Know Your Ingredients: Calcium Ascorbate

by Gio

Calcium_ascorbate

What it is
Calcium Ascorbate is a stable form of Vitamin C.

What it does
Calcium Ascorbate is an antioxidant that fights free radical formation and is necessary for collagen production. It also helps heal inflammation.

Side effects
Calcium Ascorbate is generally considered to be safe. However, products containing forms of Vitamin C can be expensive so make sure they contain a high enough concentration of this ingredient (don’t buy products that list it at the very end!) before purchasing. If the concentrations are too small, it just won’t do much for your skin at all.

There are many forms of vitamin C and every time I use it, I have to remind myself to use sunscreen.

Dao, yep, there are lots of forms of Vitamin C but this one seems to be better than others as it is stable. And I agree that sunscreen is a must when one uses products with Vitamin C, thanks for the reminder. 🙂

Alejandra, yes. That’s another form of Vitamin C and it has antioxidant properties as well.

Thanks Gia, im still looking for a good and affordable vitamin C product. Speaking about calcium ascorbate, I found a serum from Derma E, its Ester C serum with E Skin Recovery Complex, 60 ml for about 12 dollars so seems to be the most affordable Ill ever found.
Im wondering its vit C concentration, the company doesnt reveal it, what do you think? I leave you the ingredients list.

Water (Purified), Glycerin, Camellia Sinensis (Green Tea) Extract (Organic), Calcium Ascorbate (Ester C), Allantoin (Comfrey Root), Cetearyl Alcohol, Borage (Borago Officinalis) Seed Oil, Retinyl Acetate (Vitamin A), Tocopheryl Acetate (Vitamin E) (Vitamin E), Borage (Borago Officinalis) Seed Oil, Xanthan Gum, Phenoxyethanol, Ethylhexl Glycerin, Fragrance with Essential Oils

Alejandra, I think this is a great serum full of antioxidants that will benefit skin and help prevent and fight premature aging. Vitamin C is the fourth ingredient so it should be present in an amount high enough to work well and at that price, this serum’s a steal!

Trying to find some solid info on diy serums using calcium ascorbate since the acidity would be taken out of the equation, this would mean less irritation and dryness to the epidermis. I’d like to know your opinion, thanks.

Reace, calcium ascorbate, like all forms of vitamin c, is very tricky to formulate with. You need to get the ph right, the concentration right, the preservative system right… I love DIY beauty but this is one case where I’d stick to commercial serums.

Sure. I think i will look for a powder that could add to moisturizer or water before applying. Ive seen a review on a stable powder vitamin c you can apply without the negative sides. Tried calcium ascorbate powder with my moisturizer and broke out with a rash which changed the texture of my skin. Ive read Cosmedix pure c is good.

Reace, oh no! What a dreadful experience!

Vitamin C powder may be stable in its own bag. But once you put it in a DIY serum, it may become unstable soon. It all depends on how you store it and what preservative system you use. It can be quite tricky.

I have used it for 40 years. It’s my cure all. I take a daily maintenance dose of 1 teaspoon a day. I take bigger doses if I feel something coming on. I first started taking Vitamin C in citric acid form, but would feel squirmy after taking big dosses, so I switched to the low acid form of Calcium Ascorbate. I am 71, I don’t take any medication and do not have any aches and pains.
Three years ago I broke my femre badly. I took 16 gram over 12 hours after the operation, then kept the dose up to 4 to 6 gram. I didn’t go through what others around me were going through.

It also helped my grandchildren get Over severe attacs of chicken pox and helped another to clear burns after pulling a hot cup of tea on herself when a toddler.
