Pros
- High-quality, third-party certified ingredients
- Includes beneficial citrus bioflavonoids for added antioxidant power
- Trusted by healthcare professionals and athletes
- Supports immune, skin, and detox health in one formula
- Easy-to-swallow capsules with no artificial additives
Cons

THORNE Vitamin C 500 mg with Citrus Bioflavonoids is a premium supplement designed for health-conscious individuals who demand purity and effectiveness. This formula pairs vitamin C with natural citrus bioflavonoids, which are plant compounds that enhance vitamin C's absorption and antioxidant activity. It is particularly suited for those looking to support their immune system, maintain healthy skin, or aid their body's natural detoxification processes.
In terms of performance, this product delivers on its promises. The inclusion of citrus bioflavonoids from oranges provides a synergistic boost, offering better cellular protection against free radicals than vitamin C alone. Users report noticeable improvements in skin texture and resilience, thanks to the collagen-boosting properties. Additionally, the detox support is a standout feature, as it helps increase glutathione levels, a master antioxidant that plays a key role in liver health and toxin elimination.
The design and build quality are typical of THORNE's standards: a clean, amber bottle that protects the contents from light degradation, and capsules that are free from unnecessary fillers or artificial ingredients. The capsules are of moderate size, though some may find them slightly large, but they are generally easy to swallow with water. The product is also third-party certified, which adds an extra layer of trust for consumers who are cautious about supplement quality.
One potential drawback is the price, which is higher than many basic vitamin C options on the market. However, given the added bioflavonoid complex and the brand's reputation for clinical-grade supplements, many will find the cost justified. Another minor consideration is that each capsule provides 500 mg, so those needing a higher daily dose may need to take multiple capsules, which could increase the overall cost.
Overall, THORNE Vitamin C 500 mg with Citrus Bioflavonoids is an excellent choice for anyone seeking a high-quality, multi-benefit vitamin C supplement. It offers robust immune support, promotes skin health, and aids detoxification, all in a trusted, third-party-tested formula. While it comes at a premium, the quality and efficacy make it a worthwhile investment for your health.
