You have probably heard a lot about vitamin D3, as it is often called the "sunshine vitamin". The body can absorb the vitamin from food as well as produce it itself with the help of sunlight. It has many important functions in the body and strengthens our immune system.

So if you can't spend hours in the sun, you can take vitamin D3 drops as a dietary supplement. Due to the popularity of dietary supplements, we have created this guide to provide extensive knowledge about vitamin D3 drops. We are pleased that you are interested in our vitamin D3 drops test 2022 and would like to show you how to find the right vitamin D3 drops for you.




Summary

  • The dosage of vitamin D3 drops should always be followed carefully, as side effects can occur. In the case of high-dose products, a doctor should also be consulted before use. However, a dosage of up to 1000 I.U. per drop should be sufficient for daily use.
  • In terms of quality, the so-called pharmacy quality is optimal, as it denotes a bacterial-free and pure product that has been produced according to medical standards and food guidelines. German manufacturers are also obliged to list all ingredients and obtain certification from laboratories.
  • Vitamin D3 drops are available in high-dose form, without additives, gluten-free or suitable for children. The quality and origin of the vitamin is crucial. Manufacturers often vary here and add other substances for compatibility in the body. Therefore, pay close attention to the ingredients on the packaging.

The Best Vitamin D3 Drops: Our Picks

Buying and Evaluation Criteria for Vitamin D3 Drops

There are a number of things to consider before buying vitamin D3 drops. Here we have listed the most important criteria:

Choosing the right vitamin D3 drops for you will save you time and money and give your body the optimal vitamin D3 supplement it needs.

In addition to the price, it is important that you also pay attention to high-quality processing and certified quality. If necessary, ask the manufacturer for the relevant certificates.

Dosage

The dosage is expressed in concentration per drop. Normally, this is 1000 I.U. per drop, but in the case of products for children it should be much lower, rather 800 I.U.. In the case of high-dose vitamin D3 drops, a dosage of up to 5000 I.U. per drop may be possible (I.U. stands for International Unit).

You should consult your family doctor before taking the drops to avoid undesirable side effects. High-dose drops are generally more expensive than, for example, drops for children. It is also advisable to pay attention to the purity of the product, as additives in the drops can often influence the dosage and the price.

Additives

Here you can choose between additional oils and fats that can accelerate the absorption of vitamin D3 in the body and other vitamins such as K2. This vitamin mix has the advantage of having two different vitamins in one bottle, which is also reflected in the price.

There are also vegan alternatives for vitamin D3 drops that come from purely vegetable sources and do not contain any artificial additives. From gluten-free to lactose-free and GMO-free, you will find a wide selection of vitamin D3 drops here. However, always pay attention to the quality and origin of the raw materials.

Origin

With German manufacturers, you can be sure that you are getting a high-quality, pure and certified product in pharmacy quality due to strict requirements and constant controls in independent laboratories. A short transport route also allows for a longer shelf life of your product.

Always check the ingredients on the back of the packaging and make sure they are of pure natural origin.

If you don't know the name of a product, look it up on the internet and find out more about it. This will prevent side effects due to possible intolerances and you will enjoy your product more.

Quality

The differences in quality can already be seen in the price. High-dose, pure, high-quality vitamin D3 drops are usually much more expensive than low-concentration drops with additives. Check the certification on the packaging and always contact the manufacturer directly if you have any questions.

The term "pharmacy quality" means that this is a particularly pure and bacteria-free product that meets both medical and food standards. This is a good indication of quality and guarantees a long shelf life and safe use of the product.

Guide: Frequently asked questions about vitamin D3 drops answered in detail

In the following sections, we have compiled all the information you need about vitamin D3 drops and summarised and answered important questions. We specifically address the mode of action, application and dosage of vitamin D3 drops to give you a comprehensive understanding before using the product.

What are vitamin D3 drops and how do they work?

Vitamin D3 drops are vitamin D3 in liquid form. They are easy to dose and can also be taken with additives such as oils or fats. Vitamin D3 has an effect on different parts of the body. Here we have listed the three most important effects of vitamin D3.

Effect on osteoporosis

Vitamin D3 plays a decisive role in the treatment of osteoporosis. It strengthens the bone structure and stimulates the muscles, supporting the general strength and functionality of the body. Increased bone density effectively reduces the risk of falls in osteoporosis patients by up to 20 percent and prevents fractures.

Effect in bedridden patients

Whether due to illness or other reasons, sometimes you can't make it out into the fresh air and sunshine. In this case, vitamin D3 drops can easily help to compensate for the lack of sunlight, which is so important for the body's own vitamin D3 production.

Especially in the autumn and winter months, a study showed that adults in Germany often suffer from vitamin D3 deficiency, which may also be due to a lack of exercise and a high-fat diet.

Effect on dark skin types

For people with darker skin types, it can be beneficial to take additional vitamin D3 drops, as their skin has a higher melanin content than lighter skin.

This makes it harder for the skin to absorb the sun's UVB rays, which are crucial for vitamin D3 production. To compensate for this, vitamin D3 drops are best as they are easy to dose.

When and for whom is it useful to take vitamin D3 drops?

The time of taking vitamin D3 drops is not exactly determined, which is why you can take the food supplement in the morning, at noon or in the evening. However, vitamin D3 is fat-soluble and should therefore be taken with something fatty. This can be coconut oil, for example, which enables rapid absorption in the body.

It may be useful to take vitamin D3 drops for the following groups:

  • People with dark skin
  • People who cannot get much sunlight outside.
  • People with osteoporosis or rickets
  • Elderly people with joint or bone problems

However, for all other people, without health complaints, it is shown that taking vitamin D3 with a dosage of 50-100 μg, with a normal daily routine with sunlight hours and a balanced diet, has no effect on the body. Here it is rather unnecessary to supply the body with additional vitamin D3.

Contrary to the general assumption that vitamin D3 should also increase performance during sports activities, studies have only found a slight improvement in endurance, but no increase in strength or power.

How can I tell if I have a vitamin D3 deficiency?

To test the exact amount of vitamin D3 in your body, you need a blood analysis by a certified laboratory. However, you can already tell roughly from some symptoms whether you have a vitamin D3 deficiency. These symptoms include:

  • Bone pain
  • Slow-healing bone fractures
  • Respiratory infections
  • Depression
  • Mood swings
  • Type 2 diabetes

These are just a few of the symptoms to be expected with vitamin D3 deficiency. However, to be on the safe side, a doctor should be consulted.

Studies have looked more closely at the link between diabetes and vitamin D3 and found that a consistently high vitamin D3 level can greatly reduce the risk of developing type 2 diabetes. So if you are prone to diabetes or belong to the risk group, you can reduce your risk by taking vitamin D3 supplements.

What is the shelf life of vitamin D3 drops?

Basically, the best-before date on the product always applies. This is only valid when unopened and should not be exceeded. Use beyond this date may result in undesirable side effects or even a complete lack of effect of the vitamin D3 drops.

The manufacturer is responsible for the safety and proper use of the product until the best-before date has been reached. Food supplements that consist of fat-soluble substances (such as vitamin D3) can easily become rancid and should therefore not be used beyond the expiry date. If you are nevertheless over the MDH, you can delay the consumption of vitamin D3 drops by up to two months by ideal storage.

What is the right dosage for vitamin D3 drops?

The optimal dosage has not yet been precisely determined by experts. An acceptable dose for children and adults over 65 years of age is 400 to 500 I.U. This means that higher dosages on a daily basis should be discussed with a doctor beforehand. The international unit I.E. was determined by the WHO and does not depend on the amount, but only on the effect of the food supplement.

What side effects can occur with vitamin D3 drops?

If you do not pay attention to the correct dosage and risk an overdose of vitamin D3 drops, you have to expect the following side effects:

  • Nausea
  • Lack of appetite
  • Headaches
  • Increased urination
  • Nervousness
  • Feeling of weakness
  • Kidney stones

For this reason, you should always consult your doctor before taking such high-dose drops and have a vitamin D3 deficiency determined. If such symptoms occur, stop taking the drops immediately and contact your doctor.

How much do vitamin D3 drops cost?

As a rule of thumb, high-dose drops tend to be more expensive than low-dose drops. Also, despite some additives, products for children tend to be in the low price segment. Here you can see a list by category and price range.

Dosage price range
Children's drops (800 I.U.) 5 to 10 euros
Drops for adults (1000 I.U.) 10 to 15 euros
High-dosage drops (up to 5000 I.U.) 15 to 25 euros

As you can see, the price differences are enormous. Before you buy, make sure you know which vitamin D3 drops you need and compare the prices of several suppliers on the internet to find the best product for you.

Where can I buy vitamin D3 drops?

You can get vitamin D3 drops in any pharmacy, of course, but also in most drugstores. In any case, it's worth taking a look at popular online platforms like Amazon. Here you have the largest selection of vitamin D3 drops.

The price in the pharmacy is always the most expensive, because here you have the option of getting advice from the pharmacist.

What types of vitamin D3 drops are there?

In the meantime, vitamin D3 drops are no longer only offered in pure form, but can also be of plant origin and without artificial additives. Here is a rough overview of what is available on the market:

Type Description
Vegan 100% plant-based active ingredient, mostly derived from lichen.
Suitable for children Easy dosage up to 500 I.U., dissolved in oil for better absorption.
High dose High dosage from 5,000 I.U., do not use daily without a doctor's advice
Vitamin mix Addition of vitamin K2 for bone maintenance and blood promotion.

There is a wide range of vitamin D3 drops. Your own taste plays a role here.

What alternatives are there to vitamin D3 drops?

If you don't like vitamin D3 in liquid form as drops, you have a wide choice of alternatives. The following alternatives are suitable for vitamin D3 food supplements:

  • Tablets
  • Capsules
  • Powder

These are the three most popular alternatives for vitamin D3 drops. They have a longer shelf life than drops and usually come in larger packs so you can stock up for months.

However, you can also eat foods that are rich in vitamin D3 in a completely natural way. These are, for example, fatty fish such as salmon or herring. 100 grams of herring contain 31 μg of vitamin D3 and salmon contains 16 μg. As you can see, you can also maintain your vitamin D3 levels naturally.
