The Current Market Leaders in Vitamin D3 Plus K2 Supplements

Discover the top contender among Vitamin D3 plus K2 supplements. As dietary supplements with Vitamin D grow in popularity, it’s worth taking a closer look at the wide range of products available. Our recommendation: choose only the highest quality supplements, as your health is at stake.

Vitamin D may be familiar to you as the “sunshine vitamin.” This comes as no surprise, as the body’s production of this compound is primarily stimulated by UV-B radiation. This makes it quite unique: Vitamin D is the only vitamin that the human body can produce on its own. Because of this, it technically isn’t even a vitamin – but more on that later.

Rather than being a single substance, Vitamin D refers to a group of fat-soluble molecules known in scientific literature as calciferols. The most important form is Vitamin D3, also known as cholecalciferol.

Vitamin D is best known for its involvement in bone metabolism. It promotes the absorption of calcium and phosphate from the intestine and supports their integration into bones, playing a key role in bone mineralization.

The human body typically produces 80–90% of its Vitamin D through exposure to sunlight [1]. To maintain sufficient levels, it’s important to spend as much time outdoors as possible, as indoor lighting cannot stimulate production.

Surprisingly, diet only contributes 10–20% of Vitamin D supply. This is partly because foods rich in Vitamin D are rarely consumed in the United Kingdom.

Examples include:

• Fatty fish
• Cod liver oil
• Certain mushroom varieties

Especially people who mostly work in an office often struggle to spend enough time outside in the sun, making Vitamin D often used as a dietary supplement.

What makes the combination of vitamin D3 and K2 so special

Vitamins D and K form a powerful duo. Together, they support numerous metabolic processes, contributing to overall well-being. Vitamin D is particularly known for its role in maintaining healthy bones, normal calcium levels in the blood, and proper immune system function [2].

Additionally, Vitamin D contributes to:

1. Cell division processes.
2. Maintenance of healthy teeth.
3. Normal muscle function.

Vitamin K also performs a number of vital functions in the body, playing a crucial role in supporting normal blood clotting, and like its “partner” vitamin D, it also contributes to the maintenance of normal bones. This synergy explains why Vitamin D3 and K2 complement each other so well and are often combined in supplements. However, as with practically all compounds, misconceptions about this combination persist.

Myths about vitamin D3 and K2: These rumors persist

Whether it’s food, vitamins or medication: there are rumors about almost every conceivable product. It would be unusual if this were different for vitamins D3 and K2. These rumors persist to this day, even though they have long been scientifically disproven.

Myth 1: Vitamin D and K2 can be adequately obtained through food

As previously mentioned, only a small amount of vitamin D is ingested through food.

This is primarily because very few foods contain significant amounts of Vitamin D, and these particular foods are consumed infrequently in the United Kingdom. Therefore, achieving sufficient Vitamin D intake through diet alone is generally not feasible.

Additionally, in our geographical region, there is often insufficient sunlight to adequately stimulate the body’s natural production of Vitamin D. Even during the summer months, unfavorable weather conditions can reduce UV-B radiation by up to 90% [1].

Although Vitamin K is found in a wider variety of foods (especially green vegetables such as broccoli, spinach, and kale), not everyone is able to meet their needs through their diet. Especially during stressful periods, people tend to eat less fruit and vegetables, making Vitamin K2 supplementation useful [3].

Myth 2: Vitamin D is easily overdosed

Although Vitamin D can be overdosed, but this would require consuming very large amounts far exceeding the manufacturer’s recommendations. An article in the Pharmazeutische Zeitung from the summer of 2022 describes a case where a person took 150,000 IU daily and experienced various symptoms [4]. The standard dosage available on the market typically ranges from 1,000 to 5,000 IU. Therefore, a quick overdose is unlikely as long as you stick to the dosage recommendations provided by the manufacturers.

Myth 3: The combination of vitamin D and K offers no real benefits

It has been scientifically proven that the combination of both vitamins is associated with various benefits for the body. Studies show a particularly beneficial effect for the skeletal system, as both vitamins contribute to maintaining normal bones [2, 5].

Surprising facts about vitamins D and K that you probably didn’t know

Many things are known about vitamins D and K, but these facts may surprise you:

Fact 1: Vitamin D is actually not a vitamin

The fact that the body can produce Vitamin D itself is unusual for something classified as a “vitamin.” In reality, it is technically a hormone. Why, then, is it not considered a vitamin? The answer lies in the definition: a vitamin is defined as an essential organic compound that the body cannot produce on its own [6]. However, the body can produce Vitamin D – as long as it receives enough sunlight.

Fact 2: Vitamin K and D deficiencies manifest through very different symptoms

Although Vitamins K and D are similar in their function, the symptoms of a deficiency in each are quite different.

Common symptoms of Vitamin D deficiency are:

• Muscle weakness
• Muscle and joint pain
• Fatigue and exhaustion
• Depressive moods (e.g., seasonal depression)
• Increased susceptibility to infections
• Excessive hair loss

In contrast, insufficient Vitamin K supply is more likely to present as:

• Increased tendency to bleed from wounds
• Easy bruising
• Gum bleeding
• Difficulty concentrating
• Lack of motivation
• Headaches
• Internal bleeding (in severe cases of deficiency)

Fact 3: Vitamin D production decreases with age, even with sufficient sunlight

As we get older, our body’s ability to produce Vitamin D declines. People over the age of 65 are particularly at risk for Vitamin D deficiency and should monitor their levels closely [7]. If you fall into this age group, it’s a good idea to discuss this topic with your GP.

You should pay close attention to these points when buying your combination product

If you’re considering using a combined Vitamin D and K supplement, it’s crucial to prioritize high quality. The market for dietary supplements is so vast that it’s easy to lose track. However, since this concerns your health, you should make no compromises when it comes to quality.

An ideal combined supplement should meet the following criteria:

• Sufficiently high doses of Vitamin D and Vitamin K
• Vitamins are in their natural forms
• Free from chemical additives
• High bioavailability and bioactivity of ingredients
• Capsule form (for best possible Vitamin D absorption)
• Free from allergens
• Contains no animal-derived components, making it suitable for vegans

The following paragraphs will show you which product best meets these high expectations.
