Adherence

Bodybuilders who consume dietary supplements primarily rely on trainers and nutritionists for information sources rather than medical doctors, leading to the use of common supplements like Vitamin C, Vitamin D, and Whey protein.

If you are a bodybuilder, be aware that your supplement choices are heavily influenced by your trainer and nutritionist. Ensure these sources are well-informed about the latest research, as they are your primary information channel. Common supplements like Vitamin C, Vitamin D, and Whey protein are widely used, but verify their necessity and dosage with a qualified professional.
