Micronutrient knowledge
Micronutrient knowledge
Physiological functions, notes on high or insufficient intake and relevant interactions — presented separately from the specific product assessment.
Selenium
Selenium is an essential trace element. Product dosage, selenium form, reference values and total intake are considered separately in the assessment.
Functions
Selenium is a component of various selenoproteins and plays a role, among other things, in antioxidant defence systems, the regulation of thyroid-hormone metabolism and normal immune-system function.
Possible signs of insufficient intake
Insufficient selenium intake can impair various selenium-dependent enzyme systems. Symptoms are nonspecific; for an individual assessment, diet, supplemental intake and, where appropriate, laboratory parameters should be considered together.
Points to consider at high intake
Chronically high selenium intake can lead to selenosis. Reported signs include changes in hair and nails, a metallic taste, garlic-like breath, as well as gastrointestinal and neurological symptoms.
Special considerations
Baseline selenium status is particularly relevant when interpreting selenium studies. High additional intake is not automatically beneficial when selenium status is already adequate.
Interactions / caution
With high-dose long-term use, total intake from food and supplements should be taken into account. Individual medical conditions and drug therapies may require a separate assessment.
Scientific assessment
Studies, meta-analyses and randomized controlled trials on the active ingredient – explained clearly and linked to sources.
