A quick puzzle for you: what do you get when you combine bone loss and muscle loss? If you guessed osteosarcopenia you’re way ahead of the game. 

As you can imagine, not many people know about this under-recognized and undertreated chronic musculoskeletal condition. 

So today we’re shedding light on the inner workings of osteosarcopenia and what you can do to keep it at bay. 

What is Osteosarcopenia?

Osteosarcopenia is a condition that describes the combined effects of osteoporosis (bone loss) and sarcopenia (muscle loss). 

As such, osteosarcopenia is a new term that represents a frail subset of the elderly population that is affected by this “hazardous duet” of both osteoporosis and sarcopenia.1 

This condition is especially common after age 65 due to a progressive decline in muscle mass (~1% per year) and bone mineral density (BMD) (~1–1.5% per year).2

Those who have Osteosarcopenia are at significantly higher risk of falls, fractures, and hospitalizations than others who only have osteoporosis or sarcopenia.

In fact, in a study of 316 elderly Chinese adults it was found that 10.4% of men and 15.1% of women were Osteosarcopenic. And the odds of frailty were significantly higher in osteosarcopenic patients compared to osteoporotic or sarcopenic patients alone.3

Symptoms of Osteosarcopenia

In many cases, osteosarcopenia is asymptomatic. But a previous history of falls and/or fractures in older people should alert physicians to the presence of osteosarcopenia. 

Since osteosarcopenia represents the combined effects of osteoporosis and sarcopenia, it can be helpful to pay attention to the risk factors of both these conditions.

Risk factors for osteoporosis and sarcopenia include:4

  • older age
  • female
  • high alcohol intake
  • oral glucocorticoids
  • menopause (females)
  • low protein intake
  • low bmi
  • current smoking
  • low dietary calcium
  • low serum vitamin D
  • hypogonadism (in men)
  • hyperparathyroidism
  • obesity
  • rheumatoid arthritis
  • living in residential aged-care facilities
  • chronic kidney disease
  • low mobility and function

Understanding the “Muscle-Bone Crosstalk”

So interesting fact of the day: bone and muscle like to chat it up. It’s true, their different molecular responses to each other are so varied and spontaneous that the process has been compared to a conversation and labeled “muscle-bone crosstalk.”

And grasping this interplay is key for understanding osteosarcopenia. It’s also essential for recognizing the interdependence of bone and muscle. 

Many researchers have found that bones, and muscles too, are actually endocrine organs in their own right. And their hormone and hormone-like products affect themselves, their local environment, and the entire body (autocrine, paracrine and endocrine functions).

In their studies, researchers have found more than 600 endocrine elements secreted by muscles. When it comes to bones, the number is far less. But some key molecules have already been identified and characterized.  

What has been learned so far indicates that bones, muscles, fat, and the collagen in joints are tightly connected. And changes to one of these elements will affect all the others. 

This introduces a totally new and more profound concept of physiology in which the entire body — all its trillions of cells — coordinate and complement each other like a beautiful, mighty symphony.

With that being said, this field is still in its infancy. Almost all the research brings up hints rather than conclusions. 

So we’ll stick to a few well-documented effects of a few substances — the ones that give us some guidance in our diets and lives. But first, we’ll need a little help from Wolff’s law. 

Wolff’s law is a nineteenth century formulation of how activity builds bone. It states:

 “The architectonic of a bone follows the lines of force to which that bone is exposed.”

Two current theories describe the mechanics of Wolff’s law. 

How Wolff’s Law Works: Two Theories

One theory cites integrins. These are multiple small projections from bone cells that work their way into the fibers of bone, as in the figure on the right. Once they are in the bone they stimulate structures deep within the osteocytes.

These structures can include the cell nucleus or the mitochondria — the power-stations of the osteocytes.5And these changes set the cell up to work so it makes new bone.6

The other theory ascribes mechanotransduction to the cell membrane. This fancy sounding process involves changing mechanical stimuli (bending, compressing, or twisting the cell) into another form of energy — electricity.

So just think of an electron volt on the inside of a cell powering a chemical reaction to produce a new protein. This new protein will find its way into the cell nucleus and upregulate certain DNA. It will then promote the changes that make for new bone.7-12 

In either case, pressure on the bone deforms it slightly. This stimulates bone cells to make new bone right where the bone sustains the force. 

Now that we’ve covered Wolff’s law, let’s look at three of the better understood components of muscle-bone crosstalk, for hidden in this crosstalk are the underpinnings of Wolff’s law.
But first, apologies are given in advance that much of this information comes from animal studies. Yes, the field is that new. But it’s old enough that multiple studies confirm that mouse DNA acts very much like human DNA.12 As in the case with humans, every substance they secrete has built-in checks and balances.

What is Osteocalcin?

Osteocalcin (OCN) comes from osteoblasts (bone building cells) in three forms: carboxylated, undercarboxylated, and non-carboxylated. For our purposes, the under- and non-carboxylated forms are the most important.  

These forms enhance muscle contraction causing the muscles’ fibers to grow and multiply rapidly. 

As a result, muscular decline reverses — even in 15-month old mice (probably the equivalent of a 51 year-old person).7-12 

What’s more, the undercarboxylated OCN prods pancreatic beta cells to release insulin, which goes back and helps the bones’ metabolism. 

Further, the carboxylated OCN prompts the hypothalamus to promote sympathetic (fight-or-flight) responses.  

While all this is going on, insulin prompts the body’s fat cells to release leptin. This is the check and balance action that makes the brainstem secrete serotonin, putting reins on the hypothalamus’s sympathetic tone.

Often billed as rivals, osteocytes and osteoclasts (the cells resorbing the matrix of bone) work together in this. 

Once considered the enemy of bone strengthening, bone resorption raises active OCN levels. And osteoclasts that decarboxylate OCN make it active — another check and balance.

According to Wolff’s law, this is nature’s shrewd way of limiting and coordinating the entire process of remodeling bone. 

How to Increase Osteocalcin in the Body

So we know that OCN is good for us. But how do we increase the number of molecules of OCN coursing through our systems?

Well for one, you can take Vitamin K, especially K2. It has a direct effect on osteocytes and stimulates OCN production. 

Another way to boost OCN levels is to lose weight. Shedding extra pounds frees the hormone and hormone-like substances in muscles, bones, and fat cells that stimulate OCN.

As you know, a great way to lose weight is to exercise. In addition to helping you stay in shape, exercising also helps improve bone density and muscle strength. 
So consider adding a twelve-pose yoga sequence to your exercise routine that has been shown to build bone. It’ll give your bones and OCN levels the boost they need.13

What is Myostatin?

A second part of the muscle-bone crosstalk involves myostatin. 

Myostatin is a member of the transforming growth factor beta (TGF-β) superfamily which inhibits skeletal muscle growth — it also has effects on bone and tendon.14

Specifically, myostatin keeps the muscles under lock and key, reducing their mass.  Androgen (a male hormone) decreases myostatin. 

In addition, exercise lowers myostatin, prompting the muscles to grow in volume and strength.

This also makes for the enlargement and strengthening of the parts of bone that muscles attach to. In this way myostatin helps shape and remodel bone.

What is Sclerostin?

Finally, a third part of the muscle-bone crosstalk involves sclerostin. Sclerostin is a small protein expressed by the SOST gene. It reduces osteoblastic bone formation.15 

As such, it’s an important regulator of bone remodeling. It also assists in the crosstalk that shapes the large hip bone and wrist.

Mitigating the Risks of Osteosarcopenia

As in the case with osteoporosis and sarcopenia, there are lifestyle changes you can make to help keep osteosarcopenia in check.


As mentioned earlier, regular exercise is key to having healthy bones and muscles. It has many positive effects on the older population, with one meta-analysis finding exercise reduced overall fracture risk by 51% in adults over 45 years old. 16

Moreover, exercise programs are even effective for frailer adults, with a meta-analysis of elderly residents in long-term care demonstrating a 29% reduced risk of falls in those that underwent combined resistance and balance training programs.17


A lack of adequate intake of vitamin D and protein has been linked to declining muscle strength.18 Vitamin D deficiency also leads to increased risk of falls through its multiple effects on muscle and bone (Kaji, 2014).19

So vitamin D supplementation can have many beneficial effects, including increased muscle strength, decreased mortality and falls, and functional improvement. Guidelines generally advocate 800-2000 IU/day.20

Adequate calcium intake is also advised in patients with osteosarcopenia (To learn more about calcium intake visit here)

According to Dr. Robert Heaney, internationally recognized expert in the field of bone biology and calcium nutrition, “Protein is necessary if calcium is to help us build or rebuild bone. Recall that bone is about 20% calcium by weight but 50% protein by volume.”

The current recommended daily allowance (RDA) for protein intake is 0.8 grams per kg of body weight.23 But this RDA was set over a decade ago, and experts now believe it’s not an adequate amount.

More recent research recommends that older adults consume 1–1.5 grams of protein per kg of body weight.

    I got the results from my bone density test this morning. My results were SIGNIFICANTLY better in some areas and stable in the others! I have been taking AlgaeCal since my last scan and for the last several months , I have walked 3 miles a day and exercised with weights. I’m thrilled that my doctor said he will continue to monitor me, but will not push an injected drug every 6 months as he was previously. Thank you!!!

    How much Vitamin D should we be taking in one day?
    What are the side effects if you are taking too much Vit. D?
    And is there Vitamin D, Vit K1 or 2, in Algaecal which I am taking?
    And what else is added to Algaecal ?

    Hi Denise! Gosh, thank you for bringing to our attention that we missed answering Beverly’s questions!

    Vitamin D is a tricky nutrient, and as everyone’s individual needs vary, it’s best to check in with your doctor to test your blood levels. Research shows the optimal range is between 50-80 ng/ml, and the 1600IU’s in AlgaeCal Plus is enough for most people to keep their levels quite steady. If your blood levels of vitamin D go over 80, then blood calcium levels may increase beyond the normal, healthy range.

    AlgaeCal Plus contains vitamin K2 (MK7) which is the form that will helps most with calcium absorption! To learn more about this, click HERE! 🙂

    AlgaeCal Plus contains the ocean algae Lithothamnion superpositum, which provides the highly absorbable calcium, some magnesium and trace minerals. Extra magnesium, vitamin K2, D3, boron and vitamin C are also added to enhance your ability to absorb calcium, and support the bones! For more information on our ingredients, click HERE!

    Very interesting research update. While protein is important for calcium uptake is there any difference in the recommended amounts if it is animal protein vs. plant protein? Animal protein is a stimulant for IGF-1 and not recommended by plant-based dietitians.

  19. Kendra AlgaeCal

    September 26, 2022 , 1:42 pm

    Hi Gail,

    This is a wonderful question! In our understanding, vegetarian protein sources fall short of the protein content animal sources offer so you need to eat more calories with plant proteins! You might find THIS article on our website helpful 🙂 I would also recommend reaching out to your healthcare provider for further support!

    I highly recommend Dr. Fishman’s yoga poses. I’ve been practicing yoga for over 30 years and added his regimen about 1 year ago. . His regimen is easy to adhere to and only about 20 minutes. I add more poses if I have the time.
    I am not a morning person, but have to get up at 5 AM to be at work by seven. I am almost always able to squeeze in my 15 to 20 minutes doing Dr. Fishman’s routine and then get some walking and stairs while I’m at work. Off workdays I add weights and longer walks and some more strenuous yoga like kundalini. I feel great since I’ve been doing this. I’m not sure the numbers but my femur readings on my DEXA scan last year showed improvement and my doctor thought it was artifact in the reading 🤷‍♀️, but I think it was the yoga and weights! Looking forward to starting AlgaeCal- hoping I don’t have to go to higher level medication’s with my osteoporosis .

    I am 76 year old female. I have had two knee replacements and have osteo in my heberdins nodes. In 2011,I was able to reverse osteopenia w K2 w Mk7. somewhere I stopped taking it. in 2019 I remembered K2 and took it again to reverse Osteopenia on the other hip. maintained K2 and Vit D 10,000 daily but k2 was different and weaker. last month I had lower bone density and left hip is,weak and left leg is thinner than the right by over 1 and 1/2 inches. I’ve been taking rock cal/mag. Question, is there enough K2 in AlgaeCal to reverse Osteo again or should,I keep my new Stronger K2 w 45,000 mcg’s along with AlgaeCal? $ issue….

    Hi Linda,

    We’re so sorry to hear of everything you are experiencing! Most people taking AlgaeCal Plus do not need to worry about additional vitamin K2 supplementation. However, if you are taking additional D3, then your requirements for Vitamin K2 also increase. If you are still taking more that 5000IU total of vitamin D3 (AlgaeCal Plus provides 1600IU), then an addition 100mcg of K2 would be suitable.

    I hope this helps Linda, please reach out to us at 1-800-820-0184 if you ave any additional questions! 🙂

    Hi Mary,

    I’m so sorry to hear of what you are experiencing. The good news is that in 2016, AlgaeCal published a 7 year long study which involved participants to take AlgaeCal and Strontium Boost for 7 years. Not only did our participants see increases in their bone density each year of this study, but there were zero negative side effects reported. We have also been issues GRAS status from the FDA, which stands for Generally Recognized as Safe!

    We certainly would not expect for AlgaeCal to negatively affect your condition, however we do recognize everyone is unique with individual sensitivities. For your peace of mind, we also offer a Risk Free Return Policy. We also have many customers in our community that also unfortunately suffer from autoimmune conditions, that take AlgaeCal without issue! 🙂

    I hope this helps Mary! Please reach out to us at 1-800-820-0184 for any questions!

    Hi Melanie,

    I’m so sorry to hear of everything you are going through. Diet and exercise will play a big, helpful role in supporting your bones, however this is unfortunately often not enough to combat normal, age related bone loss. AlgaeCal can help! AlgaeCal is the only calcium supplement that is clinically supported by 3 studies to increase bone mineral density. We have thousands of customers on our program that are seeing wonderful results, and you can see some of their stories HERE 🙂

    In our human clinical studies, AlgaeCal Plus alone increased bone density by an average of 1.3% in a year. However, when it was taken together with Strontium Boost, it almost tripled the rate of bone density increases! So this means an average increase of 3% in a year! Click HERE to read more about our clinical research.

    I hope this helps, Melanie! If you have any questions, please reach out to us at 1-800-820-0184 (USA & Canada toll free), and any one of our Bone Health Consultants would be happy to help!

    About 1 1/2 years ago I discovered a studio in my neighborhood that is for “55 and older”. Classes usually from 5-8 folks and 30 min long. Our coaches are trained to know how to deal w/achey bones and joints and also balance problems. I love it; I
    go 3 times a week. At 85 it has been a wonderful find for me!
