There are seven noteworthy classes of supplements: sugars, fats, fiber, minerals, protein, vitamin, and water. Most foods contain a blend of a few or the greater part of the supplement classes, together with different substances, for example, toxins or different sorts. A few supplements can be stored internally (e.g., the fat solvent vitamins), while others are required pretty much persistently. Weakness can be caused by an absence of required supplements or, in extraordinary cases, a lot of a required supplement.
