Vitamin D is essential for good health. It helps the body absorb calcium from food, which is vital for strong bones and teeth. It also supports the immune system, muscle function, and brain health. While some vitamin D is obtained from foods like fatty fish, margarine, and eggs, a significant portion is produced in the skin through sunlight exposure. However, in climates where sunlight is limited, or if you spend most of your time indoors or don’t consume enough vitamin D-rich foods, you might be at risk of developing a deficiency.
A vitamin D deficiency can cause a range of symptoms, such as:
- Muscle pain, cramps, or weakness
- Feelings of sadness or depression
- Fatigue or low energy
If left untreated, a lack of vitamin D can lead to more serious issues over time, like osteoporosis (weakened bones) in adults or abnormal bone development in children. It’s also associated with a higher risk of conditions like diabetes, heart disease, and certain cancers.
