2000mg used in studies
In this product: 1000mg
Essential mineral for bones and teeth. Widely under-consumed, especially in athletes and dancers.
Research-backed dose: RDA ~1000mg/day; 84mg is a minor contribution
In this product: 84mg
Magnesium (Aquamin Mg)
Essential minerals that regulate hydration, nerve function, and muscle contraction. Critical for recovery after heavy exercise.
Research-backed dose: 200-400mg for magnesium supplementation benefits
In this product: 50mg
Dried coconut water. A natural source of electrolytes, but clinical evidence for benefits is very limited.
Research-backed dose: Not a clinically dosed 'active' ingredient - more of a flavor/minor mineral contributor
In this product: 500mg
Essential mineral with roles in mood, nerve function, and heart health. Evidence is mixed depending on the condition.
Research-backed dose: 250-350 mg/day based on study doses
In this product: Dose not disclosed
Dried coconut water with natural electrolytes. Marketed for hydration, but clinical evidence is very limited.
Essential mineral. Limited direct supplement trial data; one RCT suggests modest blood pressure support.
Research-backed dose: 300 mg/day (supplement form); 3,500–4,700 mg/day total dietary intake per general guidelines
In this product: Dose not disclosed
Essential mineral for bones and teeth. Widely under-consumed, especially in athletes and dancers.
Safety & side effects
What NIH says about the ingredients in this product. This describes the ingredients, not tests of this product, and it is not medical advice. Ask a doctor or pharmacist first if you take medication, are pregnant or nursing, or have a health condition.
Magnesium
Magnesium from food poses no health risk in healthy people, because the kidneys clear the excess. High doses from supplements or medications can cause diarrhea, nausea and abdominal cramping, and very high doses can lead to toxicity.
Possible side effects
- High doses from supplements or medications can cause diarrhea, nausea, and abdominal cramping.
- Magnesium carbonate, chloride, gluconate, and oxide are the forms most commonly reported to cause diarrhea.
Serious risks
- Very high doses can lead to magnesium toxicity, with low blood pressure, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest and other signs.
- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
Avoid or ask a doctor first if
- People with impaired kidney function or kidney failure face higher risk of magnesium toxicity.
- People taking medications regularly should discuss their magnesium intake with their health care providers.
Medication interactions
- Magnesium may interact with oral bisphosphonates, tetracyclines, and quinolone antibiotics.
- Some medications, including diuretics and proton pump inhibitors, can affect magnesium status.
Upper limit: 350 mg a day for adults 19+. This label lists 50mg.

Potassium
This page says little about potassium safety. The section on risks from excessive potassium is empty, and no upper limit is given. It does warn that some medications can affect potassium status in dangerous ways.
Avoid or ask a doctor first if
- The recommended intakes don't apply to people whose bodies clear potassium poorly, for example because of kidney disease or certain medications.
- People taking medications that affect potassium should talk with their health care providers about their potassium intake and status.
Medication interactions
- Several types of medications can affect potassium status in ways that could be dangerous.
