Tinnitus is a complex phenomenon. Its causes and influencing factors can vary greatly, and the scientific approaches being investigated in this context are correspondingly diverse.
Micronutrients have also been the subject of research for years. Zinc, in particular, is frequently examined in this regard.
However, it is important to distinguish between two questions:
What role does zinc generally play in the human body?
and
Can zinc treat or improve tinnitus?
There are clear answers to the first question. Regarding the second, the study situation is much more cautious.
Zinc: an essential trace element with important functions
Zinc is involved in numerous physiological processes.
Among other things, zinc contributes
-
to normal cognitive function,
-
to the normal function of the immune system and
-
to the protection of cells from oxidative stress.
These functions are scientifically recognized and approved as health claims.
Precisely for this reason, zinc is also studied in many areas of research where cellular metabolism, oxidative processes, or neuronal functions play a role.
What does zinc have to do with tinnitus?
In scientific studies, the question has been repeatedly raised as to whether zinc status might be significant in people with tinnitus. Both observational studies and controlled trials involving zinc supplementation exist. However, the results are not consistent.
Individual studies have reported changes in tinnitus symptoms in specific participant groups, while other studies could not determine any relevant difference compared to a placebo.
Systematic reviews therefore also do not yet conclude that zinc can be considered an effective treatment for tinnitus.
From the current state of research, it cannot be concluded that zinc treats or improves tinnitus.
Nevertheless, research remains interesting, especially regarding the question of whether individual zinc status could play a role in certain groups of people.
Nutritional supply is different from therapy
Regardless of tinnitus research, the human body requires zinc for numerous normal functions. An adequate supply of zinc is therefore part of a balanced nutrient intake. Insufficient intake can occur, for example, with a very restrictive diet or certain forms of nutrition.
However, this does not mean that additional zinc intake would be generally necessary or effective for tinnitus.
Folate: a second important micronutrient
Folate belongs to the B-vitamin group and also fulfills several fundamental functions.
Folate contributes
-
to normal psychological function,
-
to the reduction of tiredness and fatigue,
-
to normal homocysteine metabolism,
-
to normal blood formation and
-
to cell division
processes.
These properties make folate an important component of general micronutrient supply.
Why zinc and folate can be combined
Zinc and folate fulfill different physiological tasks.
While zinc contributes, among other things, to normal cognitive function and the protection of cells from oxidative stress, folate supports, among other things, normal psychological function and contributes to the reduction of tiredness and fatigue.
A combination of both nutrients can therefore be useful if the diet is to be specifically supplemented with these micronutrients.
Whether additional supplementation is individually necessary, however, depends on factors such as diet, requirements, and nutritional status.
What does this mean for people with tinnitus?
Tinnitus should not be reduced to a single nutrient.
Research into zinc is scientifically interesting, but to date, it provides no confirmed evidence of a therapeutic effect on tinnitus. Regardless, an adequate supply of micronutrients remains part of a normal diet. Anyone suffering from persistent or newly occurring tinnitus should have possible causes medically clarified.
Conclusion
Zinc and folate are essential micronutrients with clearly defined physiological functions.
Zinc contributes to normal cognitive function, normal immune system function, and the protection of cells from oxidative stress.
Folate contributes to normal psychological function, the reduction of tiredness and fatigue, and normal homocysteine metabolism.
Furthermore, zinc has been scientifically studied in connection with tinnitus for years. However, the current data is not sufficient to derive a recommendation for the treatment or improvement of tinnitus.
It is precisely this distinction between scientific research and authorized health claims that is crucial.
