Key Benefits

• Supports your immune system with vitamin C.

• Helps maintain healthy skin, bones, and gums through normal collagen formation.

• Protects cells from oxidative stress.

• Contributes to reducing tiredness and fatigue.

Start your day with Thorne’s Ascorbic Acid—your daily source of vitamin C. This essential nutrient supports your immune system, helping you feel ready for whatever life brings. Vitamin C also plays a key role in normal collagen formation, which is important for the health of your skin, bones, cartilage, gums, teeth, and blood vessels. It helps protect your cells from oxidative stress and contributes to reducing tiredness and fatigue, so you can keep up with your busy routine. Plus, vitamin C increases iron absorption, supporting your body’s daily needs.

Because your body can’t make vitamin C on its own, a daily supplement can help you maintain optimal levels. Each capsule delivers a potent 1g (1000mg) dose of vitamin C as ascorbic acid—an easy way to support your wellbeing every day.

Thorne’s Ascorbic Acid has been third-party tested and certified to ensure both ingredient accuracy and product purity. This verification confirms it contains exactly what’s stated on the label and is free from harmful levels of contaminants such as heavy metals, pesticides, and microorganisms. By taking this supplement, you can support your immune health and antioxidant defences with confidence in its quality and safety.
