So there are various habits and practices that can be implemented that will increase your bodies levels of BDNF.
More BDNF can cause neurogenisis (growth of new neurons) which can results in better learning and memory.
I’d imagine that doing these practices alongside subliminals can help your mind integrate the subliminals better.
Meditation, excercise, Wim-hof method, sunlight exposure, intermittent fasting, keto.
I personally do all of these except keto. I try and keep my sugar and carb intake lower though.
Oh and something else I forgot to mention.
Psychedelics even when microdosed will raise bdnf levels. I’d suggest if you take this route it’s better to microdose because even 5 ugs is enough to raise bdnf levels.
To put it another way. If you’re listening to quantum limitless but you’re over consuming sugar, staying inside all day, being inactive, etc then you aren’t stacking everything in your favor to improve your brain function.
