In recent years, research has increasingly turned to natural substances that have the potential to have a positive impact on our health. One such substance that has gained attention is nattokinase. Originally derived from natto, a traditional Japanese food created by fermenting soybeans with the bacterium Bacillus subtilis, nattokinase has gained popularity due to its unique properties and potential health benefits. One of the research areas that has attracted interest in recent years is the effect of nattokinase on the thyroid. This article examines the properties of nattokinase, its potential effects on thyroid function, and the scientific evidence on the subject.
What is Nattokinase?
Nattokinase is an enzyme extracted from natto. It has fibrinolytic properties, meaning it can help dissolve fibrin, a protein that plays a role in blood clotting. Because of this property, nattokinase is often associated with improving blood circulation and preventing cardiovascular disease. In addition to these effects, there is also debate about the possible effects of nattokinase on other aspects of human health, including thyroid function.
The thyroid and its importance
The thyroid is a small, butterfly-shaped organ in the front of the neck that plays a central role in the endocrine system. It produces hormones that regulate the body's metabolism, growth and development. Thyroid dysfunction can lead to various health problems, including hypothyroidism (underactive thyroid), hyperthyroidism (overactive thyroid), and thyroid nodules.
Potential effects of nattokinase on the thyroid
Research into the effects of nattokinase on the thyroid is still in its early stages. Some studies suggest that nattokinase may have an indirect positive effect on thyroid function through its ability to improve blood circulation and reduce inflammation. Good blood circulation is essential for optimal thyroid function as it supports the distribution of thyroid hormones throughout the body.
Scientific evidence
To date, there are only a few direct studies examining the effects of nattokinase on thyroid function. Some preliminary studies in animal models and in vitro (in a test tube) have shown that nattokinase has anti-inflammatory properties and can improve blood circulation, which could theoretically support thyroid function. However, extensive human clinical studies are needed to confirm these potential effects and to understand exactly how nattokinase acts on the thyroid.
Safety and dosage
Although nattokinase is generally considered safe when consumed in the amounts obtained through food, caution should be exercised when used in supplement form. In particular, people who take blood thinners or suffer from blood clotting disorders should consult their doctor before taking nattokinase. There are still no consistent guidelines regarding the optimal dosage of nattokinase for specific health conditions, including those affecting the thyroid. Dosages in studies vary, and therefore it is important to follow the manufacturer's instructions and seek medical advice when taking nattokinase supplements.
Possible side effects and interactions
Nattokinase side effects are usually rare and mild, but can include stomach upset, nausea, and skin rashes. Due to their blood-thinning effects, there is a potential risk of bleeding, especially when combined with other blood-thinning medications such as warfarin or aspirin. It is also important to consider the potential interaction of nattokinase with medications that affect blood clotting and with medications that affect the thyroid, as this could increase or decrease the effects of these medications.
Summary and Outlook
Nattokinase is a promising enzyme with potential health benefits, including possible support for thyroid function. Despite the positive signs, scientific evidence regarding the direct effects of nattokinase on the thyroid is still limited. Future research, particularly well-designed human clinical trials, is critical to clarify the safety, efficacy, and mechanism of nattokinase's action on the thyroid.
The potential health benefits of nattokinase, including its effects on the thyroid, make it an interesting subject for future scientific study. However, it is important to exercise caution and seek professional medical advice when using nattokinase as a dietary supplement, especially in those with existing health conditions or those already taking medication. Balancing the promising health benefits and safety is essential to fully exploit the potential benefits of nattokinase without incurring unwanted risks
