Bone and Immune Health Vitamin Supplement Supports Bone Health Plus Immune and Cardiovascular Wellness Promotes Calcium Absorption in the Body Science-Backed Quality Since 1969 Gluten Free Non-GMO Do you get enough of the powerhouse Sunshine Vitamin? The body manufactures some vitamin D on its own when it is exposed to sunlight—hence the nickname—but for people living in the northern latitudes where wintertime sun exposure is limited, the body's natural vitamin D production may not be enough. Additionally, our ability to produce vitamin D diminishes with age. According to the National Institutes of Health, most people in the United States consume less than recommended amounts of vitamin D.

Excellent! choice for D vitamins

I selected this product based on the price. it's affordable. I have deficiency in D vitamins so this gives me energy and it's a good deal. it also boost my immune system against sickness. the capsules are easy to swallow. I read also that it compliments biotin supplement. vitamin D capsule is essential for good health. it's amount of capsules is sufficient.

Great

Small size of capsule in portable package bottle, and nice taste, easy to dissolve in mouth. It can boost D3 deficiency, and good for immunity and absorption. One or two dosage per day is advisable if low in D3 level as ingredient are quite fit for us to take daily. In term of Quality, it is really effective. If cant get Natural Sun, pls go for it.

I ordered this almost accidentally while replacing several household items at once, so expectations were basically nonexistent. It turned out to be the purchase I appreciated most from that order. Everything feels accessible, thoughtfully proportioned, and easy to keep organized. Funny how the things you research least sometimes work out best.

Great for winter

I already finished the pack and in combination with zinc and vitamin C, I can say that I stayed healthy and strong this winter, even though many of the people around me were sick. For example, my sister had a flu, and we had sat together the night before she actually got ill. She had a fever for a couple of days and felt so weak; I ended up with a runny nose and a sore throat for a day or two. That's it. So, I really think that supplements do help.

I've been using those for a while now, and I can't complain. I like their small size, and though I don't know for sure if they work, I definitely haven't noticed any negative side effects.
