Doctor's Best Lutein, 20 mg, Supports Eye Health & Performance, Non-GMO, Gluten Free 180 Softgels

Need to use it for a couple of months to know how well it works

Necessary items to keep eyesight.

I have been using lutein since I was 30. Keeps your eyes healthy and delays eye aging. Highly recommended!

This supplement contains natural extracts from marigold flowers. Extracts are readily absorbed by the body & deliver results. I like the ratio of Lutein (20mg) to Zeaxanthin (4mg). I take a supplement to fill dietary gaps. It's hard to get enough of Lutein & especially Zeaxanthin through diet alone.

I started taking this as a way to mitigate possible skin damage (I use a sperti UV-B Vitamin D lamp daily) and lutein has been shown to reduce photo-aging and photo-carcinogenesis in chronically UVB-irradiated skin. I cycle this supplement one month on / one month off, and each time after about 7 days into a new cycle, I noticed that I could type faster. Awesome. I looked for research to support this and found an article indicating an effect on visual-motor abilities and psychomotor speed concluding that "Accumulating evidence has shown that LZ may influence various aspects of brain function ranging from visual-motor to executive functions".I also have IBS-D, this gives me zero side effects.Update Aug 2019:I feel like I can think much more clearly and quickly since taking this. I started looking at evidence for cognitive effects (beyond visual-motor) of lutein, and there's actually tons out there!! It's apparently now referred to as a nootropic. Certainly feels like it, and with no downside at all. My brain just feels younger! Here's an example of what I found in studies: "Higher plasma lutein and zeaxanthin were associated with better scores across the domains of cognition, memory, and executive function" "Lutein preferentially accumulates in the human brain across multiple life stages." "Among the carotenoids, brain lutein content was the most consistently related to cognitive test scores".Now that I'm looking more closely at the product description, it says it right there: " Preliminary studies suggest they can enhance brain functions.".This has been a fantastic supplement. My highest recommendation.

Started a few weeks ago and vision appears crisper. Moreover, might be helping long term dry eyes also. Understand many good benefits of this combo esp for older folks like myself. Doctors Best makes good products.

Works really well on my dry eyes. I have been buying this product for years.

We loved our first bottle, great product. This was a re-order. We just opened them and the pills obviously melted during shipment. I can't pry them apart with a knife. I tried to contact amazon customer support but all I can find is info that these cannot be returned. I don't want to return them, I want amazon to replace them. I will need to find a different source.AI customer service is horrible. Amazon needs to bring back people to staff a real customer support service.
