Managing PMS with PCOS: Exploring Natural Alternatives

Managing PMS with PCOS: exploring natural alternatives

Managing a turbo cocktail of hormones is enough to deal with when you have PCOS. But the added burden of PMS can make you feel like your emotions are even more heightened: you might be feeling tearful, a little more agitated or particularly low. Sadly, there’s no magic potion to zap away PMS, but thankfully there are steps you can take to make it a hell of a lot easier. One route is natural supplementation. Whilst they won’t all work for you, they can be a great tool to combat PMS and PCOS together.

Mighty magnesium

Although little heralded, magnesium may be one of the most important health-promoting minerals. As well as restoring some harmony to your insulin secretion, magnesium works as brilliant pain reliever for PMS. In one study, a supplementation of 250mg was given to a group of female participants aged 18-45 over a 3-month period. The results were pretty amazing, indicating that magnesium helped diminish many of the physical symptoms caused by PMS like cravings, insomnia and bloatingi. Another study illuminated the positive impact magnesium had on the emotional implications of PMS too, such as alleviating mild anxiety and reducing fatigueii.

You can obtain magnesium from a range of foods including spinach, Swiss chard, dark chocolate, cashews, almonds and Brazil nuts. However, to properly safeguard against a deficiency and bolster the body’s natural reserves, we would advise adding a high-strength, quality magnesium supplement to the diet – provided, of course, it contains an easily absorbed form of the mineral.

Vital vitamin B6

Vitamin B6 is involved in the production of serotonin – your ‘feel-good’ hormone that supports mood and fills you with that get-up-and-go sensation. A controlled trial highlighted that taking 50-100mg of vitamin B6 each day significantly reduced the depressive symptoms triggered by PMSiii. 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. However, if you struggle to meet your requirements through food alone, we suggest taking 100mg per day in supplement form. Learn more about the benefits of vitamin B6 and PCOS here.

Think zinc

Renowned for its far-reaching and promising health properties, zinc plays a key role in regulating your menstrual cycle.  Interestingly, levels of zinc are considerably lower in PMS patients compared to healthy groups of womeniv. In fact, studies have shown that supplementing zinc in the last 2 weeks of your menstrual cycle can be very beneficial for PMS4. Just 50mg of taking zinc daily can contribute to a marked decrease in PMS symptoms – namely anxiety and depression, and there was a significant improvement in their quality of life too.
Taking 15mg (30mg on doctor's advice) of zinc for 2 weeks before your period may help keep pesky PMS symptoms at bay. Red meat, oysters, shellfish, pumpkin seeds, and cashews are all excellent, natural sources of zinc.

Magic myo-inositol

In the days leading up to your period, does your ravenous alter ego make an appearance, tempting (and successfully convincing) you to eat your bodyweight in ice cream, chocolate, pizza, crisps, pasta, bread, sweets - whatever takes your fancy. Cravings are a natural part of PMS – that’s nothing new. One explanation for this is that the changes in your hormone levels require more calories. Research now suggests that myo-inositol holds the power to stabilise insulin levels, thereby curbing your cravingsv. Even better news: myo-inositol is also thought to reduce acne and anxiety, which are additional PMS annoyancesvi.

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

Go crazy for calcium

Research indicates that calcium levels tend to be lower in those experiencing PMS, which may contribute to headaches, depression, sleep issues, appetite changes, and joint painvii. But one study highlighted that supplementing with 100mg to 120mg could decrease these debilitating and painful symptoms. It’s also worth noting that low levels of magnesium are associated with poor calcium levels, so it’s wise to up your intake of both minerals to supercharge your natural reserves.

You may think that scoffing your face with milk and yoghurt is the answer here. Sadly, 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, exacerbating your other PCOS symptoms – it’s a double-edged sword, really. You can meet your calcium requirements by filling up on spinach, leafy greens, salmon and cheese. Or, to ensure you meet the 100mg mark, you can take a high-strength, quality calcium supplement.

Final thoughts…

PMS can be totally and utterly debilitating, period. And while most women will experience their fair share of moods swings, headaches and stomach cramps, PCOS can make this monthly affair even more problematic and painful. Unfortunately, there are no quick fixes.  But by upping your intake of the nutrients we’ve mentioned above, you should be able to manage the symptoms and live a happy and fulfilling life.
