Milk supply

So I originally planned on exclusively breast feeding. But ended up having to supplement with formula because he lost almost a pound when he was first born from not eating enough. Well needless to say, I’ve never had a really strong milk supply. Anything I can do to help increase my milk supply? I’ve been taking milk thistle capsules and they don’t really seem to help.
