What are food supplements and what are they used for?

Food supplements are typically products in powder or tablet form that contain various combinations of vitamins, minerals, trace elements, plant extracts, or other health-promoting substances. As the name suggests, they are used to supplement daily nutrition—for example, when needs are increased or to prevent deficiencies.

Especially under high stress, with alternative diets (e.g., vegan or vegetarian), or in certain life stages (such as pregnancy or menopause), targeted intake of specific health-supporting substances can be sensible. Many athletes also regularly use supplements to naturally support recovery or physical performance.

Order health products online

Organic supermarkets, drugstores, pharmacies, and online shops offer a wide range of health products and supplements for every need. The most popular products most people reach for are the following:

• Multivitamins for daily baseline coverage and balancing deficiencies
• Vitamin D3 & K2 for strong bones and immune function
• Magnesium & zinc to support muscle function and immunity, especially in winter
• Omega-3 fatty acids for heart and brain health
• Herbal extracts such as ashwagandha or curcumin for stress reduction 

These minerals and vitamins come in various formulations and for different needs so they can match specific life situations. At The Tester, our assortment is regularly reviewed and expanded with new, proven health products. This way, you can always try new items and get the most out of your health. However, avoid combining multiple supplements without guidance, as interactions can occur between different vitamins and minerals.

What to look for when buying supplements

Not every supplement delivers on its promises. It’s therefore crucial to focus on quality, transparency, and safety. One of the most important indicators of a quality product is a clear ingredient declaration, listing every substance and explaining it in understandable terms. Hidden additives or vague umbrella terms should raise a red flag—trustworthy providers are transparent with customers.

Equally important is avoiding unnecessary fillers, artificial flavors, or colors that serve no health function and only affect appearance or texture. Reputable manufacturers prioritize pure actives and the most natural composition possible.

Another mark of quality is lab-tested composition, ideally examined regularly by independent laboratories. Analysis of the actual active-ingredient content also assures you’re truly getting what the label states.

Beyond quality and composition, dosage recommendations play an important role. Ensure they are communicated clearly and understandably—ideally tailored to age, sex, or special needs.

At The Tester, you’ll receive only vetted health products that meet the highest quality standards.
