Without Compromise Since 1996

Founded in 1996, NutraBio is the original No Proprietary Blend, No B.S. honest brand. 15 years ago we revolutionized the supplement industry by introducing 4 quality commitments:

1. NO proprietary blends and full label disclosure
2. NO fillers, excipients, or additives (except flavor)
3. Full efficacious dosages of every active ingredient
4. Manufacturing our own products to control every aspect of quality.

Two decades ago we set the goal of providing our customers with the most effective, clean and honest supplements available. Since that very first day, we have led the charge in supplement innovation with science-backed therapeutic doses and full label disclosure.

We manufacture our products in our own FDA registered and audited facility. We are GMP certified and manufacture to exceed 21 CFR Part 111 cGMP regulations. We don't compromise on quality so you don't have to compromise on results.

L-Citrulline is an amino acid that numerous health and athletic performance benefits.

During the past decade research on L-Citrulline has shown to play an important role in nitric oxide production, vascular health, muscle protein synthesis, ammonia elimination and immune function.*

L-Citrulline is converted to L-Arginine in the body to support L-Arginine and nitric oxide levels. Increased production of nitric oxide promotes vascular dilation which improves oxygen and blood circulation throughout the body. L-Citrulline can also support heart health.*

L-Citrulline can also relieve muscle fatigue through ammonia elimination. L-Citrulline helps to rid the body of ammonia, a toxic byproduct of protein metabolism and provides a readily available substrate for arginine production. L-Citrulline is involved in the formation of urea in the liver which plays an important part in the removal of waste created by the digestion, absorption and metabolism of proteins.*
