- Evening primrose oil (GLA) has demonstrated anti-inflammatory and hormone-modulating effects relevant to menstrual cycle discomfort.
- Magnesium deficiency is strongly linked to PMS; supplementation has been shown to reduce water retention, mood changes, and anxiety associated with the luteal phase.
- The formula targets multiple hormonal pathways simultaneously, making it a comprehensive option compared to single-ingredient alternatives.
What is NOURISH PLUS?
NOURISH PLUS is a women's hormonal balance supplement specifically formulated to address the complex interplay of hormones that govern the menstrual cycle, mood, sleep, and overall well-being. Developed with a multi-ingredient approach, the formula centres on three cornerstone ingredients: Evening Primrose Oil, Vitex Agnus-Castus, and Magnesium — each with documented clinical research supporting their role in hormonal health.
Unlike many women's supplements that rely on a single botanical or nutrient, NOURISH PLUS is designed around the principle that hormonal imbalance is multifactorial. The luteal phase of the menstrual cycle is governed by the balance between oestrogen and progesterone, and disruptions to this balance can trigger a cascade of symptoms — from mood instability and irritability to physical complaints such as bloating, breast tenderness, and sleep disruption.
NOURISH PLUS targets these mechanisms from several angles: vitex works on the pituitary-hypothalamic axis to support progesterone levels relative to oestrogen; evening primrose oil provides gamma-linolenic acid (GLA), an omega-6 fatty acid that modulates prostaglandin synthesis and inflammatory pathways involved in cramps and breast pain; and magnesium supports neurotransmitter function, smooth muscle relaxation, and the activity of enzymes essential to steroid hormone metabolism.
The result is a supplement designed not just for PMS symptom relief, but for foundational hormonal support across the entire cycle — making it relevant for women experiencing irregular periods, perimenopausal hormonal shifts, PCOS-related hormonal disruption, or the generalised hormonal fluctuations that affect mood, energy, and cognition throughout adult life.

Research-Backed Benefits
Below we examine each key benefit of NOURISH PLUS in the context of the clinical and mechanistic evidence available for its primary ingredients. References are drawn from peer-reviewed literature indexed in PubMed.
1. Hormonal Balance Support via Vitex Agnus-Castus
Vitex agnus-castus (chaste tree berry) is the most extensively researched botanical for female hormonal regulation. Its primary mechanism of action involves binding to dopamine D2 receptors in the anterior pituitary gland, which suppresses prolactin secretion. Elevated prolactin — a condition known as hyperprolactinaemia — is associated with luteal phase deficiency, irregular cycles, and a range of PMS symptoms. By normalising prolactin, vitex indirectly supports the relative balance of progesterone to oestrogen in the luteal phase.
A landmark placebo-controlled trial by Schellenberg (2001) recruited 178 women with premenstrual syndrome and randomised them to receive either a standardised vitex extract (Ze 440) or placebo over three menstrual cycles. The vitex group demonstrated significantly greater improvements across the primary outcome measure — a composite of five PMS symptoms — compared to placebo, with 52% of the vitex group reporting treatment success versus 24% in the placebo arm. The authors concluded that vitex was a well-tolerated and effective treatment for PMS.
A subsequent systematic review by Dante & Facchinetti (2011), published in the Archives of Gynecology and Obstetrics, evaluated nine randomised controlled trials of herbal treatments for PMS and concluded that vitex agnus-castus was the most consistently effective botanical, with evidence supporting reductions in irritability, mood changes, anger, headache, and breast fullness. The review noted an acceptable safety profile with adverse events comparable to placebo in most trials.
2. PMS Symptom Relief: Evening Primrose Oil and GLA
Evening primrose oil (EPO) is extracted from the seeds of Oenothera biennis and is notable for its high content of gamma-linolenic acid (GLA), an omega-6 fatty acid that is a precursor to prostaglandin E1 (PGE1). PGE1 has anti-inflammatory, vasodilatory, and platelet-aggregation-inhibiting properties. Women with PMS and cyclic mastalgia (breast pain) have been found to have altered fatty acid profiles, with lower levels of GLA and its downstream metabolites, suggesting a deficit in this pathway.
Research has specifically implicated GLA deficiency in the development of cyclic breast pain. A study by Pruthi et al. (2010), published in the Breast Journal, evaluated the role of fatty acid supplementation in mastalgia and found that evening primrose oil supplementation was associated with significant improvements in breast pain severity over a treatment period of several months, with its most pronounced effect in women with severe cyclic pain. The authors noted that EPO's mechanism likely involves correction of the abnormal fatty acid ratio observed in affected tissue.
Beyond mastalgia, GLA's influence on prostaglandin metabolism has implications for dysmenorrhoea (painful periods). Excessive production of pro-inflammatory prostaglandins (particularly PGF2α and PGE2) in the endometrium during menstruation is the primary driver of uterine cramping. By shifting the prostaglandin balance towards the less inflammatory PGE1 pathway, GLA supplementation via evening primrose oil may help reduce the severity of menstrual cramps and the systemic inflammation that amplifies PMS symptoms.
3. Mood Stabilisation and Anxiety Reduction with Magnesium
Magnesium is one of the most abundant minerals in the human body and serves as a cofactor in over 300 enzymatic reactions, including those governing neurotransmitter synthesis and release. Its role in mood regulation is mediated partly through its action as a natural antagonist to the N-methyl-D-aspartate (NMDA) glutamate receptor — a mechanism shared with certain antidepressants and anxiolytics. Low magnesium status has been consistently associated with heightened anxiety, irritability, and depressive symptoms, all hallmark features of PMS.
A pivotal study by Facchinetti et al. (1991) demonstrated that women with PMS had significantly lower red blood cell magnesium concentrations compared to non-PMS controls, providing biological plausibility for magnesium supplementation as a therapeutic strategy. When supplementation was administered (360 mg/day from day 15 of the cycle through to the onset of menstruation), participants experienced significant reductions in mood-related symptoms compared to placebo, with the authors concluding that magnesium supplementation is effective in alleviating premenstrual mood changes.
A later randomised trial by Walker et al. (1998) extended these findings, showing that a combination of magnesium and vitamin B6 produced greater reductions in premenstrual anxiety, nervous tension, and mood swings than either supplement alone, suggesting synergistic activity. Magnesium also plays a direct role in regulating the hypothalamic-pituitary-adrenal (HPA) axis, and deficiency is associated with exaggerated cortisol responses to stress — a factor that can significantly amplify hormonal imbalance during the luteal phase.
4. Reduced Bloating and Fluid Retention
Bloating and fluid retention are among the most commonly reported and debilitating physical symptoms of PMS, affecting an estimated 50–92% of women who experience the condition. The mechanisms are multifactorial, involving aldosterone-mediated sodium and water retention, altered gastrointestinal motility driven by hormonal fluctuations, and increased gut sensitivity during the luteal phase. Magnesium's role in reducing PMS-related bloating is particularly well evidenced.
The Walker et al. (1998) study referenced above specifically examined fluid retention as a primary outcome. Women receiving 200 mg elemental magnesium per day showed significant reductions in weight gain, swelling of extremities, breast tenderness, and abdominal bloating compared to the placebo group, with benefits becoming more pronounced with the second month of treatment. The mechanism is believed to involve magnesium's ability to antagonise aldosterone and modulate prostaglandin-mediated changes in vascular tone and permeability.
Vitex agnus-castus contributes to this benefit through its suppression of prolactin. Prolactin has well-characterised effects on fluid balance, including direct actions on the kidney tubule promoting sodium retention. By attenuating the hyperprolactinaemia that characterises the luteal phase in many women with PMS, vitex may indirectly reduce the hormonal drive towards fluid accumulation. Evening primrose oil further modulates prostaglandin balance, which influences local tissue oedema and inflammatory water retention in breast tissue and the lower abdomen.
5. Better Sleep Quality During the Luteal Phase
Sleep disturbance is a frequently overlooked symptom of hormonal imbalance, yet studies indicate that up to 70% of women experience measurable changes in sleep architecture across the menstrual cycle, with the most significant disruptions occurring during the late luteal phase. These changes include reduced slow-wave sleep, increased sleep latency, more frequent nocturnal awakenings, and a heightened perception of fatigue upon waking — all of which are compounded by concomitant mood symptoms and physical discomfort.
Magnesium is one of the most evidence-supported nutrients for sleep quality improvement. A double-blind, placebo-controlled trial by Abbasi et al. (2012), published in the Journal of Research in Medical Sciences, randomised 46 elderly adults to receive either 500 mg magnesium or placebo for eight weeks. The magnesium group showed significant improvements in sleep time, sleep efficiency, sleep onset latency, early morning awakening, insomnia objective score, and serum renin and melatonin concentrations. The authors attributed the benefits to magnesium's role in regulating the circadian clock and its inhibitory effect on the NMDA receptor, which promotes relaxation of the nervous system.
Vitex agnus-castus may also contribute to improved sleep via its effects on melatonin release. Preclinical studies have identified melatonin receptor binding activity in vitex extracts, and some clinical observations suggest improved sleep quality as a secondary benefit of vitex therapy in women treated for PMS. Additionally, by reducing the anxiety, breast pain, and abdominal discomfort that interrupt sleep during the premenstrual period, the combined formula addresses the behavioural and physiological barriers to restful sleep simultaneously.
Who Should Consider NOURISH PLUS?
NOURISH PLUS is formulated primarily for adult women seeking evidence-based support for hormonal health. However, the spectrum of women who may benefit extends well beyond those with diagnosed PMS. Consider NOURISH PLUS if you identify with any of the following profiles:
- Women with moderate-to-severe PMS: If you regularly experience significant physical or psychological symptoms in the one to two weeks before your period — including mood swings, irritability, breast tenderness, bloating, or cramps — NOURISH PLUS provides multi-mechanism support targeting the root hormonal causes of these symptoms.
- Women with irregular menstrual cycles: Vitex agnus-castus has demonstrated cycle-regulating effects in women with oligomenorrhoea (infrequent periods) and luteal phase deficiency, particularly in cases where prolactin excess or suboptimal progesterone production underlies the irregularity.
- Women approaching perimenopause (ages 35–50): The hormonal fluctuations of perimenopause — characterised by declining progesterone, erratic oestrogen, and increasingly irregular cycles — share many features with PMS. NOURISH PLUS ingredients have relevance for this transitional phase, helping to manage mood instability, sleep disruption, and physical discomfort during the years leading up to menopause.
- Women with suspected magnesium deficiency: Dietary surveys consistently show that a significant proportion of women in developed countries do not meet recommended daily intake for magnesium. Sub-optimal magnesium status is associated with heightened PMS severity, anxiety, muscle cramps, sleep problems, and fatigue — all correctable with appropriate supplementation.
- Women seeking a non-pharmaceutical approach: NOURISH PLUS offers a botanical and nutritional alternative for women who prefer not to use hormonal contraceptives or psychoactive medications for PMS management, or who wish to complement existing medical treatment under the guidance of a healthcare provider.
- Women with PCOS: While NOURISH PLUS is not specifically formulated as a PCOS treatment, vitex has been investigated in the context of PCOS-related hormonal dysregulation, and magnesium has shown benefits in managing insulin sensitivity and inflammatory markers relevant to this condition.
Dosage & Safety
Understanding how to use NOURISH PLUS correctly — and being aware of relevant safety considerations — is essential for optimising its benefits and avoiding adverse interactions. The following guidance is based on clinical research and standard supplement practice. Always consult your healthcare provider before beginning any new supplement regimen, particularly if you have an existing medical condition or are taking medication.
Recommended Usage
| Ingredient | Clinically Studied Dose | Timing Guidance |
|---|---|---|
| Vitex Agnus-Castus (standardised extract) | 20–40 mg (standardised extract) or 400–500 mg (dried herb equivalent) | Once daily in the morning; consistent daily use for â¥3 menstrual cycles for full effect |
| Evening Primrose Oil | 1,000–3,000 mg per day (providing ~80–240 mg GLA) | With meals to enhance absorption; can be taken across the full cycle |
| Magnesium (glycinate, citrate, or malate forms) | 200–400 mg elemental magnesium per day | Can be split into two doses; evening dose may support sleep quality |
Onset of Action and Duration
It is important to set realistic expectations around the timeline for results. Unlike pharmaceutical drugs, which may produce rapid symptomatic relief, NOURISH PLUS works by addressing underlying hormonal imbalances — a process that takes time. Clinical trials of vitex typically report meaningful improvements after two to three menstrual cycles (2–3 months) of consistent use. Magnesium benefits may be experienced more quickly, with some women noticing improvements in sleep and anxiety within two to four weeks of supplementation. Evening primrose oil effects on cyclic breast pain and inflammatory markers typically require four to eight weeks to become apparent.
For this reason, NOURISH PLUS is best viewed as a long-term hormonal support strategy rather than an acute symptom reliever. Women who discontinue supplementation after only one cycle are unlikely to have experienced the full benefit of the formula, particularly the vitex component.
⚠️ Safety Considerations & Contraindications
- Pregnancy and breastfeeding: Vitex agnus-castus is not recommended during pregnancy. If you are pregnant, planning to conceive, or breastfeeding, consult your healthcare provider before use.
- Hormonal medications: Vitex may interact with hormonal contraceptives (e.g., oral contraceptive pills) and hormone replacement therapy (HRT). Discuss potential interactions with your prescribing physician.
- Dopamine-related medications: Due to vitex's dopaminergic activity, it may theoretically interact with dopamine agonists or antagonists (e.g., antipsychotic medications, Parkinson's disease drugs). Medical review is recommended.
- Bleeding disorders or blood thinners: Evening primrose oil has mild anti-platelet effects. Use with caution if you take warfarin, aspirin, or other anticoagulant/antiplatelet medications.
- Kidney disease: Women with impaired kidney function should consult a doctor before taking magnesium supplements, as the kidney is the primary route of magnesium excretion.
- Gastrointestinal effects: Magnesium at higher doses may cause loose stools or diarrhoea in some individuals; starting with a lower dose and titrating upward can minimise this effect.
- Allergy: Women with known allergies to plants in the Verbenaceae family or to evening primrose should check ingredients carefully before use.
