Induces a full night’s sleep naturally

Deep Sleep Mode helps women get 7+ hours of deep, rejuvenating sleep 100% naturally. Deep Sleep Mode not only helps women fall asleep faster, but it also helps maintain a deep state of calm and relaxation all through the night - without feeling groggy in the morning.

Reduces signs of aging inside and out

Collagen is known for making skin smoother and nails stronger. It also helps joints, bones, and muscles maintain structure. The Prebiotics in the formula can help with weight loss by turning dietary intake into energy instead of promoting storage in the form of fat.

Science-Backed Benefits of the Complete Hormone Synergy System

The adaptogenic ingredients in Hormone Harmony were carefully selected to target and adapt to unique hormone imbalances, so the formula can help women of all ages with different types of hormonal health problems.

Deep Sleep Mode helps reactivate parts of the brain that may have been “dulled” by poor quality sleep. Once cognitive function is improved, the brain starts making new connections, reflexes are heightened, and energy levels are increased together with concentration power.

Collagen has been shown in clinical studies to make skin smoother, hair thicker and nails stronger. It also helps joints, bones, muscles and the gut lining maintain structure. It also stops sugar cravings when consumed as a healthy snack.

The synergistic ingredients in Deep Sleep Mode naturally release Melatonin, GABA and Serotonin at precision-timed intervals. This helps achieve a happy, peaceful and profoundly rejuvenating sleep—even during stressful times or in a noisy environment.

Ashwagandha has been shown in scientific studies to eliminate stress up to 44%, while the Rhodiola extract is proven to reduce anxiety and depression symptoms, inducing a greater sense of calm and happiness.

Prebiotics can help with weight loss by turning dietary intake into energy instead of promoting storage in the form of fat. They also help power good bacteria while crowding out the bad ones, reducing symptoms associated with yeast overgrowth.

Deep Sleep Mode contains a potent natural ingredient that’s been shown to help the body fall asleep faster by inducing a sense of calm and preventing churning thoughts, anxiety or a restless body from taking over control.

Gelatinised Maca has been shown to eliminate hot flashes, night sweats and random body temperature changes by at least 74% (up to 87% in some cases).
