This is an excellent product!. A dose of unoxidized product will ward off any cold you feel coming on and will very quickly help to get over the cold. The big problem with this product is the packaging. Anything packaged in plastic will oxidize rather quickly, but this product oxidizes extremely quickly. After opening, it will turn brown in a matter of days. I always transfer the contents to an empty Pines Wheat Grass bottle as that product is in glass with a very tight seal. Peanut butter jars in glass with a seal in the cap also work. The last two plastic tubs I purchased from Amazon had already started to turn brown even though the expiration date was 2021. This is probably probably due to Amazon not providing enough air conditioning in their warehouse or UPS shipping in hot trucks. Again, this is an excellent product. The fact it oxidizes and turns brown so quickly actually points out to how potent it is. I do not recommend using the product after it turns brown. It is very important to get it out of the plastic tub as soon as you can. I don't know why they use such poor packaging for such an excellent product, but I don't understand why ANY company would package in plastic due to the rapid oxidation that takes place, let alone that plastic pollution is taking over the planet and getting worse every year. I hate buying this in plastic, but until the company wakes up to how fast their product oxidizes in plastic, there is not much I can do. The containers of anything purchased in plastic will be around for thousands of years. Plastic can only be recycled once and even then, you are adding to the pollution. Any product in plastic loses value very quickly. I always purchase products in glass if possible. It is non toxic and if the caps have a seal in them, the product will stay fresh infinitely longer than any product packaged in those cheap plastic tubs by companies that don't care about pollution or product quality. It is sad when good products are packaged so poorly just to make money for a company that doesn't care about quality.

I have used many, many vitamin C products in the past but hands down this is absolutely the best vitamin c I have ever found. It is very effective and due to its purity of just including sodium ascorbate with no added minerals, a bit more of this product can be used safely in times when feeling very under the weather. Due to the fact that it is also buffered at a non-acidic, neutral pH, it causes absolutely no intestinal bloating or discomfort. I order a tub of this monthly and use on a daily basis in smaller amounts and larger amounts when I am feeling under the weather. It is truly an amazing project, and I 100% plan on using this product for the rest of my life.

The product is very good, but after a few shipments one was received partially opened and with signs of moisture in the powder. Since I'm not completely sure it is not contaminated, I'm not going to give it to my kids. Tried to return but was unable to. I contacted the seller and did not do anything to help.

Taken straight in water, not so good. Mixed in room temp coffee before adding ice/creamer, not bad. I use half a scoop every morning(~2 grams) with half a scoop of Collagen Peptides Hydrolyzed Protein Powder (unflavored, hormone-free, grass fed & pasture raised). I think it's helping to improve skin and upper respiratory issues.

Purchased this from Amazon because it was convenient. Product is rock solid and has a strange smell. Don’t even want to think about what that indicates. I’ll go back to ordering from what I know to be reputable sellers. Waste of money!

Product arrived fresh! I had it for a few weeks and its not turning any weird colors as mentioned by other reviewers. I feel a noticeable difference in my energy levels since taking this. I am recovering from Lyme and other co-infections so I need all the energy I can get. I was so impressed that I sent a batch of this to my twin because he works long physically taxing days and needed a boost. He was equally impressed at his increase in energy as well. Great product!<br />Update! 10/24/20<br />I ordered this product again and the taste is odd and so the smell. The scooper is also different. I am afraid to consume it and there is no one to contact about this. Plus you can't return it. I'm very disappointed. I can't tell if maybe its a fake or if they changed the formula. I would order direct from the company website in the future. Sometimes these Amazon sellers are tricksters.
