Vitamin D Deficiency and Its Effects

Not obtaining enough vitamin D can cause rickets in kids, leading to misshapen bones. Adults can have osteomalacia, causing bone discomfort and weak muscles. If this carries on for a long time, it might develop to osteoporosis. This makes bones brittle and easy to break.

Low levels of vitamin D can also make elderly persons more susceptible to fall and fracture their bones. Falls are a major factor for injuries and impairments in elderly. Eating meals containing vitamin D, getting sunlight, and taking supplements can minimize these risks.

Monitoring Vitamin D Levels

The easiest approach to assess if you have adequate vitamin D is with a blood test for 25-hydroxyvitamin D. Aim for blood levels over 20 ng/mL (50 nmol/L). However, levels exceeding 30 ng/mL may be more beneficial in preventing some health concerns.

If you suspect you’re deficient in vitamin D or might be soon, talk to your healthcare professional. They can test your levels. Depending on the results, they may recommend modifying your diet, spending more time in the sun, or taking supplements.

Adults should not take more than 4,000 IU (100 mcg) of vitamin D a day. You should not go over this limit without a doctor’s advice.

Taking too much vitamin D seldom happens. If you take too many supplements or get too much sun, it can happen. Always keep to the suggested dose on supplement bottles. Also, consult to a doctor before using any new supplements.

What are the primary sources of vitamin D?

Factors Affecting Vitamin D Absorption

Many things affect our body’s ability to manufacture or absorb vitamin D. These include skin color, age, body weight, and several health issues. Dark skin has more melanin, making it difficult for the skin to generate vitamin D from sunshine. Also, as we become older, our skin is less able to manufacture vitamin D.

Obesity Certain medical diseases, such as celiac disease, Crohn’s disease, and cystic fibrosis, might limit intestinal vitamin D absorption. Sunscreen use, clothes, and geographical location can all have an impact on vitamin D synthesis from sunlight.

Vitamin D and Overall Health

Vitamin D improves overall health beyond bone maintenance. It may protect against infections, serious diseases like cancer, cardiovascular and respiratory diseases, diabetes, and dementia. It also plays a role in mood management and minimizing the risk of depression.
