Dislike the mannitol and sorbitol - going to try California Xtracts or Jarrow Formulas. Note: high doses of B12 may deplete iodine, iron, zinc, manganese

1) Pure Advantage methyl-B12 spray - ineffective (I wonder about the sorbate preservative in it); 2) InterPlexus Inc NutriSorb liquid hydroxycobalamin - effective but still needs to be 'converted' to active form - I found the one drop dose suggested on label isn't enough; 3) Solgar cyanocobalamin 1mg sublingual - dissolves too fast and not as effective as active methyl-B12; 4) Natural Factors methyl-B12 1mg sublingual - dissolves too fast under tongue but found it better inbetween gum/lip where it will sit and dissolve more slowly. Iodine/B12 are synergists - suggest adding/increasing either one if taking more of the other, especially long term. Same is true of other nutrients such as manganese and zinc (both need cobalt, high cobalt may deplete them) - could be why some people note headaches after taking high doses of B12 (both high and low manganese can cause migraine-headaches). High doses of B12 will also deplete iron - they are antagonists. If this review was helpful to you, please click YES below - thank you.

The roles B-12 play in the body are numerous and vital. Vegetarians in particular (and especially vegans) should take this supplement, even if they are of the mindset that vitamin pills are silly, because B-12 is found almost exclusively in animal products. Additionally, it is difficult for some to absorb (the elderly and some with various health conditions) as it is only absorbed in one part of the intestine. Finally, alcohol consumption creates a situation where extra supplemental B-12 is beneficial. Anyway, about this product in particular. I have always liked the brand Source Naturals as they make my favorite multiple, which is why I purchased this. It seems to fit the bill. It's the MethylCobalamin type (which is the preferred structure), and they are sublingual (which aids in absorption), and it is an adequately large dose (1mg, which is about 16000% of the RDA). The tablets dissolve slower than other brands I've used, which can be slightly annoying, but the company claims that this is for better absorption. Overall, a fairly decent product, with a light pleasant cherry taste.

Combined with extra B6, the Life Force Multiple and some fish oil, this B12 contributed to the elimination of chronic back pain, depression, arthritis, carpal tunnel syndrom. Source Naturals is a quality manufacturer.
Good quality and price

If taken sublingualy it makes you more alert. 1 mg is just good for me. If I take two I would feel a bit too alert and a little tensed.

Seems to work fine. Have noticed I feel more alert and less fatigued. I think I'm sleeping better and waking more refreshed.
