Below is general information about the safety of the known ingredients contained in the product Brain Calm. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts commonly found in foods.
POSSIBLY SAFE ...when used orally in medicinal amounts, short-term. GABA has been used with apparent safety in doses of 75 mg to 1.5 grams daily for up to one month in small clinical studies (19361,19363,19369,110134,110135). There is insufficient reliable information available about the safety of GABA when used orally for longer than one month or when used sublingually or intravenously.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Glycine has been used safely at doses up to 6 grams daily for 4 weeks (106497) and doses up to 9 grams daily for 3 days (10250,10251,10252,92319). There is insufficient reliable information available about the safety of glycine when used topically.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Inositol has been used with apparent safety in doses up to 18 grams daily for up to 6 weeks or 6 grams daily for 10 weeks (2184,2185,2187,95089). Myo-inositol 4 grams daily has also been used with apparent safety for 6 months (95085). There is insufficient reliable information available about the safety of inositol when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately.
Inositol 80 mg/kg (maximum 2 grams) has been taken daily for up to 12 weeks in children aged 5-12 years (95092). ...when used enterally or intravenously and appropriately in premature infants for treating acute respiratory distress syndrome for up to 10 days (2191,2192,91546,91551).
CHILDREN: POSSIBLY UNSAFE
when used enterally or intravenously for extended durations in premature infants.
A large clinical study in infants born at less than 28 weeks' gestation found that myo-inositol 40 mg/kg, given intravenously and then enterally every 12 hours for up to 10 weeks, was associated with a small increased risk of death (98946). Long-term follow-up until 24 months corrected age confirms that the initial increase in mortality rate in the myo-inositol group remained stable; however, there was no difference in a composite outcome of death or survival with moderate or severe neurodevelopmental impairment, as well as no difference in the risk of retinopathy of prematurity, between those who received myo-inositol or control (108819).
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately, short-term.
Myo-inositol has been used with apparent safety in amounts up to 4000 mg daily during pregnancy (91548,95082,104688).
LACTATION:
Insufficient reliable information available; avoid using.
Breast milk is rich in endogenous inositol (2138); however, the effects of exogenously administered inositol are not known.
LIKELY SAFE ...when used orally as a flavoring in foods. The US Food and Drug Administration (FDA) lists passion flower as a permitted food flavoring additive, to be used in the minimum quantity necessary (91203).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Passion flower extract has been used with apparent safety at doses up to 800 mg daily for up to 8 weeks (88198,102866). A specific passion flower extract (Pasipay, Iran Darouk Pharmaceutical Company) has been safely used at a dose of 45 drops daily for up to one month (8007,95036). Also, a tea prepared by steeping 2 grams of the dried aerial parts of passion flower in 250 mL of boiling water for 10 minutes has been used nightly for 7 nights (17374). There is insufficient reliable information available about the safety of passion flower when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
A specific passion flower product (Pasipay, Iran Darouk Pharmaceutical Company) has been used safely in children aged 6-13 years at a dose of 0.04 mg/ kg daily for 8 weeks (88197).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Some case reports suggest that passion flower use during the first and second trimesters of pregnancy may be associated with an increased risk for premature rupture of membranes and meconium aspiration syndrome; however, causality has not been confirmed (97279). The alkaloids harman and harmaline, which are sometimes found in passion flower, have been reported to have uterine stimulant activity (4,11020,95037). It is not known whether these constituents are present in sufficient quantities to have an effect.

Below is general information about the interactions of the known ingredients contained in the product Brain Calm. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, taking GABA with antihypertensive drugs might increase the risk of hypotension.
Details
Some clinical research shows that GABA can decrease blood pressure in patients with hypertension (19367).
|
Theoretically, GABA might have additive sedative effects when used in conjunction with CNS depressants. However, it is unclear if this concern is clinically relevant.
Details
Endogenous GABA has well-established relaxant effects (51152) and GABA(A) receptors have an established physiological role in sleep (51143). However, the effects of GABA supplements are unclear, as it is unknown whether exogenous GABA crosses the blood-brain barrier (51120,51153,90570). Although there have been limited reports of drowsiness or tiredness with GABA supplements (5115,19364), these effects have not been widely reported in clinical studies. Additionally, intravenous GABA 0.1-1 mg/kg has been shown to induce anxiety in a dose-dependent manner (5116).
|
Theoretically, glycine might decrease the effectiveness of clozapine.
Details
One small clinical study in patients with schizophrenia shows that adding glycine to clozapine therapy worsens symptoms of schizophrenia when compared with clozapine alone (10253). The mechanism of this interaction is unclear.
|
Theoretically, taking inositol with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Concomitant use of passion flower with sedative drugs might cause additive effects and side effects.
Details
|
Theoretically, passion flower might decrease the effects of CYP3A4 substrates.
Details
In vitro research suggests that passion flower can induce CYP3A4 enzymes, albeit to a much lower degree than rifampin, a known CYP3A4 inducer (110704).
|
Theoretically, passion flower might reduce the bioavailability of OATP2B1 and OATP1A2 substrates.
Details
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 (105095). 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.

Below is general information about the adverse effects of the known ingredients contained in the product Brain Calm. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, GABA seems to be generally well tolerated.
Sublingually, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Drowsiness, gastric upset, minor throat burning, muscle weakness, and nausea.
Cardiovascular ...Intravenously, GABA can cause dose-related increases in blood pressure and pulse (5116).
Gastrointestinal ...Orally, minor throat burning has been associated with GABA in one study (5115). In another study in which GABA was administered with phosphatidylserine, one patient experienced severe gastric distress, two patients reported moderate nausea, and one reported constipation (19364). Children with cerebral palsy taking GABA experienced nausea and decreased appetite (19362).
Genitourinary ...In one study, one patient treated with oral GABA and phosphatidylserine reported transient amenorrhea (19364).
Musculoskeletal ...Orally, minor adverse effects associated with GABA included muscle weakness (5115).
Neurologic/CNS ...Orally, GABA may cause drowsiness or tiredness (5115,19364). Four children with cerebral palsy taking GABA had convulsions, and an unspecified number experienced motor restlessness. However, causality of these adverse effects was not clear, and the dose of GABA was not specified (19362). Intravenously, GABA 50 mg has been associated with a "lack of alertness" in healthy female volunteers (51159).
Psychiatric ...Intravenously, GABA 0. 1-1.0 mg/kg has been shown to induce anxiety, dysphoria, and mood disturbances in a dose-dependent manner (5116).
Other ...In one study, patients taking GABA experienced a slight warming of the body (19370).
General ...Orally and topically, glycine seems to be well tolerated.
Gastrointestinal ...Soft stools, nausea, vomiting, and upper gastrointestinal (GI) tract discomfort have occurred rarely with oral use of glycine. These symptoms resolve rapidly with discontinuation of glycine (10252,11320,92319). Dry mouth has also been reported but any association to glycine is unclear (92321).
Neurologic/CNS ...Mild sedation has occurred rarely with oral use of glycine. Symptoms resolve rapidly with discontinuation of glycine (10252,11320,92321). Irritability, insomnia, fatigue, memory impairment, headache, and sensory impairment have been reported, but any association with glycine is unclear (92321).
General
...Orally and intravenously, inositol seems to be well tolerated.
Topically, no adverse effects have been reported, although a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, gas, and nausea.
Gastrointestinal ...Orally, inositol may cause nausea, diarrhea, gas, and gastrointestinal discomfort (10387,11972,91547,91549,95089,95090,95092).
Immunologic ...Orally, inositol in combination with omega-3 fatty acids has been associated with reports of cold and allergy symptoms in children in clinical research (95092).
Musculoskeletal ...Orally, inositol in combination with omega-3 fatty acids has been associated with reports of tics and other musculoskeletal side effects in children in clinical research (95092).
Neurologic/CNS ...Orally, inositol may cause dizziness, tiredness, insomnia, agitation, and headache (10387,11972,95089,95092). In combination with omega-3 fatty acids, inositol has been associated with reports of feelings of thirst in children in clinical research (95092).
Psychiatric ...In one case report, a 36-year-old male with adequately controlled bipolar disorder was hospitalized with symptoms of mania after consuming several cans of an energy drink containing inositol, caffeine, taurine, and other ingredients (Red Bull Energy Drink) over a period of 4 days (14302). It is not known if this is related to inositol, caffeine, taurine, a different ingredient, or a combination of the ingredients.
General
...Orally, passion flower is well tolerated.
Most Common Adverse Effects:
Orally: Confusion, dizziness, hypersensitivity, and sedation.
Cardiovascular ...There is a case report involving a 34-year-old female who was hospitalized with severe nausea, vomiting, drowsiness, prolonged QT interval, and episodes of nonsustained ventricular tachycardia following use of passion flower extract tablets (Sedacalm, Bioplus Healthcare), 1500 mg on day 1 and 2000 mg on day 2 to relieve stress. All symptoms resolved within one week after passion flower was discontinued (6251).
Genitourinary ...The alkaloids harman and harmaline, which are sometimes found in small amounts in passion flower, have been reported to have uterine stimulant activity (4,11020,95037).
Hematologic ...Orally, passion flower has been reported to cause epistaxis in one clinical trial (95038). Vasculitis has also been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
Hepatic ...There is debate about whether passion flower contains cyanogenic glycosides. Several related Passiflora species do contain these constituents (3), including Passiflora edulis, which is associated with liver and pancreatic toxicity (7).
Immunologic
...An idiosyncratic hypersensitivity reaction characterized by urticaria and cutaneous vasculitis has been reported in a 77-year-old male with rheumatoid arthritis after taking a specific combination product that included passion flower extract (Naturest) (68308).
It is unclear if these effects were caused by passion flower or other ingredients.
In clinical trials, passion flower has been reported to cause allergy symptoms including sinus irritation; however, the frequency of these events was statistically nonsignificant when compared to treatment with midazolam 15 mg (95038).
Musculoskeletal ...Orally, passion flower has been reported to cause muscle relaxation in a clinical trial (95038).
Neurologic/CNS ...Orally, sedation, dizziness, ataxia, and confusion have been reported in clinical trials. However, these events generally do not necessitate discontinuation (8007,15391,15392,95036,95038). Altered consciousness has been reported with use of a specific herbal product (Relaxir) produced mainly from the fruits of passion flower (6).
