Rated 5 out of 5 by from Excellent vegan option. I've used this brand for years and find it reliable in quality. Easy to swallow. Good ingredients. Always super fresh and ships quickly from Swanson's. Great price, especially with discounts during sales.

Rated 5 out of 5 by from B 12 Most of the vitamin B 12 I have tried does nothing! Doctor's Best works wonders just within a weeks time you will notice a difference.

Rated 5 out of 5 by from Essential! Excellent product, wouldn't ever be without it - provides me with energy, well-being, great mood & clear skin. Taken daily, it works as well as bi-weekly b-12 injections. The Methyl-Cobalamin form of B-12 is far superior to Cyanocobalamin, found in most oral B-12 supplements. Absolutely cannot beat the price!!

Rated 5 out of 5 by from Doctor's Best B12 I like the product Doctor's Best B12 and use it everyday. It definitely gives me the extra bit of energy I need for the day. I highly recommend it.

Rated 3 out of 5 by from I tried this product after reading a review that said B12, or the type of B12 that would be better for the particular supplement they were describing was methylcobalamin, instead of cyanocobalamin(which I had been taking for years). I can think of 3 reasons why I did not have a positive reaction from B12-methylcobalamin: 1) Not everyone reacts to medications, supplements, vitamins in the same manner. 2) I was at the time, unaware there were 2 types of B12 and having taken cyanocobalamin for many years, my body is used to it; plus I do not react well to time-released substances. In other words, I am cognizant of what B12-cyanocobalamin will do for me, I recognize the effect. Maybe I was anticipating the same from B12-methylcobalamin and therefore was unaware of any positive influence it may have produced. And 3) Possibly it is not very good? I don't like stating that though because of my first reason; it may work great for another?

Rated 4 out of 5 by from Least fillers I chose these because they had the least amount of fillers (corn, soy, rice). I would recommend this product.

Rated 5 out of 5 by from Way to go Doc Best Go with methyl B-12, over the cyanocobalamin, and go with Doctor's Best, because it is free of sugar alcohols (xylitol), lactose, and magnesium stearate--anti-nutrients--and is exactly what I was looking for.
