Cissus Extract Calzbone®
Bone Support That Helps Your Body Use Calcium More Effectively
Overview: What This Ingredient Does
CalzBone® is a branded extract of Cissus quadrangularis, a plant traditionally used to support bone strength and structural resilience.
One of the most common misunderstandings about bone health is that it’s only about how much calcium you take. In reality, bones are living tissue — they’re constantly being broken down and rebuilt. CalzBone® is designed to support this bone remodeling process, helping create an environment where minerals like calcium can be incorporated into bone tissue more effectively.
In Bone Densi-T, CalzBone® works alongside calcium, vitamin D, magnesium, and vitamin K2 to support stronger, more resilient bones over time.
Where It Comes From & How It’s Made
CalzBone® is derived from the stem of the Cissus quadrangularis plant, which grows in tropical regions of Africa and Asia. The stem has long been used in traditional wellness systems for structural and connective tissue support.
What differentiates CalzBone® from generic Cissus powders is that it’s produced as a standardized botanical extract, meaning specific bioactive plant compounds are preserved at consistent levels from batch to batch. This standardization is important for both research consistency and real-world results.

How It Works in the Body
Bones stay strong through a balance of two ongoing processes:
- Bone formation (building new bone)
- Bone resorption (breaking down old bone)
CalzBone® supports this balance by providing plant-based compounds that help support:
- Normal bone remodeling signals
- Healthy mineralization of bone tissue
- Structural support within bone and connective tissue
Rather than acting as a mineral itself, CalzBone® helps support the biological environment that allows foundational nutrients — like calcium and vitamin D — to do their jobs more effectively.
What Clinical Studies Show
Human Research on Cissus quadrangularis
Clinical research has evaluated Cissus quadrangularis extracts — the botanical standardized as CalzBone® — for their role in supporting bone health–related biomarkers in humans.
- A systematic review of randomized controlled trials involving Cissus quadrangularis supplementation found that human studies showed support for normal biochemical markers involved in bone metabolism, including markers related to bone turnover and hormonal regulation. This suggests a supportive role in maintaining healthy bone balance over time. Source (peer-reviewed review of human trials): https://doaj.org/article/67bf539f56474493a3dad43ace52a5ef
Branded CalzBone® Research
- Supplier-hosted clinical research summaries on CalzBone® specifically describe outcomes related to bone mineral density (BMD) and bone marker changes in adult women with low bone density when CalzBone® was used as part of a supplementation program. These materials tie the research directly to the CalzBone® extract, not just the plant in general. Supplier research overview: https://vs-corp.com/resources/research_brands/calzbone/
Traditional Use Supported by Modern Context
- Cissus quadrangularis has a long history of traditional use for supporting bone integrity and structural repair, reflected in ethnobotanical literature. Modern clinical research builds on this history by examining how the plant’s bioactive compounds influence bone-related biological signals.

Together, these sources support CalzBone®’s role as a botanical complement to mineral-based bone nutrition, rather than a replacement for calcium or vitamin D.
Why This Research Matters
- Includes human clinical research, not just traditional use
- Supported by a systematic review of randomized trials
- Uses a standardized botanical extract, which improves consistency
- Explains why bone health requires more than minerals alone
- Aligns with long-term bone support, not short-term fixes
What This Ingredient Is Best Known For
- Supporting healthy bone remodeling
- Helping maintain bone mineral balance
- Complementing calcium and vitamin D in bone formulas
- Supporting overall skeletal resilience
- Providing plant-based structural support for bones and connective tissue
Safety & Considerations
CalzBone® (Cissus quadrangularis extract) is generally well tolerated at the amounts used in dietary supplements.
As with any supplement:
- Those who are pregnant, nursing, or managing medical conditions should consult a healthcare professional.
- Bone support works best as a long-term, consistent approach, combined with adequate nutrition and weight-bearing activity.
