The Worst Time to Take a Vitamin D Supplement
Vitamins dont directly supply the energy that runs your body, but by serving as co-factors, they play a key support function for many aspects of health. The human body needs vitamins and minerals to function, but it cant produce enough on its own. Instead, you must get them through diet. Thats why its so important to make healthy, nutrient-dense food selections rather than dining on ultra-processed foods that contain empty calories.
One vitamin that most people dont get enough of is vitamin D, the sunshine vitamin. Its called the sunshine vitamin because the best natural source of vitamin D is exposing your skin to sunlight. When sunlight hits your skin, ultraviolet rays convert a compound on your skin to a precursor of vitamin D. Then, your liver and kidneys activate this pre-vitamin D compound and transform it into an active form your body can use.
Since food isnt a good source of vitamin D, except for fatty fish, egg yolks, and foods fortified with vitamin D, and not everyone gets enough sunlight, vitamin D deficiency is common. The National Health and Nutrition Examination Survey 2005 to 2006 found that 41% of Americans are deficient in vitamin D.
The Best Time To Take Vitamin D

Its convenient to remember to take your vitamins and dietary supplements in the morning, either with breakfast or a cup of Bulletproof Coffee. But you dont have to take it in the morning. If youre curious about supplementing while fasting, just take it when you break your fast.
You may also want to take vitamin D with your largest meal of the day, whenever that is for you, since research has found that this can improve absorption. More specifically, researchers suggest taking vitamin D at the same time you eat foods that are high in fat. Whenever you take vitamin D supplements, consider taking them while eating quality fat sources, including avocado, Bulletproof Brain Octane C8 MCT Oil, egg yolks, wild-caught fatty fish, grass-fed butter and Bulletproof Grass-Fed Ghee.

To stay consistent, though, Crouch suggests trying tying your vitamin D supplement to some other part of your routine that happens daily, like drinking your morning coffee or brushing your teeth. If it doesn’t contain fat, try tying it to your breakfast .* If lunch or dinner works better for your D ritual, go for it!
And if you happen to take your vitamin D at different times or even forget to take it here and there, don’t panic. “Vitamin D is very forgiving,” Holick says. “If you forget it one day, you can take double the next day.” No sweat!*

What Is Vitamin D
We need Vitamin D for bone, brain, lung and heart health, as well as reducing the risk of chronic conditions, improving our cellular growth and keeping our immune systems functioning well.
Its different from other vitamins in that we can actually produce it ourselves, mainly in our skin as a response to the UVB rays in sunlight, giving it the delightful name The Sunshine Vitamin. However, we can also bolster our intake during rainy days with the foods we eat, such as mushrooms and fortified plant-based products, or by taking a supplement. This helps to avoid a deficiency, which can lead to fatigue, depression, pain and weakness – so we need to make sure we keep those blood levels up!

Vitamin D And Sleep: The Surprising Connection
Vitamin D and sleep quality go hand-in-hand. Early research suggests vitamin D is inversely related to melatonin, your sleep hormone. Increasing vitamin D levels may suppress melatonin levels. So, it makes sense that taking it at night could disrupt your sleep.
That said, you still want to get enough vitamin D because your levels are directly related to the amount and quality of sleep youre getting. Researchers have found that low levels of vitamin D are linked with poor sleep quality. In one study, participants who increased their vitamin D levels saw significant improvement in sleep and neurologic symptoms.
In another study, researchers looked at the vitamin D levels and sleep quality of 3,048 men 68 years and older. They measured total sleep time, wake times and frequency and sleep efficiency, which measures the time spent in bed versus the time spent sleeping. The study found that low levels of vitamin D were linked with poor quality sleep and sleeping less than five hours a night. Low levels of vitamin D were also associated with lower sleep efficiency scores.
We know that vitamin D and sleep quality are linked, but were only really just beginning to understand how and why thats the case. Researchers believe that vitamin D may affect our shut-eye by interacting with the areas of the brain that regulate sleep. We also know that vitamin D plays a key role in supporting the immune system, and managing inflammation may support better sleep quality.

Are Vitamin D Supplements Important
This fat-soluble vitamin comes in two forms: D2 and D3. Its D3 that helps our bodies absorb and maintain calcium and phosphate. Both are linked to bone health. However, sunlight has long been the source of our vitamin D due to very few foods that are truly rich enough in vitamin D. The vitamin has become known as the sunshine vitamin.
How Do I Know How Much Vitamin D I Should Take

- âVitamin D2 is plant-derived and is preferred by those following a vegan diet.
- Vitamin D3 is typically derived from fish or sheep lanolin.
While both forms will help boost your bodyâs stores, D3 is twice as effective.âµ
The National Institutes of Health recommend 600 international units daily for most adults,ⶠbut research suggests that wonât stave off vitamin D deficiency.â· Recommendations from vitamin D experts range from 5,000 to 10,000 IU daily, or even higher.⸠Itâs unlikely youâll overdo it on the sunshine vitamin, but there is a small risk of toxicity called hypervitaminosis D if you do take too much.

Best Vitamins To Take With A Meal
You should take fat-soluble vitamins with meals or snacks that contain fat, such as avocado, egg yolks, or olive oil, for proper absorption.
Taking these vitamins with food ensures the optimal release of bile and pancreatic enzymes in the stomach that are required for the absorption of fat-soluble vitamins, Marinov says.
For some people, it makes the most sense to take these vitamins with a meal, like lunch or dinner, but you don’t necessarily have to, Stephenson says. Any food with some fat, like hummus or a handful of nuts, can help break down these vitamins.
Other supplements that should be taken with food include:
- Calcium carbonate. This is because the stomach acid produced when you eat helps your body absorb this type of calcium. Calcium citrate on the other hand can be taken with or without food, so be sure to check the label to see the kind of calcium your supplement contains.
- Multivitamins. These contain both water-soluble and fat-soluble vitamins, so take with food to ensure the fat-soluble vitamins are absorbed.
- Magnesium. Taking magnesium on an empty stomach has a laxative effect and may cause diarrhea.
The Vitamin D Deficiency Crisis
Vitamin D deficiency is rife across the globe, particularly in the United States.
When we consider vitamin D s vast array of health benefits, and its ability to ward off nasty diseases, it’s shocking to learn that approximately 40% of the American population suffers from a vitamin D deficiency.
This staggeringly high statistic largely comes down to a lack of sun exposure and ow consumption of vitamin D-rich foods.
It, therefore, comes as no surprise then that dietitians often recommend vitamin D supplementation.
However, there is a such a thing as too much vitamin D – known as Vitamin D Toxicity.
If you’re concerned that you’re getting too much or too little vitamin D, it’s worth checking in with your doctor and measuring your vitamin D levels.
Toxicity is caused by having too much vitamin D in the system, which can lead to a condition called hypercalcemia .
Regardless, if you’re concerned that you’re getting too much or too little vitamin D, it’s worth checking in with your doctor and measuring your vitamin D levels.
