this is the best b complex ive used, and ive used all kinds, including all natural b complexes from food, lypo-speric b complexes, and coenzymated bs that are not sublingual. ive noticed this formulation and delivery method alone is able to provide the slight thermogenic effect (due to increased metabolism of sugars from cocarboxylase thiamine.) this product has alot of the b's in a form the consumer usually can only wish they would produce upon consuming a regular b complex; but the fact is, and has certainly been in my experience, that the body is unable to coenzymate b vitamins in the therapeutic quantity i take them in supplementally on a consistant basis. this product has also raised my energy, whereas ive noticed other b vitamins would simply be dicarded via the urine quickly. i am however dissapointed that the product contains folic acid instead of a 5 methylfolate, especially in light of all the bad press synthetic folic acid is getting these days, and i also consider their choice to include calcium pantothenate instead of the coenzymated pantethine to depreciate the product, as pantethine has only been shown to stimulate the adrenals when it is brought directly into the bloodstream, as a sublingual would accomplish. i for one would pay more for this product were these adjustments made to master it

The first time I took one, i was pretty shocked by the strong taste. To me they tasted bitter, like a really bitter grapefruit really. I don't taste the orange in them at all. But after taking two or three, I don't mind the taste at all. They're actually pretty tasty now and they work really well. If I take an entire pill I seem to dream all night, so I have backed down to only half a pill and day and it's just perfect.

This B Complex is absorbed directly into the bloodstream since it's disolved sublingually. I really like this vitamin B complex for that reason. It's very bioavailable. The taste is fine for the most part, but has a very very slight bitterness beneath the orange flavoring. One drawback is that sometimes it seems to take a long time to dissolve, especially if I'm in a hurry in the AM. It also makes my teeth yellow if I don't rinse them. Because of this, I sometimes opt to take New Chapter's B complex instead. If I have the time, I definitely prefer the Source Naturals B Complex though due to its superior bioavailability. My partner cannot be bothered and takes the New Chapter B.

Have been taking this for a couple years now. Every time I stop I feel it...less energy, more lethargic, etc. Am a vegetarian so need to keep the B's up. Best B vit I've found, and only the sublingual seems to do the trick,
