Ingredient research and its limits
The finished Healvo formula has not been tested in these trials. Ingredient studies do not establish its effects, an individual result or a time to benefit. Amounts shown are manufacturing specifications; follow the final product label.
Source notes updated .
| Ingredient | Healvo amount per serving | Studied dose and preparation | Participants and duration | Findings and limits |
|---|---|---|---|---|
| Reishi fruiting body extract | Healvo amount per serving1,000 mgManufacturing specification | Evidence gap in this review No matching human trial is cited here for this Reishi preparation and serving amount for a daily calm, sleep or foundation benefit. This is a limit of the evidence presented, not a claim that no studies exist. | ||
| Glycine | Healvo amount per serving3,000 mgManufacturing specification | Studied dose and preparationBannai et al., 2012 3 g before bed Glycine taken separately from the other ZenRest ingredients | Participants and duration 7 healthy men analyzed after 2 of 9 recruits were excluded; experimentally restricted sleep 3 consecutive nights in a crossover experiment | Findings and limits Daytime fatigue was lower on day 1, not day 3; psychomotor vigilance improved. Limit: A very small, short study in sleep-restricted men does not establish chronic insomnia treatment or a result from ZenRest. Sharing a numerical dose is not finished-product evidence. |
| Magnesium (as magnesium bisglycinate) | Healvo amount per serving250 mg elementalManufacturing specification | Studied dose and preparationSchuster et al., 2025 250 mg elemental magnesium/day Magnesium bisglycinate capsules also providing 1,523 mg glycine/day from the chelate | Participants and duration 155 adults aged 18–65 reporting poor sleep 4 weeks | Findings and limits Self-reported Insomnia Severity Index improved slightly relative to placebo (small effect, d=0.2). Limit: Our elemental-magnesium amount matches numerically, but this trial also supplied glycine through its chelate and did not test our six-ingredient powder. It does not guarantee better sleep. |
| Lemon balm extract (leaf) | Healvo amount per serving600 mgManufacturing specification | Studied dose and preparationKennedy et al., 2004 Single 300 mg and 600 mg doses on separate days Standardized Melissa officinalis extract | Participants and duration 18 healthy volunteers under a laboratory stress task Acute crossover: assessed 1 hour after dosing, with 7-day washouts | Findings and limits The 600 mg dose increased self-rated calmness and reduced alertness during the laboratory task. Limit: Our extract is not confirmed equivalent. A single laboratory stress experiment does not establish chronic stress relief, insomnia treatment or a result from this formula. |
| L-theanine | Healvo amount per serving200 mgManufacturing specification | Studied dose and preparationHidese et al., 2019 200 mg/day before sleep Suntheanine L-theanine tablets | Participants and duration 30 adults aged 20–69 without major psychiatric illness 4 weeks per condition in a crossover trial | Findings and limits Some self-reported sleep subscales improved relative to placebo. Broader stress-score improvements were mainly within the L-theanine condition. Limit: This small study does not establish a product-specific effect or onset. Our material is not confirmed as the studied branded preparation; taking it in a blend or at another time is a different intervention. |
| Magnolia bark extract | Healvo amount per serving200 mgManufacturing specification | Evidence gap in this review No matching human trial is cited here for 200 mg of this magnolia extract alone for sleep; findings from combination products cannot be assigned to magnolia alone. This is a limit of the evidence presented, not a claim that no studies exist. | ||
