Subject: NOW Foods is the Leading Brand for Amino Acids in Health Food Stores

It was recently announced that NOW Foods is now the leading brand for the amino acid segment in Health Food Stores. We sell over 100 different formulas of single and multiple amino acids in powder, capsule, tablet, and liquid forms. We cover the alphabet from L-Arginine to L-Tyrosine, with high potency products such as Acetyl L-Carnitine 750 mg, 1,000 mg L-Carnitine Tartrate, and our new 1000 mg L-Tryptophan Tabs coming in June. Most amino acids come in two optical forms – the L-form and the D-form. The L-form is the only true natural form, while the more common D- and DL-forms are synthetic. At NOW Foods, we only carry the natural L-form. This is the safest form, naturally found in foods and in the human body. Taurine and Glycine have no optical rotation, and therefore occur in only one natural form with no L- or D- designation.

Our L-amino acids are of the highest quality available, and our ingredient powders conform to USP standards. The USP standards cover identity, purity and potency testing. This means that each lot of amino acid ingredient is tested to ensure that (a) it really is the amino acid we say it is, and not something else, (b) it’s pure to the highest USP standards, and (c) it has the full potency that you require. At NOW Foods, we take our amino acids seriously, and we even go beyond the USP level of testing when we believe it is necessary. For example, every lot of our L-Tryptophan is tested to ensure that it is free of Peak E. This is the impurity which is believed to have been responsible for serious adverse events twenty years ago. We rigorously enforce this standard, and this goes beyond USP requirements. We have rejected a number of lots of L-Tryptophan because of the presence of Peak E. We will not sell you these rejected materials, and we hope that others do not as well. We can’t control what others do, but we can control what we do and we assure you of L-Tryptophan tested to be free of Peak E.

Our state-of-the-art analytical labs allow us to perform our own testing on our amino acids to doubly ensure their quality. We have 9 HPLCs that we use every day to test and retest our aminos to confirm their potency, purity and identity. We have very strong analytical, professional, and technical staff members who have many years of experience in testing amino acids. So much so that we are involved in developing industry validated methods for L-Carnitine and L-Arginine. NOW scientists are setting the standards for amino acid testing.

Most amino acids are quite stable and they can be packaged in standard containers. These amino acids will maintain their shelf life through their Best By date, and we test to make sure they do. SAMe however, is a uniquely unstable amino acid compound. Because of this, we provide triple protection – glass bottles, moisture control and oxygen control. SAMe is distinctly susceptible to oxygen degradation. We are the only major brand to offer our SAMe packaged with Ageless® oxygen absorbing packets, which remove integrity-challenging oxygen from every bottle to reduce degradation. We go that one step further to protect our products! Finally, we’re the leading amino acid brand because our products work. As an example, in a published study2, our SAMe was directly compared against the leading drug – Celebrex®.

NOW Foods brand SAMe performance was the same as the drug supporting joint health, but without the pharmaceutical side effects. All in all, we are not the leading brand in this category just because of our great prices. We have significant science and quality behind all of our products, not just amino acids, and we hope that you consider our rigorous efforts in quality assurance, safety and efficacy when making a purchase.
