dUSANA Proflavanol C200 Reflects a Broader Approach to Antioxidant Supplementation

Antioxidant supplements have long included familiar nutrients such as vitamin C, but newer formulations increasingly combine vitamins with plant-derived compounds. That approach is evident in USANA ProflavanolC200, a supplement built around vitamin C and grape seed extract.

The formulation provides an example of how antioxidant products are moving toward combinations of nutrients and phytonutrients, giving consumers another factor to consider when comparing products in an already crowded category.

Vitamin C Meets Grape Seed Extract

According to USANA’s product information, a two-tablet serving of Proflavanol C200 provides 600 milligrams of vitamin C and 400 milligrams of grape seed extract. The vitamin C comes from a blend of potassium, magnesium, zinc and calcium ascorbates.

Vitamin C is an essential nutrient with established roles in normal immune function and collagen formation. It also functions as an antioxidant, helping protect cells from oxidative damage.

Grape seed extract brings a different group of plant compounds to the formulation. Grape seeds contain polyphenols, including proanthocyanidins, that have attracted scientific attention for their antioxidant properties.

Combining the two creates a formulation that draws on both an essential vitamin and plant-derived compounds.

Proflavanol Has Been Part of a Wider Product Update

The product also fits within a larger update to USANA’s nutritional portfolio. In 2025, the company announced reformulations across several established products, including its Proflavanol line.

USANA said its updated Proflavanol formulation was being expanded with a broader selection of flavonoids, including hesperidin, quercetin, green tea extract and bilberry extract. The company positioned the change as part of a larger effort to update existing nutritional products alongside the introduction of new ones.

That development reflects a wider trend in supplement formulation: pairing established nutrients with a more diverse range of plant compounds.

Understanding Antioxidant Support

Antioxidants are often discussed as a single category, but the term covers numerous substances that function differently in the body. Some are vitamins produced or obtained through diet, while others are compounds naturally present in fruits, vegetables and other plants.

That distinction makes the ingredient panel particularly important when consumers compare antioxidant supplements.

Amounts matter as well. Looking beyond the product name to examine serving size, vitamin content and specific botanical extracts provides a clearer picture of what a supplement actually delivers.

Where Supplement Quality Fits In

USANA’s product documentation for Proflavanol C200 states that the supplement is laboratory tested and meets applicable U.S. Pharmacopeia specifications for uniformity, potency and disintegration. The label also advises consumers who are pregnant, nursing, taking prescription drugs or managing a medical condition to consult a physician before use.

Those details provide useful context because antioxidant supplementation should be considered alongside diet, lifestyle and individual nutritional needs.

Proflavanol C200 ultimately illustrates the increasing complexity of the antioxidant category. Products are combining familiar nutrients such as vitamin C with concentrated sources of plant compounds, making ingredient transparency and formulation details increasingly important for consumers trying to understand what distinguishes one antioxidant supplement from another.

Conclusion

Proflavanol C200 ultimately illustrates how the antioxidant supplement category is evolving beyond single-nutrient formulations. By combining vitamin C with grape seed extract and other plant-derived compounds, the product reflects a broader interest in bringing multiple sources of antioxidant compounds into one formulation. For consumers, understanding the specific ingredients, serving sizes, quality standards, and intended use can make it easier to compare products and make informed choices. As supplement formulations continue to develop, transparency around ingredients and evidence-based information will remain important when evaluating antioxidant products as part of an overall approach to nutrition and wellness.
