How to interpret 23andme data for supplements

I don't think anyone here can answer this. If you are lucky enough to find a MD who specializes in genetic holistic medicine that would be the person but they are probably pretty rare. Of course there are naturopaths who will say they do this but take it with a grain of salt.

The "science" of using DNA results to pinpoint treatments is very very new and controversial.
The most informed poster here (who is not here much any more) is Pathogen Killer.

What I did after getting my results from 23andme (before they shut off giving health reports) is to be aware of what the latest science says about my potential weaknesses which included diabetes, celiac and Alzheimers. But honestly it's all the same: eat a balanced diet including lots of veggies, exercise often, etc.

First you need to research the gene mutations that promethease claims are good,bad or effect medications. They gave me a very questionable bad finding regarding a hereditary disease. Using google I was able to determine that the near certain life threatening disease I have is in fact a 1% chance of mild symptoms if I had some additional risk factors that I don't have. What they did was condense and simplify a complicated condition that is not fully understood involving 3 gene mutations into 3 sentences.

The more common problems I was alerted to in the expandable good, bad, interesting, drugs report did contain some diet and supplement recommendations and they were brief but fairly accurate when I checked other sources. Do a google search with the condition or drug with and without the gene mutation (these are a code like H56D etc).

I mostly found out things I already knew were a issue. The exception was that I don't have both mutations connected Alzheimer's which I am pretty happy to know. My dad's side is plagued by the disease and I am sure my dad has both because I got one copy from him.

I received a minor warning on crohns but nothing on UC. Not sure that isn't just because of my Northern European ancestry. I am sure my high melanoma risk was simply my ethnic heritage and light skin.

Really puzzled why more people on this board haven't signed up for this free test. I could really find out some useful stuff if thousands of UCers signed up.
