Dietitian Mascha Davis explains how to get your vitamins and minerals from food instead of supplements.

Vitamins and minerals are the building blocks of good health, but the heavily processed foods that are so common in today’s modern diet are stripped of these nutrients. People are often left nutrient deficient despite meeting (or exceeding) their daily calorie needs.

Mascha Davis is an L.A.-based dietitian who is passionate about teaching others how to optimize their health through nutrition.

In this hack she highlights how lab-produced vitamin supplements are unreliable, with confusing dosage and interactions and loose regulation undermining their value. Instead, we should be getting our vitamins in the way nature intended: through a nutritious diet.
