L-Arginine Powder 454g – Now<\/strong><\/h2>\n

L-Arginine Powder 454g – Now<\/strong> is a powdered food supplement<\/strong>, with free-form L-arginine<\/strong> as its only ingredient. This amino acid is involved in several metabolic pathways, including the synthesis of nitric oxide<\/strong> and the urea cycle<\/strong>. In addition, the powder format allows the intake to be adjusted conveniently, according to the label recommendation.<\/p>\n

What it is used for<\/strong><\/h3>\n

L-arginine<\/strong> participates in the production of nitric oxide<\/strong>, a mediator involved in the normal function of blood vessels. Therefore, it can be part of the routines of adults with an active lifestyle who are looking for an isolated amino acid supplement. On the other hand, L-arginine also acts as a substrate in protein synthesis<\/strong> and nitrogen metabolism. Thus, the product can be used as part of a balanced diet and an appropriate training plan.<\/p>\n

Composition or Main Characteristics<\/strong><\/h3>\n
    \n
  • L-Arginine (free form)<\/strong>: 6 g (6,000 mg) per serving.<\/li>\n
  • Single-ingredient<\/strong> formula, with no amino acid blends.<\/li>\n
  • Suitable for vegans<\/strong>; Kosher<\/strong> and Halal<\/strong> certifications.<\/li>\n
  • Non-GMO<\/strong> and steroid-free.<\/li>\n
  • Not made with wheat<\/strong>, gluten<\/strong>, soy<\/strong>, milk<\/strong>, egg<\/strong>, fish<\/strong>, crustacean shellfish<\/strong>, tree nuts<\/strong> or sesame<\/strong> ingredients.<\/li>\n
  • Produced in a GMP<\/strong> facility that processes other allergens; therefore, traces may be present.<\/li>\n<\/ul>\n

    Directions for use<\/strong><\/h3>\n

    Mix 2 level teaspoons<\/strong>, once daily, in at least 240 ml<\/strong> of water or juice. In general, intake is recommended on an empty stomach<\/strong>, as this may support amino acid absorption. However, if gastrointestinal discomfort occurs, consider taking it with food and assess individual tolerance. Additionally, follow the indicated dose and do not exceed the recommended daily intake.<\/p>\n

    Important information<\/strong><\/h3>\n

    For adults only<\/strong>. Not recommended during pregnancy<\/strong> or breastfeeding<\/strong>. In addition, consult a healthcare professional if you are taking medication, particularly antihypertensives<\/strong>, anticoagulants\/antiplatelet agents<\/strong> or antidiabetics<\/strong>, as L-arginine may influence vascular tone and insulin response. Likewise, seek advice if you have asthma<\/strong> or kidney disease<\/strong>, or if you are planning surgery.<\/p>\n

    Avoid use in cases of glaucoma<\/strong> or herpes simplex<\/strong>, unless clinically indicated. However, if you have a history of myocardial infarction<\/strong> or established coronary artery disease<\/strong>, do not use the product. Therefore, discontinue use and seek guidance if adverse reactions occur.<\/p>\n

    Store in a cool<\/strong>, dry<\/strong> place away from light<\/strong> after opening. Therefore, keep out of reach of children.<\/p>\n","protected":false},"excerpt":{"rendered":"
