Do children need more selenium than adults relative to body weight? 👧

Yes, when calculated per kilogram of body weight, children often require higher amounts of many micronutrients, including selenium, than adults. This is linked to periods of rapid growth and development.

Selenium plays an important role in:
• immune system function,
• protection against oxidative stress,
• thyroid hormone metabolism,
• nervous system development.

Although total daily selenium requirements are lower in children than in adults, their bodies need relatively higher intake per body weight.

This is why a balanced diet rich in natural micronutrient sources is particularly important during childhood-especially in regions of Europe where selenium availability in soil is lower.

How can stress and lack of sleep affect the body’s micronutrient needs? 😴⚡

Chronic stress and sleep deprivation affect not only wellbeing, but also how the body functions on a metabolic level.

During periods of stress, the body may use more nutrients involved in nervous system regulation, immune support and protection against oxidative stress. This includes micronutrients such as:

• selenium,
• magnesium,
• zinc,
• iron.

Insufficient recovery may also influence:

• hormone balance,
• inflammatory processes,
• appetite and food choices,
• nutrient utilisation efficiency.

Stress does not automatically cause deficiencies, but long-term overload may increase the importance of a balanced diet and regular meals.

This is why metabolic health depends not only on what we eat, but also on sleep, recovery and everyday lifestyle habits 🌱

Does the body “signal” nutrient deficiencies? 🤔

Fatigue, poor concentration, weaker immunity or changes in skin and hair condition are often interpreted as signs of vitamin or micronutrient deficiencies. But can the body really communicate deficiencies this way?

Partly yes, but many of these symptoms are highly non-specific. This means they may have multiple causes and do not necessarily indicate a deficiency of a particular nutrient.

For example:
• chronic fatigue may be linked to iron deficiency, but also to stress or lack of sleep,
• weaker immunity can be influenced by both diet and lifestyle,
• changes in hair or skin condition are not always caused by micronutrient deficiencies.

A common myth is that the body “craves” specific foods when it lacks certain nutrients. In reality, cravings are more often related to habits, emotions or energy balance than to precise biological signalling.

This is why laboratory testing and professional assessment remain the most reliable ways to identify nutritional deficiencies.

The body may send signals, but interpreting them requires a broader perspective 🌱
