Why You Are Probably Still Low on Vitamin D
Share
Key Takeaways:
- • The Sunless Zones: Anyone living above the 35th parallel line cannot make vitamin D from the sun for half the year, no matter how bright the sky looks.
- • The Glass Blocker: Commercial glass in office and car windows filters out 100% of the UVB rays your skin needs to synthesize vitamin D.
- • The DNA Blind Spot: Genetic variations cause many people to be non-responders who fail to absorb standard vitamin D supplements.
- • Oil-Based Delivery: Vitamin D is fat-soluble, meaning dry pill capsules are poorly absorbed compared to pure liquid drops in a healthy oil base.
Every health site says the same thing: just spend 15 minutes outside a few times a week.
But for most Americans, that advice does not work. You might still feel tired and sluggish. Or maybe you already take a pill or spend time outside, but your vitamin D levels just will not go up.
The standard rules ignore how sunlight actually works. A summer tan or a winter walk does not mean your skin is making what it needs. Where you live, office windows, and your own DNA can completely block the sun's benefits.
Even worse, standard dry pills are hard for your body to use. To actually absorb this vitamin, you need it in a liquid oil base.
Here is what is really stopping your body from getting enough vitamin D, and how to fix it.
Why Your Location Blanks Out the Sun
Most people think a bright, sunny day is all it takes to get vitamin D. Unfortunately, physics says otherwise.
To make vitamin D, your skin needs a specific type of light called UVB rays. The problem is that the Earth tilts away from the sun for several months out of the year. If you live anywhere in the top half of the United States, basically anywhere north of Atlanta or Los Angeles, the sun sits too low in the sky from October to April.
Because of that low angle, the atmosphere blocks every single UVB ray before it can reach your skin. You could stand outside all afternoon in November, but your body still will not produce any vitamin D.
There is a very easy way to check this tomorrow, called the shadow test:
- Look at your shadow when you are outside.
- If your shadow is longer than you are tall, the sun angle is too low.
- A long shadow means your skin cannot make a single drop of vitamin D.
This geographic trap is the main reason why millions of people see their vitamin D levels crash every winter, even if they spend time outdoors.
The Office Window Trap
Many of us think we are getting a head start on our vitamin D while driving to work or sitting by a sunny window in the office. It feels warm and bright, so it seems like it should be working.
But it isn't.
Commercial glass is specifically designed to block the sun's most powerful rays. It easily filters out 100% of the UVB light your body requires to build vitamin D.
At the same time, that glass allows UVA rays to pass right through. UVA rays are the ones responsible for skin aging and wrinkles. So when you sit by a window on a sunny afternoon, you are getting all of the skin-aging rays, but absolutely none of the health benefits.
Spending your day in a car, an office, or a sunny room still leaves your body in the dark. If you spend most of your daylight hours behind glass, your sun exposure is essentially zero.
The DNA Blind Spot: Why Some People Can’t Absorb the Sun
Have you ever taken a vitamin D pill every day, or spent tons of time outside, only to have your doctor tell you your blood levels are still low?
You might be a non-responder.
Everyone has vitamin D receptors in their cells. Think of these receptors like little baseball gloves that need to catch the vitamin D in your bloodstream. Because of natural variations in our DNA, some people are born with receptors that are shaped a bit differently. Their gloves have a very hard time catching the vitamin.
Studies show that up to 25% of people have this genetic trait. If you have it, standard doses of vitamin D will barely move the needle for you. You actually need a much more efficient delivery system to get the vitamin into your cells.
This is why a simple blood test is so important. If you are doing everything right but your numbers stay flat, your genetics are likely working against you.
Why Dry Pills Fail (And the Liquid Oil Solution)
If your location, your office windows, or your genetics are working against you, a standard dry vitamin D pill usually will not fix the problem.
Vitamin D is fat-soluble. This means your body cannot absorb it without fat. Most cheap supplements come in a dry capsule or hard tablet. If you swallow one of these on an empty stomach with a glass of water, it passes right through your system without doing much good.
To actually solve a deficiency, you need vitamin D in a liquid drop form with an oil base.
Liquid drops bypass the issues of dry pills. The oil base gives your body the exact fat it needs to absorb the vitamin right away. Plus, drops allow you to easily adjust your dose if your DNA makes it harder for you to absorb it.

A landmark study published in The Journal of Clinical Endocrinology and Metabolism proved that exposing skin to winter sunlight in northern locations (like Boston) will not produce any vitamin D3 in human skin due to the low solar zenith angle. [See Study]
A study published in Photochemistry and Photobiology measured ultraviolet rays in everyday environments. It found that while shade still scattered some light, the UVB rays needed for vitamin D inside a car with the windows closed dropped to exactly 0%. [See Study]
A systematic review and meta-analysis published in Nutrients reviewed how specific VDR gene variants (like TaqI and BsmI) directly modulate and restrict how a person’s blood levels respond to vitamin D supplements. [See Study]
Research published by the American Society for Bone and Mineral Research showed that taking vitamin D alongside a fat-containing meal or vehicle improves systemic absorption, resulting in an average 50% increase in serum levels. [See Study]
