Citrulline

The Nitric Oxide Engine and Natural Booster of Energy and Male Vitality

Citrulline is a non-essential amino acid named after watermelon (Citrullus vulgaris), where it was first discovered. In the body, L-citrulline is converted into L-arginine and then into nitric oxide (NO) – a key molecule in regulating blood vessels, performance, and male sexual function.

Nitric oxide promotes vasodilation, or the widening of blood vessels, improving blood flow to the muscles, brain, and genitals alike. That’s why citrulline’s effects can be felt across athletic performance, recovery, and male potency.

Scientifically Proven Effects

1. Athletic Performance and Muscle Recovery
L-citrulline boosts nitric oxide levels, enhances oxygen and nutrient delivery to the muscles, reduces muscle fatigue, and accelerates recovery. In randomized trials, citrulline supplementation increased training repetitions and significantly reduced muscle soreness in the days following intense exercise

2. Male Potency, Erection and Genital Blood Flow
Nitric oxide is a primary regulator of erectile function: by promoting vasodilation, it improves penile blood flow and supports sustained erections. Clinical studies have shown that citrulline may improve erection hardness and sexual satisfaction in men with mild to moderate erectile dysfunction – naturally and without side effects

3. Vascular Protection and Cardiovascular Health
Beyond vasodilation, citrulline also has anti-inflammatory and antioxidant properties that may reduce arterial stiffness and support cardiovascular function. It can be particularly beneficial for those with metabolic syndrome, hypertension, or obesity

4. Cognitive and Nervous System Benefits
Improved blood flow doesn’t just benefit the muscles – studies suggest citrulline may increase brain perfusion, enhancing focus, memory, and cognitive performance, especially under stress or high mental load

Key Benefits for Men

  • Natural support for erectile function and blood flow
  • Boosted performance and endurance during workouts
  • Faster muscle recovery and less soreness
  • Improved oxygenation and circulation
  • Support for cardiovascular health and vascular flexibility

Why We Use Citrulline in Lost Garden Formulas
Citrulline is a silent powerhouse – working behind the scenes but delivering visible results. We use it in targeted formulations that promote performance, male vitality, and cellular-level regeneration. It works especially well in synergy with maca, ginseng, and saw palmetto, creating a naturally potent combination for blood flow, hormonal balance, and masculine energy – effectively and safely
