Ever notice how winter makes you feel a bit like a houseplant desperately leaning toward a window for just an ounce of sunshine? There’s a reason for that! As the days get shorter and we bundle up in our favorite sweaters, knit hats and wool socks, our bodies miss out on vitamin D, also known as the “sunshine vitamin.” 

Why should you care? Well, vitamin D isn’t just about strong bones (though that’s definitely important!). It’s your body’s MVP for immune support and mood regulation (more on that later). Think of it as your internal cheerleader, helping keep your energy up and your winter blues at bay. 

Why vitamin D levels drop in winter 

Here’s the thing: Your body is like a tiny vitamin D factory, but it needs sunlight to operate. During winter, the sun plays hard to get, especially in the northern latitudes; it’s lower in the sky, less intense and we’re all bundled up like human burritos. The result? Your vitamin D production takes a serious nosedive, leading to fatigue, weakened immunity and even seasonal affective disorder (SAD). 

Why you need vitamin D 

Vitamin D plays a vital role in: 

• Bone health: It helps your body absorb calcium and phosphorus, which strengthens bones and prevents conditions like osteoporosis. 

• Immune function: It supports a healthy immune system and protects against colds and flu, which become more common in colder months. 

• Mood regulation: Vitamin D is linked to serotonin production, which influences mood and helps combat the “winter blues.” 

But there’s something you can do about it… 

Your delicious defense strategy 

Don’t worry; Mother Nature has your back! Here are some tasty ways to boost your vitamin D levels: 

1. Fatty fish: Wild-caught salmon, mackerel and sardines are vitamin D superstars. Just one serving of salmon delivers more vitamin D than a day at the beach. (OK, maybe not quite, but you get the idea.) These fish are also high in omega-3 fatty acids, which support heart and brain health. 

2. Egg yolks: The sun might not be up when you eat breakfast, but your morning eggs are secretly working overtime. Those golden yolks are packed with vitamin D goodness. Did someone say sunny side up? 

3. Mighty mushrooms: These fungi (e.g., portobello, maitake, shiitake) are fascinating. They make vitamin D just like we do when exposed to UV light. Look for UV-treated varieties for an extra boost. 

4. Fortified foods: Many everyday heroes, such as milk, orange juice and cereals, are fortified with vitamin D. It’s like getting a little extra sunshine in your breakfast bowl. 

5. Cheese, please: While not the richest source, cheese contributes to your daily intake. Plus, who needs an excuse to eat more cheese? 

6. Cod liver oil: OK, it might not win any taste contests, but it’s a vitamin D powerhouse. Think of it as liquid sunshine (if you can handle it!). 

Quick tips for your winter vitamin strategy 

• Make breakfast count: Start your day with fortified cereal or eggs (sunny side up, anyone?). 

• Get fish-friendly: Add fatty fish to your dinner rotation about 2-3 times a week. Not a fan of fish? Start with mild-flavored fish like cod or halibut. 

• Snack with purpose: Up your snacking game with string cheese, fortified yogurt with berries, or whole-grain crackers with tuna salad. 

• Soup it up: Make mushroom soup your new winter bestie. And add a splash of fortified milk or cream to make it even more vitamin D-friendly. 

The bottom line 

While nothing beats natural sunshine, you don’t have to hibernate until spring. With these food choices in your arsenal, you can keep your vitamin D levels happy even when the sun is being shy. 

Remember to have a chat with your healthcare provider about your vitamin D levels (especially before you think about adding supplements to your diet). They can help you determine what’s best for you during the darker months. 

Incorporate these delicious foods into your diet to help boost your vitamin D all season long!
