    A: Magnesium stearate is a common flow agent used in supplement manufacturing to prevent ingredients from sticking to equipment. While generally considered safe, some supplement purists prefer products without it. Superior Labs formulates without magnesium stearate, using only pure L-Arginine in vegetable capsules for maximum purity.

    A: Superior Labs recommends following the dosage on the label. For L-Arginine supplementation for nitric oxide support, typical dosages range from 1,500-3,000mg per day (3-6 capsules). Start with a lower dose to assess tolerance and increase gradually as needed.

    A: Yes, L-Arginine can be taken before bed. Some research suggests that nitric oxide production during sleep may support recovery and growth hormone release. However, the timing is flexible — L-Arginine can be effective when taken at any time of day, with or without food.
