Prolonged hair loss, frequent fatigue, or persistent digestive disorders are often seen as separate problems. However, according to nutrition experts, in many cases, these manifestations originate from a common but easily overlooked cause: vitamin D deficiency.
Vitamin D is not only a micronutrient that supports bones and joints, but also acts like a hormone, participating in regulating inflammation, metabolizing energy, the immune system, gut health and even the development cycle of hair. When vitamin D levels in the body are low, a series of physiological functions can be silently affected.
Ms. Deepsikha Jain, a nutritionist with a Master's degree in Global Community Health Nutrition in the UK and a national diabetes educator certified in India, said that regularly supplementing with vitamin D3 for about three months, if indicated correctly, can bring many comprehensive health benefits.
Nutrition expert Deepsikha Jain has pointed out 4 of the most common positive changes, including:
Reduces systemic inflammation
According to Deepsikha Jain, vitamin D3 has the effect of regulating inflammatory reactions in the body. When inflammatory levels decrease, many chronic health problems are also improved over time.
Vitamin D3 acts as a hormone that helps reduce inflammation, thereby having a positive impact on PCOS, thyroid disorders, diabetes, digestive problems and some autoimmune diseases," Ms. Deepsikha Jain explained.
Infection control is seen as the foundation for long-term health improvement.
Maintain stable energy
Another clear benefit of supplementing vitamin D3 is improving daily energy levels. Many people who lack vitamin D often feel sluggish and tired even when getting enough sleep.
According to Ms. Deepsikha Jain, after a reasonable period of supplementation, the body will feel more alert, reduce prolonged exhaustion and maintain better concentration during the day.
Improve gut health
Vitamin D3 also plays an important role in the digestive system. Deepsikha Jain said that this micronutrient helps strengthen the intestinal lining barrier, while supporting the diversity of intestinal microorganisms. When the intestinal tract is healthier, nutrient absorption is improved, and symptoms such as bloating, indigestion, or digestive disorders also tend to decrease.
Reduce hair loss
Hair loss is a common sign in people who are deficient in vitamin D but are not paid attention to. Nutritionists say that vitamin D3 participates in the hair follicle's development cycle, and deficiency can cause more hair loss.
When supplemented properly, hair loss can be significantly reduced," Ms. Deepsikha Jain said, while emphasizing the need to test vitamin D levels and consult a doctor before use.
Deepsikha Jain noted that vitamin D3 is not "a tonic to use as much as possible". Supplementation needs to be based on blood tests and medical instructions to avoid the risk of excess.
When used properly, vitamin D3 can become an important factor in improving overall health, far exceeding the familiar role for bones and joints.
