Calcium is essential to building and maintaining strong bones. Blood levels of Calcium are carefully managed so that bone cells receive enough Calcium to perform their structural function without pulling calcium away from bones into other parts of the body for other uses.

Milk, yogurt and cheese are excellent sources of calcium for those who can tolerate dairy products; those who cannot or are allergic may get enough from other foods like dark-green leafy vegetables, canned fish with bones included, tofu and calcium-fortified drinks and cereals.

Diet

Achieing strong bones starts with getting enough of the essential nutrients – calcium, vitamin D and other vitamins/minerals/fatty acids that support bone health – such as calcium. Eating foods from all four food groups and participating in physical activities will ensure you stay strong throughout your life.

Dairy products are well-known sources of calcium, but other foods also provide essential bone-building nutrients. A cup of spinach offers one-fourth of your daily calcium requirements while plant milks – like almond, rice and soy varieties – have calcium added fortification that meets levels found in dairy.

Fatty fish like salmon, tuna and mackerel provide calcium and vitamin D as well as protein, potassium and omega-3 fatty acids that may support bone health.

Leafy greens such as bok choy, Chinese cabbage, kale and collard greens are packed with calcium-rich foods like bok choy, Chinese cabbage, turnip greens, broccoli and turnip greens are an excellent source of vital bone-supportive vitamins such as vitamin K and folate; in just one cup of cooked turnip greens alone you could find 20% of your daily calcium requirements! Other vegetable sources of calcium include apricots and oranges while one cup of black beans provides another 84%.

Vitamin D

Calcium is best known for supporting healthy bones and teeth, but it also plays an integral part in blood clotting, muscle contraction, heart rhythm regulation and nerve transmission. Over 99% of our calcium stores can be found in bones and teeth but smaller amounts may also exist in blood, extracellular fluid or skeletal muscles.

Vitamin D is essential to bone health, helping the body absorb and utilize calcium. Without adequate amounts, children may develop rickets while adults can suffer osteomalacia due to sun exposure or by eating certain food like fish, meat and dairy products which produce Vitamin D naturally. Low levels of blood calcium concentration increase fracture risk significantly.

Vitamin D’s beneficial effects on fractures may be the result of its immunoregulatory and anti-inflammatory properties, along with its ability to calcinate NO molecules involved in cortical bone formation. Additionally, vitamin D could have an impactful calcination process effect that helps produce mineralized cortical bone.

Studies show that an individual’s risk of fracture can be decreased by increasing calcium consumption through diet and supplements. While daily requirements depend on age and gender, experts recommend individuals consume enough calcium to reach 20-30 ng/mL serum levels.

Magnesium

Magnesium is an indispensable mineral, closely linked to calcium and other key bone-building nutrients. Magnesium plays an integral role in hundreds of metabolic reactions involving protein production, muscle and nerve function regulation, blood sugar regulation, calcium absorption and energy production (Rondanelli 2020).

Studies have demonstrated the correlation between magnesium intake and bone density for men and women regardless of age or menopausal status, regardless of either party being premenopausal. It plays an integral part in the calcification process by controlling its transport across cell membranes into cells where calcium serves vital roles for nerve conduction, muscle contraction and heart rhythm regulation. Excess calcium deposits itself in soft tissues causing kidney stones, arterial calcification or lung calcification as well as even heart disease; but with an appropriate diet combining magnesium with calcium can prevent these issues by returning its calcium back where it belongs – in bones.

Diet is often the best way to attain adequate amounts of magnesium; however, some individuals may struggle to meet their magnesium needs through this alone and may require supplements as an additional means.

Magnesium not only aids calcification processes but also activates the hormone calcitonin, which draws calcium out of soft tissues and the blood and into bone, helping prevent arthritis and kidney stones. Calcitonin also activates osteoblasts – cells responsible for building new bone – so as to limit any bone loss due to menopause or aging.

Magnesium also appears to offer protection from the bone-degrading effects of prescription osteoporosis drugs such as Fosamax and Alendronic acid by blocking an enzyme called NFATc1 that regulates parathyroid hormone; this leads to more balanced calcium-phosphorus ratios and less risk of fractures.

Zinc

Zinc is an essential mineral for bone health and is involved in protein formation, hormone production, bone mineralization and metabolism regulation. A deficiency can result in weak bones more susceptible to fractures and osteoporosis; supplementation has been found to increase bone density among children while helping older adults avoid osteoporosis.

Studies on the cellular and molecular mechanisms through which zinc promotes bone growth, homeostasis, and regeneration suggest it may increase both endochondral and direct bone formation. Furthermore, experiments that directly compare its effects on chondrocytes and osteoblasts suggest it promotes their proliferation while suppressing osteoclast activity – something it impairs by way of inhibiting osteoclast proliferation.

Researchers have studied how adding zinc ions (with their smaller ionic radius than calcium ions) into various calcium phosphates like hydroxyapatite, b-TCP, brushite or monetite can enhance their biological performance as bone substitute materials. Zinc can be introduced by partially substituting or inserting them between two oxygen atoms within an OH group column in these materials.

These modifications may affect the biological properties of materials by increasing their permeability and increasing their capacity to foster bone formation. Studies have demonstrated this by showing how mesoporous HA and ZnHA produced approximately one third more bone than just HA alone in a rat metaphyseal defect model; ceramic cylinders with mixed ZnHA/TCP substitution proved more osteogenic in a rabbit femoral metaphysis defect model.

Omega-3 Fatty Acids

Omega-3 polyunsaturated fats have long been touted for their cardiovascular benefits and reduced risks of atherosclerosis, but studies have also demonstrated their positive influence on bone health. Omega-3 fatty acids appear to decrease fracture risks and bone loss by suppressing inflammation in the body.

Omega-3 fatty acids are essential fatty acids that your body cannot produce itself and must obtain through food or supplements. Examples include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Your body uses fatty acids to manage inflammation in its various systems, including your bones. Inflammation causes decreased bone density and an increased risk of osteoporosis; studies have demonstrated how omega-3 fatty acids found in fish oil help to decrease inflammation, which allows osteoblasts (bone-building cells) to function optimally.

Studies have demonstrated that diets high in EPA and DHA can significantly benefit bone health by decreasing inflammation, slowing bone resorption, and stimulating new bone formation.(3)

Fatty acids play an integral part in mesenchymal stem cell differentiation, serving as precursors of bone-building osteoblasts and fat-forming adipocytes respectively. Omega-6 fatty acids like linoleic acid (LA) may direct MSCs toward fat formation while omega-3s such as alpha-linolenic acid (ALA) steer them toward producing osteoblasts(4)

Researchers studied 1,865 postmenopausal women measured their bone mineral density with dual-energy X-ray absorptimetry and kept food records; then they compared this group with one that received supplements containing ALA, EPA and DHA from either fish oil or plant sources such as flaxseed oil or walnuts containing omega-3 fatty acids ALA/EPA/DHA with that consumed the highest quantities, having significantly greater increases in BMD and reduced risk of fractures than all the others groups combined. The results of their comparison showed participants with higher omega-3 intake had significantly greater increases in bone mineral density as well as decreased fracture risk than their counterparts.
