First Aid kits are a lifesaver in Subnautica 2 because you can not only die due to lack of food, water or air but also get hunted by underwater creatures. And the best way to restore health during fights or environmental damage is through first aid kits. This guide shows the exact crafting recipes, where to harvest Medical Gel and Fiber, so you can stop gambling with just food heals and carry reliable medical supplies on every expedition.
Crafting Requirements


Crafting first aid requires you to have a fully functional fabricator as the fabricator in Lifepod has limitations. And to get a fully functional fabricator, you first need to build a base and then build a fabricator inside the base.
Crafting Basic First Aid Kit


Crafting the Basic First Aid kit only requires 1 material, Fiber. You can craft fiber using the fibrous pulp you get by harvesting the plants like Whip Gorgon, then use the fiber to craft the basic first aid kit. Using a basic first aid kit restores 50 health.
Crafting Enhanced First Aid Kit


Enhanced First Aid kits require 1 additional material along with fiber, Medical Gel Sac. You can get a medical gel sac by harvesting the stem of the Acidic Raion Pouch, which is at the center and green in color as shown in the above image. This first aid kit restores 100 health upon usage.
