“Wait, you’re giving your baby Vitamin D drops daily?” Neha was surprised as she watched Riya, her neighbour, add Vitamin D drops to her baby’s routine.

“Yeah! Our paediatrician explained that breast milk doesn’t provide sufficient vitamin D, and it’s vital for strong bones and supports immunity.” Riya explained.

‘Isn’t sunlight supposed to be enough Vitamin D for newborns?”

Like Neha, many first-time parents don't realise that sunlight alone isn't enough for their newborns to get the needed Vitamin D. Their children silently suffer from Vitamin D deficiency, which goes unnoticed until symptoms become serious. Therefore, supplementing with infant vitamin D drops is essential for the baby’s healthy growth and development. Its impact goes beyond what many assume.

In this blog, we’ll explore why vitamin D is vital for infants, analyse the current state of vitamin D deficiency among children, identify the common signs of deficiency and how to ensure your baby receives the correct dose of Vitamin D easily and safely.

Role of Vitamin D and the Crisis We’re Ignoring

Vitamin D is vital for infants as it supports the absorption of phosphorus and calcium, essential nutrients for developing strong teeth and bones.

Nowadays, this deficiency disease is a significant health issue, especially among children, even though India receives plenty of sunlight. 46% of 100 children (0-10 years) in the Hyderabad study (2018-2019) demonstrating rickets symptoms were officially diagnosed.

So, the possible reasons for Vitamin D deficiency in Children are:

Insufficient Sunlight Exposure

Infants are specifically at risk of Vitamin D deficiency because they get limited sunlight due to a combination of factors, either from staying indoors, wearing protective clothing or applying sunscreen. Since breast milk contains only small amounts of vitamin D and many mothers may also be deficient, babies often don't get enough of this essential vitamin naturally.

Relying Solely on Breastmilk

Breast milk alone usually doesn't provide enough Vitamin D for babies, especially with limited sun exposure. Therefore, it’s generally recommended to give exclusive breastfeeding and a Vitamin D supplement of around 400 IU starting just a few days after birth to help ensure the baby builds strong bones and a healthy immune system.

Maternal Deficiency

Many pregnant women don’t get sufficient vitamin D, which can lead to some serious health issues, such as high blood pressure during pregnancy, gestational diabetes, preterm birth, and low birth weight. Supplements during pregnancy may help lower some risks associated with Vitamin D deficiency and boost the mother’s Vitamin D level.

Geographic and Seasonal factors

A child’s vitamin D levels can be immensely impacted by where they live and the time of year. Kids in colder regions or areas farther from the equator often get less sun exposure, especially in winter, which limits their ability to make sufficient Vitamin D.

Pollution vs Sunshine

Air pollution is another contributing factor that blocks sunlight, specifically UVB rays, which are vital for Vitamin D synthesis in the skin. Children growing up in such highly polluted areas are at a greater risk of not getting sufficient Vitamin D due to restricted sunlight exposure.

Because of these Vitamin D-deficiency-causing factors, giving infants Vitamin D supplements is essential to support their long-term health and well-being.

The Surprising Strength of Vitamin D Supplements

Vitamin D deficiency is common in infants and children due to limited sunlight exposure and other critical factors. Simple, affordable Vitamin D drops can help prevent serious health issues and support overall well-being.

Supports a Healthy Mood

Vitamin D supplements help regulate serotonin, a “feel-good” brain chemical. Adequate levels support better sleep patterns, emotional stability, and calm behaviour. While babies can’t express emotions like adults, vitamin D can help reduce fussiness and irritability and support holistic brain development while promoting healthy emotional growth in the long run.

Boosts Brain Development

In infants, Vitamin D supports the formation of neurons, which help regulate neurotransmitters like serotonin, further influencing mood and behaviour. These neurotransmitters protect brain tissues from inflammation and oxidative stress. By giving Vitamin D supplements, especially in the first few critical months, you contribute immensely to their brain development, helping them stay emotionally balanced and grow with a healthy mind.

Promotes Healthy Sleep

Vitamin D regulates melatonin, the hormone that controls sleep. It also affects brain chemicals like Serotonin, which define sleep patterns. It also plays a key role in maintaining the body’s internal clock, i.e., circadian rhythm, which supports quality sleep and timing in children.

Reduces the Risk of Allergies

Vitamin D helps shape a healthy immune system while minimising the risk of overreactions that may cause allergies. It actively strengthens the gut’s protective barrier in babies while shielding the system from allergens that can trigger allergic symptoms.

May Reduce Respiratory Infections

Vitamin D can minimise the risk and severity of respiratory infections by enhancing the immune response. It boosts protective peptides that combat infections, calm inflammation, and improve lung health while keeping children healthier and more resilient than ever.

Strengthens Heart Health

Vitamin D may reduce children's risk of heart disease by reducing inflammation and supporting blood vessel function. It can also help regulate calcium levels, crucial for proper heart muscle activity and circulation.

Supports a Healthy Weight

Vitamin D regulates fat storage and metabolism in young children. While low Vitamin D doesn't directly lead to weight gain, insufficient Vitamin D is directly connected to higher fat levels and reduced insulin resistance.

Reduces the Risk of Autoimmune Disorders

Vitamin D helps regulate the immune system and may minimise the severity of autoimmune diseases. Although low Vitamin D levels are common in affected children, Vitamin D supplements help control symptoms of autoimmune disorders like fatigue, mood changes, etc. and reduce reliance on heavy medications that tone down the immune system.

Signs your Baby May be Vitamin D Deficient

Though needed in small amounts, vitamin D supplements significantly affect your baby’s health. Unfortunately, many infants don’t get enough of it. Because the symptoms can be subtle, parents must keep a close eye and stay well-informed.

How to Ensure Your Baby Gets Enough Vitamin D?

Here is an elaborate table of six common baby feeding scenarios and their respective needs for Vitamin D supplementation. This list is based on pediatric guidelines and expert recommendations.

Don’t Let Hidden Deficiencies Turn into a Major Medical Bill

What starts as an invisible Vitamin D deficiency can lead to loud health problems tomorrow. The real risk lies in the fact that children suffer silently, unable to explain. That’s why having the right health insurance ensures timely check-ups, early diagnosis and access to the best treatment your child needs, even when your little one can’t speak up for themselves. Family health insurance covers you for high-quality treatment expenses and exceptional support to give your child a healthy start and a safety net when an infant's vitamin D drops and coverage go hand in hand.
