Yes, and we have customers who take both. Calm Days is non-hormonal (it contains no hormones), and we're not aware of any established interactions between HRT and its four ingredients. As HRT is a prescription medicine, it's still worth a quick check with your GP or pharmacist before you start.

Yes, it can be. Calm Days is completely non-hormonal: it contains no hormones and no plant oestrogens such as soy isoflavones or red clover. It's designed to support the emotional side of perimenopause and menopause, like feeling on edge, overwhelmed or wired at night, without adding hormones.

We're not aware of any established interactions with tamoxifen or aromatase inhibitors. As these are specialist medicines, it's worth a quick check with your oncology team or pharmacist before you start, and we're happy to send them the full ingredient details.

Then you get your money back. If Calm Days isn't right for you, email us within 30 days of receiving your order and we'll refund you. You don't need to send back an opened bottle.

The same goes if it doesn't agree with you: just stop taking it and let us know. We know a lot of women have spent money on things that didn't work, and we don't want Calm Days to end up sitting in your cupboard.

Just 2.5 mg per daily serving, a deliberately gentle amount. That's a little above the recommended daily intake for women (1.3 to 1.5 mg) and a small fraction of the 50 mg daily upper limit for adults in New Zealand and Australia.

If you've heard about B6 side effects, those relate to much higher doses taken over long periods.

Yes, most people can. Each daily serving of Calm Days gives you 200 mg of elemental magnesium as magnesium glycinate, a form known for being gentle and well absorbed. (The 670 mg on the label is the weight of the whole glycinate compound, glycine included.) Plenty of people simply let it replace their usual magnesium.

If you'd like to keep both, that's fine too. You might see a general guide of 350 mg of elemental magnesium (sometimes listed as "equivalent magnesium") a day from supplements. That number is there because larger amounts can upset some people's tummies.

Want us to look at your other supplement? Email us a photo of the label and we'll check it for you.

Usually, yes. Calm Days has just four ingredients and saffron is the only herbal one, so it won't double up on black cohosh, ashwagandha or most menopause formulas. We're not aware of any established interactions between Calm Days and black cohosh, ashwagandha, evening primrose oil or zinc.

Two things are worth checking on your other labels:

• Magnesium, vitamin B6 or L-theanine: these turn up in a lot of menopause multis and sleep blends, so add up your daily totals (see the magnesium question above).
• 5-HTP or St John's wort: like saffron, these can affect serotonin, so check with your pharmacist before combining them.

Not sure? Email us a photo of your labels and we'll check them for you.

Calm Days is designed for the emotional side of perimenopause. Its ingredients have been studied for supporting stress management, better sleep quality and a sense of calm. It's non-hormonal, so it isn't designed to treat hot flushes directly, but many women find that supporting their sleep and stress response makes a real difference to how everything else feels.

If irritability, feeling on edge or lying awake at 2am is what's wearing you down, that's what we made it for. And it's not just for perimenopause: we have customers taking it through menopause and well beyond.

It depends on the medication, so check with your GP or pharmacist first. Here's what's worth mentioning to them:

• Antidepressants (e.g. SSRIs): saffron can have a mild effect on serotonin.
• Blood pressure medication: L-theanine and saffron may have a mild blood-pressure-lowering effect.
• Thyroid medication (levothyroxine): magnesium is generally taken at least four hours apart from it.

You're also welcome to email us your medication list and we'll check for known interactions. Calm Days isn't a replacement for prescribed medication, so please don't stop or change anything without talking to your doctor.

Yes, anytime. There's no lock-in. You can skip an order, pause, change how often it arrives, or cancel in a couple of clicks from your account. Prefer a hand? Just reply to any of our emails and we'll sort it for you.

We also send a reminder email a couple of days before each order is processed, so there are no surprises.

Quickly. We send every order by overnight express courier anywhere in New Zealand, so it's with you the next working day after it's dispatched (weekends excluded).

It varies. Some women notice a shift within the first week or two; for others it builds gradually over a few weeks. The first signs are usually gentle: feeling a bit more balanced in moments that would normally tip you over, or finding it easier to unwind in the evening.

Take it daily and give it a fair go. Our 30-day guarantee gives you time to find out.

Yes, take it whenever suits you. Calm Days contains no caffeine or stimulants, so it won't keep you awake, and it's designed to calm you without making you drowsy.

If sleep is your main struggle, try taking it about an hour before bed. If you ever feel tired during the day, try switching to evenings. You can also split it: one capsule at night and one in the morning.

Calm Days is made in Pukekohe, New Zealand, by a specialist supplement manufacturer. We also pay for independent testing of the finished product through Eurofins New Zealand. We choose the samples ourselves, from the same stock we send to customers, rather than letting the manufacturer pick them.

Email us and we'll send you the certificate for the current batch.

Just four active ingredients per daily serving (two capsules):

• L-theanine 300 mg
• Magnesium glycinate 670 mg (200 mg elemental magnesium)
• Saffron extract 30 mg (5:1, equivalent to 150 mg saffron)
• Vitamin B6 2.5 mg

The capsules are plant-based (HPMC) with no gelatin, and our manufacturer's allergen declaration lists no gluten-containing cereals, dairy, soy or corn-derived ingredients. The magnesium is glycinate, which is generally gentler on the stomach than forms like magnesium oxide.

If you react to particular ingredients, email us and we'll happily send the full details for you or your pharmacist to check.

We get asked this a lot, and the research on the ingredients is encouraging. L-theanine and saffron have each been studied in children and teenagers at daily amounts similar to those in Calm Days, including research on sleep, focus and emotional wellbeing. For children aged 9 and over, the magnesium and vitamin B6 in a daily serving are within the recommended upper limits for their age in New Zealand and Australia.

Calm Days is formulated for adults and is best suited to ages 9 and up, as the magnesium is higher than recommended for younger children. We'd suggest a quick chat with your GP, paediatrician or pharmacist before starting, especially if your child takes ADHD or any other medication. And if it's not the right fit, our 30-day money-back guarantee has you covered.

If you take ADHD medication such as Ritalin, we're not aware of any established interactions with Calm Days' ingredients. As with any supplement alongside a prescription, it's worth a quick check with your prescriber or pharmacist before you start.

There's also a growing body of research on L-theanine and ADHD, including research showing better sleep quality and encouraging results for focus. Saffron has also shown promise in ADHD research. Calm Days is designed to sit alongside your usual care, not replace it.
