Recent research has shown that the active ingredients in flaxseed, namely B vitamins, potassium, beta-carotene, iron, zinc and magnesium, can positively affect stress levels in the body. By providing a wide range of nutrients, flaxseed improves the metabolism and boost the immune system, two factors that can definitely impact stress. The nutrients present in flaxseed generate more neurotransmitters, including those for pleasure and satisfaction, countering the negative, anxiety-inducing effects of stress hormones.
