Key nutrients
All nutrient guidesFoods high in IronIron is a core component of hemoglobin, which carries oxygen through the blood. Steady iron intake supports energy levels and endurance.
Foods high in Vitamin B12Vitamin B12 is needed for red blood cell formation and nerve function. It is found almost exclusively in animal foods, so plant-based eaters often need a fortified source.
Foods high in Thiamin (B1)Thiamin, also known as vitamin B1, helps convert carbohydrates into usable energy, which supports steady energy through the day. It also plays a role in nerve function.
Foods high in Riboflavin (B2)Riboflavin, or vitamin B2, helps the body turn food into energy and supports healthy skin and eyes. It works alongside the other B vitamins in energy metabolism.
Foods high in Niacin (B3)Niacin, or vitamin B3, is central to energy production in nearly every cell and supports steady glucose response as part of that metabolic machinery.
Foods high in MagnesiumMagnesium is involved in hundreds of enzymatic reactions, including energy production, muscle relaxation, and sleep quality, which ties into recovery.
Foods high in IodineIodine is required to make thyroid hormones, which regulate metabolic rate and energy use throughout the body.
Sugar: foods to watchSugars are the fastest-digesting carbohydrates and cause the quickest rise in blood glucose. Moderating total sugar intake helps keep energy and glucose response steadier through the day.
