A team of researchers from Japan are claiming that vitamin E supplements are linked to the development of osteoporosis.
Early stage studies on mice revealed that large doses of the vitamin caused their bone mass to reduce and their bones to thin.
It also went on to cause the development of osteoporosis.
The team – from Keio University – are now calling for more research to be carried out, investigating the effects of vitamin E supplements in humans.
Bad news for mice. This ties in to a 2008 study which delivered bad news for rats:
BACKGROUND AND AIMS:
A positive correlation between intake of antioxidants including vitamins E and C on bone mass has been established by a number of investigators. The present study was conducted to evaluate the extent to which higher doses of vitamin E than normal dose (75 IU per kg diet) can reverse bone loss in aged osteopenic orchidectomized male rats.
Overall, the findings of the present study suggest that supplemental doses of vitamin E do not increase BMD [bone mineral density] values in male rat model of osteoporosis. However, human studies are needed to confirm the population findings indicating that individuals with higher vitamin E intake have higher bone mass.
Muscle pulling on bone builds bone, so weight-bearing exercise builds denser, stronger bones. The more bone mass you build before age 25 or 30, the better off you will be during the years of gradual bone loss. Exercise can also help you maintain bone density later in life.
The best exercises for building bone are weight- or load-bearing exercises. These include weight-lifting, jogging, hiking, stair-climbing, step aerobics, dancing, racquet sports, and other activities that require your muscles to work against gravity. Swimming and simply walking, although good for cardiovascular fitness, are not the best exercises for building bone. Thirty minutes of weight-bearing exercise daily benefits not only your bones, but improves heart health, muscle strength, coordination, and balance. Those 30 minutes don't need to be done all at once; it's just as good for you to do 10 minutes at a time.
