Vitamin D3 and the perfect combination. Boost your D3 with these partners

Untergehende Sonne scheint durch Kreis aus Zeigefinger und Daumen.

We all know how important vitamins are for our health. One of the key vitamins that deserves special mention is vitamin D3. It is often referred to as the 'sunshine vitamin' as our body can produce it itself under the influence of sunlight. However, in this day and age where many of us spend much of the day indoors, it can be challenging to get enough vitamin D3 naturally. This is where customized supplements from come into play to ensure you get the optimal amount of vitamin D3 tailored to your individual needs.

Vitamin D3 is not only crucial for bone health, but also plays a role in supporting the immune system, maintaining calcium levels and keeping the heart and muscles healthy. However, it cannot work alone, but should be combined with certain nutrients to maximize its effectiveness. At, we recommend the following combinations to realize the full potential of vitamin D3:

Vitamin K2: Vitamin D3 and vitamin K2 work in synergy to support bone health. Vitamin D3 helps to absorb calcium, while vitamin K2 helps to transport it to the right places, such as the bones, and keep it out of arteries and soft tissue. This interaction is crucial to prevent calcium deposits and support cardiovascular health.

Magnesium: Magnesium is another important partner of vitamin D3. It is involved in the conversion of vitamin D3 into its active form, which is essential for optimal utilization in the body. Magnesium also supports muscle and nerve function and contributes to relaxation, which is particularly important for reducing stress and promoting healthy sleep.

Omega-3 fatty acids: The combination of vitamin D3 with omega-3 fatty acids, especially EPA and DHA, is important for supporting cardiovascular processes. Omega-3 fatty acids have versatile properties and can help maintain normal blood pressure and contribute to the maintenance of your normal triglyceride levels. Linseed oil capsules are recommended for vegans and krill oil capsulesfor non-vegans.

Zinc: Zinc is an essential trace element that is crucial for the immune system. It can support the activation of vitamin D receptors, which in turn improves the effectiveness of vitamin D3 in the immune response.

Pantothenic acid: Pantothenic acid contributes to the normal synthesis and metabolism of vitamin D and some neurotransmitters.

The body's own production:
In naturopathy, vitamin D3 is often referred to as the "sun vitamin" because it can be produced by the body under the influence of sunlight.

The human body can actually produce vitamin D itself, and this process begins with exposure to sunlight. More specifically, it is the ultraviolet B (UVB) light in sunlight that plays a crucial role. When the UVB rays reach the skin, a precursor of cholesterol in the skin, called 7-dehydrocholesterol, reacts to the UVB light and is converted into the inactive precursor vitamin D3.

The further conversion into the active form of vitamin D3 then takes place in two steps. First, the inactive precursor vitamin D3 is transported to the liver, where it is converted into 25-hydroxyvitamin D3. Then, the final conversion to the active form of vitamin D, known as calcitriol, takes place in the kidneys.

Duration of sun exposure:
The time it takes to produce sufficient amounts of vitamin D through exposure to sunlight varies depending on individual factors such as skin type, latitude, time of day, season, clothing and use of sunscreen. People with lighter skin can produce vitamin D faster than people with darker skin, as melanin in the skin reduces the absorption of UVB rays.

As a rule of thumb, it is often recommended that daily sun exposure of around 15 to 30 minutes is sufficient to produce enough vitamin D. However, this time may vary depending on the geographical location. However, this time can vary depending on geographical location and time of year. In regions with less sun exposure, especially in the winter months, it may be more difficult to produce enough vitamin D through sunlight alone.

The role of sunscreen:
Sunscreen is an important tool for protecting the skin from harmful UV rays, especially the dangerous UVA and UVB rays that can cause sunburn, premature skin aging and the risk of skin cancer. While the use of sunscreen is highly recommended to protect the skin from damage, it can also affect the skin's ability to produce vitamin D3.

Most sunscreens have a sun protection factor (SPF), which indicates how well they protect against UVB rays. A higher SPF means stronger protection, but it has been shown that sunscreens with a high SPF can reduce the production of vitamin D3 in the skin. Therefore, it is recommended to expose yourself to the sun without sunscreen for a limited time in the early morning or late afternoon hours, when the sun is less intense, to support vitamin D3 production. However, it is important not to do this in the midday sun or expose yourself to the sun for too long without protection to avoid sunburn and other skin damage.

In conclusion, it is important to find a healthy balance between protecting yourself from harmful UV rays and ensuring that your body is getting enough vitamin D3. If the natural production of vitamin D3 through sunlight is not sufficient or is not enough due to specific needs, customized vitamin D3 supplements can be a useful supplement to meet individual needs and support health.
