Micronutrients & recovery
High protein intake (>0.8 g/kg BW) does not negatively impact kidney function in healthy individuals, and may prevent bone loss when combined with adequate calcium and vitamin D.
If you have healthy kidneys, you do not need to limit protein for renal safety. For bone health, aim for higher protein intake (above 0.8 g/kg) but ensure you are getting enough calcium (>800 mg/day) and vitamin D, as protein helps calcium absorption and may reduce fracture risk in this context.
The evidence for associations between protein intake and kidney function and kidney stones in healthy people needs to be more conclusive... EFSA concluded that no maximum protein intake level could be established for those with healthy kidney function due to insufficient evidence.
Why this rating
Based on EFSA conclusions and specific RCTs; evidence is mixed for fractures but positive for bone mineral density in supplemented groups.

- Dietary protein quality is determined by essential amino acid content and digestibility (DIAAS), with plant proteins generally having lower bioavailability than animal proteins due to antinutrients.Good
- Replacing animal protein with plant protein in the diet is associated with lower cardiovascular disease mortality and all-cause mortality, particularly when substituting processed red meat.Moderate
