Get a high-potency amino acid boost for circulatory health and more with Swanson Arginine AKG Powder! The amino acid L-arginine is involved in many vital processes in the body, from detoxification to energy production, but it is in circulatory health where it has its greatest impact. L-arginine is a key player in the body's production of nitric oxide, a compound that helps keep blood vessels dilated to promote blood flow and help maintain blood pressure already within a normal range. This makes L-arginine beneficial for overall cardiovascular maintenance and in areas such as sexual function that depend largely on circulatory status. Our Arginine AKG Powder delivers a super-potent 5 grams per serving—a much higher dosage than other forms. This arginine powder features a delicious natural lemon flavor and dissolves readily in water to create a great-tasting nutritional drink.

Caution: Contains xylitol. Keep out of reach of pets; do not feed to pets.

  1. What is L-Arginine AKG, and what are the benefits of taking it?
    L-Arginine AKG (arginine alpha-ketoglutarate) combines the amino acid L-arginine with alpha-ketoglutarate (AKG), a naturally occurring compound involved in cellular energy metabolism. L-arginine serves as a precursor to nitric oxide, which helps support healthy blood flow and circulation. Swanson Maximum Strength L-Arginine AKG Powder delivers 5 grams per serving to support exercise performance, healthy circulation, cardiovascular wellness, and an active lifestyle.
  2. How does L-Arginine AKG support nitric oxide production?
    L-Arginine is the amino acid the body uses to produce nitric oxide, a signaling molecule that helps relax blood vessels and support healthy circulation. Healthy nitric oxide production promotes normal blood flow, helping deliver oxygen and nutrients to working muscles and other tissues. Swanson Maximum Strength L-Arginine AKG Powder provides a convenient way to support nitric oxide production before exercise or as part of your daily wellness routine.
  3. How does L-Arginine AKG support exercise performance?

Powder also allows for flexible serving sizes and is an excellent option for individuals who prefer not to swallow multiple capsules. Swanson Maximum Strength L-Arginine AKG Powder mixes easily with water and is ideal for use before workouts or as part of your daily supplement routine.
  5. What is alpha-ketoglutarate (AKG), and why is it combined with L-arginine?
    Alpha-ketoglutarate (AKG) is a naturally occurring compound involved in the Krebs cycle, the process cells use to produce energy. When combined with L-arginine, AKG complements the amino acid's role in supporting nitric oxide production and healthy circulation while contributing to normal cellular energy metabolism. Swanson Maximum Strength L-Arginine AKG Powder combines these ingredients to provide comprehensive support for exercise performance, healthy blood flow, and overall cardiovascular wellness.
