Citrulline from watermelon has a variety of uses and benefits primarily in health and wellness. It is extracted mainly from the pulp and seeds of the watermelon. Some common uses include:
Boosting exercise performance
Citrulline is used in pre-workout supplements to improve exercise performance. It increases nitric oxide levels in the body which helps improve blood flow to muscles. This helps reduce fatigue and boosts the workouts by increasing endurance.
Promoting recovery
The higher blood flow that citrulline provides helps boost recovery after workouts by reducing muscle soreness. Watermelon juice is taken post-workout to help speed up recovery and reduce muscle soreness and dehydration.
Supporting cardiovascular health
Citrulline is used to help improve blood circulation and reduce blood pressure in people with hypertension and cardiovascular disease. This is because nitric oxide aids blood circulation which can help protect against heart disease.
Enhancing cognitive function
The increased blood flow to the brain that comes with citrulline may help improve cognitive function and focus. Some people take it to improve mental clarity and focus, especially when doing tasks that require a lot of concentration.
Managing erectile dysfunction
Citrulline has been studied as a potential treatment for mild to moderate erectile dysfunction. Improved blood circulation points the improved blood flow to the genital area which may help improve sexual function in men and women.
Skin health
Watermelon juice or citrulline extracts are used in cosmetics and skincare products to help improve skin hydration and reduce the signs of aging. Citrulline is also used in combination with other amino acids like arginine to help maximize the benefits of citrulline for skin health.
Aging and anti-aging treatments
Citrulline is used in skincare products aimed at reducing wrinkles and fine lines. This is because improved blood flow helps deliver nutrients to the skin which helps promote cell regeneration and youthful-looking skin.
With high citrulline content, watermelon offers a lot of benefits to the buyers. Some common benefits include:
Exercise and athletic performance
Watermelon citrulline and juice are usually taken by athletes to improve performance during workouts. Citrulline helps reduce fatigue, increases endurance and improves blood flow to the muscles. This makes it a common ingredient in pre-workout drinks and supplements.
Hydration
Watermelon is made up of around 92% water but also contains electrolytes and citrulline which help keep the body hydrated. This makes it a great choice for rehydrating after intense workouts or being outdoors in the heat.
Improved blood flow
Citrulline increases nitric oxide production which dilates blood vessels, improving blood circulation. This helps delivery of oxygen and nutrients to cells, and may help support cardiovascular health.
Muscle soreness and recovery
Watermelon juice after workouts may help reduce muscle soreness and promote faster recovery due to its citrulline content. Citrulline enables the body to remove ammonia from the muscles which helps reduce muscle soreness and boosts recovery.
Antioxidant properties
Watermelons contain lycopene and beta-carotene which are powerful antioxidants that help neutralize free radicals in the body. These free radicals cause oxidative stress and damage cells. The antioxidant properties help reduce the risk of chronic diseases and support the immune system.
Weight management
Watermelon is low in calories and high in water content which helps one feel full without consuming a lot of calories. Citrulline may also help regulate appetite and reduce cravings and thus assist in weight management or help with weight loss.
Skin health
Watermelon’s hydration, antioxidants and anti-inflammatory properties help support healthy skin by preventing damage from UV rays and pollution and helping to keep it hydrated and plump.
