When evaluating vitamin C‚ choose the supplement with the most health-promoting impact.

PERQUE Potent C Guard is the most powerful form of vitamin C on the market today.

The scientific literature has confirmed vitamin C’s key role in:

1) Immune system function.
2) Collagen repair and formation.
3) Joint function.
4) Energy production.
5) Antioxidant protection and function.
6) Detoxification and more.

Potent C Guard enhances hormone production and function as needed‚ and helps the body to adapt better. In addition‚ it is important to take the amount of ascorbate needed to keep an adequate supply in the cells. This varies based on levels of distress‚ toxins‚ acute and delayed allergy reactions‚ and cell buffering/ alkaline reserve. Optimum ascorbate use is based on calibration of need (see ascorbate calibration instructions) or as directed by your health professional.

PERQUE Potent C Guard is a pH-balanced‚ vegetarian‚ allergen-free‚ and completely buffered mineral ascorbate. It uses 100% I-ascorbate‚ fully reduced‚ corn free‚ which works harder‚ more quickly and more persistently in the body.

PERQUE Potent C Guard prevents free radical from harming the ascorbate. Also‚ the cofactors‚ metabolites‚ and transporters in Potent C Guard powerfully enhance absorption and tissue action. In addition‚ Potent C Guard is free of the side effects associated with other vitamin C supplements. Potent C Guard contains a balance of essential minerals: calcium‚magnesium‚ potassium‚ and zinc. Most Americans are deficient in one or more of these key minerals‚ due to stress‚ ill health‚ food processing‚ toxins‚ and other factors. Potent C Guard tastes better than other vitamin C powders‚ so you are more likely to stick with it. When mixed with water or juice‚ it produces a tasty‚ slightly effervescent drink.

Purity‚ purity‚ purity.
Potent C Guard is produced with an exclusive‚ triple recrystalization process. This innovative technique creates a product with unprecedented purity and bioactivity.

Unique PERQUE Features:

- Pure‚ hypoallergenic components.
- Organic base.
- Biochemically formulated.
- Includes cofactors that are usable in generating high-energy compounds.
- Made from 100% vegetable sources.

      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.


      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.

    • 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.


      It just works!

      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.


      Easy to take and highly absorbable.


      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.


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


      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.


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


      Stomach irritation, can't use every day.
