NOW Foods Vitamin C Crystals, Pure Ascorbic Acid Powder, 454 g

Key Benefits of Vitamin C

Vitamin C is well known for its contribution to the normal function of the immune system. It also helps protect cells from oxidative stress through its antioxidant activity.* Research suggests that adequate intake supports immune health, particularly during periods of physical stress or seasonal challenges. Additionally, vitamin C is involved in collagen synthesis, which is important for maintaining healthy skin, blood vessels, and connective tissues.* Many people choose this powder form because it allows flexible dosing to suit personal needs.

What Is Vitamin C and Why Do You Need It?

Vitamin C is a water-soluble nutrient essential for the body, but it cannot be produced internally—it must come from diet or supplements. This pure ascorbic acid powder from NOW Foods provides a versatile and high-quality way to meet daily vitamin C requirements. It is valued for its antioxidant properties, helping neutralise free radicals generated during normal metabolism and from environmental stressors.* Each bottle contains 454 grams of pharmaceutical-grade vitamin C crystals, offering a convenient and cost-effective option for those who prefer customising their dose or mixing the powder into drinks. This product is ideal for individuals seeking a basic, no-additive supplement for overall wellness.

Why Choose Pure Ascorbic Acid Powder?

Pure ascorbic acid is the simplest and most common form of vitamin C. It is highly concentrated, so a small amount delivers a significant dose. This powder contains no binders, fillers, or artificial ingredients, making it excellent for those with dietary restrictions or sensitivities. NOW Foods ensures this product is non-GMO, vegan, kosher, and free from gluten, soy, nuts, dairy, and eggs. It is manufactured in facilities following Good Manufacturing Practises (GMP) with third-party quality assurance. The crystalline form dissolves easily in water, juice, or smoothies, with a tart, citrus-like flavour—a practicable alternative for those who dislike tablets or capsules.

How to Use Vitamin C Crystals

The right serving size depends on individual health goals. As a general guide, one level teaspoon (approximately 4 grams) provides about 4,000 mg of vitamin C. Because this is a high-dose option, it is advisable to start with a smaller amount—such as a quarter or half teaspoon—and gradually increase as tolerated. Mix the powder into cool or lukewarm liquids; avoid very hot beverages as heat may degrade vitamin C over time. Since vitamin C is water soluble, excess is usually excreted, but high doses may cause digestive discomfort for some people. Spreading intake throughout the day can minimise any issues. This product contains no added sugar, artificial colours, or preservatives, making it suitable for a clean diet.

Recommended Dosage and Safety

The recommended dietary allowance (RDA) for vitamin C varies by age, sex, and life stage. For most adults, the RDA ranges from 75 to 120 mg per day, whilst higher intakes are commonly used for targeted support or as directed by a health care professional. Because this powder is potent, careful measurement is advised. A typical supplement dose is between 250 mg and 1,000 mg daily unless otherwise recommended. Vitamin C is generally well tolerated. It can increase absorption of non-heme iron, so those with certain iron-related conditions should consult a health care provider before use. Pregnant or nursing women, or individuals with underlying health conditions, should also seek medical advice. This product is intended for adults only. Keep out of reach of children. Store in a cool, dry place after opening.

This product is a food supplement and should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended dose unless advised by a health care professional. Food supplements should be stored out of reach of young children.
