Most companies use cheap, mass-produced ingredients, then dilute them heavily with water to keep costs low.
Luma Labs does the opposite.
They source their ingredients from the Rocky Mountains at over 7,500 feet above sea level, where harsh growing conditions put the plants under more environmental stress, creating stronger and more potent extracts.
So each serving delivers 1,200 mg of potent Mullein, Astragalus Root, and Licorice Root.
