Although we’re all aware of vitamin D, it is far from being at the forefront of our minds - and even further from being in everyone's nutrient supply. Looking at current data, large parts of the population could benefit from vitamin D supplements. However, the market for vitamin D preparations is confusing and it can be tricky to make the right choice. Whether single or combination preparations, the BIOGENA vitamin D product range offers the right dosage for every individual’s needs. For vegetarians or vegans, a purely plant-based vitamin D raw material from lichens is an ideal option for a year-round supplementary supply of sun vitamin. As a premium manufacturer, BIOGENA stands by the pure substance principle, doing without unnecessary additives. It also follows uncompromising quality standards, which result in good tolerability and high bioavailability.
Vitamin D as a nutritional supplement
At BIOGENA, every single vitamin D preparation is unique. From our use of innovative NutriGellets® technology to optimize bioavailability to the addition of high-quality linseed oil, or the combination with cofactors of vitamin D metabolism such as magnesium - we have something for everyone here.
Capsules, tablets, effervescent tablets, or liquid? What are the best dosage options?
Vitamin D is available on the market in various forms - from capsules to tablets, effervescent tablets, or liquid drops. Capsule products, which are manufactured to the BIOGENA standard, make it possible to dispense with unnecessary additives such as colorings, binding and separating agents, or synthetic coatings. High-dose vitamin D in capsule form is particularly suitable for weekly supplementation as a practical alternative to a daily intake. The positive synergistic effects of vitamins D3 and K2 are the focus of current science and research, which has led to the development of the micronutrient preparation BIOGENA Vitamin D3 & K2. Vitamin K, like vitamin D, supports the maintenance of normal bones and is therefore a useful addition to vitamin D supplementation.
Vitamin D3 drops: Vitamin D is also available in liquid form, which allows for even easier application as well as variable dosage. The drop preparations from BIOGENA have a neutral taste and avoid medium-chain triglycerides from palm oil. In addition, drop preparations are a fantastic alternative for people who are unable to swallow capsules.
Vitamin D for children
For this reason, drops are particularly popular with children - Junior Vitamin D3 is ideal.
What is the best way to take Vitamin D?
Vitamin D can be taken at any time of day - but it is important to combine it with a meal. Since vitamin D is fat-soluble, fatty acids in the food support its absorption into the body.
The 3 Basics of Vitamin D Care
We would like to give you three facts that can help you ensure a stable vitamin D level in all situations:
- The body can form vitamin D itself using sunlight. Adequate UV B radiation must be ensured in this case. A tip from the editor: Most weather apps also provide information about the current UV index.
- For the body’s vitamin D self-synthesis, one-quarter of the skin (face, hands, parts of the arms and legs) must ideally be exposed to the sun daily from March to October between 12.00 midday and 3.00 in the afternoon, without sunscreen, for 5 to 25 minutes (depending on the time of year and the skin type).
- In the case of a low vitamin D status and insufficient self-synthesis due, for example, to insufficient time spent in the sun under ideal conditions, the use of a vitamin D supplement is recommended.
Frequently Asked Questions about Vitamin D
Certain groups should pay special attention to their vitamin D intake. Older adults, for example – as skin loses up to 50% of its ability to produce vitamin D with age. If you rarely get outside during peak sun hours, your body might not make enough on its own. People with darker skin tones also produce less vitamin D, putting them at greater risk of deficiency – especially in Central and Northern Europe. Pregnant and breastfeeding individuals need extra support to ensure a healthy supply for both parent and child. And for infants, whose skin should be kept out of direct sunlight, a vitamin D supplement is a definite must-have.
Not sure if your vitamin D levels are sufficient? A simple blood test can give you clarity.
We recommend Biogena Vitamin D 2000 DUO, Vitamin D3 drops, Vitamin D3 2000 vegan or Vitamin D3 15.000. Biogena can also offer the combination of vitamin K and vitamin D, namely Biogena vitamin D3 & K2.
Vitamin D isn’t just one nutrient – it’s a whole family of fat-soluble compounds known as calciferols. Within this group, vitamin D3 (cholecalciferol) plays the leading role – it’s the most effective form your body can actually use.
In some cases, taking vitamin D on its own makes more sense – for example, if your personal need for vitamin K2 is low, you’re on blood-thinning medications, or you have certain kidney conditions. For lower vitamin D dosages or specific therapeutic goals, a separate intake may be the better option. Not sure what’s right for you? It’s always best to check in with your doctor.
Absolutely – omega-3 fatty acids and vitamin D are a perfect match! They support your health in different ways and don’t interfere with each other. In fact, taking vitamin D with a fat source like omega-3 can even improve absorption. A smart combo for your daily wellness.
