Interactive evidence-based tools

Bone Health Calculator Hub

Use these tools to estimate intake, organize risk factors, and prepare better questions for a visit. They are educational and built from the PDF library, not loose internet summaries.

Educational only: these calculators do not diagnose osteoporosis, prescribe supplements, replace FRAX, or replace care from your own qualified healthcare professional.

Nutrition Calculators

These place your estimate next to context supported by the PDF library. Food, medical conditions, lab results, medications, kidney health, and clinician-directed plans can change what is appropriate.

Calcium Intake Calculator

Estimate calcium from food plus supplements, then compare with the total daily calcium range commonly discussed in osteoporosis reviews.

Enter estimates to compare with a calcium context range.

Reference: osteoporosis and nutrition reviews.1,2

Vitamin D Intake Context

Compare food and supplement vitamin D with PDF-supported context about deficiency risk, serum 25-hydroxyvitamin D, and dose safety.

Enter estimates to review vitamin D context.

Reference: vitamin D reviews and calcium/vitamin D fracture evidence.3,4

Protein Baseline Calculator

Estimate a baseline protein target using 0.8 grams per kilogram per day, then treat that as a starting point for discussion. This is not a muscle-building, fracture-recovery, sports, weight-loss, or kidney-disease prescription.

Enter weight to estimate a baseline protein target.

Reference: nutrition and sarcopenia reviews.2,5

Quick Reference Targets

TopicPDF-supported context used here
CalciumTotal daily calcium around 800-1,200 mg/day is commonly discussed in osteoporosis reviews when correcting deficiency.
Vitamin DVitamin D is often guided by serum 25-hydroxyvitamin D status; several osteoporosis sources discuss daily intakes around 800-1,000 IU in older or higher-risk adults.
Protein0.8 g/kg/day is a baseline adult reference point, while older-adult nutrition discussions often consider about 1.0-1.2 g/kg/day depending on context.

These are evidence-context ranges for discussion. They do not mean everyone should take a supplement to reach them.

Risk Discussion Prompts

Some bone-health topics should be handled as structured visit preparation, not as public online scoring. These tools create questions to bring to a clinician.

Osteoporosis Screening Prompt

Uses screening themes summarized in osteoporosis reviews as a starting point for a clinician conversation.

Enter age and select any factors you want to discuss.

Reference: osteoporosis screening reviews.8,9

Fall Risk Conversation Aid

Based on exercise, frailty, and fall-prevention evidence in the PDF library. This identifies fall-prevention topics to discuss, not a diagnosis.

Select any fall-related concerns.

Reference: exercise and falls-prevention reviews.6,7

Menopause Bone-Risk Prompt

Organize menopause-related bone questions, especially when estrogen loss may have started early or abruptly.

Add menopause details to create visit questions.

Reference: osteoporosis screening and management reviews.8,9

Male Osteoporosis Discussion Tool

Men can have osteoporosis, especially after fractures or with medication and hormone-related risks. Major reviews note that evidence for population screening in men is less certain, so this tool creates questions rather than a screening directive.

Select any topics that apply.

Reference: osteoporosis screening and management reviews.8,9

Calculators and Tools

FRAX

FRAX is a fracture-risk assessment model that integrates clinical risk factors and, when available, femoral neck bone density. BonegevityMD should not recreate it informally.

Open FRAX tool

Nutrition context

The nutrition page explains how calcium, vitamin D, protein, total energy, and medical context fit together in the PDF-supported evidence.

Open nutrition page

Falls and balance

The falls page turns exercise, frailty, and sarcopenia evidence into practical visit questions.
