## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent vitamin C powder
*by C***P on March 3, 2025*

Excellent vitamin C powder. High strength with helpful additions. Tastes like Tang. No stomach upset.

### ⭐⭐⭐⭐⭐ Great tasting Vitamin C
*by A***. on April 14, 2025*

Great vitamin C product with ingredients that boost it's effectiveness. Tastes great too!

### ⭐⭐⭐⭐⭐ Convenient and Potent
*by W***Y on June 6, 2023*

I’ve tried capsules and powders and chewables. Nothing beats the convenience of Super C Powder. It easily dissolves in my morning juice without changing the flavor and provides a potent amount of high quality vitamin C, far more than the number of capsules one would have to swallow to get the same amount of benefit. Since we need around 8,000 mg a day, as compared to what is made by animals of similar weight, it is the quickest and most convenient way to maintain optimal amounts of C in the body..
