## Description

Perque Potent C Guard Powder, 8 Ounce

Review: Great product! Worth the money if you have it! - This is a great product. When I take it, my skin looks so much better, brighter, and tighter, and my joints feel better. I normally get it here on desertcart.com, but today I needed it and could not afford it, so I got it off eBay for $23. When it comes in the mail, I will see if it really is the same one. They had ones on eBay for $29 as well. They expire in 5 months, which is not bad to me. Anyway, it is worth the full price because it is a very high-quality product, and I feel like you are taking a chance when you get it off of eBay. I hope this helps.

## Questions & Answers

**Q: What is it sourced from?**
A: PERQUE Potent C Guard is a pH-balanced, vegetarian, allergen-free, and completely buffered mineral ascorbate. It uses 100% l-ascorbate, fully reduced, corn free, which works harder, more quickly and more persistently in the body.*

PERQUE Potent C Guard contains a balance of essential minerals: calcium, magnesium, potassium, and zinc.

**Q: when will this item be back in stock?**
A: BEWARE!!! Do not purchase during a heat wave, and Amz warehouses are NOT a/c'd. This product EXPIRES when exposed to 86F or above temps. Mine was caked on at the bottom, had it a few months in a/c'd home. Get to the 1/3rd bottom, it's brown, caked on, taste bad and will not fizz it's expired.

**Q: is this product vegetarian?**
A: Beware! It gets destroyed in the heat. Received mine in the summer, looked fine despite heat wave. Get to the bottom 1/3rd and it's BROWN caked on and expired/unusable! :-(

**Q: The seller keeps changing on this page & perque tells me they don't licence & is fake. how do you (seller) get this? prove it's not fake?**
A: I would trust what Perque is telling you. I now buy this product only from my naturopath.

### ⭐⭐⭐⭐⭐ Bet Vitamin C there is.
*by E***N on April 18, 2024*

When my son entered daycare, I was getting sick every 2-3 weeks. I tried all the name brand fizzing powders, fizzing tablets, and capsules that I cannot mention by name in this review. I also tried magnetic necklaces. I was talking to a chiropractor at the gym one day and he mentioned the Perque Potent C guard and told me to take a 1/2 heaping teaspoon twice a day at the first onset of symptoms for at least a week. Worked like a charm. Now this stuff is a bit expensive and used to be a lot harder to find before Amazon started carrying it, but it's worth it. I also add some lemon flavoring to it - either powder or liquid flavor enhancer to just make it more enjoyable - otherwise it tastes like sour metal (to me). Make sure that you keep it sealed and not exposed to oxygen as much as possible. What makes this unique is that the vitamin C is not exposed to O2 and thus is not oxidized. For me this means that once opened, the bottle only lasts about 6 months before starting to turn yellow. Once you start to get yellow clumps it is not as effective. Leave the desiccants that come with it in the powder as this helps.
