All you need to know about Cysteine

What are the health benefits of cysteine?

Cysteine is an amino acid with antioxidant properties that can be used for treating angina, diabetes, flu and viruses, inflammation, bowel disease, osteoarthritis and joint inflammation, cardiovascular disease, angina and bronchitis. Those suffering from chronic obstructive pulmonary disease can take cysteine to encourage lung health. It can also be used to detox the body, and to enhance performance during sports.

Can cysteine treat diabetes?

Yes – cysteine can help treat and manage diabetes by keeping blood sugar low and reducing resistance to insulin, which in turn helps to prevent damage to blood vessels. A study has found that proteins rich in cysteine improve glucose metabolism in people who have type 2 diabetes. It also helps to reduce inflammation of blood vessels, which is often the cause of heart disease in people with diabetes.

What are the side effects of cysteine?

You should always consult your doctor before taking any amino acid supplements. Cysteine can interact with some medications such as those that suppress the immune system, causing such medications to increase in potency. If you are pregnant, you should speak with your doctor before taking cysteine.

Which foods contain cysteine?

Cysteine is found in many protein-rich foods including red meat, poultry, fish, dairy products like milk and cheese, eggs, seeds, nuts and leafy greens. You can also get cysteine in protein powder products that are mixed with milk or water and consumed as smoothies or milkshakes.
