Ashwagandha
Marketing claims: "Boosts testosterone," "Eliminates stress." Reality: Studies show modest testosterone increase (15-17%) primarily in stressed/infertile men, not healthy adults. Stress reduction is well-supported but requires 600mg/day for 8+ weeks. Single low doses show minimal effect.
Vitamin B12
Marketing claims: "Energy booster," "Mood support." Reality: B12 only provides energy if you are deficient. For those with adequate levels, extra B12 is simply excreted — expensive urine. Blood tests can confirm deficiency before supplementing. High doses (5000mcg+) offer no advantage over 500-1000mcg.
