Experts Urge Caution on 7 Popular Supplements as Evidence Stays Mixed and Risks Persist
1 articles · Updated · The Jerusalem Post · Jun 7
Summary
Seven widely used supplements — including collagen, melatonin, probiotics, Turmeric, ashwagandha, Biotin and energy boosters — drew expert warnings over uneven evidence, inconsistent product quality and possible side effects.
Melatonin may help people fall asleep faster but not sleep better, while dosing varies by person and some products contain amounts that do not match their labels.
Probiotics, collagen and turmeric show mixed or limited benefits because effects vary by individual, studies are inconsistent, or the body poorly absorbs the active ingredient.
Ashwagandha has limited short-term evidence and possible liver or thyroid effects, biotin offers little benefit without deficiency and can distort blood tests, and stimulant supplements can raise heart rate and blood pressure.
Experts said supplements can help in specific cases, but a balanced diet and professional guidance remain the safer default than adding every new product to a routine.
