I second the "non-Chyy-nah" sentiment. Also, liposomal vitamin C rivals - and in some cases, exceeds - the absorption rate of intravenous C. Simple powdered C is great, for sure! Though, it does have a much lower absorption rate and can cause digestive side effects for many, especially in large doses. I tried a "vitamin C flush" a while back (at the time with simple ascorbic acid powder). 1,000mg every 15 min. Got up to 50,000mg (over 12 hours in) and still did not have the telltale bowel evacuation. Pretty sure I had scurvy. kek I have been taking liposomal C (China-free, made with sunflower lecithin, NOT soy) regularly since then. Even without mega-dosing, it has changed my life.
