Omega-3 fatty acids have been found to support healthy bone mineral density by promoting bone mineralization [3]. Bone mineralization is the process through which minerals, primarily calcium, are incorporated into the bone matrix, strengthening the bones.
According to studies, a higher overall omega-3 (DHA) intake is associated with healthy bone mineral density [4]. Omega-3s help in this process by promoting a healthy inflammatory response, which is crucial for optimal bone health.
In a 2016 study published in the Journal of the American College of Nutrition, researchers examined the effects of omega-3 supplementation on markers of inflammation and bone health in postmenopausal women [5].
They divided 117 healthy postmenopausal women into two groups. One group received milk fortified with the omega-3 fats DHA and EPA. The other group received milk fortified only with vitamins A and D, without omega-3 enrichment.
After following their respective milk regimens for 12 months, the women who had received the DHA and EPA-enriched milk saw healthier levels of C-reactive protein (an inflammatory marker) and RANKL (an inflammatory protein that activates osteoclasts responsible for breaking down bone tissue).
Another important aspect of omega-3s role in bone health is their ability to support bone-building cell activity. These fatty acids have been shown to stimulate the activity of osteoblasts, the cells responsible for building new bone tissue [6].
At the same time, omega-3s can support the healthy function of osteoclasts, the cells responsible for breaking down bone tissue [7].
This balance between bone formation and resorption is essential for maintaining strong and healthy bones.
