Frequently Asked Questions

Do I need to supplement with vitamin B5?

Most people do not need B5 supplements because pantothenic acid is found in virtually all plant and animal foods — the name literally means "from everywhere." Deficiency is extremely rare in developed countries. Supplementation is primarily relevant for pantethine (cholesterol support) or topical panthenol (skin care), not for preventing deficiency.

Does pantethine really lower cholesterol?

Clinical trials show pantethine at 600-900 mg/day modestly reduces total cholesterol (11%), LDL (12%), and triglycerides (17%). While these effects are statistically significant, they are smaller than statin medications. Pantethine may be a reasonable adjunct for mild dyslipidemia or for those who cannot tolerate statins, but should not replace statins when medically indicated.

Does high-dose B5 help with acne?

A 1997 hypothesis by Dr. Lit-Hung Leung proposed that megadoses (5-10 g/day) of pantothenic acid reduce acne by improving fat metabolism in skin. Some anecdotal reports support this, but rigorous RCTs are lacking. At these extreme doses, digestive side effects are common. More effective evidence-based acne treatments exist, including topical niacinamide (vitamin B3) and retinoids.
