What is melanin?
Melanin is a pigment naturally present in the human body, responsible for colouring the skin, hair and eyes. It is produced by cells called "melanocytes", located in the epidermis and dermis, the upper layers of the skin.
origin
Melanin is produced from the amino acid tyrosine, which is present in the foods we eat. It is also produced naturally by the body through a complex biochemical process. This process begins with tyrosine, which is then transformed into dopaquinone and converted into melanin by an enzyme called tyrosinase.
The benefits of melanin
Melanin has many health benefits and plays an important role in maintaining the body's balance. Here are just a few of the benefits:
Protection against UV rays
Melanin protects the skin from damage caused by the sun's harmful UV rays. By absorbing UV rays, melanin protects our DNA from damage and helps prevent skin cancer.
Production of vitamin D
Melanin plays a key role in the production of vitamin D by the skin. By absorbing the sun's UVB rays, melanin stimulates the production of vitamin D, which is essential for healthy bones and the immune system.
Protection against free radicals
Melanin has antioxidant properties that help protect cells from damage caused by free radicals. Free radicals can damage cells and contribute to diseases such as cancer and cardiovascular disease.
Anti-ageing effect
Melanin also has an anti-ageing effect, as it protects the skin from damage caused by free radicals, which can accelerate the ageing process. It also helps to keep the skin hydrated and prevent fine lines and wrinkles.
Boosting the immune system
Melanin has been linked to an increase in immune activity, which can help strengthen the immune system, prevent disease and speed recovery from infection or illness.
Use as a food supplement
Melanin is available on the market in the form of food supplements. These supplements are generally made from melanin extracted from natural sources such as fish or plant skin.
Skin improvement
By taking melanin as a dietary supplement, it is possible to reduce the damage caused by UV rays, improve skin hydration and elasticity and prevent premature ageing. It can also help treat skin problems such as hyperpigmentation and acne.
Skin cancer prevention
By protecting the skin from damage caused by UV rays, melanin can potentially help prevent skin cancer. However, it is important to note that melanin supplements should not be used as the only method of protection against the sun and that it is always essential to use appropriate sun protection.
Regulation of pigmentation
Melanin can also help regulate the production of natural melanin in the skin, which can be beneficial for people with pigmentation problems such as vitiligo or age spots.
Improved mental health and sleep
Some melanin supplements also claim to improve mental health and sleep. Melanin plays an important role in regulating the sleep-wake cycle and has calming effects on the brain. However, it is important to note that further studies are needed to confirm these benefits.
Precautions and side effects
Although melanin supplements are generally considered safe, it is important to consult a doctor before taking them, especially if you have health problems or are taking other medications. Some possible side effects include nausea, headaches, gastrointestinal problems, increased melanin production in the skin and an increased risk of blood clots.
It is also important not to exceed the recommended dose and to follow the manufacturer's instructions on dosage and duration of use.
Conclusion
Melanin is an essential pigment for general health and well-being. It has numerous benefits for the skin, the immune system and sleep regulation. As a dietary supplement, it can be beneficial for improving skin health and preventing disease. However, it is important to consult a doctor before starting to take melanin supplements and always follow the manufacturer's instructions to avoid any unwanted side effects.
