解鎖男性耐力：『L-精胺酸』血液循環與恢復速度！🩸💪
L-精胺酸與男性健康：科學證據與功效L-精胺酸（L-Arginine）是一種半必需氨基酸，近年來因其對男性健康的潛在益處受到廣泛關注。研究表明，L-精胺酸能：促進睪固酮分泌改善血液循環增強勃起功能提升精子品質 L-精胺酸在男性健康中的作用機制1. 促進睪固酮分泌睪固酮對男性的生殖健康、肌肉維持及整體活力至關重要。L-精胺酸是體內一氧化氮（NO）的前體，NO 透過調節睪丸內的萊氏細胞（Leydig cells）影響睪固酮分泌。研究顯示，抑制NO的合成會影響睪固酮分泌，顯示NO在此過程中發揮調控功能（Welch et al., 1995）。研究顯示，補充L-精胺酸可透過促進黃體生成素（LH）分泌與抗氧化作用，維持睪固酮水平（Zeng et al., 2019）。 2. 改善血液循環與勃起功能陰莖的勃起功能與血流供應密切相關。L-精胺酸能夠提升NO生成，促進血管擴張並改善血液循環。實驗顯示，對於因器質性因素導致勃起功能障礙的男性，高劑量口服L-精胺酸可顯著改善性功能，尤其對於原本NO產生量較低者效果更為顯著 (Chen et al., 1999)。 3. 提升精子生成與活力精子的數量與活動力是男性生育能力的重要指標。L-精胺酸補充可顯著提高精液中的精子濃度、活力與形態 (Ghanizadeh et al., 2020) 。研究發現，L-精胺酸可透過促進黃體生成素（LH）分泌及抗氧化系統，減輕高溫環境對雄性生殖功能的影響，進而維持精子活力與生育能力 (Zeng et al., 2019)。 4. 減少房事後的疲勞感，提升體力與恢復速度L-精胺酸能夠促進NO生成，進而增強血液循環，提高氧氣與養分輸送至組織，可能有助於加快恢復速度、減少疲勞感。研究發現，L-精胺酸可提高一氧化氮生成，增強運動耐力，並加速肌肉疲勞恢復 (Campbell et al., 2006)。補充L-精胺酸可顯著降低運動時的氧氣消耗，提高運動效率 (Bailey et al., 2010)。適合補充L-精胺酸的族群長期壓力大、精力不足的男性壓力影響NO的生成與血管功能，導致精力下降，而L-精胺酸可改善此問題。勃起功能不佳或勃起時間短者L-精胺酸透過NO途徑改善陰莖血流，有助於提升勃起功能（Klotz et al., 1999）。性慾降低或睪固酮分泌不足者由於NO對睪固酮合成有影響，L-精胺酸補充可能有助於維持正常的睪固酮水平（Welch et al., 1995）。 結論L-精胺酸在促進男性健康方面具有多重作用，包括提升睪固酮水平、改善血液循環、增強勃起功能，以及提升精子品質。 【日本黑瑪卡＋黃精粉末復方推薦】提升耐力、強硬有感、持久不懈Capi N Tabi© 日本進口：黑瑪卡軟膠囊『激發補給品 8000』
