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.

my second purchase of this product. the quality, size, dosage, ingredient and taste are acceptable for me, and now i bought this again for my husband, since most of the time he stays indoors because of his job. he doesnt have much sun exposure, might lead to vitamin d deficiency. i hope it will help with his immunity. package arrived earlier. i highly recommend this product to my friends. please give a thumbs up if you find my review helpful.thank you iherb!.

I and my mother have been taking this vitD for several years. I take this vitamin D3 4000 iu and my mother takes this vitamin D3 5000 iu daily. She is 94. The tablets are small and easy to swallow. Our blood tests levels are great. I am very grateful for this product, because it is high quality and great price. Thank you iherb!
