Look, everyone wants that "healthy glow," especially when January hits and the sky looks like a wet sidewalk. You’ve probably heard someone at the gym or in a Facebook group claim they hit the bulbs just to keep their levels up. It sounds logical. The sun gives you Vitamin D, tanning beds mimic the sun, so tanning beds give you Vitamin D. Right? Well, sort of, but mostly no. It’s a messy topic. Honestly, the answer to do you get vitamin d from tanning bed sessions depends entirely on what kind of light is hitting your skin, and usually, it’s not the kind you actually need.
Most people don’t realize that "UV light" isn't just one thing. It's a spectrum. When you stand outside, the sun hits you with a mix of UVA and UVB rays. Your body is a chemistry lab. When UVB rays hit your skin, they interact with a protein called 7-dehydrocholesterol. That’s the "aha!" moment where Vitamin D3 is born. But here is the kicker: tanning beds are designed to turn you brown, not to keep your bones strong.
The Science of Why Tanning Beds Usually Fail the D Test
To get a deep tan quickly without burning, salons use bulbs that are incredibly heavy on UVA rays. We are talking 95% UVA or higher in many cases. UVA is great at oxidizing melanin—the stuff that makes you look bronzed—but it does absolutely zero for your Vitamin D levels. It just doesn't have the energy to trigger the synthesis.
Actually, it's worse than that.
Some studies suggest that intense UVA exposure might even break down existing Vitamin D in your bloodstream. You could literally be tanning your way into a deficiency. Dr. Edward Giovannucci, a researcher at Harvard, has spent years looking at how Vitamin D impacts cancer risk, and the consensus among dermatologists at the American Academy of Dermatology (AAD) is pretty firm: tanning beds are a high-risk, low-reward way to try and fix a nutrient problem.
Think about the equipment. Most commercial beds use high-pressure lamps. These lamps are optimized for "immediate pigment darkening." They want you to walk out looking like you just flew back from Cabo. Because UVB causes sunburns (erythema) much faster than UVA, manufacturers dial the UVB way down. If a bed has 3% UVB and 97% UVA, you’re getting a massive dose of DNA-damaging radiation with only a tiny, incidental whisper of the stuff that helps your body make D. It’s like trying to get your daily serving of fruit by eating the cherry off a sundae.
The Vitamin D Dilemma: Supplementing vs. Frying
You might find some "specialty" beds out there. There are medical-grade phototherapy units, often used for psoriasis or vitiligo, that use narrowband UVB. Those will skyrocket your Vitamin D. But you won't find those at "Neon Palms Tanning Salon" next to the grocery store. Those are clinical tools.
If you are asking do you get vitamin d from tanning bed use because you’re feeling sluggish in the winter, you’re barking up the wrong tree. It’s just inefficient.
Let's talk numbers for a second. To get a decent dose of Vitamin D from the sun, a fair-skinned person might only need 10 to 15 minutes of exposure on their arms and legs a few times a week. Tanning beds deliver a concentrated blast of radiation that is often 10 to 15 times stronger than the midday sun. You're nuking your skin cells' DNA to get a nutrient you could get from a capsule that costs ten cents.
- UVA Rays: Penetrate deep. Cause wrinkles. Cause leather-like skin. Don't make Vitamin D.
- UVB Rays: Stay superficial. Cause burns. Make Vitamin D. Mostly filtered out of tanning beds.
The risk-to-benefit ratio is just broken. The World Health Organization (WHO) has classified tanning beds as Group 1 carcinogens. That’s the same category as asbestos and cigarettes. Is a bit of D worth the risk of melanoma? Probably not, especially when the D you're getting from a bed is so negligible.
Real Experts and the Tanning Industry Pushback
Now, if you talk to the Indoor Tanning Association, they’ll tell you a different story. They often point to the "Vitamin D winter"—the months in northern latitudes where the sun is too low in the sky for UVB rays to penetrate the atmosphere. They argue that tanning beds are a necessary surrogate.
But medical experts like Dr. Michael Holick, who is actually a proponent of sensible sun exposure, still emphasize that tanning beds are not the answer for the general public. The intensity is too high. The "dose" is uncontrolled. When you’re outside, your body has a built-in "off switch." Once you’ve made enough Vitamin D, the sun starts breaking down the excess so you don't get toxic levels. In a tanning bed, you're just getting a continuous, unnatural blast of UVA that provides no such regulation.

What Happens to Your Skin?
Let’s be real for a minute. Tanning is damage. There’s no such thing as a "base tan" that protects you. When your skin turns dark, it’s a distress signal. It’s your cells trying to shield their nuclei from further radiation.
If you’re using a tanning bed, you’re accelerating photoaging. You’ll see it in your 40s. The "smoker’s skin" look, the fine lines, the sunspots. All of that happens because UVA destroys collagen fibers. So, even if you managed to find a bed with enough UVB to boost your D levels, you’re trading your skin’s structural integrity for a nutrient you can get from salmon or a pill.
Better Ways to Get Your Levels Up
If you're worried about your levels, the first step isn't a tanning membership. It’s a blood test. Ask for a 25-hydroxyvitamin D test.
Most people are deficient. That’s a fact. But the solution is boringly simple.
- Dietary Sources: Fatty fish like salmon, mackerel, and sardines are gold mines. Egg yolks have some, too.
- Fortified Foods: Milk, orange juice, and cereals are often pumped with D2 or D3.
- Supplements: Vitamin D3 (cholecalciferol) is the preferred form. It’s more effective at raising blood levels than D2.
- Short Bursts of Natural Sun: If it’s summer, 10 minutes is usually plenty.
I’ve seen people argue that "natural" Vitamin D from light is better than "synthetic" pills. Biologically, your body handles D3 from a supplement almost identically to the D3 it makes in your skin. There is no magical "energy" from the tanning bed that makes the Vitamin D superior.
The Final Verdict on Tanning Beds and Vitamin D
So, do you get vitamin d from tanning bed sessions? Technically, you might get a tiny, insignificant amount if the bulbs have a UVB component. But practically? No. You are getting a massive dose of aging UVA rays and a significantly increased risk of skin cancer for almost no nutritional gain.
If you want to be healthy, stop looking at the tanning salon as a wellness center. It’s a cosmetic business. There’s nothing wrong with wanting a tan, but let’s not pretend it’s a medical necessity. Use a self-tanning lotion if you want the color. Take a supplement if you want the D.
Practical Steps for Success
- Get Tested: Don't guess. See where your levels actually sit before you start mega-dosing anything.
- Check Your Bulbs: If you absolutely insist on using a bed, ask the salon for the spectral output of their lamps. If they don't know what you're talking about, that's your sign.
- Focus on D3: If you supplement, make sure it's D3, not D2.
- Eat Your D: Incorporate more fatty fish into your weekly meal prep. It’s good for your heart anyway.
- Use Sunscreen: Even if you're trying to get Vitamin D outside, you only need a few minutes of "naked" skin. After that, slather on the SPF 30 to prevent the damage that tanning beds specialize in.
Stop overcomplicating it. The tanning bed is for aesthetics, and even then, it’s a risky one. For your health, look to the kitchen and the pharmacy, not the UV tubes.
