Beyond lifestyle adjustments, AMD supplements make a difference. Here, we’ll walk you through some supplements that may offer benefits for AMD, so you can make informed choices about what to include in your health routine.
Understanding AMD and the role of supplements
AMD primarily affects the macula, a small part of the retina responsible for sharp, central vision. This can impact your ability to see fine details, read, drive, and recognise faces.
While lifestyle factors, such as avoiding smoking and following a balanced diet, play a role in managing AMD, certain supplements may provide additional support.
Research shows that specific vitamins and minerals can help slow the progression of AMD, especially when used in targeted combinations. Below, we’ll explore key supplements known for their potential benefits in AMD.
Essential vitamins and minerals for AMD
Vitamin C
Vitamin C is a powerful antioxidant that helps protect cells in the retina from damage caused by free radicals. Research, especially the Age-Related Eye Disease Study (AREDS), highlights that vitamin C, in combination with other antioxidants and minerals, may help slow AMD progression.
Since our bodies don’t produce vitamin C naturally, incorporating it into your diet through supplements or foods like oranges, strawberries, and bell peppers can be beneficial.
Vitamin E
Vitamin E is another antioxidant essential for eye health. It helps combat oxidative stress, a major contributor to AMD. Studies suggest that vitamin E, combined with other key nutrients, may support macular health and delay vision deterioration.
Common food sources include almonds, sunflower seeds, and avocados, but a supplement can help ensure you’re getting a consistent, effective amount.
Zinc
Zinc is a mineral vital for eye health and plays a significant role in transporting vitamin A from the liver to the retina. It supports the immune system and may help reduce the risk of AMD progressing.
Zinc is especially beneficial in the forms found in seafood, red meat, and nuts. However, too much zinc can interfere with copper levels, which leads us to the next supplement.
Copper
When you take zinc supplements over a prolonged period, you may risk copper deficiency. This is why copper is typically included in eye health formulations containing zinc.
Copper supports cellular function and plays a role in maintaining the health of connective tissue in the eyes. It’s often found in small amounts in nuts, seeds, and shellfish.
Protective carotenoids: Lutein and zeaxanthin
Lutein and Zeaxanthin
Lutein and zeaxanthin are naturally occurring pigments in the retina that help filter harmful blue light and protect the macula from damage. These carotenoids can’t be produced by your body, so getting them through diet or supplements is essential.
Spinach, kale, and other leafy greens are excellent sources of lutein and zeaxanthin. Studies suggest that these carotenoids, when taken in combination, can help protect your vision and may slow AMD’s progression.
Omega-3 fatty acids for retinal health
Omega-3 fatty acids (DHA and EPA)
Omega-3 fatty acids, primarily DHA and EPA, are known for their anti-inflammatory properties and are crucial for the health of retinal cells. Research shows that these fatty acids may lower the risk of AMD in those who consume fish regularly.
For those who don’t get enough omega-3 from food, fish oil supplements or algae-based omega-3 supplements are viable alternatives.
Additional supplements for eye health
Beta-carotene
Beta-carotene, a precursor to vitamin A, supports eye health but may not be suitable for everyone. In smokers, beta-carotene supplements are often avoided due to potential health risks.
Non-smokers, however, may find it beneficial as it’s a potent antioxidant supporting general eye health. Carrots, sweet potatoes, and pumpkin are rich in beta-carotene.
Bilberry extract
Bilberry extract is known for its potential benefits in improving blood flow to the eyes, which may support retinal health. Though research on its specific effect on AMD is still limited, bilberry’s antioxidant properties may provide some protection to retinal cells.
Grape seed extract
Grape seed extract contains antioxidants that may protect retinal cells from damage. This supplement is still under research for its direct impact on AMD, but its general benefits for blood vessel health may contribute positively to overall eye health.
Curcumin
Curcumin, the active compound in turmeric, has shown promise in various areas of health due to its anti-inflammatory properties. While more research is needed to understand its impact on AMD specifically, curcumin’s potential to reduce inflammation could offer some support to those managing eye conditions.
How to choose the right supplements
If you’re considering adding supplements to your regimen, it’s essential to consult with a healthcare provider to tailor the right approach for you.
They can help you balance these nutrients effectively, especially since some, like zinc and copper, interact with each other.
You may also consider supplements formulated specifically for eye health, such as those based on the AREDS or AREDS2 studies, which combine these nutrients in amounts shown to benefit those with AMD.
Practical tips for incorporating supplements
- Check dosage recommendations: Follow dosage guidelines to avoid over-supplementing. More isn’t always better, especially with minerals like zinc.
- Combine with a healthy diet: Supplements work best as part of a balanced diet rich in fruits, vegetables, and omega-3 fatty acids.
- Consistency is key: Regular supplementation, combined with healthy habits, may offer the best support for slowing AMD progression.
- Avoid high beta-carotene if you smoke: Smokers should steer clear of beta-carotene and instead look for formulations that use lutein and zeaxanthin.
Final notes
AMD can be challenging to manage, but supplements offer a proactive approach to support eye health.
With the right mix of nutrients, a balanced diet, and regular check-ups with your eye specialist, you can take positive steps toward managing AMD effectively.
