For the health and convenience of our patients at the Center for Optimal Health, we have made available the GNLD Webstore so that you can order / reorder your nutritional supplements our providers have recommended for you. Please order supplements according to your provider’s instructions. If you see products you are interested in, please contact your provider for personalized recommendation. We would like to make sure that we know all medications and supplements you are taking so that you can obtain the most benefit from your regimen while minimizing possible interactions and side effects.

Our medical director, Dr. Jannet Huang, after extensive review of supplement companies, has chosen GNLD products for not only our patients, but also for herself and her family. GNLD products have been utilized in USDA and university-conducted scientific studies resulting in a number of articles published in reputable, peer-reviewed journals.

GNLD's manufacturing arm, Natural Formulas, maintains a Drug Manufacturing License (#40708) issued by the State of California, Department of Health Services, Food and Drug Branch, even though they do not manufacture drugs. This license not only means that GNLD products are made to pharmaceutical standards, but that they maintain a strict adherence to Good Manufacturing Practices (GMPs). Additionally, every aspect of their operation is open to unannounced inspection by the FDA to confirm that they follow Good Laboratory Practices (GLP) as well as GMPs. While there is no law that requires supplement manufacturers, such as Natural Formulas, to meet the stringent standards required of drug manufacturers, GNLD voluntarily subject themselves to such scrutiny to help them assure the finest quality of products and to preserve consumer confidence. They have maintained their Drug Manufacturing License for more than 15 years.
