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.

Lower Uric Acid 7.4 ➝ 6.3 👍
Verified purchase
Vitamin C may help lower uric acid levels, as studies show it can reduce serum uric acid concentrations. My young sons happen to have high uric acid level at 7.4 (probably genetic). I experimented by giving them a combination of Tart cherry + quercetin + vitamin C to help lower their uric acid without medication. Tart Cherry & Quercetin works as a xanthine oxidase inhibitor (similar to allopurinol). Vitamin C (Ascorbic Acid) acts as a Uricosuric Agent (increase excretion of uric acid in the urine). Their levels drop from 7.4 to 6.3.

Good quality and easy to take I’ve been using this regularly and I’m happy with the quality. Capsules are easy to swallow and I didn’t experience any stomach discomfort. The formula feels clean and well made. Too early to judge long-term results but overall a solid addition to my routine.

I’ve been using iHerb for years. The product variety is excellent and I always manage to find what I’m looking for—even items that local stores don’t carry. Delivery is fast and the pricing is very competitive. Highly recommend

Powerful Daily Chlorella for Clean Nutrition
Verified purchase
The NOW Foods Chlorella tablets are amazing in quality with a pure and potent ingredient profile — each 1 g tablet feels substantial and effective. The package of 120 tablets is generous and lasts a long time, making it ideal for daily nutritional support. I’ve noticed real benefits in energy and overall wellness with consistent frequency of use. The tablets are easy to swallow, and despite being unflavored, they’re gentle on the stomach and easy to take with meals. The nutrient‑dense composition makes it a great addition to a balanced diet if you’re looking for antioxidant, immune, and detox support. Highly recommend for anyone wanting a reliable chlorella supplement!
