Together, these nutrients form a powerhouse duo that is imperative for maintaining healthy bones and overall skeletal health.

How Much Vitamin D Do You Need?

If you’ve ever wondered how much vitamin D your body requires, you’re not alone. Determining the right amount of this important nutrient can be confusing, but it’s crucial for overall health and well-being. Let’s break down the recommendations for different age groups and the factors that influence your vitamin D needs.

Recommended Daily Intake for Different Age Groups

Different age groups have varying needs when it comes to vitamin D intake. For infants up to 12 months, the recommended amount is 400 IU (International Units) per day. Children and adults up to age 70 should aim for 600 IU daily, while adults over 70 may need a bit more at 800 IU per day. These recommendations are based on maintaining adequate blood levels of vitamin D to support bone health, immune function, and overall wellness.
