Five years ago, there were several articles on GIM about the importance of vitamin D3+, and they made a believer out of me. So when I saw a doctor then and said I was taking 5,000 IU daily, he asked why because he thought vitamin D was only for bones! I explained briefly about the vital role in the immune system. Hopefully, he did some homework reading on vitamin D.

How Vitamin D3 Works
1. Vitamin D was discovered in 1920 where its importance in our bodies was realized in discovering a way to cure rickets, a painful bone disease in children (2)
2. Vitamin D fortified foods began within a decade, making rickets rare in the US (2)
3. Vitamins are defined as an essential nutrient that your body cannot produce on its own and must acquire from the diet - Vitamin D is not actually a vitamin, but a hormone, which is a chemical that regulates body physiology. (1)
a. Your skin makes vitamin D when exposed to sunlights, so it does not need to acquire it from food if adequate sunlight is available (2)
i. The only natural foods that contain vitamin D are fish and egg yolks (2)
What Does Vitamin D Do?
1. We are discovering more and more ways that the body utilized vitamin D as time goes on
a. Vitamin D receptors, proteins that bind to vitamin D, exists in many of the body’s tissues, including the heart, muscles, endocrine glands, prostate and many others. (2)
2. Bone health - vitamin D is essential for our bodies to be able to absorb calcium. Without enough vitamin D, the body absorbs only 10-15% of dietary calcium, versus 30-40% when our vitamin D levels are normal.
How to Get Enough Vitamin D
Now that we understand how important vitamin D is in our bodies, and how likely it is that we do not have enough, how do we get more?
1. Sunlight - It can be a good idea to first spend a bit of time in the sun before applying sunscreen
a. spend 10-15 minutes three times per week without sunscreen on. This may be enough to prevent deficiencies (5)
2. Fatty fish, such as salmon, tuna and mackerel, and egg yolks (5)
3. Fortified foods: Many foods have been fortified with vitamin D, so look for this at your grocery store. Such foods include some milks, yogurts, orange juices and cereals (2)
4. Mushroom trick: mushrooms are a great source of natural vitamin D
a. Exposing mushrooms to sunlight prior to eating them will ramp up their vitamin D levels! So sit them on your window sill or backyard prior to adding them to your food (6)
5. UV Lamps
a. They are similar to tanning beds, but not identical. They carry the same skin-cancer risk as the sun or tanning beds, so be careful not to overdo it. These are a great option for those who live where there is little access to direct sunlight (8)
6. Supplementation: Last is supplementation. It is best to obtain some sunlight and concentrate on adding additional vitamin D in your diet. That being said, if you believe you are lacking vitamin D you can always buy supplements. Total recommended intake can vary from about 200 IU to 400 IU per day, including what you get from diet and sunlight. (5)

Dr. James Dowd discusses the role vitamin D plays in brain development and related conditions. Find out the role vitamin D plays early in an infants development and how that might be connected to some common conditions. Are these common conditions vitamin d related?
Interviewer: Doctor, can you talk more about fetal development and specifically early brain function and vitamin D's role in that?
Dr. Dowd: So, early brain function in an infant, a lot of things going on in an infants brain. Starting probably in the last trimester of pregnancy and then in the first 18 months to two years of life, okay. Again, remember in those 18 months or two years, what's happening? They're learning to talk. They’re learning to walk. They're developing emotional attachments to things. They’re communicating with voice. They're communicating with language. They’re communicating with emotions and they are communicating physically with their environment. And all of this means the brain is changing very rapidly to acquire all of this new skills in very early childhood and in late fetal development. Growth factors are very important in putting all these connections together particularly nerve growth factor. And what we know in studies is that nerve growth factor is tied directly to vitamin D and that vitamin D induces the expression of nerve growth factor. And in the absence of vitamin D, nerve growth factor levels are lower. And we notice form a number of different annual models where you can induce an injury and then see how well it heals in the presence to the absence of vitamin D. There's even behavioral models because you think about, you know we think about Attention Deficit Disorder and then there's autism and there's schizophrenia and these maybe a spectrum of disorders that relate to abnormal brain development. Attention Deficit, the worst of Attention Deficit Disorder being the least severe of these and schizophrenia and autism being the most severe of these are clinical diseases.But we believe that these are developmental brain abnormalities. They're not some exposed to something late. They were probably something went to ride during brain development, in during fetal development or in the early 18 months after confinement or birth. And so it's anatomical geographical change in the brain that is occurring. And we know that vitamin D is important in the migration of neurons to different areas of the brain. We know that vitamin D is important in nerve growth factor secretion and so during brain development,vitamin D is a key player among other anabolic hormones, okay? Sex hormones from the mother and the placenta. Growth hormones from the mother and the placenta like instant related growth factors and some other means. All work in concert with vitamin D to orchestrate brain development. And the brain is sort of like a sculpture, so you start out with all of these neurons that re just kinda vibrating and you sculpted out behavior. It's like carving out walking.It's like carving out different behaviors and that's how learning happens. And so actually cells, brain cells, you carry with the whole access of brain cells and you actually, some brain cells die to create the behavior. One brain cell neuron will die allowing the other neuron to flourish and that creates the behavior that this pattern, okay. And vitamin D is absolutely critical in not only helping the one grow that survives but also turning off the one that you don't want to be there. And you can almost see how. Okay, if some neurons that were supposed to be turned off are still on, how that might contribute to a clinical diseases like autism and schizophrenia? Or how when that was supposed to flower and flourish in the absence of the right soup of growth hormones including the vitamin D didn't flourish? And you can see how this might affect a clinical syndrome later on. So it's important for protecting your brain from injury and repair from injury. It's important for normal development of the brain. It's important for acquiring and retaining memory and cognition.These are key features of brain function during development and they manifest problems early, it can manifest later in the form of dementia and other diseases. Parkinson's disease for example.
Vitamin K | Fat Burning Partner to Vitamin D - Thomas DeLauer Thomas DeLauer
Published on Feb 28, 2017
We hear all about this all the time, but is it really true? Does wimpy old vitamin D NEED Vitamin K? http://www.ThomasDeLauer.com
Do you need vitamin k with vitamin d?
A hormone, not an actual vitamin, that your skin makes when exposed to sunlight, so it does not need to acquire it from food if adequate sunlight is available
The only natural foods that contain vitamin D are fish and egg yolks
Most of us are deficient in vitamin D as we do not spend much time outdoors. Additionally, where we live can limit our access to vitamin D - if you live below 37 degrees south or above 37 degrees north you do not have access to sufficient sunlight except during the summer months. (
This line of latitude crosses below Colorado, Utah and Kansas, so the majority of us in the US require additional dietary vitamin D throughout the year even if we spend time outdoors
Sunscreen and skin pigmentation can also act as barriers to vitamin D absorption
What Does Vitamin D Do?
Reduces belly fat
Of all the places to lose fat, the middle of our bodies is usually the hardest and the most important, both for looking lean and for being healthy.
Waist-to-hip ratio is a factor in your risk for heart disease and type 2 diabetes
Research bomb: A study published in the journal of Clinical Nutrition had 23 overweight participants who all went through a 12-week resistance training program. Half of them took 4,000 IU’s of vitamin D while the others received a placebo. While both groups lost the same amount of fat, the group that took the vitamin D supplements were more likely to have lowered their waist-to-hip ratio to a greater extent when compared to the placebo group. (3)
Hormone Regulation and Bone Health
The parathyroid glands, located in your neck, release parathyroid hormone.
Parathyroid hormone regulates the calcium in your body:
When the level of calcium in your blood is low, your parathyroid releases PTH. PTH signals for calcium to be leeched from bones and released into the blood, while also telling your kidneys to create more bioavailable vitamin D. This form of active vitamin D tells your gut to absorb more calcium, as long as you have sufficient vitamin D available.
When you are deficient in vitamin D, your body will not absorb enough calcium from your diet and too much calcium will be taken from the bones to be available in the blood.
Calcium plays more roles than just bone health - it is crucial for proper functioning of your nervous and muscular systems, so the body is able to take calcium from the bones to perform other functions.
Vitamin K is helpful in blood clotting and bone strength. May also help to prevent heart disease, prostate cancer and Alzheimer’s
Vitamin K2 and vitamin D3 work together to strengthen bones through their impact on calcium
While vitamin D3 essentially regulates how much calcium is absorbed in the diet, vitamin K2 tells the calcium where to go, directing it to bones rather than soft tissues. When calcium attaches to arteries, known as hardening of the arteries, it can lead to cardiovascular complications.
Without vitamin K2, the calcium absorbed will not go towards strengthening your bones, and thus vitamin K2 is crucial in the functioning of vitamin D3.
Vitamin K2 comes from meats, eggs, hard cheeses and insects. Many people are also deficient in vitamin K2.
Diet and Supplementation
The best way to stay healthy is to eat a balanced diet full of leafy greens, fruits, veggies and lean proteins. This is how we can be sure we are obtaining a full range of vitamins and minerals.
Vitamin D3 is one vitamin/hormone that we often have to supplement. If your supplement vitamin D3, be sure to obtain enough vitamin K2, either through a diet with meats and eggs, or through supplementation as well. Also be sure to obtain calcium through your diet, such as yogurt, leafy greens and legumes, or through supplementation. If you do not have all three in your diet, you may be doing more harm than good.

Vitamin D Deficiency: 6 Symptoms to Watch Out For - Dr Alan Mandell, DC motivationaldoc
Published on Jan 26, 2018
Millions of people worldwide are deficient in Vitamin D and never know it until sickness strikes. Our immune system is directly affected. The Recommended Dietary Allowance (RDA) for adults is 600 international units (IU) of vitamin D a day. That goes up to 800 IU a day for those older than age 70. To meet this level, choose foods that are rich in vitamin D. For example, choose fortified foods, such as milk and yogurt, and fatty fish, such as salmon, trout, tuna and halibut. Vegans can get their vitamin D from mushrooms, fortified soy milk, fortified breakfast cereals, almond milk, and tofu, If you're concerned about whether you're getting enough vitamin D, talk to your doctor about your diet and whether a vitamin supplement might benefit you.
