PRO-C (180 caps)
Originally designed more than two decades ago by Dr. Hank Liers, PRO-C is a powerful Vitamin C and free-radical protection supplement. It’s a potent source of Vitamin C (non-GMO ascorbic acid) that’s precisely buffered by calcium malate and magnesium malate. PRO-C is designed with ingredients that promote fast, easy absorption.
PRO-C is a cutting-edge Vitamin C and antioxidant nutritional supplement. Designed by Dr. Hank Liers, PRO-C serves dual purposes: it’s a potent Vitamin C formula and a powerful antioxidant. PRO-C was designed by Dr. Liers to enhance general health, immunity, rejuvenation, anti-aging, and all medically-recommended applications requiring free-radical defense. The nutrients in PRO-C have been selected and balanced to provide free radical protection, detoxification, immune system enhancement, and connective tissue strengthening.
- PRO-C contains Vitamin C (as non-GMO Ascorbic Acid) and buffering minerals in the form of powdered calcium and magnesium malate. In addition, PRO-C includes high potency whole grape extract (from seed, skin, and pulp), green tea extract (>45% EGCG), reduced glutathione, n-acetyl-l-cysteine (NAC), alpha-lipoic acid, zinc (from citrate),coenzyme forms of Vitamin B2 and Vitamin B6, and selenium (from l-selenomethionine).
- The grape extract and green tea extract in PRO-C contain bioavailable bioflavonoid complexes shown to have powerful antioxidant capability. The oligomeric proanthocyanidins of grape extract strengthen collagen fibers in aging or damaged connective tissue and can act as a preventative against connective tissue degradation.
- Glutathione and NAC (a major precursor of glutathione) both provide important protection against toxins and free radicals, and can strengthen the immune system. alpha-Lipoic acid is a potent fat-soluble and water-soluble antioxidant with important metabolic and detoxification properties.
- Selenium has been shown by clinical research to be a key mineral in the body’s defense against free radicals. Vitamin B2, Vitamin B6, magnesium, zinc, and calcium synergistically work with (and enhance the effects of) the other ingredients in this product.
PRO-C is a Foundational Supplement.

Works well too expensive
GREAT product! It really does thicken my hair, adds shine and helps it to grow, but requires taking three pills a day for over a month to see results!
bioAllers Mold, Yeast & Dust
I lost some hearing in my right ear which causes vertigo. Well mind vertigo alleviates the dizziness and quiets the upset stomach.
I have taken ArthroMax this year for joint comfort and mobility. It has definitely helped with flexibility and ease of motion for my hip joint. I recommend this product for people who need a little extra help for mild osteoarthritis.
This is a great value. It is processed well and does not have anything added unnecessarily. I have been using this for a while now and it has helped with my digestive issues.
Does what it is supposed to.
I have tried so many supplements and I have not found that they helped in any way. I have severe panic attacks. Along with all the other meds that I take this one really helps to calm my system.
Men's 55+ Advanced Multivitamin
Tastes great and I never forget to take my vitamins!
Great product!
