Micronutrients & recovery
Vegans exhibit a high prevalence of dietary inadequacy for vitamin B12 and iodine when relying solely on food sources, necessitating supplementation or fortified foods to maintain adequacy.
If you follow a vegan diet, you must actively manage your Vitamin B12 and Iodine intake. Food sources alone are often insufficient. Use a B12 supplement (considering absorption limits and dosing frequency) and ensure your iodine sources (like iodized salt or specific supplements, as UK salt is often not iodized) are adequate. Do not assume plant-based diets automatically provide these nutrients.
The results suggested a high prevalence of inadequacy for dietary vitamin B12 and iodine in vegans.
Why this rating
Large cohort (n=30,251), cross-sectional design, validated FFQ, but self-reported supplement use and potential under-reporting of energy intake limit causal certainty.
