Energy!

I bought this to take alongside an iron supplement I was taking. The amount of servings in the package is wonderful and I know that it will last the entire winter season for my family. Great for immunity in the colder months and the flavor is just “sour” like a lemon. Doesn’t taste bad!

One of the best Vit. C's out there!

I typically use NOW's vitamin C but when I saw that Doctor's Best had a pure vitamin C powder, I jumped on it! I used it in my smoothie daily- super easy to take, no mess- no fuss and perfect for those who can't or just don't want to take it in pill format! Huge amount in the tub- it truly lasted forever!

Good basic powder Vitamin C

I bought this supplement because I wanted Vitamin C to increase absorption of Iron supplement I take. Although I recently got to know the importance of Vitamin C in immunity and collagen production in the body. And Dr. Sarah Myhill advised on drinking in warm water instead of pills it so that it helps extra immunity when it passes through the throat. I appreciate the package and the pre measured scoop so it’s easy to take 1 gm per day. I usually add more water to reduce acidity and make sure to brush my teeth afterwards.

Good

Good quality composition of ingredients, the size is 250 g. so it goes a long way. I like that it's Quali-C pure C vitamin, which is the best quality. Vitamin C is very important for immunity, and it's a great antioxidant. It doesn't bother my stomach and is easy to use.

Best Vitamin C

The ingredients are excellent. I take three spoonfuls, three times a day. I’ve been purchasing this for about four years, and I plan to keep buying it. However, when I scoop it into my mouth, I sometimes spill a bit of the powder. If you pour it directly into your mouth and then immediately drink some water, it’s much easier to swallow. I prefer the powder form over tablets.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!|

This powder is a game-changer for customizing my vitamin C intake without any fillers. I mix a tiny scoop into my morning orange juice, and it dissolves completely with no gritty texture or bad aftertaste. I've noticed I've gotten through this winter without a single cold, which is a first for me. It's an incredibly cost-effective way to get a high-quality, potent dose of vitamin C.
