Great composition
Verified purchase
I choose this composition due to the flavanoids included as improves bioavalability quality. good potency and I mix 1/4-1/2 tsp of the powder into my electrolytes minerals in the morning, as the minerals buffer the acidity of the Citric Acid to make it gentler on stomach. Pure, clean, No sweeteners, so tastes natural, works well mixed into my electrolytes in water. Useful antioxidant, immunity, Collagen synthesis, etc, and supporting mineral absorption

great
Verified purchase
I am glad that the product is pure quality, and the ingredient without added sugar and palm oil and harmful seed oil content in it is what I have been looking for.. Many of the store bought products are so unhealthy and harm health .I am so glad to find iherb, and I already recommended so many people to find healthy products from the website. I feel so surprised that many of them haven't heard this website before .

True vitamin C that it is, this one tastes very sour/tart but is excellent to keep handy for Covid times during which I've bought two bottles. My skin does look better in a few days of taking a dose. The inclusion of bioflvonoids here is very clever, as vitamin C exists in nature as a complex, not as an isolated chemical form. Here the effort is a sort of recombination, maybe not as excellent as in a fruit form, but still gives a more natural feel than without.

This vitamin C powder is a staple in my morning routine, especially during cold season. I just stir a small scoop into a glass of water for a pleasant, tangy drink that's not too sour. I truly believe it has helped me fight off the bugs my kids bring home from school. It's an incredibly cost-effective way to get a high-quality vitamin C boost.

This powder is my go-to for a mega-dose of vitamin C whenever I feel a cold coming on. I love that it includes bioflavonoids, which I've read helps with absorption. It mixes easily into water or juice with a pleasantly tangy taste. A single container lasts forever, making it an incredibly cost-effective way to support my immune system.

The best Vitamin C
Verified purchase
This vitamin c is a really good product; it's truly one of the best brands. We've tried it as a family, and it works wonders for our children. I also like that it's not too expensive and has been tested to be chemical-free. Very good.
