I'm pretty sure the "regulators" don't examine every molecule of atmosphere going in your lungs, nor every wild blueberry that gets eaten. If I walk out my house to the nearest farm and buy some chickens, I somehow don't need a "regulator" to bless the occasion. And yet, well-"regulated" iatrogenic deaths cause non-negligable mortality in USA [1]. You can compare the rates of poisoning yourself (dietary supplements vs regulated prescription drugs) as reported by the American Association of Poison Control Centers [2]. The rates of death due to contamination, or for other reasons, are not comparable.

This is meant to suggest you may wish to revise your risk analysis.
