If you’re looking for a vitamin C supplement to add to your daily routine‚ you should be sure to choose one with the most health-promoting potential. Perque’s Potent C Guard is the most powerful vitamin C supplement on the market today.

Potent C is a pH-balanced‚ allergen-free‚ vegetarian and completely buffered mineral ascorbate (vitamin C).

Vitamin C

Research has confirmed that vitamin C plays a key role in collagen repair and formation‚ immune system function‚ joint function‚ antioxidant protection‚ energy production‚ detoxification and more. As a pure form of vitamin C‚ Potent C Guard enhances the hormone production and function of the body whenever needed‚ and it helps the body adapt better to various conditions.

Because vitamin C is water-soluble‚ it is not stored in the body for later use. This could be looked at as a positive or a negative. Because the body doesn’t store excess vitamin C‚ it would be very difficult to overdose. On the other hand‚ you must be sure to get a steady flow of this essential vitamin in your diet in order to maintain good health. The amount of vitamin C one needs depends on their level of stress‚ exposure to toxins and alkaline reserve. The best estimate for your vitamin C needs can be estimated by your diet and exposure to stress‚ or as recommended by your healthcare professional.

What Sets Potent C Guard Apart from the Rest

Potent C Guard by Perque prevents free radicals from harming the ascorbate. The cofactors‚ metabolites and transporters included in Potent C Guard work to enhance the body’s absorption rate and tissue action. With Potent C Guard‚ you don’t have to worry about any of the side effects that you might encounter while taking other‚ inferior vitamin C supplements. This supplement contains an adequate balance of the essential minerals: potassium‚ magnesium‚ calcium and zinc. Studies have shown that most Americans are deficient in one or more of these key minerals due to food processing‚ toxins‚ ill health or stress.

In addition to it being great for your overall health‚ Potent C Guard also tastes great too‚ so you’re more likely to stick with it in your daily routine. When you mix this powder with water or juice‚ the result is a tasty and slightly effervescent beverage. This powder is made with an exclusive triple re-crystallization process that creates an end product with unprecedented bioactivity and purity.

Benefits of Buffered Ascorbate

Many factors can contribute to high blood pressure‚ including obesity‚ alcohol consumption‚ a high-fat diet and physical inactivity‚ but research has shown that buffered ascorbate can help mediate the ill effects of these things by protecting the endothelial walls of blood vessels‚ increasing nitrous oxide‚ and inducing the production of collagen. The buffered ascorbate in Potent C Guard has also been shown to lower the body’s burden of toxic minerals such as mercury‚ arsenic‚ nickel‚ lead and cadmium.

      I put this in my drinks, in my tea and I even added it to chicken broth when I was sick. It is sour but I don't mind.

      Pros

      I like that it has a little foaminess when you add it to your drink. I also like that I can add more or less as needed.

      Cons

      I have never found a vitamin c that I could take plenty of and not feel horrible pain in my stomach. Everyone around me was getting sick with the crud...I was not feeling well and had to take a 5 day course of antibiotics. The crud came back but I had ordered this product. I began taking 2 tablets every 3 or 4 hours with a hot tea made with Thieves oil. Lemon oil and medicinal honey. I got better very quickly. I am a teacher and this really is now part of my daily routine this time of year. This is powerful stuff and great for adrenal fatigue as well.

      Pros

      It just works!

      Since taking the Perque Zinc Guard and Potent C Powder over a year ago, I have not gotten sick. Not a cold, not a flu, not a sniffle. These two items are what I swear by to keep my immune system full speed ahead year round. The Potent C Guard also helps keep me regular. If you have trouble with constipation, I highly recommend this in addition to 400 mg per day of magnesium.

      Pros

      Easy to take and highly absorbable.

      Cons

      A but pricey, but a little goes a long way.

      Dr. suggested it years ago for constipation and general colon health and have been using it ever since. Also there is no heartburn. acid reflux, or cramping.

      Pros

      Easy to use. Tart flavor but not sour or undrinkable. Could use simple syrup if too tart.

      Cons

      Nothing about this product I don't like

      I think this is a great product, made by a great lab and is corn free (so hard to find that). For me, I can't take the product as directed, I have to take 1/2 the amount because it makes my stomach hurt. It says buffered but it is not buffered enough. I do have better overall health when using it, but I can't use everyday or it irritates my stomach too much.

      Pros

      Very high quality, no corn ingredients, can mix up a custom dose.

      Cons

      Stomach irritation, can't use every day.
