We all know serotonin as the happy hormone in the brain, but not many know how it can effect us as far as our physiques are concerned.
Low levels of serotonin can result in the following symptoms:
– craving fatty foods, especially fried, and stodgy carbs such as chips, crisps and potatoes
– feeling anxious and/or worried
– lack of motivation
– struggling to get out of bed once awake
– pain sensitivity
After looking at the symptoms, it is easy to understand how serotonin deficiency can effect your lifestyle in a way that will thwart your performance on more levels than just the gym alone.
Fixing the problem is down to nutrition (as always lol). There is an amino acid called l-tryptophan that is responsible for synthesising serotonin. Food sources are highly unreliable nowadays, so supplements are definitely your best option. Go with 1g of pure tryptophan before bed and the problems should cease. If you chose to go with food sources, good luck, and be sure to eat plenty of red meat, fish, poultry, sunflower seeds, almonds, pumpkin seeds, dried dates, and spirulina.
