Meta analysis using the most serious outcome reported shows 24% [-24‑53%] lower risk, without reaching statistical significance. Results are worse for Randomized Controlled Trials and higher quality studies. Early treatment is more effective than late treatment. 3 studies from 3 independent teams in 2 countries show significant benefit.
1 RCT with 40 patients has not reported results (6 months late)1.
No treatment is 100% effective. Protocols combine safe and effective options with individual risk/benefit analysis and monitoring. Other treatments are more effective. Dietary sources may be preferred. The quality of non-prescription supplements varies widely2-4. All data and sources to reproduce this analysis are in the appendix.
