USE FAT AS FUEL - L-Carnitine is an amino acid derivative used to help fat enter the mitochondria. Dietary fats and stored body fat are rich sources of energy, but they require carnitine for transport into the mitochondria. Simply put, without adequate carnitine, fat cannot be used as a fuel source in the body. *

DESIRED FORM - Carnitine Synergy uniquely combines L-carnitine and its acetylated form into one capsule in a 4:1 ratio. *

VEGETARIANS MAY NEED SUPPLEMENTAL CARNITINE - L-carnitine occurs naturally in all foods, with animal proteins being the richest sources--particularly red meat and dark meats, such as lamb, beef, and dark meat poultry. Minuscule amounts are present in plant foods. *

Maintain Healthy Liver - Although the brain typically gets credit for orchestrating everything that goes on in the body, the liver is another organ that is tasked with a broad range of metabolic and biochemical functions that affect overall health. If liver function is compromised in some way, these critical tasks may not occur optimally.*

Contains Liver Supportive Ingredients - Hepatatone Plus consists of a blend of botanical and mushroom extracts, along with N-Acetyl-L-Cysteine (NAC), a derivative of the amino acid cysteine, which has powerful antioxidant and liver-protective actions. In addition to protecting the body from oxidative stress, NAC assists with the formation of glutathione often called the body's "master antioxidant," and a crucial compound for effective detoxification in the liver. *

Protects Against Oxidative Damage - The mushroom extracts and herbal ingredients in this product are designed to protect liver cells against oxidative damage which may affect the function of the liver. The ingredients also actively contribute to detoxification processes in the liver by supplying nutrients that may enhance the biochemical reactions involved in neutralizing harmful substances. *

STIMULATE BUILDING OF PROTEIN IN MUSCLE - BCAAs are unique in that they are a direct source of energy for skeletal muscles while also serving as intermediates in the ATP-producing citric acid cycle. They stimulate the building of protein in muscle, help reduce muscle breakdown during exercise and regulate protein metabolism throughout the body. *

BUILD MUSCLE TISSUE - BCAA Powder combines the branched-chain amino acids (BCAA)- leucine, isoleucine, and valine- along with the amino acid, L-glutamine for a synergistic effect in building muscle tissue and supporting the immune system. *

REDUCE MUSCLE BREAKDOWN - BCAA's help reduce muscle breakdown during exercise and regulate protein metabolism throughout the body. *

Balanced Essentials - This product provides amino acids which are considered to be 'essential,' meaning they cannot be made in the body and, thus, must be obtained through diet or supplementation. Includes l-phenylalanine, l-histidine, l-tyrosine & more.

SUPPORT YOUR GUT - L-Glutamine is an amino acid with a vast array of functions and health benefits, derived from its ability to feed various cells in the body. Glutamine is essential to the health of the immune system and the digestive tract. In the gut, it promotes the health and proper functioning of mucosal cells, which are necessary for normal healing and repair. *

THERAPEUTIC DOSE - L-Glutamine powder contains 3000 mg of L-Glutamine per 3/4 teaspoon. *

POWERFUL HEALTH EFFECTS - Glutamine, like all amino acids, contains nitrogen, which is needed by many cells throughout the body - including immune, gut and muscle cells. Nitrogen is also a building block for proteins, antioxidants, neurotransmitters and DNA. Glutamine has a unique Robin Hood-like nature - it distributes nitrogen freely to the cells which need it most, giving your body powerful and wide-ranging health effects. *

USE FAT AS FUEL - L-Carnitine is an amino acid derivative used to help fat enter the mitochondria. Without adequate carnitine, fat cannot be used as a fuel source in the body. *

RAPID ABSORPTION - L-carnitine tartrate is a stable and moisture-resistant form of L-carnitine. This powder contains 700 mg of L-carnitine tartrate per 1/4 teaspoon, mixes easily in liquids and absorbs rapidly into the body. *
