Vitamin C is a vital antioxidant, protecting important molecules like proteins from damage by free radicals. But this essential vitamin does so much more, and nothing else can replace it.

Product Highlights:

  • Promotes a Healthy Antioxidant System*
  • Supports Immune Health*[1]
  • Maintains Cardiovascular Health, Blood Flow, and Endothelial Function*
  • Supports Brain Health and Neurotransmitters*[2]
  • Helps the Body Cope with Stress*
  • Facilitates Production of Collagen for Healthy Skin, Bones, and Tendons*
  • Increases the Skin’s Resistance to UV Damage*[3]
  • Reduces Histamine Reactivity*[4]
  • Supports Healthy Blood Sugar Levels*
  • Helps Maintain Healthy Alkalinity in the Body*
  • Supports an Active Lifestyle*

Vitamin C is water-soluble and easily lost from the body, so we need to consume it daily to get these benefits. Further, while vitamin C is found in vegetables and fruits, it breaks down easily during cooking and storage. That’s why Buffered Vitamin C is one of Dr. Morrison’s favorite supplements for overall health, to ensure you get enough of this important nutrient year-round.

The highest concentration of vitamin C in the body is found in the adrenal glands, which can get depleted during stress or intense exercise. Oxidative damage from pollution and the sun also deplete vitamin C.

Higher levels of vitamin C have been associated with a reduced risk of Alzheimer’s disease5 and Diabetes.6 In the cardiovascular system, vitamin C promotes collagen synthesis and antioxidant activity for blood vessel strength and function.7 In the skin, vitamin C may help provide natural SPF to keep your skin looking healthy and youthful.*[8] Buffered Vitamin C with added calcium, magnesium, and potassium may help reduce acidity in the body from the Standard American Diet of meat, dairy, processed foods, and simple sugars.9

Increased Absorption: Our popular Buffered Vitamin C is formulated with BioPerine®, a proprietary black pepper extract, to promote maximum bioavailability. The added minerals magnesium, potassium, and calcium reduce the speed at which vitamin C moves through the gastrointestinal system, allowing more time for optimal absorption.

Better Tolerance: While high doses of vitamin C are known to cause stomach upset and loose stools, we’ve added the buffering minerals magnesium, potassium, and calcium to reduce its acidity in the gut and support muscle relaxation. Buffered Vitamin C is a gentle formula that all our patients love, even those with a sensitive digestive tract.

Vitamin C Function in the Brain: Vital Role of the Ascorbate Transporter (SVCT2)

Effect of antioxidant intake patterns on risks of dementia and cognitive decline

Background: Folates play an important role to prevent neurological disorders in embryo development and in cardiovascular diseases. Folate supplementation is suggested, particularly in females of childbearing age, for the prevention of embryonal NTDs during pregnancy. Folic acid and reduced folate ((6S)5-MTHF) are currently used in supplementation. The aim of this study was to compare the bioavailability of Quatrefolic®, a novel patented (6S)5-MTHF glucosamine salt, with (6S)5-MTHF calcium salt and folic acid in Sprague Dawley rats.

Methods: Fifty-four to fifty-five-day old male Sprague-Dawley rats were divided in 3 treatment groups, each comprising 6 animals, receiving folic acid, (6S)5-MTHF calcium salt or Quatrefolic® at the dose of 70 µg/kg of (6S)5-MTHF equivalents in a single oral administration. Folates were determined in plasma with a HPLC method employing fluorimetric detection. (6S)5-MTHF level was chosen as a convenient end point to evaluate folate absorption. The main pharmacokinetic parameters were calculated (Cmax, tmax, AUC).

Results: Quatrefolic® administration produced a plasmatic (6S)5-MTHF concentration peak (Cmax: 879.6±330.3 ng/mL) 1.8 times higher than (6S)5-MTHF Ca salt (486.8±184.1 ng/mL), and 3.1 times higher than folic acid supplementation (281.5±135.7 ng/mL), while tmax values were similar for the three folate forms. Quatrefolic® supplementation showed AUC8h (1123.9 ng/mL ∙ h) 9.7 times higher than folic acid (114.7 ng/mL ∙ h) and 1.12 times higher than (6S)5-MTHF Ca salt (997.6 ng/mL ∙ h).

Conclusions: Quatrefolic® has demonstrated an enhanced oral bioavailability in comparison to other reduced folates and to folic acid in rats.
