Immune support, collagen for skin that looks its best, and antioxidant protection, from the cleanest vitamin C we could find.
- Immune support. Vitamin C helps your immune system work normally, and your body can't make its own.
- Collagen and skin. Vitamin C is needed to make collagen for skin, gums and connective tissue.
- Antioxidant protection. It helps protect cells from oxidative stress and helps recycle vitamin E.
- Energy and iron. It plays a part in normal energy metabolism and fatigue, and helps you absorb iron from plant foods.
A good fit for bioenergetic, low-toxin living. Vitamin C works alongside your cells' energy-making and protects the vitamin E that guards your fats. Pure ascorbic acid with nothing else in the bag keeps it clean.
Why this vitamin C:
- Not made in China. Most of the world's vitamin C is. Quali-C® is made by dsm-firmenich in Dalry, Scotland, which the maker says is the only vitamin C production site in the Western world. They've made vitamin C there for over 40 years.
- Pharmaceutical standards. Quali-C® meets USP, FCC and European Pharmacopoeia standards.
- Non-GMO start. The maker's process starts from fermented non-GMO European wheat glucose.
- One ingredient. Ascorbic acid. No fillers, flow agents or flavors.
- Mixes easily. Ultrafine powder that dissolves in water or juice, with a bright, tart taste.
- Powder for flexible amounts. Weigh it on a precision digital scale for accuracy.
Customers say it best: "This ultrafine European made vitamin c will dissolve completely in water." And: "This is the only vit C powder that I fully trust."
Quali-C® is a dsm-firmenich ingredient; we're an authorized seller. 60-day no hassle returns.
Start low. Begin with 500 mg a day in water or juice. Weigh it on a precision digital scale for accuracy.
Raise slowly. If you want more, add a little at a time over several days and split it through the day.
Signs to ease off. If stools get loose or your stomach gurgles, take less. Talk to your healthcare provider about higher amounts.
Iron note. Vitamin C helps you absorb iron, so if you watch your iron, take it away from iron-rich meals.
Rinse your mouth with water after taking it straight; it's acidic.

Vitamin C: what the research shows
Vitamin C is an essential, water-soluble vitamin. Humans can't make it, so it has to come from food or supplements. These studies cover vitamin C in general, not this exact product.
Immune function

Skin and collagen

Skin holds high levels of vitamin C, which it uses to make collagen and protect itself from oxidative stress.

Bioenergetic & low-toxin perspective
Ray Peat saw vitamin C as a protective antioxidant that works with vitamin E, while staying mindful of iron.
"Antioxidants: Vitamin E and vitamin C are known as antioxidants, because they stop the harmful free-radical chain reactions which often involve oxygen, but they do not inhibit normal oxidation processes in cells." — Ray Peat, "Iron's Dangers" (https://raypeat.com/articles/articles/iron-dangers.shtml)
"Vitamin C stimulates the absorption of iron, so it might be a good idea to avoid drinking orange juice at the same meal with iron-rich foods." — Ray Peat, "Iron's Dangers" (same URL)
A study Peat cited, quoted in his "Immunodeficiency, dioxins, stress, and the hormones" article (https://raypeat.com/articles/articles/immunodeficiency.shtml): Bendich A (1988). Vitamin E and immune functions. Basic Life Sci 49:615-20. PMID 3074789. Its abstract, as quoted there: "High levels of vitamin C can protect tissue levels of vitamin E and may indirectly contribute to the immunoenhancement by vitamin E."
