Introduction
Choosing the best dietary supplements plays a crucial role in our health and well-being. Current scientific studies provide new insights into the effects and importance of nutrients, vitamins, and minerals in our body and which supplements are sensible. In addition to a balanced diet and regular exercise, supplements such as vitamin D, magnesium, and zinc can support your health and have a positive effect on the body. It is especially important that the mineral is dosed correctly – whether standardized or high-dose. For selecting the right products, high quality with natural, plant-based ingredients as well as sustainability and scientifically based formulations are important. In this article, we inform you about the top-rated dietary supplements and provide an overview of the most important supplements and capsules as well as tips on intake and dosage.
Why are dietary supplements important?
Dietary supplements serve to complement the normal diet and are increasingly used by people to strengthen their own health and compensate for deficiencies. In a fast-paced world, a balanced and healthy lifestyle is often neglected by many. According to a nutrition study by Techniker Krankenkasse, more than half of respondents aged 18 to 59 lack the time for healthy eating. Other studies show that less than 50% of women and less than 30% of men consume fruits and vegetables daily. Instead, our diet contains too many carbohydrates and unsaturated fatty acids – the result is too few vitamins and nutrients for our body. Supplementation can specifically complement nutrient intake and improve physical well-being.
Dietary supplements for the immune system
Also as dietary supplements for the immune system and for disease prevention, these products are gaining increasing importance according to the latest scientific findings. Vitamins and minerals such as vitamin C and zinc help to strengthen the immune system, while calcium and vitamin D are recommended for osteoporosis. For people who frequently suffer from muscle cramps, magnesium can provide helpful support.
The most important supplements for vegans and vegetarians
For vegans and vegetarians, supplementation is also sensible because the avoidance of animal foods can hardly cover certain nutrients. Vitamin B12, for example, belongs to the microorganisms that are only sufficiently present in animal products and must be supplemented in a vegan diet. Since iodine deficiency can also often occur with this diet, supplementation with iodine is also recommended.
Dietary supplements in pregnancy
And those who are pregnant or breastfeeding should pay attention to suitable dietary supplements in pregnancy to ensure adequate supply of vitamins, trace elements, and nutrients and to promote the development of the baby. While folic acid significantly reduces the risk of malformations according to scientific studies, omega-3 fatty acids are essential for brain development, visual function, and the nervous system.
Benefits of dietary supplements based on scientific evidence
Vitamin D
The benefits and effects of dietary supplements are based on scientific findings: For example, the Federal Institute for Risk Assessment considers additional intake of vitamin D supplements in the winter months to be sensible, as many people do not spend enough time outdoors and sunlight exposure is significantly lower in the dark season than in summer. Vitamin D is especially important for the development and maintenance of bones and teeth and supports the function of the immune system. When the body does not produce enough vitamin D, a vitamin D deficiency occurs, which can cause symptoms such as fatigue and exhaustion as well as bone and muscle pain.
Magnesium
Magnesium is important for vital functions in the body such as regulating heart rhythm, blood pressure, as well as muscle contraction and a healthy nervous system. According to the DGE, magnesium deficiency can develop due to an unbalanced diet or as a result of intestinal magnesium absorption, which is often accompanied by symptoms such as muscle cramps, fatigue, tremors, and weakness. In these cases, supplementation with magnesium is recommended to regulate the mineral deficiency.
Omega-3 fatty acids
Omega-3 fatty acids are long-chain and polyunsaturated fatty acids that inhibit blood clotting, can lower blood pressure, and have a positive effect on the flow properties of the blood. Since Omega 3 cannot be produced by the body itself, it must be obtained through food or dietary supplements. According to studies, an adequate intake of Omega-3 fatty acids of 300 mg per day can reduce the risk of cardiovascular diseases.
Vitamins and Minerals: The Best Dietary Supplements of 2025
Due to increasing interest in targeted nutrient supply and a healthy, holistic lifestyle, more and more people rely on scientifically based dietary supplements that have a positive effect on the body.

How to choose the best dietary supplements?
With the wide range of supplements on the market, choosing the right best dietary supplements can be difficult. For effective efficacy and quality, you should consider some aspects before purchasing:
Supplements with certificates and third-party testing
Safe preparations should always be certified and sealed by recognized institutions and undergo testing by independent third parties to ensure high quality and safety. Strict quality controls ensure that the dietary supplement contains only the stated ingredients, is not harmful to health, and is effective.
High quality without harmful additives
Pay attention to high-quality supplements without harmful and chemical additives such as preservatives, artificial colorings, or fillers, which can potentially cause physical complaints. The best dietary supplement should contain natural and plant-based ingredients that are well tolerated - whether by pregnant women, nursing mothers, athletes, or older people. Choose manufacturers who demonstrate transparency in their ingredients and specify the sources precisely.
High bioavailability for better effect
Dietary supplement test winners with high bioavailability have a better effect because the body can absorb and utilize the nutrients better. If the product has low bioavailability, it cannot be fully absorbed and does not achieve the desired effect.
Reputable providers with regular checks
Only buy dietary supplements from reputable providers who regularly conduct quality checks on their products and clearly label the ingredients. Only tested and high-quality products offer you safety when taking supplements. Dietary supplements from trusted brands like Nutraceuticals für Haar offer safe and pure products that can be taken without concern.
Tips for effective intake of dietary supplements
The proper intake of dietary supplements is a crucial factor for effectiveness and body health. For the best results and to avoid side effects, you should follow some tips:
The right time to take supplements
For supplements to be effective in the body, they should be taken at the right time - and this varies depending on the nutrient. Since our body needs fat or oil to absorb Vitamin D, it is best to supplement it together with a meal. With zinc, it is exactly the opposite: since some foods like grains or legumes can inhibit its effectiveness, take zinc capsules best with a time gap from meals. Magnesium can be supplemented regardless of the time of day or meal - for cramps, taking it in the evening is recommended so that the magnesium concentration decreases less overnight.
Consider interactions with other medications
If you need to take medications in addition to dietary supplements, possible interactions should be considered. There are drugs and medications like antibiotics or blood thinners that can enhance or reduce the effect of supplements. Consult your doctor or pharmacist before purchasing a product.
Dosage is key
To achieve the desired effect with a dietary supplement, the correct dosage is crucial. According to the Federal Institute for Risk Assessment, more than two-thirds of people take supplements weekly. However, under- or overdosing can cause health damage: while too much Vitamin D raises calcium levels and can cause headaches, nausea, and even kidney damage, an excess of Vitamin B3 increases the risk of blood pressure drop and liver damage. To know how much dietary supplements you should take and over what period, a blood test must be done by a doctor beforehand. This can determine whether and how severe your deficiencies are and which supplements you need.
Conclusion: Dietary supplements in review
Choosing the best dietary supplements is essential for physical and mental health. With the right supplements, you can support your immune system, enhance your well-being, and prevent deficiencies. By targeted intake of Vitamin D, magnesium, omega-3 fatty acids, zinc, and other dietary supplements, nutritional needs can be met when a normal diet is no longer sufficient in everyday life. For safety and effectiveness, high-quality products should be used, scientifically based and subjected to strict quality controls. For optimal supplement effects, correct dosage, timing of intake, and interactions with medications are important. Rely on reputable brands like Nutraceuticals to obtain safe preparations with the best possible results. When it comes to the question "which dietary supplements make sense," it depends on individual needs. Whether pregnant women, athletes, or vegans: the right supplements are crucial for optimal health support.

FAQ
Can I take several dietary supplements at the same time?
Since dietary supplements are not medicines, it is generally possible to take several supplements at the same time. However, some minerals interfere with the effect of other substances, such as zinc and iron. In this case, you should take both dietary supplements at least two hours apart.
How do I recognize high-quality dietary supplements?
High-quality dietary supplements are characterized by high-quality ingredients such as natural and plant-based components and are free from harmful and artificial substances like fillers, colorants, flavorings, or preservatives. All ingredients should be transparently listed on the label and tested under strict guidelines. A trustworthy manufacturer also states the place of manufacture as well as the batch number and expiration date.
Are dietary supplements suitable for everyone?
The Federal Office of Consumer Protection and Food Safety advises careful use of dietary supplements and considers supplements useful for people with nutrient deficiencies. Those who eat a balanced and varied diet and have no deficiencies detected through a blood test do not need to take dietary supplements. For certain population groups such as pregnant women, athletes, vegetarians, and vegans, the nutrient requirement increases or cannot be covered through diet, so supplementation is recommended here. But even in these cases: first have a medical examination to get a recommendation for the right products and dosage.
