I would not go with oil capsules if you want to increase ALA intake. You never know if the oil is still fresh, or if it was produced with an oxidised batch already.
If you eat oatmeal, grind up a tablespoon of flax seed and add it. Always grind fresh, or keep a small batch in your fridge for a week. The oils oxidize pretty quickly once the seed is broken. This will give a good baseline of ALA and flax is generally good for your digestion.
Other than that, I would get some DHA+EPA in a 2:1 ratio (or even more EPA) and supplement that as recommended.
Viel Spaß damit! 🥰
