Love the convenience

This type of vitamin is hard to 'review'. It is a preventative type of vitamin. But - one thing is for sure - I love the convenience of ordering this product and knowing the cost is reasonable!

C-1000

I really like the 21 Century prolonged release C-1000 pills. even though they are large, they have a slick surface, making easier to swallow them. I take 5000 mgs. daily. I only have to take them once a day because of the prolonged release. They are also resonably priced. Good buy for better health.
