Frequently Asked Questions
This is Nature's Sunshine's vitamin C formula enhanced with natural citrus bioflavonoids for added antioxidant support. Each tablet delivers 500 mg of Vitamin C — 835% of the daily value — along with bioflavonoids from lemon, orange, and grapefruit, plus hesperidin, rutin, and rose hips extract. It's designed to provide well-rounded free radical protection.
Bioflavonoids are naturally occurring plant compounds found in citrus fruits that work synergistically with vitamin C to support its absorption and effectiveness. This formula includes 50 mg each of lemon, orange, and grapefruit bioflavonoids, along with hesperidin complex and rutin — all of which may help promote antioxidant activity and support healthy skin and immune function.
This formula is a great choice for anyone looking to support their immune system, promote healthy skin, or boost their antioxidant intake. It's also a solid option for those who prefer a vitamin C supplement enhanced with whole-food-based citrus compounds rather than vitamin C alone. It's made without starch, sugar, artificial flavors, or colors.
The typical recommendation is to take one tablet daily with a meal, though you can check the label for specific serving suggestions. Some customers increase their intake during times when they want extra immune or antioxidant support. As always, consult your healthcare provider if you have questions about the right amount for you.
Nature's Sunshine offers several vitamin C options, and this one stands out because of its blend of citrus bioflavonoids, hesperidin, rutin, and rose hips — compounds that naturally complement vitamin C and may enhance its benefits. If you're looking for more than just standalone vitamin C and want the added support of these synergistic plant compounds, this is an excellent choice. It's one of our customers' favorites here at Caring Sunshine.
