Crucial nutrients for strong bones & health

Life Extension Europe, woman and man running on the beach in summer

Medical research has discovered conclusive links between bone health and system-wide health.

Osteoporosis is one of the consequences of inadequate bone nutrition, but strong bones do much more than prevent life-altering fractures. Check the impact on strong bones and find the crucial nutrition.


The impact of bone health on overall health

Latest news in bone research

Scientists at the leading edge of osteology (bone research) are discovering that in addition to preventing fractures, a healthy skeletal system is also essential to (1-4):

  • Immune strength
  • Blood cell production
  • Nervous system function
  • Insulin sensitivity
  • Energy metabolism
  • Cardiovascular health 
  • Weight management

Find out how a comprehensive nutrient regimen, including calcium, trace minerals, and vitamins D3 and K optimizes bone health and total health.


The bone nutrition you need

Adequate bone nutrition hinges on the following group of nutrients that work synergistically to optimize bone health and fend off multiple diseases of aging: Calcium, vitamin D3, magnesium, vitamin K, potassium, boron, zinc, manganese, silicon, and lactoferrin.

Calcium

Calcium accounts for 1-2% of adult human body weight, with more than 99% of total body calcium residing in the teeth and bones. 

The remaining 1% is used in our electrically active tissues such as nerve and muscle, where it plays a vital signaling role. 

Thus the skeleton is the body’s only storehouse of the calcium we need to sustain life itself, yet as we age we see a progressive decrease in the amount of calcium in our bones. 

Consuming a readily-absorbed form of calcium, then, is essential for restocking that reservoir, but many people do not ingest adequate amounts of calcium. (5)

Vitamin D3

In order to absorb calcium from the diet or from supplements, the human body requires vitamin D

For years, we believed that promoting calcium absorption from the intestinal tract was the chief function of vitamin D. But over the past decade there has been an explosion of scientific discoveries about vitamin D’s multiple roles throughout the body. (6,7) 

We now recognize that vitamin D functions as a hormone, with receptors located in at least 35 different tissue types. That means the body’s overall requirement for vitamin D is much greater than we originally realized. (6-9)

With regard to bone health, vitamin D not only promotes calcium absorption but also its proper deposition in bone tissue, where it helps maintain the skeleton’s basic function as scaffold and protector of soft tissues. (10) 

Elsewhere in the body, vitamin D acts at its specific receptors to promote immune function, subdue inflammation, reduce arterial calcification, enhance cardiac function, improve brain and nerve tissue performance, and even prevent cancer by regulating the cell replication cycle.  (7,11, 12)

Conversely, vitamin D deficiency is associated with not only bone diseases, but also cardiovascular disease, the metabolic syndrome, cancer, immune suppression, and autoimmune conditions such as multiple sclerosis, lupus, and inflammatory bowel disease. (10, 12-15)

The combination of our increased knowledge about the importance of vitamin D throughout the body, and the widespread lack of adequate levels, has resulted in a rapidly growing international call for increased vitamin D intake. (6,16-18)

Many experts in the field recommend supplementing with doses of 2,000-10,000 IU per day in order to achieve optimal total-body vitamin D status for optimal skeletal, cardiovascular, neurological, immunological, and metabolic health. (16,19-21)

Magnesium 

While calcium and vitamin D have been considered the mainstays of bone nutrition and osteoporosis prevention, several other minerals are also essential to good bone health. (22,23) 

Magnesium is an element that is involved in more than 300 essential metabolic reactions. Magnesium is also vital to human nerve and muscle cell function. Fully one-half to two-thirds of the total body content of magnesium is stored in bone — another example of the skeleton’s substantial role as reservoir for important minerals. (24,25) 

While blood levels of magnesium remain virtually constant throughout life, the total body content diminishes with aging, leading to depletion of the skeletal stores. 

Magnesium deficiency is therefore common among older adults, who typically consume inadequate amounts of magnesium-rich foods and whose physiology may contribute to increased losses of the element from the body. (26)

Deficiency of magnesium is a risk factor for osteoporosis and is also associated with a long list of other chronic ailments, many of which are themselves age-related. These include virtually all forms of cardiovascular disease, insulin resistance and diabetes, lipid disturbances, increased inflammation and oxidative stress, asthma, chronic fatigue, and depression. (26)

Plentiful consumption of magnesium is an important part of good bone nutrition. Higher dietary intakes are associated with higher bone mineral density. (24, 25, 27,28) 

While the mechanisms of this effect are not entirely clear, it is known that magnesium supports a more alkaline environment in bone and other tissues, which helps to reduce calcium losses in the urine. (22, 27) 

Magnesium also reduces markers of excessive bone turnover, helping bones retain their vital mineral mass. (29) Increasing magnesium intake improves bone mineral density and bone strength in both animal and human studies. (28,30) 

Conversely, magnesium deficiency may impair the beneficial effects of calcium supplements. In magnesium-deficient rats, calcium supplements suppressed bone formation, a worrisome finding. (31)

That study serves as an important reminder of the importance of comprehensive bone nutrition that includes more than simply calcium and vitamin D. (22) 

Simultaneously increasing calcium and magnesium intake helps promote a favourable change in cytokines that can promote bone formation. (32)

Vitamin K 

Attention to the importance of vitamin K2 in supporting bone health has grown over the past decade. It works alongside vitamin D3 to keep calcium in bones where it belongs and out of arterial walls where it does not. (33,34) 

Vitamin K2 reduces production of bone-absorbing cells (osteoclasts) and promotes development of bone-forming cells (osteoblasts). (35,36) 

Vitamin K2 is required for production of a small family of proteins that include the bone matrix proteins and the essential bone-produced hormone called osteocalcin. (8,37)

Healthy bone matrix proteins hold tightly to calcium and maintain bone’s integrity and strength, reducing your risk of osteoporosis. 

And ample supplies of osteocalcin directly improve insulin sensitivity, reduce fat accumulation, and are associated with lower levels of leptin, a fat-produced hormone that’s implicated in the metabolic syndrome. (38,39)

Vitamin K2 increases osteocalcin production and improves bone mineral density, and may protect against fracture risk. (40-44)

Potassium

Potassium is one of the predominant ions in the human body, and it is essential to maintaining health at the cellular level. An ion is a mineral or element that has a positive or negative charge. Even apparently minor potassium disturbances can produce significant cardiovascular disorders. 

Older adults are at substantially increased risk for having low potassium levels, in part because of lower dietary consumption of potassium-rich fruits and vegetables and also because of the side effects of many common medications such as certain diuretics like furosemide, thiazides such as hydrochlorothiazide, asthma medications such as albuterol inhalers, and the cancer chemotherapy drug cisplatin. (45,46)

Potassium helps maintain a more alkaline or non-acidic tissue environment, which benefits bone health by reducing calcium losses in urine. People with higher potassium intake boast higher bone mineral density, reducing their risk of osteoporosis and potentially life-changing fractures. (27,47)

Animal studies show that increasing potassium intake in combination with exercise improves both bone density and bone mineral content. (48) A modest amount of potassium, therefore, is a wise addition to a bone-health regimen.

Boron 

Boron is a trace mineral that is essential to healthy bones since it supports the functions of calcium, magnesium, and vitamin D. (49-52) In a revealing study, postmenopausal women consumed a boron-deficient diet for 17 weeks, followed by 7 weeks of boron consumption. 

While on the boron-deficient diet, the women showed increased urinary loss of calcium and magnesium. When boron was re-introduced to their diet, urinary loss of calcium and magnesium declined, and hormones linked with healthy bone mass increased. These findings suggest that boron is crucial in helping maintain the body’s optimal stores of bone-building calcium and magnesium. (51)

Modern eating habits make it difficult to obtain adequate amounts of boron from the typical diet. Scientists have discovered a plant-based form of boron called calcium fructoborate. 

Naturally found in fruits, vegetables, and other foods, this form of boron is highly stable and bioavailable and may provide antioxidant capabilities in addition to bone-building benefits. (53,54)

Zinc, manganese & silicon

The minerals zincmanganese and silicon play important roles in optimal bone formation and health. Low levels of each of these minerals may contribute to bone loss, and increased intake improves bone health in animal and/or human studies. (55)

Why vitamin D & K is a powerful combination

Osteoporosis (decreased bone mass and bone mineral density) is a serious and growing healthcare problem in Europe.

And osteoporosis is only one of the consequences of inadequate bone nutrition.

The most recent research reveals that weak bones contribute to increased fat mass, decreased insulin sensitivity, inflammation, and greater risk of cardiovascular disease.

Morover, people with osteoporosis are more likely to exhibit atherosclerosis (thickening or hardening of the arteries) in their blood vessels. 

And those with atherosclerosis are more likely to possess lower bone mass. What do these groups have in common? Both conditions involve insufficiencies of D and K. (56-59)

While most people now know they need to maintain optimal levels of vitamin D, conventional medicine has failed to alert them to the equally vital need for vitamin K. Both of these synergistic nutrients are required to combat atherosclerosis and osteoporosis, two prevalent and life-threatening degenerative diseases.

Cutting-edge research points to the central role of two key nutrients to ensure optimal calcification of your bones while preventing pathologic calcification of your arteries: vitamins D and K.

It's becoming increasingly clear that we need both vitamins D and K to get our dietary calcium into bones, where it belongs, and to keep it out of arteries, where it doesn’t

Vitamins D and K can work individually and together to keep our arteries young and supple — and to prevent the myriad disorders associated with arterial stiffening.


The power of lactoferrin

All the nutrients above provide the raw material for healthy bones. 

However, the process of rebuilding weak bones caused by osteoporosis and building new ones is a complex operation that requires something more. As we age, old, unhealthy (senescent) cells accumulate within our bones and bodies. 

These cells have lost the ability to replicate and refuse to die off to make way for new, healthy cells. Moreover, they secrete harmful signaling molecules that actively weaken bones and accelerate bodily aging. These signaling molecules increase the activity of cells that absorb bone and decrease the activity of bone-forming cells. The result is that the bones become weaker, more porous, and prone to fracture. 

Research shows that the protein called lactoferrin gives bones the instructions they need to both reduce bone loss and increase the building of new bone. In one study, a lactoferrin product increased markers of bone-forming activity by 24% more than a placebo! (60)

Moreover, lactoferrin is known for its strong immune-boosting properties, and studies suggest that it can promote cellular regeneration helping the body heal and repair itself. 

A typical dose of lactoferrin is 300 mg once or twice daily. Taken orally, lactoferrin is readily absorbed.
