“I live in Florida. How could I be low on vitamin D?” We hear it often. It makes sense. We get sunshine almost every day.
But vitamin D in Florida isn’t as simple as living near the beach. Many people here spend most of the day indoors, wear sunscreen (good!), and cover up from the heat. Some take medicines or have health conditions that affect how they absorb nutrients. So yes, you can be low, even in the Sunshine State.
This guide explains who is at risk, why a lab test comes first, and the simple options once you know your number.

How Your Body Gets Vitamin D
According to the NIH Office of Dietary Supplements, your body gets vitamin D three ways:
- Sunlight on your skin. Your skin makes vitamin D when it’s exposed to UV light.
- Food. Fatty fish like salmon and tuna, egg yolks, and fortified milk, juice, and cereal.
- Supplements. Pills, chewables, or drops.
Vitamin D helps your body absorb calcium, which matters for bones. It also plays roles in muscles, nerves, and the immune system.
Who Is at Risk for Low Vitamin D in Florida?
The NIH lists several groups more likely to be low. Many of them live right here in Palm Beach County:
- Older adults. Skin makes less vitamin D with age.
- People with darker skin. More melanin means skin makes less vitamin D from the same sun.
- People who stay indoors most of the day, like office and night shift workers.
- People who always cover up or use high-SPF sunscreen. (Keep the sunscreen! Skin cancer is a real risk.)
- People with conditions that affect fat absorption, like Crohn’s disease or celiac disease.
- People with obesity or after weight loss surgery.
What about GLP-1 medicines?
People on semaglutide or tirzepatide often eat much less. A 2026 review in Clinical Obesity looked at nutrient gaps in people on GLP-1 medicines and listed vitamin D among the ones to watch, along with iron and B12. Less food can mean fewer nutrients. Our post on GLP-1 vitamin labs covers this in more detail.
Signs of Low Vitamin D
Here’s the tricky part: many people with low vitamin D feel nothing at all. When signs do show up, they can be vague:
- Tiredness
- Bone or muscle aches
- Muscle weakness
These signs of low vitamin D have many possible causes. That’s why guessing doesn’t work. A blood test does.
Why a Lab Test Comes First
Vitamin D is a fat-soluble vitamin. That means your body stores it, and too much can build up. The NIH notes that very high levels can cause nausea, vomiting, muscle weakness, confusion, kidney stones, and other problems. Most of the time, that comes from taking too many supplements.
So more is not always better. The safest plan:
- Get a blood test (25-hydroxy vitamin D) through your doctor or our clinic.
- Review your result with a clinician.
- Choose a plan that fits your number, your health, and any medicines you take.
Bring your medicine list
Some medicines interact with vitamin D, including certain steroids, weight loss drugs, and cholesterol medicines. Tell your clinician everything you take, including supplements.
Your Options After the Results
If your level is normal, you may not need anything extra. If it’s low, your clinician may suggest:
- Diet changes: more fatty fish, eggs, fortified foods.
- Safe sun habits: your doctor can advise what’s reasonable for your skin.
- An oral supplement at a dose your clinician picks.
- A vitamin D add-on at your visit, if your clinician thinks it fits.
At Majestic Aesthetics, vitamin D is available as an add-on on our IV drip menu. Some people pair it with the Immunity Drip. It’s not a cure for a deficiency or a replacement for your doctor’s plan. A clinician decides if it fits after reviewing your health.
Common Myths About Low Vitamin D
“A few minutes of sun fixes it.” Not always. Time of day, skin tone, sunscreen, clothing, and age all change how much vitamin D your skin makes.
“If I feel fine, I’m fine.” Many people with low vitamin D have no symptoms. Only a lab test tells you.
“More is better.” No. High doses can cause harm. Low vitamin D should be corrected with a dose your clinician chooses, then rechecked.
“A drip replaces my supplement.” Not necessarily. Your clinician decides the best form and dose for your results.
Vitamin D in Florida: Winter Tips
Winter here is mild, but days are shorter and many of us still stay inside. A few simple habits:
- Take a short walk outside during daylight.
- Eat vitamin D foods a few times a week.
- Recheck labs if your clinician asks you to.
- Don’t double up on supplements without asking. Many multivitamins already contain vitamin D.
Frequently Asked Questions
Can you really be low in vitamin D in Florida?
Yes. Indoor jobs, sunscreen, darker skin, age, health conditions, and some medicines can all lower vitamin D, even in Florida.
How do I know if I’m low?
A blood test called 25-hydroxy vitamin D is the way to know. Symptoms are often vague or absent.
Can I take too much vitamin D?
Yes. Vitamin D builds up in the body, and very high levels can be harmful. Follow your clinician’s dose.
Is a vitamin D add-on right for me?
Maybe. Your clinician will review your labs and health before suggesting one.
Does vitamin D help with GLP-1 side effects?
We can’t promise that. But people on GLP-1 medicines may want to check vitamin D along with other nutrients.
