Compound Solutions is known through the sports nutrition industry for several versatile, proven, and effective ingredients, including the likes of Metabolyte, Amino9, CoreBiome, Carb10, Yuth, and the stimulating innovations, TeaCrine and Dynamine. The ingredient house has just as much to offer the performance side of supplements as it does health and wellness, if not more so, which is something one of its most recent innovations feeds into, introducing Rējen.
Rējen is a branded fulvic and humic acid ingredient carrying over 70 trace minerals, with fulvic and humic acid content that is said to exceed any other fulvic acid or shilajit Compound Solutions has tested globally. The idea behind the innovation is that modern agricultural soil is increasingly depleted, reducing the mineral density of fruits and vegetables. Rējen exists to replenish what diet alone no longer reliably provides, supporting energy, metabolism, and gut health.

Where Compound Solutions’ Rējen separates itself is in how it is produced. Most fulvic ingredients go through base-acid extraction, a chemical-heavy process that leaves residual impurities in the finished product. Rējen uses no chemicals in its separation process, resulting in a cleaner profile with notably low heavy metal content, something that cannot always be said for shilajit and conventional fulvic acids. It dissolves with a tea-like hue rather than the typical black, making it easy to formulate across powders, capsules, gummies, and the rising world of beverages.
Rējen is a genuinely well-rounded ingredient, covering trace mineral replenishment, gut health, energy, and metabolism in a single addition that works across any format. The variety of benefits makes it perfect for a premium multivitamin, superfood formula, addition to a digestion formula, or standalone to use where people please.
