Many appreciate the inclusion of rose hips and bioflavonoids for added benefits. Users report improved immunity, fewer colds, and increased energy levels.

Overall, it is a well-regarded supplement that many plan to continue using.

Powerful Daily Vitamin C Support
Verified purchase
The NOW Foods C‑1000 tablets are excellent in quality with a strong ingredient profile that delivers a solid dose of Vitamin C. The package of 250 tablets is generous and great value for everyday use. I take one after meals and have noticed real benefits in my immune support and overall wellness with regular frequency. These are easy to swallow and gentle on my stomach, making them perfect for daily supplementation. I feel more resilient during cold season and more energized overall. Highly recommend for anyone looking for reliable Vitamin C support!

A reliable vit C
Verified purchase
I’ve been taking NOW Foods C-1000 every morning as part of my daily routine, mainly to make sure I’m getting a steady and reliable source of vitamin C. Even though I haven’t noticed any major or dramatic effects, I still appreciate having a simple way to support my general wellness. What I like most is that it’s easy to take and hasn’t caused me any discomfort at all—no stomach irritation or aftertaste, which is often a concern with stronger supplements. The capsules are straightforward, and I find it convenient to stick to one consistent dose each day. Even without noticeable changes, I still feel good continuing with it, knowing I’m keeping my vitamin C intake on track. I would recommend it to anyone wanting a dependable daily supplement.

This product has quickly become a favorite for both me and my mom. We love how it provides a strong boost of vitamin C to support our immune health, especially during busy or stressful times. Unlike many other supplements, it doesn’t leave any unpleasant aftertaste, which makes it easy to take regularly. It feels gentle on the stomach . Highly recommend for anyone looking for a clean, effective vitamin C , antioxidant supplement.

Great product!
Verified purchase
If you're looking for an exceptional Vitamin C supplement, I highly recommend this one. Great product, affordable price, quality ingredients. The size is good. I take 1 tablet daily, in the morning, with vitamin D3. Vitamin C is a cornerstone of immune health, vital for a robust and well-functioning immune system. Essential for collagen production.
