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.
What does amortization mean? In accounting we use the word amortization to mean the systematic allocation of a balance sheet item to expense (or revenue) on the income statement. Conceptually, amortization is similar to depreciation and depletion. An example of amortization is the systematic allocation of the balance in the contra-liability account Discount of Bonds Payable to Interest Expense over the life of the bonds.
