Definitely not. Eat balanced and you won't need supplements. Cheaper too.
I can't actually agree with this! Protein Supplements offer an EXTREMELY cheap source of protein for the body. Lets compare some average quality chicken from tesco, to a protein supplement from Myprotein:
Chicken -
Price: £5.00
Protein Per "Serving" (100g): 23.5g
Portion Size To Receive 20g Protein: 85.1g
Price Per 20g Protein: 55p
Average Protein Powder -
Price: £15.79 for 1kg (Chocolate Smooth Flavored)
Protein Per "Serving" (25g): 19g (lowest possible taking into account flavoring)
Portion Size To Receive 20g Protein: 26.4g
Price Per 20g Protein:41.8p
As you can see from the data above that I have calculated, it is actually a lot cheaper to purchase a supplement like the one above, than chicken as an example. Please do bear in mind, supplements can actually be purchased even cheaper than this too. This was a small size container and if bought in larger quantities, would lower the price even more per 20g protein.
