Benefits of Vitamin D – Part 1

• Vitamin D is a steroid vitamin.
• It is a group of fat-soluble prohormones.
• This encourages the absorption and metabolism of calcium and phosphorous.
• People who have normal quantities of exposure to sunlight do not require vitamin D supplements.
• The sunlight helps in sufficient vitamin D synthesis via the skin.
• Five kinds of vitamin D have been discovered.
• They are: D1, D2, D3, D4 and D5.
• The two forms that appear to affect humans maximum are Vitamins D2 and D3.
• Researchers of the University of Minnesota found that Vitamin D levels in the body in the beginning of the lowest calorie diet predict weight-loss success, suggesting some role of vitamin D in fat loss.
• Researchers from Boston University Medical School found that higher vitamin D levels in healthy people have a large influence on the genes which have been involved with several biologic pathways.

These are associated with Illnesses including:
– Cancer
– Autoimmune disorder
– Heart disease
– Infectious diseases

Vitamin D for humans is obtained from:
– Sun
– Food
– Supplements
• It is biologically inert and contains to endure two hydroxylation reactions to become active in the body.
• The active form of vitamin D found in the body is referred to as Calcitriol.
• Calcitriol promotes the calcium and phosphorus absorption.
• This is done from food that is present in gut and by calcium re-absorption inside the kidneys.
• This increases the flow of calcium within the bloodstream.
• This actually is needed for the conventional mineralization of bone and preventing hypocalcemic tetany.
• Hypocalcemic tetany can be a low calcium condition.
• Calcitriol also plays a key role in the repair of many organ systems.

In this condition the patient has:
– overactive neurological reflexes
– spasms with the extremities
– cramps of voice box
– spasms of the voice box

Various types of Vitamin D

• About 5 types of vitamin D are known of which vitamins D2 and D3 are the major forms for humans.
• They are known collectively as calciferol.

Vitamin D1
• It is a molecular compound of ergocalciferol with lumisterol.

Vitamin D2
• It is a compound of ergocalciferol
• It’s produced by reacting to sunlight by:
– Invertebrates
– Fungus
– Plants
• Humans and other vertebrates tend not to produce vitamin D2.
• There is no reason known as to what vitamin D2 does in invertebrates.
• We realize that ergosterol is a great absorb-er of ultraviolet light. This can damage:
– DNA
– RNA
– Protein
• Consequently, many scientists consider it to act as sunscreen which can protect organisms from sunlight damage.
• Temperate regions are typical regions away from tropics and arctic circles.
• A human requires 10-15 minutes of exposure to sun at least a week.
• Sun exposure should be on the face, arms, hands, or back without sunscreen with over 3 UV index for adequate levels of vitamin D3.
• Longer exposure leads to the extra vitamin supply which is being degraded as soon as it’s generated.

Vitamin D3
• It is a compound of cholecalciferol.
• Vitamin D3 is created in the skin when 7-dehydrocholesterol responds to ultraviolet illumination at 270-300 nm wavelengths peak.
• Vitamin D3 production occurs between 295-297 nm.
• It’s only when the UV index is greater than 3 that particular UVB wavelengths are mixed together.
A UV index greater than 3 occurs:
– each day in the tropics
– each day during spring
– each day of summer
– parts of autumn in temperate areas
– hardly ever at all in the arctic circles.
