Tested Nutrition offers a range of high-quality sports supplements, and one notable product is Tested Nitrates. Derived from natural nitrates found in red spinach, this supplement plays a crucial role in enhancing physical performance by converting into nitric oxide upon consumption. Nitric oxide acts as a potent vasodilator, expanding blood vessels to facilitate improved blood flow and oxygen supply to muscles during exercise. With an impressive 400 mg of natural nitrates per two servings, Tested Nitrates uniquely supports nitric oxide levels. Gluten-free and vegan-friendly, it comes in a container with 240 vegetarian capsules, providing 60 full servings. The recommended dose is four vegetarian capsules, emphasizing its commitment to clean and effective nutrition. Tested Nutrition's Tested Beta-Alanine stands out with its pure beta-alanine in convenient capsule form. Beta-alanine, a non-essential amino acid, is converted to carnosine by muscle cells, offering various benefits for endurance and high-intensity exercise. What distinguishes Tested Beta-Alanine is its capsule presentation, a departure from the typical powdered form. Each capsule contains 750 mg of beta-alanine, and a container holds 180 capsules, providing 45 servings. The suggested use is four capsules once daily, making it a practical and efficient addition to any fitness regimen.
