Description

Although you might rely on vitamin C only during the winter months, this vitamin can support your overall health every day. Vitamin C has many roles in your body and is linked to impressive health benefits, including immune function, collagen formation, and supporting liver detoxification.*

Because vitamin C is an essential vitamin that the body can’t produce, it must be consumed in the daily diet or by supplementation.

Thorne’s Vitamin C is the highest dose of vitamin C you can get in any of Thorne’s encapsulated vitamin C products.

What are the main health benefits of taking Vitamin C 1,000 mg daily?

Vitamin C supports immune function, collagen formation, and liver detoxification. It's a powerful antioxidant that helps protect cells from oxidative stress. Since the body cannot produce vitamin C on its own, daily supplementation ensures you consistently meet your needs, especially when dietary intake falls short. Regular use may benefit skin health, energy metabolism, and overall wellness year-round, not just during cold and flu season.

Why can't the body produce its own vitamin C?

Humans lack the enzyme needed to synthesize vitamin C internally, making it an essential nutrient. This means it must come from food sources like citrus fruits, bell peppers, and broccoli, or through supplementation. Without adequate daily intake, the body cannot maintain the vitamin C levels needed to support immune defense, collagen production, and antioxidant protection.

How much Vitamin C should I take per day?

The recommended dietary allowance for adults is 65–90 mg daily, but many health professionals suggest higher doses for optimal benefits. Thorne's 1,000 mg dose is a commonly used amount for those seeking more robust immune and antioxidant support. It's always a good idea to consult your healthcare provider to determine the right dosage based on your individual health needs.

Can I take Vitamin C 1,000 mg on an empty stomach?

Vitamin C can sometimes cause mild digestive discomfort when taken on an empty stomach, especially at higher doses. Taking it with food or a meal can help minimize any potential stomach sensitivity. If you experience irritation, splitting the dose throughout the day is another option. Most people tolerate 1,000 mg well when taken as part of their daily routine with meals.
