Vitamins & Minerals: The Complete Guide for Fitness Enthusiasts (2026)

Introduction

The micronutrients in this formula provide all of the following benefits: They help your body utilize food for energy, promote muscle recovery and growth, help strengthen bones, boost immunity, and improve performance.

Vitamins and minerals are needed in lower quantities than macronutrients, but deficiencies can cause a decrease in strength, energy, and recovery.

What Are Vitamins?

Vitamins are organic compounds required for normal growth, metabolism, and health. The body does not synthesize sufficient quantities of most vitamins, and these must therefore be obtained from food.

• Vitamin B5

• Vitamin B6

• Vitamin B7 (Biotin)
