At Best-Supps, you'll find vitamins as single supplements and practical combinations from selected brands – from Vitamin D3 to multivitamins, to Vitamin C and B vitamins, in tablets, capsules, or drops. Discover the range below. In the guide below that, we explain what vitamins are, who benefits from supplementation, and what to look out for when buying.
What are vitamins?
Vitamins are organic compounds that the body needs for numerous normal functions and – with a few exceptions – cannot produce itself. They must therefore be regularly consumed through food. Unlike carbohydrates, fats, and proteins, vitamins do not provide energy, but rather play a supportive role in metabolism as micronutrients.
In a balanced, varied diet, vitamins are abundant – especially in fruits, vegetables, whole grains, dairy products, fish, and meat. Food supplements with vitamins are useful when the intake through diet is insufficient in certain situations. As "vitamins", "vitamin supplements", or "vitamin nutritional supplements", they are among the most frequently purchased health products.
What types of vitamins are there?
A total of 13 vitamins are considered essential for life: the fat-soluble vitamins A, D, E, and K, and the water-soluble vitamins C and the eight B vitamins (including B1, B2, B6, B12, and folic acid). Each performs its own tasks in the body, and none can be completely replaced by another. This is precisely why a varied diet is the best foundation – it provides the full spectrum. Nutritional supplementation targets specific gaps that may exist in individual cases.
Fat-soluble and water-soluble vitamins
Two groups are distinguished. Fat-soluble vitamins like Vitamin A for normal vision and immune function, D, Vitamin E as protection of cells from oxidative stress, and Vitamin K for normal blood clotting and the maintenance of normal bones can be stored by the body; they are best absorbed with some fat. Because they are stored, it is particularly important to ensure an appropriate, not excessive, intake. Water-soluble vitamins (the B vitamins and Vitamin C), on the other hand, are hardly stored and are vital substances involved in many processes in the organism and metabolism – an excess is usually excreted, which is why regular intake is more important.
This classification also explains why some vitamins are offered as drops with oil (e.g., Vitamin D3) and others as tablets or effervescents (e.g., Vitamin C). You can find out which form is practical for you further down.
Do you need additional vitamins?
To be honest: If you eat a balanced and varied diet, you are usually well supplied with vitamins. A blanket extra intake "for everyone" is not necessary. However, there are situations in which many consciously supplement – for example, in the dark winter months, with a one-sided diet, in certain life stages, during stress or illness with an increased vitamin requirement, or with a purely plant-based diet (here, vitamin B12 is particularly relevant).
Whether and what makes sense for you can best be clarified individually – in case of doubt, through medical clarification, for example via blood values, or personal consultation. Nutritional supplementation does not replace a balanced diet, but it can specifically support vitamin supply when there is a gap or deficiency. That is precisely why we offer single vitamins and combinations.
What foods contain vitamins?
The best source of vitamins remains a varied diet. Here are some examples of where certain vitamins are naturally abundant:
Vitamin C
Abundant in citrus fruits, bell peppers, blackcurrants, berries, broccoli, and cabbage.
Vitamin D
In significant quantities, mainly in fatty fish; however, the body produces most of it itself with the help of sunlight. Vitamin D deficiency is common in Western latitudes.
B Vitamins
In whole grains, legumes, nuts, meat, fish, and eggs; vitamin B12 is found almost exclusively in animal products.
Fat-soluble vitamins A, E, K
In vegetables (such as carrots), vegetable oils, nuts, and green leafy vegetables. They are best absorbed with some fat.
An overview of the most important vitamins
Here you get a compact overview of the vitamins available from us – for details, each type leads to its own category page.
Vitamin D3
Vitamin D3 – the "sunshine vitamin" – can be produced by the body itself with the help of sunlight; however, in the winter months, self-production is low. Vitamin D contributes to the normal functioning of the immune system and the maintenance of normal bones. You can find the complete selection in the Vitamin D3 category.
Multivitamins
Multivitamins combine several vitamins – often supplemented with minerals and trace elements – in one product, thus covering a broad spectrum at once. They are the uncomplicated basis for anyone who doesn't want to combine several single supplements. Find out more in the Multivitamins category.
Vitamin B12 & B-Complex
B vitamins are a group of water-soluble vitamins; the vitamin B complex includes several B vitamins and serves, among other things, to support metabolism. Vitamin B12 is found mainly in animal foods and is therefore particularly relevant for purely plant-based diets. Additionally, vitamin B3 plays a role in protein metabolism for athletes. More in the Vitamin B12 & B-Complex category.
Vitamin C
Vitamin C is one of the most well-known water-soluble vitamins. Vitamin C contributes to the normal functioning of the immune system. You can find the selection in the Vitamin C category.
Overview of Vitamins
Vitamin | Type | Typical Situation | Common Form |
|---|---|---|---|
Vitamin D3 | Fat-soluble | Sunshine vitamin, winter months | Drops, capsules |
Multivitamins | Combination | Broad basic supply | Tablets, capsules |
Vitamin B12 & B-Complex | Water-soluble | Relevant for vegan diets | Tablets, drops |
Vitamin C | Water-soluble | Fruit & vegetable-rich diet | Tablet, powder, effervescent |
Vitamin K2 | Fat-soluble | Often combined with Vitamin D3 | Drops, capsules |
Vitamins in various life situations
Whether supplementation makes sense depends heavily on the individual situation. A few typical scenarios:
Little sun & winter months
During the darker months, the body produces significantly less Vitamin D because sunlight is needed for its synthesis. Many therefore specifically supplement Vitamin D3, especially in winter. Whether and how much is sensible can be clarified medically through a blood test.
Vegan & vegetarian diet
For a purely plant-based diet, Vitamin B12 is a particular concern, as it is found almost exclusively in animal foods. In this case, targeted supplementation is especially advisable.
Sports & active lifestyle
Athletes and people with an active lifestyle are usually well-supplied. Nevertheless, some use a multivitamin as a convenient base to broadly cover their nutrient needs depending on their training volume.
Elderly people & special phases
In certain life stages, for example during pregnancy, the need for or absorption of individual vitamins can be altered. In such cases, medical clarification is the most sensible approach, rather than supplementing indiscriminately, which is particularly important for pregnant women.
Vitamins and Minerals
In addition to vitamins, minerals are important micronutrients. Unlike vitamins, minerals are inorganic – these include magnesium, zinc, calcium, or iron. Many multivitamins combine both groups in one product. If you want to specifically supplement a mineral, you can find the selection in the Minerals category. Vitamins and minerals complement each other well, but together they do not replace a balanced diet and also play a role in the utilization of certain minerals and other nutrients in the body.
Dosage Forms
Vitamins come in many forms: Tablets and capsules are precisely dosed and practical, drops (common for Vitamin D3) and drinking ampoules as a liquid can be precisely dosed and taken directly or diluted with water, and effervescent or direct variants (common for Vitamin C and B vitamins) are pleasant to take and also suitable for children or people who dislike swallowing; gummy bears or lozenges are also child-friendly options. Which form is right depends primarily on personal preference; you can sort specifically using the filters in the shop.
How are vitamins absorbed in the body?
Absorption depends on the type of vitamin. Fat-soluble vitamins (A, D, E, K) are better absorbed with dietary fats – therefore, taking them with a meal containing some fat is advisable. Water-soluble vitamins (B vitamins, Vitamin C), on the other hand, are absorbed easily and can be taken throughout the day.
The form also plays a role: oil-based drops are well suited for fat-soluble vitamins like D3, while water-soluble vitamins are often offered as effervescent tablets or regular tablets. These differences explain why different vitamins are commonly available in different dosage forms. For concrete intake, always observe the information on the packaging.
Buying Vitamins – what should you look for?
Single vitamin or combination
Do you want to specifically supplement a single vitamin (e.g., Vitamin D3 in winter) or cover a broad spectrum at once (multivitamin)? This determines the product choice.
Dosage & transparent declaration
Look for a clear indication of the vitamin content per serving. Especially with fat-soluble vitamins, an appropriate, not excessive, dosage is important.
Dosage form
Tablet, capsule, drops or effervescent – choose according to your daily routine and preference.
Brand & quality
Reputable manufacturers stand for transparent information and consistent quality. At Best-Supps, we carry vitamins from selected brands.
Intake & important notes
The serving size and time of intake are stated on the respective product packaging – follow the manufacturer's instructions and do not exceed the recommended amount. A vitamin deficiency can manifest in the organism through fatigue and organic complaints, among other things. Fat-soluble vitamins (A, D, E, K) are best taken with a fat-containing meal and should not be highly dosed uncontrollably due to their storage capacity. In case of existing diseases, during pregnancy and breastfeeding, or if unsure, medical advice is advisable before taking them. Food supplements are not a substitute for a balanced diet.
Common misconceptions about vitamins
Several misunderstandings persist about vitamins. Here are three briefly clarified:
"More is better"
More is not automatically better. Fat-soluble vitamins, in particular, are stored, which means an excessive intake is not advisable. The crucial factor is a needs-based amount, not the highest dose.
"You only need vitamins in winter"
The body needs vitamins all year round. Only for vitamin D does the season play a special role, as its self-production depends on sunlight.
"Supplements replace a healthy diet"
They do not. Fruits, vegetables, and whole foods provide far more than just individual vitamins. Nutritional supplements specifically close gaps, but they do not replace a balanced diet.
Related Categories & Useful Supplements
Vitamins complement other micronutrients well. It's worth looking into the categories Minerals (e.g., magnesium) and Omega-3 & healthy fats. Further products for your well-being can be found under Health. If you also want to meet your protein needs, you'll find what you're looking for under Proteins.
Quality, Storage & Shelf Life
You can recognize a high-quality vitamin supplement by a transparent, complete declaration and a clear dosage statement. Established brands stand for consistent quality.
For storage: Tablets, capsules, and drops should be stored dry, sealed, protected from heat and light – and out of reach of children. The best-before date and all instructions can be found on the respective packaging.
Frequently Asked Questions about Vitamins (FAQ)
Vitamins are micronutrients that the body needs for numerous normal functions and mostly cannot produce itself. They are taken in through food.
With a balanced diet, the supply is usually good. Supplementation makes sense in certain situations – for example in winter (vitamin D) or on a purely plant-based diet (vitamin B12). When in doubt, clarify with a doctor.
Fat-soluble vitamins (A, D, E, K) can be stored by the body and are best absorbed with some fat; water-soluble ones (B vitamins, vitamin C) are barely stored and should be taken in regularly.
A single vitamin is suitable if you want to specifically close a gap; a multivitamin covers a broad spectrum easily all at once.
All forms are possible. Tablets and capsules are precisely dosed, drops can be finely dosed, effervescent tablets are pleasant to take. The choice is a matter of taste.
Especially with fat-soluble vitamins, an excessive intake is not sensible, as the body stores them. Stick to the dosage instructions on the packaging and, when in doubt, clarify with a doctor.
That depends on the vitamin: fat-soluble vitamins (A, D, E, K) are best taken with a fat-containing meal, water-soluble ones can be spread across the day. The exact timing is stated on the packaging.
Chemically, many vitamins are identical, whether from a natural or synthetic source. What matters is the actual composition and a balanced diet – „natural“ alone is not proof of quality.
In principle yes, but make sure not to take the same vitamins in high doses multiple times (for example multivitamin plus single supplements). When in doubt, check the total amounts or clarify with a doctor.
No. Besides vitamins, fruit and vegetables provide many other valuable ingredients. Dietary supplements close specific gaps but do not replace a balanced diet.
Most reliably through a medical evaluation, for example via blood values. Self-diagnosis is not advisable – targeted supplementation is more sensible than a blanket approach.
Not automatically. What matters is the actual composition and a transparent declaration, not the price or the label.
In principle yes. Just make sure not to take the same nutrients (for example from a multivitamin and a booster) in high doses multiple times. When in doubt, check the total amounts.
Since vitamin D is fat-soluble, it is better absorbed together with some dietary fat. Taking it with a meal is therefore sensible. Details are stated on the packaging.
Not fundamentally – both provide the vitamin. Drops can be finely dosed and are well suited to fat-soluble vitamins like D3, tablets are precisely portioned. The choice is a matter of taste.
