Vitamin C Powder — Pure Ascorbic Acid

(L-Ascorbic Acid)

Pure L-ascorbic acid — Vitamin C — in convenient powder form. 100% pure ascorbic acid with no additives, fillers, or preservatives. Vitamin C is one of the most essential and well-studied nutrients in human nutrition — it is a water-soluble vitamin that the human body cannot synthesize on its own (unlike most mammals, humans lack the enzyme L-gulonolactone oxidase required for endogenous vitamin C synthesis) and must obtain entirely through diet or supplementation. The history of vitamin C is one of the most dramatic in nutritional science — the deficiency disease scurvy devastated sailors, soldiers, and populations throughout history, and the discovery that citrus fruits could prevent and cure scurvy (documented by the Scottish naval surgeon James Lind in his landmark 1747 controlled trial — one of the first clinical trials in medical history) was one of the most important public health discoveries of the 18th century. Vitamin C was first isolated in 1928 by the Hungarian biochemist Albert Szent-Györgyi (who received the Nobel Prize in Physiology or Medicine in 1937 for this discovery) and was first synthesized in 1933 by the British chemist Walter Norman Haworth (who shared the 1937 Nobel Prize in Chemistry). The recommended daily intake (RDI) for vitamin C is 65–90 mg per day for adults, with a tolerable upper intake level (UL) of 2,000 mg per day.

L-Ascorbic acid (Vitamin C — C₆H₈O₆) is a six-carbon lactone with a molecular weight of 176.12 g/mol and one of the most potent water-soluble antioxidants known — it donates electrons to neutralize free radicals and reactive oxygen species, and it regenerates other antioxidants including vitamin E (alpha-tocopherol) from their oxidized forms. Vitamin C is an essential cofactor for numerous enzymatic reactions, most notably as a required cofactor for prolyl hydroxylase and lysyl hydroxylase — the enzymes responsible for the hydroxylation of proline and lysine residues in collagen biosynthesis, making vitamin C absolutely essential for the synthesis and maintenance of collagen, the most abundant protein in the human body. Vitamin C also serves as a cofactor for dopamine beta-hydroxylase (required for the synthesis of norepinephrine from dopamine), peptidylglycine alpha-amidating monooxygenase (required for the amidation of neuropeptides), and the enzymes required for the biosynthesis of carnitine. Vitamin C significantly enhances the absorption of non-heme iron (plant-based iron) by reducing ferric iron (Fe³⁺) to ferrous iron (Fe²⁺) in the gastrointestinal tract — a well-established nutritional interaction of significant practical importance for plant-based diets. 100% Pure L-Ascorbic Acid. No additives or preservatives. Available in Powder form.

How to Use

Beverages: Stir ¼–½ teaspoon (approximately 1,000–2,000 mg) into water, juice, or smoothies — the powder dissolves quickly and adds a pleasant tartness. Iron Absorption: Add to meals containing plant-based iron sources (legumes, leafy greens, fortified foods) to enhance non-heme iron absorption. Smoothies: Blend into fruit smoothies — pairs naturally with citrus, berry, and tropical flavors. Cooking Note: Vitamin C is heat-sensitive and degrades at high temperatures — add to foods after cooking for maximum potency. Topical: Vitamin C powder can be dissolved in water or serum bases for topical skin preparations — use at concentrations of 10–20% in a pH-adjusted base (pH 3.5) for stability.

Available in Powder (4 oz, 8 oz, 16 oz).

Consult your healthcare provider before use if you are pregnant, nursing, taking medications, or have a medical condition (particularly kidney disease or a history of kidney stones — high-dose vitamin C may increase oxalate excretion). High doses may cause gastrointestinal discomfort. Keep out of reach of children. Store in a cool, dry place away from light and moisture — ascorbic acid oxidizes rapidly when exposed to air, light, and heat.
