so let’s talk about the evolution or the  origin of vitamin d it’s quite fascinating phytoplankton has been on this planet for about i  don’t know 750 million years it’s been unchanged and phytoplankton exposes itself to sunlight  and makes vitamin d now there’s a compound in the environment called squalene it’s an ancient  molecule it’s an oil that lives between rocks by the seashore plants make it animals make  it but it’s a precursor to cholesterol and steroid hormones now i’m not going to get  into the complex biochemistry of this but all you need to know is that that’s like  the raw material that eventually turns into vitamin d because vitamin d comes from cholesterol  now originally phytoplankton uses certain things from the sun’s rays to create different  chemicals within the living organism itself and one of the problems way back on this planet  is that we didn’t have an ozone layer so back then without the protection of the ozone layer there  was quite a bit of damage that was created from this uv radiation and so organisms experienced dna  damage so somehow vitamin d was created to protect the organisms from developing damage from this  uv radiation from the sun and so as time went on this mechanism was transferred up the food chain  first into fatty fish as you know salmon has a lot of vitamin d and so does cod liver oil and so life  forms took advantage of a very abundant mineral called calcium and so they use calcium for  neuromuscular communication cellular communication using calcium in their skeletal structure  to make it very very hard like cement as well as an electrolyte in the communication  of nerves and the contraction and relaxation of muscles as you know if you don’t have enough  calcium you get a lot of muscle spasms and this is why in our own bodies  if you’re deficient in calcium you’re going to get low back tightness spasm and  pain and so one of the most important functions in both animals and humans in relationship to vitamin  d is calcium absorption and the utilization of calcium in the small intestine vitamin d helps  absorb calcium by 20 times so without that vitamin d you’re not going to absorb calcium and you can  have a lot of problems osteoporosis osteopenia osteomalacia which is your bones become soft and  if a pregnant mother is deficient in vitamin d that child is going to be deficient in calcium  and potentially could have scoliosis flat feet hunchback swayback and even rickets in which the  legs are kind of bowed and so i’ve done a lot of videos on vitamin d in relationship to your  immune system acting as an anti-inflammatory helping prevent autoimmune diseases but the  big function of vitamin d is in what it does to calcium and so if you’re deficient in vitamin d  your bones aren’t going to work calcium will also accumulate on the inside of your arteries in your  joints is arthritis it can even increase risk of heart attacks and vitamin d also works with  vitamin k2 as well we don’t want to forget that and so just as photosynthesis occurs in plants we  also have a type of photosynthesis that converts the sun not into energy in our bodies but into  vitamin d which actually is not really a vitamin it’s a hormone now if you haven’t seen my other  videos in vitamin d i put them up right here check them out hey before you go real quick i have  a course entitled how to bulletproof your immune system it’s a free course i want you to take it  and here’s why here’s you here is your environment everyone is focused on this over  here avoiding your environment but what about here what about strengthening  your immune system that’s what’s missing this course will show you how to bulletproof  yourself and so you can tolerate and resist your environment much better by strengthening  your own immune system i put a link down in the description right down below  check it out and get signed up today
