Is Vitamin D Water or Fat Soluble?

is vitamin d water or fat soluble

Is vitamin d water or fat soluble? This is a crucial question for anyone looking to optimise their vitamin D intake.

The answer is clear: vitamin D is typically fat soluble. This is due to its composition using organic fatty oils such as olive oil, coconut oil and MCT oil.

Because of its innate ability to dissolve in organic solvents, this means vitamin D can be easily absorbed along with dietary fats found in certain foods such as salmon and avocados. Overall, these elements critically influence how your body absorbs and stores this essential nutrient.

Drawing from our experience, vitamin D supplements work best when taken with naturally fatty foods, as they help more significantly with absorption in contrast with fat-free meals.

In this guide, we at Vitamart will explore the nature of vitamin D solubility, compare water-soluble and fat-soluble vitamins, discuss the benefits of vitamin D supplementation, and answer common questions about vitamin D quantities.

What this article covers:

Is Vitamin D Water or Fat Soluble?

Through our practical knowledge, we know that vitamin D is inherently fat-soluble, making it unique among vitamins.

When you take a fat-soluble vitamin like vitamin D, it gets absorbed along with fats in your diet and stored in your body's fatty tissues for extended periods.

This storage capability means you don't need to take it as frequently as water-soluble vitamins and your body utilises it whenever necessary.

But is vitamin D a hormone as well? Interestingly, vitamin D functions as both a nutrient and a hormone in your body.

After being synthesised in the skin via direct contact with sunlight or orally ingested, it's then converted into calcitriol, which is its active form. This helps with regulating calcium and phosphate levels, positively influencing your bone health and immune function.

This dual role makes vitamin D especially important for Canadian residents, who often struggle to get enough intake due to our long winters and limited sun exposure.

Water-Soluble vs. Fat-Soluble Vitamins: What's the Difference?

Here are some more key differences between water-soluble and fat-soluble vitamins.

Table: Water-Soluble Vs. Fat-Soluble Vitamins

Characteristics

Water-Soluble Vitamins

Fat-Soluble Vitamins

Absorption

  • Dissolves in water
  • Absorbed directly into the bloodstream
  • Absorbed alongside natural fats
  • Requires bile and enzymes for proper absorption​
  • Softgels made using vitamin D and fatty oils like olive oil, coconut oil or MCT oil for optimal absorption

Storage

  • These vitamins aren't stored in large quantities in the body
  • Must be replenished regularly through diet
  • Excess amounts are typically excreted through urine
  • These vitamins can be stored in the liver and fatty tissues over long periods
  • Provides a reserve for future use​

Excess

  • Less likely to accumulate to toxic levels due to sufficient excretion
  • Excess consumption of certain vitamins can still result in side effects such as diarrhoea and nausea
  • Pose a higher risk of toxicity when taken in large doses

Daily intake

  • Must be consumed more frequently because they aren't stored in the body for long
  • Can be taken less often since the body maintains reserves for longer

Examples

  • Vitamin C
  • Vitamins B1, B2, B3, B5, B6, B7, B9, and B12

Water-Soluble Vitamins

Water-soluble vitamins play critical roles in energy production and immune support.

Water-soluble vitamins, including vitamin C and the B-complex group, are absorbed directly into the bloodstream without being stored in significant amounts by the body.

As such, they must be consumed regularly through your diet to avoid deficiencies. Excess quantities are typically excreted through urine, making toxicity rare.

Fat-Soluble Vitamins

Fat-soluble vitamins like a vitamin D supplement are absorbed along with fats from your diet and can be stored in your liver and fatty tissues for extended periods.

The best vitamin D supplements are those that come in forms that optimise this fat-soluble nature. For example, a vitamin D softgel comprises a fatty oil base commonly made with either olive oil, coconut oil or MCT oil to better aid the body's absorption process.

Can you take vitamin D on an empty stomach? Unlike water-soluble vitamins, which can be taken any time, vitamin D absorption is better enhanced when taken with larger meals as well as food and drinks containing natural fats like mushrooms and fortified milk.

Benefits of Vitamin D Supplements

As per our expertise, we know that vitamin D and vitamin D3 through supplementation offer numerous benefits, particularly for Canadians.

During our long winters, when sunlight exposure is limited and seasonal affective disorder (SAD) is likely to occur, supplements become crucial for maintaining ideal vitamin D levels.

These benefits typically include:

  • stronger bones and teeth
  • enhanced immune system function
  • improved mood and mental well being
  • better muscle capability

Vitamin D Fat or Water Soluble FAQs

Can Fat-Soluble Or Water-Soluble Vitamins Cause Weight Gain?

Neither fat-soluble nor water-soluble vitamins directly cause weight gain, as vitamins don't contain calories.

With that said, fat-soluble vitamins, like vitamin D, are stored in the body's fat tissues. This can potentially affect how long they remain in your system without necessarily contributing to weight gain.

It's essential to follow recommended dosages, as excessive quantities of fat-soluble vitamins can lead to toxicity. On the other hand, deficiencies in certain vitamins can lead to poor appetite, indirectly affecting weight changes​.

Is It Possible To Get Too Much Of Water-Soluble Vitamins?

Based on our observations, water-soluble vitamins are generally safe to consume. This is due to the body's ability to excrete any excess amounts through urine.

However, high doses can still lead to adverse effects. For example, taking too many vitamin C supplements can lead to digestive issues like diarrhoea and nausea.

Similarly, excessive vitamin B6 can result in nerve damage. This can cause numbness and muscle control issues, especially when taken in supplement form over long periods of time.

What Happens If You Don't Get Enough Fat Soluble Vitamins?

Insufficient intake of fat-soluble vitamins, particularly vitamin D, can lead to various health issues, including osteoporosis and heart disease.

Moreover, vitamin D deficiency is especially common for Canadians during winter months, potentially causing:

  • weakened bones and pain
  • compromised immune function
  • increased fatigue
  • mood changes
  • muscle weakness
