Every fall, one of the things I start paying a little more attention to is my Vitamin D.
I’m definitely a solar powered person. I feel better when I’m outside, the sun is shining, and there are more hours of daylight.
So when the days get shorter and we start spending more time indoors here in Canada, Vitamin D becomes something I think about a little more.
Vitamin D plays an important role in bone and muscle health, calcium absorption, immune function and overall health. It also has a connection with mood, which is something I think is especially worth paying attention to as we move into the darker, wetter months.
And while our bodies can make Vitamin D from sunlight, getting enough can be more difficult during Canadian winters.
Some people are also more likely to have lower levels, including those who spend most of their time indoors, have darker skin, consistently use sun protection, have certain digestive or absorption issues, or take medications that can affect Vitamin D status.
Some food sources of vitamin D include:
- Salmon
- Sardines
- Mackerel
- Egg yolks
- Liver
- Fortified milk and dairy alternatives
- Some mushrooms
And yes, supplementation can be helpful for some people, particularly through the fall and winter.
But this is one supplement I don’t think we should approach with a “more is better” mindset. Your Vitamin D needs are individual, and a blood test can help give you a much clearer picture of where you’re actually at.
For women in their 40s and beyond, I think it’s worth having Vitamin D on your radar alongside the other pieces of the bigger picture, especially bone health, muscle health, mood and hormone changes.
If you’re feeling more tired, foggy, low in mood or generally not quite like yourself as the seasons change, it’s worth looking at the whole picture rather than assuming one nutrient is the answer.
Your health is rarely about one supplement. It’s about putting the pieces together.
If you’re wondering whether Vitamin D is something you should be paying attention to, I’m always happy to help you look at the bigger picture.
