Vitamin B12 supplements come in several forms. Bioavailability matters so that you get the benefits. Whether you have MTHFR or are a vegan looking to prevent vitamin B12 deficiency, you want the best vitamin B12 supplements.
That’s why Seeking Health B12 comes in several bioavailable formulations that are gluten-free and non-GMO. You can get B12 from foods (mostly animal products), but vegans and vegetarians need to supplement. Even if you have high dietary intake, you may still benefit from supporting B12 levels with a supplement.†
Methyl B12 1000 and Active B12 5000 contain methylated and coenzyme forms of B12 (methylcobalamin and adenosylcobalamin), making these the most potent, active B12 supplements we offer.
If you want a non-methyl supplement, Hydroxo-Adeno B12, Hydroxo-B12, and Adeno B12 all provide high doses without the active form of vitamin B12. Adenosylcobalamin and hydroxocobalamin still readily convert to active forms in the body, so you are still getting the bioavailable nutrients that you need. You can choose capsules or lozenges.†
