What is vitamin C?

Vitamin C is also known as ascorbic acid, L-ascorbic acid, or ascorbate. It is an essential vitamin that’s naturally synthesized in the livers of most mammals from blood sugar (glucose) as needed.

However, humans, higher primates, Guinea pigs, and some fruit-eating bats lack an enzyme required for this internal production of the vitamin, so we must get it in foods every day, and constantly recycle it in the body using other antioxidants and free radical fighters.

What is calcium ascorbate?

Calcium ascorbate is a buffered salt (mineral compound) form of the water-soluble antioxidant vitamin C (ascorbic acid).* Calcium is reacted with ascorbic acid to buffer the acidic nature of this vitamin, making it gentler for those who have a sensitive gastrointestinal tract.

The pH of this buffered mineral ascorbate is approximately 6.8~7.4, as compared to ascorbic acid that is about a pH of 2.5. Calcium Ascorbate provides approximately 10% elemental calcium and 90% vitamin C, by weight.

What does vitamin C do in our bodies?

Ascorbate (vitamin C) is a reducing sugar (has a reactive ene-diol structure) that is involved in biochemical processes, such as hydroxylation of proline and lysine utilized in the formation of collagen and healthy connective tissue.* Ascorbate is involved in many other vital functions such as the mobilization of iron, competence of the immune system, and as an antioxidant for scavenging of reactive free radicals.*

What is the function of citrus bioflavonoids that are in some of your vitamin C formulas?

Bioflavonoids are biologically active flavonoid compounds found throughout the entire plant kingdom. Since the discovery of flavonoids in 1936, over 4,000 different types have been characterized. Though there are several forms of bioflavonoids in the citrus complex, the predominant one is Hesperidin. These flavonoids exhibit beneficial effects on capillary permeability and therefore support healthy blood flow.* They work synergistically with vitamin C.*

Why are there color variations in your different vitamin C products, and are they safe to take?

Most natural vitamin C products vary in color from batch-to-batch and bottle-to-bottle. There are normally variations in the color of the raw material used during manufacturing. This is due to natural color variations in the source of the vitamin C. Generally, you will find Vitamin C supplements to range in color from off-white to light tan to light gray. Additional color variation can be introduced by other ingredients in a formula, such as citrus bioflavonoids, etc.

Over the course of the shelf-life of a vitamin C supplement, oxidation can cause a slight change in color, so you may find the vitamin C-1000 you bought has changed to a darker color six months later. This is a normal occurrence, and the product is safe to use at least until the “Best By” date, and often beyond.

NOW® is generally conservative with our usage dates, so a vitamin C product should still meet label claims and is likely safe after that date, but may not be as effective due to oxidation lowering the strength of the vitamin over time. If the product has significantly darkened and/or appears to have been exposed to moisture, those are signs that the product may no longer be safe and effective.

Can I pour the powder in NOW® Vitamin C capsules into a liquid instead of swallowing the capsule?

Many people don’t want to or cannot swallow capsules, tablets, or softgels, for various reasons. Encapsulated vitamin C products from NOW® can be opened and mixed into a liquid for consumption. Juice or water is recommended if you choose this method. However, taking vitamin C with water on an empty stomach is the usual method of ingestion. Before you try this, please be aware that we carry several powdered forms of vitamin C products for your convenience.

Why Take Vitamin C?

Vitamin C supports the immune system and is involved in tissue growth and repair due to its role in the formation of collagen, the body’s main structural protein.

Versatile Vitamin C

Also known as ascorbate and ascorbic acid, vitamin C is a water-soluble vitamin that’s absolutely essential for our survival. A well-known antioxidant nutrient, vitamin C supports the immune system and is involved in tissue growth and repair due to its role in the formation of collagen, the body’s main structural protein.*

Vitamin C is an electron donor, which is important for the synthesis of enzymes, and it’s a cofactor in the production of numerous essential biochemicals. Vitamin C is also involved in the synthesis of the amino acid carnitine, as well as various neurotransmitters.*

There are various forms of vitamin C available, so you may be wondering what the best form of vitamin C is, or whether or not it even makes a difference. Because vitamin C is acidic you’ll often find vitamin C supplements that include mineral ascorbates, which are mineral salts of ascorbic acid that are buffered and therefore, less acidic.

There are also a number of natural substances that support and even enhance the absorption, bioavailability, and benefits of vitamin C, including rutin, rose hips, and other natural sources of bioflavonoids.

The best form of vitamin C for you will depend on your lifestyle and health goals. Check with your health care provider or a certified nutritionist if you’re not sure what form is right for you.
