Our formula combines vitamin C with lipid metabolites. This innovative blend is designed to enhance absorption, support increased cell retention, and aid in free radical defense, offering unique benefits over standard vitamin C.* Review: This Sicky No Longer Gets Sick - This vitamin C is of super high quality, as are all Doctor's Best products. I was taking a lot of different things for my immune system, which were working; however, I would still get a cold or sinus infection at least twice a year during the winter and early spring. Since I have added this vitamin C product into my regimen (for the last 10 months or so), I have not gotten since ONCE. And that says something because my WHOLE office got sick multiple times and I was pregnant during 9 months of that time and therefore more susceptible. I now simply can't live without this amazing supplement. Review: Vitamin C sustained release… - Doctor’s Best is one of the supplement brands that I trust. I have seen numerous positive reviews on YouTube. That said, I have recently started taking this “time released” version of vitamin C because of a vein condition I have developed. This replaces a different brand that had questionable efficacy. The one interesting point I can make is about the capsules themselvs. They are not marked in any way, so you have a be careful not to mix them up and other unmarked supplements. I see this as a good thing as no food coloring has been added to this product . ## Features - 12-Hour Vitamin C with PureWay-C is a unique form of the essential nutrient vitamin C that contains vitamin C lipid metabolites - Superior uptake bioavailability and cell retention compared to other forms of vitamin C - Non-GMO/ Gluten Free/ Soy Free/ Vegan ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001FXMDTM | | Age Range Description | Adult | | Allergen Information | Soy Free | | Best Sellers Rank | #21,113 in Health ( See Top 100 in Health ) #137 in Vitamin C Supplements | | Brand | Doctor's Best | | Brand Name | Doctor's Best | | Color | red | | Customer Reviews | 4.6 out of 5 stars 123 Reviews | | Diet Type | Vegan | | Diet type | Vegan | | Dosage Form | Tablet | | Flavor | Unflavored | | Flavour | Unflavored | | Global Trade Identification Number | 00753950001916 | | Item Dimensions | 5.4 x 5.4 x 9.4 centimeters | | Item Form | Tablet | | Item Weight | 0.01 Ounces | | Item form | Tablet | | Manufacturer | Doctor's Best | | Manufacturer Part Number | DRB-00191 | | Material Type Free | en_AE | | Model Name | Doctor ' S Best | | Model Number | DRB-00191 | | Number of Items | 60 | | Primary Supplement Type | Vitamin C | | Primary supplement type | Vitamin C | | Product Benefits | Immune Support | | Product benefits | Immune Support | | Specific Uses For Product | Immune System | | UPC | 753950001916 | | Unit Count | 60 Count | ## Product Details - **Brand:** Doctor's Best - **Diet type:** Vegan - **Flavour:** Unflavored - **Item form:** Tablet - **Primary supplement type:** Vitamin C ## Images ![Doctor'S Best - Sustained Release Vitamin C With Pureway-C 500 Mg. 60 Tablets 101015 - Image 1](https://m.media-amazon.com/images/I/61BM1vyfCgL.jpg) ![Doctor'S Best - Sustained Release Vitamin C With Pureway-C 500 Mg. 60 Tablets 101015 - Image 2](https://m.media-amazon.com/images/I/61AWDFroWOL.jpg) ![Doctor'S Best - Sustained Release Vitamin C With Pureway-C 500 Mg. 60 Tablets 101015 - Image 3](https://m.media-amazon.com/images/I/61z1yjp4mqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ This Sicky No Longer Gets Sick *by C***N on 9 April 2016* This vitamin C is of super high quality, as are all Doctor's Best products.
