美國Douglas Laboratories 5 -羥色氨酸 5-HTP 100粒 膠囊

產品描述
5-HTP 由 Douglas Laboratories® 提供，每粒素食膠囊含有 50 毫克從 Griffonia 植物種子中提取的天然 L-5 羥色氨酸 (5-HTP)。

血清素是一種重要的大腦神經傳導物質，在調節食慾、情緒和褪黑激素的產生方面起著關鍵作用。大腦中的血清素的存在與平衡的情緒狀態有關。 這部分是透過降低某些興奮性荷爾蒙（包括多巴胺和去甲腎上腺素）的活性來實現的。血清素還能作為大腦中的飽足訊號，自然地調節食物攝取量。 此外，作為褪黑激素的前體，血清素參與調節睡眠模式。

5-HTP 天然來自加納植物的種子，而色氨酸則是透過合成或細菌發酵產生的。 5-HTP 比色氨酸更容易進入大腦，因為它能夠穿過血腦屏障而不進行吸收競爭。 5-HTP 的效果明顯優於色氨酸。在臨床實務中，普遍認為50毫克5-HTP大約相當於500毫克色胺酸。最後，研究表明，5-HTP 在高達 900 毫克的水平下仍然是安全的。 因此，5-HTP 是一種安全有效的腦血清素水平調節劑。

建議用法
每日一至兩粒膠囊，兩餐之間服用或遵醫囑。維生素B6是5-HTP轉化為血清素所必需的；因此，為了獲得5-HTP的最佳效果，必須確保攝取足夠的維生素B6。

副作用
目前尚無不良副作用報告。

保存
請置於陰涼乾燥處，避免陽光直射。請將本品放在兒童不能接觸的地方。

DESCRIPTION
5-HTP, provided by Douglas Laboratories®, contains 50 mg of natural L-5 Hydroxytryptophan (5-HTP) extracted from seeds of the Griffonia plant in each vegetarian capsule. Serotonin, an important brain neurotransmitter, is key in the regulation of appetite, mood, and melatonin production. The presence of serotonin in the brain is associated with a balanced emotional state.  This is achieved in part by decreasing the activity of certain excitatory hormones, including dopamine and noradrenaline. Serotonin also acts as a satiety signal in the brain, thereby naturally regulating food intake.  Additionally, as a precursor of melatonin, serotonin is involved in regulating sleep patterns. 

5-HTP is derived naturally from the seeds of the Griffonia plant, unlike tryptophan which is produced synthetically or through bacterial fermentation.  5-HTP crosses into the brain more readily than tryptophan as it is able to cross the blood-brain barrier without competition for uptake.  5-HTP is significantly more effective than tryptophan. In clinical practice, it has been commonly accepted that 50 mg of 5-HTP is roughly equivalent to 500 mg of tryptophan. Finally, research studies have shown 5-HTP to be safe at levels as high as 900 mg.  As a result, 5-HTP is a safe and effective brain serotonin levels.

SUGGESTED USE
One to two capsules per day, between meals or as directed by a physician. Vitamin B6 is necessary for the conversion of 5-HTP to serotonin; thus, to derive optimal benefits of 5-HTP, one must ensure an adequate intake of vitamin B6.

SIDE EFFECTS
No adverse side effects have been reported.
