Ascorbic Acid: A Foundational High-Potency Vitamin C

Thorne’s Ascorbic Acid provides a high-potency, 1-gram dose of Vitamin C, one of the most essential nutrients for foundational health. As a powerful water-soluble antioxidant, Vitamin C is crucial for supporting a robust immune response, promoting the synthesis of collagen, and protecting the body from cellular stress. This pure, simple formula is an excellent choice for individuals seeking to bolster their immune defenses, support skin and connective tissue health, and enhance their overall antioxidant network. It is also NSF Certified for Sport®, ensuring its purity and safety.*

How It Works: The Body’s Master Antioxidant

Vitamin C is a true workhorse nutrient, participating in hundreds of processes that are vital for keeping you healthy and resilient.

Support for a Resilient Immune System
One of Vitamin C’s most well-known roles is in supporting the immune system. It promotes the production and function of white blood cells, which are the body’s primary line of defense. Because physical and emotional stress can deplete Vitamin C levels, a consistent intake is crucial for maintaining immune readiness.*

Essential for Collagen and Wound Healing
The body requires Vitamin C to produce collagen, the primary structural protein found in skin, tendons, ligaments, and blood vessels. Therefore, adequate Vitamin C is essential for maintaining healthy skin elasticity and promoting the efficient healing of wounds. In addition, it functions as a master antioxidant, helping to neutralize damaging free radicals and regenerate other antioxidants in the body, like Vitamin E.
