Frequently Asked Questions

• Feeling low on energy? Find out if you’re low in these key vitamins and minerals.

Empower yourself with insights into your diet so you can make informed decisions about your nutrition and performance.

• What are micronutrients and macronutrients?

  Micronutrients and macronutrients are found in the foods we eat, and our body needs to take in adequate amounts of both to function properly. Micronutrients consist of vitamins and minerals that optimize our body’s performance. Macronutrients include fats, carbohydrates and proteins that provide energy in the form of calories.    This micronutrient test can help identify if you’re deficient in certain vitamins and minerals, empowering you to make informed decisions on your health.
