Would this be a reef safe amino acid?

[VaReefer]

The amino acids sold for reef use are so over priced. would this be a reef safe amino acid? I am concerned with the zinc.

Is there any out there that reef keepers use that are cheaper then the reef branded ones?

I would stick to the aminos sold by companies like Brightwell or Kent and Seachem. They are actually comparable to what your looking at from Amazon. Plus you don’t have to worry about the guessing game as to how much to add and whether the zinc or chloride is going to hurt your tank or if the aminos are in an inappropriate level for a marine biotope. Plus, the aminos purchased and designed for marine use are aminos derived from marine fish and crustacean sources.
For piece of mind, I would not use aminos designed for human consumption in my marine systems.
