My Fav form of B12

Methylcobalamin made me feel very weird and gave me anxiety -- this is the type found in muscles and used in mitochondria. If the methyl form makes you feel bad, try this or hydroxocobalamin.

Good product

A great product from seeking health. Easy to take and in theory the absorption is improved by slowly allowing the lozenge to dissolve. I also do regular methylcobalamin shots and this form adds other benefits on top of this by supporting and protecting the mitochondria which the methylcobalamin cannot do.

Seeking Health B12 is the best

Quality, small size to easily dissolve. Good ingredients. I need extra B Vitamins and B12 is usually lacking (I have hypothyroidism and adrenal fatigue) and Adeno works best for me. No weird effects. Hoping that by upping my dosage will help my nervous system due to its potency. More energy is definitely needed. Thank You iHerb for carrying this brand. I have been using Seeking Health products for years.

Expensive, I tried it and it's not better than Swansons. I actually prefer Swansons Hydroxo-Adeno B12.

Clean Cellular Energy & Focus

Pure adenosylcobalamin that delivers a smooth, steady lift in mental clarity and stamina — no overstimulation, just clean mitochondrial energy. The lozenges dissolve easily with a mild taste. Noticeable brain sharpness after regular use. Ideal for those who respond better to adeno-B12 than methyl forms.

good

I can just recommend this product, taking it regularly. I was very defficient of B12 vitamin and after 6 month of taking this and similar B12 products it got to the normal range. I can recommend it! Good quality and high potency with maximum effect.

I have mixed impressions about this product, it's good, but this dose seems to be too strong for me, because when I take it, my head feels a little uncomfortable.

Great

I have tired a lot of b12 supplements, and I like that this brand offers multiple types of b12 and folic acid for people who have trouble absorbing them. I like how this brand chooses quality ingredients and puts a lot of thought into optimal absorption. These are potent with 3,000 mcg of b12, so the brand recommends starting with half a tablet.

Best type of b12

I noticed great energy improvement when I switched to this b12. I trust this brand as I use several of their products to keep histamine under control. Always highest quality
