Zinc
Marketing claims: "Immune booster," "Testosterone support." Reality: Zinc only boosts immunity or testosterone if you are deficient. Excess zinc (>40mg long-term) can cause copper deficiency and actually suppress immunity. Most multivitamins provide adequate zinc — standalone supplements often provide excessive doses.
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.
