niacine&long term effects.?
351356
The RDA for niacin is 14 mg for women and 16 mg for men. Specific disorders usually require higher doses. Megadoses can cause serious side effects, such as abdominal cramping, nausea, and vomiting; lightheadedness; ulcers; and skin rashes, flushing or itching. Liver damage is also a risk with long-term use of niacinamide and nicotinic acid. Inositol hexaniacinate in doses higher than 2,000 mg a day may have a blood-thinning effect.

I've been on the pill for 5 years... my gyno said there aren't negative long term effects.  Beats wanting to die from horrible cramps.

Please read below about some of the consequences of long-term laxative use before you decide to deal with your constipation this way.  These are things that can happen to anyone who uses laxatives long-term, not just people with eating disorders. Be careful.\n\n\nWhat are the Consequences? \n     Essentially, whether taken short term or long term, laxatives create and perpetuate the very problem they were intended to\ncorrect. \n     Laxatives induce constipation as the\ntissues become dried out, muscles become weak from lack of use, and the delicate nerves lining the colon become damaged. This damage slows intestinal motility and results in constipation. \n     With damage from long term laxative abuse, the colon may fail to function\nentirely. This is laxative dependency. \n     An individual who abuses laxatives may have diarrhea like stools in place of well formed stools.\n     Long term laxative abusers may\nexperience weight loss, hair loss, vomiting, abdominal pain, low energy, thirst, dry eyes, headaches, puffiness, mood swings, bone pain and suffer symptoms of dehydration. \n     With prolonged use of laxatives a\nnumber of serious problems may arise such as fluid and electrolyte imbalances, damage to other organs, and syndromes resembling colitis.

Niacin can be quite effective for lowering blood lipids, but it is best attempted under the guidance of a physician, because very high doses may cause liver damage.  You could probably self-treat with 100-200mg. daily.  You will experience a flushing sensation, your skin will get quite red and tingly and you may even notice some slight swelling in the facial area.  This is only temporary, lasting a few minutes.  If you become nauseated, you have taken too high of a dose, and will need to make future adjustments.

There are no permanent to my knowledge, other than you'll be a hypocritical parent someday.  Short term effects... cotton mouth, short term memory loss, finding stupid things hilarious (Blue Beard the Pirate or the Tick) and couch potatoitis.  How to combat the effects drink Arizona Green Ice Tea or Mountain Dew and get outdoors.\n\n(All my high school friends smoked, but I never did.  My mom used to smoke so it was a form of rebellion.)  : )

I have been searching and all the literature and the side effects listed are all short term, there is no mention of long term effects.  I would think that the experts know very little about this as Ritalin is a relatively new drug.\nYou have been on some pretty serious drugs in a short time frame, maybe its the combination rather than just one drug which has caused your problems.\nI feel for you, its rotten on top of the problems you have already had.  I hope you find a satisfactory answer to your question...good luck x

Here's a good page on L-Tyrosine and it shows the full metabolic pathway.  Side effects are from large doses. I'd say try it, go slow and note how you feel. I'd also recommend a book: The Edge Effect: Achieve Total Health and Longevity with the Balanced Brain Advantage. He has a complete questionnaire that helps you pinpoint which of the four main neuro chemicals you lack: serotonin, dopamine, GABA or acytlcholine. Then he tells you how to increase (nutritional, exercises etc.)\n\n- Peace

There is very little risk of overdosing on this product.  The only B-vitamins with any serious potential for toxicity are niacin and B6.  \n\nIn very high doses used for controlling cholesterol levels, and taken for very long periods of time, there is a risk of liver toxicity with niacin (but not niacinamide).\n\nAgain, in very high doses (300 mg/day for months to years) of B6 for a few people has apparently caused a reversible peripheral neuropathy.\n\nThe doses in this product would be safe at much higher levels than you are taking.  If you feel your panic attacks are helped by these nutrients you can safely take more to see if you improve further.\n\nIt is important to recognize that B-vitamins function as cofactors for many enzymes.  Sometimes these enzymes are genetically 'defective' and require much, much higher levels of the associated B-vitamin cofactor to properly activate the enzyme.  There are over 50 known genetic diseases that are treated with extremely high doses of the proper B-vitamin to activate the defective enzyme.  It is unknown how many people have an 'intermediate' level of function of an enzyme that may also respond to high doses of the vitamin cofactor, but it is likely that such situations are common.  For example, an important enzyme known as MTHFR (methylene tetrahydrofolate reductase) requires B2 as its cofactor. 10 -20% of the population has a genetic 'variant' of this enzyme that requires much higher doses of B2 for proper activity of the enzyme.  This particular issue plays an important role in the risk for many chronic diseases such as cancer and heart disease.\n\nI realize I have kind of run on a bit here.  But you asked a very important question and sadly, many health professionals (i.e. medical doctors) do not know this basic biochemistry and therefore believe the false concept that 'high doses of b-vitamins just make expensive urine'.\n\nBest wishes and good luck.\n\nP.S.  Given your problem with panic attacks, you may also want to try taking some fish oil  supplements.  These provide important omega-3 fatty acids that are critical for the healthy functioning of your cell's membranes and also play a vital role in reducing inflammation.\nA good (not Centrum, One-D-Day or other 'Junk' supplements) multi-vitamin/mineral supplement may also be appropriate for you.

I believe that the vitamin niacin acts as a coenzyme in the electron transport system of cellular respiration in aerobes. This system is a major producer of ATP . A niacin defficiency would therefore cause an individual to experience early fatigue during exertion.

As far as I know, there's no documented adverse creatine side effects - only desirable side effects of creatine. I've used it personally with great results.\n\nExtensive experiments have been done to test creatine side effects on humans, and the only documented adverse effect of creatine supplementation is an increase in body mass.\n\nAlso take caution as there are no long term studies on high dosage effects on creatine use. So its recommended that you follow the instructions on the label and don't over do it. \n\nAlways use as directed, at your own risk and always weight train safely.\n\nThe National Strength and Conditioning Association has several scientific publications on creatine.\nhttp://nsca-lift.org/

There is a lot of information available on the possible side effects of this drug.  I know someone personally that took it for a fertility issue, and had no side effects.\n\nUse this link below:\n\nhttp://health.yahoo.com/drug/d03807a1

I have had great results with it.  I started taking it about 25 years ago as a result of gum disease.  I was told I would lose my teeth within a few years and I still have my teeth.  I also understand that it is can be used as a possible preventative for some heart problems.  Common sense dictates that we need to contribute (be pro-active) with the physical care piece rather than just relying on medication for results.

I have been taking beyetta 10mg. for over 6 months.  I have never had any side effects.  I take it before breakfast and dinner.  They say that you need to be sure not to take it after eating.  There is a blog on beyetta.  I looked into it before starting.  There were alot of people having problems with it.  I googled beyetta and found it that way.  Hope things work out for you.  They say it's suppose to control the weight gain from insulin.  It has stopped my weight gain but has not helped me any in reducing.\n\nAgain, I hope it works out ok and don't forget to look for the blog.

In low single doses (200 to 400 mg) and daily doses of up to 1,200 mg the incidence of side effects is low. However, in patients treated on a long-term basis with more than 1,200 mg daily discontinuation rates are as high as 10 to 15%.This includes smoking, injecting or any form of absorption.\n\nCommon adverse effects include: nausea, dyspepsia, gastrointestinal ulceration/bleeding, raised liver enzymes, diarrhoea, headache, dizziness, salt and fluid retention, hypertension.\n\nInfrequent adverse effects include: oesophageal ulceration, heart failure, hyperkalaemia, renal impairment, confusion, bronchospasm, rash
