Buffered Vitamin C (with Bioflavonoids)

Write a review

A powerful antioxidant, vitamin C is a water-soluble vitamin necessary to form collagen in bones, cartilage, muscle and blood vessels. It also aids in the absorption of iron. We use only USP-quality (99.5% or higher purity) vitamin C, with a pH equal to 2.4. For patients who want to supplement their diet with additional vitamin C, our buffered formulas combine low-acidity potassium/ magnesium ascorbate with lemon bioflavonoids including hesperidin and rutin.

  • Powerful antioxidant
  • Gentler on sensitive stomachs

What is Buffered Vitamin C with Bioflavonoids?

Designed specifically for individuals sensitive to acidic foods and beverages, Buffered Vitamin C 500mg and 1000 mg with Bioflavonoids is a combination of two mineral ascorbates (potassium and magnesium) that supply the essential antioxidant vitamin C without increasing stomach acidity.  

Vitamin C is a potent water-soluble antioxidant and essential in the human diet as it cannot be synthesized within the body [1]. Vitamin C is an electron donor, and this property is closely related to all of its known functions [1]. Vitamin C is required for the production and maintenance of collagen. It has anti-inflammatory properties, supports the immune system, contributes to the healthy production of neurotransmitters, and aids in the absorption of iron.

Lemon bioflavonoids have been added for increased bioavailability.


How does Buffered Vitamin C with Bioflavonoids Work?

The stability and formation of collagen, the major protein from which connective tissue, cartilage, bone, skin, tendon, and tooth dentin is made, requires a vitamin C-mediated process [2]. A lack of vitamin C, a required cofactor for prolyl hydroxylase, impairs the development of collagen and renders humans “scorbutic” [2]. The human phenotype of vitamin C deficiency, “scurvy” classically involves fragility of blood vessels [2].

In addition to its antiscorbutic actions, vitamin C has potent antioxidant properties. Antioxidants protect and aid in the repair of cellular damage caused by free radicals/reactive oxygen species. In response to physical trauma, vitamin C exerts a protective effect on neutrophil-mediated cell injury by scavenging reactive oxygen metabolites [3]. Vitamin C concentrations in plasma and immune cells rapidly decline during infections and stress signifying its use is upregulated for immune support [4]. Multiple clinical studies have shown that supplementation of vitamin C improves components of the human immune system [4]. Vitamin C also plays a role in the maintenance of healthy circulation and has anti-inflammatory effects [2]. 

Of all the body’s organs, the adrenal glands accumulate the highest levels of vitamin C [5]. Animal models have shown the role of vitamin C in these tissues is crucial to survival [5]. Ascorbic acid is a cofactor required for the biosynthesis of and the catecholamine neurotransmitters, epinephrine, norepinephrine, and dopamine, as well as adrenal steroidogenesis [5]. 

For those consuming plant-based diets (no animal tissue), vitamin C is the only known dietary constituent that can significantly increase the absorption of nonheme iron [6]. It is important to note, the stimulating influence of ascorbic acid on iron absorption has been demonstrated to be most pronounced when ascorbic acid is consumed with food [6].

Flavonoids, and specifically hesperidin and rutin, work synergistically with vitamin C, as ascorbates are more readily absorbed in combination with flavonoids than they are when taken alone [7]. Flavonoids also have antioxidant and anti-inflammatory properties of their own.


What are the Suggested Uses for Buffered Vitamin C with Bioflavonoids?

  • Nourishes tissue growth and repair as a collagen support nutrient.
  • Supports adrenal and immune function, bolstering immune cells and contributing to the production of catecholamines.
  • Powerful antioxidant for free radical protection and repair.
  • Can increase absorption of iron from food.
  • Gentler on sensitive stomachs than classic ascorbic acid vitamin C supplements
