People tend to soak up more sun in summer, but that doesn’t always mean they’re getting enough vitamin D. Everyone is different, and we all have a number of factors in our lives that affect our ability to produce vitamin D, including things like where we live, what our skin tone is, and how old we are. Our skin doesn’t always reliably convert the sun’s rays into vitamin D, especially if we’re trying to be sun-safe and we cover up with clothing and sunscreen. So, it’s important to keep taking a high-quality vitamin D3 supplement, even in the summer!
