MORNING STACK:
My morning routine is as follows when it comes to nutrition and hydation for a busy day:
24 oz water (preferably filtered or alkaline etc)
10 grams of Glutamine
5 grams of Creatine

Coffee (currently using Matt Brown's Immortal Coffee. pretty good dark roast.)
1/2 tbsp of Inositol
1 Scoop of Collagen powder

(Not Pictured)
A source of salt
1 LMNT pack
pickle juice
Re-Lyte
or home made Bone broth.

Reasoning for all:
Glutamine: Immune Health, Protein and muscle Synthesis, Digestive health, and Brain health.
Creatine Monohydrate: Athletic performance, Cognition, Brain function, Makes me thirstier so it encourages me to stay hydrated throughout the day, makes me feel strong AF
Coffee: Because its the only thing that keeps me going on this god forsaken planet some mornings, also Caffeine has numerous athletic performance enhancing qualities
Collagen: Good for your joints, nails, skin, etc. I personally notice reduced joint pain when consistently taking collagen.
Inositol: Popularized by Dr. James Dinicolantoio, Inositol has showen to be a great sweetener, that improves brain health, sleep, cognition, mood etc. I try to get 3-6 grams total per day.

Salt sources: For athletic performance and to prevent cramping and fatigue during high output training. I sweat a ton and am a salty sweater so i need lots of dietary salt to keep up.
