Green Tea and Vitamin D for Bone Health

Green tea polyphenols combined with a form of vitamin D called alfacalcidol could boost bone structure and strength, according to a new study in mice.

The mixture may reverse damage to bones caused by lipopolysaccharide (LPS) induced chronic inflammation, which could in turn reduce the risk of osteoporosis.

Chronic inflammation causes bone loss through oxidative stress and excessive production of pro-inflammatory molecules.

According to NutraIngredients:

"The researchers reported that both extracted green tea polyphenols and alfacalcidol supplementations reversed LPS-induced changes in bone structure, whilst a combination of both was shown to sustain bone micro-architecture and strength."
