Vitamin D: You’re Probably Not Getting Enough

Why You Need Vitamin D Year-Round 

Vitamin D is unique—it's the only vitamin your body can produce on its own. Unlike other vitamins that must come from food, your skin synthesizes vitamin D when exposed to sunlight. However, not everyone produces it efficiently. Genetic factors can impact how well your body converts sunlight into vitamin D, meaning some people may always be at risk of deficiency—even during summer.

Because vitamin D plays a vital role in bone health, immune function, and overall well-being, it's crucial to monitor your levels regularly. Getting a blood test should be part of your yearly health routine to ensure you're not unknowingly running low, which can impact everything from your energy levels to your recovery from exercise.

Vitamin D in Winter: Why You’re Probably Not Getting Enough

When the days get shorter and the sun hides behind clouds, our natural vitamin D production takes a nosedive. In New Zealand, especially in the southern regions, the sun’s UVB rays aren’t strong enough in winter to trigger sufficient vitamin D synthesis in the skin. This can lead to low levels, which may cause symptoms like fatigue, muscle weakness, low mood, and a weakened immune system.

Why Does This Matter?

• Immune Support: Vitamin D plays a key role in keeping your immune system strong, helping to fight off colds and flu.

• Bone Health: It helps your body absorb calcium, reducing the risk of bone weakness and fractures.

• Mood & Mental Well-being: Low vitamin D levels have been linked to seasonal affective disorder (SAD) and general feelings of sluggishness.

How to Get Enough in Winter:

• Supplementation: For many people, a vitamin D supplement is the easiest way to maintain optimal levels. BioTrace Vitamin D3 + K2 is a highly absorbable option that pairs vitamin D3 with K2 to ensure calcium is directed to bones rather than soft tissues.

• Pair with Magnesium: Magnesium is crucial for activating vitamin D and supporting over 300 biochemical reactions in the body. Without it, your body may struggle to efficiently use vitamin D.

• Dietary Sources: Fatty fish (salmon, mackerel), egg yolks, and fortified foods can provide some vitamin D.

• Outdoor Time: Even a little midday sun exposure can help, but it’s often not enough in winter months.

Vitamin D in Summer: Don’t Get Too Complacent

You’d think summer means we’re all getting plenty of vitamin D, right? Not necessarily. Many people still fall short due to lifestyle habits—like working indoors, covering up with sunscreen and clothing, or spending more time in the shade.

Why Does It Still Matter?

• Muscle Recovery & Performance: Whether you're hitting the gym, running trails, or just staying active, vitamin D supports muscle strength and function.

• Inflammation & Recovery: It helps regulate inflammation in the body, crucial for both athletes and anyone looking to recover well from workouts.

• Long-Term Health: Maintaining good levels year-round supports heart health, brain function, and hormone balance.

How to Optimize Your Vitamin D in Summer:

• Smart Sun Exposure: Aim for short bursts (10-20 minutes) of direct sunlight on bare skin before applying sunscreen.

• Pair with Key Nutrients: Vitamin D works best when taken with magnesium (for activation), vitamin K2 (for calcium regulation), and healthy fats (for absorption).

• Monitor Your Levels: If you’re unsure, a blood test can confirm if you’re getting enough.

Final Thoughts: A Year-Round Approach

Vitamin D isn’t just a winter issue—it’s something to be mindful of throughout the year. Whether you get it from the sun, food, or supplements, making sure your levels stay optimal will help keep your energy up, your immune system strong, and your overall health in check.

One of the best ways to ensure you’re getting the right balance of vitamin D and its supporting nutrients is through high-quality supplementation. BioTrace Vitamin D3 + K2 offers a powerful combination that enhances absorption and directs calcium where it’s needed most. Magnesium plays a crucial role in activating vitamin D and ensuring its effectiveness. By combining these key nutrients, you can maximize the benefits of vitamin D for bone health, muscle function, and overall well-being.

So, whether it’s winter or summer, don’t ignore your vitamin D! Your body will thank you for it.
