A better way to C.

Vitamin C (or ascorbic acid) has made countless headlines for its impressive health benefits, and for good reason. This essential vitamin is a powerful antioxidant that bolsters your immune system.* And since our bodies cannot produce it, many turn to supplements to get their recommended daily amount. Q®-C is a brand of ascorbic acid manufactured in Scotland that is recognized for its quality and reliability. Make getting your daily dose of Vitamin C refreshing and easy by mixing this powder into your favorite fruit juice—your immune system will thank you.

Great flavor when mixed with sparkling water and it can help you reach your flush goals. Also works great during cold and flu season. Highly recommend reading up on work from Dr. Andrew W. Saul on the amount of Vitamin C it takes to make an impact on the ailment you might be suffering from, such as flu/cold/viruses/etc.

I think this product works well. Easy to take with my morning water ritual of this Vitamin C, collagen powder and apple cider vinegar. Everyone got a cold and I didn't. Also works well with collagen to keep skin looking nice!

I drink this everyday in my electrolyte drink and it has no real flavor, more like a sour base so it's great in a drink mix or juice… 1,000mg in each tiny scoop, so if you are sick you can do a Vitamin C flush and shorten the length of your illness. I had my son-in-law use this with other immunity builders and had his flu for only three days, compared to his usual 7-10 days.
