In short
Premenstrual syndrome encompasses a range of physical and emotional symptoms that occur in the luteal phase, the 1–2 weeks before menstruation, and resolve with the onset of the period. At CLCC, care for PMS follows a five-step structured assessment: Assess, Identify, Reduce, Restore, Continue, addressing the systemic contributors alongside standard medical treatment, rather than symptom management alone.
About This Condition
PMS is not inevitable, it is the hormonal cascade expressing through a nutritionally and metabolically depleted system.
Premenstrual syndrome encompasses a range of physical and emotional symptoms that occur in the luteal phase, the 1–2 weeks before menstruation, and resolve with the onset of the period. Symptoms range from mild irritability and bloating to severe mood disruption, breast pain, and cognitive impairment (PMDD, premenstrual dysphoric disorder). PMS is frequently normalised as an inevitable part of the female cycle. It is not. Its severity reflects the hormonal, nutritional, and metabolic environment in which the cycle is operating.
The luteal phase hormonal shift, rising progesterone, declining oestrogen towards the period, is the trigger. Whether this trigger produces significant symptoms depends on: magnesium status (deficiency worsens luteal phase mood and cramping); B6 status (essential for serotonin synthesis, which falls in the luteal phase); blood sugar stability (dysregulation amplifies luteal phase mood instability); gut oestrogen metabolism (poor clearance allows oestrogen recirculation worsening symptoms); and the progesterone-oestrogen ratio (relative oestrogen excess, or oestrogen dominance, produces the bloating, breast tenderness, and mood changes of PMS). CLCC addresses all of these specifically.
Symptoms
Common symptoms and presentations.
Mood changes, irritability, anxiety, tearfulness, or low mood in the 1–2 weeks before the period
Bloating and water retention in the days before menstruation
Breast tenderness or swelling
Headaches or migraine clustering premenstrually
Food cravings, particularly for carbohydrates and sugar
Fatigue and reduced energy in the week before the period
Difficulty concentrating and cognitive slowness
Sleep disruption in the luteal phase
Cramping pain in the lower abdomen and back
Symptoms that resolve within 1–2 days of the period starting
Contributing Factors
What drives and sustains this condition.
Magnesium deficiency
Magnesium regulates progesterone synthesis, reduces prostaglandin-mediated cramping, and supports serotonin production in the luteal phase. Deficiency, common in PMS, directly worsens mood, cramping, and headache severity.
Vitamin B6 deficiency
B6 is the cofactor for serotonin and dopamine synthesis. Luteal phase oestrogen changes already reduce serotonin, B6 deficiency compounds this, producing the characteristic mood instability of PMS. B6 supplementation is clinically effective for PMS mood symptoms.
Blood sugar instability
The luteal phase is a period of naturally elevated progesterone that affects insulin sensitivity. Blood sugar dysregulation in this context produces amplified mood instability, cravings, and fatigue. Dietary blood sugar stabilisation is a primary PMS intervention.
Gut oestrogen recirculation
The gut enzyme beta-glucuronidase, elevated in dysbiosis, deconjugates oestrogen metabolites, allowing them to be reabsorbed rather than excreted. This oestrogen recirculation worsens oestrogen dominance and amplifies PMS symptoms.
The CLCC Method: All Five Steps
Assessment first. Then all five steps, applied specifically.
Assess hormonal pattern, nutritional status, gut health, and blood sugar regulation
Luteal phase progesterone and oestrogen reviewed in cycle context. Magnesium, B6, vitamin D, and zinc assessed. Gut microbiome indicators and beta-glucuronidase activity evaluated. Blood sugar and insulin pattern assessed. Symptom severity and cycle pattern documented at baseline.
Identify dominant contributors, nutritional, oestrogen dominance, gut, or blood sugar
Nutritional-dominant PMS responds rapidly to magnesium and B6 correction. Oestrogen-dominant PMS requires gut restoration and dietary phytoestrogen and fibre correction. Blood sugar-driven mood instability requires dietary stabilisation as the primary intervention.
Targeted nutritional correction alongside dietary and gut protocol
Therapeutic magnesium glycinate, particularly in the second half of the cycle. B6 at evidence-based doses. Gut restoration to reduce oestrogen recirculation. Blood sugar stabilisation through meal timing and composition. Evening primrose oil where prostaglandin balance is indicated.
Track symptom severity across 2–3 cycles at minimum
PMS symptoms are cycle-specific, improvement is tracked across menstrual cycles, not weeks. A symptom diary reviewed at monthly consultations documents the trajectory. Protocol refined as nutritional status and gut health improve.
Sustain hormonal balance through ongoing nutritional and dietary maintenance
PMS returns when nutritional deficiencies reaccumulate or gut health deteriorates. The Continue phase provides nutritional monitoring, gut health support, and cycle-specific guidance, maintaining the hormonal environment that produces a symptom-free luteal phase.
FAQs
Common questions about care.
Is PMS the same as PMDD?+
PMS and PMDD exist on a spectrum of premenstrual symptom severity. PMDD (premenstrual dysphoric disorder) involves more severe mood disruption, significant depression, anxiety, or anger that impairs function. The physiological contributors are similar, with PMDD often involving more significant serotonin sensitivity and neurobiological vulnerability in the luteal phase. CLCC addresses PMS and mild-moderate PMDD through the same systemic framework.
Should I track my cycle during the programme?+
Yes, a symptom diary tracking symptom type, severity, and cycle day is an essential clinical tool for PMS management. It documents the baseline, tracks improvement, and helps identify specific nutritional or dietary triggers that are cycle-phase specific.
