Short answer: The main difference is the minimum measured methylglyoxal level: 100, 263 or 500 mg/kg. In the Puspamrta range, MGO 100+ is the gentle entry point, MGO 263+ an everyday step up, and MGO 500+ the popular stronger option.

The MGO concentration changes
MGO 100+, 263+ and 500+ respectively meet minimum methylglyoxal concentrations of 100, 263 and 500 mg/kg. The number is a product grade and remains the same across jar sizes.
Flavour and everyday use
MGO 100+ is an accessible first jar for mild daily enjoyment. MGO 263+ adds a more pronounced Manuka position without moving into the high-strength range. MGO 500+ is positioned for shoppers who prefer its richer flavour description. MGO concentration alone does not determine taste.
Each can be used in the same simple ways: from the spoon, over breakfast or in a warm drink. Choose the grade for taste and preference rather than assuming a larger number changes the required serving.
Comparing value
Compare the total for the exact jar size and pack quantity, not only the price displayed from the lowest-cost option. Multipack discounts differ by product and should be visible before checkout. Free Australia-wide delivery and GST-inclusive pricing make the final comparison clearer.
