The synergistic effect is ____ with each combination, each time and each person.

• A. Different
• B. Similar
• C. Identical
• D. Constant

Answer: (A)

The idea here is that synergy isn’t a fixed amount. When two or more factors interact to produce a bigger effect, that extra boost depends on exactly which factors are combined, how much is used, and when they’re taken, as well as who is experiencing it. People differ in physiology—enzyme activity, metabolism, health, weight, age, and prior exposure—all of which influence how strongly the factors interact. Because these variables change from one person to another and from one situation to the next, the synergistic boost can vary: one combination might produce a larger effect in one person and a smaller one in another, or the timing and dose might alter the magnitude of the synergy. That’s why the statement fits best with “different.”
