What does Vitamin C support in the body?

Vitamin C supports the immune system, collagen synthesis, brain, eyes, heart, and circulation. It also acts as a powerful antioxidant, helping neutralize free radicals and support overall organ health.*

What is Q-C ascorbic acid and where is it made?

Q-C (Quali-C) is a premium form of ascorbic acid manufactured in Scotland, renowned for its purity and reliability. It is non-GMO, gluten free, soy free, and vegan with no added fillers.

What's the daily dosage?

Mix 1 level scoop (1g / 1000mg) in 8 oz of fruit juice or beverage of your choice daily, preferably without food, or as recommended by a nutritionally informed physician.

Does it fully dissolve?
