Thanks for your feedback!

Did absolutely nothing for my broken capillary on the nose nor on the old one, which was treated with laser and I have only small redness in this area. So I can say for sure - is is not good source of vitamin C or flavonoids. Seek for other. People are talking positively about acerola.

Thanks for your feedback!

My Favorite Vitamin C+mixed Bioflavonoids

Posted by RubiesHealth on Jun 14, 2012 | Verified Purchase

I wish this comes in bigger bottles. I always order in 4's. The "Extra" includes citrus bioflavonoids, rutin, rosehips and hesperidin which enhances the function of vitamin C in providing overall cellular protection. It is totally soluble and can be opened and added to water or juice for children who cannot swallow capsule. One capsule can be divided into 4 - 5 doses for children under 3 years old. 500mg twice daily is a good maintenance dosage for me. When I increase my running intensity, I increase to 4 times daily to aid muscle recovery. I no longer experience unexplained bruising since taking this.

Thanks for your feedback!

great way to take vitamin C

Posted by iHerb Customer on May 15, 2012 | Verified Purchase

soft, easy to swallow capsules. No horrid orange flavours, artificial sweeteners, sugar etc as found in most other Vitamin C supplements. Just tasteless encapsulated ingredients. Purchased based on Bee Wilder's recommendation.

Thanks for your feedback!
