Helping athletes to select botanical supplements for the right reasons: A comparison of self-reported reasons for use versus evidence-based supplement claims

Use of food supplements (FS) by athletes is well characterised but there is little information on ‘herbal’ or ‘botanical’ FS beyond ‘natural’. This study determined, by questionnaire, whether athletes' main self-reported reason for using FS was reflective of what was written on product labels or, when these claims were unavailable, was in accordance with the scientific literature. In 217 elite (n=55) and amateur (n=162) athletes living on the island of Ireland, 71% (n=153) consumed any kind of FS, with 16% (n=34) of the entire cohort deemed botanical consumers. ‘Protein’ (21%, n=46), ‘vitamin D’ (17%, n=37) and ‘vitamin C’ (15% n=32) were most consumed with the top reasons for use being ‘to support health’, ‘to prevent illness/for immunity purposes’ and ‘recovery’. There was generally good agreement between approved nutrition and health claims for such products and athletes' main reported reasons for use. Only the amateur athletes in our pool described using botanical supplements, with reasons for use stated as ‘sleep improvement’ (21%), ‘recovery’ (14%), ‘supporting health’ (12%) and ‘energy’ (12%), resulting in poor agreement with either approved claims or scientific evidence. Only half of amateur athletes knew if their botanical FS were third-party tested. Athletes and practitioners require guidance to avoid consuming supplements for which there is little scientific evidence, and which may risk being contaminated/ fraudulent
