Good

Before taking this drug, I had some symptoms of vitamin C deficiency in the body, in the form of bleeding gums, pale and dry skin, lethargy and increased fatigue. I ordered this drug not only to replenish the deficiency of vitamin C in my body, but also to strengthen immunity, since in the spring the coronavirus was already raging, and the benefits of vitamin C, zinc and vitamin D3 could be heard from almost every "iron".

Great

The quality, ingredients and protein of Now foods is trustful, size (mg), benefits, composition is good for immunity, acidity, potency, stomach, antioxidant maybe is enough. The package is ok. I'm not sure about the effects. There no taste. But I read that it's really good for healthy life, so that's the reason I'm using it.

One of the best

Verified purchase

I've bought NOW vitamins in the past and they didn't disappoint. This one was a no different as it is helping me keep my immune system up with the combination of zinc and D3. I don't love that their is citric acid in the ingredients but I'm not going to waste the bottle plus it's working for me and my family. The size of the pills are a bit big but I drink lots of water to swallow it. It has no taste, it's easy on my stomach (WHICH I LOVE) and I find the best quality to be just right.

NOW Foods C-1000 Zinc & D-3 is a convenient immune support supplement. Each capsule provides vitamin C, D3, and zinc for daily wellness. It’s easy to swallow, gentle on the stomach, and made by a trusted brand. I appreciate the simple formula that combines three essentials in one. Results are subtle but consistent. A great choice for boosting immunity, especially during seasonal changes.

imune booster

Verified purchase

The capsules seem big, but they go down easily. They are also easy to digest. I like that it's one capsule a day, but it packs high dosages of immune-boosting vitamins C and D. I prefer to go with NOW as a brand anytime I can because every single NOW product has been high-quality. This one did not disappoint either. I recommend.
