Supplement↕ | Category↕ | Claimed Benefit↕ | Evidence Level↕ | The Debate↕ |
|---|---|---|---|---|
Creatine Monohydrate | Performance | Muscle strength, power output, brain function | Strong | Most researched supplement ever, actually works, cheap, still people think it's a steroid |
Vitamin D3 | Vitamin | Bone health, immune function, mood | Strong | 50%+ of the world is deficient, sunshine vitamin, but optimal dosage is hotly debated (1000 IU vs 5000 IU) |
Omega-3 (Fish Oil) | Essential Fatty Acid | Heart health, brain function, inflammation | Moderate-Strong | Eat fish instead? Fishy burps, some studies say minimal benefit, others swear by it, EPA vs DHA debate |
Magnesium | Mineral | Sleep, muscle recovery, stress relief | Moderate-Strong | 300+ enzymatic reactions, most people are deficient, glycinate vs citrate vs threonate wars |
Protein Powder (Whey) | Macronutrient | Muscle building, recovery, convenient protein | Strong | Whey vs casein vs plant protein, is it 'cheating'? Kidney damage myth, chalky taste memes |
Zinc | Mineral | Immune support, testosterone, wound healing | Moderate | Cold-shortening claims, testosterone boost is marginal, too much causes copper deficiency |
Ashwagandha | Adaptogen | Stress reduction, cortisol lowering, sleep | Moderate | Ayurvedic herb gone mainstream, KSM-66 studies promising, some report emotional blunting |
Caffeine | Stimulant | Energy, focus, athletic performance | Strong | Most consumed psychoactive substance, tolerance buildup, pre-workout culture, is coffee enough? |

Melatonin | Hormone | Sleep onset, jet lag, circadian rhythm | Moderate | 0.5mg vs 10mg dosing debate, not a sleeping pill (it's a timing signal), long-term safety unclear |
Iron | Mineral | Energy, oxygen transport, anemia prevention | Strong (if deficient) | Essential for menstruating women and athletes, but excess iron is dangerous, test before supplementing |
B12 | Vitamin | Energy, nerve function, red blood cells | Strong (if deficient) | Vegans NEED this, elderly often deficient, but energy drink marketing oversells it for non-deficient people |
Turmeric / Curcumin | Anti-inflammatory | Joint pain, inflammation, antioxidant | Mixed | Bioavailability is terrible without piperine, golden milk trend, thousands of studies but many low quality |
