Alpha-linolenic acid (ALA) is an omega-3 fat from plants. Flaxseeds, chia seeds, and walnuts supply it. The body turns a small fraction of ALA into the longer omega-3s EPA and DHA; the rest is burned for energy or stored.
People take ALA to help maintain normal skin moisture and support cardiovascular function. Others use it as part of a daily routine for joint comfort or immune health.
Take ALA with food to improve uptake. Liquid oils and softgel capsules are common forms. Steady daily use matters more than a large single dose.
Caution: ALA can slow blood clotting. Get a doctor’s guidance if you take blood thinners. Large amounts may upset the stomach.
