Meta-C is advertised by the company that produces it as a dietary supplement. It is buffered form of vitamin C in the form of calcium ascorbate. Meta-C is intended to help people that don’t obtain enough vitamin C from their diet. It is used in the prevention or treatment of low levels of vitamin C.

Scientific studies have concluded that Vitamin C is an essential nutrient that the human body needs for many metabolic functions. The deficiency of vitamin C, which is required for the synthesis of collagen in the organism, is known to produce scurvy; a disease that manifests through malaise and lethargy, general weakness, neuropathy, emotional changes, anemia, gum disease, and skin hemorrhages. Vitamin C performs numerous physiological functions in the human body because it supports the synthesis of collagen, carnitine, and neurotransmitters.

The developer of this product is Nutribiotic. They are an American company that started their activity in 1980. They first worked on the development of various forms of Vitamin C and other nutrients and then continued their work in pioneering the use of grapefruit seed extract products in a wide variety of forms. At this moment they produce many protein supplements from rice and whey, as well as many forms of vitamin C supplements and body care products from various plant extracts including grapefruit seed extract.


1) Meta-C Quick Facts

Meta-C is a dietary supplement designed to improve the intake of vitamin C. It is destined not only for people with deficiency of vitamin C, but also for the prevention of low levels of this essential nutrient. According to the manufacturer, the serving size of 1 capsule of the formula provides 500 mg of vitamin C. It delivers 833% of the vitamin C daily value and 6% of the calcium daily value. The formula developed by Nutribiotic is advertised as having higher solubility and bioavailability due to the 6.2 pH which is close to that of the human blood (7.35 to 7.45)

Vitamin C is known to help in the support of the immune system by being a highly effective antioxidant. It lessens oxidative stress which is thought to cause or exacerbate the symptoms of many diseases such as cancer, Parkinson’s disease, Alzheimer’s disease, atherosclerosis, heart failure, myocardial infarction, Schizophrenia, bipolar disorder, vitiligo, autism, etc.

Meta-C is not meant to heal or diminish the symptomps of these diseases, but it can improve the immune system, therefore it helps the body prevent theiroccurrence.


2) What Are Meta-C Ingredients?

Meta-C includes the following ingredients: Meta-C calcium ascorbate, lemon bioflavonoid complex, magnesium stearate (vegetable lubricant), silicon dioxide (flowing agent), and gelatin (capsule).

Health Benefits

3) Meta-C Health Benefits

  • Vitamin C is essential for normal body functions
  • It is a fast way to improve the immune system


4) Meta-C Product Warnings

  • There are few online reviews for Meta-C
  • It has a high price in comparison to other brands on the market


5) Meta-C Serving Size

People that smoke tobacco, women that are pregnant, or people under stress, usually don’t acquire enough vitamin C through a normal diet, therefore the intake of vitamin C for these types of individuals should be increased through dietary supplements.

Bottom Line

6) The Bottom Line – “Does it Work?”

The manufacturer claims that Meta-C is an unique formula of buffered vitamin C which is absorbed faster by the body, although no proof is brought upfront to sustain their claims. It is also advertised as containing antioxidant bioflavonoids from lemon which boosts the antioxidant properties of vitamin C. Due to the lack of evidence to support the manufacturer’s claims, and the low number of online reviews regarding this product we cannot compare it to other brands on the market regarding its efficiency. The ingredients posted online by the manufacture assure us that this dietary supplement can provide the necessary intake of vitamin C for an adult.

Nutribiotic recommends this product as a dietary supplement to be consumed in a dosage of one capsule per day, but also advise to consult a licensed healthcare professional regarding the necessary intake of Meta-C.

I’ve tried many different forms of vitamin C, and I’m convinced that Meta-C is the best, especially if you want to take larger amounts. I’ve had chronic joint pain problems clear up quickly and permanently with a high enough dosage.
