Focus gummies, answered.

Which gummy is best for focus?

For a clear head at work or study, most people choose StarShroooms. Two gummies give you a 2:1 Lion's Mane extract and full spectrum Panax Ginseng, plus 100µg of iodine (67% NRV) and 12mg of vitamin B5 (200% NRV). Iodine contributes to normal cognitive function, and vitamin B5 contributes to normal mental performance. The other five mushrooms, Reishi, Cordyceps, Chaga, Maitake and Tremella, sit in the same blackcurrant gummy. If you also want a source of zinc, two GlowShroooms give you 1.5mg (15% NRV), and zinc contributes to normal cognitive function too.

What do Lion's Mane gummies actually do?

They give you Lion's Mane (Hericium erinaceus) in a form you can chew. In people it has been studied for memory, focus and mood. A 2009 Japanese trial in 30 adults aged 50 to 80 with mild cognitive impairment found higher scores on a cognitive function scale than placebo at weeks 8, 12 and 16. A 2023 pilot study in 41 adults aged 18 to 45 found faster times on one focus task an hour after a single dose, although most of the other tests showed no difference. None of these trials tested our gummies, and the evidence is still early. Our Lion's Mane guide links to each study.

How much Lion's Mane is in StarShroooms?

Each serving of two StarShroooms contains a 2:1 Lion's Mane extract, which means two parts of dried mushroom go into every one part of extract. The label gives extract ratios for the mushrooms rather than a milligram figure for each one, so we do not quote one here. For context, the 2023 study above used 1.8g of Lion's Mane a day, and the 2009 trial used powder tablets. The other extracts in the gummy are stronger: Reishi at 20:1, Chaga and Maitake at 10:1. The full label, including the B5 and iodine amounts, is on the product page.

Do they contain caffeine?

No. There is no caffeine in StarShroooms or in any other Innooova gummy, so they will not add to your coffee or tea total and you can take them at any point in the day. That was the reason StarShroooms was made in the first place: a caffeine free alternative to mushroom coffee. Plenty of customers keep their morning coffee and simply add two gummies with breakfast. Mushroom gummies vs mushroom coffee compares the two formats in more detail.

When is the best time to take Lion's Mane gummies?

Most people take them in the morning. For daytime focus, have two StarShroooms with breakfast, at roughly the same time each day so the habit sticks. The Lion's Mane trials gave it daily, so regular use counts for more than the exact hour. Because StarShroooms also contains Reishi, our most concentrated extract at 20:1, some customers prefer to take their two gummies 30 to 60 minutes before bed instead. Pick one slot, keep to it, and do not take more than two gummies a day.

How long until I notice anything?

Give it at least a month of daily use. The human studies on these ingredients ran for four to sixteen weeks, and in the 2009 Lion's Mane trial the differences showed from week 8. Scores in that trial also fell back four weeks after people stopped, which is why we suggest taking the gummies every day rather than now and then. One 60 gummy pack lasts 30 days. If you plan to carry on, the 180 gummy Triple Pack covers three months for £69.95, or a subscription brings the Full Pack down to £19.99.

Can I take Lion's Mane gummies every day, and are there side effects?

StarShroooms is made to be taken daily, up to two gummies. Lion's Mane is an edible mushroom that has been eaten in China and Japan for generations, and the 16 week trial we link to reported no adverse effects. Some people notice mild stomach upset when they start any new supplement, and this tends to settle within a few days. Avoid it if you are allergic to mushrooms. Each serving is sweetened with sugar and steviol glycosides, and it is free from gelatine, dairy, gluten, caffeine and artificial flavouring.

Are Lion's Mane gummies magic mushrooms?

No. Lion's Mane contains no psilocybin, and you can buy it fresh in food shops and eat it in restaurants. The same goes for every mushroom in StarShroooms: Reishi, Cordyceps, Chaga, Maitake and Tremella are functional mushrooms with a long history in food and traditional practice. They are legal to buy in the UK and they will not make you feel high. StarShroooms is third party tested and made in a GMP certified facility, and every ingredient is listed on the label.

Are gummies as good as Lion's Mane capsules or powder?

They suit people who want something they will remember to take. Capsules and powders can hold more of a single mushroom per serving, and a powder can go into coffee or a smoothie. A gummy trades some of that space for taste and convenience: no water, no shaker and nothing bitter. StarShroooms also puts six mushroom extracts and Panax Ginseng in one gummy, where a typical mushroom gummy has one to three. If a large single dose of Lion's Mane matters most to you, a capsule may be the better fit.

Can I try before committing?

Yes. The StarShroooms Trial Pack has 10 gummies, about five days' worth, for £4.99. It is the easiest way to check you like the blackcurrant taste before buying a Full Pack. To sample more of the range, the Try-All Bundle holds six trial packs for £29.94. Every order comes with tracked UK delivery, usually in 2 to 3 working days, and our 30 day money back promise: if you are not happy, message us within 30 days and we will refund you.

Who should check with a GP first?

Speak to your GP or pharmacist before taking StarShroooms if you are pregnant, breastfeeding, taking prescription medication or under medical supervision, and show them the full ingredient list. The gummies contain iodine, so ask them too if you have a thyroid condition, and add up your total if you also take SuperMoss, which contains iodine as well. Our gummies are made for adults and are not for under 18s. Food supplements should not replace a varied, balanced diet and a healthy lifestyle.

Your first five days are £4.99.
