The benefits of vitamin C are highly publicized. Clinical research has confirmed the nutrient’s central role in critical processes including‚ but not limited to:


  • The maintenance of proper immune system functioning

  • The formation and repair of collagen

  • Joint functioning

  • Energy production

  • The functioning and protection of antioxidants

  • The detoxification of vital organs


Common foods that contain this vitamin are citrus fruits such as oranges and leafy green vegetables. However‚ you may not be getting sufficient amounts from your diet—that’s where a convenient supplement can help.

There are many products already available on the market that offer vitamin C supplementation. What makes PERQUE’s Potent C Guard the best source of the vitamin? It boosts the production and effectiveness of hormones‚ as well as enhancing your body’s ability to adapt when facing changes. It also supplies a much needed source of ascorbate‚ which can become essential during periods of extreme stress‚ the elevated presence of toxins‚ or allergic reactions. Potent C Guard’s fully-buffered mineral ascorbate is the form proven to be the most effective‚ since it works faster and more diligently throughout the body.

Potent C Guard protects ascorbate from the threat posed by free radicals. In addition‚ the formula’s cofactors‚ metabolites‚ and transporters show the ability to enhance absorption and tissue activity. At the same time‚ Potent C Guard has none of the unpleasant side effects associated with some other vitamin C supplements.

Potent C Guard’s exclusive formula also includes a balance of essential minerals like calcium‚ magnesium‚ potassium‚ and zinc. Most Americans suffer from a deficiency in at least one of these key minerals due to stress‚ processed food‚ ill health‚ toxins‚ and other factors.

For over two decades‚ Perque has been formulating and manufacturing safe‚ effective‚ and unique dietary supplements. Perque products are often included in prestigious clinical studies‚ and have been shown to have more bioavailability than competing products. Founder Dr. Russell M. Jaffe’s goal has always been to integrate conventional medicine with a prevention-first mentality.

      I love this Vitamin C

      from PLANO TX on 3/08/2020
      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

    • Keeps me well

      from East Texas on 2/07/2020
      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!

      Cons

      The absolute BEST vit. C on the market!

      from Woodinville WA on 11/20/2019
      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.

    • Easiest Way To Take Vitamin C!

      from Wisconsin on 11/14/2019
      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

      Great product

      from Maryland on 10/16/2019
      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.
