Was deficient in Vitamin D3 for many years and i talked to my doctor many times but only when I went to a Immunologist he raised amount and added K2. As for now I have so much energy and no more mood swing .<br />Also, my husband has better sleep at night .

I especially like that the two vitamins are at a good level with each other. I read the data about D3&K2 boosting the immune system. So far, so good!

Great deal. Same as my prescription strength Vitamin D supplements plus Vitamin K. No prescription needed. Vitamin D helps me with Depression and many studies say it is protects against the cytokine related inflammatory response of Covid 19.

Has helped me with calcium absorption. Noticeably stronger teeth with less looseness. Loose teeth is osteoporosis of the jaw. From what I understand Vit D3 helps calcium be absorbed by the gut then Vit K2 transports it to the bones and teeth. Without Vit K the calcium can be deposited in soft tissue (which isn’t good) instead of bones and teeth. Vit K also helps remove calcium deposits in the arteries. Pretty crucial and seemingly overlooked vitamin from what I’ve found.

I didn’t notice a difference until I ran out. I’ve been on prescription vitamin D once before for severe aches and pains due to low levels of vitamin D. I was out for about 10 days when I noticed the muscle cramps and aches returning. Even my sleep was off. These work perfectly. I won’t let myself go without them ever again.

I like the size of these pills, easy to swallow, no awful smell. Great deal. I like the amount per serving. Didn’t notice any side effects, feel better in my joints and bones. Good combo of vitamin D and K.
