Even a highly purified peptide can produce inconsistent experimental results if it is improperly reconstituted, contaminated during handling, or stored outside recommended conditions
Consequently, oral supplements can be highly variable in how much B12 they actually deliver to the cells, particularly in older adults
However, injections are more effective for people who cannot absorb B12 through their stomach
This synthetic peptide, derived from a natural protein in the stomach, has been studied for its potential in tissue repair, inflammation control, and cell protection
They are often most effective when used to complement a well-designed plan that includes nutritional support, movement, and ongoing accountability
