Fire Starter is Heart & Soil's supplement made from grass-fed bovine kidney fat, designed to support fat metabolism, appetite control, and nutrient absorption.

This organ supplement provides tissue-specific peptides and nutrients that may help with weight management goals when combined with proper diet and exercise.

The concept is based on the "like supports like" principle—consuming specific animal tissues provides targeted support for similar functions in your body. Kidney fat contains unique nutrients not found in muscle meat that support metabolic function.

Like all Heart & Soil products, it's sourced from 100% grass-fed, grass-finished cattle raised on regenerative farms, freeze-dried to preserve nutrients, and third-party tested.
