Who Needs Optimal Vitamin C Plus

Your body cannot make vitamin C. It must be obtained daily from your nutrition.

The buffered form of vitamin C can reduce digestive system discomfort from vitamin C supplementation. You can also enhance vitamin C’s activity by taking it with bioflavonoids. These plant compounds work synergistically alongside vitamin C to amplify its antioxidant effects.

Optimal Vitamin C Plus powder contains a potent serving of buffered vitamin C. Plant bioflavonoids are included to support vitamin C utilization.

Optimal Vitamin C Plus is ideal for those seeking an effective and well-tolerated immune support supplement. It includes naturally occurring bioflavonoids (quercetin and luteolin) from citrus fruits for additional antioxidant support. These plant bioflavonoids also enhance vitamin C’s effectiveness.

Each one scoop serving provides over 2,000% of the daily value for vitamin C. This essential vitamin supports numerous health benefits. Healthy immunity, skin, hair, nails, detoxification, and proper histamine metabolism are not possible without vitamin C.

This potent formula contains a well-tolerated, buffered vitamin C. By adding calcium and magnesium as buffers, it helps to reduce the GI side effects some people experience from high vitamin C doses. In conjunction with the bioflavonoid blend, the buffered form mimics the form of vitamin C found in nature for optimal utilization by the body.

Bioflavonoids are found naturally with vitamin C in citrus fruits and other food sources. When taken alongside vitamin C, bioflavonoids enhance vitamin C’s activity and provide synergistic benefits. Quercetin and luteolin enhance the cellular activity of vitamin C. These plant compounds also support healthy inflammation responses, antioxidant defenses, respiratory health, histamine metabolism, and cellular communication.

Optimal Vitamin C Plus supports healthy:

  • Aging and vitality
  • Antioxidant levels
  • Collagen production
  • Connective tissue and cartilage formation
  • DAO production
  • Detoxification
  • Enzyme function
  • Glutathione recycling
  • Histamine metabolism

Key Ingredients In Optimal Vitamin C Plus

  • Buffered Vitamin C: This form of vitamin C is ideal for those with sensitive stomachs. It is bound to magnesium and calcium to allow for a more gentle delivery of vitamin C.
  • Bioflavonoid blend: Includes quercetin and luteolin. These antioxidant-like plant compounds support vitamin C utilization. They also support the normal synthesis and release of histamine.

Why Optimal Vitamin C Plus Works

Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin. While many mammals and animals can synthesize their own, humans are missing the last enzyme in the gulonolactone oxidase pathway rendering us unable to make vitamin C. You must obtain this essential vitamin daily from diet or supplements.

Vitamin C is an essential cofactor for several enzyme reactions in the body. These include synthesizing collagen, carnitine, tyrosine, neurotransmitters, and regulating gene expression.

Vitamin C is one of the most foundational and well-studied nutrients for its antioxidant and immune health properties. As an antioxidant, vitamin C has potent reducing capabilities. By readily donating its electrons, vitamin C quenches free radicals such as hydroxyl and superoxide radicals, known to contribute to many health concerns. It also works with other antioxidants to create a stronger, synergistic antioxidative effect. For example, it has been shown that vitamin C enhances tocopherol (vitamin E) activity as a co-antioxidant.

As a cofactor, vitamin C also helps healthy histamine levels by supporting histamine metabolism, DAO production, and mast cell stabilization.

Vitamin C plays crucial roles in the histamine pathway as seen on the StrateGene® Report. The histamine N-methyltransferase (HNMT) enzyme converts histamine into N-methylhistamine, which can be toxic in high amounts. The monoamine oxidase enzymes, MAOA and MAOB, help to metabolize N-methylhistamine to reduce its levels. Vitamin C helps to increase MAOA and MAOB enzyme activity. This further supports the breakdown of histamine and its byproducts.

Histamine from foods and microbes needs to be broken down by the diamine oxidase (DAO) enzyme. Vitamin C plays a key role in allowing this process to happen. Further, vitamin C inhibits histidine decarboxylase, the enzyme that forms histamine from histidine. These key roles in histamine metabolism are supported by vitamin C.

The histamine pathway and many others can be explored in the StrateGene® Report.

Optimal Vitamin C Plus provides a bioavailable, buffered form of vitamin C as ascorbic acid, calcium ascorbate, and magnesium ascorbate. Vitamin C in the buffered form is less acidic and can reduce stomach upset from ascorbic acid. This can allow people with sensitive stomachs to tolerate higher doses of vitamin C.

Optimal Vitamin C Plus features a synergistic bioflavonoid blend of quercetin and luteolin. Bioflavonoids (flavonoids) are a type of compound synthesized by plants. They are thought to contribute to some of the health benefits of a plant-rich diet. Bioflavonoids support healthy inflammation responses, respiratory function, cellular health, and cellular communication. They also help enhance vitamin C’s action while providing synergistic antioxidant benefits.

Optimal Vitamin C Plus supports optimal vitamin C utilization. This heightens vitamin C’s ability to support healthy oxidative stress responses, antioxidant function, histamine balance, mast cell stability, and so much more.

How to Enhance Optimal Vitamin C Plus


Consider Pulsing

Dr. Ben Lynch recommends using certain dietary supplements based on your need for them. Start with a partial serving and increase slowly over time to the full serving, only if needed. When you start feeling good, consider reducing the serving size, skipping days, or pausing supplementation. Then take again when you feel you need it (stressful day, traveling, chemical exposure, etc.), hence "pulsing." Work with your qualified healthcare practitioner to determine what's best for you.
