The safest general approach is to thaw slowly rather than quickly. Moving frozen food from the freezer to a fridge the night before it's needed gives it time to thaw evenly without sitting at room temperature for hours, which is where bacterial growth becomes more of a concern. Where a fridge isn't practical, a sealed bag placed in room-temperature water, changed periodically as it cools, is a commonly used alternative that still avoids the extremes of very hot water or direct heat sources, both of which can affect the food unevenly and pose a burn risk if used carelessly.

For anyone reassessing how much livefood to order, [working through the available pack sizes and delivery frequencies](https://reptilecentre.com) is a practical way to line up order quantity with actual consumption, rather than sticking with a quantity chosen before the collection's needs were fully clear.
None of this is medical guidance, and dusting shouldn't be treated as a way of managing or correcting a health issue in an animal. If a reptile is showing signs of illness, poor condition, or unusual behaviour, the right step is to speak to a reptile-experienced vet, not to adjust supplement dusting at home.
This is a general good-practice principle rather than a precise science with fixed timings or quantities that apply to every household. How long to gut-load, and how often, depends on the insects being kept, the conditions they're kept in, and the feeding schedule of the animals they'll go to. Rather than following a single fixed rule, it helps to build gut-loading into the same routine as storing and checking livefood day to day, so it becomes a habit rather than an extra step.
Gut-loading is one of those livefood practices that sounds technical but is actually a simple idea: feeder insects are fed nutritious food for a period before they're offered to a reptile, so that whatever is inside the insect's gut at the point of feeding passes on some of that nutritional value too.
