Every claim has a source
When we say an ingredient does something, the words link to the study or the official source behind it. No vague "studies show".
Our science
What's inside, and what the evidence says
Every product we sell has a label you can read and ingredients you can look up. On this page we show the research behind each ingredient, tell you how strong that research is, and say plainly where the evidence is thin. Tap any underlined words to open the study.
Three promises we keep on this page
We tell you how strong the evidence is
Each ingredient carries one of three labels: Well established (a recognised nutrient role), Early research (small or adult-only studies, or studies of the ingredient rather than our product) and Not proven (things people believe that the evidence does not support).
Label first, no medical promises
These are food supplements, not medicines. We only describe what the label and food supplement rules allow, and we never say a product treats, cures or prevents any condition.
Lingo Leap, for kids 3+
What's in one dropper
One dropper (1ml) a day, taken as it is or mixed into a drink. Berry flavour, sugar-free and gluten-free. Three active ingredients, listed below with the exact amount from the label. Other ingredients: vegetable glycerin, purified water and natural flavours.
Vitamin B12
300mcg, as methylcobalamin
Well established. Vitamin B12 contributes to the normal functioning of the nervous system, normal energy-yielding metabolism and normal red blood cell formation. These are nutrient roles recognised by food regulators, not results from a study of Lingo Leap.
Methylcobalamin is one of the natural forms of B12 found in the body and in animal foods. A 2017 review found that for most people the natural forms and the common synthetic form are likely to be used in a similar way, so we do not claim methylcobalamin works better for your child.
300mcg is well above a young child's daily requirement, about 0.9 to 1.8mcg a day for ages 1 to 13. If your child already takes another product with B12, ask your paediatrician.
What we do not claim: B12 does not build speech, language or intelligence, and it does not treat any developmental condition.
Vitamin D3
5mcg (200 IU), as cholecalciferol
Well established. Vitamin D helps the body absorb calcium, which children need for normal bone formation. The body makes vitamin D when skin is exposed to sunlight, and very few foods contain it naturally.
One dropper gives 5mcg, a third of the recommended 15mcg (600 IU) a day for children aged 1 to 13. It tops up diet and sunlight; it is not a full daily amount on its own and not a high dose.
What we do not claim: extra vitamin D does not improve learning, focus or speech in children who already have enough, and it does not treat a deficiency. If you suspect low vitamin D, ask your paediatrician about a blood test.
Zeolite
100mg, as clinoptilolite
Early research, adults only. Clinoptilolite is a natural volcanic mineral with a porous structure. In a 12-week trial of 52 trained adults, 1.85g a day lowered one marker of gut barrier function compared with placebo. That is more than 18 times the amount in one dropper, and the people studied were adults.
A 2018 review of clinoptilolite safety covers its uses in people and animals. We could not find any published study of clinoptilolite in children, so we label the evidence for kids as early and unproven.
What we do not claim: zeolite does not "detox" a child, remove heavy metals, or help speech, attention or behaviour.
No one has tested Lingo Leap itself in a clinical trial. Everything above describes research on the ingredients, not on this product. Give 1 dropper a day to children aged 3 and over, and check with your paediatrician first if your child takes medicine or other vitamins.
Context, not a promise
Why vitamin D and B12 matter for children in Pakistan
Pakistan's National Nutrition Survey 2018 (Government of Pakistan with UNICEF) tested blood samples across the country. It found vitamin D deficiency in 62.7% of children under five, with 13.2% severely deficient, and in 79.7% of women of reproductive age. Even in a sunny country, time indoors, covered skin and diet all affect how much vitamin D the body makes.
The survey's key findings did not report vitamin B12 levels, so we do not quote a figure. What is clear is that vitamin B12 is found naturally only in animal foods such as meat, fish, eggs, milk and yoghurt, so children who eat little of these can fall short.
These numbers describe the population, not your child. The only way to know your child's levels is a blood test.
- Ask your paediatrician about a blood test before starting any vitamin.
- Eggs, fish, milk and yoghurt, plus some safe time outdoors, are the everyday sources of these two vitamins.
- A supplement adds to a varied diet. It does not replace one.
MindMorn shots, for adults 18+
Four shots, four jobs
Each shot is a 60ml bottle and one bottle is one serving. The caffeine amount is the main difference, so we show it first. Take no more than one shot a day. Not for anyone under 18, or if you are pregnant or breastfeeding. If you are sensitive to caffeine or take any medicine, ask your doctor first.
Rise Focus Shot
55mg caffeine, for everyday focus
Caffeine from ceremonial-grade matcha and natural caffeine, with L-theanine, lion's mane, bacopa, citicoline, ashwagandha, rhodiola, turmeric and cordyceps. A morning shot for moderate caffeine users and anyone new to the range.
Peak Focus Shot
165mg caffeine, for heavy caffeine users
The same ingredients as Rise in a larger blend, with three times the caffeine. Take it in the morning, not after about 2pm, and count it towards your day's coffee and tea. Not for anyone who finds coffee makes them jittery.
Clear Focus Shot
0mg caffeine, 0g sugar, for any time of day
The same herbal and nootropic blend without matcha or caffeine. A choice for people who avoid caffeine or want a shot in the afternoon.
Dusk Sleep Shot
0mg caffeine, 0.5mg melatonin, for winding down
A low 0.5mg dose of plant-based melatonin with ashwagandha, magnesium glycinate, L-theanine, lavender, lemon balm and chamomile. Take it about 30 minutes before bed. Adults only; not for use during pregnancy or breastfeeding.
The main ingredients, and how strong the evidence is
Caffeine and L-theanine
In Rise and Peak (L-theanine in all four)
Well established for caffeine and alertness. In a small trial of 27 adults, 50mg of caffeine improved alertness, and adding 100mg of L-theanine improved speed and accuracy on an attention task.
Early research for the pairing. Another trial found that at tea-like doses, L-theanine cancelled out caffeine's effects on attention rather than adding to them. The combined effect is not settled.
Safety: Europe's food safety authority found single doses up to 200mg and up to 400mg a day raise no safety concerns for healthy adults, and up to 200mg a day in pregnancy. Remember tea, coffee and cola count too.
Lion's mane
Organic fruiting body. In Rise, Peak and Clear
Early research. A single 1g dose improved reaction time on some tasks in a small placebo-controlled crossover trial. A 2024 review found the results of mushroom intervention studies were mixed, with some benefits for mood and thinking in middle-aged and older adults, and called for larger trials.
Bacopa monnieri
Whole herb. In Rise, Peak and Clear
Early research. In a 12-week trial of 54 adults aged 65 and over, 300mg a day of a standardised extract improved delayed word recall compared with placebo. Studies are small and mostly in older adults, and effects build over weeks rather than hours.
Ashwagandha
Organic root. In all four shots
Early research. In a 90-day trial of 130 adults with moderate everyday stress, 300mg a day improved memory test scores and lowered perceived stress scores compared with placebo. The study was run with the extract's maker, and one trial is not enough to call the effect proven.
Rhodiola rosea
Root. In Rise, Peak and Clear
Early research. A systematic review of 11 randomised trials found rhodiola may help physical and mental performance, but noted a lack of independent repeat studies and said more research is needed.
Citicoline (Cognizin)
Patented form. In Rise, Peak and Clear
Early research. In a 12-week trial of 100 healthy adults aged 50 to 85 with age-related memory complaints, 500mg a day improved memory scores compared with placebo. A trial of a citicoline and caffeine drink in 60 adults found faster reaction times, but it cannot separate the citicoline from the caffeine.
Matcha green tea
Ceremonial grade, organic. In Rise and Peak
Early research. In a placebo-controlled study of middle-aged and older adults, people taking matcha daily kept up their attention and amount of work during a mildly stressful task better than with caffeine alone. The study was run by a tea company's researchers.
Melatonin
0.5mg, plant-based. In Dusk only
Early research. Melatonin is a hormone your body makes in the evening. The US National Center for Complementary and Integrative Health says there is not enough strong evidence to recommend melatonin for long-term sleep problems, and that its safety in pregnancy, breastfeeding and children has not been well studied. Dusk uses a low 0.5mg dose and is for adults only.
The original maker's own study, read honestly
What the original maker's 60-day survey did, and did not, show
In 2024 the shots' original maker surveyed 82 healthy adults who had never used the product before. They answered five standard questionnaires (stress, anxiety, attention, fatigue and work performance) before starting, and again after 30 and 60 days of daily use. Every answer was self-reported. There was no placebo group, and the study was run privately by that maker. Read the full study (PDF).
-
Day 0
Starting point
Before the first shot (the study calls this Day 0), all 82 people filled in the questionnaires. The group's average stress score was 21.5 on a scale of 0 to 40, in the moderate range.
-
Day 30
Most of the change
After a month of one shot a day, the average stress score was 15.2 and the average fatigue score had fallen from 31.1 to 23.5 (on a scale of 10 to 50). For every measure, most of the change came in this first month.
-
Day 60
Smaller further shifts
At two months, average stress was 14.0 and fatigue 21.4. Attention and work performance scores rose by smaller amounts, and the work performance result only just passed the usual test for statistical significance.
What participants reported
Why these numbers are a starting point, not proof:
- No control group. Without a placebo group, the survey cannot separate the shot's effect from expectation, a new morning routine, or normal ups and downs over two months.
- Self-report only. All results came from questionnaires. No objective tests or blood markers were used.
- Run by the maker. The study was privately conducted and has not been independently reviewed or repeated.
- Short and small. 82 people over 60 days. It says nothing about longer use.
The survey also measured an anxiety questionnaire score. We leave it out of our headline numbers because these shots are not intended for anxiety. The study's own authors say a placebo-controlled trial is needed to confirm the results.
self-reported, survey
82% reported lower fatigue at Day 60 (67 of 82 people)
self-reported, survey
70% reported lower stress at Day 60 (57 of 82 people)

Honest science
What the science does not say (yet)
Being clear about the gaps matters as much as showing the studies. Here is what nobody has shown, for our products or for these ingredients.
- No supplement, including Lingo Leap, has been shown to treat speech delay, autism, ADHD or any developmental condition. If you are worried about your child's speech, talk to your paediatrician or a speech therapist.
- No one has tested Lingo Leap itself in a clinical trial. The evidence on this page is about its ingredients.
- Zeolite has not been studied in children, and there is no good evidence that it "detoxes" the body.
- Caffeine is not a substitute for sleep. A shot can make you feel more alert, but it does not repay lost rest.
- Most herb and nootropic studies are small, short and often funded by ingredient makers. Effects vary from person to person, and some people notice nothing.
- The shots list their herbs inside a blend, so the exact amount of each herb per shot is not published. The studies above used their own doses, which may differ.
- The original maker's 60-day survey had no placebo group, so it cannot prove the shots caused the changes people reported.
- Melatonin is not proven for long-term sleep problems, and supplements do not treat, cure or prevent any disease.

FAQ
Science questions
Is Lingo Leap suitable for my child's age?
Lingo Leap is for children aged 3 and over. Give one dropper (1ml) a day, on its own or mixed into a drink. If your child has a health condition or takes any medicine, check with your paediatrician before starting.
Can my child take Lingo Leap with other vitamins?
Often yes, but add up the totals. Many children's multivitamins and syrups already contain vitamin D and B12. Show your paediatrician the labels of everything your child takes so they can check the combined amounts.
Will Lingo Leap help my child start talking?
We cannot promise that, and no study shows it. Lingo Leap gives vitamin B12, vitamin D3 and zeolite, and we describe only their recognised nutrient roles. If you are concerned about your child's speech or development, please see your paediatrician or a speech therapist; early professional advice matters far more than any supplement.
How long until we notice anything?
Honestly, you may not notice anything you can see. Vitamins support normal body functions quietly, and they mainly make a difference when intake has been low. We do not give a timeline because no study of the product supports one.
Can teenagers use the MindMorn shots?
No. All four shots are for adults aged 18 and over. Rise and Peak contain caffeine, and Dusk contains melatonin, which has not been well studied in young people.
Can I have Peak and still drink tea or coffee?
Count it all together. Peak has 165mg of caffeine. European guidance says healthy adults can have single doses up to 200mg and up to 400mg across the day; a cup of tea has roughly 30 to 50mg and a brewed cup of coffee roughly 95mg. Have no more than one shot a day and avoid Peak in the afternoon if you want to sleep well.
Is Dusk safe to take every night?
Dusk uses a low 0.5mg dose of melatonin and is made for healthy adults as part of a bedtime routine, one shot a night at most. Long-term effects of nightly melatonin have not been well studied. Do not take it if you are pregnant, breastfeeding or under 18, and speak to your doctor if you take other medicines or have ongoing sleep trouble.
Where do the claims on this page come from?
From the product labels, the makers' own published material (including the 60-day survey run by the shots' original maker, which we may share as an authorised reseller), and the published studies and official sources listed in the references. Every link was checked when this page was written. If you spot something that looks wrong, message us on WhatsApp and we will look into it.
