Preventing age related macular degeneration


Vita LuTein Complex®

Age-related macular degeneration (AMD) is a common eye condition that affects millions of people worldwide, particularly those over the age of 50. The good news is that there are several ways to reduce the risk of developing AMD, and one of the most clinically proven methods is through the use of lutein and zeaxanthin.

AMD is a progressive eye disease that primarily affects the macula, the central part of the retina responsible for sharp central vision. As we age, the macula can deteriorate, leading to vision loss and potentially blindness. There are two main types of AMD: dry AMD and wet AMD. Dry AMD is the most common form, characterised by the gradual breakdown of the macular tissues, while wet AMD involves the growth of abnormal blood vessels beneath the macula.

The Role of Lutein and Zeaxanthin

Lutein and zeaxanthin are two naturally occurring carotenoids found in high concentrations in the macula. These antioxidants are known for their ability to absorb harmful high-energy light waves, such as ultraviolet rays and blue light, before they can damage the macular cells. Additionally, lutein and zeaxanthin act as antioxidants, helping to neutralise free radicals in the eye.

The Clinical Evidence

Numerous clinical studies have demonstrated the benefits of lutein and zeaxanthin in reducing the risk of AMD:

  1. AREDS2 Study: The Age-Related Eye Disease Study 2 (AREDS2) conducted by the National Eye Institute found that a combination of lutein and zeaxanthin, along with other essential vitamins and minerals, reduced the risk of developing advanced AMD by 18% in high-risk individuals.
  2. Blue Mountains Eye Study: This long-term study discovered that people with the highest dietary intake of lutein and zeaxanthin had a significantly lower risk of developing AMD compared to those with lower intake levels.
  3. Carotenoids in Age-Related Maculopathy Italian Study (CARMIS): This study concluded that a higher intake of lutein and zeaxanthin was associated with a reduced risk of developing both early and late-stage AMD.

The Protective Mechanism

Lutein and zeaxanthin protect the eyes from AMD through various mechanisms:

  1. Filtering harmful light: By absorbing blue light and ultraviolet rays, these carotenoids shield the macula from the damage caused by these high-energy light waves.
  2. Antioxidant properties: Lutein and zeaxanthin help combat oxidative stress in the eye, reducing the risk of cellular damage.
  3. Reducing inflammation: These antioxidants may also have anti-inflammatory effects, which can be beneficial in preventing AMD progression.

Incorporating Lutein and Zeaxanthin into Your Diet

You can naturally increase your intake of lutein and zeaxanthin by including the following foods in your diet:

  1. Leafy green vegetables: Spinach, kale, collard greens, and Swiss chard are rich sources of these carotenoids.
  2. Corn: Yellow corn contains significant amounts of zeaxanthin.
  3. Eggs: The yolks of eggs also contain lutein and zeaxanthin.
  4. Supplements: Consider taking Vita LuTein Complex® supplements as recommended by eye care professionals.

Age-related macular degeneration is a common and potentially devastating eye condition that primarily affects older adults. Fortunately, the inclusion of lutein and zeaxanthin in your diet or as supplements can significantly reduce the risk of developing AMD, as supported by clinical evidence. These antioxidants offer protection against harmful light, oxidative stress, and inflammation, contributing to overall eye health and preventing vision loss. Make sure to consult with your healthcare provider or eye specialist before making any dietary or supplement changes, especially if you have existing eye conditions or concerns. By taking proactive steps to safeguard your vision, you can enjoy a brighter, clearer future for your eyes.
