Is it necessary to occasionally pause taking glucosamine?

Question:
I’ve been using your glucosamine for several years. Now I’ve met a few people who use their local (Portuguese) glucosamine and their pharmacist has told them to stop taking it at least once a year. Does the same apply to your product? I couldn’t find anything about it on the internet.[glucosamine-rechts]

Answer:
We don’t know of any indications that could infer ceasing the use of glucosamine. Long term studies have been conducted for 2 and 3 years. Glucosamine is safe in that time period. Epidemiological studies have even found that people who use glucosamine have a slightly reduced mortality rate and a lesser chance to get cancer.

A recent study in mice shows that these animals live longer when they get glucosamine administered. These researchers published their findings in the renowned Nature magazine. The researchers suspect based on the presumed mechanism (influencing the carbohydrate metabolism) that glucosamine extends the life of humans.
Converted to human years, the mice received glucosamine from their 65 year. These mice lived an average of at least 7 years longer than the control group (also converted into ‘human years’).
