It should be considered that:

*micronutrients cannot compensate for unhealthy lifestyles such as mainly living on junk food, smoking, or drinking; they are not “magic bullets”.

*micronutrients mainly show health benefits when they balance an existing deficiency

*the relationship between diet and chronic disease is very complex: it is almost certain that several factors have to vary simultaneously for a positive effect to be observed

*high doses do not necessarily mean high benefits.
