Company Profile

Omega Alpha Pharmaceuticals Inc. is 100% Canadian owned and incorporated in Ontario, Canada. Omega Alpha opened its doors immediately after receiving its GMP license in October 1992 with the goal in mind to provide consumers with scientifically formulated natural health products manufactured using pharmaceutical standards. Twenty years ago, there were very few Canadian companies using research-based science at the heart of their practices. The company is proud to be a leader in natural health products based on science.

Dr. Gordon Chang, CEO of Omega Alpha Pharmaceuticals Inc. received his Ph.D. in 1989 from the University of Toronto, Department of Physiology and Institute of Biomedical Engineering where he received a research fellowship award from The Hospital for Sick Children to research cell adhesion, biomaterials and blood material interactions. Later, as a post-doctoral fellow at the department of Clinical Chemistry at Toronto General Hospital, Dr. Chang led research in antioxidants, free radical chemistry and oxidative injury. He established Omega Alpha Pharmaceuticals Inc. in 1992 and his manufacturing company has earned rewards, accolades and the enduring respect of his peers for producing innovative and efficacious herbal-based and nutritional supplements for the natural health industry.

Many companies produce herbal formulations, but Omega Alpha manufactures supplements based on proven scientific research and testing. The company manufactures nearly 300 natural health products through five divisions: Consumer Health Products, Pet Health Products, Equine Health Products, Professional Naturopathic Health Products through their Alpha Science Laboratories™ brand, and Professional Veterinarian products through their AlphaVet Science™ brand.

Products are clinically evaluated by, and in consultation with, master herbalists, pharmacists, veterinarians, medical doctors, and naturopathic doctors. At their on-site laboratories, they test all ingredients and formulations before, during and after manufacturing and batch testing to ensure that there are no heavy metals, contaminants or other toxins, and they also utilize third party laboratories to verify the efficacy, safety consistency and purity of their products.
