For stress...

Tried ashvagandha, hemp, chamomile, rosemary and lavendar? [And any spices high in caryophyllene.]

Add a maximum dose of 1200mg CBD (known as "the schizophrenic reset dose") can do similar wonders as large doses of ashvagandha, of microdoses of psilocybe mushrooms. Or any less extreme dose.

Large frequent doses of magnesium bisglycinate can help too. As can other things, like amino acids like creatine & carnatine, fat soluble vitamins of adequate diversity & quantity, fish oil, sunlight, red light therapy, sound therapy (isochronic, binaural, solfeggio, rife, reiki music, etc, all that stuff), probiotics like lacto' reuteri, meditation and visualisation techniques, emotional freedom technique, and so on.

And of course eliminating/reducing any stimulants and any highly rajasic (or dosha imbalancing) foods (or situations). Even EMF shielding for sleep.

And Tummo Breathing (made famous by the Wim Hof Method), atop all that stress-countering stuff, can go even further, increasing resilience. (And it's free feel-good drugs already in your body). Only do where safe to momentarily trip or pass out (not while driving, swimming, standing, etc.).

Or at least, works fairly well for me.
