Benefit vs. Risk
⚠️ : not everything from the supplement shelf has the same ratio...
A recent narrative review usefully separates evidence-based nutrition from drugs, doping agents and contaminated products - but its risk claims often rely on mechanistic studies, case reports or high-dose misuse, not ordinary label-dose use.
💪 / : Clear benefit for meeting protein targets and muscle-protein synthesis; generally low risk in healthy athletes. "Kidney damage" concerns apply mainly to extreme intakes or pre-existing kidney disease, not normal sport-nutrition use.
⚡ : Strong strength/power benefit and robust safety record in healthy users. Expect water-weight gain; avoid casual use with known kidney disease and interpret creatinine blood tests appropriately.
☕ : Reliable performance benefit at roughly 3-6 mg/kg, but high doses can worsen anxiety, sleep, gut symptoms, blood pressure and acute cortisol responses. More is often worse, not better.
🥤 / : Valuable for long endurance events or repeated high-intensity efforts; the trade-off is individualized GI distress, especially with hypertonic drinks or bicarbonate.
🩸 / : High benefit when a blood test confirms deficiency; poor risk-benefit "insurance" when replete, where excess iron or vitamin D can cause harm.
🍒 / / : Possible soreness/recovery benefits, but performance effects remain uncertain; high-dose EGCG has liver-injury signals, while curcumin formulation and absorption vary wildly.
🦠 / / : Potentially useful in specific contexts, but strain/formulation-specific evidence is incomplete. Do not treat marketing as a protocol.
🚫 , , , , : High apparent body-composition payoff, catastrophically bad health and anti-doping trade-off: endocrine suppression, cardiac, liver and kidney risks, and potentially fatal toxicity.
There you have it... the summary of what you already knew, anyway - at least if you are a regular at the SuppVersity 😉
