Menopause vs. perimenopause
Menopause is confirmed in hindsight after 12 months without a period, and Korean women typically reach it around age 50. Perimenopause is the few years around it when ovarian function declines and estrogen swings widely, so symptoms can begin in the mid-to-late 40s as cycles become irregular.
Common symptoms and how long they last
- Hot flashes and night sweats: Sudden heat in the face and upper body with sweating, the most common symptom. In the SWAN study, which followed about 3,300 US women, they lasted a median of 7.4 years, and longer in women whose symptoms started before their final period.
- Sleep problems: Waking from night sweats or trouble falling asleep.
- Mood changes: Irritability, low mood, anxiety and poor concentration.
- Vaginal dryness and urinary discomfort: Tend to worsen after menopause and often do not go away on their own.
- Joint and muscle aches, fatigue are also common.
Separately from symptoms, bone loss speeds up and LDL cholesterol tends to rise after menopause, so bone density and blood tests are worth keeping up even without symptoms.
Menopause self-check
If several of these apply and they affect daily life, consider seeing a gynecologist. This is a reference checklist, not a scored diagnostic test.
- Your periods have become irregular, or you have had none for nearly a year.
- Your face flushes and you sweat several times a day.
- You wake at night from sweating or sleep poorly.
- You feel irritable or low for no reason and find it hard to concentrate.
- You have vaginal dryness, pain during sex, or need to urinate more often.
Thyroid disease and depression can cause similar symptoms, so do not assume it is menopause from symptoms alone.
Ingredients Korea's MFDS approves for menopausal women
The main ingredients approved for "may help the health of menopausal women" are below. Even with the same name, the daily amount differs by approved maker and approval number, so follow the label.
| Ingredient | Approval type | Notes |
|---|---|---|
| Japanese pagoda tree (Sophora japonica) fruit extract | Listed (any maker can use it if it meets the standard) | Contains plant estrogen-type compounds |
| Cynanchum wilfordii (baeksuo) complex extract | Individually approved | A blend with Phlomis umbrosa and Angelica gigas; a 2015 adulteration scandal (see below) |
| Pomegranate extract / concentrate | Individually approved | For example, pomegranate extract (No. 2015-28) at 1.5 g a day |
The approvals rest mostly on human trials run by Korean companies, with a few dozen participants over a short 8–12 weeks. "May help" means the MFDS accepted a certain level of evidence, not that the effect is large.
What international research and societies say
| Approach | Evidence for hot flashes |
|---|---|
| Hormone therapy (estrogen) | Most effective. A Cochrane review (2004) found weekly hot flash frequency fell about 75% compared with placebo. |
| Non-hormonal prescription drugs | Some antidepressants (SSRIs, SNRIs), gabapentin and a newer neuro-targeted drug have proven effects and are recommended by the US Menopause Society. Ask your doctor what is available in your country. |
| Plant estrogens (soy isoflavones, red clover, etc.) | A Cochrane review (2013) found no conclusive evidence that they reduce hot flashes. |
| Supplements and herbal remedies in general | The Menopause Society (2023) does not recommend them for hot flashes because the evidence is insufficient. |
In short, menopause supplements are an option to try for mild symptoms. If hot flashes keep you from sleeping, seeing a doctor is far more reliable than cycling through supplements.
Hormone therapy and breast cancer: how big is the risk?
Much of the fear around hormone therapy dates from the US WHI study published in 2002, where women on combined estrogen and progestin had a breast cancer hazard ratio of 1.26. The participants averaged 63 years old, many long past menopause. Based on later analyses, the Korean Society of Menopause and the North American Menopause Society consider the benefits likely to outweigh the risks for women under 60 or within 10 years of menopause who have no contraindications. A history of breast cancer, blood clots or stroke can rule it out, so decide only after seeing a doctor.
Menopause supplement myths: true or false?
| Claim | What the evidence shows so far |
|---|---|
| Natural ingredients are safer than hormones | No comparison shows they are safer. Some contain plant estrogen compounds, so if you have had breast cancer, endometriosis or another hormone-related condition, ask first. |
| Many baeksuo products are fake | In 2015 the Korea Consumer Agency tested 32 baeksuo products and found a look-alike root, Cynanchum auriculatum, in 21 (65.6%); the MFDS followed up with testing and inspections. Raw-material controls were tightened afterwards; check for the health functional food mark and the ingredient name. |
| Drinking lots of pomegranate juice works the same | Approved ingredients are specified extracts or concentrates with set daily amounts, not ordinary juice, which is also high in sugar. |
| Just wait it out | Hot flashes can last more than 7 years on average, and vaginal dryness often does not improve with time. Treatments exist, so talk to a doctor rather than enduring it. |
What you can do day to day
- Reduce triggers: Hot or spicy food, alcohol, caffeine and warm rooms can set off hot flashes. Dress in layers you can remove easily.
- Weight and exercise: Strength training and walking help bones, muscles and sleep.
- Bone nutrients: After menopause, check your calcium and vitamin D intake.
- Stop smoking: Smoking is linked to earlier menopause and worse hot flashes.
