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.
The whole purpose of the statement of cash flow is to adjust the net income reported on the profit and loss to the cash position of the company. Depreciation is a non-cash expense, and, therefore, is added back to net income as a first order of business on the statement of cash flow. Since depreciation is not a balance sheet item, QuickBooks, by default, does not even include it on the statement of cash flows.
