Full Spectrum Vitamin C is Dr. Cabral's formula that combines vitamin C with various bioflavonoids to mirror the way vitamin C is found in nature.



Full Spectrum Vitamin C has been harvested from multiple sources rich in vitamin C and it enhances immune function while providing support for healthy collagen synthesis and connective tissue. It also supports normal levels of inflammation throughout the body. Each capsule of Full Spectrum Vitamin C provides a full 400 mg vitamin C, 100 mg acerola extract, 70 mg quercetin, 50 mg hesperidin, 50 mg hibiscus and 50 mg rutin in an easy-to-take capsule form.


While most mammals can synthesize vitamin C, humans lack the enzyme required to synthesize vitamin C from glucose and, must obtain the vitamin from their diet. The primary function of vitamin C is to help manufacture collagen, the main structural protein of connective tissues in the human body. Still, vitamin C is crucial in a variety of biological functions, particularly the immune system, skin, blood vessels, arteries and gums. It is an important antioxidant, providing protection from free radicals and the oxidative stress resulting from normal cellular function.

In addition, vitamin C is important in brain health, where it supports neurotransmitter (brain chemical) synthesis, normal stress hormone production and serves as a cofactor for several metabolic enzymes, including hydroxylation reactions that are essential for collagen formation.1-4


While true deficiency in vitamin C is rare (the most severe form of deficiency is known as scurvy), evidence suggests that many people may have low levels of vitamin C, especially those under high amounts of stress and low dietary fruit and vegetable intake. Signs of deficiency include dry and splitting hair, bleeding gums, dry or scaly skin and easy bruising. Those taking NSAIDS, aluminum-based antacids, oral contraceptives, barbiturates, tetracycline and Coumadin are more susceptible to depletion of vitamin C.5 Immune Supportð Vitamin C has long been recognized for its role in supporting the immune system, specifically T cells, which absorb and concentrate vitamin C.2,6,7


A randomized, double-blind, placebo-controlled study (1,000 subjects taking 1,000 mg of vitamin C per day) revealed that the group given vitamin C could consistently maintain a healthy immune response.8 Supplementation with vitamin C has also been shown to support immune response to seasonal challenges by supporting natural killer cells, lymphocyte proliferation, chemotaxis and delayed-type hypersensitivity.9 Inflammatory Balance† Vitamin C plays a key role in maintaining normal inflammatory balance.


In a randomized crossover study (20 subjects, aged 21-29 years, who randomly consumed two glasses (250 mL each) of either a vitamin C-rich apple juice or a polyphenolrich juice), numerous cardiometabolic markers were found to be maintained in the healthy range, as was antioxidant status.10 Supplementation with vitamin C has been shown to support microbial balance in the gastric mucosa by promoting an environment where healthy microflora can thrive, increase tissue antioxidant status and enhance the absorption of key nutrients.11 High-dose vitamin C has also been shown to balance cytokines and help maintain healthy C-reactive protein levels in 75% of patients assessed.[12] A cross-sectional study of lean and obese men aged 21± for three years found that higher vitamin C status was associated with better maintenance of normal inflammatory balance and blood vessel health.[13]


Dr. Cabral's Full Spectrum Vitamin C contains a group of powerful plant-based antioxidants called bioflavonoids. Bioflavonoids are a group of plant pigments that provide the colors of many fruits and flowers. Flavonoid intake is associated with cardiovascular health and microbial balance.[14,15] Bioflavonoids are used to support connective tissue and joint comfort[16,17,18] as well as respiratory and eye health. Citrus bioflavonoids have also been shown to cross the blood-brain barrier, impart neuroprotective effects[19] and promote healthy cell growth, detoxification enzymes, vasodilation and healthy platelet function.[20] Quercetin, a flavonoid found in a variety of herbs, vegetables and fruits, is an antioxidant that inhibits inducible ICAM-1 expression, an important pathway for maintaining normal inflammatory balance.[21]It has also been shown to support epithelial barrier function in the intestines[22], to stabilize mast cells by releasing cytoprotective factors and to promote the balanced release of inflammatory mediators from mast cells.[23] Rutin and hesperidin complex are strong antioxidants, which increase intracellular levels of vitamin C and offer similar benefits to quercetin.

Family First

Every product on this website was formulated with the mindset that my family and I would be using each nutritional supplement.

When you go into a product formulation knowing that your own family and children will use these products it ensures there will never be any compromise…

Plus, I want only the best for my online community and private practice clients. And, since people come to me for results after failing many times in the past, I have to know that every one of these products are truly the best of the best and will help people on their healing journey…


Functional Medicine Formulations

It’s important to understand that not all nutritional supplements are created equal.

For example, in a Functional Medicine practice only methylated or highly bio-available vitamins and minerals will be used in order to make it easy for the body to utilize.

Not only do these formula get better results, but they do not build up as toxins in the body or simply get excreted in the urine like most cheaper forms… 


Zero Compromise Policy

I made a promise to myself when I first started formulating the Equilibrium Nutrition line that I would not compromise on quality…

Even if a product cost me a few more dollars, I would not take any shortcuts in order to make a product for less.

This has enabled Equilibrium to set itself apart even in the Functional Medicine community as a leader in the best ingredients used.


GMP Certified

Besides never compromising on using the highest quality ingredients available when formulating our nutritional supplements, I make sure that each batch is 3rd Party tested for contaminants like:

  • Heavy metals
  • Mold
  • Bacteria
  • Impurities
  • Standard dosages

This then allows me to be confident when consuming these products myself and knowing that the dosages are what is stated on the bottle.

Again, this leads to better user results and happier customers and wellness clients!


Consistency & Freshness

Another way in which the Equilibrium Nutrition supplement line sets itself apart as the leader in the industry is by always producing fresh orders every couple of months.

Our products do not sit in warehouses for over a year…

Instead we maintain freshness with smaller continuous batch orders along with climate controlled fulfillment centers.

This guarantees purity, freshness, and taste.

This is a difference you can both see and taste with every bottle!

At Equilibrium Nutrition we strive to provide the fastest and most convenient shipping available!
