The latest version of Randy Oliver’s Amino Acid Calculator was updated on May 6, 2025 (“V2025b”).
Key updates and features include:
- Continuous improvements and error corrections: Randy actively incorporates feedback and error reports from users worldwide. The recent update credits beekeeper Yannis Petrakis of Greece for support in testing and enhancing the calculator.[1][2][3]
- Balancing based on leucine: The calculator normalizes essential amino acid (EAA) ratios to leucine—the predominant EAA in bee diets—rather than to tryptophan, for more accurate nutritional comparison and easier matching to current recommendations.[1]
- Visual comparison: When you enter your diet’s amino acid profile, the calculator instantly displays how your EAA ratios compare to both de Groot’s classic recommendations (gray columns) and Oliver’s revised, research-driven targets (red columns). Your inputted values show up as green columns, making deficiencies and surpluses easy to spot.[1]
- Direct EAA concentrate addition: The tool now allows users to determine the exact amount of any EAA concentrate to add to bring their formulation into balance, making diet optimization more straightforward and cost-effective.[1]
- Global applicability: You can input any protein source or pollen substitute—from local to exotic ingredients. The calculator automatically identifies EAA deficiencies and calculates what you need to correct them, making it valuable for beekeepers with access to diverse proteins.[4]
In Summary
Randy updates the calculator’s recommendations and formulas regularly to reflect new research findings and field trials, so it’s crucial to always download the latest version for accuracy and best results.[2][3][1]
