China-FREE Vitamin C
Drink-mix Formula w/Lysine & Proline
"If the claims for vitamin C are correct, it might replace many lucrative and expensive medications. As they researched their book ASCORBATE, Hickey and Roberts began to wonder if Pauling's offense had been to discuss openly the properties of a substance that threatens the profitability of medicine."

Cardio-C™ makes Linus Pauling's recommended dosages of vitamin C and lysine easier - no pills.

This potent formula is the only Vitamin C Foundation Approved® Pauling-therapy™ drink mix.

Frozen to Preserve Freshness

Why We Freeze Cardio-C to Preserve Freshness - and Why You Should Too

We freeze more than half of every batch of Cardio-C that we receive from the bottler. Usually this means that Cardio-C you get from us is fresh, no matter what the manufacturing date is on the bottom.

Vitamin C Foundation Every once in a while a bad Cardio-C jar will be sent out. We will replace it at no charge. If you happen to receive a bad jar (i.e., hard or clumping contents), it probably means the seal was faulty and some air got in. Take a picture of the open jar, email to us at vitamincfoundation@gmail.com and we will send you a new jar free of charge.)

Frozen for Freshness

The cost imposed on nutritional suppliers by new federal GMP regulations forces us to order large batches of Cardio-C. In a matter of months, any moisture trapped inside the jar causes the powder to clump, This is why you should keep the desiccants that come in the jar - in the jar.

The amino acid proline in the mixture is the culprit. Proline absorbs and reacts with moisture and begins to clump reducing shelf life. A chemist informed us that freezing stops this reaction w/moisture, and our tests show this to be the case. This is also why if you order several jars, we recommend storing any unopened Cardio-C™ jars in the freezer.

To our knowledge we are the only ones freezing our Pauling therapy product to preserve freshness.

Lp(a) Binding Inhibitors

Vitamin C and the amino acid lysine are two dietary supplements that Linus Pauling patented as Lp(a) Binding Inhibitors.

Pauling/Rath Patents

Pauling's therapeutic claims have yet to be clinically studied by modern medicine.


Use at your own risk. Neither the FDA nor the Medical Profession accept the proposition put forth by Pauling, Rath, Levy and others that the root cause of cardiovascular disease is an acute vitamin C deficiency at the site of the arterial lesion.

The NonProfit (VitaminCFoundation.ORG) Does Not Sell Vitamin C.
