This product only contains Methylcobalamin, not Adenosylcobalamin! Not happy!

Posted by 5302925651629501203 on Nov 28, 2015

I contacted Source Naturals to find out how much of this product is Adenosylcobalamin and was told that the product only contains Methylcobalamin! Not happy!! I am trying to recover from 25 years of migraines and have a double copy of the mthfr gene. It is hard enough to figure this out when you know what is in a product! I do not appreciate the deception in labeling by Source Naturals. If you buy any product from this company, first check that it is correctly labelled.

I take many forms of b12. Decided to try this one. I also take methylcobalamin. I wish iHerb would carry hydroxocobalamin.

great product

Posted by Reviewer1579775 on Feb 11, 2011

Recommended to me by a highly respected Naturopath. Certainly is doing the job and is actually enjoyable to take as it tastes great!

excellent product

great for pernicious anemia and a boost of energy. Like that it melts slowly. I would recommend this product. I no longer have to have my B-12 injections as often.

Another great tasting way to get B-12. These are definitely Source Natural's best tasting B-12 sublinguals! I am on automatic re-order. :)

High-dosed B12

Posted by 5431827020901947634 on Aug 15, 2014

Part of my B12 boost regimen. Combined with M-B12 literally makes me feel warm and glowy. Don't take it before going to bed, as you will feel (too) warm in bed. I take them in the morning with folate. With P-5-P.

active b's

Posted by healthysupplements on Apr 23, 2013

I was told that in order to help true healing of the CNS etc. with b vitamins that dibencozide along with methyl b12 is necessary. I was told that all active forms must be used to achieve success with long term healing of the nervous system. I am currently using all the active forms of vitamin b. The methylcobalamin is another important active form of vitamin b12.
