Overview
Safety in plain terms
Generally safe near guideline doses; high-dose folic acid can mask B12 deficiency if B12 is not assessed.
Tolerability
Commonly reported effects
- Mild GI upset
- Sleep disruption (uncommon, person-specific)
Higher-risk contexts
Who should pause or get medical guidance first
- Ignoring B12 evaluation when neuropathy symptoms exist
- Ultra-high doses without medical reason
Polypharmacy
Interactions & cautions
- Methotrexate and some anti-folate drugs require medical coordination
Practical
Dose context (not a prescription)
Periconceptional dosing should follow medical guidance; do not hide B12 symptoms behind high folate alone.
