Vitamin and mineral deficiencies commonly associated with the conditions this remedy may support.
An estimated 50% of adults consume below the EAR. Low magnesium is linked to insomnia, anxiety, migraines, muscle tension, and poor blood sugar regulation.
Common symptoms
- Muscle cramps or twitches
- Poor sleep
- Anxiety, irritability
- Headaches/migraines
- Constipation
Food sources
- Pumpkin seeds
- Dark leafy greens
- Almonds and cashews
- Dark chocolate (85%+)
- Black beans
- Avocado
Lab markers to discuss
- RBC magnesium (more sensitive than serum)
- Serum magnesium
Reference intake: 310–420 mg/day RDA depending on age and sex.
Supplementation notes: Glycinate for sleep/anxiety, citrate for constipation, threonate for cognitive/brain effects. Avoid magnesium oxide (poorly absorbed).
Why it matters here
Anxiety: Magnesium modulates the HPA axis and NMDA receptor activity; deficiency is linked to anxiety symptoms.
Autism Spectrum: Often combined with B6 in ASD support protocols.
Low vitamin D status is one of the most widespread deficiencies globally and has been linked to autoimmune disease activity (Hashimoto's, MS), mood disorders, recurrent infections, and poor skin barrier function.
Common symptoms
- Fatigue
- Low mood
- Frequent infections
- Bone or muscle aches
- Hair thinning
Food sources
- Fatty fish (salmon, sardines)
- Egg yolks
- Cod liver oil
- UV-exposed mushrooms
- Fortified dairy
Lab markers to discuss
- 25-hydroxyvitamin D (target 40–60 ng/mL per most functional ranges)
Reference intake: Adults 600–800 IU/day RDA; functional medicine often targets 2,000–5,000 IU/day with monitoring.
Supplementation notes: Take with a fat-containing meal. Pair with vitamin K2 (MK-7) when supplementing higher doses long-term.
Why it matters here
Autism Spectrum: Lower 25(OH)D levels associated with autism; supplementation trials show modest behavioral improvements.
Anxiety: Low vitamin D correlates with higher anxiety and depression scores.
Deficiency contributes to anxiety, low mood, PMS, and sleep disturbance.
Common symptoms
- Anxiety, irritability
- Poor sleep
- PMS symptoms
- Tingling in extremities
- Cracks at corners of mouth
Food sources
- Salmon, tuna
- Chicken
- Chickpeas
- Bananas
- Potatoes
- Sunflower seeds
Lab markers to discuss
- Plasma pyridoxal 5'-phosphate (PLP)
Reference intake: 1.3–1.7 mg/day; avoid >100 mg/day long-term (peripheral neuropathy risk).
Supplementation notes: P-5-P (active form) is preferred for those with poor conversion.
Why it matters here
Anxiety: Required for GABA and serotonin synthesis.
Low folate (or impaired conversion in MTHFR variants) is implicated in depression, anxiety, autism spectrum biology, and pregnancy complications.
Common symptoms
- Fatigue
- Low mood
- Brain fog
- Mouth ulcers
- Megaloblastic anemia
Food sources
- Leafy greens (spinach, romaine)
- Lentils and beans
- Asparagus
- Avocado
- Beef liver
Lab markers to discuss
- Serum folate
- RBC folate (better marker)
- Homocysteine
Reference intake: 400 mcg DFE/day; 600 mcg pregnancy.
Supplementation notes: Methylfolate (5-MTHF) is preferred over folic acid, especially with MTHFR C677T/A1298C variants.
Why it matters here
Autism Spectrum: Folate metabolism abnormalities (cerebral folate deficiency) found in subsets of ASD.
Deficiency is common in vegetarians/vegans, older adults, and those on PPIs or metformin. Strongly implicated in neurological symptoms (MS-like presentations), fatigue, anxiety, and cognitive decline.
Common symptoms
- Fatigue
- Tingling/numbness in hands or feet
- Brain fog
- Mood changes
- Glossitis (sore tongue)
Food sources
- Beef and lamb liver
- Clams and oysters
- Sardines
- Eggs
- Nutritional yeast (fortified)
Lab markers to discuss
- Serum B12 (>500 pg/mL functional)
- Methylmalonic acid (MMA)
- Homocysteine
Reference intake: 2.4 mcg/day RDA; therapeutic 1,000 mcg/day sublingual methylcobalamin is common.
Supplementation notes: Prefer methylcobalamin or hydroxocobalamin over cyanocobalamin, especially with MTHFR variants.
Why it matters here
Anxiety: Low B12 contributes to mood and anxiety symptoms.
Autism Spectrum: Methyl-B12 trials show improvement in some children with ASD.
Low EPA/DHA status correlates with depression, anxiety, dry skin, joint pain, and autoimmune flare risk.
Common symptoms
- Dry skin or eczema
- Joint stiffness
- Low mood
- Dry eyes
- Poor concentration
Food sources
- Wild salmon
- Sardines, anchovies, mackerel
- Cod liver oil
- Algae oil (vegan)
- Walnuts and flax (ALA only)
Lab markers to discuss
- Omega-3 Index (target 8–12% of RBC membrane fatty acids)
Reference intake: 250–500 mg combined EPA+DHA/day baseline; 1–3 g/day therapeutic.
Supplementation notes: Choose IFOS-certified or molecularly distilled fish oils to minimize heavy-metal exposure.
Why it matters here
Autism Spectrum: Some benefit on hyperactivity and stereotypy in ASD studies.
Anxiety: EPA-dominant omega-3s show benefit in anxiety in meta-analyses.
