We tend to think of aging in terms of wrinkles, memory lapses, or slower metabolism. But what if one of the clearest predictors of longevity is hidden in your bones?
Bone loss doesn’t just lead to fractures. It accelerates decline in ways most people don’t realize. A broken hip, for example, can double your risk of death within a year. And yet, millions overlook calcium supplementation until it’s too late.
The question isn’t just whether you should take calcium; it’s which kind. The form you choose could support more than your skeleton. It might support your mitochondria, lower inflammation, and activate the same longevity pathways being studied in cutting-edge aging research.
In this article, we’ll explore the best calcium supplements for osteoporosis, compare the most common forms on the market, and introduce you to calcium alpha-ketoglutarate (Ca-AKG). This form of calcium, included in NOVOS Core, supports both strong bones and healthy aging.
Key Takeaways
- Calcium is essential for preserving bone density and reducing fracture risk as we age.
- Common forms of calcium include carbonate, citrate, and plant-based, but their bioavailability and side effects vary.
- Calcium alpha-ketoglutarate (Ca-AKG) provides elemental calcium and activates longevity mechanisms.
- NOVOS Core delivers 231 mg of Ca-AKG, along with synergistic nutrients for full-spectrum bone and aging support.
How Does Calcium Support Longevity & Bone Strength?
Bone health isn’t just about avoiding fractures. It’s about maintaining the freedom to move, live independently, and stay active as we age.
As Yale Medicine notes, bone mass plateaus after age 30. And after 50, we begin to lose bone mass faster than we can regenerate it. Women face a higher risk of osteoporosis because they naturally have lower bone density than men and experience further loss with the decline of estrogen during aging.
Strong bones can help mitigate these risks, reducing the likelihood of falls, hospitalizations, and immobility. They preserve muscle mass, balance, and neural coordination — foundational elements of healthy aging. Calcium plays a central role by supporting bone mineral density, but the type of calcium you choose matters.
Understanding the Different Forms of Calcium
Let’s look at the most common forms of calcium and how Ca-AKG is unique.
Calcium Carbonate
This is the most common and least expensive form of calcium. It’s widely available as an over-the-counter (OTC) supplement. Calcium carbonate provides a high percentage of elemental calcium but requires stomach acid for proper absorption. It’s best taken with meals and may cause gas or constipation for some people.
Calcium Citrate
Better absorbed than carbonate, calcium citrate is gentler on the digestive system but often delivers less calcium per dose. It may be ideal for older adults or those with low stomach acid.
Plant-Based Calcium (Algae-Based)
Sourced from marine algae, this form includes naturally occurring trace minerals. While appealing for its whole-food origins, absorption can vary, as can the quality of the product.
Calcium Alpha-Ketoglutarate (Ca-AKG)
Ca-AKG is a next-generation calcium form that combines elemental calcium with alpha-ketoglutarate, a molecule involved in the Krebs cycle and cellular metabolism. It not only delivers bone support but also activates pathways associated with longevity.
One of the best calcium supplements for osteoporosis is NOVOS Core. It includes 231 mg of Ca-AKG, alongside magnesium (a cofactor for calcium uptake) and vitamin C (essential for collagen synthesis in the bone matrix). Core also includes longevity-supportive ingredients like glycine, glucosamine sulfate, and hyaluronic acid — all of which contribute to connective tissue strength and joint resilience.
The Link Between Bone Health and Lifespan
Bone loss doesn’t just affect posture or comfort. It impacts survival.
Fractures reduce mobility, increase dependence, and raise the likelihood of hospitalizations and secondary health complications. Frailty and falls are among the strongest predictors of late-life decline. Maintaining bone strength, therefore, isn’t just about preventing breaks but also preserving quality of life and healthspan.
Unlike traditional calcium forms, Ca-AKG doesn’t stop at supporting bone density. It also helps reduce the inflammatory burden, preserve mitochondrial health, and protect against age-related muscle loss — all key factors in maintaining resilience in later life.
A Modern Approach to Bone Health
Calcium is essential, but calcium alone is not enough. For those seeking long-term skeletal support and healthy aging, Ca-AKG offers a unique two-for-one benefit: It provides bioavailable calcium while activating pathways known to extend lifespan in preclinical models.
NOVOS Core delivers 231 mg of Ca-AKG alongside magnesium, vitamin C, and other ingredients that support healthspan and lifespan. It’s a modern, multi-pathway approach to bone health and to aging well.

FAQ About Calcium Supplements & Osteoporosis
Which form of calcium is best for osteoporosis?
Calcium citrate and Ca-AKG are both well-absorbed and ideal for older adults. Ca-AKG also targets aging-related pathways that influence inflammation, stem cell function, and mitochondrial health.
Do calcium supplements help if you already have osteoporosis?
Yes. Calcium won’t rebuild lost bone, but it can slow further bone loss and reduce the risk of fractures, especially when combined with vitamin D, magnesium, and resistance-based exercise.
What is the silent killer of osteoporosis?
Osteoporosis often progresses without symptoms until a fracture occurs, commonly in the hip or spine. These breaks can severely impair mobility and are associated with increased mortality, making the disease a silent but serious threat to aging adults.
What is the best supplement for severe osteoporosis?
In addition to medications, an ideal supplement should combine high-bioavailability calcium with bone cofactors like magnesium and vitamin C. Ca-AKG adds longevity-supportive effects. It’s a strong choice for those managing severe bone loss while also supporting systemic aging.
What does the Mayo Clinic recommend for osteoporosis?
The Mayo Clinic recommends 1,200 mg of calcium daily for women over 50 and men over 70, ideally through a combination of food and supplements. They suggest calcium citrate for better absorption, especially in older adults, and emphasize the importance of vitamin D, strength training, and lifestyle changes to support bone health.
At NOVOS, we would add that Ca-AKG offers an exciting new approach. It provides bioavailable calcium while also supporting longevity pathways, such as mitochondrial health and inflammation reduction.
