Serotonin is a powerful neurotransmitter required for the brain and body to feel happy, it is often labelled the ‘happy hormone’. Up to 90% of serotonin is found in the gut. It is no wonder that with the poor habits of the Western diet we see so many stagnate gut conditions such as candida, leaky gut and dysbiosis. With the over-proliferation of negative gut flora, there is a decline in the storage and production of the essential hormone for happiness, Seratonin. The specific functions of the neurotransmitter Seratonin are:
Oestrogen and progesterone receptors are also found in serotonin-producing receptors in the brain. Oestrogen increases the production rate and receptor density of serotonin, as well as that of endorphins and other beneficial neurotransmitters. Declining oestrogen during peri-menopause seems to lead to lower levels of serotonergic activity, which might contribute to the depression and mood changes which are common during this phase.
