My Favorite Metagenics Product

This is my favorite product from Metagenics! I bought this bottle for my daughter & we're still waiting for it to arrive.

The product is good. I’m very disappointed in the ordering process. I’ve repeatedly signed up for auto reorder to get the discount. It hasn’t worked.

Immune Active

Although love Metagenics products, I could not use this one as it gave me very, very painful gastrointestinal upset, and unfortunately I had to stop using it. However, my husband is using it without incident which I am very happy about.
