"After 3 full cycles with Bye Painful Periods, it's night and day. Before, my first two days were absolutely debilitating - nearly fainting from pain. Now I manage without any medication. My flow is more concentrated, much less spotting, and almost zero PMS. If I could keep only one supplement, it would be this one."

"I tested Bye Painful Periods due to significant cramping. Pain was still present but much less intense - to the point where I stopped thinking about it all day. I also noticed better mood and a clear improvement digestively. That was actually the most relieving effect for me."

"Before Bye Painful Periods, my first period day meant staying in bed, sometimes nearly fainting on the metro. By cycle three, I felt almost nothing - I attended a full-day conference and danced for an hour that same evening. Unimaginable before. My period also went from a week down to four days."

The ingredients

Chamomile

Contributes to optimal relaxation

Chamomile is a plant traditionally used for its calming and antispasmodic properties. It contains active compounds such as apigenin, which act on the nervous system to promote muscular and nervous relaxation. Through this effect, chamomile helps soothe the tension and abdominal cramps commonly experienced during periods. It therefore contributes to maintaining a sense of comfort and ease throughout the menstrual cycle. 80 mg of chamomile extract corresponds to 400 mg of dried flowers, concentrating the apigenin and soothing compounds recognised for promoting relaxation and easing pelvic cramps.

Ginger

Supports the body's natural defences

Ginger is a plant well known for its anti-inflammatory and antioxidant properties. It contains active compounds such as gingerols and shogaols, which help naturally reduce the production of prostaglandins involved in menstrual pain. These molecules also act on reducing abdominal cramps and help soothe discomfort during periods. Long used in herbal medicine, ginger is a well-tolerated natural option to support everyday feminine comfort. 90 mg of ginger extract is equivalent to 900 mg of dried rhizome, preserving its active gingerols involved in the natural reduction of menstrual pain intensity.

Yarrow

Helps soothe menstrual cramps

Yarrow (Achillea millefolium L.) is a plant traditionally used for its antispasmodic and anti-inflammatory properties. Thanks to its high flavonoid content, it helps relieve muscle spasms and abdominal cramps associated with painful periods. It also promotes relaxation of the uterine muscles, thereby contributing to greater comfort during the menstrual cycle. 625 mg of yarrow extract is equivalent to 3.125 g of dried plant, ensuring an optimal concentration of flavonoids traditionally recognised for easing cramps and supporting menstrual comfort.

Palmitoylethanolamide (PEA)

Helps reduce menstrual discomfort

Palmitoylethanolamide (PEA) is a compound naturally produced by the body in response to stress or inflammation. It helps modulate pain and calm nervous hyperactivity, making it a natural ally for soothing menstrual discomfort, particularly cramps. Found in small quantities in certain foods, it is well tolerated and naturally broken down by the body.

Answers to your questions

What ingredients are in Bye Painful Periods?

Bye Painful Periods brings together four actives in one formula: yarrow, ginger, chamomile, and OptiPEA® PEA, each included at a standardised, measured dose. There are no fillers or proprietary blends - just the actives themselves, in a plant-based capsule.

What supplement is best for menstrual cramps?

Ginger is one of the most commonly discussed options, alongside a handful of other botanical and lipid-based ingredients. Bye Painful Periods brings several of these together in one formula - yarrow, ginger, chamomile, and OptiPEA® PEA - rather than relying on just one. It's always worth checking with a healthcare professional if you're unsure what's right for you, especially if you're on other medication.

How long before my period should I start taking Bye Painful Periods?

Start around 5 days before your period is due and continue through your period — 4 capsules a day, split into two doses, taken with food. Starting ahead of your period gives the formula time to settle in before cramping typically begins. If your cycle isn't regular, take it for 5 to 10 days whenever needed, independent of a fixed date.

What generally causes period pain?

Period pain is mainly linked to natural chemicals called prostaglandins, which cause the uterus to contract as it sheds its lining - the higher the levels, the more intense the cramping tends to be. For most people that's a normal, if unwelcome, part of the cycle. Pain that's unusually severe, worsens over time, or doesn't ease with the usual measures is worth raising with a doctor, since there can be other things behind it worth ruling out.

Can I take Bye Painful Periods if I'm on hormonal contraception?

Yes, it's compatible with both hormonal and non-hormonal contraception. If you're going through IVF or an assisted reproduction programme, speak to your doctor before starting. It isn't recommended during pregnancy or breastfeeding, or if you have a known allergy to plants in the Asteraceae family (such as ragweed or daisies). If you're taking any other medication, check with a healthcare professional first.

Are there quick ways to ease period pain

Plenty of women find heat (a hot water bottle on the lower abdomen), staying hydrated, gentle movement, and rest genuinely helpful in the moment. Some also use over-the-counter pain relief when needed - a pharmacist can advise on what's suitable. Bye Painful Periods is designed to be one part of that broader routine, taken in the days around your period, rather than a one-off fix.

Can magnesium prevent period cramps?

Magnesium is one of the most commonly discussed minerals for period cramps, which is why we also offer it as a standalone supplement. Bye Painful Periods takes a different approach - combining yarrow, ginger, chamomile, and OptiPEA® PEA in one formula built specifically for period comfort. Depending on what you're looking for, either can be part of your routine, and some women use both.

Which vitamins are good for period pain?

Magnesium, vitamin D, and B vitamins are among the nutrients most often mentioned for period pain - magnesium is available as one of our standalone supplements if that's the route you want. Bye Painful Periods takes a different route: yarrow, ginger, chamomile, and OptiPEA® PEA, brought together in a formula designed specifically around period comfort.
