dematica collagen complex

[cutecockerpoo12]

Hello I have an email regarding this product. I wondered how this compares to other collegen products on the market.
If I subscribe to it monthly it is £20 per month. It probably has postage on top.
Has anyone looked into it as a collegen product.

It’s only 5000mg - wellgard is the same price (albeit bovine rather than marine) for 13000mg

Is there differences in the marine over the bovine. I know nothing about them. But I have heard of marine.
