Helps balance hormones for women of all ages

Hormone Harmony helps target and correct hormonal imbalances— including Estrogen, Progesterone, Testosterone and Prolactin levels. The specific blend of ingredients is shown to work for women at different stages of their lives as it adapts to their unique problems.

Combats nutrient deficiencies in women

Hormone Harmony PLUS helps eliminate common Antioxidant, Mineral and Vitamin deficiencies in women of all ages and further improve overall health, energy, and well-being. It’s also designed to boost the absorption of Hormone Harmony by up to 115%

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.

Pomegranate Fruit Extract acts as a natural multivitamin in its own right containing high levels of Vitamins A, B6, B12, C, E, K along with magnesium and potassium. It also contains 3x more antioxidants than green tea.

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).

Myo-Inositol is shown to increase “happy” hormones, serotonin and dopamine. It could also regulate blood pressure, metabolic syndromes, and the hormone imbalances that cause PCOS.

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.

The MCTs in Hormone Harmony PLUS can boost absorption in the digestive system by 115%. When both Hormone Harmony formulas are taken together, all ingredients can be absorbed better and provide faster results. MCTs are also shown to cause increased feelings of fullness which reduces food intake and limits sugar cravings—this alone makes it easier to stick to a diet and maintain healthy weight.



Collagen has been shown in clinical studies to make skin smoother, hair thicker and nails stronger. It also helps joints, bones, and muscles maintain structure. Another great benefit is that it repairs the gut lining for optimal digestive health. Also, collagen is the most filling protein, increasing feelings of satiety by up to 36%. That means it can be used as a delicious “snack” or as a healthy way to reduce hunger.

How does the formula taste?

Hormone Harmony doesn't taste like anything because the ultra potent capsules are contained within 4 tiny plant-based capsules. The Hormone Harmony PLUS has a subtle flavour of pomegranate (thanks to the Pomegranate Fruit Extract). It’s perfect for a morning drink: not too sweet, but just tasty enough to start the day on the right foot.

Prebiotic Collagen Protein has a natural vanilla bean flavour that has been praised by hundreds of Happy Mammoth customers. It’s not overpowering, but it gives any drink that unmistakable taste of homemade desserts.

Every formula in The Complete Hormone Synergy System is produced in small batches to maintain ultra high-quality levels in a TGA, HACCP and International Standards 9001 Certified facility in sunny Queensland, Australia and Sydney, Australia.
