One thing to keep in mind when deciding on how much glucosamine to use is the purity of your supplement. Glucosamine hydrochloride is about 99% pure , while glucosamine sulfate is about 75% pure. When you choose a supplement, check to see how much active ingredient it contains.
For example: say one pill from product A contains 1000 mg of glucosamine sulfate, and product B contains 1000 mg of total glucosamine. Product B should have 1000 mg, regardless of whether it’s in the form of hydrochloride or sulfate; product A will only contain 75% of 1000 mg, or 750 mg of total glucosamine.
Sometimes cheaper brands will try to get away with tricks like this. The FDA doesn’t monitor nutritional supplements, so make sure to take a high-quality product and find out exactly how much glucosamine is actually in it.
Glucosamine is found in healthy cartilage, and people take it to help deal with symptoms related to their joints. For example, pain, swelling, or inflammation due to rheumatoid arthritis or osteoarthritis. Personally, I have also found that supplementing with glucosamine eases some of the “creaky” feeling I get in my own joints from time to time.
Some people prefer to use glucosamine rather than pain relievers because they believe that it may help them to regrow more cartilage. Studies have not proved this effect of supplemental glucosamine. So, many patients take it in addition to their other medications.
How Should I Take Glucosamine?
When taking glucosamine, try to break it up into multiple doses. Your body can only absorb so much, so by taking smaller doses multiple times a day, you’ll help to ensure that your body actually uses the glucosamine you ingest. After all, it’s an expensive enough supplement, so anything you can do to get more bang for your buck is helpful.
How Much Is Enough?
Usually, people take 1,500 mg of glucosamine a day, broken up into three doses of 500 mg each. Some have also recommended 20 mg per kilogram of body weight. If you try 1,5000 mg per day and it works for you, you can try to decreasing the amount to 1000 mg, in order to lessen any side effects.
