DuPont launches new probiotic to reduce stress DuPont Nutrition & Biosciences has launched HOWARU Calm, a probiotic aimed at helping dietary supplement manufacturers decrease the cycle of consumer stress. Surveys suggest 65% of adults worldwide indicate stress is a regular part of their daily lives. Prolonged stress can negatively affect mood, sleep and digestive health. HOWARU Calm is the most recent addition to DuPont’s HOWARU portfolio and is shown to manage the psychological response to perceived stress. “Too much stress, or daily chronic stress has become more prevalent in today’s society and can seriously impact our mental and physical well-being and overall health,” said Dr Elaine Patterson, senior R&D scientist, DuPont Nutrition & Biosciences.
