5-HTP 100mg.

Pure Encapsulations

Enhances brain serotonin

*5-Hydroxytryptophan (5-HTP) is an intermediate in the natural synthesis of the essential amino acid, tryptophan, to serotonin. The enzyme tryptophan hydroxylase adds a hydroxyl group (OH) to tryptophan, forming the 5-HTP intermediate. In the body, it converts to serotonin with the removal of a carboxyl group (COOH) by a second enzyme. Serotonin is an important neurotransmitter involved in the regulation of endocrine and brain activity responsible for emotion, appetite and sleep/wake cycles. In clinical studies, administration of 5-HTP supported serotonin production. The 5-HTP supplied in this supplement is derived from the Griffonia simplicifolia plant.

Cat's Claw

Pure Encapsulations

Support for joint, cardiovascular, immune and gastrointestinal function

* Cat's claw, also known as Uncaria tomentosa, has been used traditionally in Peru for over 2,000 years. Alkaloids, phenols, sterols and glycosides comprise some of the naturally occurring constituents of this herb. The effects of these compounds are far- reaching and include support for joint function, gastric and intestinal health, cellular protection and immune activity. In a 52-week, randomized, double blind trial, cat's claw extract promoted joint comfort in volunteers. A 4-week study also suggests that cat's claw has the ability to promote joint comfort, in part by maintaining healthy prostaglandin metabolism. Other mechanisms of action that may account for these effects include protecting from oxidative stress and supporting healthy cytokine production. Studies involving cultured gastric epithelial cells suggest that cat's claw may provide important antioxidant protection for gut health. Cat's claw alkaloids have been specifically associated with enhancing immune system cell function, including phagocytosis and macrophage activity. Cardiovascular support properties include support for healthy vascular and platelet function. Preliminary evidence suggests that cat's claw may provide protective support for healthy breast cell function. Cat's claw may be contraindicated for individuals who are taking blood thinning or antihypertensive medications due to a potential synergistic effect.

Grapefruit Seed Extract

Pure Encapsulations

Promotes the balance of intestinal microorganisms and maintains a healthy gastrointestinal tract

*Grapefruit seed extract is a highly concentrated fungal and microbial balancing extract. Grapefruit seed extract exerts these effects within the gastrointestinal (GI) tract, promoting healthy microflora and gut ecology. A preliminary clinical trial reported that grapefruit seed extract supplements helped support healthy GI function and comfort. An in vitro study using human skin fibroblast cells indicated that grapefruit seed extract promoted healthy gram-positive and gram-negative balance. Other studies support these findings, citing that grapefruit seed extract promotes a healthy environment when exposed to a wide range of bacterial biotypes.

Gymnema Sylvestre 75

Pure Encapsulations

Supports pancreas function and healthy glucose metabolism

*Gymnema sylvestre has been used traditionally in India for over 2,000 years. Among the active constituents of Gymnema sylvestre are the gymnemic acids. Several mechanisms may account for the ability of this extract to nutritionally support the pancreas and, when used as part of the diet, to maintain healthy glucose metabolism. Preliminary research involving human volunteers in two separate trials suggests that Gymnema sylvestre promotes healthy pancreatic cell function. Studies also reveal the ability of Gymnema sylvestre to support enzyme activity for glucose utilization and to promote healthy glucose uptake into the intestines. Furthermore, this extract has the potential to support healthy lipid and triglyceride metabolism.

90 Vegetable Capsules

Supplement Facts each vegetable capsule contains: Gymnema sylvestre extract 250 mg.   (standardized to 75% gymnemic acids) vitamin C (as ascorbyl palmitate) 10 mg. 1–3 capsules per day, in divided doses, with meals.

L-Carnitine 

Pure Encapsulations

*l-Carnitine is an amino acid found abundantly in skeletal muscle. It functions primarily to regulate fat metabolism, and also acts as a carrier of fatty acids into the mitochondria, where they are oxidized and converted to energy. l-Carnitine also facilitates the removal of short and medium chain fatty acids from the mitochondria that accumulate during normal metabolic processes.

l-Glutamine 500mg

Pure Encapsulations

Muscle mass and gastrointestinal tract support

* l-Glutamine is the most abundant amino acid in the body. In times of metabolic stress, glutamine is utilized by the body for tissue repair, gastrointestinal tract support, and natural defense system function. Glutamine plays a large role in maintaining healthy intestinal integrity by enhancing the intestine's protective mucosal lining. In addition, glutamine is important in the preservation of muscle mass.

l-Methionine

Pure Encapsulations

Liver and pancreas support

* l-Methionine is an essential amino acid that contains sulfur, which is an important component of cartilage building blocks such as proteoglycans and glycosaminoglycans. Methionine is incorporated into tissue proteins and enzymes and is a component of active peptides, including methionine enkephalin and various endorphins. One of the main roles of methionine is as a methyl donor, contributing to numerous physiological pathways in the body including formation of myelin components. In one such pathway, methionine converts to s-adenosylmethionine. Studies have indicated that l-methionine may promote healthy cellular metabolism, enzyme activity, and glutathione concentration. Methionine, like choline and betaine, is also a lipotropic compound supporting lipid metabolism and enhancing healthy hepatic function. In combination with antioxidants, methionine may play a role in healthy pancreas function.

60 Capsules

Supplement Facts each vegetable capsule contains: l-methionine (free- form) 375 mg. 2–3 capsules per day, in divided doses, between meals.

NAC 600mg.

Pure Encapsulations

Powerful free radical scavenger

* N-Acetyl-l-Cysteine (NAC) is a derivative of the dietary amino acid l-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. By disrupting disulfide bonds, NAC thins mucus. It is a powerful free radical scavenger and thus supports the body's natural defense system. NAC supports tissue levels of glutathione, a key component of the antioxidant defense system. It also has the ability to help chelate heavy metals.

Policosanol 10mg

Pure Encapsulations

Supports healthy lipid metabolism in some individuals

*Policosanol is a mixture of long-chain aliphatic alcohols that naturally occur in sugar cane. Over a decade of short-term and long-term clinical research involving thousands of subjects reveals the safety and tolerability of policosanol. The promising results of randomized, double-blind placebo-controlled trials, including comparative studies, suggest that policosanol supports cardiovascular health. Though the mechanism for cardiovascular support of this substance remains unclear, policosanol may act in part by providing antioxidant protection, promoting healthy platelet function, and supporting healthy lipid metabolism. At the highest dosage recommended by Pure Encapsulations, policosanol may support healthy triglyceride metabolism in some individuals.

Vitamin E

Pure Encapsulations

(with mixed tocopherols)

*Naturally occurring tocopherols (d-alpha, beta and gamma) are the most biologically active forms of vitamin E. Vitamin E, a powerful chain-breaking antioxidant and free radical scavenger, is considered the first line of defense against lipid peroxidation. It protects the integrity of the body's cellular membranes, and has the ability to unite with oxygen and prevent it from being converted into toxic peroxides. Vitamin E plays a beneficial role in the cellular respiration of muscles, especially cardiac and skeletal muscles. It also supports healthy blood vessel function. In addition, vitamin E plays a role in nucleic acid and protein metabolism, mitochondrial function, and hormone production.
