Why is the capsule form of L-arginine more convenient than powder?

Swanson L-Arginine comes in capsules containing the free amino acid. Each capsule contains a fixed amount of the substance — 500 mg — which makes it possible to track your daily intake precisely without having to weigh powder or use measuring scoops.

Capsules are easy to take with you — in your gym bag, on a trip or to work. They do not need to be mixed with liquid just before taking and have no pronounced taste or smell, which matters for those who are sensitive to the taste of amino acids in powder form.

This format also makes it easier to fit the supplement into an established nutrient regimen: it is easy to follow the directions on the label — 2 capsules a day with water, preferably 30 minutes before a meal or a workout. This is especially important if L-arginine is used in combination with other supplements and you need to avoid accidentally exceeding the intended dose.
