Fish burps
Size: 50 Count (Pack of 1), Style: Megared Algae Oil
This is my third bottle of the algae sourced and I had no problems with the first two. Now I am having fishy burps, yuck,! I tried changing the time of day I am taking it but that hasnt helped. I am glad to have a plant source option so will stick it out.

High Quality
My husband is deficient in magnesium and these by far looked like they were of the highest quality . Not sure yet if they help him sleep better but will be purchasing them again.
