I have heard of others using this product, but I am not familiar with it, at all...
The description there doesn't really explain what it is either. At best, it's a multivitamin. You should go for the calcium and multivitamin. Use the calcium with D3 if you use a florescent strip UVB or the calcium without D3 if you use a MVB.
Like everyone said, it seem a bit pricey, well not really.. less than $15 for a long time's worth of supplements. But, it truly will last a loong time!
