THE OLDEST HORMONE ON EARTH: VITAMINE D

As we soak in rays of sunshine, our thoughts may turn to vitamin D — because we probably know it has something to do with the sun. But do we actually know what it is?

I feel that I use sun light as a wonderful remedy which is cure and repair cell of my entire body within a minute, I assume that I drink vitamin D through my skin and I really mean, That we all humans are actually light-eaters. Because vitamine D get energized our body.

We humans are kindly capable of photosynthesis, and we use it to produce what scientists believe to be the oldest hormone that has ever existed on earth. It’s vitamin D, and it’s been around 750 million years.

There are some questions arise in our mind,

What is Vitamin D?

Vitamine D is a hormone produced by the kidneys that helps to control the absorption of calcium in the blood and is basic for development of strong bones.

It is actually a hormone significantly than vitamine.

It is required to absorb calcium from gut into bloodstream.

Essentially produced in skin in response to sunlight and is also absorbed from food eaten as part of a healthy balanced diet.

Both liver and kidneys convert Vitamine D into active hormone, which is know as Calcitriol.

Active Vitamine D support to increase amonut of calcium in gut can absorb from eaten food into bloodstream and also prevents calcium loss from kidneys.

Vitamine D modofies activity of bone cells and is also important for the formation of new bone of children and adults.

How is Vitamin D controller?

Calcium concentration fall in bloodstream is detected by parathyroid glans, which produced parathyroid hormone.

parathyroid hormone increases enzyme activity , that produced activr Vitamine D., this increase in concentration of calcium together with Vitamine D meal back to the parathyroid gland to stop more parathyroid hormone release.

production of Vitamine D is also directly regulated by Calcium , Phosphate and Calcitroil.

What arise when we take too little Vitamin D?

Vitamine D deficiency is very common now a days , proabably due to life style change during lockdowns and present pandemic condition, lack of sun exposure. We dont go outside and most of time locked ourself inside houses.

If you take low levels of Vitamine D you are unable to maintain an sufficient concentration of calcium in your blood for bone growth.

This cause Rickets in children and Osteomalacia in adults.

Appearance of Vitamine D as a regulator of other functions all over the body get appear, it has been suggested that lack of Vitamine D is associated to an inability to fight infections completely, muscles weakness, fatigue and devlopment of diabetes, cancers, multiple sclerosis, depression, heart disease, high blood pressure and stroke, even through direct relevance and mechanisms hidden these responses remain unkown.

Sunlight is essential to the body’s ability to absorb calcium from the food you are eating. Make sure you recieve adequate Vitamine D every day throught sunlight. About fifteen to twenty minutes of sun on the face and hands is usually enough for most of us.

Scientists are not assured exactly why vitamin D developed, but one theory is that it functioned as a kind of early sunscreen. It also helped with another stumbling block on the evolutionary road out of the water and onto land: calcium.

Active from calcium-rich environment of sea to dry land conferred certain problems, especially getting plenty of it, and it just so happens that the production of vitamin D in the body changes the ability of calcium to get into each cell. This probably made more of the calcium already present in the body usable.

Enough comparable Noble phytoplankton, when rays from the sun strike your body, you (along with amphibians, reptiles, all bird species and most mammals) “photosynthesize” vitamin D allow to body to metabolize calcium. It is not actually the same process by which plants create generate from sunlight, but it is as similar form of photosynthesis — the use of light to synthesize a chemical.

It is very sad but true, “The modern understanding of vitamin D begins with a bunch of researchers torturing puppies in the name of science” Yes, really. Aren’t you glad you started down this sunny rabbit hole?

In 1919, scientist Edward Mellanby profitably induced rickets in puppies by feeding them only bread and low-fat milk, noting that the resulting bone imaging and physical presence of the dogs mimicked that of children suffering from rickets. Enrich the diets of the teeny puppers with yeast and orange juice (for B vitamins and scurvy-prevention, respectively) did nothing to stave off the bone disease; however, supplementation with both butterfat and cod liver oil did the trick. And with that, rickets was officially kick out as a disease of deficiency. And where there’s a deficiency, so, too, must there be a vitamin to be deficient in.

The term vitamin D refers to a group of fat-soluble steroids with a special “broken ring” formation. The shape of the compound is notable because it helps the body absorb critical nutrients such as calcium, iron, magnesium, phosphorus and zinc through the gut wall.

This is all well and good, and explains in part why we add vitamin D to calcium-rich milk.

So, take as mor as possible Vitamin D through sunlight because health (outer and inner)is more important than wealth and sun is the best medicine to energized your body.
