What customers are saying...

I am a repeat customer of BIOS Tryptophan. My dog recently needed surgery and was experiencing anxiety even after giving the prescribed pain meds.

She was extremely restless, breathless, and paced the floor, whimpering. She was weak with exhaustion, frequently toppling over, but couldn't settle down. I called my vet and told him the situation and asked if I could give her some L-Tryptophan.

He said, "Absolutely" it will relieve her anxiety and likely let her sleep. I gave it to her and she calmed right down in about 1/2 hr. and slept 8 hours with only one waking to go out for potty.

Just a wonderful product to have in the natural medicine arsenal. Thank you.
