Who should avoid hyaluronic acid supplements?

EFSA judged rooster comb extract, a source of hyaluronic acid, safe at the use its maker proposed, up to 80 mg a day. The maker's target group was the general population, except three groups: pregnant women, children and people who react to sodium hyaluronate or to bird protein.^[1] People in the excluded groups should ask a doctor or pharmacist first.^[1]

People who take medicines every day should also ask first, because some dietary supplements interact with prescription or non-prescription medicines.^[2]
