Substantial studies documented a preventive role of omega-3 fatty acids in pathological calcification like vascular calcification and microcalcification in cancer tissues.

In parallel, these fatty acids improve bone quality probably by preventing bone decay and augmenting bone mineralization. This study also addresses that the functions of ω-3FAs not only depend on tissue types, but also work through different molecular mechanisms for preventing pathological calcification in various tissues and improving bone health.

This study infers that supplementation of omega-3 fatty acids aids in bone preservation in elder females at the risk of osteoporosis and also, on the contrary, omega-3 fatty acids interfere with pathological calcification of vascular cells and cancer cells.

The Relationship Between Sleep, Breast Cancer and Osteoporosis What is interesting is that osteoporosis, sleep problems and some cancers seem to be related. What the Research Shows Our Omega Restore vials contain three primary ingredients that may have benefits related to osteoporosis: melatonin, omega-3 fatty acids, and vitamin D3.

Melatonin While best known for its role in regulating the circadian rhythm, melatonin is indispensable for a multitude of cellular functions, including bone and tooth formation. Omega-3 Scientists also believe that getting enough omega-3 fatty acids could have a positive impact on bone health.

Vitamin D3 Of the three nutrient types, vitamin D is the best known for its role in promoting and maintaining healthy bones. Influences on the Gut Flora In their recommendation of vitamin D, however, scientists may have ignored an important point: Raw cod liver oil is a nutrient-rich liquid containing not just vitamin D, but a multitude of substances, including omega-3 fatty acids and other vitamins.

Liquid Supplements Versus Pills The lack of ingredient synergy could perhaps explain why clinical trials show that vitamin D3 supplementation alone has a limited or inconsistent effect on osteoporosis.

In line with this, omega-3 supplementation should be included with chemotherapy for cancer patients as it can prevent osteoblastic potential of breast cancer patients, responsible for pathological mineralization, and blocks off target toxicities.

Administration of omega-3 fatty acid with chemotherapy will not only improve survival of cancer patients, but also improve the bone quality. Thus, this study allows a better understanding on omega-3 fatty acids in combating pathological complications such as osteoporosis, vascular calcification, and breast microcalcification.

Omega-3 fatty acids are among the most studied nutrients and have been associated with numerous health benefits, reports Dr Bente J. Foss, Chief Technology Officer at GC Rieber VivoMega. EPA and DHA are only found in seafood and, especially, in oily fish.

As the formation of EPA and DHA is limited in humans, we must rely primarily on dietary sources to get sufficient levels of omega-3s.

Physiological functions in humans Highly unsaturated long-chain fatty acids such as EPA and DHA have two critical physiological functions in humans. First, as an integral part of the phospholipids in cell membranes, they contribute to an optimal membrane structure that allows intercellular communication and vital functions.

Second, as primary precursors of bioactive lipid mediators, including the eicosanoids, they are indirectly involved in cell signalling processes inside the cell and between other cells.

Through these physiological functions, omega-3 fatty acids exert anti-inflammatory and immune-modulating actions that may positively impact our health. The connection between omega-3s and bone and joint health Our bodies consist of bones and the joints form the connections between those bones.

Any damage to the bones and joints from disease or injury can cause pain and, even worse, negatively impact our mobility. Bones and joints are maintained by complex physiological mechanisms in which nutrients such as EPA and DHA serve a role.

Research has shown that by impacting bone metabolism, EPA, DHA and other lipid biomolecules derived from them may reduce the risk of bone fracture and decrease bone loss. Omega-3s for bone and joint conditions Osteoarthritis OA is a degenerative joint condition in which the cartilage within a joint begins to break down and the underlying bone begins to change.

The main symptoms of OA are pain and stiffness in the joints. A study from looked at the association between plasma levels of fatty acids and synovial inflammation in patients who had or were at risk of knee OA.

In this study, it was found that patients with high levels of plasma omega-3s, specifically DHA, had lower cartilage loss in the knee joint compared with a placebo. A recent meta-analysis covering nine randomised clinical trials and patients with OA showed that daily EPA and DHA supplementation significantly relieved arthritis pain when compared with a placebo and was also associated with improved joint function in these individuals.

Interestingly, the observed improvement in arthritis pain was better in patients younger than 65 than in those older than Rheumatoid arthritis RA is a chronic inflammatory disorder that first affects your joints but can also affect other body systems.

Epidemiological studies have shown that dietary intakes that are low in omega-3s increase the risk of developing rheumatoid arthritis; further, it has been reported that diets including weekly fish consumption have resulted in significantly lower pain in patients with RA than ordinary diets.

Supporting these findings, several clinical trials have shown that omega-3 fatty acid supplementation may reduce the number of tender joints, early morning stiffness and pain levels in RA patients.

Owing to a condition known as osteoporosis, our bones weaken as we age. Clinical studies indicate that supplementation with EPA and DHA may help to improve bone strength and, consequently, fractures by increasing calcium absorption, bone calcium content and bone mass in humans.

The beneficial mechanisms behind omega-3s Bone metabolism is a lifelong cycle of growth and resorption, and also controls the formation of bones after fractures or damage from normal activity. Our bones get more fragile as we age because of increased activation of the inflammatory signalling pathways, which negatively impact bone metabolism.

Studies have indicated that EPA and DHA regulate bone metabolism by reducing the release of lipid mediator prostaglandin E32 which is involved in regulating both bone formation and resorption , interacting with osteoclast receptors cells that cause bone resorption , modulating inflammatory cytokines, increasing calcium levels in the bones and by reducing oxidative stress, which is also linked to bone resorption.

Many experimental studies have shown that EPA and DHA can modulate inflammation by reducing the levels of inflammatory components, such as certain cytokines. Ensuring proper omega-3 intake EPA and DHA are only found in seafood and, in particular, fatty fish such as mackerel and herring.

EPA and DHA are formed in the human body by the conversion of alpha-linolenic acid ALA: n-3 , but the extent of this conversion is small. Thus, the inherent methodological limitation of evaluating the supplementation of fatty acids is unavoidable Due to this, it is not surprising that the previous studies are controversial while still puzzling.

Most of the observational studies found that BMD was positively correlated with the supplementation of omega-3 PUFA or fish oil. Similarly, in a study of 76, women and 45, men enrolled, the fracture risk was negatively correlated with the consumption of omega-6 FAs and PUFAs In contrast, a few researchers reported no statistically significant relationship between consumption of PUFAs and BMD or the incidence of fracture 44 , Other studies observed completely different findings in which a higher intake of PUFAs may deteriorate bone loss In a recent meta-analysis that enrolled 28 RCTs 7, participants , the experimenter reported that the increased supplementation of omega-3 FAs may exert a low magnitude to the increase in BMD of the lumbar spine by 2.

Another interesting finding that emerged from the analysis is that the increasing intake of total PUFAs may have little to no effect on BMD Recently, in a single-center study of postmenopausal Spanish women, a high level of plasma omega-3 FAs was an independent risk factor of bone health The vast discrepancy of various studies may be attributed to multiple complex confounders such as sex and gender, etc.

One notable confounder is that the consumption of cod liver oil rich in vitamins A and D was likely to exert influence to some degree on bone health 48 , Some researchers attempt to explain this phenomenon with more objective and more profound mechanisms, such as circulating fatty acids.

Based on the Framingham Osteoporosis Study, which included participants, a negative trend was observed between arachidonic acid AA and risk of hip fracture Another cross-sectional study indicated that greater red blood cell omega-3 FAs were beneficial to decrease the risk of hip fracture One important finding is that the influence of fatty acids on BMD may vary dynamically over time, beyond possible sex differences In accumulating animal experiments, the mechanism of PUFAs affecting bone health could be better elaborated.

Deep down to the microlevel, the benefits of fish oil is closely linked to the presence of allelic variants in some genes such as PPAR γ, according to a comparative study on mice with polymorphisms in the PPAR γ gene 6T On the contrary, no effect of consumption of PUFAs on bone structure or metabolism was found in healthy mice.

The dietary ratio of significantly elevated the amount of DHA in the bone tissues of the femur. This conclusion was also supported by some observational population study; in an investigated population with a higher intake ratio of omega-3 FAs to omega-6 FAs, such as the Japanese population, a lower ratio of osteoporosis was reported In addition, different dietary sources of omega-3 FAs exhibited significant disparities in biochemistry and metabolism.

Rozner et al. found that flaxseed oil was effective in ameliorating the micro-architecture, and fish oil could improve BMD, in which the core mechanism may be the alteration of peripheral clock in bone cells Some study limitations should be noted, although the rationale of MR analyses made it superior to conventional observational studies in excluding the existence of confounders.

First, we only focused on the causal associations between a specific type of PUFA and BMD and did not take into consideration some other nutrients that might interact with PUFAs and cause bias.

The potential limitation might contribute to the implausible casual relationship between PUFAs and BMD to some extent.

Therefore, we conducted MR-Egger and MR-PRESSO methods to exclude the potential pleiotropy. Furthermore, the PhenoScanner tool was adopted to screen and remove the SNPs associated with confounders. Hence, the conclusion of this study should be creditable.

Second, the samples were not further substratified according to gender and age, which were believed to be important risk factors of BMD based on previous studies. However, the effect on our analyses could be small due to the strength of the large sample size.

Lastly, the exact mechanism underlying the causality between them was not explored in-depth. Therefore, a mechanistic research should be carried out in the future.

This two-sample MR analysis produced strong and new genomic evidence that there was causal relationship between omega-6 FAs and BMD. However, a further validation by MVMR and bidirectional MR suggested that the association between them may be caused by the interactions of metabolites and reverse causality.

doi: Nutrition Omega 3 Osteoporosis and Exercise By Margaret Martin Last updated on October 8, at am. Table of Contents. Omega 3 Osteoporosis Study.

Study Groups The research involved four groups of women between the ages of 58 and The four study groups were: Exercise plus Omega 3 group Exercise only group Omega 3 supplement only group No intervention — the control group.

Methodology One thousand mg of Omega 3 polyunsaturated fatty acids PUFA was added to the daily food intake for 24 weeks for the two groups that took Omega 3 supplementation.

Results The authors report the following findings: Prior evidence indicates that both dietary fats and physical activity can influence bone health and alter inflammation.

The novel findings are: Twenty-four weeks of aerobic exercise in combination with omega-3 polyunsaturated fatty acids supplementation synergistically increases L2-L4 and femoral neck BMD in healthy post-menopausal women.

Augmentation of estrogen, osteocalcin and 1,25 Vit D levels were seen after 24 week with exercise plus supplementation only. Conclusions by the Researchers The researchers wrote the following conclusion: Aerobic exercise training plus omega-3 polyunsaturated fatty acids supplementation was effective in reducing chronic inflammation and increasing BMD in postmenopausal women.

A study 1 found that men who had the highest levels of polyunsaturated fatty acids PUFAs , omega-3s, and EPA had the lowest risk of general fracture compared to men with the lowest levels of PUFAs, omega-3s, and EPA.

The women in this study experienced a lower risk of general fracture when they had higher levels of PUFAs. Another study examining postmenopausal women found a similar trend when looking at hip fracture.

In fact, the study asserts that the amount of α-linolenic acid ALA , eicosapentaenoic acid EPA , and total omega-3 polyunsaturated acids PUFAs in red blood cells is a major predictor of hip fracture.

Higher levels of omega-3 fats were associated with a lower risk for fracture. Many studies cite high levels of PUFAs as protective against bone. This includes both omega-6 PUFAs and omega-3 PUFAs.

However, research has found that there is significance in the ratio of omega-6 PUFAs to omega-3 PUFAs. It makes sense that a high omega-6 to omega-3 ratio would increase the risk of hip fracture. It is well known that having too many omega-6s compared to omega-3s contributes to a variety of serious inflammatory diseases such as heart disease, cancer, and autoimmune disorders.

Not only does data support that omega-3s dramatically reduce fracture risk, but also the research suggests that omega-3s directly impact bone mineral density.

This is done by facilitating bone mineralization, reducing inflammation, and protecting against excessive bone breakdown. Bone mineral loss is the result of an imbalance between bone formation by osteoblast cells and bone resorption by osteoclast cells.

Omega-3s can increase bone-building cell activity and reduce the activity of bone breakdown cells. One study even suggested that 4. Not only have the bone benefits of omega-3s been replicated in populations all over the world, including in South Korea 6 , China 7 , Spain 8 , and Iceland 1 , but they have also been seen in studies conducted by NASA on astronauts who have lived beyond our world.

Astronauts lose bone because of the weightlessness they experience in space travel. On average, astronauts lose 1 to 1. To combat this bone loss, researchers investigated the effects of omega-3s and found that astronauts who consumed more fish and therefore more omega-3s suffered less bone loss following their return from 4- to 6-month space flights.

Glucocorticoids such as prednisone, are the main cause of secondary osteoporosis and osteoporosis before the age of Reducing the damage to the bone from steroid medications is very important and a recent Russian study suggests that omega-3 fats can help.

Although this was an animal study, it demonstrated that omega-3 fats can prevent bone loss from steroid use. This is most likely due to the anti-inflammatory actions of omega-3 fats.

We look forward to more human studies, as well as newer and more innovative studies in the future to confirm these findings. Here at the Center for Better Bones, omega-3 fats rank amongst the important bone-building nutrients, as does the ratio of omega-6s to omega-3s.

Now, with breakthrough technology, it is possible with a simple at-home blood spot test to get a comprehensive analysis to measure both your omega-3 fats and your omega-6 to omega-3 ratio, and to detect if you have toxic trans fats.

More prospective clinical studies and basic research are needed to back up these results. We have studied a sizable amount of literature. However, to our knowledge, the saturation effect and threshold between MUFAs and BMD are not supported by any pertinent data. The exact mechanism is yet unknown, and more studies are needed to confirm it.

There is no literature on the saturation effect between SFAs, PUFAs, and BMD. Therefore, in the future, we suggest carrying out a larger prospective study on SFAs, PUFAs, and BMD to further understand the causal relationship between fatty acids and BMD.

Since there are only total SFAs, PUFAs, and MUFAs intakes in the NHANES database, but no specific fatty acid intakes, such as the specific intakes of n-3 and n-6 PUFAs, we suggest that future studies should focus on the association between specific fatty acids and BMD.

In conclusion, SFAs, MUFAs, and PUFAs intake were positively associated with BMD, and the associations persisted in subgroups stratified by age, gender, and race in this study. Notably, when fatty acid intake was quartiled, MUFAs in the 2nd quartile were negatively correlated with BMD and those in the 4th quartile were positively correlated.

Meanwhile, this research found that MUFAs were positively correlated with BMD, but there was a threshold.
