Item came on time and arrived in good condition. First purchase so will need to try it for a while to know if it is effective.

Taking two a day - one at breakfast & one at dinner for immune suport. I like this tablet form much better than the oil capsules. Can't just depend on the sun and milk for vitamin D! Excellent quality. 21st Century is a brand that I trust!

My child can’t swallow soft gel capsules so I tried this tablet form supplement. Easy to dissolve and the dosage is what I needed for my teenager!

These vitamins are what we needed , here in Ireland the sun is little and you must onlydecided to receive these vitamins I noticed that it normalized the structure of the nails, grow faster and do not break...the box is very convenient, they arrive for a long time, it's great that it also contains calcium because without it it is not absorbed in the body, it's great

Great product, the package very well packed, I always buy the product.

Satisfy my needs and help me to keep on my health

I really liked it. It is a must-use during these time effect is very good

Just like it , better than being out in the sun

Great product and easy to swallow. They’re nice and small too. No side effects for me and a great addition to my vitamins.

My internist prefers that I take tablets, versus the gelcaps or liquidgels. They are hard to find! We have multiple family members taking these currently (teens to adults) and all agree that they're easy to swallow. Have repurchased, and am quite happy with them.
