I blamed my demanding job. I put it down to getting older. I told myself stress was the reason. Every afternoon, I would hit a wall where even answering one more email felt impossible. By the time I got home, all I wanted to do was sit on the couch and stare at the television. I kept telling myself I just needed to be more disciplined. Go to bed earlier. Drink more water. Stop complaining. Push a little harder.

That became the story I told myself.

I wasn't sick. I wasn't looking for excuses. I simply believed everyone else was handling life better than I was, and I needed to catch up.

Then my doctor suggested checking my vitamin D levels.

I remember thinking it was an odd place to start. Vitamin D was something I associated with bone health, not with the exhaustion that seemed to follow me throughout my day. I certainly didn't expect that one conversation would make me question years of assumptions about my own body.

The more I learned, the more familiar the story became. I kept hearing the same thing from Black and Brown women who had spent years blaming themselves for feeling constantly drained before anyone explained there might be another reason they felt this way. It is the kind of fatigue that sleep can't fix, the kind that lingers even after a full night's rest.

That is why conversations about vitamin D matter. They are not about finding one simple answer. They are about helping more Black and Brown adults stop assuming that constant fatigue is simply something they have to live with.

Why Are Black and Brown Adults More Likely to Have Low Vitamin D?

Vitamin D is often called the sunshine vitamin because our bodies produce it when sunlight reaches our skin.

Most people stop learning about it there.

The part that receives far less attention is the role melanin plays in the process.

Melanin is the pigment that gives skin its color. It helps protect the skin from ultraviolet radiation, which is one reason darker skin developed the way it did. That protection is valuable. It is not something that needs fixing.

But it does change how vitamin D is produced.

What the research shows: Higher melanin levels can reduce the skin's ability to produce vitamin D from the same amount of sunlight. Two people can spend the same amount of time outdoors, yet their bodies may produce vitamin D at different rates. This does not mean deficiency is inevitable. It means there are biological and lifestyle factors worth understanding.

That difference matters. Especially when many of us are already spending most of our days indoors.

Why Doesn't More Sunlight Automatically Solve the Problem?

A woman once told me she laughed when her doctor mentioned vitamin D deficiency.

She lived in Arizona.

"If I get any more sun, I'll melt," she said.

At first glance, her reaction made sense. The state is known for sunshine.

The problem was that sunshine and sun exposure are not always the same thing.

She left home before work. Worked all day indoors. Drove home in the evening. Spent weekends catching up on errands, laundry, and everything else life had pushed aside during the week. The weather outside was beautiful. She barely experienced it.

Many of us live like this now. Our grandparents often spent more time outdoors than we do. Modern life has moved us inside. Offices, schools, hospitals, shopping centers, and even entertainment spaces are designed around indoor living.

That shift affects more than our relationship with nature. It affects our relationship with sunlight, too.

What Does Vitamin D Deficiency Feel Like?

This is where things become frustrating.

Vitamin D deficiency does not always arrive with a giant warning sign. Sometimes the symptoms are obvious, but more often they slip quietly into everyday life until they begin to feel normal. Fatigue is one of the most common complaints, not the kind that disappears after a relaxing weekend, but the kind that follows you from your morning commute to the grocery store after work and is still there when you finally sit down on the couch that evening.

Some people describe feeling physically drained despite getting enough sleep. Others notice muscle weakness, low motivation, or a general sense of not feeling like themselves.

The challenge is that there is almost always another explanation waiting nearby. You tell yourself work has been unusually busy, you've been staying up too late helping the kids with homework, or you're simply getting older. Before long, what started as a symptom became part of the story you told yourself about who you are.

That is why so many people spend years blaming themselves instead of asking whether something else could be contributing to how they feel. The conversation often ends before it even begins.

Why Have So Many of Us Learned to Ignore Feeling Run Down?

A Latina woman I used to work with admitted something to me that I have never forgotten.

She said she had stopped mentioning how tired she felt because she assumed everyone else was coping better. She had built a successful career, was raising a family, and was the person everyone called when they needed help. Feeling exhausted became part of the deal. She thought that was what adulthood looked like.

I think a lot of us do this.

We get so used to carrying responsibilities that we stop paying attention to what our bodies are trying to tell us. We tell ourselves we'll rest after this project, after the holidays, or once life finally slows down. Before we know it, feeling depleted has become our normal, and we stop asking whether it has to be.

Being resilient is something to be proud of. Believing you have to push through every symptom is something else entirely.

Why Is Vitamin D About More Than Bone Health?

Ask most people what vitamin D does, and they will mention bones. They are not wrong. Vitamin D plays an important role in helping the body absorb calcium and maintain bone health.

The conversation does not stop there.

Researchers continue to study vitamin D because it is involved in many functions throughout the body, including immune, muscle, and normal cellular functions. It also plays a role in supporting healthy muscle strength, which is one reason low vitamin D levels are sometimes linked with muscle weakness or aches. That is one reason healthcare providers often include vitamin D testing when evaluating ongoing concerns, especially when fatigue keeps showing up without a clear explanation.

This is where people sometimes become frustrated. They hear about vitamin D and expect a quick fix.

Health rarely works that way. No single nutrient explains every symptom. No supplement solves every problem. But understanding the role vitamin D plays can help us ask better questions about how we feel and why.

Why Are Black and Brown Communities Having More Conversations About Vitamin D?

For a long time, vitamin D was not something many people talked about unless it came up during a doctor's appointment. Feeling tired was easier to explain away. I think that is beginning to change. More people are asking why they feel exhausted all the time instead of assuming they simply have to live with it. They are paying closer attention to patterns, asking better questions, and realizing that constantly feeling run down should not automatically become part of everyday life.

That shift matters because understanding what your body is trying to tell you is always better than assuming you just have to push through it.

What Actually Helps?

Curiosity is a better place to begin than criticism.

If fatigue has become part of your everyday life, give yourself permission to pay attention to it instead of brushing it aside. If something feels different, or if you've spent years convincing yourself that everyone must feel this exhausted, it may be worth asking whether that assumption is true.

Vitamin D may or may not be part of your story. Either way, asking questions is often the first step toward understanding what your body has been trying to tell you.

Why I included vitamin D in the formula: I built Brown Body Reset because I was tired of being handed advice that assumed my body worked the same way as someone else's. I included D3 from lichen rather than lanolin, which means it works for anyone following a vegan or halal diet. Black and Brown adults are more likely to have low vitamin D levels, yet many of us spend years assuming constant fatigue is simply part of life. I also included vitamin K because it works alongside vitamin D to help the body use calcium effectively and support bone health. They belong together.

Looking back, I wish I had stopped questioning myself sooner. For years, I thought I just needed to work harder, sleep more, or become more disciplined. Learning that there could be another explanation changed the way I looked at my body. I stopped assuming I was the problem.

Questions About Vitamin D Deficiency

Why are Black and Brown adults more likely to have vitamin D deficiency?

Higher melanin levels can reduce the skin's ability to produce vitamin D from sunlight. This does not mean deficiency is guaranteed, but it can increase the likelihood of lower vitamin D levels, especially when combined with indoor lifestyles and limited sun exposure.

Can I have low vitamin D even if I live somewhere sunny?

Yes. Many people spend most of their day indoors, regardless of where they live. The amount of sunshine in your city is not always the same as the amount of sunlight your skin actually receives.

Does feeling tired automatically mean I have low vitamin D?

No. Fatigue can have many possible causes, including stress, sleep quality, nutrition, workload, and other health concerns. Vitamin D deficiency is only one possible explanation.

Why didn't the usual advice help me feel better?

Many people respond to fatigue by drinking more coffee, sleeping longer, or trying to push harder. If an underlying deficiency is contributing to the problem, those approaches may not address the root cause.

What foods naturally contain vitamin D?

Fatty fish, egg yolks, fortified milk, fortified breakfast cereals, fortified orange juice, and certain mushrooms are among the most common dietary sources of vitamin D.

Should everyone take a vitamin D supplement?

Not necessarily. Individual needs vary based on diet, lifestyle, age, health status, and sun exposure. A healthcare professional can help determine what makes sense for your situation.
