High Potency Vitamin C (Formerly Buffered C Powder)

Thorne High Potency Vitamin C is a buffered vitamin C powder that delivers 2.35 grams of vitamin C per scoop, with calcium, magnesium and potassium mineral-ascorbates that make it gentle on the stomach. It provides a higher amount of vitamin C per serving than Thorne’s capsule products.

Gentle, High-Potency Support from Thorne High Potency Vitamin C

Vitamin C is a key antioxidant that protects cells throughout the body from oxidative stress and free radical damage. Because the body cannot produce vitamin C, it must come from diet or supplementation. Thorne High Potency Vitamin C pairs ascorbic acid with buffering minerals so people with sensitive digestion can take higher amounts comfortably.

As a result, the formula supports healthy immune function, collagen formation and cellular energy production. The calcium and magnesium also provide additional support for bone structure and soft tissue health.

Who Thorne High Potency Vitamin C Is Best For

This powder suits people with sensitive digestive systems who want a higher daily vitamin C intake, plus anyone needing extra nutritional support after injury or surgery. It also suits those with higher vitamin C needs from stress, smoking, alcohol use or increased toxin exposure. Pair it with a nutrient-dense diet to support immune and antioxidant defences.
