Product Information
Vitamin C powder immune and antioxidant supplement for sensitive stomachs
Thorne's Buffered C Powder is a vitamin C supplement, formulated to provide the benefits of this powerful vitamin without causing stomach discomfort. Vitamin C is widely known for its essential role in strengthening the immune system, providing antioxidant protection, and producing collagen, which helps maintain healthy skin, bones, and joints.
The form of vitamin C in Buffered C Powder reduces the acidity of traditional vitamin C, making it gentler on the stomach, ideal for people with gastric sensitivities. Additionally, vitamin C is a potent antioxidant that helps neutralize free radicals in the body, promoting cellular health and protecting against oxidative damage.
This supplement is especially useful for strengthening the immune system, boosting energy, and promoting rapid recovery after illnesses or intense physical activities.
✅ Immune system support: Vitamin C can help strengthen the body's natural defenses, reducing the risk of infections.

FAQs
It is a powdered supplement with buffered vitamin C (2,350 mg per serving), calcium ascorbate (350 mg), magnesium ascorbate (350 mg), and potassium ascorbate (99 mg), with no excipients, gluten-free, soy-free, and lactose-free. The buffered form may be gentler on the stomach than pure ascorbic acid. It can support the immune system, antioxidant protection, and normal collagen formation.
Conventional vitamin C (pure ascorbic acid) is an acidic form that can cause gastric discomfort at high doses. Buffered vitamin C combines ascorbic acid with minerals (calcium, magnesium, potassium) to form ascorbate salts, which are less acidic and may be better tolerated by the stomach, especially at higher doses.
Yes. The buffered form was developed precisely for those who want to support immunity and antioxidant protection with higher doses of vitamin C, but experience gastric discomfort with conventional forms. The presence of mineral ascorbates can make the formula gentler on the stomach.
