In a progesterone deficiency, we produce too much cortisol, and excessive cortisol causes osteoporosis, aging of the skin, damage to brain cells, and the accumulation of fat, especially on the back and abdomen.
- Progesterone has been shown to activate GABA receptors, which can potentially lead to a reduction in anxiety and excitation (4).
- Progesterone is well documented to support dopamine levels, and thus may support mood and motivation (5).
- Progesterone can antagonise the negative effects of excess estrogen, thereby contributing to a reduction in estrogen-dominance (6).
- Progesterone is able to reduce cortisol levels, since it is a glucocorticoid receptor antagonist (1).
- Progesterone decreases gut permeability (Leaky gut) through upregulating occludin expression in primary human gut tissues (2).
- Progesterone is a steroid hormone that is essential for the regulation of reproductive function (3).

Progesterone is a calming, yet adaptogenic hormone that can support one during times of stress.
I personally have not used this product yet. It's on my list to try in the future. It has a lot of potential for enhancing libido in both men and women. It's great to see Progesterone powder available in Australia.
