If you are an active person, chances are you do not need a protein supplement and using one will be counterproductive because of the extra calories (remember, 1 gram of protein provides as many kilocalories as 1 gram of sugar!). Athletes and vegetarians are special populations that may require supplements.
Amortization expense is a non-cash expense. Therefore, like all non-cash expenses, it will be added to the net income when drafting an indirect cash flow statement. The same applies to depreciation of physical assets, as well other non-cash expenditures, such as increases in payables and accumulated interest expenses.
Both depreciation and amortization (as well as depletion) are methods that are used to prorate the cost of a specific type of asset over the asset's life. It is important to mention that these methods are calculated by subtracting the asset's salvage value from its original cost. Amortization usually refers to spreading an intangible asset's cost over that asset's useful life. For example, a patent on a piece of medical equipment usually has a life of 17 years.
