Hormones have a way of making themselves known. Some weeks bring a short fuse, disrupted sleep or a body that feels like it belongs to someone else, and for many women that rhythm shifts again, often unpredictably, in the years leading up to menopause. None of it means anything is wrong with you. It's simply your body moving through a natural cycle, and a lot of women are looking for gentle, natural ways to feel a little steadier through it.
Hemp seed oil has become part of that conversation. This guide looks at what's actually happening hormonally during PMS and perimenopause, where hemp seed oil's fatty acid profile fits into the picture, what the research does and doesn't yet say, and some gentle everyday rituals to try.
What's Happening Hormonally During PMS and Perimenopause
In the days before a period, levels of oestrogen and progesterone drop, and that shift is linked to the mood changes, fatigue, bloating, cravings and sleep disturbance that many women recognise as PMS.
Perimenopause is a longer, less predictable version of the same story. In the years before menopause, hormone levels rise and fall unevenly rather than following a steady monthly pattern. This transitional stage is commonly associated with mood changes, disrupted sleep, hot flushes and shifts in energy, and it can last anywhere from a couple of years to closer to a decade.
Both stages are a normal part of a woman's life, but that doesn't make them easy to live with, which is why so many women look for everyday, natural support alongside whatever else they have in place.
Where Omega Fatty Acids and GLA Fit In
Hemp seed oil is one of the few plant oils that naturally contains gamma linolenic acid (GLA), alongside its balanced spread of omega 3 and omega 6 fatty acids. GLA is a building block your body uses to produce certain prostaglandins, compounds involved in a wide range of processes, hormonal signalling among them.
This is why GLA rich oils, including evening primrose oil and hemp seed oil, have long been part of conversations around women's hormonal wellbeing. It's worth being clear about what this does and doesn't mean: it's a nutritional building block your body can draw on, not a hormone itself, and not a guaranteed fix. Think of it as giving your body good raw materials to work with, rather than a direct lever on your hormones.
What the Research Says
The research specifically on hemp seed oil and hormonal health is still young, but it's genuinely interesting.
A 2023 study tested hemp seed oil specifically in a rat model of perimenopausal depression. Rats were given hemp seed oil daily for four weeks, and researchers measured both depression-like behaviour and markers along the HPA axis, the system that governs your body's stress response and sits closely alongside hormonal regulation. The hemp seed oil group showed improvements on those measures compared to untreated rats.
The honest summary: this is one early, animal based study, not a settled clinical answer, and it can't tell us how hemp seed oil affects women actually going through perimenopause. It's reasonable to find that direction of research interesting without treating hemp seed oil as a proven treatment for PMS or perimenopause symptoms. It's a supportive, natural addition to consider, not a replacement for medical care.
Gentle Daily Rituals to Try
If you'd like to bring hemp seed oil into your routine as part of supporting yourself through these hormonal shifts, simplicity works best.
- A morning smoothie. Stir a teaspoon of Aussie Legend Premium Hemp Seed Oil into your usual breakfast smoothie, so it becomes an easy, unthinking part of your morning.
- Capsules with breakfast. If a liquid oil isn't for you, our Hemp Seed Oil Capsules, 1000mg, 60 pack, offer the same daily habit without any measuring or taste.
- Support during your PMS week. Our Provex Enhanced Relief Hemp Seed Oil is a terpene enhanced formulation, taken as drops, that some women prefer to reach for specifically in the lead up to their period.
- A wind down ritual for disrupted sleep. Perimenopause often brings restless nights, and our Provex Enhanced Sleep Hemp Seed Oil is formulated as part of an evening routine, taken shortly before bed.
A Nod to the Bigger Picture: Mind, Body and Soul
Hormonal wellbeing isn't only physical. Many of the women we hear from pair a daily hemp seed oil ritual with the wider holistic practices that already ground them, whether that's a few quiet minutes of journaling, herbal tea, gentle movement, or simply keeping a favourite crystal close by. Rose quartz, in particular, is one many women keep on a bedside table or in a pocket during emotionally heavier weeks, less as a fix and more as a small, grounding reminder to be gentle with yourself. If that's a practice you enjoy, our rose quartz collection is worth a browse.
None of this replaces medical care or a conversation with your doctor. It's simply about building a routine, however small, that supports the whole of you, not just the symptom in front of you on any given day.

Frequently Asked Questions
Can hemp seed oil balance my hormones? There's no evidence that hemp seed oil changes hormone levels directly. What it offers is GLA and a balanced spread of omega fatty acids, nutrients some early research suggests may support the body during hormonal shifts. It's a supportive addition to your routine, not a hormonal treatment.
Is hemp seed oil safe to use during perimenopause? Hemp seed oil is sold as a food in Australia and is generally well tolerated. As with any supplement, it's worth checking with your GP first, particularly if you're on medication or managing another health condition.
How long before I'd notice anything? Nutritional changes like this tend to work gradually as part of an overall diet and routine, rather than producing an immediate effect. Give it a few weeks of consistent use before drawing any conclusions.
Should I use the oil, capsules, or a Provex formulation? It comes down to preference and purpose. The plain oil and capsules suit a general daily routine, while the Provex Relief and Sleep formulations are designed for a more specific moment, PMS week or bedtime respectively.
Can I take this alongside my regular medication? Speak with your GP or pharmacist before combining any new supplement with existing medication, including hormonal treatments.
