2 . The method claim 1 , wherein said agent comprises medium chain triglycerides.
3 . The method of claim 2 , wherein modulating mitochondrial function comprises reducing oxidative damage or improving mitochondrial efficiency.
4 . The method of claim 2 , further comprising detecting the modulation of mitochondrial function.
5 . The method of claim 4 , wherein the detecting comprises detecting modulation of State I respiration, detecting modulation of State II respiration, detecting modulation of State III respiration, detecting modulation of State IV respiration, detecting modulation of RCR, detecting modulation of uncoupling protein activity, detecting lipid oxidation, and detecting protein oxidation.
6 . The method claim 2 , wherein said medium chain triglycerides are administered medium chain triglycerides are administered at a dose of about 0.1 g/kg/day to about 10 g/kg/day.
7 . The method of claim 6 , further comprising coadministering L-carnitine or a derivative of L-carnitine.
8 . The method claim 7 , wherein said L-carnitine or said derivative of L-carnitine is administered at a dose of about 0.5 mg/kg/day to about 10 mg/kg/day.
9 . The method of claim 2 , wherein said medium chain triglycerides are emulsified.
10 . The method of claim 9 , further comprising coadministering L-carnitine or a derivative of L-carnitine.
11 . The method of claim 10 , wherein said emulsified medium chain triglycerides and L-carnitine or a derivative of L-carnitine are administered in a formulation comprising 10-500 g emulsified medium chain triglycerides and 10-2000 mg L-carnitine or derivative of L-carnitine.
12 . The method of claim 2 , wherein the agent further comprises a ketone body or metabolic precursor of a ketone body.
13 . The method of claim 12 , wherein the ketone body is selected from a group consisting of β-hydroxybutyrate, acteoacetate, metabolic precursors of β-hydroxybutyrate or acteoacetate, and mixtures thereof.
14 . The method of claim 13 , wherein the metabolic precursor is a physiologically acceptable salt or ester of a polymer or oligomers wherein in each case the number of subunit repeats is selected such that the polymer or oligomers is readily metabolized on administration to a human or animal to provide elevated ketone body levels in the blood.
15 . The method of claim 14 , wherein the metabolic precursor is selected from the group consisting of:
wherein n is an integer of 0 to 1,000, and m is an integer of 1 or more, a complex thereof with one or more cations or a salt thereof for use in therapy or nutrition.
16 . The method of claim 2 , wherein the agent further comprises a metabolic adjuvant.
17 . The method of claim 16 , wherein the adjuvant is selected from a group consisting of a vitamin, a mineral, an antioxidant, an energy-enhancing compound, and mixtures thereof.
18 . The method of claim 17 , wherein the energy-enhancing compound is selected from a group consisting of Coenzyme CoQ-10, creatine, L-carnitine, n-acetyl-carnitine, L-carnitine derivatives, and mixtures thereof.
19 . The method of claim 17 , wherein the vitamin is selected from a group consisting of ascorbic acid, biotin, calcitriol, cobalamin, folic acid, niacin, pantothenic acid, pyridoxine, retinol, retinal (retinaldehyde), retinoic acid, riboflavin, thiamin, benfotiamine, a-tocopherol, phytylmenaquinone, multiprenylmenaquinone, pyridoxine derivatives, pantothenic acid, and mixtures thereof.
20 . The method of claim 17 , wherein the mineral is selected from a group consisting of calcium, magnesium, sodium, potassium, zinc, copper, aluminum, chromium, vanadium, selenium, phosphorous, manganese, iron, fluorine, cobalt, molybdenum, iodine and mixtures thereof.
21 . The method of claim 6 wherein the agent further comprises a triglyceride containing an essential fatty acid from a group consisting of 18:2 n-6 (linoleic), 18:3 n-6, 20:3 n-6, 20:4 n-6 (arachidonic), 24:4 n-6, 24:5, n-6, 22:5 n-6, 18:3 n-3 (alpha-linolenic), 18:4 n-3, 20:4 n-3, 20:5 n-3 (eicosapetaenoic), 22:5 n-3, 24:5 n-3, 24:6 n-3, 22:6 n-3 (docosahexanoic).
