Period mood swings: serotonin keeps the balance


A week or two before menstruation, commonly known as a period, mood swings, low energy, sleep changes and other symptoms are experienced by over 90% of women around the world[1]. Most women can function normally since their symptoms are mild. For 20-40% of these women, these symptoms can interfere with daily lives and are referred to as PMS – a premenstrual syndrome. The good news is that nutrition offers a ray of hope to help you feel better during PMS. An easy way to produce more happy brain chemicals like serotonin is by using supplements like 5-htp.

What hormone deficiency causes PMS?

A decrease in the sex hormone oestrogen causes your feel-good chemical to go low. Your hormones fluctuate during your menstrual cycle. 7 to 10 days before your period, there is a decrease in sex hormones like oestrogen. This is the phase when most women experience PMS symptoms[2]. Changes in hormones also affect serotonin levels. This feel-good chemical regulates your mood and sleep. If this brain chemical is low, this explains some of the PMS symptoms like period mood swings. Understanding how your body changes during the menstrual cycle can make it easy to find efficient premenstrual syndrome treatments. Serotonin’s building block, tryptophan, is found in protein-rich foods like meat or soy products. Oestrogen increases the production of the chemical that converts tryptophan to serotonin[3]. It also helps serotonin to be available for longer to perform its function. In simple terms: 

More oestrogen = more serotonin = happier you

How can I balance my hormones week before my period? 

Supplements for PMS are one way to balance your hormones. One of the most popular ones is serotonin’s building block 5-htp. Why? Well, PMS can get serious for some women who develop a disorder known as PMDD. If you’re interested in the topic you can read more about PMS vs PMDD. PMDD therapy is currently focused on antidepressants that prolong serotonin availability in the brain[4]. Antidepressants, however, have serious side effects for many people. That’s why researchers were looking into 5-htp & PMS to see if that would help women dealing with PMS symptoms safely increase their serotonin levels. Since serotonin has a major impact on mood, behaviour and PMS symptoms like irritability, serotonin-boosting supplements could ensure increased sociability and agreeableness for women at all times[6]. Let’s take a look at a supplement that can help you raise serotonin - PMS’ natural helper called 5-htp. 

Which supplement is best for PMS?

5-htp is the shortcut to serotonin. When tryptophan is consumed, a small amount enters the brain where it is first converted to 5-htp and then to serotonin. Directly taking 5-htp bypasses the need for oestrogen to facilitate the conversion. brain feed’s 100 mg of 5-htp can help you easily and safely increase serotonin levels whenever you feel the need.

5-htp has been evidenced to benefit those with depressive symptoms. A review of 7 studies showed that 60% of those taking 5-htp reported full treatment of depressive symptoms[7]. This means, 5-htp can simplify the equation: 

More serotonin = happier you

What is the best thing to take for PMS mood swings?

While a lot of minerals and vitamins can help ease PMS symptoms, 5-htp is an efficient natural way to directly increase your serotonin levels which are low during PMS. With 5-htp, you can feel happier and sleep better which can help with PMS symptoms as well. Opting for a diet full of protein-rich foods can also help ease your menstrual journey. 

How can I increase my serotonin before my period?

A quick way to increase your serotonin levels is via your diet. Some of the best foods for PMS mood swings are :


Food sources (per 100g) and their nutrient content

Vitamin B6

A review of 12 studies recommended supplementing vitamin B6 to help with PMS symptoms due to its involvement in production of brain chemicals[8].

Women need 1.2mg Vitamin B6 per day.

  • roasted pistachios (1mg)
  • tuna (1mg)
  • lima beans (1mg)
  • sunflower seeds (1mg)


It the building block of serotonin and found in protein rich foods

  • tofu (750mg)
  • chia seeds (720mg)
  • pork (630mg)
  • mozzarella cheese (600mg)


Zinc is involved in maintaining hormonal balance and improving mood. Its levels drop during PMS levels and supplementation has shown to relieve symptoms[9].

Non-pregnant/lactating women need 7mg zinc per day.

  • beef (10mg)
  • sesame seeds (8mg)
  • dried mushrooms (8mg)
  • roasted peanuts (7mg)


Oestrogen is involved in calcium regulation in the body. Low calcium levels are seen in those with PMS. Calcium is involved in production of serotonin. Reviews have shown benefit of increased calcium intake in lowering PMS symptoms[10].

Non-pregnant/lactating women need 700mg calcium per day.

  • tofu (prepared with calcium sulphate) (2134mg)
  • roasted almonds (291mg)
  • parmesan cheese (1376mg)
  • Milk, skim (204mg)
