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.
While theoretically amortization is used to account for the decreasing value of an intangible asset over its useful life, in practice, many companies will amortize what would otherwise be one-time expenses by listing them as a capital expense on the cash flow statement and paying off the cost through amortization, thereby improving the company's net income in the fiscal year or quarter of the expense.
