Are milking bombs really increase mums' breasmilk?

Milking bombs, or known as lactation cookies where the main ingredient is made from Oats. Oats is very nutritious and known to increase milk supply. For me, I took 2-3 lactation cookies daily and didn't see much improvement on the milk supply. How did I get more supply was mainly from latching my baby more often and drink more hot soup/beverages. I think if depend solely on lactation cookies it will not help in increasing milk supply. It's a combination of frequency of pumping/latching, well rested, enough sleep, eat healthy and balanced diets.
