What customers say
Customers highly appreciate the NOW Foods C-1000 Vitamin C supplement for its quality, trusted brand reputation, and effective immune support. The product features a potent 1000 mg dose per tablet, natural ingredients, and sustained release, which many users find beneficial for daily use. However, several customers noted that the tablets are quite large and can be difficult to swallow. Despite this, the supplement is praised for being easy on the stomach with no negative effects. The packaging and delivery service are also commended. Overall, it is considered a great value for money and comes highly recommended by users for boosting immunity and overall health.

Excellent vitamin C for daily immune support
Verified purchase
I’ve been taking NOW C-1000 for a few months, and it’s one of the best vitamin C supplements I’ve tried. The capsules are easy to swallow, and I like that it includes 100 mg of bioflavonoids for better absorption. I’ve noticed improved immunity and faster recovery during cold season. Great quality from NOW Foods as always — highly recommend for anyone looking to boost their immune system naturally.

Great quality for the price! I take 1 pill by day and l'm feeling very well. It is especially good for the immune system in the spring. It is good to take it in the first half of the day, because later it can affect the quality of sleep.

Good amount of vitamin C
Verified purchase
I like these capsules because they have the right dosage, 1000mg, and they are time released, meaning the bioavailability will increase, overcoming the natural 500mg limit. Recommended!

Reliable Immune Support with NOW Foods Vitamin C-1000: Strong Quality, Minor Tablet Size Concern
Verified purchase
I recently started using NOW Foods Vitamin C-1000 (1,000 mg) and overall I’m pleased with the product. The formulation includes a full gram of vitamin C per serving and offers good value for the price.

I think this is a good Vit C but not as good as my previous Vit C. Prolly it depends on everyone’s overall health. Still great though

Strong Antioxidant Vitamin C
Verified purchase
NOW Foods C-1000 is a straightforward but very effective supplement that I’ve come to rely on. After regular use, I’ve noticed that I feel more resistant to seasonal issues, and my overall energy feels more stable. One thing I particularly like is that my skin looks a bit fresher and healthier, which is always a welcome bonus. The tablets are easy to take, and the quality is consistent. A simple yet powerful addition to daily health support.
