Is it true that eating a high-protein diet has a negative impact on bone health?

For a while, a study was often referenced that showed a correlation between people who ate a high protein diet (more than 0.8 grams for 1 kg of body weight) and a loss of calcium.  This contributed to a widely dissipated myth that consuming high levels of Protein is somehow harmful to your Bone’s density.  This study was misinterpreted in making the correlation that a loss of Calcium was the result of eating too much Protein, and wrongly suggested a decrease in bone density.

Research shows that getting enough protein helps:

✅ Boost bone density – Reducing the risk of fractures
✅ Enhance calcium absorption – Strengthening your skeletal structure
✅ Support aging bones – Keeping them resilient as you get older

Here’s what the science says:

📖 Higher protein intake improves bone mineral density – Osteoporosis International

🥛 Protein enhances calcium absorption – American Journal of Clinical Nutrition

🦴 Strong bones at any age – The Journal of Nutrition

Make sure your diet supports your bones for a healthier, stronger future!

💡 Tip: Combine protein-rich foods like lean meats, dairy, and legumes with other bone-building nutrients like calcium and vitamin D for maximum benefits.

The quality of a protein source depends on its amino acid profile. John’s Killer Protein is formulated to be the best source of protein, containing all the essential amino acids in the ideal ratios.
