Vegan Multivitamin by DEVA

If you follow a vegan or mostly plant‑based diet, a vegan multivitamin is a practical backstop for nutrients that are harder to get from plants. This formula suits vegans, vegetarians, and anyone eating a limited or low‑calorie menu who wants coverage for B12, iodine, zinc, and iron. It’s also a fit if your Vitamin D, 25‑Hydroxy (the blood test that reflects vitamin D status) or Vitamin B12 are in the lower range, or if your Ferritin (iron storage protein) trends low from heavy periods. Men and post‑menopausal adults with normal or high Ferritin usually do better with an iron‑free multivitamin.

This multivitamin uses cyanocobalamin (a stable, well‑studied B12 form) at 100 mcg to reliably raise B12 in vegans, and includes 18 mg iron for those who lose iron with menstruation. Iodine from kelp (150 mcg) supports thyroid hormone production. It provides vitamin D2 at 20 mcg; D2 works, but D3 from lichen generally raises Vitamin D, 25‑Hydroxy more efficiently, so add a D3 if your level is low. Minerals are present at modest doses—calcium carbonate 100 mg and magnesium oxide 40 mg—meant as a safety net, not as full repletion.

Take one tablet daily with food, ideally a meal that contains some fat to improve absorption of vitamins A, D, and E. If iron upsets your stomach, take it with the largest meal or at bedtime with a small snack. Separate it by at least two hours from coffee or tea, which can reduce iron uptake, and from any larger calcium or magnesium supplements that compete with iron. Recheck Vitamin B12, Methylmalonic Acid (a functional B12 marker), Ferritin, and Vitamin D, 25‑Hydroxy after 8–12 weeks to gauge response.

Space this multivitamin at least four hours away from levothyroxine for thyroid, and two to six hours from antibiotics like tetracyclines or fluoroquinolones, since iron and minerals bind them. Proton pump inhibitors and metformin can impair B12 absorption—this formula helps, but lab follow‑up matters. If you have hemochromatosis, chronically high Ferritin, or liver disease, choose an iron‑free multivitamin. Not a prenatal: it contains preformed vitamin A (retinyl acetate), so pregnant people should use a true prenatal and follow clinician guidance. Thyroid disease warrants caution with kelp‑derived iodine; monitor TSH (the pituitary signal that drives thyroid hormone production).
