High quality!
These are my favorite Vitamin C. It is a complex, which is good. Easy to swallow, and easy on the stomach. I feel very confident of the formulation and the company. All of Nature’s Lab products are quality, so don’t hesitate!

Best vitamin C formula on the market!
This is one of the best vitamin C products on the market. The combination of quercetine together with this vitamin C formula is the best I’ve sampled and one can really see results. I’ve been using it for over 15 years. This formula was also manufactured and sold by Vitacost as their advanced C with quercetine and bioflavonoids. When I ran out during the pandemic, I was hard pressed to find a replacement and eventually discovered that the original manufacturer was nature’s lab and it was selling under private label at Vitacost.Truly, the best vitamin C formula one could ever hope to find.

SUPER VITAMIN C. With Quercetin & Citrus Bioflavonoids.SUPER VITAMIN C. With Quercetin & Citrus Bioflavonoids.
I really liked this vitamin C. I did not fall heavy or cause stomach discomfort, which was something I worried about. I also like that it has no flavor, so if you do not tolerate citrus fruits well, it can work very well for you. It feels like a fairly complete product because it helps metabolism, skin and bones. In addition, it gives me confidence to know that it is 100% natural. Overall, I thought it was an excellent product and I would buy it again.
