Vitamin D3 drops
Vitamin D3 drops in detail
Vitamin D is sunshine for your well-being – and support for your immune system*. There are many vitamin D supplements on the market – unfortunately, there are also many that work with inferior carriers such as palm oil and unnecessary fillers. We do things differently: our vitamin D3 drops contain high-quality ingredients such as cholecalciferol and sunflower oil - nothing else
*Vitamin D contributes to the normal function of the immune system.

Vitamin D3 plays a key role in calcium absorption and bone health. Combining it with vitamin K2 is indeed beneficial for bone function. If you want to combine vitamin D3 and K2, we also offer products that combine both nutrients. You have the flexibility to choose the supplement that best suits your individual needs.
It’s not critical when you take the drops, as long as it’s with a meal. Some experts recommend pairing them with your most nutrient-dense meal of the day.
When choosing the best vitamin D drops, quality matters – no unnecessary additives, and a manufacturer you can trust. Our BIOGENA Vitamin D3 drops are an excellent choice because they contain pure Vitamin D3 in the form of cholecalciferol and high-quality sunflower oil – no palm oil or low-grade oils.
Drops generally have a shorter shelf life than capsules or tablets, especially after opening. Store them in a cool, dry place, away from light and heat. Be sure not to touch the dropper with your skin or mucous membranes.
How quickly the drops work depends on various factors – such as your current vitamin D levels, the dosage, and your body weight. It can take several weeks to months to correct a deficiency. Your doctor can recommend the optimal dose after a blood test.
Vitamin D is fat-soluble, so it’s best to take your drops with a meal. The fat from the meal helps with absorption. Our vitamin D3 drops already contain sunflower oil to support this process.
At Biogena, “pure substance principle” means that we do not use technological additives which are used for the fully automated manufacturing of tablets, capsules and pills (e.g. anticaking or release agents and so forth) or additives that are used for optical reasons or for enhancing the taste of the products (artificial aroma, colouring agents, coatings etc.). Due to a semi-automatic manufacturing process, we can avoid these substances that often have a higher proportion in customary products than the actual active ingredients. In the case of nutritional supplements, additives have to be indicated in the list of ingredients. Here, the patient or customer can get useful information. Concerning the single ingredients, we also care for our raw materials to be free of carrier substances. In cases where this is not possible, we use natural food components such as maltodextrin, cellulose powder or calcium carbonate. The majority of our ingredients is produced exclusively for us – free of carrier substances (e.g. our enzymes our probiotics: other manufacturers often use lactose as a carrier – the product batches produced for us are explicitly without carriers).
