Did you know that taking vitamin D without food can reduce its absorption?

Many people don’t realize it, but how you take vitamin D can directly affect how well it works. Essential for bone health, immune function, and overall well-being, this nutrient depends on one key factor that’s often overlooked: the presence of fat during intake.

Because vitamin D is fat-soluble, it needs dietary fat to be properly absorbed by the body. The recommendation is simple: take your supplement with a main meal — such as breakfast, lunch, or dinner — ideally including foods like eggs, olive oil, nuts, avocado, or full-fat yogurt.

And what about orange juice? If your supplement comes in oil-based capsules or drops, you can take it with juice — but absorption will be less effective than when taken with a full meal that includes healthy fats.

The ideal dose of vitamin D varies by age, blood test results, and medical advice. In general, healthy adults need between 600 and 2,000 IU per day.

Taking vitamin D the right way is a small habit — but one that can have a big impact on your health, immunity, and quality of life.
