Image by RyanJLane / iStockApril 15, 2025It’s not just anecdotal—good health is harder to maintain as you age. And one of the most noticeable changes is that your fitness level seems to stagnate and you start to lose muscle (even with your same rigorous workouts). Muscle loss actually starts to occur in your 30s and you lose as much as 8% each decade—so by the time you cross 40, you can start to feel the effects. However, building muscle and strength at any age is possible with the right habits.

But one part of muscle health many of us overlook is vitamin D. Bone health is vitamin D’s claim to fame, but this vitamin impacts all types of lean mass—including muscle.* Not to mention immunity, gut health, mood, and cellular aging of course.

Image by evrim ertik / iStockApril 11, 2025When you hear the word creatine, a picture of a bulk man ripping through chest presses may come to mind (or at least that’s my mental image). But this supplement isn’t just for helping men with big muscles get even bigger muscles. Creatine is a compound that is especially important for women—and one that many are lacking. So, there’s the potential that creatine supplements may have even greater effects in women.
