As professional women, we juggle demanding careers, families, and personal wellness. We know how important it is to fuel our bodies properly, yet one essential nutrient often flies under the radar—vitamin D. Dubbed the “sunshine vitamin,” it plays a critical role in immune health, mental clarity, bone strength, and even gut health. But here’s the catch: many of us aren’t getting enough, and the reason may be written in our genes.

Why Vitamin D Matters More Than You Think

Vitamin D is not just about strong bones. It’s a powerful regulator of immune function, helping to defend against infections and inflammation. Studies also show its impact on mental well-being, with deficiencies linked to mood disorders, brain fog, and fatigue. Additionally, vitamin D supports gut health by regulating the gut microbiome, a key factor in digestion and overall wellness.

With all these benefits, you’d think getting enough vitamin D would be easy. But for many women, standard recommendations fall short—especially if you have genetic variants that affect how your body absorbs and utilizes it.

Your Genes Control How Much Vitamin D You Actually Absorb

If you’re spending time outside, eating salmon, and even supplementing vitamin D but still finding your levels low, you’re not alone. I know this firsthand.

I have multiple variants on my VDR gene (vitamin D receptor gene), which means no matter how much sunlight I get or how many vitamin D-rich foods I eat, my body struggles to maintain adequate levels. To compensate, I have to take nearly 10,000 IU of vitamin D daily—a stark contrast to the 400 IU that some people may need. And since too much vitamin D can be toxic and too little can be detrimental, it’s essential to know what your body actually requires.

This is where nutrigenomics comes in. By understanding your genetic makeup, you can determine the exact vitamin D intake that’s right for you—no more guesswork, no more unnecessary supplementation, just precision health.

Common Signs You Might Be Deficient (Even If You Think You’re Not)

Many women don’t realize they’re deficient until symptoms creep in. Here are some common warning signs:

Frequent colds or infections

Chronic fatigue or low energy

Brain fog or difficulty concentrating

Muscle weakness or joint pain

Mood swings, anxiety, or depressive symptoms

Digestive issues or gut discomfort

Sound familiar? If so, it may be time to take a closer look at your vitamin D levels—and your genes.

The Role of VDR SNPs in Vitamin D Absorption

Your ability to absorb and utilize vitamin D is heavily influenced by single nucleotide polymorphisms (SNPs) in the VDR gene. These genetic variations can impact how efficiently vitamin D binds to its receptors and is activated within the body. If you have these SNPs, your body may struggle to maintain optimal levels, even if you’re getting the “recommended” amount.

This is why a one-size-fits-all approach to vitamin D simply doesn’t work. Personalized nutrition, based on your unique genetic blueprint, is the future of health—and vitamin D is no exception.

How to Find Out If You Need More Vitamin D

You don’t have to rely on guesswork when it comes to your health. Here’s how to take control:

Get Your Levels Tested – A simple blood test can measure your vitamin D levels. However, knowing your levels alone isn’t enough.

Understand Your Genetic Predisposition – Genetic testing can identify if you have VDR SNPs that affect how your body absorbs and utilizes vitamin D.

Optimize Your Intake Based on Your DNA – With nutrigenomics, you can personalize your supplementation to meet your body’s precise needs.

The Future of Nutrition is Personalized

The National Institutes of Health (NIH) predicts that precision nutrition will be the gold standard in medicine by 2030. Instead of following generalized guidelines, more people are turning to science-backed, DNA-driven solutions to take the guesswork out of health.
