What we think

Maybe you are sick of fighting a mid-winter cold each year or worrying about catching something in transit to your next competition. Why not add Thorne ’s Ascorbic Acid (Vitamin C) to your list of regular supplements?

The truth is we could all use an immunity boost, especially when we are pushing our body to its limits and using all of its energy to rejuvenate our muscles in between workouts. During the times when you’re feeling extra healthy, Vitamin C still benefits the body in a variety of ways, including, promoting healing and injury repair, liver detoxification, collagen synthesis, increased blood flow, increased oxytocin release, and maintaining various brain functions.

All in all, its something that can benefit us regularly, not only during times of weak immunity. 


We are abiding by their guidelines of 1 capsule daily.

This product is quite pricey as are Thorne's other products. However, it has been great on my stomach, and my husbands. We take 2 in the morning and 2 in the evening without any problems. We need a lot of vitamin C for pyrolle disorder and undermethylation but many brands cause problems, expecially the powders. So would recommend this for anyone.

I've been using Pure Ascorbic Acid One Gram by Thorne Research for decades. It's the only vitamin c product that doesn't upset the stomach whatsoever. I've taken 20 in one day to get a virus and it really, really, works

Bought this for my 9yr old for when he appears to be getting ill. He has no trouble with these small-medium capsules. According to USA guidelines it's okay for bigger children to have 500mg Vit C a day. So one of these a day if no other vitamin C is given. I don't give him supplements every day.
