I'm really pleased with this vitamin c. it's supposed to be easier to absorb (vitamin c should be taken on an empty stomach) and this one doesn't hurt my stomach at all! has a bit of a tang to it if you hold it in your mouth for more than a second but other than that it's great!
Dr.s Best are very hight quality products. This form of C allows the body to have sustained levels of vit. c. I really felt it helped to make my nails stronger (this was unexpected) and our son says it helps him sleep a little better as it helps the adrenals and their cortisol production.
Vitamin C is the base vitamin for everyone. I can't have fruit (cause it a lot of sugar) . then Vitamin C here is the way and yes it usefull with protein and build collagen base. and Immune for our body for this time need to be strong. Please click "Yes" 👍for my review if its helpful to you. Thank you:)

Plus the packaging and sizes were perfect. over all good quality. i love the smell and the looks of it. im looking forward to purchasing another one!
This was a product I purchased more than once. It was good. I particularly liked the time release aspect. After that I relied on my multi and other supplements for Vitamin C. Because of the pandemic worries and other issues, this year I tried and liked a California Gold Vitamin C which I am pleased with for now.
There are many forms of vitamin C available (ascorbic acid, sodium ascorbate, calcium ascorbate, liposomal vitamin C, etc.) but there is no compelling evidence that one is much better than another. For instance, natural vitamin C, such as from rose hips, is the exact same compound, L-ascorbic acid, found in most synthetic vitamin C supplements.
One hundred percent absorption efficiency is observed when ingesting vitamin C at doses up to 200 mg at a time. Higher doses (>500 mg) result in fractionally less vitamin C being absorbed as the dose increases. Once plasma vitamin C concentrations reach saturation, additional vitamin C is largely excreted in the urine. Therefore, we should pay attention to the quantity, not just the quality.
To be sure you're getting the daily requirement of vitamin C, a supplement providing roughly 50 mg to 100 mg of vitamin C is sufficient for most adults and is quite safe.
Clinical trials published in the April 21, 1999 issue of the Journal of the American Medical Association. It concluded that 200 mg a day is the maximum amount of vitamin C that human cells can absorb, making higher dosing on a daily basis pointless.
Be aware however, that taking more than 500 mg of vitamin C per day on a regular basis (which will saturate your blood with vitamin C) may increase your risk of developing cataracts (the clouding of the lens of your eye), and taking more than 1,000 mg per day may also increase your risk of kidney stones. Diarrhea can result from a single dose of more than 2,000 mg for an adult and lower amounts for children.
Also pay attention that as vitamin C is an acid, products formulated as capsules or tablets may be safer for your teeth than high-dose liquids, powders (mixed into liquids), chewables, or gummies.
