About Us
We have been providing people, professionals and businesses with the highest quality, U.S.P. grade, crystalline free form amino acids at the lowest possible prices since 1979.
We do all of our own encapsulating and packaging at our facility in Watsonville, California and stock most of the individual amino acids, amino acid formulas and other dietary supplements in both powder and capsule form. We can also help you with custom formulations and pride ourselves on our commitment to quality control and product purity, operating in cGMP compliant facilities.
Our friendly personalized service makes it easy for you to order what you need. Case discounts, private labeling, bulk quantities and custom formulations are easily arranged. We normally ship via USPS and UPS and have all UPS shipping options available.
