Description

Vitamin C (ascorbic acid) is a key antioxidant, protecting cells throughout the body from oxidative stress and free radical damage.

Because vitamin C is an essential vitamin that the body can’t produce, it must be obtained from diet or by supplementation for optimizing both immune function and antioxidant support.*

Vitamin C plays a key role in promoting skin health as it supports healthy collagen formation and cellular repair. Pairing vitamin C with essential minerals like calcium, magnesium, and potassium provides additional support for healthy bone structure and soft tissue formation.*

FAQs
Frequently asked question

Is High Potency Vitamin C worth buying if I already eat fruits and vegetables?

Even with a healthy diet, most people don't consistently reach optimal vitamin C levels. This supplement offers a concentrated, reliable dose daily, making it especially useful during high-stress periods, illness, or when fresh produce intake varies. The buffered powder form is also gentle on the stomach compared to standard ascorbic acid tablets, making it a practical upgrade for consistent immune and antioxidant support.

Can I return High Potency Vitamin C if it doesn't work for me?

Yes, we stand behind our products with a satisfaction guarantee. If you're not happy with your purchase, contact our customer support team to learn about our return policy and eligibility. We recommend trying the supplement consistently for a few weeks before evaluating results, as nutrient-based supplements typically take time to show noticeable benefits.

What does 'buffered' vitamin C mean and why does it matter?

Buffered vitamin C is ascorbic acid combined with minerals like calcium and magnesium to reduce its acidity. This makes it much gentler on the digestive system, minimizing the stomach discomfort some people experience with standard vitamin C supplements. It's an ideal option for those with sensitive stomachs or anyone taking higher doses regularly.

How does vitamin C support immune health?

Vitamin C supports immune function by stimulating the production and activity of white blood cells, which help the body fight infections. It also acts as a powerful antioxidant, protecting immune cells from oxidative damage. Since the body cannot produce vitamin C on its own, consistent supplementation helps maintain the steady levels needed for optimal immune defense.

Can vitamin C help with skin health?

Yes. Vitamin C plays a critical role in collagen synthesis, which keeps skin firm, smooth, and resilient. It also supports cellular repair and protects skin cells from free radical damage caused by UV exposure and environmental pollutants. Regular supplementation can contribute to a healthier, more youthful complexion over time when paired with a balanced diet.

How should I take High Potency Vitamin C powder and what is the recommended dose?

Mix the recommended serving of powder into water or your favorite beverage once daily, or as directed by your healthcare provider. Taking it with food can further reduce any potential digestive sensitivity. Avoid exceeding the suggested dose without professional guidance, as very high vitamin C intake may cause gastrointestinal discomfort in some individuals.
