I am now able to leap tall buildings in a single bound, can see through rock and can run faster than a speeding bullet! Seriously, here on the Oregon coast most of us simply do not get enough sunshine to keep our D levels up where they should be, so the doc recommended this supplement. My blood tests are normal now. Flavor? they ask. One swallows the tiny gel capsules. Do not chew them!

Excellent !

large size, proper packaging, very good price. it helps me resolve my deficiency in vitamin D and to boost my immunity during flu seasons, I even take it if there is a good sun outside because I avoid long periods of sunlight due to sensitive skin.I used to take the 250mcg before but this dosage is good for me since I take it more often. It has an ok taste and the product is of good quality. Would defintely recommend it

Excellent Product and a Great Value!!!

As we all know, we have daily requirements of all nutrients(vitamins, minerals, trace minerals, amino acids and healthy fats) that need to be taken in enough quantities each day. The preferable source is food or through sun reaction with skin(in case of vitamin D3) . The form of the nutrients has to be the active form, as well as their most absorbable form. However, in nowadays diet people hardly get enough of the daily requirements of all those nutrients, and also in the colder months it's nearly impossible to get enough vitamin D3. That's why in addition to nutrient dense diet we need to supplement. That's why I ordered this supplement to make sure I'm getting enough for the winter to protect my immune system and bone health. I take 2 capsules a day together with ... MoreAs we all know, we have daily requirements of all nutrients(vitamins, minerals, trace minerals, amino acids and healthy fats) that need to be taken in enough quantities each day.

I take 2 capsules a day together with vitamin K2(mk-7) 100mcg as the latter is important for pulling calcium out of the soft tissues and putting it where it belongs, in the bone, so both of these vitamins work perfectly together. I'm happy with quality, quantity and price and I would buy again!

Have been taking these vitamins since I was diagnosed with osteopenia, which has actually been reversed slightly... something I didn't think would happen. I can't credit it solely to these vitamins but I ain't complaining. I particularly like the flip-top that makes it easy to get one out each morning.

The Vitamin D3 is important for my immune system. I spend a lot of time indoors, so my body gets too less sunlight to create vitamin D3 itself. I'm very happy with this Vitamin D3 without artificial coloring or too much additives & preservatives. And for an Awesome Price! This Supplement is also available in a lower dose: 400iu and 1000iu and a smaller amount: 110 tablets. Be careful not to overdose your vitamin D3, especially with Lyme Disease.

Tampered seal, money lost!
19 September 2022

The seal was tampered and they tried to seal it again by heating the seal. I won't use it as I don't know if the pills are expired or even fake! I'm so upset there is no way to rate the seller instead of the product. I never had an issue before with the 21st Century, this is unacceptable and from my point of view, this is the responsibility of the seller, not the brand. I lost this money, as I threw it in the garbage. Never again will buy from this seller
