Newly published research has revealed one more tool for reversing osteoporosis. And the good news is that you can easily incorporate this new approach to improving bone quality and density into your current bone-healthy habits.
It has to do with controlling the accumulation of senescent cells, which are cells that have stopped dividing due to damage or aging. In today’s article, you’ll learn about the negative impact of senescent cells on your bones and two natural compounds that science has confirmed can effectively eliminate them, helping to prevent and reverse bone loss.
Senescence, Cells, And Bone
Senescence is a cellular mechanism activated in stressed or damaged cells to end cellular growth and reproduction. When cells enter senescence, they release chemical compounds that signal the immune system to destroy them. 1
However, as we get older, our bodies become less adept at removing senescent cells, resulting in the accumulation of the chemical compounds they release. These compounds cause inflammation, tissue dysfunction and deterioration.2
Therefore , senescent cells play a direct role in aging and age-related conditions that are caused or exacerbated by low-grade chronic inflammation including atherosclerosis, cancer, Alzheimer's disease, type 2 diabetes, and osteoarthritis.3
Until recently the role of senescent cells in osteoporosis was unclear. But research conducted at the Mayo Clinic has concluded that the chemical compounds released by accumulating senescent cells are a driving factor of bone loss.4
When cells enter senescence, they release inflammatory compounds to mark themselves for removal from the body. When aging slows the removal process, the accumulation of inflammatory compounds contributes to age-related conditions, including osteoporosis.
The Eradication Of Senescent Cells And Osteoporosis
The Mayo Clinic study used multiple methods to target senescent cells in naturally aged mice with demonstrated bone loss. The mice’s age was the equivalent of older than 70 human-years. The study targeted senescent cells in three ways:
- A genetic intervention that eradicated senescent cells
- An enzyme-inhibiting drug that prevented the senescent cells from releasing their proinflammatory compounds
- A senolytic drug that eliminated senescent cells
All three methods resulted in enhanced bone mass and strength. The treatments didn’t have the same effect on younger mice, indicating that the senescent cells are linked explicitly to age-related bone loss. The beneficial effects of the experimental treatments were due to lower bone resorption paired with either maintained or increased bone formation.
Here is the conclusion of the study:
“Collectively, these data establish a causal role for senescent cells in bone loss with aging, and demonstrate that targeting these cells has both anti-resorptive and anabolic effects on bone. Given that eliminating senescent cells and/or inhibiting their proinflammatory secretome also improves cardiovascular function, enhances insulin sensitivity, and reduces frailty, targeting this fundamental mechanism to prevent age-related bone loss suggests a novel treatment strategy not only for osteoporosis, but also for multiple age-related comorbidities.”4
If the “novel treatment strategy” involves the senolytic drugs used in the study, then this strategy will prove unsafe and undesirable. The mice were given a combination of dasatinib (Sprycel), which is a drug used to treat certain forms of leukemia, with quercetin, a plant polyphenol.
The authors emphasized that this drug only needs to be administered intermittently to achieve the desired effect, which they claim would reduce the risk of side effects when compared to daily use. Once a day is the typical dosing schedule for dasatinib.
Sprycel (dasatinib), taken once daily for chronic myeloid leukemia has an array of severe side effects including:5
- Anemia (low blood cell count)
- Severe bleeding that can lead to death
- Fluid retention in the lining of your lungs, stomach cavity, and the sac around your heart
- Abnormal heart rate and other heart problems
- Heart attack that can lead to death
- Pulmonary Arterial Hypertension (PAH)
- Severe skin reactions including sore mouth, sore throat, blistering and peeling
- Shortness of breath
- Muscle pain
Even if the risk of these side effects is lower on a different dosing scheduling, they aren’t risks worth taking, especially when there are safer alternatives. We know that senescent cells contribute to bone loss, but you don’t need to take life-threatening cancer drugs to target them.
The study found that targeting senescent cells improved bone mass and strength. Mice were given Sprycel (dasatinib), a drug used to treat myeloid leukemia known to have many dangerous side effects, combined with the polyphenol quercetin.
Fisetin: An Effective And Safe Senolytic Antioxidant
Savers may already be familiar with the polyphenol antioxidant fisetin.
Fisetin fights inflammation via multiple metabolic pathways.6 That already makes fisetin a powerful all-natural tool for reducing fracture risk. Here are some of fisetin’s beneficial functions:
- Inhibits the formation of collagen-destroying Advanced Glycation End products (AGEs)7
- Maintains levels of the Master Antioxidant glutathione6
- Increases resveratrol levels by slowing its breakdown8
- Protects brain function and prevents cognitive decline9
- Protects mitochondria6
- Prevents DNA damage, guarding against cancer10
We can now add to the list that fisetin eliminates senescent cells, reversing a variety of age-related conditions, including osteoporosis. A study released in October of this year found that fisetin is a potent senolytic. This passage from the study describes the results:
Of the 10 flavonoids tested, fisetin was the most potent senolytic. Acute or intermittent treatment of progeroid and old mice with fisetin reduced senescence markers in multiple tissues, consistent with a hit-and-run senolytic mechanism. Fisetin reduced senescence in a subset of cells in murine and human adipose tissue, demonstrating cell-type specificity. Administration of fisetin to wild-type mice late in life restored tissue homeostasis, reduced age-related pathology, and extended median and maximum lifespan.2
This finding confirms fisetin as an essential component to naturally reverse osteoporosis. And fortunately for Savers, fisetin is present in many fruits and vegetables that are likely already a part of your pH-balanced diet.
Sources of fisetin include:
- Cucumbers* with skin
* Foundation Foods
Make sure you include these foods in your diet to get the bone-building senolytic effects of fisetin.
The polyphenol antioxidant fisetin has been found to be a potent senolytic, making it a safe and natural way to eliminate senescent cells thereby improving bone quality and density.
Tocotrienols: Potent And Natural Senolytic Compounds
Tocotrienols are a group of chemicals that belong to the Vitamin E (tocopherol) family. Vitamin E has been shown to help build strong muscles and protect cells against damage from free-radicals. This, in turn, helps to build strong bones.
Like fisetin, tocotrienols are antioxidants. Some of their overall health benefits include11:
- Neuroprotective properties
- Anticancer properties
- Lowering cholesterol
- Fighting inflammation
Tocotrienols have also been found to prevent cellular aging by modulating cell proliferation signaling pathways. A study published in 2015 found that tocotrienols slow the cellular changes associated with aging, and promote cell division and specialization.12 Slower aging prevents cells from reaching the phase of senescence, in which cells release the chemical compounds that cause inflammation.12
Tocotrienols are naturally occurring compounds that may already be a part of your diet. Top sources of tocotrienols include:
- Palm oil
- Rice bran oil
- Wheat germ
- Coconut oil
- Grape seed
- Pumpkin seed
The bioavailability of tocotrienols is limited, but studies have found that they become detectable in appreciable levels in the plasma after supplementation.11 Therefore, to make the most of the senolytic function of tocotrienols, it is best to take a supplement in addition to consuming the foods mentioned above. At the Save Institute, we recommend taking a daily dose of 500 to 800 mg of a tocotrienol complex supplement consisting of alpha, beta, gamma, and delta tocotrienols.

I find it so disappointing, after reading about a particular product (in this case, TrueE) and all its advantages, that it is not available outside the USA. Perhaps an agency could be found in Australia, where I live, and thus reduce the enormous cost of postage. Could you please look into this Vivian? Thank you.
Interesting information about these senescent cells. Thank you.
If l ordered this supplements, how soon l should know if this supplements is helping with my Osteoporosis.
Good morning Vivian,
I appreciates your hard work for sharing, helping us informed, and
keeping us update on what is important for us. Thank you.
Have a wonderful day,
Palm oil is very saturated oil, how can it be so good for the liver?
Just wondering why there is a * besides so.w foods and some without
I have just completed an order for 6 bottles of True E, but it has been declined as no deliveries are made to NSW Australia where I live. I assume therefore that the offer is only available for US residents. Thank you for the good information though.
vivian i heard that you should not take vitiam e if you use to smoke it will cause lung cancer is this true
