Vitamin D is fat-soluble; its absobtion depends on the Gut’s ability to absorb dietary fats. Not absorbed completely leads to liver diseases like cystic fibrosis, ulcerative colitis, celiac disease, and Crohn’s disease. It is not excreted in the urine.

How is Vitamin D Absorbed?

Doctors recommend absorbing sunlight every morning, which gives minerals essential for maintaining bone mass and density. When exposed to sunlight, it absorbs into the fats through the skin, so when there is no sunlight, it circulates to the human body.

However, poor vitamin D leads to gestational diabetes (diabetes diagnosed for the first time during pregnancy). Treating vitamin D deficiency may also reduce the risk of asymptomatic bacterial vaginosis (i.e. absence of symptoms of vaginal discharge and odour) in pregnant women. However, the research found no links between vitamin D supplementation and avoiding bacterial vaginosis.

Moreover, the vitamin D adults consume from their diets is usually less than what’s recommended. Exposure to sunlight can make up for the difference.

Vitamin D and Heart Health

Years ago, observational studies revealed that those with higher blood levels of vitamin D had lower incidences of heart disease, which gave rise to the hypothesis that an increase in vitamin D consumption may enhance heart health.

Researchers voted for randomized, controlled studies, including VITAL, to determine if vitamin D was the cause of this impact or only a risk marker. More than 25,000 participants participated in the VITAL study between 2011 and 2013, which discovered that using high-dose vitamin D supplements did not prevent heart health. Additionally they carried a meta-analysis on this subject. following evaluation of 21 randomised studies pertaining to vitamin D and heart health.

Vitamin D for Bone Health

Vitamin D is essential for bone health. Muscle cramps and bone or joint pain may be more common in those who have extremely low blood levels of vitamin D.

Insufficient: Levels between 30 to 50 nmol/l or 12 to 20 ng/ml

Sufficient: Levels between 50 to 125 nmol/l or 20 to 5 ng/ml

High: Levels more than 125 nmol/l or 50 ng/ml

In some diabetic patients, an injury sometimes takes a longer time to heal because of this deficiency.

Sources of vitamin D

The major source of vitamin D is the Sun. Our body produces vitamin D when exposed to sunlight. Our kidney processes the Vitamin and activates it into 1, 25 dihydroxy Vitamin D. Exposure to the sun is easier in places where you get to see the sun often.

The summer season provides an ample amount of vitamin D, but for that, your skin needs to come in direct contact with UV rays produced by the sun. Sunscreen limits the reach of UV rays to your skin and acts as a barrier between your skin and the sun.

You can also gain the required vitamin d hydroxy 25 from Vitamin D-rich food. Oily fish, red meat, liver, egg yolk, mushroom, and cheese are considered good sources of vitamin d.

It plays a significant role in maintaining immune and bone health. Vitamin d hydroxy 25 stimulates intestinal calcium absorption and helps to maintain proper calcium and phosphorus levels in the blood, which is essential for healthy bone density.

 Vitamin D hydroxy 25 develops the auto-immune system against diseases like diabetes, asthma, and arthritis. Daily vitamin d needs vary with Age. Pregnant women and breastfeeding moms are at higher risk of deficiency.

Vitamin D Test for Detection
