Alpha Base® Capsules without Iron by Ortho Molecular Products

If you’re looking for a multivitamin without iron, this fits men, post‑menopausal women, and anyone with high Ferritin (the protein that stores iron) or a history of iron intolerance. It’s also a good base if your Vitamin D, 25-Hydroxy is low-normal, B12 or Folate run low, or Homocysteine (a methylation byproduct linked to B-vitamin status) is elevated. Hemochromatosis and frequent blood test–guided phlebotomy patients often use iron-free formulas. Pregnant individuals or those with known iron deficiency should choose a prenatal or a multivitamin with iron instead.

This multivitamin uses methylfolate (Quatrefolic), the bioactive folate form that bypasses common MTHFR enzyme variants, paired with methylcobalamin (active B12) to help normalize Homocysteine within 4 to 12 weeks. It combines vitamin K1 with K2 MK‑7 (longer-acting vitamin K for calcium handling) alongside vitamin D3 for bone and vascular balance. Minerals are chelated (glycinate/malate forms), which are better tolerated and absorbed than oxides. You also get mixed tocopherols (vitamin E family) and 200 mg of chelated magnesium, useful if your dietary magnesium is light.

Take 4 capsules daily with food, ideally split 2 with breakfast and 2 with dinner to improve absorption and reduce nausea. Fat-soluble vitamins (A, D, E, K) absorb better with a meal containing some fat. If you’re tracking labs, recheck Vitamin D, 25-Hydroxy, B12, Folate, and Homocysteine after 8 to 12 weeks. This is a maintenance multivitamin; if your Vitamin D is significantly low, you’ll likely need higher-dose D3 short term under clinician guidance, then step back to this.

Warfarin users should clear this first, as vitamin K can counter its effect; newer blood thinners are not vitamin K–sensitive. Separate from levothyroxine, tetracyclines, and quinolone antibiotics by at least 4 hours because minerals block absorption. The chromium and vanadyl sulfate can enhance insulin action; if you use insulin or sulfonylureas, monitor glucose. The iodine amount suits most adults, but those with active thyroid nodules or thyroid autoimmunity should keep iodine intake consistent and coordinate with their clinician.
