I researched a bit and found similar supplement to Algae cal for only $44 a month. Look at Garden of Life products.

I wonder if Algaecal actually helps with increase of bone density. That is the claim.

I can't seem to find anything out about it that wasn't written by someone associated with the product. I am wondering the same thing. It is kind of expensive to just try.

It’s Plant based rather than rock. There are more ingredients than calcium. Google it for more information.

How long have you been taking it and has it made any difference..Any side effects.
Cheers
