Sunshine in the sky. Vitamin D

Vitamin D is one of the most underrated yet essential nutrients for overall health and wellbeing. Often called the “sunshine vitamin,” it plays a crucial role in multiple bodily functions, from bone health to immune support. Despite its importance, vitamin D deficiency is widespread, affecting millions worldwide. In this post, we’ll dive into why vitamin D is vital, what happens when we don’t get enough, and how to safely increase our levels.


Why Is Vitamin D So Important?

Vitamin D is essential for:

  • Bone Health: It helps the body absorb calcium and phosphorus, which are critical for maintaining strong bones and preventing osteoporosis.

  • Immune Function: Adequate vitamin D levels help strengthen the immune system, making it easier to fight off infections.

  • Muscle Strength and Function: Deficiency has been linked to muscle weakness, which can increase the risk of falls, especially in older adults.

  • Mood and Mental Health: Low levels have been associated with increased risk of depression and anxiety.

  • Inflammation Control: Vitamin D plays a role in reducing chronic inflammation, which is linked to numerous diseases, including heart disease and autoimmune conditions.


What Happens When We’re Deficient?

Vitamin D deficiency can lead to various health problems, including:

  • Weakened Bones: In children, it can cause rickets (soft, weak bones), while in adults, it can contribute to osteoporosis and fractures.

  • Frequent Illnesses: A weakened immune system means more colds, flu, and other infections.

  • Fatigue and Muscle Weakness: Chronic fatigue and unexplained muscle pain can be signs of low vitamin D levels.

  • Depression and Mood Disorders: Seasonal Affective Disorder (SAD) and other mood imbalances have been linked to low vitamin D levels.


There are several ways to boost vitamin D levels while keeping safety in mind:


1. Sunlight Exposure

The most natural way to get vitamin D is through sun exposure. Spending about 10-30 minutes in the sun can help the body produce enough vitamin D. Try to get outside first thing for morning sun to boost your levels, your mood, and set you up for the day and again in the late afternoon to settle your nervous system to prepare for a good night sleep.


2. Dietary Sources

While not many foods naturally contain vitamin D, here are some great options:

  • Fatty fish (salmon, mackerel, sardines)

  • Egg yolks

  • Beef liver

  • Raw dairy


3. Supplements

For those who don’t get enough sun or dietary vitamin D, supplementation is a reliable option, but should never be your first choice. The recommended daily intake varies, but most adults benefit from 600-800 IU per day, with higher doses sometimes needed based on individual health needs (always check with a healthcare provider).


Vitamin D is a game-changer when it comes to overall health. From strong bones to a resilient immune system and improved mood, it plays a crucial role in keeping us feeling our best. So get outside in the Texas sun, we are so fortunate to have the good stuff in abundance! And if you’re worried about your levels, consider getting a blood test to check. So many of us are deficient due to our digital lifestyle, so make the necessary lifestyle adjustments today. Your body—and mind—will thank you!
