My medicinary includes only the best pharmaceutical grade supplements at the lowest price from companies that only sell to doctors. I keep my prices at a lower cost than what you can find online for the same quality product. There are a lot of poor quality supplements on the market today. Therefore, i advise all my patients to be very careful when buying fish oil, probiotics, and herbal medicine because the quality of what is on the market today will do more harm then good. It will generally cost a little more to buy quality but it is important for optimal health.
