Soy and peas isolate proteins.

I was searching for low cost protein powder and came across these two types that are the cheapest.
What do you think? I remember someone wrote about some bad things concerning high usage of soy - does it have the same risk taking isolate proteins?
What about peas'?
peas proteins have:

25g of proteins per 30g

0,9 g of fats

 

soy:

27g of proteins per 30g

0,9 g of fats

 

the soy ones are the cheapest of all.

 

Do you guys have any advice?

I would buy a small amount of each, try then, and compare how you feel. People tend to have different preferences for protein types.

 

Personally, I prefer pea protein - as soy makes me feel a little stuffed and bloated. But others would say the opposite.

Surely whey protein would be the cheapest?

I found this brand is the cheapest in the country I live in, but whey cost more than those two types.

the difference isnt enormous (3-4 euros), but I have to spend the least possible and in the long term I would be able to buy one more package with the same difference

Use the one with the most amount of calories per serving.

 

The body uses calories for energy to make repairs not grams of protein. Plus you will get some amount of protein from any food that has a cellular wall.

I'd vote for Pea between the two personally. Soy tends to make my nose runny and I sneeze, a mild alergic reaction I guess. But that's me personally. Had this thing called Vegan protein blend with peas, brown rice and hemp protein. Didn't have any reaction to it, however it didn't mix very well.
