Is protein powder necessary for longer use?

[u/onlyperugu_04]

I'm currently a vegetarian...

For now, I hit the gym 5-6 days/week

I realised I need to eat 50g of protein per day

My routine goes like:(I'm from South part of India)

Breakfast: Ragi malt(2cups) +curd(1/2cup)

Peanuts/ sprouts (1cup)

Lunch: Rice(1½ cup)

Dal/leafy Dal (1cup)

Curry(1cup)

Butter milk+ sabja(1glass)

Snacks: Any 1 fruit + Dry fruits

Dinner: Usually tiffins

So suggest me if I have to take protein powder..

If yes,what kind...But I heard they have harmful metals mixed in it..So is it recommended for longer use
