Mozarin can be combined with Ashwagandha, but it is worth being careful. In some people, such a combination can intensify drowsiness, dizziness, or affect anxiety and well-being. If you experience this type of symptoms during supplementation, you should give up the supplement.

In the case of combining with Euthyrox, it is also worth being careful. There is scientific evidence that ashwagandha can affect thyroid function and increase hormone levels. In people taking levothyroxine, this may exacerbate symptoms of hyperactivity, such as palpitations, trembling hands or anxiety.
Therefore, the body's reaction should be observed.
