If its additional calories then makes sense it’s adding, especially if I’m right in thinking you’re not training super silly amounts at the moment. That said protein tends to promote fullness, so is often promoted as a way of eating less elsewhere.
I’m a big believer in suggestions that people doing heavy endurance exercise benefit from ~1.5g/kg, potentially up to 2g in very heavy training compared to average public needing 1-1.5g. Intake from various sources, and spread across multiple 20-40g sittings. Ideally around the 20g mark but can utilise higher amounts, and 8x20g isn’t always practical!
I get nearly all my 100-150g from food and little meat, but occasionally top up some porridge/yoghurt with an extra 10g. If work/training restricts time then a shake comes in handy once a week or so, but haven’t had one since June.
Otherwise I’m taking vitamin D for the first time this winter. With all supplements, and especially beyond those two you’re likely chasing inconsiquental effects compared to general diet, sleep, better training. Caveat being specific known deficiencies, eg B12 in vegans.
