NOW Foods C‑1000 and really like it
Verified Purchase
I’ve been using NOW Foods C‑1000 and really like it — one tablet delivers a strong 1000 mg dose of vitamin C (with rose hips and bioflavonoids) which makes me feel more energetic and helps support my immune system. It’s easy to swallow (despite being a bit large) and doesn’t upset my stomach. Since I started, I’ve noticed I seem to get fewer colds and recover faster if I do catch one. Overall, it’s a simple, effective supplement for immune support and general antioxidant protection.

Vitamin C is a water-soluble nutrient that plays a vital role in maintaining normal immune system function. Vitamin C is also essential for the production of collagen (a structural protein in connective tissue), which means it's important for healthy skin, bones, and joints. It's involved in amino acid metabolism, neurotransmitter synthesis, and the absorption of many nutrients, such as folate and iron. It's also a highly effective antioxidant that can help maintain healthy tissues by neutralizing free radicals generated during normal metabolism and exposure to environmental stressors. This product was specifically designed to provide sustained-release vitamin C for a longer period of time. It includes rose hips as an additional source of vitamin C. Size: Regular

NOW Foods , C-1000
Verified Purchase
The quality of the ingredients is impressive. I ordered a large package and haven't regretted it at all. My whole family has been taking it for just two weeks, but the results were immediate: my skin became more even, and I feel much better. We take these vitamins along with vitamin E from the same company and are very happy with the results. Vitamin C plays important roles in our body, strengthens the immune system, and is a powerful antioxidant. A deficiency in this vitamin causes general malaise, weakness, drowsiness, and pale skin. Vitamin C doesn't accumulate in the body and is excreted in urine, so it requires regular supplementation. It's essential for the body, so I'm very happy I found these vitamins; we'll be ordering them regularly.

Excellent vitamin C, high quality ingredients, very convenient dosage, just take it once a day. Lasts a long time! Vitamin C is beneficial for supporting immunity, strengthening blood vessels, skin and bone health, and protecting against the harmful effects of free radicals. It promotes wound healing, aids in iron absorption, and can also relieve cold symptoms! Highly recommended!

I take NOW C-1000 regularly as a powerful antioxidant. I exercise regularly, so vitamin C is an essential part of my daily diet to support my immune system and aid recovery after exercise. Excellent quality: the tablets are medium-sized, easy to swallow, and have no acidic aftertaste. A time-tested product; I've been taking it for several years now. It helps me stay in shape and recover faster, especially during cold and flu season and during intense workouts.

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.

Vitamin C is one of the most important antioxidants for athletes: it supports immunity, helps recover from workouts, and reduces inflammation in the muscles.

The tablets are large, but they are easy to swallow. ✅ Pros: Supports immunity and recovery after workouts Reduces oxidative stress Large dosage, convenient form Now Foods quality is stable!
