Product Overview


  • Ortho¹ Science-Based Nutrition
  • Dietary Supplement
  • (MethylCobalamin)
  • Vegan

Best Fully Active B12 provides MethylCobalamin, the most biochemically active form of vitamin B12. Various inherited and lifestyle factors contribute to vitamin B12 deficiencies that impair such fundamental life processes as recycling of homocysteine, a potentially toxic metabolite; nerve cell signaling; mood and memory management; and healthy gene regulation (epigenetics), from pregnancy through old age. Best Fully Active B12 is vitamin B12 at its best.

  • Ortho¹ molecule identical to the body's fully active vitamin B12
  • Helps correct inherited and lifestyle-related B12 deficiencies
  • Supports healthy memory, mood, circulation and well-being

¹A nutrient naturally built into the body's chemistry.

Suggested Use

Take 1 capsule once daily with a meal. Higher intakes may be useful, as recommended by a nutritionally-informed physician.

Best Fully Active b12

Posted by 5182084093404958542 on Aug 04, 2016

a good valuebrand and mid range dose of bio active form of vit B12. When I found out I have issues with MTHFR genes I decided to try bio available B12. Glad I made the change as I definately feel more 'switched on' and energetic. I have also began to trial Doctor's Best Fully active B complex also with good results.

I think this product is pretty good, although honestly I think liquid/sublingual b12 is more effective. Haven't really noticed much of a difference but I don't think I've been using it for long enough. Will finish my bottle and probably continue with sublingual from then on.

Only one complaint: the bottle is tooooo big, just like chips with whole bag of air.
