Comments about Source Naturals Methylcobalamin (1 MG) - 120 Tablets:

I take this once a day after reading about how most vegetarians and vegans need more vit. B12 than they are getting and lack of vit. B12 can lead to lethargy, sleep problems, etc.

Despite supplementation with food items containing B12 like nutritional yeast, I was still experiencing extreme tiredness and insomnia so I figured, "can't hurt," and bought the 120 count bottle and take this daily. This is a form that is easier for some people to break down in their bodies.

It's been fantastic! My sleep problems are not 100% solved but now I am now able to get up on a semi-regular morning/evening cycle and I have a LOT more energy. I can concentrate much better on tasks such as reading as well. The dreaded "vegan brain fog" is gone!

I would recommend this to anyone but ESPECIALLY vegans or vegetarians who are supplementing with B12 in other forms but still feeling really lethargic. I saw a marked result in about two weeks.

Only con would be that it tastes rather chalky and takes a while to dissolve completely under the tongue, more than 15 min.

      I'll continue using these. They are sublingual, and are the active form of B12.
