Sleep gummies, answered.

Which gummy is best for sleep?

Most customers reach for StarShroooms in the evening, taking two gummies 30 to 60 minutes before bed. Each serving includes Reishi at 20:1, our most concentrated extract, alongside Maitake, Lion's Mane, Cordyceps, Chaga, Tremella and Panax Ginseng. If a busy mind is what keeps you up, Kalma adds ashwagandha root extract (10:1, standardised to 5% withanolides) and 2.8mg of vitamin B6, which contributes to normal psychological function. A popular routine is Kalma with breakfast and StarShroooms at night.

Do they contain melatonin?

No. StarShroooms and Kalma are made with mushroom and plant extracts, and neither contains melatonin. In the UK melatonin is a prescription only medicine, so food supplements sold here cannot contain it. There is no caffeine in either gummy. If you have been prescribed melatonin or any other sleep medicine, speak to your GP or pharmacist before adding a supplement to your evening routine, and bring the ingredient list with you.

What is in melatonin free sleep gummies?

Instead of a hormone, they use ingredients with a long history of evening use. StarShroooms relies on Reishi, known as lingzhi in China and used for more than 2,000 years as a calming, restorative mushroom. Kalma uses ashwagandha root, whose Latin name, somnifera, means sleep bringing. Other brands often use L-theanine, chamomile, lemon balm or magnesium. None of these acts like a sleeping tablet, so do not expect to feel drowsy straight after a dose. The studies on them measured sleep over weeks of daily use.

What has the research found on Reishi and sleep?

Most of it is early. In a 2012 study in rats, a high dose of Reishi extract increased total sleep time by 97%. The first larger human trial was presented at the SLEEP 2026 conference: 218 adults with chronic insomnia took 980mg of Reishi extract or 5mg of melatonin every night for 8 weeks, and the Reishi group improved more on the Insomnia Severity Index. It has not yet been published in a peer reviewed journal, and it did not test StarShroooms. Our Reishi guide links to both studies.

What does the research say about ashwagandha and sleep?

There are more human trials here. In a 2019 study of 60 adults with insomnia, people taking 300mg of ashwagandha root extract twice a day for 10 weeks fell asleep faster and rated their sleep quality higher than the placebo group. A 2021 review pooling five trials and 400 adults found a small but significant effect on overall sleep, stronger in people with insomnia, at 600mg a day or more, and in trials of eight weeks or longer. These trials used capsules and did not test Kalma. See our ashwagandha guide.

When should I take sleep gummies?

Take two StarShroooms 30 to 60 minutes before bed, ideally at the same time each night, so they become part of winding down along with dimming the lights and putting your phone away. Kalma's label suggests breakfast, and the ashwagandha sleep trials measured daily use over several weeks rather than a single dose at bedtime, so a regular time is what counts. Taking both? Kalma in the morning and StarShroooms at night is our most popular routine, explained in Kalma in the morning, StarShroooms at night.

Will I feel groggy the next morning, or come to rely on them?

Neither gummy contains melatonin, antihistamines or any sedative medicine, and they are not made to knock you out. They are food supplements built around mushroom and plant extracts, meant for daily use, and you can stop whenever you like. Everyone reacts a little differently to something new, so try your first few doses on a night when you do not need to be up early. If poor sleep carries on for more than a few weeks, speak to your GP.

How many sleep gummies can I take?

Two a day of each product, and no more. The StarShroooms and Kalma labels both say not to exceed the recommended intake. If you take StarShroooms and Kalma together, that is four gummies in total, which is fine because they are different products made to be combined. If you also take SuperMoss, bear in mind that SuperMoss and StarShroooms both contain iodine, so check the combined amount with your pharmacist.

How long until I notice a difference?

Some customers mention changes in their first week, but plan on a full month of nightly use. The human trials on Reishi and ashwagandha ran for eight to ten weeks. The 2021 ashwagandha review found stronger results in trials lasting eight weeks or more, so Kalma is worth two packs before you judge it. A 60 gummy pack of either lasts 30 days. If it is not for you, our 30 day money back promise covers your order, and there is no need to send opened pouches back unless we ask.

Can I take StarShroooms and Kalma together?

Yes. All Innooova gummies can be taken alongside one another, and neither of these contains caffeine. The Mind, Body & Soul bundle puts a 30 day pack of StarShroooms, Kalma and Grooovy Greeens together for £69.95 instead of £74.97, and a 5 day trial version costs £12.99 if you want to test the routine first. All three are vegan and set with fruit pectin. Orders go out with tracked UK delivery, usually arriving in 2 to 3 working days, and subscriptions can be skipped, paused or cancelled any time.

Who should check with a GP first?

Kalma is not for use during pregnancy or breastfeeding, or for anyone under 18, and our other gummies are made for adults too. Speak to your GP or pharmacist before taking either sleep gummy if you:

  • are pregnant or breastfeeding
  • take prescription medication, particularly sedatives, sleeping tablets or thyroid medicine
  • have a thyroid, liver or autoimmune condition, as ashwagandha is best avoided unless your doctor agrees
  • are under medical supervision

StarShroooms contains iodine, so mention that as well. Food supplements should not replace a varied, balanced diet and a healthy lifestyle.

Your first five nights are £4.99.
