Product Details

What is Vitamin C (Ascorbic Acid)?

Ascorbic acid is a water-soluble form of vitamin C that is of paramount importance to life. In 1937, the Nobel Prize for Medicine was awarded to Albert Szent-Györgyi (Wikipedia) for his studies of its biological functions: vitamin C supports numerous body functions including the immune system. Despite its importance, the body does not manufacture vitamin C and it is water-soluble. As a result, vitamin C is not stored in the body and must be consistently replenished by consuming fresh foods or taking supplements. All fruits and vegetables contain some amount of vitamin C. Rich sources of vitamin C include citrus fruits, sweet peppers, berries, tomatoes, broccoli, leafy greens, potatoes, and cantaloupe.

Among common nutrients and biochemicals, vitamin C is probably the most popular. Once ingested, vitamin C is readily absorbed by the intestines and continues its transport through the watery components of the human body, helping to build collagen protein and doubling as an antioxidant along the way. Ascorbic acid, together with sodium, potassium, and calcium salts, are typically used as antioxidant food additives. Commercial vitamin C is often a combination of ascorbic acid, Sodium Ascorbate and/or other ascorbates such as Calcium Ascorbate and Ascorbyl Palmitate.

Vitamin C has multiple functions as both a coenzyme and cofactor. Vitamin C is responsible for helping to build and maintain our tissues and strengthen our immune system. It is also essential for the oxidation of phenylalanine and tyrosine, and the conversion of folacin to tetrahydrofolic acid. Vitamin C is one of many antioxidants that help block damage caused by free radicals, byproducts of our bodies transforming food into energy. Vitamin C neutralizes potentially harmful reactions in the watery parts of the body, such as blood and fluid both inside and surrounding cells.

Ascorbic acid is required for collagen synthesis and plays a structural role in bone, cartilage, and teeth. As a participant in the hydroxylation of proline, vitamin C is needed for the production of collagen, a protein substance that all fibrous tissue integrity depends on. These fibers are found throughout the body, providing a firm but flexible structure. Collagen is the "glue" that strengthens many parts of the body like the muscles and blood vessels. Vitamin C can help the body repair damaged tissue, maintain healthy collagen, and promote healthy teeth and bones. Together with flavonoids, polyphenolics, and water-insoluble compounds (such as Vitamin E), l-ascorbic acid helps other antioxidants become more effective and successful in their work.

Is this the bioactive form L-Ascorbic Acid?

The Bioactive form of Ascorbic acid is the L- form and is the only one currently offered at In most cases when you see a product labeled as “Ascorbic acid” it is likely the L- form as the D- form and the racemic DL- form has not been as commercially available for some time.

Bioavailability, Mixing, and Solubility of Vitamin C

L-ascorbic acid is a bioavailable form of ascorbic acid and is frequently added to commercially produced foods and beverages. This product is a white or yellowish-white fine granular powder that dissolves quickly in water and has a sour taste. It can be mixed with water or fruit juices or drinks. It is normal for ascorbic acid crystals to discolor slightly upon exposure to air and moisture.

For people who are sensitive to sour products or for those who do not like the sour taste of ascorbic acid supplements, we suggest using ascorbic acid capsules.

Please note that ascorbic acid is a relatively fragile molecule and it may be lost from foods during preparation, cooking, and/or storage. Ascorbic acid is easily destroyed by oxidation, particularly in the presence of heat and alkalinity.

Sodium Ascorbate Recipe

You will need:
#1:  One 8 ounce drinking glass
#2:  A set of kitchen measuring spoons
#3:  A spoon (for stirring)
#4:  PureBulk 100% Pure Ascorbic Acid Powder
#5:  Sodium Bicarbonate Powder (Arm & Hammer Baking Soda)
#6:  Approximately 2 to 3 fl oz warm to slightly hot drinking water

In a dry 8-ounce drinking glass place 5 g of Ascorbic Acid (one level teaspoon) and 2.5 g Baking Soda (1/2 level teaspoon). Add 2 fl oz warm to slightly hot drinking water. A violent reaction occurs generating (CO2) bubbles. Stir for 10 to 20 seconds or until bubbles slow and the solution turns clear. This reaction creates 5.62 grams of Sodium Ascorbate (NaA), 1.25 grams of Carbon Dioxide gas and 0.51 grams water. Consume within 10 minutes, as Sodium Ascorbate will react with oxygen in the air to lessen potency.

For children 3 to 12 years old, use half the adult serving amount, i.e. 1/2 level tsp Ascorbic Acid Powder and 1/4 level tsp Baking Soda. After stirring and the solution has turned clear, add 4 fl oz fruit juice.
