Works better when put between the gum and lip - no sugar alcohols (but does contain lactose). Note: high doses of B12 may deplete iodine, iron, zinc, manganese

I don't tolerate mannitol/sorbitol used by other brands but the small bit of lactose in this seems OK. I found this one works better when put between the gum and lip - under the tongue it dissolves too fast. I'm going to try California Xtracts and Jarrow Formulas instead. 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) Source Naturals methyl-B12 1mg sublingual - contains mannitol and sorbitol. 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.

I have been using this product for 5 months and it has made a significant difference to my energy levels and sleep pattern. Have also recommended it to my sister who is anaemic, she is much better after taking this B12.
Excellent form of B-12!

This is the only form of B-!2 I will use because all others make me ill. I have been taking it for over three months now and see an amazing difference in my energy level. I have seven kids and am studying for my MPH degree. Believe me, this product works.
Great energy boost!

Within two days of taking these tablets, my husband's "restless leg" problem simply disappeared. He has now taken them for 17 days and the dizziness that has plagued him for years (upon standing up) has almost completely gone - thank you!
