At Doctor’s Best, we aim for the exceptional. 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: Easy on the stomach, and best I've tried - Easy on the stomach, assimilates (or at least I think so), and seems to be the best one I've tried. Highly recommend.
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.

## Features

- PureWay's 12-Hour Vitamin C is a unique form of the essential vitamin C since it contains vitamin C lipid metabolite. Superior cellular retention, bioavailability, and absorption of vitamin C compared to other sources
- IMMUNE, HEART & ENERGY SUPPORT: provides strong vitamin C support because of improved bioavailability, bioactivity, and absorption
- HEALTHY CARDIOVASCULAR SYSTEM: based on a great deal of prospective studies that evaluate vitamin C intake in large populations that are monitored over time, the highest vitamin C intakes are linked to improved cardiovascular health.
- POTENT ANTIOXIDANT: Free radicals can cause oxidative stress, which can cause cells to age prematurely. An antioxidant helps combat these free radicals.
- High vitamin C intakes boost cardiovascular health, according to long-term study in large populations. Several large studies on healthy people who take vitamin C supplements show that they help maintain heart function.

### ⭐⭐⭐⭐⭐ This Sicky No Longer Gets Sick

### ⭐⭐⭐⭐⭐ Product tested clean by third party
*by M***M on September 13, 2025*

Not all Doctor's best supplements are free from unsafe amounts of heavy metals (like the magnesium supplement) but the vitamin C tested clean. My source is Lead Safe Mama.
