when i first started looking at zinc, my serum level tested 8.6. back then i had no idea of zinc interrelationships with other processes. in time i would learn that i definitely had altered biochemical processes, as a result of no zinc to support the huge variety of processes that rely on zinc dependent enzymes for example. try measuring zinc levels. if yours are less than 18 you can expect to see signs of suboptimal zinc manifesting in widely variable ways from individual to individual.
fortunately it's a cheap experiment. my zinc costs about $12 for a bottle of 108 powder capsules. 11 cents per dose.
fortunately testing is also covered by provincial health coverage. the things that i have measured in conjunction with zinc - such as uric acid and d3 - were both typically low as seen in ms patients. both indicators improved considerably in terms of levels (ua and d3) and dose response (d3). bet if i had measured cortisol i would have seen a similar benefit. subjectively, given that cortisol is a stress hormone, i can definitely say that i used to feel stressed ALL THE TIME and nowadays i'm actually relaxed. so awesome
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
