Why You Need More D:
- Vitamin D is essential for helping calcium in your GI tract—from the food you eat—get into your bloodstream.
- Your bone health depends on it.
- Vitamin D also supports brain and nerve health by regulating the hormones serotonin and dopamine.
- Vitamin D improves your immune function because many of your immune cells have vitamin D receptors to help regulate the chemical processes
Why You Probably Don’t Have Enough:[i]
- Number one reason worldwide—a lack of adequate sunlight. Weak light, sun from overcast or winter skies is not strong enough. If most of your skin is covered, you are not getting enough.
- A sunscreen with SPF 30 is enough to block 95% of the vitamin D your skin might make.
- No fish. People who skip the fatty fish—like salmon, cod, tuna and anchovies—rarely get enough from their diets.
- Your other eating habits—if you are shunning red meat, liver, and egg yolks in addition to fatty fish, you are skipping the best sources of vitamin D.
- Mislabeled, misunderstood sources. Milk often has less than 80% of the vitamin D the label claims.[ii] Farm raised salmon has barely a third as much vitamin D as wild caught, and other fish have even less.
- Body mass matters. The larger you are, the harder it is to make enough vitamin D naturally. Overweight people are especially likely to be deficient.
- A dark-skinned person requires 5 times as much sunlight to make vitamin D as a light-skinned person.
- Medicines can interfere, especially anti-convulsants, but several others as well.
- People with difficulty absorbing fat may be low on Vitamin D. This can include people who have had a their gall bladder removed, or digestive illnesses.
- A number of granuloma-forming diseases interfere with vitamin D. These include chronic lung diseases, tuberculosis, lymphomas, and thyroid problems
Why You Need Vitamin K[iii]
- Vitamin K is needed to make four proteins that cause clotting and prevent excessive bleeding.
- It supports adequate calcium absorption for bone density.
- It prevents excess calcium from circulating in bloodstream where it can build up in arteries.
- It helps regulate cell growth
- Plus, stronger levels of K are associated with better cardiovascular health
Why You May Not Have Enough:
- Absolute deficiency in adults who get enough calories is rare, but many people could use more to maintain ideal levels.[iv]
- The main dietary sources are dark leafy greens; some people do not eat enough. You would need a cup or more of rich sources per day. Every day.
- The most common cause for low Vitamin K levels in adults is medication, particularly warfarin. See a doctor is you are on anti-coagulants because you will need medical guidance to adjust prescription drug levels and other dietary intakes. Adding this supplement may not be suitable for you.
