Quali-C, the ascorbic acid used in this formula, is of the purest form produced by DSM in Scotland. DSM was the first company to synthesize vitamin C back in 1938, and is currently the ONLY producer of ascorbic acid/vitamin C in Europe. Doctor’s Best, Vitamin C with Quali-C is an excellent product, without fillers and does not cause stomach irritation.

@@@Shirochan Cancer Protocol@@@ Travel Use

I do high dose Vit C everyday with the powdered form mixed with L-Lysine. Bought this when Im out whole day or travelling. For those who cannot accept the sour taste of ascorbic acid should get it in capsule form too. This is a good C. The products I select are mostly clean without the fillers and additives. Your kind support of my healing cancer naturally is greatly appreciated. Thank you!

Good Option For Those Who Dislike The Powder Version!

Please check my profile for my review on this same product that comes in powder form. This is a great product for those who cannot handle the "sour" lemon taste of the powder version. My wife & oldest child take this as an option to get a high dose of vitamin C. Has helped to keep most infections (colds) away compared to before!! I still prefer the powder version for mixing in with citrus drinks (fresh lemon, calamansi, etc.)!

Doctors Best Vitamin C

Great product and mg, but the caps are a bit bigger than my ability to swallow them. Switched to another brand and they seem to work well.

Pure, powerful, and gentle — the best Vitamin C I’ve used

I’ve been taking Doctor’s Best Quali-C 1000 mg daily, and it truly stands out from other Vitamin C supplements. The quality of the Quali-C form makes a huge difference — it feels clean, absorbs well, and doesn’t upset the stomach. What I noticed: Strong immune and recovery support Keeps my energy and focus steady through the day Gentle on digestion — no discomfort, even on an empty stomach Perfect capsule size and no strange aftertaste Excellent quality from a brand I fully trust I take one capsule after lunch every day, and it’s now a permanent part of my supplement routine. If you’re looking for a reliable, high-quality Vitamin C, this one is perfect!

good!

This is the best vitamin C for those who find powdered vitamin C inconvenient to take. When taken with a meal, it doesn’t upset my stomach and feels gentle. It’s also easy to take when traveling or on business trips. The tablet size is quite large — definitely not small — so you need a full glass of water to swallow it smoothly. However, since it’s effective and made with good ingredients, I’ll continue to repurchase it.

The outstanding aspect of this product is the 360-count bottle, which provides a full year's supply if you take one daily. This makes it an incredibly cost-effective choice. While Ascorbic Acid is generally well-tolerated, those with sensitive stomachs may want to take it with food. For a high-quality, potent, and affordable foundational Vitamin C, this is an excellent and highly reliable option.
