Health Boost

In Minecraft, "Health Boost" is an unused status effect intended to increase the maximum health of a player or mob. Each level of Health Boost adds 4 maximum health points (equivalent to 2 hearts). Unlike the "Absorption" effect, the extra health provided by Health Boost starts empty and needs to be filled through natural regeneration, regeneration effects, or instant health effects. This effect is primarily obtained through commands or custom potions. The icon for Health Boost is represented by three increasingly larger hearts. In Java Edition, when the Health Boost effect ends, the extra health is lost, and may cause a brief jolt in the player's view. In Minecraft Earth, there were “Boosts”, enhancements to player abilities, obtainable by purchasing or scanning mini-figures that provided various in-game benefits, including health boosts. However, Minecraft Earth was discontinued in 2021. Additionally, in the game, entities such as wolves and iron golems visually show their remaining health, while others, like horses and donkeys, regenerate health naturally over time.
