Vitamin D Supplements – Which Work and Why?

Vitamin D is one of the most common supplements on the market. From strengthening skin, to boosting our immune system the list of benefits goes on and on. Check out this blog to find out why our skin needs vitamin D, and why your body may be deficient. We’ll also cover the best supplements on the market that you need to try.

What Is Vitamin D?

Vitamin D is a fat soluble vitamin that is naturally found in some foods. It is commonly known as the ‘sunshine vitamin’ as the body produces it in response to sun exposure.

Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients help keep skin, bones, teeth and muscles healthy and functioning normally.

From March and April to the end of September, most people are able to produce the correct levels of the vitamin D they need from sunlight. However, during the winter months we don’t make enough vitamin D due to a lack of sun exposure.

We can boost our vitamin D levels by adding supplements into our diets. Vitamin D supplements are increasingly important as many of us are staying indoors. We aren’t getting a healthy amount of sun exposure, especially due to COVID lockdown.

Why Is Vitamin D Important For Your Skin?

Vitamin D plays a vital role in protecting skin health. In its active form, vitamin D is calcitriol which aids skin cell growth, repair, and metabolism.

Vitamin D (or calcitriol) is also able to destroy free radicals that can cause oxidative stress and inflammation. A prolonged state of oxidative stress leads to the skin aging rapidly.

Free radicals are chemicals in the body which are oxidised. This means that they have lost an electron which then causes oxidative stress. This makes these free radicals unstable and highly reactive, leading to them oxidising everything that they come into contact with.

As well as being an anti-aging remedy, vitamin D supplements have also been found to aid skin problems such as acne and psoriasis.

What Causes Vitamin D Deficiency?

  • Lack of sun exposure
  • Staying indoors
  • Having darker skin
  • Lack of fish or dairy in the diet
  • Being overweight
  • Being an older adult
  • Health conditions that prevent nutrient absorption, such as Chrohn's disease
  • Gastric bypass surgery

Here’s Why You Should Avoid Most Over the Counter Vitamin D Supplements

Most regular vitamin D supplements that come in jars aren’t very effective. This is for 2 main reasons.

In order for a dietary supplement to be efficiently absorbed by the body, it must be both water soluble and oil soluble. This can be difficult to achieve. Most vitamins that come in tablet or gummy forms, aren’t created with this in mind.

This leads to the amount of vitamin D that is actually being absorbed into your body being dramatically decreased. Due to decreased levels of bioavailability, these tablets are largely ineffective and not cost efficient.

As well as this, opened jars are no longer airtight. This allows the dietary supplement to come into contact with the air and then oxidise. This reduces its effectiveness.

Why You Need Liposomal Supplements

Liposomal encapsulation is a drug delivery system that either facilitates absorption directly in the mouth or prevents the stomach acids prematurely breaking down the vitamin D.

Liposomal encapsulation involves the vitamin D being wrapped in liposomes, which are tiny bubbles of phospholipids. The liposomes shield, protect and deliver the supplements through the digestive system and into the bloodstream.

For effective vitamin D delivery, the nutrient needs to be both water and oil soluble. In Liposomal delivery, the supplements come in liquid form so have already been suspended in water.

The vitamins disperse and pass through our cell walls where they’re absorbed. This is possible as liposomes have a similar genetic makeup to the lipids found in our cells.

This aids bioavailability meaning that you’re getting a higher/more accurate dosage.

Without Liposomal delivery, it’s difficult for your body to absorb vitamin D supplements so avoid wasting your money on most tablet vitamins.

How Long Does It Take for Vitamin D Supplements to Work?

As vitamin D’s stored in fat cells, levels take longer to increase. For example, levels tested in April are more reflective of actual levels in January.

It is best to keep a consistent dosage up all year round rather than occasionally taking large doses. People tend to do this during the winter months. This is unless explicitly prescribed by a medical professional.

Most studies done on vitamin D supplementation do not include the use of Liposomal delivery.

This means that even though it makes logical sense that vitamin D would do better with this delivery method, there have been few clinical studies. Experts have reported better results with Liposomal delivery though when compared with tablets, capsules or gummies.

Which Supplements Are the Best?

Our expert dermatologists have found that the best brand currently on the market for liposomal supplements is YourZooki. The Liposomal Vitamin D Zooki has been uniquely tailored in order to maximise bioavailability and stability.

It also has added vitamin K2. This works together with the vitamin D to support the strength of our bones.

The Liposomal Vitamin D Zooki comes in liquid form which allows for more efficient and effective absorption. The airtight packaging also protects the product which prevents it from breaking down and oxidising. This means that you are actually getting the advertised dosage.

Unlike a lot of vitamin supplements, it also tastes great too. It’s flavoured with natural strawberry and blueberry extracts meaning you can take it on its own or add it to smoothies, yoghurt, or porridge.

YourZooki also take pride in using only 100% sustainably sourced and natural ingredients. They place emphasis on avoiding using additional ingredients such as potassium sorbate, sodium benzoate and alcohol. The Liposomal Vitamin D Zooki is also sugar free, gluten free, dairy-free, soy free and alcohol free.
