Our body produces vitamin D when the ultraviolet rays of the sun interact with the oils of our body. This solar radiation not only improves our moods after the gloomy dark cloudy days here in the Northwest, but it does change some biochemistry systemically that impacts many areas of our well being.
When we get adequate sun exposure, we rarely need added vitamin D as a supplement. Challenges to getting enough vitamin D include living in the Northwest where we don’t get enough sunlight to keep up with our body’s requirements.
Those of us who’s ancestors come from the north country where sun exposure is limited, we see lighter colored skin, as the body tends to produce less pigment, allowing more of the ultraviolet rays through.
If your ancestors come from Areas of extreme sun exposure, chances are you’ll have greater amounts of pigmentation and darker skin, creating a greater need for sun exposure or nutritional support like a good fish liver oil. When you consider your heritage and skin color, that can be an indicator of the amount of sun exposure required.
Calcium and phosphorous levels are dependent on vitamin D. Since both minerals are required for bone and tooth strength, the addition of vitamin D to milk sounds like a good idea. Unfortunately, pasteurization destroys a critical enzyme responsible for absorbing these minerals. This renders commercial milk rather useless when it comes to providing vitamin D and critical minerals to the body.
Since Vitamin D increases uptake of calcium into the blood, we have to be aware of another mechanism, required to deliver calcium into the tissues. This involves vitamin F, or poly-unsaturated fatty acids. Flax oil is just one example of an oil that delivers vitamin F to the system. Too much vitamin D without enough F will deplete calcium from your tissues, and overload the blood. Elevated calcium in the blood can create high blood pressure and other calcium problems like kidney stones and bone spurs.
There’s great concern about the sun creating skin cancer. The sun isn’t dangerous to the skin if there is enough vitamin F and calcium in the diet to maintain proper tissue stores. When we see hives and welts on the skin from sun exposure, that’s a very strong sign of insufficient poly-unsaturated oils.
Many neurotransmitters our body makes to maintain chemical balance are vitamin D dependent. Endorphins are morphine like substances which improve pain tolerance. Many times I’ve seen reduction in chronic pain when vitamin D is increased. If you tend to have a very low pain tolerance, consider the possibility you’re vitamin D deficient.
Serotonin is created in our gut, and is highly dependent on vitamin D. This neurotransmitter helps control, insulin release, mood, appetite, sleep, social behavior, and brain development in the womb. Instead of relying on SSRI drugs, it makes sense to first evaluate vitamin D status.
Dopamine is a neurotransmitter which helps protect against depression, (much like serotonin does). Although this requires vitamin A to be formed, vitamin D is required to regulate production.
Endocannabinoids are key regulators of cortisol production, and mediated by vitamin D and arachidonic acid, made in the liver from poly-unsaturated fatty acids. They’ve become more understood in their role of dealing with anxiety and burnout as investigation of marijuana for medicinal purposes has stimulated more research. Our liver must be healthy to make arachidonic acid out of dietary unsaturated fats. With liver problems or vitamin D deficiency, we see people, who are stressed, anxious, and dealing with issues of feeling self defeated, becoming addicted to marijuana because they can’t produce their own endocannabinoids.
