Obviously, the cost to sequence a genome depends on its size. The discussion below is focused on the human genome; keep in mind that a single 'representative' copy of the human genome is ~3 billion bases in size, whereas a given person's actual (diploid) genome is ~6 billion bases in size.
Alternatively, EPA has a more beneficial effect on lowering overall LDL (bad) cholesterol. In the cognitive domain, DHA appears to offer greater mental benefits. DHA has been suggested to be more effective in improving overall cognition and preventing cognitive decline in healthy older adults.
DHEA levels are lower in women who have lupus (an autoimmune disorder that affects the skin and organs). DHEA may boost immune function. Several trials report that DHEA may lack an effect on SLE disease activity, though there is some evidence supporting its use in addition to regular treatment.
