Dr. Keith's Own Buffered Vitamin C Powder 4000mg, Glycine & MSM 200g

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

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

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..

I have been taking Dr. Keith's Own Super C for a while. I would order from Dr. Keith's Own when I could, but to be honest, it cost more and I had to pay for shipping. Lower price and no shipping is a big plus from Amazon. When I had my checkup, my doctors assistant asked what I do to not get sick - I said take extra Super C. She said fantastic, and my doctor said "Keep doing whatever you’re doing". I am 75+ and I'm not on any meds. Thank you Dr. Keith for formulating this wonderful product.

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.

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.

I have used Dr. Keith's Own Super C for at least five years and have found it to be a huge help especially when I feel I am starting to come down with something. When I start to feel a cold or a sore throat trying to take hold I will take a dose and then go to bed (or take a nap if it is mid-day). When I wake up I feel fine with no remnants of the blooming infection. It is one of my go-to remedies I would not be without. I'm not always faithful about taking things every day but I have no doubt that I would notice a difference if I took this daily. Unfortunately self-discipline is not my strong suit.

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”.
