HelloPharmacist Scorecard of Calm Support by GaiaKids

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 6 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

Calm Support contains 6 ingredients, 5 of which are active herbal extracts: organic skullcap aerial parts, organic passionflower flowering vine, organic lemon balm aerial parts, organic California poppy whole plant, and organic English lavender flower — plus organic vervain aerial parts, which we couldn't assess for interactions. These are delivered in a liquid form using vegetable glycerin and water as inactive ingredients (the base that carries the herbs).

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: calm and relaxation support for children.
  • We looked for evidence on: Anxiety, Insomnia, Adjustment disorders, Perioperative anxiety, Pre-procedural anxiety, Psychological well-being — and 4 related terms.
  • The strongest evidence on file: Lemon Balm is rated "Possibly Effective" for Stress (Natural Medicines).
  • Also on file: Passion Flower is rated "Possibly Effective" for Pre-procedural anxiety, Insomnia.
  • Also on file: California Poppy is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Insomnia.

The evidence picture is mixed across these herbs. Passionflower and lemon balm show the strongest data — both are rated Possibly Effective for insomnia and stress-related anxiety, with passionflower also supported for pre-procedural anxiety.

Lavender is rated Possibly Effective for dysmenorrhea (painful periods). Skullcap and California poppy, though widely used for similar purposes, don't have reliable evidence behind them yet — we rate both Insufficient Reliable Evidence to Rate for anxiety, insomnia, stress, and related concerns.

The data we hold doesn't establish effectiveness for any of these ingredients on other conditions listed.

The evidence, ingredient by ingredient Skullcap Passion Flower Lemon Balm California Poppy Lavender

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Skullcap, passionflower, lemon balm, and California poppy all carry the same pregnancy and lactation caution: avoid during pregnancy due to lack of safety data, and avoid while breastfeeding. Lemon balm's pregnancy guidance is slightly less strict — avoid unless your doctor advises otherwise.

Lavender's pregnancy and lactation data aren't on file. All five checked ingredients are generally well tolerated short-term, but side effects are possible.

The most common are sedation, dizziness, and digestive upset (nausea, constipation, or diarrhea). A small number of people report confusion or, rarely, allergic reactions.

Lavender can cause headache and gastrointestinal symptoms. One case report linked a very high dose of passionflower to severe nausea, vomiting, and heart rhythm changes, which resolved after stopping it.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 5 of the 5 matched ingredients can interact with medications — California Poppy, Lemon Balm, Lavender, Passion Flower, Skullcap.
  • The most serious interaction on file is rated Moderate.
  • For scale: 852 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you use Calm Support, check your medications against CNS depressants (sedatives, sleep aids, pain relievers, anxiety drugs, and some blood pressure medications) — all five herbal ingredients can add to their effects. If you take thyroid hormone replacement therapy, lemon balm may interfere with it.

Passionflower may theoretically reduce absorption of medications using the OATP transporter, or decrease effectiveness of drugs processed by the CYP3A4 enzyme — use the checker to confirm whether yours are affected.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is designed for kids seeking calming support, built from herbs with some evidence for stress and sleep. It's not for you if you take sedatives, sleep aids, or other CNS depressants — the combination could be too strong.

If you take thyroid hormone replacement, check with us first because lemon balm might interfere. Talk to your pharmacist or doctor before starting, especially if you're pregnant, breastfeeding, or taking any medications.

For each ingredient in Calm Support with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

organic Passionflower flowering vine extract3 drug types · 838 drugs

Cns Depressants

Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Research in animals and humans shows that passion flower has sedative effects which can be additive when used with sedative medications like lorazepam.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer.

Likelihood Possible Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
In vitro research shows that the passion flower constituents apigenin and vitexin inhibit OATP2B1 and OATP1A2. This inhibition may be dose-dependent. One specific high-flavonoid passion flower extract (Valverde) seems to inhibit OATP2B1 and OATP1A2, while another extract with a lower flavonoid concentration (Arkocaps) shows less potent inhibition. OATPs are responsible for the uptake of drugs and other compounds into the body; however, the specific activities of OATP2B1 and OATP1A2 are not well characterized.

Likelihood Possible Evidence D
organic Passionflower flowering vine extract full monograph & interactions

organic Lemon Balm aerial parts extract2 drug types · 264 drugs

Cns Depressants

Theoretically, concomitant use of lemon balm might have additive effects with CNS depressant drugs.
Lemon balm seems to have CNS depressant activity in animals and in humans.

Likelihood Possible Evidence B
Thyroid Hormone

Theoretically, lemon balm might interfere with thyroid hormone replacement therapy.
In vitro, constituents of lemon balm extract bind to thyroid stimulating hormone (TSH), preventing TSH receptor-binding and leading to the inhibition of TSH-stimulated adenylate cyclase activity. In animals, lemon balm extract has been shown to decrease levels of circulating TSH and inhibit thyroid secretion.

Likelihood Possible Evidence D

organic Skullcap aerial parts extract1 drug type · 248 drugs

Cns Depressants

Theoretically, skullcap can have additive effects when used with other CNS depressants.
Animal and clinical research suggests that skullcap can cause sedation and cognitive impairment.

Likelihood Possible Evidence D

organic California Poppy whole plant extract1 drug type · 248 drugs

Cns Depressants

Theoretically, taking California poppy with drugs with sedative effects may increase the risk of sedative effects.
Laboratory research shows that California poppy has sedative effects.

Likelihood Possible Evidence D

organic English Lavender flower extract1 drug type · 248 drugs

Cns Depressants

Theoretically, lavender might potentiate the therapeutic effects and adverse effects of CNS depressants.
Laboratory research suggests that lavender has sedative effects. However, clinical studies in patients taking oral lavender oil (Silexan) 160 mg for 10 weeks or taking lavender flower powder 1 gram daily for 2 months have not reported side effects of drowsiness, sedation, or sleepiness. There is still some concern that higher doses or different preparations of lavender might have additive effects with CNS depressant medications.

Calm Support by GaiaKids: Common Questions

Does Calm Support by GaiaKids interact with any medications?
Yes. Based on its ingredients, Calm Support has a known interaction with 851 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Calm Support contains 6 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is Calm Support safe to use while I'm pregnant or breastfeeding?
No, the data advises against it. Skullcap, passionflower, lemon balm, and California poppy should all be avoided during pregnancy and breastfeeding because there isn't enough safety information. Lemon balm is slightly less strict in pregnancy — you could take it with your doctor's approval — but data on lavender and vervain during pregnancy or lactation aren't on file. Talk to your doctor or pharmacist before using this product if you're pregnant or nursing.
Will this make my child drowsy?
Sedation is one of the most common side effects reported with these herbs. Dizziness and confusion can also happen. How much your child feels these effects depends on the dose and which ingredients affect them most, so start by talking to your pharmacist about what to expect and watch for.
Does Calm Support actually work for anxiety and sleep?
Passionflower and lemon balm have decent evidence — both are rated Possibly Effective for insomnia and stress-related anxiety, with passionflower also supported for pre-procedural anxiety. Skullcap and California poppy are used for similar reasons but don't have reliable evidence yet. Lavender's evidence is limited to painful periods. The ingredients in this blend may help, but results vary by person.
What are the common side effects?
Sedation, dizziness, and digestive upset (nausea, constipation, or diarrhea) are the most common. Headache, confusion, and mild allergic reactions are reported less often. A small number of people report digestive disturbances — around 9% in one study of skullcap alone.
Can my child take this with their sleep medication or anxiety medicine?
Probably not without checking first. All five herbal ingredients in this product can add to the effects of sedatives and other CNS depressants — prescription sleep aids, anti-anxiety drugs, and some pain or seizure medications. The combination could be too strong. Use the medication checker on this page or talk to your pharmacist before adding this product.
What does each ingredient do?
Skullcap, passionflower, lemon balm, California poppy, and lavender are all traditional calming herbs — they're included because they're thought to reduce anxiety and support sleep. Vervain is also a traditional calming herb, but we have no interaction data on file for it. None of these have been proven to work for anxiety or insomnia in kids specifically, though some have evidence in adults.
