EPA (which stands for eicosapentaenoic acid) keeps our cells nourished, while DHA (docosahexaenoic acid) is most famous for the role it plays in the brain, where its used to form much of the structural material of our grey matter, from cell membranes to neurons
In fact, taking them as a pair is often more effective than taking either one alone
The third is duration and safety : short controlled studies in animals say almost nothing about what months or years of exposure would do in a human, which is precisely why the cycling section defaults to scheduled off periods rather than open-ended use
Loren Pickart and colleagues isolated a short peptide from human plasma that extended the lifespan of cultured liver cells. They identified its sequenceglycyl-histidyl-lysine (GHK)and discovered that when bound to copper ions, it formed GHK-Cu, a complex with strong biological activity in cell growth and tissue repair
