Melatonin has long been touted as a safe, reliable — and natural — way to help kids get to sleep. But is it doing more harm than good? 

Synthetic versions of the naturally occurring hormone — often in the form of drops or gummies for kids — promise an easier bedtime. Nearly 46% of parents reported giving the supplement to a child younger than 13 to help them sleep, according to an American Academy of Sleep Medicine poll.

But a recent study linking chronic melatonin use to heart failure has parents concerned. And another study found a “wide range” in concentrations of melatonin in products. ”Because melatonin is a dietary supplement and not a drug, it’s not FDA-regulated,”  Dr. David Fagan, vice chair for pediatric ambulatory administration at Cohen Children’s Medical Center Northwell Health, says. “The actual melatonin content can vary really widely.”

Fagan spoke to PEOPLE about who might be a candidate for melatonin and what to watch out for, while emphasizing that kids shouldn’t be given melatonin without consulting their pediatricians first.

Is melatonin recommended for children?

“The American Academy of Pediatrics does not recommend melatonin use as a first-line aid to help children get to sleep and to stay asleep,” Fagan tells PEOPLE. Instead, he said, before reaching for supplements, doctors recommend “behavioral sleep strategies.” These include: consistent bedtime, limiting screen time before bedtime, and having a sleep-friendly environment — like a quiet, dark space, perhaps with blackout curtains — before using a supplement like melatonin.

He shared that for children with neurodevelopmental disorders like ADHD or autism, “short-term use of melatonin” does appear to be safe, as children with ADHD, for example, are often on a stimulant medication and melatonin may help regulate their sleep cycles. “But again, the American Academy of Pediatrics and the American Academy of Sleep Medicine do not recommend melatonin as a first-line solution for sleep problems.”

Once approved by a pediatrician, what does safe melatonin use look like?

“We would want to start with the lowest possible dose,” Fagan says, which is usually 1 mg. “And we would never give it to a child under the age of 2.”  He also tells PEOPLE that melatonin should not be used every night, and urged parents to speak to their pediatrician about how to give their child breaks from the supplement. 

What negative side effects should parents should watch out for?

Children can take too much of it, Fagan tells PEOPLE. It can cause “morning grogginess, you could have headaches, mood swings.” The supplement can also cause “really very, very vivid, vibrant dreams.” 

If a child has a seizure disorder and is taking an anti-epileptic drug, the interaction of melatonin and the medication could make that child “more likely to have a seizure,” according to Fagan. It can also increase blood pressure, which is why parents must contact their pediatrician before giving their child melatonin: “Every child is different, but parents should, with their pediatrician, review other medications that the child is on for any potential interactions.”

Is magnesium a safe alternative to melatonin?

“The evidence with magnesium is really very limited and and weak,” Dr. Fagan tells PEOPLE, noting that while it can play a role in relaxation, “there is no strong clinical data showing it improves sleep in healthy children.”

What is the biggest misconception about melatonin?

The biggest misconception about melatonin, he says, is that “it’s a cure-all for sleep problems.”

If a family wants to start their child on melatonin, first, he recommends trying the behavioral sleep strategies listed above. “If they’ve done all of that and exhausted all of that, then we would talk about melatonin.”

Washington, DC—The Council for Responsible Nutrition (CRN) announced the publication of new and updated chapters in its Vitamin & Mineral Safety, Fourth Edition (VMS4) series. The content expands this comprehensive, science-based resource on nutrient safety. The latest updates include:

A new safety evaluation for choline and citicoline.

These are essential nutrients for brain and liver health. Based on data from more than 20 human clinical trials, and consistent with prior evaluations by the Institute of Medicine (IOM), CRN reaffirmed IOM’s UL of 3,500 mg per day for choline and derived a new supplemental UL of 2,000 mg per day for citicoline. This new content also reviews recent observational studies exploring possible links between choline intake and cardiovascular disease (CVD) outcomes; CRN determined that a clear relationship between dietary choline intake and CVD outcomes cannot be established from the current body of evidence. “This new chapter closes a long-standing gap in nutrient safety guidance,” said Andrea Wong, Ph.D., Senior Vice President, Scientific & Regulatory Affairs, CRN. “Choline and citicoline play vital roles in cognition, liver health, and metabolism—and the evidence confirms their safety when consumed at reasonable supplemental levels.”

A new chapter on lutein, zeaxanthin, and meso-zeaxanthin.

These carotenoids are associated with vision and eye health. Building upon CRN’s earlier risk assessment for lutein (Shao and Hathcock, 2006), the updated review draws from approximately 75 human clinical trials and global evaluations by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA). CRN reported that no serious adverse effects were identified across studies, even at doses far exceeding typical dietary intakes. Based on the available data, CRN maintained the Highest Observed Intake (HOI) of 22 mg per day for lutein previously established in 2006, and established an HOI of 26 mg per day for zeaxanthin and 17 mg per day for meso-zeaxanthin. “This chapter offers the most updated picture of the clinical safety of lutein, zeaxanthin, and meso-zeaxanthin,” said Dr. Wong. “It affirms these bioactives’ strong safety record and their important contribution to visual health.”

An updated folate chapter.

This new content reaffirms the existing UL of 1 mg per day for folic acid. This chapter also includes a new section on methylfolate (5-MTHF)—the active form increasingly featured in supplements and fortified foods.The updated review synthesizes the latest findings on the safety, metabolism, and bioavailability of methylfolate, establishing a UL of 1.5 mg per day. “Our updated folate chapter provides clarity for today’s market,” said Dr. Wong. “By distinguishing folic acid and methylfolate, CRN is helping ensure safety standards keep pace with innovation.”

An updated Vitamin K2 (menaquinone-7, MK-7) chapter.

The evaluation established a supplemental HOI level of 375 µg/day for adults. Previous editions of CRN’s Vitamin & Mineral Safety derived a single UL value for vitamin K, encompassing vitamin K1 and vitamin K2. Given the growing consumer interest and use of vitamin K2 supplements worldwide, a separate assessment was conducted for vitamin K2, specifically MK-7. CRN noted that this offers essential new guidance for manufacturers, regulators, and health practitioners seeking evidence-based recommendations for this nutrient, which is widely recognized for its role in supporting bone and cardiovascular health. “CRN’s updated MK-7 chapter reflects our commitment to providing rigorous, transparent safety evaluations grounded in the totality of evidence,” said Dr. Wong. “Establishing a HOI for Vitamin K2 (MK-7) represents a major step forward for scientific understanding and responsible product development across the dietary supplement category.”

The new content is accessible at www.crnusa.org/resources/vitamin-mineral-safety. Additional nutrient reviews are scheduled for release throughout 2026.

Drivers

Growing consumer shift toward preventive and personalized nutrition

The rise of preventive healthcare and personalized nutrition is expected to strengthen demand for at-home micronutrient testing as consumers increasingly monitor deficiencies that influence energy, immunity, cognitive performance, and metabolic health. A growing volume of clinical literature highlights the widespread prevalence of micronutrient gaps, such as vitamin D insufficiency affecting more than one-third of adults in several countries, which encourages individuals to seek convenient and affordable testing options without visiting a clinic.

The shift toward virtual care ecosystems further accelerate home-based testing adoption, as digital platforms integrate micronutrient reports with supplement recommendations, teleconsultations, and lifestyle guidance. Companies offering finger-prick vitamin D, B12, iron, or magnesium tests have expanded online distribution, enabling rapid purchase, doorstep delivery, and seamless digital result interpretation.

Examples include platforms providing personalized dashboards that show trends over time, correlating diet patterns with test outcomes. Consumers engaged in fitness programs, weight-loss regimens, or immunity-focused lifestyles increasingly prefer home tests to understand nutrient gaps that influence performance or fatigue levels.

With rising awareness through health campaigns and educational content from healthcare providers, the driver gains momentum as more individuals adopt proactive monitoring rather than waiting for clinical symptoms to emerge. This structural consumer behavior shift continues to anchor growth.

Restraints

Limited accuracy compared to laboratory-based diagnostics

Despite rising demand, accuracy challenges associated with home-based micronutrient tests act as a restraint, as results may vary due to collection inconsistencies, environmental exposure, or limitations of finger-prick sampling for certain analytes.

For example, blood spot tests may not perfectly reflect serum concentrations for markers such as zinc or magnesium because micronutrient distribution differs between plasma and whole-blood compartments. This discrepancy leads some clinicians to caution against using home kits for complex deficiency assessment, especially for patients with underlying conditions or those requiring high-precision monitoring.

Additionally, improper collection techniques, such as insufficient blood volume or contamination during sample drying, can lead to errors or invalid results. Users without medical training may find it difficult to follow exact procedural steps, increasing the probability of variability compared to standardized phlebotomy in diagnostic labs. Regulatory considerations also restrict certain biomarkers from being offered outside professional settings, limiting the scope of nutrients measurable at home.

For example, some markets allow only specific vitamin assays through direct-to-consumer channels, while others require physician involvement. These combined concerns reduce confidence among healthcare professionals, potentially slowing adoption among populations that rely on clinically validated results. The restraint persists as long as testing accuracy remains uneven across nutrient categories.

Opportunities

Integration of AI-enabled personalized nutrition ecosystems

A major opportunity emerges from integrating at-home micronutrient testing into AI-driven personalized nutrition platforms that combine biomarker data, dietary habits, genomic markers, and lifestyle inputs into tailored recommendations. As consumers increasingly adopt digital health tools, companies are developing algorithms that correlate micronutrient levels with sleep quality, activity performance, stress responses, and dietary intake patterns.

For example, vitamin D trends can be linked with sunlight exposure data from wearable devices, while iron or B12 levels may be analyzed alongside menstrual cycle tracking or diet logs to predict depletion risks. This integrated ecosystem creates recurring revenue models through subscription-based testing, supplement delivery programs, and personalized meal planning applications.

Startups are exploring AI-generated supplement formulation systems that adjust dosage recommendations based on follow-up test results, enabling dynamic correction of deficiencies. Partnerships between diagnostics firms, nutrition technology companies, and wellness platforms present opportunities to expand market reach across fitness, corporate wellness, and preventive health services.

As governments and health organizations emphasize chronic disease prevention through nutrition, digital micronutrient monitoring platforms align with population-level health goals. The rise of remote care and tele-nutrition services strengthens this opportunity, allowing micronutrient testing to function as a foundational component of long-term health optimization.

Impact of Macroeconomic / Geopolitical Factors

Macroeconomic and geopolitical factors influence the At-Home Micronutrient Testing Market by shaping consumer spending, supply chain stability, and access to diagnostic materials. Periods of economic slowdown typically shift household spending toward essential healthcare, which benefits at-home testing because it offers a lower-cost alternative to clinical diagnostics.

However, inflation-driven increases in raw material and logistics costs can raise kit prices, affecting affordability in price-sensitive markets. Geopolitical tensions also impact the sourcing of assay components, microfluidic cartridges, reagents, and lateral-flow materials, which are often manufactured across multiple countries. Disruptions in global trade routes or restrictions on chemical exports may slow production timelines and limit inventory availability for online and retail channels.

Public health policy changes in response to geopolitical events further influence demand. For example, global energy and food supply uncertainties increase consumer awareness of immunity, fatigue, and nutritional well-being, contributing to higher self-monitoring behavior.

Shifts in labor markets, such as the rise of remote work, encourage more people to adopt home diagnostics rather than visiting clinics. At the same time, increased government scrutiny over cross-border data transfers and digital health privacy may affect how testing companies store and process user data.

Latest Trends

Rapid adoption of home-based finger-prick vitamin and mineral panels

A prominent trend in the market is the rapid adoption of home-based finger-prick testing panels that allow individuals to measure multiple vitamins and minerals in a single kit with minimal effort. These panels often include vitamin D, B12, folate, ferritin, magnesium, zinc, and other commonly deficient nutrients, offering a broader view of nutritional status than single-analyte tests.

Consumers increasingly prefer bundled panels because they provide deeper insight into health drivers such as fatigue, hair thinning, muscle performance, and immune resilience. The convenience of collecting a small blood sample at home and shipping it to certified laboratories aligns well with work-from-home lifestyles and the broader acceptance of telehealth services.

Companies expanding test portfolios frequently promote user-friendly sampling devices designed to reduce discomfort and improve sample accuracy, which enhances trust and repeat usage. In addition, the trend is reinforced by growing online health communities where individuals share experiences, compare deficiency patterns, and seek advice on restoring optimal nutrient levels.
