THORNE - High Potency Vitamin C - Ascorbic Acid with Calcium, Magnesium & Potassium - 42 Servings

Key Benefits of Vitamin C

Vitamin C is best known for its role in immune support. It helps stimulate white blood cell production and function, aiding your body's natural defences. As a powerful antioxidant, it also neutralizes free radicals, protecting cells from oxidative stress. Additionally, vitamin C is essential for collagen synthesis, which maintains skin elasticity, wound healing, and joint health. THORNE's formula includes buffering minerals—calcium, magnesium, and potassium—to support bone health, nerve function, and muscle contraction while reducing stomach acidity. This makes it easy to take higher doses without discomfort. Health Canada permits the claim: 'Helps maintain immune function.'

Types of Vitamin C Supplements

Vitamin C supplements come in various forms. Ascorbic acid is common but can be acidic and cause digestive distress. Buffered vitamin C, like THORNE's, combines ascorbic acid with alkaline minerals (calcium, magnesium, potassium) to neutralize acidity, offering a gentler experience. Other forms include sodium ascorbate (higher sodium), liposomal vitamin C (enhanced absorption), and whole-food sources like acerola cherry. THORNE's mineral ascorbate blend delivers high potency with added nutritional value and excellent tolerability.

What Is Vitamin C and Why Do You Need It?

Vitamin C is a water-soluble essential nutrient that your body cannot produce. It must come from diet or supplements. THORNE's High Potency Vitamin C provides 1,000 mg of ascorbic acid per serving (two capsules), combined with calcium, magnesium, and potassium for enhanced absorption and minimized stomach upset. This formula supports immune function, promotes collagen for healthy skin and connective tissues, and provides antioxidant protection. Whether for daily wellness or targeted support, this third-party certified supplement offers a reliable, high-quality option.

How to Choose the Best Vitamin C Supplement

When choosing a vitamin C supplement, consider dosage, form, and additives. THORNE's product provides 1,000 mg per serving—potent yet manageable. The buffered form is ideal for sensitive stomachs. Look for third-party certification to ensure purity and potency. This supplement is gluten-free, dairy-free, and soy-free, suitable for many with dietary restrictions. THORNE is trusted by professional sports teams and healthcare practitioners, reflecting commitment to quality.

Recommended Dosage and Safety

The suggested use is two capsules daily, providing 42 servings per bottle. Vitamin C is water-soluble, but doses over 2,000 mg daily may cause diarrhea or cramping. Start with the recommended serving. Women who are pregnant or nursing, individuals with kidney disorders, or those on medication should consult a healthcare professional. Vitamin C can increase iron absorption; use caution if you have hemochromatosis or iron overload. Store in a cool, dry place, out of reach of children.

Frequently Asked Questions

Can I take THORNE Vitamin C on an empty stomach?
The buffered form is gentle, but if you have a sensitive stomach, take with food.

Is this product suitable for vegetarians?
Yes, the capsules are vegetarian-friendly, made from hypromellose.

How does it compare to liposomal vitamin C?
Liposomal vitamin C uses lipid encapsulation for higher absorption per milligram. THORNE's mineral ascorbate offers a convenient, cost-effective alternative with good bioavailability and added minerals.

Can I split the dose throughout the day?
Yes, splitting the two capsules can improve absorption and reduce any discomfort. Vitamin C has a short half-life, so smaller, frequent doses maintain steady levels.

Is this product third-party tested?
Yes, it is third-party certified for purity and potency, ensuring what's on the label is accurate.

Risk information: High doses may cause digestive upset. Consult your healthcare practitioner before use if you are pregnant, nursing, or have a medical condition. Always read and follow the label.
