Vitamin B-3 as niacin in larger than RDA doses will help induce sleep. Taking between 50 and 200 milligrams about 20 minutes before bedtime usually works best. The amount required varies a bit from one person to another. Ideally, you take the least amount that makes you the most sleepy. Expect to experience a brief niacin "flush" (like a hot flash or blushing sensation) which goes away in short time. The warm feeling is pleasant to most people, but may be avoided by simply taking less niacin at any one time. A bit of practice will tell you how much you need.
Are you taking niacin as a supplement, or are you taking peparations that contain niacin? You may be overdosing. Oddly, a typical sign of niacin overdose is the sensation of heat or burning in the face, and is called Niacin Flush. It can affect parts of the body other than the face. Either way, check what you are taking, and let your primary care physician know about the symptom. You may be overdoing other supplements without knowing it. Niacin Flush by itself isn't cause for alarm, but it can be very uncomfortable.
It's it safe to donate plasma and take niacin pills
None. It doesn't work and taking an OD of niacin is dangerous.
There is no Niacin OD. You can cause Liver and Kidney damage by taking too much though.
Possibly. There are other reasons as well, such as rosacea and effects of taking slow Niacin. You should have your blood pressure checked to be sure.
It is bad to take any drug after it expires. The effects of taking expired drugs can be quite drastic and your may need your stomach pumped you do so, Niacin is considered a supplement and not a drug. While the first responder is somewhat correct, the taking of expired niacin is not the most dangerous thing you could do. The greatest issue you have in this case is water absorption in the pill and a loss of potency. A month's supply of Niacin is under ten dollars from Amazon. I would recommend staying with the current pills to one's nearly so.
Yes. Milk thistle has very few interactions. On the other hand, the mechanism of niacin's beneficial actions aren't well understood, but they seem to involve how it is processed in the liver. So if I were taking milk thistle and niacin, I would be inclined to take them a few hours apart, so that the liver can deal with the niacin without the milk thistle interfering...
I heard that it can be born without an anus :S
I recommend talking to your healthcare provider or doctor before taking any medications. All medications have side effects and it needs to be discussed with your doctor before taking anything that could affect your current medications.
Some users experience tingling in the face and neck, similar to the sensation experienced when taking niacin. Also a change in breathing and heartbeat pattern are common but completely normal and safe.
One cocktail or a shot of liquor will intensify effects. Just one.
Drug tests are not easy to fool.
