With some collagen as you can see, my nails grow within a month from taking a breakage of Acrylic nail tips. Yes, I’m taking a Nail Tip break Not taste not bad. Its powerful, It doesn’t Make my stomach upset. It’s good for immune system support when it’s cold outside or just taking it through the season. It works wonders for my allergies.

This is a good choice for vit c mix

Love it!
I've been using Doctor's Best Vitamin C Powder consistently, and it has become my go-to vitamin C supplement. First and foremost, I really appreciate that it it vegan and comes in powder form. I feel this powder dissolves easily in water and is quickly absorbed by the body. I definitely notice a faster response when I’m feeling run down or need an immune boost. Another reason I keep repurchasing this is the high quality of the product. It's pure, no artificial ingredients, which gives me confidence that I'm getting a clean and effective supplement. Also, since it's powder, I can adjust the dosage based on my needs—whether it's a small maintenance dose or a larger amount when I feel a cold coming on. It’s also gentle on my stomach. I will definitely keep purchasing this vitamin c. Love it

Typical c supplements
It's vitamin c but just because it says doctors best, it means little. Be sure it is 3rd party tested.

My favorite vitamin c
I have tried many vitamin c supplements and this is hands down my favorite, I’ve been ordering it for years. I have even sent it to friends and family when they are sick. It’s the best quality- it is actually pure vitamin c and not filled with tons of additives and flavors. It does have a lemony sour taste but that’s because it’s not being masked by artificial flavors (I actually like the taste). Like others have said it doesn’t fully dissolve in water. You just have to get stirring it while you drink it. I take this every day.

Has become one of our favorite C products
I'm very impressed with Quali-C ever since I've been using it. I have zero digestive problems from it and it seems very effective. I had a major toothache that disappeared overnight once I started using this (took it every hour for 3-4 hours) and I also completely disappeared an oncoming cold doing the same. It's has very little taste, and you need a smaller amount to get the required dose (measuring spoon supplied). Just a tad pungent as you'd expect it to be, but it's easy to get used to and I'm actually starting to like it. I just use it in water but in a smoothie it would be pretty undetectable. It's extremely fine, not gritty at all, and dissolves instantly. I'm on subscribe & save with this now because I like it so much.

It dissolves in my juice and water completely so there's no residue and it's easy to swallow. The size and the value is perfect it lasts me for at least 6 months of use and I like the product and it helps me stay healthy
