- Masking Details
- The powder supplements are being administered in a blinded manner. An individual who is separate from the rest of the research team will generate the allocation schedule and prepare the supplement packages so that participants, investigators, and outcome assessors are blinded. Statistical analysis will be blinded by coding of groups
