Its a form of Vitamin C but the funny thing is I took it and I got hemorrhoid reaction so i researched some side effect, it does encourage some bleeding. Tested it twice, everytime i took it it happened.

I’m very satisfied with the effect of sodium ascorbate! It’s a gentle form of vitamin C that doesn’t irritate the stomach, so I can even take it on an empty stomach. Within just a couple of weeks, I noticed I was catching colds less often, recovering faster after physical exertion, and my skin looked fresher and healthier. The supplement dissolves easily in water, has a pleasant taste, and caused no side effects. An excellent choice for supporting immunity and overall health!

Unlike regular ascorbic acid, sodium ascorbate is a buffered form of vitamin C. It’s gentle on the stomach, making it ideal for people with acid sensitivity

"I’ve been using NutriBiotic Sodium Ascorbate for months, and it’s my go-to vitamin C supplement because it’s gentle on my stomach. Unlike regular ascorbic acid, this buffered form doesn’t cause heartburn or digestive discomfort, even at higher doses. The capsules are easy to swallow, vegan-friendly, and free from unnecessary additives. I’ve noticed fewer seasonal illnesses since incorporating it into my routine. Highly recommend for anyone seeking a high-quality, stomach-friendly vitamin C!"

I love Nutribiotic Sodium Ascorbate — pure, high-quality vitamin C without fillers. It’s gentle on my stomach and doesn’t cause any IBS flare-ups, unlike other forms I’ve tried. The capsules are easy to take and really help boost my immunity and energy. Simple ingredients, great quality — definitely my new favorite sodium ascorbate!

Hood for those who are acidic. Very effective, high potent and good antioxidant. Mild on my stomach. No bitter after taste. This is very good quality Vit.C. Can help boost immunity especially now that the weather is changing. 1 serving size contains 850 mg of sodium ascorbate. Best of all this has no soy ingredients
