Need help adjusting soluble fiber intake in overnight oats

Hi, 34y/o here, 172cm and 85-86kgs. On my last checkup my ldl is around 168.

I'm wondering if I can adjust the portions of my daily overnight oats to maximize soluble fiber content. Here is my current recipe per serving:

70g rolled oats 15g chia seeds 2g flaxseeds 2g psyllium husk

But generally, I would like to know what's a recommended portion of psyllium husk if I'm going to take it on a daily basis. I know that there's also varying amounts of fiber with oats, chia seeds, and flaxseeds, so I also consider them when thinking of fiber intake. That's why I also included my recipe in this post.

If it helps, I also eat 300g of veggies/fruits for lunch and for dinner in addition to 200g purple rice and 120g chicken breast. I dont always pick the veggies with the most soluble fiber, I just go with what I feel cooking/eating so the soluble fiber varies. With that said I dont think I can optimize soluble fiber on this area so I'm thinking of adjusting my recipe for overnight oats.

Any help would do. Thanks!
