Is Melatonin the "Next Vitamin D"? TOP Melatonin Tips for Optimal Health

Ben describes his protocol: he normally uses little to no melatonin at home, but when traveling across many time zones (e.g., to Australia), he takes Midozen’s ‘Sandman’ – a 300 mg melatonin product available in oral and suppository forms. He chooses the suppository for a slower, more sustained release through the night, which he believes may reduce receptor saturation. He feels he adjusts to the new time zone dramatically faster, and the post-dose grogginess vanishes as soon as he gets morning light into his eyes. He learned this approach from Dr. John Lance (Mitozen). Diana counters that we simply don’t have long-term data on triple-digit milligram doses, and that physiologic doses (repleting what is lost with age) have a much larger safety evidence base. She acknowledges short-term use as a possible jet-lag hack but warns about receptor downregulation with prolonged high dosing.

Diana explains that kids produce the highest levels of pineal melatonin, which then rollercoasters downward. By 35 you have about a third of childhood levels, by 50 only 10%, and in the 60s near negligible production. Contrary to common fear, taking physiologic doses does not suppress endogenous production; at least four prospective studies found no negative feedback loop, and Russell Reiter confirmed no indication of suppression. She thinks of it as 'patching the potholes' — smoothing the age-related decline. Her personal choice of herbatonin (0.3 mg) suits her fast metabolizer status; her husband, a slow metabolizer, takes the same dose but 3 hours before bed. Her goal is not to supercharge sleep but to provide the cellular resilience melatonin normally affords.

Diana explains that CYP1A2, responsible for caffeine metabolism, also metabolizes melatonin. Therefore, your reaction to caffeine (e.g., being able to drink espresso before bed without issue like Ben) hints that you are a fast metabolizer and may need a higher dose or later timing to maintain sufficient blood levels through the night. For slow metabolizers (like her husband), taking the same dose 3 hours before bedtime allows for a more gradual onset and better alignment with the natural circadian curve. Genetics companies like 3x4 now test for melatonin receptor gene variants, which can cause melatonin to stick longer on receptors, potentially leading to circadian disruption and insulin changes. Diana herself has normal receptor activity, so her daily 0.3 mg at bedtime works.

Diana’s travel protocol combines chronobiotic principles with practical escalation. She attempts the ideal 15-minutes-per-night shift (hard to always achieve), then raises her herbatonin dose depending on distance. For cross-US travel she uses 3 mg; for Europe, up to 6 mg. This remains far below Ben’s 300 mg, but because herbatonin is 6–9× more functional, her effective antioxidant load is still substantial without reaching the unknown triple-digit territory. She also takes into account the oxidative damage of solar and ultraviolet radiation during flying, which melatonin can help buffer. This protocol fits her risk-benefit balance: proven safety of moderate doses even when temporarily elevated, plus the full suite of melatonin’s protective effects.

Diana is emphatic that artificial light at night is one of the most underappreciated societal health disruptors, affecting not just melatonin but the entire endocrine axis including the thyroid. She uses Philips Hue bulbs to shift her home lighting to red/purple/orange after dark. A study she mentions showed people with light-colored eyes had 17% greater suppression of melatonin from blue light than those with dark eyes. She has green eyes and wears blue light blockers religiously. Grocery stores, airports, and malls are the worst offenders, with blue ‘calming’ lights on planes being particularly misguided — red would be far better. Ben agrees and notes that society prioritizes GDP over sleep. This protocol is foundational: without it, any supplemental melatonin is fighting an uphill circadian battle.

Diana underscores that the pineal gland’s melatonin synthesis is a complex pathway requiring adequate substrate and cofactors. She warns against the popular myth that a handful of pistachios or cherries provides meaningful melatonin; her calculations show you’d need thousands. However, a tryptophan-rich diet (poultry, seeds, eggs) combined with B6 (chickpeas, fish, poultry) ensures the raw materials are present. For fast metabolizers like Ben, the rapid clearance can be counteracted not only by timing but also by formulation — taking melatonin with an omega-3 softgel can naturally slow absorption. She also notes that vitamin C may potentiate some of melatonin’s effects, though she emphasizes the omega-3 trick as under-utilized.

Diana references the work of Dr. Paulo Lissoni, who in the 1990s began giving advanced cancer patients 20–50 mg of melatonin along with chemotherapy. His publications showed that melatonin helped healthy cells stay intact while making chemotherapy more cytotoxic to cancer cells, and it reduced side effects. She explains that this makes sense through the lens of mitochondrial resilience: by fortifying mitochondria, melatonin raises the threshold for cellular damage in normal tissue while cancer cells, often with compromised metabolism, may not receive the same protective benefit. Additionally, melatonin’s ability to inhibit blood vessel growth that feeds tumors and to promote apoptosis is well documented. She notes that this use is distinct from sleep or aging protocols and must be tailored to the individual under clinical supervision.

Diana’s paper 'Is Melatonin the Next Vitamin D?' (Nutrients, 2022) argues that both molecules are 'circadian nutrients' — they align physiology with the 24-hour cycle via environmental inputs (light vs. dark). She emphasizes that melatonin, like vitamin D, is produced endogenously but declines dramatically after childhood, creating a rationale for supplementation that goes beyond sleep. The parallel extends to their myriad roles: both are anti-inflammatory, antioxidant, mitochondrial regulators, and immune modulators. Diana notes that while vitamin D synthesis requires sunlight (UVB), melatonin synthesis requires darkness; blue light at night disrupts it, just as lack of sun exposure disrupts vitamin D. This reframing could shift the public health conversation about melatonin from 'sleep aid' to foundational nutrient support.

Dr. Dunan Tan (colleague of Russell Reiter) demonstrated that melatonin not only directly scavenges radicals but also upregulates endogenous antioxidant enzymes like glutathione peroxidase and superoxide dismutase. Because it is amphiphilic (both water- and fat-soluble), it can enter cellular membranes, cytosol, and even the nucleus. Diana contrasts this with vitamin C, which works only in water-based compartments and handles just 1–2 radicals. Moreover, melatonin does not undergo redox cycling — a process where other antioxidants can turn pro-oxidant in high doses (e.g., beta-carotene in smokers). This makes melatonin arguably the safest long-term antioxidant. Diana points out that the metabolites of melatonin also retain antioxidant activity, giving it a sustained, multi-level protective effect that likely explains its benefits in metabolic disease, neurodegeneration, and aging.

Diana clarifies that while pineal melatonin is a classic endocrine effector, synchronizing peripheral clocks in response to darkness, gut melatonin operates in a completely different mode — autorine or paracrine. It is produced at every segment (lumen, mucosa, muscle layer) and appears to help maintain a healthy gut microbiome, regulate motility, and modulate local immunity (70% of immune cells reside in the gut). This might explain why some people notice changes in bowel habits when supplementing melatonin, and why jet lag disrupts gut function. Additionally, short-chain fatty acids from prebiotics stimulate serotonin release, which can then be converted to melatonin in the gut. Diana posits that the gut’s melatonin reservoir may provide a local protective barrier against pathogens and aid in tissue repair, though the full picture remains a mystery.

Diana, who is chief science officer at Symphony Natural Health, explains that herbatonin retains the plant matrix, which amplifies melatonin’s effects because cofactors like phytonutrients remain. In head-to-head testing, herbatonin was 6–9 times more potent in antioxidant capacity and anti-inflammatory activity, and quenched free radicals 100% more effectively in a skin cell model. Moreover, it naturally slows the release without requiring synthetic coatings, avoiding phthalates, parabens, and other endocrine-disrupting additives. Diana also warns that synthetic melatonin can contain contaminants like serotonin (found in 8 of 31 supplements in one study) and phthalomide derivatives, which could interfere with SSRIs and cause unexpected side effects. The plant-based form aligns with her philosophy of using nature-identical doses, filling the age-related gap without pharmacological overkill.

Diana mentions that she posted about this the morning of the interview: melatonin is being investigated for its role in glymphatic flux, acting as a 'shuttle' that aids the release of metabolic waste trapped in the brain during wakefulness. It also helps regulate aquaporins, the water channels responsible for fluid movement in the brain. This function aligns with the timing of peak pineal melatonin (2–4 a.m.) and deep slow-wave sleep, when glymphatic activity is highest. Ben mentions that his wearable (Ultrahuman ring) has just added a glymphatic drainage efficiency score based on sleep architecture, and he plans to test whether melatonin supplementation improves it. Diana sees this as a promising frontier for Alzheimer’s and Parkinson’s prevention, as melatonin’s neuroprotective, antioxidant, and anti-inflammatory actions converge on this nightly cleanup process.
