Good quality

The NOW Foods Supplements, Vitamin C Crystals makes it easy to take my vitamins. I just add it to my smoothie in the morning and I don't even taste it. I like that this is a powder and is easy to take. I was having a hard time taking capsules for Vitamin C because it seemed like they were so big I kept getting them caught in my throat. So I was really happy to find this product.

Lasts forever!!

This little bottle literally lasts forever. Since the dosage is so high, I can split it in half or even fourths and still get a TON of Vitamin C. I love taking this periodically when I feel a little cold coming, or during travel. It is tart without being too sour. The ingredient list is really clean too.

Great way to add vitamin C

I add 1000 mg as an ingredient in my morning drink for immunity and antioxidant effects. It tastes good, as ascorbic acid should. Powder is the cheapest and most efficient way to take it, with whatever potency you decide. it's packaged well and simply in a tub. My stomach handles it well,

I feel like dissolving crystals of ascorbic acid is a more efficient absorption . I even use it in some spray for my skincare at night. I take it on water or any other liquid. Sometimes I even put a little on food and it’s like adding some lime. Just don’t take more than a spoon, or you can experience diarrhoea bc the dose has been increase. Even if you do, it’s not a bad feeling, but consult your dr. if so.

Love this form of vitamin C

Vitamin C is a must have in your arsenal for immunity and good health. I really like powder form because it’s so versatile and I can adjust the dosage to whatever specific mg I need. I use it in baking, as an ingredient in skin care recipes which has a great effect on my skin, and just mixed in a little water to take as an antioxidant.

Ascorbic acid is the pure, acidic form of Vitamin C, while buffered calcium ascorbate is a gentler, pH-neutral version where ascorbic acid is bound to a mineral, typically calcium. The main difference is digestive comfort: calcium ascorbate is less likely to cause stomach upset, making it a better choice for people with sensitive stomachs. I buy both, one for myself, one for my wife (high stomach acidity).
