Integrate the following: A vegan athlete reports fatigue and difficulty recovering after endurance sessions. Their diet includes legumes, nuts, leafy greens, and no animal products. Which combined strategy best addresses potential vitamin-like nutrient insufficiencies relevant to performance and recovery?

• A. Advise immediate high-dose lipoic acid and inositol injections as the sole remedy because these two nutrients replace all other metabolic functions disrupted by a vegan diet.
• B. Recommend elimination of legumes and leafy greens because plant sources cause fatigue, replace with a high-sugar energy drink regimen to compensate for any micronutrient deficiencies.
• C. Assess dietary intake for carnitine and choline shortfalls, consider targeted supplementation or inclusion of fortified foods, ensure adequate protein and methionine to support endogenous choline synthesis, and monitor performance and markers of muscle metabolism.
• D. Tell the athlete that no dietary changes are needed because endogenous synthesis of all vitamin-like nutrients always meets demands during heavy training regardless of diet.

Answer: (C)
