I've wanted to try a vitamin C facial serum for a long time, but the ones I've found were so expensive. I found a recipe to make your own that wouldn't cost an arm & a leg. I also read that you need to use the &#34;ultra fine&#34; powder, so I ordered this & received it today. I have already made my first batch & it turned out great! You DO have to dissolve your C powder in water first before adding your glycerine & it took less than a minute of stirring for it to completely dissolve. I've already tried it out & there was absolutely no grainy feeling at all, so I'm very pleased with this! I'm also going to be adding some to my smoothies as well for the added health benefits. I will add the recipe below for the ladies who want to save a lot of money & make their own serum. I received this product on the date promised & it was carefully packed very well. I would definitely recommend this company & this to anyone wanting to make their own & save tons of money! This bag will last me forever because you use to little.<br /><br />Vitamin C Facial Serum<br />Start out with a 5% & gradually move up to a higher strength. You might feel a stinging at first, but if it's to bad, just lessen the amount of vit. C until you get adjusted to it.<br />Ingredients:<br />5% Serum 1/4 tsp. powder 4 tsp. distilled water 3/4 tsp. glycerin<br /><br />10% Serum 1/4 tsp. powder 2 tsp. distilled water 1/4 tsp. glycerin<br /><br />15% Serum 3/8 tsp. powder 2 tsp. distilled water 1/8 tsp. glycerin<br /><br />20 % Serum 1/4 tsp. powder 3/4 tsp distilled water 1/4 tsp. glycerin<br /><br />Mix your C powder into the water until it dissolves. Then add your glycerine. (personally I only added half the amount of glycerine & used aloe vera gel for the rest) And that's it! Quick & easy!<br /><br />This will only keep for a week as any longer will cause it to oxidize, so you need to make a small batch each week. It needs to be stored in a dark bottle & away from light or heat. I'm keeping mine in the refrigerator, but you can store it in a drawer too. Sterilize your bottle first. And should you notice your serum has turned yellow, that means it has oxidized & is no longer productive. Even if it does, this powder cost so little & will make SO much that it's no big deal to make another quick batch! I will definitely by buying more bulk products from them, as it's so much cheaper & you get a good quality product!

I love this product because it's in powder form so I can mix this with my drinks and has no flavor. I was a bit confused when I opened the bag because it looks like sugar crystals but it's not. I use this as a regimen to help me with my hypothyroidism as I could no longer afford to buy pills every month. Since starting the natural way on helping my thyroid get what it needs I actually feel normal which is a good thing! I was diagnosed four years ago and I always felt off and lethargic while taking synthroid, not to mention horrible mind fog. I'll be going to get my bloodwork done sometime next month and we'll see if this in conjuction to the other supplements is helping my thyroid.

I have read that this is great to use on your skin. I use this and Olive Oil on my face at night along after I put my mixture of Hyaluronic Acid, Vita C, DMAE and glycerine vegetable on. I really do see the difference in my skin. It looks younger! I will continue purchasing and highly recommend this product.

We recently purchased a golden retriever puppy and the breeder asked us to give him a lifelong daily Vitamin C supplement. She cited this article from Whole Dog Journal [...] which points out that "many studies have found that dogs (as well as humans) that are supplemented with vitamin C show greater resistance to disease, and a better ability to recover from injuries or illness."<br /><br />The powdered version of vitamin C from BulkSupplements gets great reviews and we found that the powder is perfect for adding to his food. We started him on 500 mg (1/8 of a teaspoon) daily. The breeder suggests we move up to 1,000 mg at three months, 2,000 mg at six months, and at one year of age give him 2,500 mg (approximately half a teaspoon) daily for the rest of his life.

Great packaging and fair price. I took off 1 star due to the uncertainty of gmo in the product. I pulled up the bulksupplements website and the picture on their site looks identical with the little man design but says bulksupplements on the label instead of puredepot. Clearly on the website it says non-gmo. Why is this not labeled on the package or stated on the amazon page? Since my product says puredepot instead of bulksupplements, I am uncertain if it is exactly the same thing. Other than that this is great with a light lemony flavor. Since only so much vit c can be absorbed by the body at once I take 1/8th tsp (529 mg) in the morning and another 1/8th in the afternoon. Build up slowly or it may upset your stomach.

I heard good things so I came here to purchase but researched it further and found that it is made from GMO corn. Ascorbic Acid is made from GMO corn in factories in China!!! GMO corn has the BT toxin (pesticide) built into it cells, it is also sprayed heavily with toxic herbicides (Round-up). Will not ingest or put on my face. I will stick to whole fruit forms of Vit C which I have read are proven to be more effective.
