BioTech Pharmacal - C- Buff - 8oz

This stuff really seems to work. My dad and I both take it along with the Bio-Tech Vitamin D 50,000 unit pill and we have both noticed more energy and fewer colds. We got a cold one time and it was gone in 2 days. Normally we end up in the doctors office needing antibiotics after a week or two of struggling. I would highly recommend trying this. It will no doubt give your immune system an extra boost. We can attest to that.
