Low moods and stress go hand in hand. According to studies, they tend to coexist on an equal footing. As one's mood deteriorates, so does one's stress level, and vice versa. According to studies, taking ashwagandha for just two months can help to balance moods, improve sadness symptoms, and is a great brain supplement. Ashwagandha supports more even moods and improved mental clarity by acting as a cortisol manager.
