Vitamins and Supplements

Every manufacturer has two basic options when purchasing raw materials: purchase either truly pure raw materials, or purchase raw materials to which substances have been added to facilitate manufacturing.

There are three different grades of raw materials used in vitamins and supplements:

  • Pharmaceutical Grade: Meets Pharmaceutical standards just like non-generic brand name cholesterol medications, antibiotics and beta blockers. Pharmaceutical grade means 99% PURE.
  • Food Grade: Meets standards for human consumption. Just like crackers, cookies and manufactured baked goods found in the grocery store.
  • Feed Grade: Meets standards for animal consumption. Just like dry dog food.


Supplement Facts on the label do NOT always tell the facts. There have been recent studies that show vitamin and nutritional products do not contain the milligrams listed on the label. Many food grade and feed grade vitamins DO NOT have what they have listed on the label. This IS NOT ILLEGAL, they just do not have to monitored. That’s why we suggest Pharmaceutical grade vitamins and supplements.

A pharmaceutical vitamin or supplement needs to be 99% or more pure , free of binders, fillers, dyes or other unknown substances that may cause unwanted side effects. Vitamins and supplements should be bioavailable. Brands vary greatly; therefore bioavailability will also vary greatly with fillers and binding agents depending on the brand. In the simplest terms, bioavailability means that a vitamin or supplement should be absorbed and used by the body. Pharmaceutical grade vitamins must be at least 80% bioavailable. Food and animal grade vitamins and supplements do not have any standards.

As a newcomer to The Villages, I was in need of pain relief for my fibromyalgia. Dr. Cheshire had me doing cartwheels around my yard after 3 visits! I will never go anywhere else!
