Hey Sister! Period helps relieve various symptoms associated with menstruation such as period pains, cramps, bloating, PMS, mood swings, fatigue, poor sleep and even any mild anxiety associated with menstruation*.

Hey Sister! Period is a new, natural remedy proven to reduce multiple menstruation symptoms at once. It harnesses the power of strong, plant-based anti-inflammatories in its hero ingredient, Khapregesic®, to bring effective relief that targets the root cause.

What Causes Period Symptoms

For most women, menstruation can bring symptoms like cramps, bloating, mood swings, heavy bleeding and fatigue. The cause of these symptoms typically stems from an overproduction of prostaglandins - a hormone-like substance that influences inflammation, pain, and uterine contractions. The excess of prostaglandins during menstruation increases inflammation, sparking these common period symptoms and often making them more intense than normal.

How Khapregesic® Works

Khapregesic® is powered by a single, natural ingredient known for its strong anti-inflammatory effects^[1], high antioxidants^[1], and naturally occurring prebiotics^[2]. This unique combination helps to ease period symptoms by reducing prostaglandin levels, which, in turn, decreases inflammation and alleviates discomfort. The result? Symptom-free relief thats natural.

Why Choose Hey Sister!

We know that every woman’s period is different, and there’s no one-size-fits-all approach to menstrual relief.

But we also understand that there's a need for a natural, effective alternative to traditional painkillers - one that offers relief without the need for synthetic drugs.

That’s exactly why we created Hey Sister! Period. Our plant-based solution provides powerful, natural symptom relief while supporting long-term wellness without the harmful side effects often associated with drug-based painkillers.

Unlike standard pain medications, Hey Sister! goes beyond simple symptom relief. Each tablet is packed with antioxidants and prebiotics to boost gut health, immunity, and energy levels.

For holistic, comprehensive support through your cycle, Hey Sister! is here to help you feel balanced, healthy, and at ease, every month.

As always, follow the directions on the bottle or the written directions from your practitioner and remember, if symptoms persist, talk to your health professional.
