AMD and Stroke

Clinical studies reported to the scientific staff at Biosyntrx have indicated that the antioxidants and phytochemicals in Macula Complete may be effective in slowing down or stopping the progress of early-stage age-related macular degeneration, an eye disorder that gradually destroys central vision. Now it appears that these same formula components may be effective in reducing stroke risk.

A recent study from the University of Melbourne, Australia showed that among 10,405 adults ages 49 to 73, those individuals with early-stage AMD were 87% more likely to suffer a stroke over a ten year period than those without AMD. The likelihood of other risk factors, such as smoking and hypertension increasing stroke risk were also considered. The conclusion: anyone diagnosed with AMD should also be monitored for stroke risk factors, and anything that may reduce AMD risk or progress may also prove to lower the risk of stroke.

You forgot to mention which nutrients in Macula Complete are effective in lowering the risk of stroke?

Spencer Thornton, M.D. said...

In general, the nutrients that support optimal retinal health also support brain circulation. Several have been cited as supporting optimal circulatory health, especially choline, zeaxanthin, ginkgo, lipoic acid, acetyl-L-carnitine and zinc in addition to the B vitamins and CoQ-10.
Of course we assume that you are aware of the importance of fish oil consumption daily for its DHA content.

I don't understand. Isn't fish better than fish oil, and why did you mention DHA and not EPA.

Spencer Thornton, M.D. said...

Macula User, you are certainly right, fish is better than fish oil, but how many Americans eat fish every day? Most prefer variety in their diets. That is why we recommend taking fish oil (like ZoOmega-3) on the days you don't eat fish.
Good question about DHA and EPA. A number of studies mention DHA as an important player in brain health; more significant than EPA.

The folic acid in your Macula Complete formula has also been credited with maintaining brain health and reducing stroke risk. I just read an article in the August 13 issue of U.S. News &World report (page 44-45) that "Folic acid may reduce stroke risk and, in people with ample vitamin B12, may guard against cognitive impairment." I note that your formula contains the right amount (800 mcg). Not too much, not too little.

I don't understand the last comment. Not too much, not too little compared to what!

Folate deficiency and byperhomocysteinemia are proving to be prevalent in elderly post-stroke patients and these two conditions have been suggested in a number of studies to be independently associated with the development of brain atrophy.

However, it's important to remember that efficient cysteine metabolism is dependent on optimal levels of folate, Vitamin B12 AND vitamin B6. Deficiency in any of these B vitamins can cause elevated levels of homocysteine in some people-apparently increasing the risk of stroke in the elderly if the new science is right.

Maggie, it has been pointed out (see the US News article mentioned earlier) that fortified foods add 128 micrograms of folic acid, on average, to a woman's daily intake. The feeling of most researchers now is that one should not take more than 1,000 micrograms per day. Allowing for that included in manufactured foods, Xiaobin Wang, of Children's Memorial Hospital in Chicago believes that taking 400 to 800 micrograms daily is often warrented for preventing stroke. The massive doses recommended by some does not seem justified.
