Detailed Clinical Evidence

Peer-reviewed research supporting each ingredient in Calmmind

N-Acetylcysteine (NAC)

How It Works

Modulates glutamatergic neurotransmission and increases glutathione production, reducing oxidative stress in the brain.

Key Clinical Studies

Hardan et al., 2012 - Biological Psychiatry

Participants: 29 children with autism

Results: 45% reduction in irritability and repetitive behaviours

Dosage: 900-2700mg daily (60mg/kg/day)

Safety Profile

Well-tolerated with mild GI effects most common. Extensive safety data from clinical trials.

Omega-3 EPA/DHA

How It Works

Supports dopamine transporter regulation and provides anti-inflammatory effects crucial for brain health.

Key Clinical Studies

Chang et al., 2018 - Neuropsychopharmacology

Participants: 534 participants (meta-analysis)

Results: Small but significant benefits (Cohen's d=0.38)

Dosage: 1000-3000mg EPA+DHA daily

Safety Profile

Excellent safety profile. EFSA upper limit of 5g/day EPA+DHA combined.

Magnesium Glycinate

How It Works

Essential for dopamine synthesis and NMDA receptor regulation. Deficiency documented in ADHD populations.

Key Clinical Studies

Effatpanah et al., 2019 - Meta-analysis

Results: Confirmed deficiency in ADHD populations

Dosage: 6mg/kg/day for children, 200-360mg for adults

Form: Glycinate provides superior absorption

Safety Profile

Well-tolerated. UK upper limit of 350mg/day supplemental magnesium.

Vitamin D3

How It Works

Supports neurotrophic factor production and reduces inflammation. Lower levels documented in ADHD populations.

Key Clinical Studies

Hemamy et al., 2021 - Combined Studies

Results: Supplementation combined with magnesium improved symptoms

Dosage: 1000-5000 IU daily based on deficiency status

Testing: 25(OH)D levels recommended

Safety Profile

UK guidelines: 400 IU/day standard, upper limit 4000 IU/day.

Zinc Picolinate

How It Works

Essential cofactor for dopamine transporter regulation and GABA modulation.

Key Clinical Studies

Bilici et al., 2004 - Clinical Trial

Participants: 400 children with ADHD

Results: 25% improvement in ADHD symptom scales when deficient

Dosage: 15-30mg elemental zinc daily

Form: Picolinate form for superior absorption

Safety Profile

UK upper limit: 40mg/day adults, 7-23mg children. Monitor copper levels with long-term use.

B-Complex Vitamins

How It Works

Essential cofactors for neurotransmitter synthesis including dopamine, serotonin, and GABA. Support energy metabolism and DNA synthesis in rapidly dividing brain cells.

Key Clinical Studies

Rucklidge et al., 2014 - British Journal of Psychiatry

Participants: 80 adults with ADHD

Results: Significant improvements in ADHD symptoms and mood regulation with B-complex supplementation

Duration: 8-week randomised controlled trial

Kaplan et al., 2004 - Journal of Child Psychology

Participants: Children with autism and ADHD

Results: Improved cognitive function and reduced hyperactivity

Key Finding: B6, B12, and folate particularly beneficial

Specific B-Vitamins in Calmmind

  • Vitamin B6 (Pyridoxal-5-Phosphate): 10mg - Active form for neurotransmitter synthesis
  • Vitamin B12 (Methylcobalamin): 100μg - Methylated form for optimal absorption
  • Folate (5-MTHF): 400μg - Active methylfolate form
  • Thiamine (B1): 25mg - Energy metabolism and nerve function
  • Riboflavin (B2): 25mg - Cellular energy production
  • Niacin (B3): 50mg - Brain energy metabolism
  • Biotin (B7): 150μg - Gene regulation and neural development
  • Pantothenic Acid (B5): 25mg - Neurotransmitter synthesis

Safety Profile

B-vitamins are water-soluble with excellent safety profiles. Dosages are within established safe upper limits. Active forms used for enhanced bioavailability and reduced side effects.

Our Research Standards

How we evaluate and select ingredients for Calmmind

Systematic Review

We systematically review all available peer-reviewed research, prioritising randomised controlled trials and meta-analyses.

Safety First

Every ingredient must demonstrate an excellent safety profile with documented use in children and adults.

Clinical Relevance

We only include ingredients with clinically meaningful effect sizes and real-world applicability.

Population Specific

Research must demonstrate benefits specifically in ADHD and autism populations, not just general cognitive enhancement.
