Supplement

Supplements are items in the form of plants and pills in medication bottles that can be collected in The Last of Us and The Last of Us Part II single-player campaign by scavenging. They can be used by Joel, Ellie, or Abby for skill upgrades.
== Overview ==
 In single player, Joel can find supplements throughout most of the game. The pickups are small bottles or potted purple flowers. These are worth 5, while bigger bottles or potted flowers are worth 10. Supplements can be picked up whenever the  or icon appears on-screen. Additionally, shiv doors always contain at least 1 supplement in the bottle form. 
Supplements allow the player to upgrade any of Joel's 6 different skills: Maximum health, listen mode distance, crafting speed, healing speed, weapon sway and shiv master. Shiv Master upgrades are not available on Easy difficulty and cannot be purchased while playing on the setting. Upgrading Listen Mode Distance is disabled on Survivor and Grounded difficulty.
Supplements locations and quantities, like parts, do not vary between different difficulty settings. There are a total of 800 supplements that need to be collected in order to fully upgrade all of Joel's skills. While this cannot be done in a single play through, players can start a new game of the same difficulty with New Game Plus, and find the remaining supplements previously missed. Any supplements a player does not use will already be in Joel's inventory as soon as they pickup his backpack upon the start of a New Game Plus.
