Should I take eye vitamins? What’s AREDS2?

QUESTION: Should I take eye vitamins? What’s AREDS2?

(Updated October 2022)

This only applies to those with Age-related macular degeneration (AMD or ARMD) not any other form of macular degeneration (MD).

This is NOT medical advice. It is information for you to use:
– to do your own research
– to ask questions of your eye specialist
– to ask questions of your medical doctor.

The Basics

1. What is AREDS and AREDS2?

They are NOT brand names.

AREDS stands for Age-Related Eye Disease Study. There were 2 studies: AREDS results released in 2001; AREDS2 results released in 2013.

2. What was the purpose of the studies?

The purpose of these studies was to see if a specific combination of vitamins and minerals would slow the progression of AMD to the advanced forms of wet or advanced dry/geographic atrophy. They were both conducted by the US National Insititute of Health (NIH) National Eye Institute (NEI). The Bausch & Lomb company provided the formulations & financially supported both studies. Click here to read the information provided by the NIH NEI about AREDS and AREDS2.

3. What were the formulations?

Both studies used 500 mg of Vitamin C and 400 IUs of Vitamin E. In the first study (AREDS or AREDS1), they used 15 mg of beta carotene, a carotenoid. When research showed a connection between beta carotene and lung cancer in smokers and former smokers, beta carotene was removed in AREDS2 and replaced with 2 other carotenoids: 10 mg of lutein and 2 mg of zeaxanthin.

Both studies included zinc: AREDS used 80 mg of zinc. In AREDS2, there were 2 groups, one with 80 mg of zinc and a second with 25 mg of zinc. Both groups had the same posotive results, but because AREDS2 did not have a true placebo group, the NEI says that the ‘gold standard’ for the formulation includes 80 mg of zinc. Because zinc removes copper from the body, copper was included: 2 mg of copper with 80 mg of zinc, 1-1.2 mgs of copper with 25 mg of zinc.

Bausch & Lomb has the patent to both the AREDS & the AREDS2 formulations with 80 mg of zinc. Because of that, their PreserVision products are the only ones with 80 mg of zinc. After AREDS2 results were published in 2013, many companies marketed their ‘AREDS2-based’ products with the same formulation but with 25 mg of zinc.

4. Who in the studies did they help?

They were effective in slowing down the progression to wet AMD (but not geographic atrophy) for some people with:

a) intermediate dry AMD.
b) wet AMD in one eye but not the other.

5. What about the rest: those who do not have AMD, have early AMD, have wet AMD in both eyes or have another form of macular degeneration such as Myopic Macular Degeneration (MMD) or Stargardt’s Disease (SD).

a) They were NOT tested on those who do not have AMD or have wet in both eyes.

b) They were tested on those with early AMD in AREDS but not AREDS2 because they showed NO benefit in the 6+ years of the study.

c) They’ve NOT been tested on those with another form of macular degeneration.

6. What’s the harm taking them if they weren’t tested on people like me?

Some of the ingredients are high doses. There’s been no research on whether taking them if you don’t need them is safe or effective. Would you take a blood-pressure-lowering medication if you did not have high blood pressure?

7.  What is the controversy about zinc in AREDS and AREDS2?

A 2018 study using the genetic profiles of some of the participants of the AREDS study (the first one where 80 mg was used) found that for 15% of the people with a specific genetic makeup (I call it being ‘zinc sensitive’), their AMD progressed faster than those in the study with a different genetic makeup.

8. I’ve heard not everyone agrees with those findings. What’s up with that?

This finding has been disputed by the NIH NEI researchers involved in the AREDS and AREDS2 research. The NEI, some eye specialists, and the AAO (American Academy of Ophthalmologists) take that side and say that genetic testing is NOT necessary because there is no difference in effectiveness of the 80mg of zinc based on genetics.

The opposite view is taken by the researchers involved in the 2018 and prior research. The genetic testing they used in that study and previous studies is available through your retinal specialist by the ArcticDX company.

9. My stomach hurts when I take PreserVision. Why would that happen?

The National Institute of Health’s Office of Dietary Supplements says that the upper tolerable limit of zinc is 40 mg.  According to their page, some of the signs of too much zinc are “nausea, dizziness, headaches, upset stomach, vomiting, and loss of appetite. If you take too much zinc for a long time, you could have problems such as lower immunity, low levels of HDL (“good”) cholesterol, and low copper levels. Taking very high doses of supplemental zinc can reduce your body’s absorption of magnesium.”

Piles of Articles

Long, holiday weekend. I am on the second day of four and have gotten pretty much nothing done. Oh, well. Procrastination is us.

Be that as it may, Happy Fourth of July whenever you may be!

Part of the ‘straightening up’ task for me is going through piles of articles I have found interesting and printed out. That word is actually PILES.

Just rediscovered one – Update on Genetics and Age-Related Macular Degeneration by Jerome Dunaierf – that has some good stuff in it. Did you know people with a parent with AMD have DOUBLE the risk of getting the disease? Make sure the kids get their eye exams!

Jerome talks about the complement immune system and does a nice job – much clearer and nowhere near as fanciful – in describing how the ‘friendly fire’ bit works. He shared the proteins that activate the complement system have been found around drusen. (Maybe a demented garbage men analogy would be better? Coming for the trash but hauling away the house?)

Jerome also talks about the ARMS2/HTRA genes. Enticing and mysterious those. No true clue what they do but we with AMD often have certain variants of them.

Other genes that seem to be somehow in the mix include genes that code for collagen formation, cholesterol formation and cell signaling. You might not realize it but the chemical ‘chatter’ going on in our bodies is deafening! Eavesdrop on that and we could intervene in amazing ways.

Jerome agrees with me lampalizumab will open up a HUGE market for genetic testing. (Probably the reason I kinda like Jerome). He shared it is now possible to sequence an entire human genome in a few days. The cost? About $1,000.

Wow. Have your code read and know exactly which drug is going to work on you. How far in the future before genetic sequencing becomes a requirement for getting health insurance? Ethical nightmare that.

And a little filler here: Pubmed published an abstract on a meta analysis of 10 trials about the risks and benefits of aspirin. Bottom line was this: aspirin can keep those of us with cardiovascular problems alive. Proven. Aspirin might, maybe, could have a negative effect on your AMD. The authors, Small, Garabetian, and Shava decided most of us would want to be alive. Their advice was to take your aspirin.

OK. A few more things off the pile. Time to wander off to something else. Maybe some housework. Gasp!

I am staying home from yoga today. Self diagnosis of rotator cuff tendinitis. Doctor’s appointment next week by which time I will not only have diagnosed but also treated myself!

My yogini is digging out a ‘no arms’ practice she found so I can try that tomorrow. Movement continues to be important to – and for! – me. Where there is a will, there often is a way.

That is what is happening here. Hope you are all doing well. Bye!

June 2023 There’s an announcement that since Sue has not written any new journal pages for some time, the site has been archived until we can decide if the work necessary to make sure all information is accurate and up-to-date can be made. In the meantime, you’ll get some pages ‘not found’ or ‘private’ until that decision has been made. The emphasis for several years has been on the Facebook group.

2/14/2022 Because of the rapid and constant growth of our Facebook group, I cannot keep this list updated.  I have a large amount of information available in the Facebook group in Guides which are like chapters in a book or lessons in a course. Plus, in 3 years, the amount of information in the posts and comments is quite substantial. I recommend that you join us there where you can get the information and the support to help you in your journey.  Thanks for understanding. Hope to see you there! Lin/Linda…
I’ve added some pages from that group that might be of interest to you.

What is Stargardt’s Disease?

Also called Stargardt’s Disease (SD) or Stargardt Macular Dystrophy (SMD) or Juvenile Macular Degeneration (JMD), it’s an inherited, juvenile macular degeneration. The progressive vision loss associated with Stargardt disease is caused by the death of photoreceptor cells in the central portion of the retina called the macula.

Risk factors

Age

  • Age is a large factor but can start earlier
  • Much less common are several hereditary forms of macular degeneration, which usually affect children or teenagers. Collectively, they are called Juvenile Macular Degeneration. They include Best’s Disease, Stargardt’s Disease, Sorsby’s Disease and some others.  See Stargard’s Disease section above.

Diet/nutrition (working on this section)

  • diet low in various nutrients & high in others have been linked to AMD.
  • See Nutrition and Vitamins/Supplements under Self-care/self-maintenance below.

Race

Gender

  • AMD more common in women perhaps because women live longer than men

Uncontrolled high blood pressure

Uncontrolled high cholesterol

Smoking

Blue Light

Eye Color

Aspirin & other medications

Other possible causes

  • Biological Process in Wet AMD – some evidence that the photoreceptors are starved by the lack of food (oxygen & nutrients in the blood) and the growth of blood vessels is to compensate for that.
