Are there Effective Vegan-Friendly Supplements for Optimizing Health and Sports Performance? a Narrative Review

Veganism, characterized by the exclusion of all animal-derived products, has grown in popularity due to ethical, environmental, and health considerations. However, vegan athletes often face unique nutritional challenges related to dietary deficiencies of critical nutrients such as proteins, vitamin B12, iron, calcium, and omega-3 fatty acids, among others. This narrative review aims to explore the efficacy and benefits of vegan-friendly supplements specifically tailored to athletic performance, focusing on essential micronutrients, ergogenic aids, and nutrient bioavailability.

Nineteen key supplements are discussed, including protein powders, creatine, beta-alanine, caffeine, vitamin B12, vitamin D, omega-3 fatty acids, zinc, calcium, iron, iodine, vitamin K2, selenium, probiotics, nitrates, electrolytes (including sodium and potassium), taurine, vitamin A, and magnesium. Evidence suggests that the integration of these supplements into personalized nutrition plans can bridge dietary gaps while addressing specific performance needs, potentially leveling the competitive field for vegan athletes. Recent studies also highlight research gaps in sex-specific needs, synergistic effects, and strategies to enhance the bioavailability of nutrients from whole foods. Vegan diets, while conferring various benefits, require careful consideration of nutrient intake for athletes seeking optimal performance. Personalized biochemical assessments should be considered when possible for tailoring specific nutritional guidelines for each case. This narrative review provides practical guidelines for clinicians, nutritionists, trainers, sports scientists, and athletes to design personalized supplementation strategies that address common nutritional shortfalls, enhance performance, and serve as a foundation for future research in vegan sports nutrition.
