Managing PMS with PCOS: Exploring Natural Alternatives

Managing PMS with PCOS: exploring natural alternatives

Managing a cocktail of hormones can feel like enough to deal with when you have PCOS. But the added burden of PMS can make your emotions even more pronounced. Sadly, there’s no magic bullet to completely alleviate PMS. However, you can support the reduction of symptoms with the correct approach – in particular, using supplementation. Here, we outline the best natural aids for managing PMS with PCOS. 

Natural supplements for PMS

Premenstrual syndrome (PMS) encapsulates the symptoms many women experience in the weeks before their periodi. Almost every woman will have PMS at some point in their lifetime. PMS can manifest both emotionally and physicallyii.  

Emotional and behavioural symptoms:

  • Mood swings 

  • Anxiety 

  • Fatigue 

  • Depression 

  • Irritability, aggression or anger 

  • Clumsiness 

  • Difficulty sleeping 

  • Forgetfulness 

  • Reduced self-confidence 

Physical symptoms 

  • Tender breasts 

  • Feeling bloated 

  • Headaches 

  • Food cravings 

  • Constipation or diarrhoea 

  • Backache 

  • Hot flushes or cold sweats 

  • General ache and pains 

  • Acne 



Though little-heralded, magnesium may be one of the most important health-promoting minerals. As well as supporting insulin sensitivity – a common characteristic of PCOS – magnesium may soothe PMS-related stomach cramps. 

In one study, 250mg of magnesium was given to a group of female participants aged 18-45 over a 3-month period. The findings revealed magnesium helped to diminish many of the physical symptoms caused by PMS, like cravings, insomnia and bloatingiii

You can obtain magnesium from a range of foods including spinach, Swiss chard, dark chocolate, cashews, almonds and Brazil nuts. To properly safeguard against a deficiency and bolster the body’s natural reserves, however, we recommend adding a high-strength, easily absorbed, quality magnesium supplement to your diet.

Vitamin B6

As you may know, PMS can lead to mood disturbances, including anxiety, low mood, and irritability. Crucially, vitamin B6 is involved in the production of serotonin, the body’s ‘feel-good’ hormone, which supports mood and floods the brain with joy, positivity and overall wellbeing. 

A controlled trial highlighted taking 50-100mg of vitamin B6 each day may reduce depressive symptoms triggered by PMSv. This study further concluded that women who supplemented their vitamin B6 intake with magnesium reported a greater reduction in their emotional PMS symptoms than simply taking magnesium alone. 

Rich food sources of vitamin B6 include organic meat, potatoes, starchy vegetables, non-citrus fruits and chickpeas. If you struggle to meet your requirements through food alone, we suggest taking 100mg per day in supplement form.

Think zinc

Zinc also plays a key role in regulating your menstrual cycle.  Some experts believe taking zinc daily may decrease anxiety, depression – often symptomatic of PMS – and improve the overall quality of life, too. 

Interestingly, levels of zinc are noticeably lower in women exhibiting PMS symptoms than those who don’t.  Studies have shown that supplementing zinc in the latter 2 weeks of your menstrual cycle could be enormously beneficial for PMSvi.

We recommend taking 15mg of zinc daily to help ease PMS symptoms. While red meat, oysters, shellfish, pumpkin seeds, and cashews are all excellent, natural sources of zinc, a quality supplement is a great insurance policy. 


Food cravings are a natural part of PMS. One explanation for this is the changes in your hormone levels require more calories. Research now suggests myo-inositol may stabilise insulin levels, thereby controlling your cravingsvii.

Besides this, myo-inositol is also purported to reduce anxiety, which is often characteristic of PMSviii. Indeed, inositol supports the production of serotonin in the brain – an important ‘feel-good’ neurotransmitter that impacts mood and behaviour.  Research suggests it may help to reduce the number of panic attacks in those with panic disordersix.

The most prevalent sources of myo-inositol are unprocessed whole grains, citrus fruits, dried prunes and brewer’s yeast. However, you would have to eat huge quantities to get your daily dose. The simpler and more convenient option is to take 2 to 4 grams of myo-inositol in powdered form each day.


Research indicates that calcium levels tend to be lower in those experiencing PMS, which may contribute to headaches, low mood, sleep issues, appetite changes, and joint painx. But one study highlighted that supplementing with 100mg to 120mg may support the reduction of these symptomsxi.

It’s also worth noting that low levels of magnesium are associated with poor calcium levels. That’s why it’s essential to increase your intake of both minerals to reinforce your natural reserves. Learn more about the benefits of calcium for PCOS women here

You may think boosting your milk and yoghurt intake is the solution here. But it’s not the case. These foods have a high glycaemic index (the rate at which your body breaks down carbs for energy) and will cause a spike in your insulin and androgen levels, potentially exacerbating other PCOS symptoms, like weight gain and acne. 

You can meet your calcium requirements by adding more leafy greens, salmon, tofu and nuts to your diet. To ensure you meet the Nutrient Reference Value (NRV) of 100mg, we recommend taking a high-strength, quality calcium supplement.

Final thoughts…

For many women, PMS can be hugely debilitating. And while most will experience their fair share of moods swings, headaches and stomach cramps, PCOS can make this monthly affair even more challenging and painful. Unfortunately, there are no quick fixes.  But by increasing your consumption of the nutrients outlined above, you can certainly help to manage some of the symptoms.
