Lentils

What it is: Lentils are the edible seeds of the Lens culinaris legume, notable for their high content of plant protein, dietary fiber, iron, and folate. They are a whole food source often processed into functional nutrition ingredients.
What it does: Lentil ingredients supply protein for muscle support, fiber for bowel regularity and microbiome health, and minerals like iron and folate that help with energy production and red blood cell health.
How it is used: Lentil extracts, powders, and isolates commonly appear in supplements for muscle support, digestive regularity, balanced plant-based diets, or to increase protein and fiber intake.
Natural sources and supplement forms: Naturally found in lentil seeds, these nutrients are used whole or processed into protein concentrates, powders, or fibers for supplements such as meal shakes, bars, and capsules.
Why it appears in supplement formulas: Lentil-based ingredients offer a well-tolerated, plant-sourced alternative for protein and fiber, useful for vegan, vegetarian, or allergen-conscious nutrition, and can help support digestive and overall health.
What to know before use: Lentil-based products are typically well tolerated, but those with legume allergies or sensitivities should seek medical advice before use.
