Menopause vs Perimenopause: What's the difference and what are the nutritional needs?

Perimenopause: a gradual hormonal transition

The perimenopause refers to the transitional period that begins with the first hormonal signs and continues until one year after the last period. Its duration varies considerably from woman to woman. Averaging around 4 years, it can range from a few months to 8–10 years.

This significant variability is explained by the hormonal mechanism at work: as menopause approaches, the ovarian follicle reserve declines rapidly, making ovulation more irregular and hormonal production far less predictable. Ovulations are often incomplete or absent, with shortened luteal phases, resulting in lower and more erratic progesterone secretion, while oestrogen levels may still be elevated and, above all, highly fluctuating[1][2].

This phase generally begins between the ages of 40 and 50, sometimes even earlier. During this time, your body is still producing hormones, but in an irregular and fluctuating way. It is this instability that causes sometimes confusing symptoms: cycles that are sometimes short, sometimes long; periods that are heavy one month and absent the next; mood changes; and so on.

Menopause: a precise point in time

From a medical standpoint, menopause is defined as 12 consecutive months without a period, in the absence of any other identified cause. Biologically, it is typically characterised by persistently elevated FSH levels alongside low oestradiol levels, reflecting the exhaustion of ovarian function[3].

In France, the average age of menopause is around 51[4]. The fundamental difference from perimenopause is that menopause is not a phase, but a precise point in time — the moment when ovarian hormone production stops permanently. Menopause can therefore only be diagnosed retrospectively, after a full year without periods has been confirmed. It marks a definitive transition into a new stage of life.

Why do nutritional needs differ?

During perimenopause, intense hormonal fluctuations create particular nutritional needs. For example, premenstrual syndrome (PMS) can intensify considerably during this period, requiring tailored nutritional support. 

Periods can become very heavy or prolonged, increasing the risk of iron deficiency. Finally, this period prepares the body for the menopause: it is the ideal time to strengthen bone and metabolic health before the definitive hormonal decline.​

B vitamins (B6, B9, B12)

B vitamins play a central role in hormonal regulation, as well as in reducing anxiety and depression linked to hormonal fluctuations. They support energy production and the healthy functioning of the nervous system, which is particularly under strain during this transition.

Several clinical trials and meta-analyses show that vitamin B6 may help reduce the emotional symptoms of premenstrual syndrome (depression, irritability, fatigue)[5]. As PMS tends to worsen during perimenopause, an adequate intake of vitamin B6 may therefore be particularly beneficial during this period.

Magnesium

Several clinical trials show that magnesium may help reduce the symptoms of premenstrual syndrome, particularly anxiety, irritability, and mood fluctuations. This nutrient also contributes to the regulation of mood and stress through its action on various neurotransmitters (serotonin, GABA). It has also been associated with improved sleep quality in several studies on hormonal disorders and perimenopause[6][7].

Calcium and vitamin D

Perimenopause is a strategic time to pay attention to your bone health, as bone density loss generally begins to accelerate around the menopausal transition[8]. Calcium and vitamin D play a key role together in maintaining bone mineralisation and are among the fundamentals of osteoporosis prevention in midlife women[9].

Given that the drop in oestrogen after the menopause accelerates bone loss, it is advisable to check, from perimenopause onwards, that your calcium and vitamin D intake is sufficient (through diet and, if needed, supplements) in order to best protect your bone density in the long term.

Iron

During perimenopause, periods can sometimes be very heavy or prolonged, which increases the risk of iron loss and iron deficiency. An iron deficiency, especially if it progresses to anaemia, can manifest as extreme fatigue, a paler complexion, breathlessness on exertion, and difficulty concentrating[10].

Identifying and correcting these iron deficiencies, through diet and, if needed, targeted supplementation, can help you prevent anaemia and improve your energy levels and quality of life during this already demanding period for your body[11].

Other key nutrients

• Vitamin E acts as an antioxidant and supports healthy blood circulation.
• Vitamin K contributes to bone health in synergy with vitamin D.
• Zinc, for its part, contributes to hormonal regulation and supports the immune system, which is often weakened during periods of physiological stress.​

Once the menopause is confirmed, your nutritional needs change. The recommended iron intake decreases, as the permanent cessation of periods eliminates monthly blood losses: requirements then become closer to those of men.

However, it is important to ensure sufficient calcium and vitamin D intake, as the oestrogen deficiency that follows the menopause significantly increases the risk of bone loss and osteoporosis[12].

Cardiovascular prevention also becomes more central, as oestrogens no longer play their protective role on the heart and blood vessels, which contributes to the increased cardiovascular risk after the menopause[13].

These changes explain the value of nutritional formulas designed specifically for the perimenopause on one hand, and for established menopause on the other.

Why a specific multivitamin?

The "menopause" formulas available on the market are not suitable for women in perimenopause, as they are designed for a stabilised hormonal profile with no periods. "Pregnancy" or "breastfeeding" formulas do not meet your current needs either, due to unsuitable dosages (iron too high for pregnancy, vitamin B9 not adapted, etc.).

Perimenopause is therefore a distinct phase in its own right, requiring a targeted formulation to support the specific hormonal fluctuations of this transition.

A formulation designed for perimenopause

Formulated by Jolly Mama, Péri Essentials was developed to meet the specific needs of this pivotal phase. Its formulation combines vitamins B6, B9, and B12 for hormonal regulation and nervous system balance, vitamin D and K2 for bone preparation, as well as vitamins E and C, plus zinc and selenium for a comprehensive action.

Dosages are specifically tailored to the perimenopause profile, for optimal efficacy without any risk of overdose.

And to make it the best menopause food supplement, we have also added a patented Bacopa extract to support cognitive function, concentration, and memory.

How to incorporate Péri Essentials into your daily routine

Take Péri Essentials daily. This supplementation complements a balanced diet and is not a replacement for one. 

As every body is unique, do not hesitate to check in regularly with your doctor or midwife to adjust your nutritional approach as needed, in line with how your symptoms evolve.

Péri Support: relieving everyday symptoms

Alongside Péri Essentials, Péri Support can help if your perimenopause symptoms are already well established (hot flushes, night sweats, irritability, fatigue…). Hormone-free and 100% plant-based, this supplement is suitable from the age of 35, including for those with a history of breast cancer or thyroid conditions.

Its formula is based on 4 key plants:

• Sage for menopausal comfort and night sweats,
• Shatavari for stress, energy, and cycle regulation,
• Saffron for mood and relaxation,
• Milk thistle to support the liver and digestion.

At 2 capsules per day, Péri Support can be combined with Péri Essentials for comprehensive support throughout this transition.

Diet and perimenopause

Alongside your supplementation, prioritise foods rich in magnesium (dark chocolate, almonds, spinach), calcium (dairy products, sardines, cabbage), iron (red meat, pulses, pumpkin seeds) and B vitamins (eggs, oily fish, wholegrains). Limit stimulants (coffee, alcohol) which can worsen hot flushes and sleep disturbances. Finally, stay well hydrated throughout the day (1.5 to 2 litres of water) to compensate for perspiration and support elimination.

Lifestyle

Regular physical activity (walking, swimming, yoga, strength training) helps maintain bone and muscle mass, regulate mood, and improve sleep. Stress management is equally important: meditation, cardiac coherence, sophrology, or simply taking moments of rest in your daily routine can make a real difference.

In addition, establish a regular sleep routine and keep your bedroom cool to reduce night-time waking caused by hot flushes. Regular medical check-ups can help you adapt your support plan and detect any potential complications.

When to seek advice?

In any case, we recommend consulting your doctor, gynaecologist, or midwife if your periods become extremely heavy or prolonged, as this may require specific medical attention. If symptoms become intense and significantly impact your quality of life (severe insomnia, debilitating anxiety, depression), personalised support should be considered. 

Don't suffer in silence: solutions exist, hormonal or otherwise, to help you through this period more peacefully!
