No-rona yet, unvaccinated and can count the number of colds I've had in like the past 5 years on one hand.
When I do get a virus, I tend to clear it in 1-2 days.
Possibly my vitamin regime helps:
4000iu Vitamin D + 100aug Vitamin K2 mix, 4-5 times a week.
1200mg Vitamin C + 40mg Zinc mix, 1-2 times a week and an extra if I've been in very close contact to someone who's been sick.
Diet wise, outside of the general norm I consume a lot of:
-Woodland / Asian mushrooms like shiitake oyster etc...
-Oily fish like mackerel, salmon, tuna, seam bream, sea bass, anchovies
-A fuck different ton of spices and herbs in my dishes, curries, rice dishes, soups, salads etc...
-Broccoli and cauliflower
-Dark chocolate, like 70%
-Coffee, green tea, matcha, Indian spiced chai
-Occasionaly mix supergreen powder mix in water and guzzle it down
-Don't drink alcohol
Activity wise, I've let myself go, but try to:
-Walk a lot
-Lift weights 3 times a week
-I occasionly jog (need to do this more often).
-Try and get around 7 hour sleep, typically 12am-7am as it suits my bodyclock.
Wrote this up if there's a small chance it may help someone boost their general immunity.
