How to Identify Quality Dietary Supplements
These days, dietary supplements are available everywhere: in supermarkets, online, and even at discount stores. They are becoming increasingly popular, with trendy lifestyle brands often introducing innovative variations. Since all these products contain the 'same' vitamins, it can be tempting to choose a popular brand, the cheapest option, or the most attractive packaging. However, while all products promise the same benefits, there are significant differences in quality. The quality of cheap supplements can sometimes be so low that the nutrients are immediately lost in the body, providing no beneficial effect at all. What a waste!

Bioavailability
It all comes down to the absorbability of supplements, or bioavailability. This determines how quickly your body can process the supplement so that the beneficial properties of the active substances are realised. Therefore, we have outlined a few key points to consider when purchasing supplements. This will help you make an informed decision to support your health.
Opt for the Active Form of Vitamins
Certain vitamins, such as folic acid, vitamin B12, and vitamin D2, must be converted by your body into their active form before they can be absorbed. This conversion occurs with the help of your intestines and liver and requires energy. By directly supplementing vitamins in their active form, conversion problems can be avoided, resulting in higher bioavailability, better absorption by body cells, and less strain on the liver.
Pay Attention to the Compounds
There are inorganic and organic mineral compounds. The main difference lies in the substance to which the mineral is bound. Inorganic substances come from the earth's crust. These compounds are often used in supplements because they can be produced at lower costs. However, these compounds are much less absorbable by the body. Organically bound minerals naturally occur in our bodies and can therefore be absorbed much better, allowing them to work more effectively.
Natural vs Synthetic Vitamins
Whether you choose a natural or synthetic vitamin is particularly important if the efficacy of the natural and synthetic forms differs significantly. A good example of this is vitamin E. The natural form of vitamin E (d-alpha-tocopherol) is much more potent than its synthetic form (Dl-alpha-tocopherol).
Opt for Natural Excipients and Fillers Where Possible
In the production of supplements, especially tablets, it is sometimes necessary to use excipients and fillers. Otherwise, they simply cannot be properly dosed or manufactured. Quality supplements contain, where possible, only natural variants such as rice, peas, or alfalfa.
Synergy
Quality supplements can be recognised by specific combinations of nutrients within the same supplement. Some nutrients work synergistically with each other, meaning they enhance each other's effects or are required for absorption by the body. Magnesium and vitamin B6, for example, are a good pair, as are vitamin D3 and K2.
