Excellent vitamin C powder

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

A good C powder for smoothies

Dr. Keith claims his brand has smaller molecules than others so is much more absorbable than others. I have no idea if this is true but i went for it “just in case”.

The best Vitamin C I had found so far.

For me, swallowing pills is very hard to do. So whenever I can find an alternative, I will try it out. I have been a fan of Dr. Keith for many years now and have taken most of his products at one time or another. But his vitamin C is one of my favourites and will always remain part of my daily routine. The quality and taste is just something you can hardly find anywhere else and when necessary, taking higher dosages will not give me any grief. His no-nonsense, clear cut approach to life has earned my respect and I have full faith in all that he does as well as his products.

Quality guarantee was nice.

I liked that they used a bunch of silicone packets to keep it from oxidizing. I didn’t like they doubled the price after my first order.

It helps your immune system.

We purchase several items from Dr. Keith. I love his explanation of the benefits of the product. As far as the Vitamin C powder goes....the day I received my jar, I was starting to feel feverish. My husband mixed some of the powder up in a glass of water for me. I drank it .....really very very little taste. I didn't get sick. Felt fine the next day. I was thrilled.

Too pricey and questionable taste

Looking at the product page, I was expecting this megadose of Vitamin C powder to taste very fruity, like oranges. However, that is completely not the case. It has some distinct taste to it, but it’s not very appealing at all. If anything it just tastes like water with salt added to it. I wish it would have just a bit of an appealing taste so I can just mix it with water without adding any juices that are high in sugar. Another point is the price point. At almost $45 far a small jar, this product seems grossly overpriced and you can find a lot of other megadoses of vitamin C powder with a better taste for a lot less.

Convenient and Potent

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..
