Nutrition from Cronometer
This nutrition tracker goes beyond calories and macros to break down the total micronutrient profile of common foods and add it all up, making it easier to achieve total micronutrient sufficiency.
By connecting this, we could track single variables as magnesium, vitamin d, c etc. as well as our macros over time, and correlate them with mood, training results, sleep etc.
