Almost perfect

I can actually tolerate this b12 I'm c677t het with other yuck mutations. The price is a bit step but if it works might be worth it.

Thanks for your feedback!

Love this bioavailable form of B-12

I use this form because of genetic methylation issues with other forms.

Thanks for your feedback!

Effective but expensive

Posted by iHerb Customer on December 17 2017 | Verified Purchase

Fast dissolving, nice tasting, and very small tables. The hydroxy form was prescribed by my naturopath. Blood levels are good on these. The bottle is huge compared to the contents, with the tablets only covering the bottom of the bottle in 2 layers. I will be complaining to the manufacturer about this. I only buy this brand when the Source Naturals hydroxocoabalamin is out of stock. The SN is also cherry flavored, larger tablets but still small compared to most supplements, a little longer to dissolve, but are in an appropriate sized bottle and less than half the price!

Thanks for your feedback!

Great Product But Such Wasteful Packaging

Posted by iHerb Customer on December 4 2017 | Verified Purchase

Very easy way of beating MTHFR chronic fatigue issues but wow such wasteful packaging... the tiny tabs only just cover the bottom of the large bottle... it could be so much smaller or even better fill the bottle up so I don’t have to order more so quick!!

Thanks for your feedback!

Effective and tasty

Posted by iHerb Customer on November 29 2017 | Verified Purchase

Effective sublingual tasty formula, providing top absorption. Very efficient form of B12. As a bonus does not contain mannitol which annoys people with IBS.

Thanks for your feedback!
