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
