Bad product quality
I bought L-Serine at request of my MD. I noticed that the L-Serine turned brown after a few days. I didn't think about calling them for a few weeks as I was trying to figure this out as to why. But, when I did call them...it was past the 30 days. The customer service woman couldn't have cared less and was extremely rude. She had no concern that one of their products had turned brown. This indicates manufacturing problems with this specific product but I wonder about their other products now. I threw it out. I am now buying all my other packages from another company and their L-Serine does not turn brown.
