Now Foods Double Strength 5-HTP is a dietary supplement that includes a high dose of 5-hydroxytryptophan. It is accompanied by substances strengthening and supplementing its action, namely vitamins B3 and B6, glycine, taurine and inositol.

The supplement supports the work of the nervous system, promotes the reduction of symptoms of depression, facilitates a stable and positive mood. Works well in the fight against insomnia and sleep disorders. In addition, it regulates the appetite and can reduce the appetite for sweets.

5-HTP (5-hydroxytryptophan) is a chemical compound belonging to amino acids, naturally produced in the human body from tryptophan. It is necessary for the synthesis of serotonin, and also supports the formation of dopamine, norepinephrine and melatonin. As one of the few compounds it has the ability to overcome the blood-brain barrier.

5-HTP strongly affects serotonin levels in the brain, which results in specific effects associated with the functioning of the nervous system. Thanks to the increase in the serotonin level, the mood and mental well-being improve. In addition, it is easier to control the emotions, and also restrain unjustified fears and anxiety.

The right level of serotonin is important for one more reason - it allows you to create the right amount of melatonin. It determines the normal circadian rhythm and optimal sleep. For this reason, 5-HTP is ideal for people suffering from insomnia or sleep disorders.

Vitamin B3 (niacin) has a significant effect on the work of the nervous system, shows soothing and calming properties. It supports the strengthening of cognitive functions and promotes mental fitness. Its deficiency correlates with a higher incidence of depression and insomnia. It is worth knowing that with a drastic decrease in niacin concentration, it is synthesized in the body from tryptophan, which often results in its deficiency and inability to produce the right amount of serotonin and melatonin. As a result, mood disorders and sleep problems may occur.

Vitamin B6 (pyridoxine) is actively involved in the production of neurotransmitters that affect, among others, the mood and cognitive functions. Its deficit increases the risk of depression and anxiety disorders, causes problems with memory, makes it difficult to focus attention and promotes the weakening of intellectual performance. Leveling the amount of this vitamin has a positive effect on the quality of sleep and facilitates the fight against insomnia.

Glycine is one of the endogenous amino acids, distinguished by its very simple structure and specific action. This substance is extremely active in the central nervous system, where it acts as an inhibitory neurotransmitter. It is also a co-agonist of NMDA receptor, thanks to which it optimizes glutamatergic transmission and can alleviate the negative symptoms of some psychiatric disorders (including schizophrenia). In addition, it has a beneficial effect on the mood and quality of sleep.

Taurine is a non-protein amino acid naturally synthesized in the body. It shows neuroprotective properties and supports the strengthening of cognitive functions. It also has a positive effect on the nervous system, inhibits its hyperactivity, which results in reduced anxiety and over-stimulation.

Inositol is a compound known as pseudovitamin, which works in a similar way to B vitamins. It is produced in the human body in small amounts. It is part of the cell membrane structures and is involved in the transmission of nerve impulses. Intellectual performance, the ability to focus attention, the speed of thought processes, and clarity of mind depend on its availability. Researches also suggest that inositol can increase the sensitivity of serotonin receptors, which would explain its positive effect on mood and antidepressant effects.

In conclusion, Now Foods Double Strength 5-HTP is a broad-spectrum supplement. By increasing serotonin levels, it promotes mental well-being and alleviates depression and anxiety symptoms. In addition, it supports the fight against sleep disorders and insomnia. It is also recommended for people struggling with obesity, especially if it is due to overeating and unrestrained appetite for sweets.

Vitamin B3


Vitamin B3 (vitamin PP, niacin, nicotinic acid, nicotinamide) is niacinamide niacin. It is used in interaction with vitamins B1, B2 and B6 in the synthesis of hormones during lactation. It provides proper functioning of the brain and nervous system. It is helpful in inflammatory conditions of the skin. Required for synthesis of sex hormone, estrogen, testosterone, cortisone, and insulin. It does not lose its properties in the manufacturing and storage. The source of acquiring vitamins PP are both products of animal origin (the lean meat, eggs, fish) and vegetable origin (dates, figs, hazelnuts, plums).
Dosage: 2-12 mg / day for children, 14 mg / day for women, 16 mg / day for men and 17-18 mg / day for pregnant or nursing women.


Vitamin B6


Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine) is soluble in the liquid. It participates in the metabolism of proteins, fats and carbohydrates. By reducing the amount of fat in the blood do not enable deposition of the body. It helps the absorption of magnesium and vitamin B12 (cobalamin). It works on the muscle antispasmodic and anti-inflammatory pain in the joints. It acts anti. It provides efficient operation of the brain. It increases energy increasing vigor of a man. The demand for vitamin B6 increases during pregnancy and breast-feeding infants. The natural product is: yeast, eggs, wheat germ, meat (liver), wheat bran, nuts, peanuts peanuts, soybeans. There is a hypothesis that can be synthesized by intestinal bacteria.
Deficiency of vitamin B6 causes abnormal metabolism of proteins, decrease in lymphocytes in the blood, causes a feeling of lethargy and fatigue intensifies.
Dosage: 1.5-2.5 mg daily (increased demand during pregnancy and lactation).


Pyridoxine hydrochloride


What is pyridoxine hydrochloride?

Pyridoxine hydrochloride is a basic, the most commonly used form of vitamin B6 in supplements and fortified foods. It is a vitamin soluble in water. It converts to the active form of the vitamin - pyridoxal phosphate.

Vitamin B6 is a cofactor in many enzymatic reactions. It takes part in the production of many neurotransmitters, such as GABA, serotonin and catecholamines and it takes part in the metabolism of amino acids, carbohydrates and lipids. It is an important factor for the process of the creation of red cells and hemoglobin and its deficit may be one of the factors causing anemia. This vitamin contributes to maintaining proper energy metabolism and is important for maintaining well-being and good psychological condition. Its presence supports the breakdown of pro-inflammatory homocysteine to cysteine and further metabolites, thanks to which it may decrease the risk of atherosclerosis and cardiological incidents.

Pyridoxine hydrochloride may be found in many vitamin B complexes and vitamin-mineral preparations available in the offer of

5-HTP (5-hydroxytryptophan)


5-HTP (5-hydroxytryptophan) is a metabolite of essential amino acid, tryptophan, involved in the synthesis of serotonin which is a neurotransmitter and a hormone responsible for the quality of sleep (melatonin). Used in medicine as an adjuvant, to a small extent supporting the treatment of depression and insomnia. Due to the presence of melatonin at the same time it is improving the quality of sleep and improving the regeneration process.
5-HTP is a component of supplements supporting the production of growth hormone and it is a part of some fat reducers (reducing appetite).
Dosage: Doses commonly used in supplements, depending on the purpose: 100-500 mg daily in divided doses, including approx. 50-150 mg before bedtime.


Griffonia Simplicifolia extract


Extract Griffonia Simplicifolia is the source derivative of tryptophan (5-HTP), an important neurotransmitter involved in the synthesis of serotonin, and indirectly affects the production of melatonin (the hormone responsible for sleep). It is used to treat depression and inactivity. In the sports supplementation it is used as a neurotransmitter responsible for the quality of sleep and improving the regenerative processes, moreover, it is a component of supplements which enhances the secretion of growth hormone and fat burners.
Dosage: In terms of 5-HTP from several dozen to several hundred mg per day.




Glycine is belongs to 22 essential amino acids (synthesized within the body) constructing proteins, and non-protein component of enzymes i.e. heme. It is a inhibiting neurotransmitter allowing for improvement in sleep comfort even at a dose of 3 g at bedtime. Glycine (as arginine) is a precursor of creatine. It is essential for the synthesis of a strong antioxidant - removing free radicals out of the body - glutathione. It is cholagogic and cholepoiteic. By interfering with the synthesis of growth hormone, accelerates the biological recovery of an organism. Naturally present in foods of plant and animal origin. In the sports supplementation is a component creatine stacks, amino acid supplements, protein supplements based on natural ingredients and carbohydrate and protein.




Taurine – non-protein amino acid containing sulphur, which is synthesized in the body from methionine and cysteine, present in sufficient amount in human or animal body (in the brain, heart and skeletal), although in some cases must be supplemented. Significantly affects the calcium content in the cells and stabilizes the water and electrolyte balance and maintains acid-base balance. Takes part in the synthesis of bile acids. In the body acts as a neurotransmitter and neuromodulator. It is an insulin-mimetic improving insulin metabolism, responsible for transport of nutrients (such as amino acids, glucose, creatine) to the cells and muscle tissue. These properties determine that it is a valued mono-preparation supplement and valuable addition to creatine and amino acid supplements, recommended for psycho-pchysically active people and athletes and other competitive sportsmen in pre- and post-workout periods.
Dosage: 3 grams per day.




Inositol is an organic compound from the group of B vitamins soluble in fluids, present in the natural or synthetic form, synthesized in plants, such as brewer's yeast, beans, grapefruit, cabbage, sprout of wheat, melons and animal (liver). Along with choline is included in the lecithin. It affects the cell nutrition of the central nervous system (brain) by reducing the level of LDL (bad cholesterol), this makes it applicable in treatment of Alzheimer's disease and atherosclerosis. It has a calming effect. There has been a beneficial effect of inositol on the skin and hair reported.
