Uridine Side Effects & Safety
This content is for informational purposes only and does not constitute medical advice. Consult your healthcare provider before starting any supplement. Full disclaimer
Potential Side Effects
- Generally well-tolerated at recommended doses
- Mild digestive discomfort
- Rare: headache (may indicate need for choline co-supplementation)
- Rare: fatigue or brain fog at excessive doses
- Theoretically may feed cancer cell growth due to nucleotide role in cell proliferation — no clinical evidence of this at supplement doses
Drug & Supplement Interactions
- No significant drug interactions reported at supplemental doses
- Synergistic with DHA (omega-3) and choline sources (Alpha-GPC, CDP-Choline)
- Theoretical concern with nucleotide-targeting chemotherapy drugs — avoid during cancer treatment without oncologist approval
Maximum Dose
Do not exceed: 500mg UMP/day or 100mg TAU/day (limited long-term safety data at higher doses)
