Some amateur sports enthusiasts take products such as vitamin tablets to avoid nutrient deficiencies without knowing whether they actually lack nutrients. And that is not advisable, according to the August edition of Ernährung im Fokus magazine.
Negative effects of food supplements on health and productivity cannot be ruled out, according to the report.
If there are fears of deficiencies, blood and urine tests as part of an annual or twice yearly check-up of one's nutritional status are more advisable than taking such products at random. If a nutrient deficiency is detected, it can be specially treated.
