Easy on stomach & great for respiratory/immunity issues. (Dr. advised not for everyday use if you have a history of kidney stones.)

GOOD PRODUCT.!!
I have been using this product for numerous numerous years since it was placed on the shelf for supplement products. The tablet itself is easy for me to swallow and the taste is good. I like the idea that it helps with immune support (which we need help with). I even give my husband a tablet daily. I will continue to take this product.

Best vit c
My favorite vitamin c. Have been using these for years and believe they have prevented a lot of colds I worked in retail for years and was always in close contact with people. I would never be sick. Now I volunteer and am in contact with a lot of people and staying very healthy.

Great Quality Vitamins That Really Make a Difference!
I’ve been taking this vitamin supplement for a while now, and I can definitely feel the benefits. The quality is excellent, the capsules are easy to take, and there’s no unpleasant aftertaste. I’ve noticed an improvement in my overall energy and well-being since starting them. It’s also reassuring to know the ingredients are clearly listed and well-balanced. A solid, reliable supplement that delivers what it promises!
