Why You Really Need to Care About Vitamin D (Especially If You’re Over 40)

Let’s talk sunshine. Not just beach days and backyard barbies, we’re talking about Vitamin D, often called the “sunshine vitamin,” and it’s more important than you might think. Especially for Aussie women navigating perimenopause, menopause, or just trying to stay healthy and energised.

The Vitamin D Lowdown

Vitamin D is more than just a helper for bones, it also plays a crucial role in:

• Reducing inflammation - low levels are linked with inflammation, which can be a sneaky contributor to serious chronic conditions, including cancer.

• Helping with weight management - some studies show that getting enough Vitamin D may help reduce body fat and support weight loss.

• Immune defence, cellular development, and nervous system balance - acting as a vital regulator behind the scenes.

But here’s the catch, just getting enough sun or eating Vitamin D-rich foods isn’t quite enough. To actually activate Vitamin D so your body can use it, you need a healthy liver and kidneys. Yep, your organs are part of the equation, and they play a pretty important behind-the-scenes role.

Here’s how it works: When your skin absorbs sunlight, it produces a form of Vitamin D called cholecalciferol (Vitamin D3). But this is just the raw material, kind of like having flour but not yet a cake. Your liver then converts it into a storage form called calcidiol, and from there, your kidneys step in to convert it again into calcitriol. This is the active, usable form your body needs to do important jobs like regulating calcium, supporting immune function, balancing hormones, and protecting your bones.

So, if your liver or kidneys aren’t functioning well (due to illness, medications, or age-related changes), this conversion process might not happen efficiently, even if you're getting plenty of sun or supplements. That’s why it’s worth checking in with your GP if you suspect low Vitamin D levels, especially if you have underlying health conditions.

In short: it’s not just about getting enough, it’s also about processing it properly. Your body is clever, but it needs the right support to do its thing.

The Sun: Still the Best Source

Australia is in a sweet spot when it comes to soaking up sunshine, we produce up to 4 times more Vitamin D than people in places further from the equator. That’s a win!

Here’s how to do it safely:

• Aim for sun exposure before 10am or after 2pm

• Expose just 20% of your body (arms, legs, feet or hands is enough)

• In summer: 10 -15 mins

• In winter: 20 - 30 mins, depending on your location

If you have darker skin, you may need a little more time outside, as melanin naturally blocks UV absorption.

What About Food?

While sunlight is the best source, you can also sneak in some Vitamin D through your diet. Try these:

• Mushrooms (especially if they’ve been exposed to sunshine)

• Eggs, liver and oily fish like sardines or salmon

• Fortified foods - check labels on plant milks, cereals and breads

• Supplements - only if needed! Always check your levels with your GP before popping a pill.

A Holistic Reminder

Vitamin D is just one part of the health puzzle. A balanced, whole food diet with plenty of colourful plants, protein, fibre and healthy fats will support your body from all angles, not just for Vitamin D, but for mood, hormones, skin, and overall vitality.

Whether you’re 35 or 65, staying on top of your Vitamin D game is one of the simplest ways to protect your long-term health. So next time the sun peeks out, soak in it safely.
