OMG this is the best D3 product ever. It is tiny and tastes sweet. Reminds me of an old fashioned sugar pill. I put it under my tongue and it melts and goes into those veins that are so prominent in that area. D3 is so badly needed in our late middle age. I am 62. I do not look it even with the neurological diseases I have. As mentioned in my other posts, I have MS. So far my MRI has not developed any new lesions. WE WOMEN need D3 and this is a huge quantity in a tiny barrel shaped pill. OMEGA 3 I think is the working ingredient and I feel great these days.
