Enhanced Non-Acidic Vitamin C For Superior Antioxidant Protection Dietary Supplement The benefits of vitamin C are energized in this formula, which is designed to make more vitamin C available for immune support and free radical scavenging. After vitamin C carries out its anti- oxidant function of neutralizing free radicals, it is oxidized and spent. The unique blend of compounds in SYSTEMIC C™, including alpha-lipoic acid, L-Cysteine HCI, quercetin, and grape seed extract, help to reactivate and recycle vitamin C in the body. This provides the body with increased antioxidant activity, an upgraded, robust C for healthy aging, immune health and heart health. Reactivating vitamin C allows this important vitamin to continue its vital functions.

There's probably nothing you can do about it, since it contains cysteine and vitamin C, but the yellowish powder inside the clear capsule turned brown in places pretty quickly after opening, which made me a little hesitant about drinking it. It seems like it's better to be cautious, like storing it in an airtight container in the refrigerator.

Somewhat helpful

I am 32 years old and suffer from chronic inflammatory response syndrome (CIRS) from a toxic mold exposure. Since then I am looking for high quality products that are affordable. This product has great ingredients and I really like the packaging. My main concern is insomnia and inflammation. I find this to be somewhat effective in dealing with MCAS, but not as much as I would like. I'm ok with the size of the capsules too.

Good concentration but has some smell

It has high concentrations of vitamin c and flavanoids add extra antioxidant properties. The capsule size is okay, however it has some smell and it burns my stomach if taken before meal. No issues after meal. Potency is okay but will come back to other brand because of smell and burning issue

vit C

I can’t really say or give any advice just yet – we haven’t had a proper go at it; we need a bit more time. Ingredients, packaging, size, taste, quality
