Guest guest Posted April 22, 2006 Report Share Posted April 22, 2006 Definitely, Phil! It must be the DL form for helping LDN. unitedviv wrote: Is there any difference between DL-Phenylalanine and L-Phenylalanine? Phil Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 22, 2006 Report Share Posted April 22, 2006 Phil Yes, there is a difference between these two amino acids. DL-phenylalanine contains BOTH the D form and the L form oh phenylalanine. Some people do not tolerate it well because of a conversion problem but get benefit from l-Tyrosine which is made in the body by DLPA.

Guest guest Posted April 23, 2006 Report Share Posted April 23, 2006 Do you know if the DL form is available in Australia? Also is it ok to take it with anti-depressants?

Guest guest Posted April 23, 2006 Report Share Posted April 23, 2006 I tried to find it here in Australia and finally found a place in Perth with it on their website so ordered two bottles. When it arrived however it was only the L form, not the DL form so I had to send it back. Conclusion I have come to is it is not available here (or may only be available on prescription). iherb.com where I get all my antioxidants from that are not available here or too expensive here have it so next time I put an order in (soon) I am going to get some DLP too - it's not very expensive but to order it alone would be impractical due to the shipping charges. If you are interested I could order some for you and that way the extra shipping charges will be very small. I don't know if it is OK to take with anti-depressants but I gather that with LDN and DLP you shouldn't need them. Since starting on LDN I have long ago weaned myself off anti-depressants.

Guest guest Posted April 23, 2006 Report Share Posted April 23, 2006 I just saw this post but wanted to add I bought this on the internet. At neurotransmitters b-calmed. There is a phone number on the site and I would recommend talking to the girl or at least email her. There are definate DO's and DONT'S per condition and she helps guide you to the product you need. Questions? Just ask, wendy. Da Costa <topazblue@...> wrote: Do you know if the DL form is available in Australia? Also is it ok to take it with anti-depressants?

Guest guest Posted January 4, 2009 Report Share Posted January 4, 2009 I received my custom aminio acids from Dr. Cliff Sheats and notice that they have a warning on the back that says, " Phenylketonurics- Contains Phenylalanine " . When I looked this up, it was not good. First of all, 50% of Aspartame contains this, and aspartame is poison in my opinion. There were also a couple of articles on the NIH website talking about the potential neurotoxicity of phenylalanine. Any info on this would be great. So far, not terribly impressed with my very expensive experience with Dr. Sheats. Thanks, Amy Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 4, 2009 Report Share Posted January 4, 2009 Diet Coke contains phenylalanine, a mild mood enhancer. That's why Diet Coke drinkers are so avid about their sodas. A former co-worker was a DC fan and started having seizures. Lost his driver license and everything. Then his father read where phenylalanine could cause siezures, so he stopped drinking the diet cokes and stopped having siezures. After a year he got his license back.

Guest guest Posted January 4, 2009 Report Share Posted January 4, 2009 Hi Mark, I don't know the content, but maybe you might want to contact Coke to ask about the Phenylalanine content. http://www.thecoca-colacompany.com/contactus/index.html http://www.thecoca-colacompany.com/contactus/cokefeedback/index.html The Coca-Cola Company P.O. Box 1734 Atlanta, GA 30301 USA You may also be interested in this: Nutritionists advise that Coca-Cola and other soft drinks can be harmful if consumed excessively, particularly to young children whose soft drink consumption competes with, rather than complements, a balanced diet. Studies have shown that regular soft drink users have a lower intake of calcium, magnesium, ascorbic acid, riboflavin, and vitamin A. http://en.wikipedia.org/wiki/Coca-Cola#Formula Those of us with CMT need our calcium and magnesium among others.

Guest guest Posted January 4, 2009 Report Share Posted January 4, 2009 Hi Mark,  The FDA's ADI (allowable daily intake) of Aspartame is the equivalent of about 20 - 12 oz cans of diet soda for a 150 lb man.  When setting an ADI amount, the FDA typically uses an amount 100 times less than what they really feel is safe, i.e. the amount of Aspartame in 200 cans of soda for a 150 lb man.  Phenylalanine, a component of Aspartame, is an amino acid that is also found in protein, like milk and meat products. When you consume animal-based protein, you are consuming phenylalanine.  According to the FDA, Aspartame has been studied for decades and to date, there have been no scientific studies that conclusively link it to cancer or any of the other diseases that many claim aspartame causes, including neurologic disorders.  http://www.ncbi.nlm.nih.gov/pubmed/17828671?ordinalpos=1 & itool=EntrezSystem2.PEn\ trez.Pubmed.Pubmed_ResultsPanel.Pubmed_DiscoveryPanel.Pubmed_Discovery_RA & linkpo\ s=3 & log$=relatedreviews & logdbfrom=pubmed  http://www.fda.gov/FDAC/features/1999/699_sugar.html  There are a small percentage of people with a genetic disorder, PKU, that prohibits the body from processing the amino acid, phenylalanine, properly. These people need to avoid it. A blood test can be taken to determine if a person has this genetic disorder. Also, pregnant women should avoid consuming Aspartame, if they have high levels of phenylalanine in their blood.  Nonetheless, there is still much wisdom in the centuries old adage, " All things in moderation " . And, just because research studies have been " inconclusive " , doesn't mean something is good for us.  Consuming 12 cans of soda is a lot and Aspartame isn't the only ingredient in diet soda. There's also carbonation, phosphoric acid, and caffeine. Each of these things can also have their own issues, especially when not consumed in moderation.  Health professionals that I've spoken with recommend limiting consumption to no more than 1-2 cans per day and then drinking it through a straw to help protect teeth.  Recommended low calorie substitutes include black coffee/tea (also in moderation) and water. To flavor water, add a slice of lemon or lime.  Quote Link to comment Share on other sites More sharing options...

Guest guest Posted January 5, 2009 Report Share Posted January 5, 2009 As a doctor, I can't let this go without comment. Phenylalanine is one of the many amino acids that are found in all proteins. The amino acids as a class are some of the most important molecules to sustain life. So, there is nothing inherently " bad " about phenylalanine. Just as with most substances (including water), consuming it in huge quantities can be dangerous. My grandmother gave me the best medical advice ever: " Everything in moderation, do " . When a " good " food is taken to excess or a " bad " food is strictly banned there may be hidden reprecussions down the road. The warning to phenylketonurics is not relevant to the rest of us. Phenylketonuria is an inherited disorder that disrupts the processing on this particular amino acid allowing toxic levels of a by-product to build up in the cells. It is extremely rare and in infants and children who are undiagnosed, a normal level of phenylalanine will cause mental retardation. Those of us who process it normally don't need to worry about phenylketonuria. BTW - to the guy who drinks 12 Cokes a day -- that ain't moderation! It would be better for you all around to cut it down significantly. Try some other beverages.... water? Dr. Holli Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 6, 2009 Report Share Posted January 6, 2009 If you have CMT, as most of you do, you should really do your research on these artificial sweeteners. A good friend of ours who is a well known author in France wrote a book called " Toxic " . It is all about the bad health effects of sweeteners such as aspartame and the corruption between the FDA and Monsanto, the company that made (still makes) aspartame. There are scientific studies showing rats that are given high doses of aspartame, developing brain tumors. You may say rats aren't human, but I don't want to be ingesting something that could potentially give me brain tumors. As CMTers, we are hoping that the same thing that happened to the rats with Vit C, will happen to us! Worth exploring if you are addicted to Diet drinks...and, it's worth noting that the FDA has just approved stevia for use in Diet Coke, so this will be changing soon. You will find Stevia popping up in alot of things. Stevia is a natural (plant source) sweetener...you just have to be careful what company you buy it from, because they use various means of producing the sweetener. Don't want anything processed chemically. Amy Hodge   Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 20, 2009 Report Share Posted January 20, 2009 Dr. Holli, I have always wondered about this. I get the most awful, pounding, splitting headaches when I consume aspartame. One can of diet soda is enough to send me to the couch for the rest of the day, and if I should bend over with this headache, well, I have considered that decapitation might be less painful! This happens to at least three other people I know, as well. Are we all phenylketonurics, or simply sensitive to the substance? Not that naming the problem would change it, I just thought that if it is such a rare condition, how do I know so many people with the same problem?

Guest guest Posted January 21, 2009 Report Share Posted January 21, 2009 Hi , I use to drink diet pop until one day I collapsed, and had been having awful night tremors. I finally put it together that it was the phenylalanine. Now if I drink anything with a sugar substitute I get tremors all night. I also have the same problems if I get any MSG in my food. I read an article that stated phenylalanine causes nerve damage... we should all stay away from it! Kay~Beautiful Oregon Coast Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 21, 2009 Report Share Posted January 21, 2009 Hi , After the standard disclaimer that I have never physically examined you and only have the brief information you've given me -- what you describe sounds like a classic migraine. Migraines can have many triggers and can be quite individual. I have heard anecdotally about aspartame being a trigger for some - have not heard of it being linked to phenylalanine, but that doesn't mean it can't be. You most certainly are not a phenylketonuric. People with this disease must be on a very strict diet, completely cutting out phenylalanine from birth or they will be severely developementally retarted. You couldn't possibly make it to adulthood with a typical diet without severe mental defecits. Another physical characteristic is very fine, brittle, blond hair. It's common to all PKU pts. (I don't know what you look like, but that might help you). Migraines, on the other hand are excedingly common. I get them too, my trigger is hormonal -- a little harder to avoid! Luckily, mine are very responsive to Excedrin Migraine formula. Not everyone is so lucky. It sounds like the potential for nerve damage from phenylalanine and the general warnings against aspartame as well as a probable migraine trigger for you all point to avoiding this artificial substitute for good old sugar. Consume the sugar in moderation and all should be fine! On a gut level, with my moderate knowlege of science and physiology, I tend to avoid all the " fat-free, sugar-free, food-free " substitutes that claim to make us more healthy. In my opinion the healthiest diets are cooked at home from easily recognizable ingredients. The more the syllables in the ingredient list, the less healthy. Have you ever microwaved that fat free cheese? It becomes permanantly polymerized to the plate. Wonder what it does inside your body?? That's just personal opinion, take it for what it's worth!
