This d3 vitamins from 21st century is a worth buying products for its affordable price! This can last for a year already! The quality, the dosage and the size of the supplements is just enough yo take. This have a good benefits to your bones and the absorption of this product in our body is so effective!Try it to believe it!
I've tried a lot of vitamins and none of them work like this one. I feel so much better and energized, not to mention the burst of strength I get when I take it!
These are a great size and dosage. I don’t think “more is more” is necessarily true for vitamins, and this dosage is what my doc recommended for Sept - May. The size is super easy to take, I put them by my kettle to have every morning with my coffee.
First time I use 21 Century D3 tablets. Easy to swallow, as it is small in size. Come in plastic bottle brightly identified so it stands out if you have many pills in your medicine box. Good price too. 1000iu may be small dosage but should be enough if one is also out and about.
Good quality ingredient in a good size with correct dosage for immunity I don't get enough sun in a nice package to effect D deficiency good absorption for bones no taste I take with Omega 3 oil caps Also take Boswellia for pain with black pepper caps I Herb always has the best selection
