My professor said that the reason the RDA is doubled is because vitamin supplement manufactures lobbied to keep it high.
The medications used to treat arthritis vary depending on the type of arthritis. Commonly used arthritis medications include: Analgesics. These medications help reduce pain, but have no effect on inflammation. Examples include acetaminophen (Tylenol, others), tramadol (Ultram, Ultracet, others) and narcotics containing oxycodone (Percocet, Oxycontin, others) or hydrocodone (Norco, Vicoprofen, others).
Over the counter medications are generally safe but they all have side effects and can interact with other medications that you are already taking. NSAIDS, or non-steroidal anti-inflammatory drugs, are one of the most effective treatments for arthritis. They help to relieve pain and swelling. However, they can cause stomach upset and sometimes can lead to ulcers. It is important to always take this class of medication with food.
