Milk dust

Has anyone taken milk dust protein powder? I’m looking into it because it seems like my supply is going down 😭 I was easily pumping 6-8 oz per pumping session and now barely get 4 oz. it’s probably from not having time to eat enough (with all the nursing, playtime and keeping him entertained and trying to keep up with normal house stuff 😭). I have been exclusively breastfeeding and pumping once in the morning to build a stash and didn’t expect my milk supply to go down before I started to work again.
