Millions spend long periods indoors or work in sunlight-restricted setups, while for others, lifestyle factors restrict sunlight exposure. These issues limit the scope of natural vitamin D generation through the skin.
Similarly, vitamin D supplementation may not always increase vitamin D absorption. Factors like the form of Vitamin D, cofactors, and dietary fat consumption also play key roles.
Vitamin D is a fat-soluble vitamin. So, the way the nutrient is used in the formulation and processed in the body affects absorption. A formulation carrying a healthy fat base like carrier oil can support better vitamin D absorption in the body. VitSupp, for example, has an MCT oil base, which supports nutrient absorption. Its unique Vitamin D3 + K2 formula has been tested extensively for absorption as well as safety.
This blog explores the factors affecting vitamin D absorption and the proven ways to improve absorption. It also shows how VitSupp’s offering supports absorption of this vitamin in a safe and balanced way.
Why Vitamin D Levels Can Stay Low Even in Sunny Regions?

Why do people cope with low vitamin D levels even in sunny regions?
1. Lack of enough time spent outdoors per day.
2. Sunscreen usage may lower skin-level vitamin D synthesis.
3. Wearing protective clothing outdoors may lower sunlight-based vitamin D generation.
4. Rising pollution and dense airborne particles may limit the mechanism of UVB rays on skin.
Your body needs direct exposure to UVB light for natural vitamin D generation. However, millions struggle to get vitamin D through sunlight for the following reasons:
- They can’t spend much time outdoors to get sunlight on a daily basis.
- The use of sunscreen limits vitamin D synthesis, according to major study findings.
- Those wearing protective clothing outdoors may also cope with similar issues.
- In urban regions, growing pollution levels reduce the efficacy of UVB rays for vitamin D generation.
This is why people living in sunny environments may cope with low vitamin D levels.
Other Factors Affecting Vitamin D Absorption
Remember that sunlight is only one part of the Vitamin D creation and function. After your skin processes vitamin D through sunlight or you obtain it through food or supplements, it undergoes conversions before reaching the active form. Notably, Vitamin D gets converted in the liver and kidneys to turn into a usable form. This processing may not happen equally in all users, and those with existing digestive conditions may cope with poor absorption and processing.
To improve vitamin D levels, you should look beyond sunlight exposure and focus on modifying lifestyle habits and dietary intake. Using Supplementation can help, but choosing the right formulation is crucial. Clean-label supplements with highly bioavailable sources like Lichen can be ideal for vitamin D absorption in the body.
How Does Vitamin D Absorption Work in the Body?
When you consume Vitamin D through food or supplements, it is absorbed in the intestine. Dietary fat is one of the factors affecting vitamin D absorption.
After absorption, Vitamin D enters the bloodstream and reaches the liver. There, the first metabolic conversion takes place. Subsequently, it undergoes conversion in the kidneys into its active form, called calcitriol (1,25-dihydroxyvitamin D). This is the biologically functional form that regulates several physiological processes.
Just consuming a certain amount of Vitamin D is not enough for absorption. A supplement may contain a specific amount of Vitamin D. However, the body’s ability to absorb and process that Vitamin D depends on several factors, like digestion, metabolism, and the formulation used. VitSupp uses a formulation containing both MCT oil and 95% piperine extracts, ingredients that may support nutritional absorption.
Choosing the Right Form of Vitamin D: Why D3 Matters
Do not think of Vitamin D as a single compound. Among the different forms, Vitamin D2 and Vitamin D3 are the major ones found in supplements and dietary sources. Consuming both of these forms may add to your Vitamin D levels. However, your body processes and converts them in different ways.
Vitamin D2, or ergocalciferol, commonly found in plant and fungal sources, is also used in supplements and fortified foods. Vitamin D3, or cholecalciferol, is the form your skin generates when exposed to UVB light. Also, it is extensively used in supplements.
Research comparing these forms indicates that Vitamin D3 may be more effective than Vitamin D2 at improving and maintaining blood levels of Vitamin D. An American Journal of Clinical Nutrition review showed that Vitamin D3 supplementation fares better at increasing serum 25-hydroxyvitamin D concentrations than Vitamin D2.
However, the efficacy of a vitamin D supplement does not depend only on the Vitamin D type. Factors like dosage, consistency, absorption, and individual Vitamin D status have an effect on the final outcome.
Vitamin D supplements use IU to denote the amount of the nutrient per dose. While 600 IU of Vitamin D is often taken as a reference intake level for adults, individual intake needs can vary. Factors like users’ age, Vitamin D level, sunlight exposure, diet, and health conditions matter.
To choose the right Vitamin D form, don’t go by numbers alone. Selecting a clean-label vitamin D3 supplement with RDA-level dosage is recommended. VitSupp’s offering does that and also has a well-researched formulation focused on vitamin D absorption and safety.
Taking Vitamin D With the Right Food for Better Absorption
Vitamin D absorption depends on what you consume it with, apart from the chosen form. For better results, choose specific types of foods to increase vitamin D absorption. Keeping some dietary fat in the meal can be useful here. For healthy fats, you can try consuming foods like egg yolks, dairy products, nuts, seeds, etc.
A study published in the Journal of the Academy of Nutrition and Dietetics showed that taking Vitamin D with fat-containing meals improved serum 25-hydroxyvitamin D levels over a fat-free meal. So, consuming a Vitamin D supplement along with a healthy fat-based meal may support better absorption compared to taking it on an empty stomach.
Food, Fortified Sources, and Sunlight – for Better Vitamin D Absorption
To support vitamin D absorption in the body, focus on the key sources. Sunlight is a major natural source, but don’t undermine the role of dietary intake to maintain Vitamin D levels.
While the body generates Vitamin D through sunlight exposure, the amount produced depends on nuances like location, season, time spent outdoors, exposed skin, and lifestyle habits. People using and not using sunscreen may have different Vitamin D levels even if they live in the same city, for example.
You can get vitamin D through foods, though the sources are rather limited. The well-known natural food sources of Vitamin D include fatty fish, egg yolks, and certain types of mushrooms exposed to UV light. You may also try foods fortified with Vitamin D.
For millions of Indians, getting the daily dose of Vitamin D needs through diet alone can be tough. It is tougher for vegans and vegetarians who have fewer natural food sources for this vitamin.
A well-designed supplement can help them deal with nutritional gaps related to diets and lifestyle issues. VitSupp’s unique Vitashine Vegan D3 + BioEssence K2 MK-7 formulation is designed to support and improve vitamin D absorption. Made in a vegetarian HPMC capsule, it does not contain unnecessary fillers (soy or gluten, etc) or any animal extract at all.
Does Supplement Formulation Affect Vitamin D Absorption?

Does supplement formulation impact vitamin D absorption?
1. Why does vitamin D formulation matter?
2. Why include Vitamin K2 in the formulation?
3. What cofactors are important and why?
Don’t focus solely on the amount of Vitamin D listed on the label when buying a supplement. The vitamin form (D3 or D2), delivery method, and supporting ingredients play a role in vitamin D absorption in the body. Two supplements may include similar IU of Vitamin D, but their formulations may differ, and that may eventually affect absorption and processing.
Why Vitamin D3 Formulation Matters?
Check the type of Vitamin D used in supplements before ordering. While there are many sources, lichen-based Vitamin D3 is ideal for those adhering to vegan diets. They cannot take supplements containing lanolin.
What’s the Benefit of Including Vitamin K2?
Some Vitamin D3 supplements also include vitamin K2, and for a reason. Both these nutrients are involved in calcium-related processes. While Vitamin D supports calcium absorption, Vitamin K2 supports sending the absorbed calcium to bones and not to soft tissues. VitSupp offers Vitamin K2 (MK-7) form in its formulation to support calcium regulation.
The Importance of Cofactors
Since Vitamin D is fat-soluble, some supplements contain healthy fats and cofactors in the formulation to support vitamin D absorption. In VitSupp, for example, you get supporting ingredients like Piperine and MCT oil, both having potential bioavailability-enhancing properties. These complementary ingredients have been chosen thoughtfully.

Things that affect Vitamin D levels and absorption
1. Digestive health conditions
2. Age, body type, and health metrics
3. Consistency in supplementation
The human body’s ability to absorb, transport, and process Vitamin D can vary based on specific factors. That’s why two people taking the same supplementation can have varying Vitamin D levels.
1. Digestive health affects vitamin D absorption. Health conditions affecting fat digestion or absorption may have an effect on the vitamin D absorption mechanism. Those with conditions like celiac disease, IBD, and Crohn’s disease may face issues in vitamin D absorption, according to studies.
2. Age, body composition, and certain health conditions may also affect vitamin D levels. Higher body weight and aging, in particular, limit vitamin D synthesis through sunlight and absorption.
3. Consistency is crucial for maintaining Vitamin D levels. For better absorption, you need to adhere to a vitamin D-rich diet consistently. The same logic applies to supplementation, as per guidelines.
Before choosing a vitamin D supplement for better absorption, analyzing these factors is recommended.
Conclusion
To maintain healthy Vitamin D levels, you need not focus on consuming a larger amount of Vitamin D. The body acquires Vitamin D from multiple sources, and absorption and processing depend on several interrelated factors. Your health conditions, dietary fat intake, and lifestyle habits come into the picture.
To address dietary deficiency and lifestyle -related vitamin D absorption issues, using supplementation can be useful. However, be careful about the formulation details and safety.
VitSupp’s study-backed Vitamin D3 + K2 formula is focused on bioavailability, and it undergoes stringent testing for safety. The manufacturing process has the approval of FSSAI, and the vegan HPMC capsules are made in a GMP-class facility.

5. Does Vitamin D3 (cholecalciferol) absorb better than Vitamin D2?
Vitamin D3 (cholecalciferol) and Vitamin D2 (ergocalciferol) are both common in supplements. However, research suggests that Vitamin D3 is potentially more effective than Vitamin D2 at improving and maintaining blood levels of Vitamin D. The former is better at increasing serum 25-hydroxyvitamin D concentrations, according to the findings. However, remember that certain factors affecting vitamin D absorption may have an impact on final numbers. Factors like dosage, consistency of intake, and health conditions also affect Vitamin D status.
6. What helps your body absorb Vitamin D more effectively?
Vitamin D absorption depends on numerous factors.
When you take vitamin D-based food with healthy dietary fat, that supports absorption since the vitamin is fat-soluble, a study shows consuming the vitamin with the largest meal of the day, alongside dietary fat, helps improve serum 25-hydroxyvitamin D levels, in comparison with consuming it with a fat-free meal.
When you take vitamin D supplements, the presence of supporting ingredients, like MCT oil, can support absorption.
7. Does taking Vitamin D with fat improve absorption?
Yes, when you take Vitamin D with a meal containing fat, that may support absorption. Vitamin D’s fat-soluble nature makes it absorb better with dietary fats during digestion. You can include various sources of healthy fats, including egg yolks, nuts, seeds, and dairy products, to support this process. However, remember that using dietary fat is just one aspect of vitamin D absorption in the body. Things like your consistency of intake, form of vitamin D, sunlight exposure, and individual Vitamin D metabolism also play their roles in absorption.
8. Should you take Vitamin D with food or on an empty stomach?
It is advisable to take Vitamin D with a meal rather than on an empty stomach. As the vitamin is fat-soluble, taking it with dietary fats can support the absorption and subsequent conversion in the body. Ideally, you can take it with the largest meal of the day to experience a growth in serum 25-hydroxyvitamin D concentrations.
9. How long does it take the body to absorb vitamin D?
The time needed by the human body to absorb and process Vitamin D can vary. The factors affecting vitamin D absorption duration are vitamin D type, dietary fats, existing Vitamin D levels, health conditions, etc. Notably, after absorption, vitamin D gets processed in the liver and kidneys. After that, it gets converted into its active and usable form. Those seeking to improve their vitamin D levels should focus on checking blood levels of 25-hydroxyvitamin D over immediate absorption.
10. What should you look for in a highly absorbable Vitamin D supplement?
Do not go by only the amount of vitamin D per dosage ( in IU) when choosing a supplement for better absorption. Analyze key factors like vitamin D form, formulation, the ingredient source, dosage, etc. Vitamin D3 is deemed more effective than Vitamin D2 at raising Vitamin D levels. Also, supplements like VitSupp that contain healthy fats like MCT oil in their formulation may support the vitamin D absorption mechanism. Also, read the label for details on bioavailability and ingredients that may support absorption, like piperine extract.
