In short:
- A PMS and menstrual comfort supplement belongs to one of three families: buds (HerbalGem), plants with chasteberry (Dietaroma, Best of Natural) or saffron combined with nutrients or pollen (Oligobs SPM, Sérélys SPM).
- Intake schedules vary threefold: 10 days per cycle for Oligobs, a continuous daily intake for HerbalGem and, over the first two months, for Sérélys.
- HerbalGem offers three certified organic cycle references, chasteberry-free, between 18.90 and 22.50 euros.
- European Regulation (EU) No 432/2012 governs what labels can promise: vitamin B6 is listed for the regulation of hormonal activity.
What happens in the second half of the cycle
Premenstrual syndrome refers to a set of discomforts that settle in after ovulation and fade once the period begins. Breast tenderness, a bloated stomach, tiredness, a more changeable mood: the picture differs from one woman to another, and sometimes from one month to the next for the same person.
This stretch corresponds to the luteal phase, which lasts 14 days on average. It is the phase most supplements in this aisle focus on, which explains why several brands suggest an intake limited to those two weeks.
Putting a precise word on what you feel makes the choice easier. A mainly physical discomfort, a need for support with mood or an irregular cycle rhythm do not point towards the same formulas.
Three formula families behind the five brands
The compositions fall into three clearly separate groups. The brand matters less than the family it belongs to.
| Family | Brands | Core actives | Profile it may suit |
|---|---|---|---|
| Buds and young shoots | HerbalGem | Raspberry, downy birch, rosemary, yarrow | Looking for a long-term, organic, chasteberry-free course |
| Plants with chasteberry | Dietaroma, Best of Natural | Chasteberry, yarrow, lady’s mantle, chamomile, boswellia | Wanting a formula centred on the most studied plant |
| Saffron and nutrients | Oligobs SPM, Sérélys SPM | Saffron, magnesium, zinc, vitamins B6 and E, pollen | Preferring a short intake or a non-plant approach |
Each family has its own logic. Ranking them on the displayed price alone therefore makes little sense.
HerbalGem: raspberry offered through three entry points
Founded in Belgium in the 1980s and now part of the Inula group, HerbalGem only produces bud and young shoot macerates. For the female cycle, the laboratory has chosen one common thread, raspberry, which it offers at three levels of commitment.
For a first approach: raspberry on its own
The single-ingredient reference, sold at 18.90 euros for a 30 ml bottle, relies solely on raspberry young shoots. Traditional use connects this plant to women’s lives as a whole, from the first years of periods through to menopause. The indicated dose ranges from 5 to 15 drops each day, diluted in water. The same plant goes into the laboratory’s perimenopause capsule, described in our guide to female hormonal balance supplement brands.
For a fuller formula: the drop complex
Sold at 19.90 euros for a 30 ml bottle, this complex pairs raspberry with vine and wayfaring tree buds, chamomile, marjoram and guelder rose tinctures, plus a small amount of fennel essential oil. Intake ranges from 10 to 25 drops a day, away from meals. It is not intended for children under 13, nor for pregnant or breastfeeding women.
For intake without counting drops: the capsules
The most recent format, sold at 22.50 euros for a box of 30, brings together downy birch bud, raspberry and rosemary young shoots and a yarrow extract. One capsule in the morning is enough, and the alcohol content stays below 0.1%. The laboratory recommends continuing the course for three months.
The three references, all certified organic, are grouped in the laboratory’s female wellbeing selection. The logic stays the same from one format to the next: the bud is taken over time to follow the rhythm of the cycle, rather than occasionally for an isolated discomfort.
The four other brands, family by family
Dietaroma and Best of Natural, the chasteberry choice
Dietaroma offers an organic tablet sold at 14.55 euros for a box of 30, combining six plants: yarrow first (500 mg dry plant equivalent), then lemon balm, ginger, lady’s mantle, dandelion and 50 mg of chasteberry. The formula is designed for a short intake around the start of the period.
Best of Natural makes chasteberry the main ingredient of its Harmonie formula: 420 mg of fruit powder at the maximum daily dose, supplemented with boswellia, chamomile, fennel and two vitamins. The 60-capsule bottle is priced at 29.90 euros.
Oligobs SPM and Sérélys SPM, the saffron choice
At Laboratoire CCD, the Oligobs SPM formula rests on a saffron and butcher’s broom pairing, backed by three nutrients: 300 mg of magnesium, 15 mg of zinc and 1.4 mg of vitamin B6 across three tablets. It is the cheapest option in the aisle, at 12.83 euros for a box that covers one cycle.
Sérélys SPM combines Swedish pollen extracts, 50 mg of saffron and vitamin E in a single capsule. The brand stresses that its formula has no hormonal activity. Vitamin E, which also features among sources of natural antioxidant, contributes to the protection of cells from oxidative stress. The box of 30 capsules costs 34 euros.
The butcher’s broom in Oligobs is a reminder that the cycle aisle overlaps with the one for lighter legs: this plant is also among the usual actives of a blood circulation supplement.
What European regulation allows labels to say
Labels in this aisle often seem vague. That caution is no accident: it comes from a specific text.
The health claims framework Commission Regulation (EU) No 432/2012, adopted on 16 May 2012, sets the list of claims permitted on foods. Vitamin B6 appears with the wording “contributes to the regulation of hormonal activity”, magnesium with “contributes to the reduction of tiredness and fatigue”.
Plants do not have this kind of validated claim. Their wording is still awaiting European assessment, which forces brands to talk about “comfort” or “balance” rather than specific effects. A label that promises more deserves a careful read.
This framework also explains why two very different formulas can display almost identical promises. The composition, however, remains the only reliable ground for comparison.
The intake schedule, an often underestimated criterion
Beyond the price of the box, the real practical question is this: how many days a month do you need to remember your supplement? The gaps are clear.
| Brand | Intake days per cycle | Doses per day | Period covered by one box |
|---|---|---|---|
| Oligobs SPM | 10 | 3 tablets | 1 cycle |
| Dietaroma | 15 | 1 tablet | 2 cycles |
| Sérélys SPM | 30, then 14 from the 3rd cycle | 1 capsule | 1 month, then 2 cycles |
| HerbalGem capsules | 30 | 1 capsule | 1 month |
| Best of Natural | depending on use | up to 6 capsules | 10 days at the maximum dose |
A short intake suits people who easily forget a daily dose. A continuous intake, like HerbalGem capsules, fits better into an established routine, and gemmotherapy is designed to be followed over several weeks.
This schedule also shapes the real budget.
Precautions that apply whatever the brand
During pregnancy or breastfeeding, it is best to ask a health professional before starting, especially as several manufacturers explicitly exclude these periods. Chasteberry-based formulas call for the same caution alongside hormonal medication, contraception included.
Drop macerates contain alcohol, up to 40% vol. depending on the reference, something certain people need to know. Capsules then offer a simpler alternative.
Finally, some cycle discomforts resemble digestive ones: lower abdomen bloating at the end of the cycle often mixes both, and the habits used to reduce bloating naturally remain useful alongside a course. Discomfort that stops you from working or a very low mood every month, on the other hand, is a good reason to see a doctor or a midwife.
