I like that it has 2 active B-12's. Lozenge is smaller than Jarrow's so it has less sugar alcohol. Jarrow uses xylitol which is a little higher glycemic than sorbitol/mannitol. I am sensitive to all sugar in the morning. I would prefer stevia. This Source Naturals B-12 melted in about 10 minutes. It melts faster than Jarrow b-12 (20 min. melt approx). I prefer Jarrow's glass bottle and cap better over Source Naturals bottle caps/neck. I like screw caps/necks like Jarrow or Doctor's Best bottles. I use B-12 with Country Life coenzyme B complex. I also use Natural Factors B-12.
Excellent to help with energy levels

I started taking this about 8 months or so ago. I have allowed myself to run out only once. I can definitely tell when I have not been taking it, as I am not able to run on less sleep or go full throttle if I have not been taking it. I did research on the best sources of B-12 and this one contains both of the two recommended, most usable sources. I have recommended this to others as well. I am placing another order right now for this. It is also one of the most reasonably priced and dissolves quite quickly. I am a firm believer in this product!

I have been taking these for 2 months now. I have a history of depression, and since I have been taking these, I have not had a bout. I take Nexium for acid reflux and it depletes the Vitamin B in your system. This has been a great supplement for energy and mood!
Got 30 tablets, not 60!

When I opened the box it felt to light, and I was expecting 60 tablets, but then I count them. to my disappointment I found only 30 tablets! I love Source Naturals, but this gave me a warning sign not to buy them again, unless someone in Iherb will compensate me.

I needed more B-12, and this sublingual variety seems to be helpful. And, it is pleasant to take.

these take a long time to dissolve and i don't get the energy boosting effect like i would from these ones by solgar.

I highly recommend this. It has a good energizing and mind clearing effect for me.

Much better than methylcobalamin alone, fantastic energy from this one!

I am glad that this is high potency B12 and also has folic acid, taking it under the tongue it takes about 10 mins. to dissolve completely, I usually take it after I have taken all my other supplements. My blood tests show that I have good amounts of vitamin B12 and folic acid. This B12 seems to be the best for absorption(there are 2 kinds). God bless you all.
