Quick answer

For sport and muscles, magnesium and amino acids are central: magnesium contributes to normal muscle function and to normal energy-yielding metabolism, protein to the maintenance of muscle mass. Good products combine these building blocks with restful regeneration and thus sensibly complement your training.

Anyone who trains regularly places higher demands on their own body – from muscle work through energy metabolism to regeneration. With the goal of sport & muscles, it is therefore not only about the training itself, but also about the right nutrient supply. This guide explains which nutrients play recognised roles for muscles and performance and which Scheunengut products fit sensibly into an athletic routine.

An honest word in advance: progress in sport comes from training, nutrition and recovery – food supplementation is the fine-tuning, not the engine. The following recommendations therefore concentrate on nutrients with authorised EU health claims that accompany muscle function, energy metabolism and regeneration, and openly classify where a product starts sensibly and where the basic work remains in the foreground.

What matters for the goal of sport & muscles

A central nutrient for athletically active people is magnesium. Several authorised EU health claims are relevant here: Magnesium contributes to normal muscle function, Magnesium contributes to normal protein synthesis and Magnesium contributes to normal energy-yielding metabolism. In addition: Magnesium contributes to the reduction of tiredness and fatigue as well as Magnesium contributes to the normal functioning of the nervous system – an important aspect especially after intensive sessions.

Around muscle building, the protein supply is also decisive. Amino acids are the building blocks of the body's own proteins. For athletically active people, a sufficient protein intake through the diet is therefore the basis. In addition, the general connection applies: Protein contributes to a growth in muscle mass and Protein contributes to the maintenance of muscle mass. Amino acid preparations provide the necessary building blocks in concentrated form.

Regeneration and sleep also play a role for athletic progress, because the body recovers above all in rest periods. To support the night's rest, melatonin is occasionally used: Melatonin contributes to the reduction of time taken to fall asleep (the beneficial effect is obtained by consuming 1 mg shortly before bedtime). In this way the circle of training, nutrients and recovery closes.

Melatonin sleep complex 1mg per tablet with magnesium

Regeneration happens during sleep. This complex provides 1 mg of melatonin per tablet in combination with magnesium. For the night's rest it applies: Melatonin contributes to the reduction of time taken to fall asleep, and in addition Magnesium contributes to the normal functioning of the nervous system. A sensible building block if you take your recovery after training seriously. View melatonin sleep complex with magnesium

Foundations first

No supplement replaces good training, a needs-based diet and sufficient recovery. You lay the basis for muscles and performance with a structured training plan, enough high-quality protein through the diet, sufficient sleep and planned regeneration phases. If you eat a varied diet, you already cover many nutrients through food. Food supplements then come into play when the requirement rises through intensive training, when individual nutrients are difficult to cover through the diet, or when you want to supplement your routine in a targeted way. Pay attention to the recommended intake amount and make sure not to overdose the same nutrient through several products at the same time – with magnesium in particular it is worth looking at the overall intake.

Also think of recovery as part of training. Muscles do not grow and adapt during exertion, but in the hours and nights afterwards. Anyone who trains intensively but sleeps too little and supplies too little protein unnecessarily slows their own progress. Therefore plan fixed regeneration days, pay attention to a protein intake spread across the day and treat yourself to sufficient sleep. Fluid supply also plays a role, since the body loses water and electrolytes during training. A magnesium complex and a good amino acid supply fit into this overall picture but replace neither the structured training plan nor the consistent basic supply through the diet. In this way food supplementation remains the fine-tuning that sensibly rounds off an already solid routine.

How to find the right product

Start with your personal focus. If you pay attention above all to muscle function and regeneration, a high-quality magnesium complex is a solid entry point, because magnesium contributes to normal muscle function and to normal energy-yielding metabolism. If you place the focus on protein supply, you sensibly supplement with a complete amino acid complex, since amino acids are the building blocks of the body's own proteins.

In a second step, pay attention to dosage and bioavailability. With magnesium, the amount of elemental magnesium is decisive, not the pure total weight of the compound – a complex of several bioactive sources covers a broad spectrum here. With amino acids, it is worth looking at whether all essential amino acids are contained, since the body cannot produce these itself and must take them in through food.

Thirdly, think of recovery. Muscular adaptation does not happen during training, but in the breaks and during sleep. A set that bundles magnesium and amino acids covers the two central building blocks for active people in one step, while a product for the night's rest rounds off regeneration. In this way you put together a routine that thinks of training, nutrients and recovery together, instead of combining individual preparations indiscriminately.

Frequently Asked Questions (FAQ)

Why is magnesium so important for athletes?

Magnesium is involved in many processes in the body. Especially relevant for active people: magnesium contributes to normal muscle function and to normal energy-yielding metabolism and contributes to the reduction of tiredness and fatigue. This makes it a sensible building block around training.

Do amino acids do anything for muscle building?

Amino acids are the building blocks of the body's own proteins. Protein contributes to the maintenance of muscle mass and to a growth in muscle mass. A sufficient protein intake through the diet remains the basis; amino acid preparations provide the building blocks additionally in concentrated form.

When should I take magnesium?

The timing can be chosen flexibly; many active people take magnesium in the evening or around training. More important than the exact timing is an even intake across the day in line with the recommended intake amount. Observe the information on the packaging.

What does sleep have to do with muscles?

The body regenerates above all in rest periods and during sleep. A good night's rest thus indirectly supports your athletic goals. Melatonin contributes to the reduction of time taken to fall asleep when 1 mg is consumed shortly before bedtime.

Do supplements replace training?

No. Training, a needs-based diet and recovery are the foundation for progress. Food supplements are a supplement, not a substitute. They help to supply individual nutrients such as magnesium or amino acids in a targeted way.

Note: In the case of existing illnesses, during pregnancy and breastfeeding or when taking medication, please speak with your doctor before use.
