Great price point!

Vitamin C though one of the more common vitamins can still be confusing to buy. To increase profits many companies prepackage and add sugar and dye to vitamin c crystals. We love Natural Factors Vitamin C Crystals because they only contain Vitamin C! And being able to buy in bulk gives us no excuse to not be a healthy family. For a cold, try having it with warm water and local honey to help you sleep and feel better in the morning. As far as Natural Factors, they are a great Canadian company with clean ingredients and very reasonable prices.

powerful probiotics

Have tried other probiotics, including one designed for women but this one is most effective. If I avoid too much bread, I only need to take a capsule once or twice a week. So ,not really expensive to use.


Love these, healthier choice

Apple cider vinegar

I've used it for years. Good product

As effective as ever

I took this over 15 yrs. ago for a broke pelvis. Took it for years. Stopped as it didn’t need it anylonger. Recently my inflammatory markers were slighlly elevated, and m ower back started to ache. So I restarted it and yes after 5 days it’s back to normal. The company was the firs to come up with NEM and it’s still going strong.
