5HTP 100 mg 180 vcaps by Pure Encapsulations,5-Hydroxytryptophan (5-HTP) is an intermediate in the natural synthesis of the essential amino acid, tryptophan, to serotonin. In clinical studies, administration of 5-HTP increased serotonin levels. 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.

Douglas Labs Amino Blend 740 mg 100 caps contain a nutritionally balanced mixture of essential, conditionally essential, and important non-essential amino acids in their physiological L-Crystalline forms. AminoBlend capsules may be a useful nutritional adjunct for individuals who wish to obtain a balanced spectrum of nutritionally important amino acids. Amino acids have many functions in the body. They are the building blocks for all body proteins— structural proteins that build muscle, connective tissues, bones and other structures, and functional proteins in the form of thousands of metabolically active enzymes. Amino acids provide the body with the nitrogen that is essential for growth and maintenance of all tissues and structures. Proteins and amino acids also serve as a source of energy, providing about 4 calories per gram. Aside from these general functions, individual amino acids also have specific functions in many aspects of human physiology and biochemistry. Amino acids serve as precursors for many nitrogenous substances. These include heme, purines, pyrimidines, hormones, and neuro-transmitters, including biologically active peptides. In addition, many proteins contain amino acids that have been modified for a specific function, e.g., calcium binding or collagen cross-linking. In the fasting state, blood plasma contains all metabolically important amino acids in characteristic concentrations, and each amino acid is present in a defined ratio relative to the others. After a meal, the ratios of plasma amino acids change to reflect amino acid intake, but return later to their original levels. Normal plasma amino acid levels are extremely susceptible to physiological state and show considerable variability. The plasma amino acid profile impacts the entry of individual amino acids into the tissues. Of particular importance is the effect of the plasma amino acid profile on the uptake of amino acids into the brain across the blood-brain barrier. As a result, alterations in the plasma amino acid profile can lead to changes in the amino-acid dependent synthesis of neurotransmitters and other nitrogenous compounds in the brain.

Douglas Labs L-Carnitine 250 mg 100 caps supply pure, natural L-Carnitine in capsule form. L-Carnitine may be a useful nutritional adjunct for individuals who wish to support heart muscle function or skeletal muscle performance. L-Carnitine is necessary for fatty acid metabolism and energy production in cardiac and skeletal muscle. It is involved in fatty acid oxidation as part of the carnitine shuttle. L-Carnitine shuttles fatty acids from the cytosol (the cell fluid) into the mitochondria (the cell’s powerhouses) for oxidation and energy production. L-Carnitine is necessary in muscle whenever fat is utilized as an energy source. Heart muscle always uses fat for its continuous energy demands. Skeletal muscle begins using fat only after its glycogen reserves are exhausted.

While its exact role in the body is not completely understood, it has demonstrated to be a strong antioxidant in several animal studies. It is also thought carnosine may participate in the regulation of enzyme activity and assist with the binding of heavy metals in the body. Carnosine is also thought to play a role in the pH regulation of lactic acid in the muscles during intense exercise, thereby assisting exercise performance.

Douglas Labs L-Cystine 500 mg 60 caps may be a useful dietary adjunct for individuals wishing to supplement their diet with this amino acid. Amino acids have many functions in the body.

Douglas Labs Taurine 500 mg 100 caps each contain 500 mg of pure crystalline taurine. Taurine capsules may be a useful dietary supplement for individuals who wish to enhance the body's taurine levels. Taurine is one of the most abundant free amino acids in the body. It is not incorporated into proteins, yet taurine is very important in metabolism and is present in particularly high levels in the brain, skeletal muscle, heart, and retina of the eye. Taurine is regarded as a conditionally-essential amino acid, because it can be synthesized by the body from the other sulfur-containing amino acids cysteine and methionine. Taurine synthesis is vitamin B6 dependent. Taurine is essential for infants where it plays important roles in the development of the nervous system, retina, and muscle tissue. Taurine is well known for its role in bile salt synthesis and has crucial functions in the liver's detoxification pathways. Taurine also appears to have a stabilizing effect on cell membranes and is important in maintaining normal extra- and intracellular distribution of calcium. This in turn has implications on neuronal excitability and the regulation of osmotic pressure. In the retina, taurine helps maintain the structure and function of the visual cells. In the diet, taurine is found in meat and fish, but not in plant foods.
