Need immune system tips that actually work!

I desperately need to boost my immune system, I work in a school and this year for some reason I just keep catching everything going! I’ve basically been ill every week since the start of September. This last week has been awful, I’ve been off work with a high temp, cold symptoms, sickness and a really painful neck (all at once not separately). I can’t seem to shift this one and keep feeling worse everyday rather than better.
About 6 months ago I really turned my life around, lost a lot of weight (am now a healthy bmi instead of obese), I’ve been eating really healthily, cut out all alcohol and have been exercising. I also started taking vitamin d, b12, vitamin c and omega 3. So realistically I should be at my healthiest, but I just can’t seem to kick any bug!
Has anyone got any tips of things that actually work?

The difference for me is taking vitamin C and zinc. I was ill constantly when I started working with young children. Also always wash your hands before eating, don’t touch your face or mouth unless you’ve washed your hands.

All you can do it diet, rest, and hygiene - everything else is conjecture

Eat good, clean (whole) foods for at least 80% of your diet.
Sleep well (6 hours minimum per night)
Stay hydrated.
If you are overweight, try to cut back on your calories or move more. Excess weight has been shown to put strain on the immune system.

I used to be constantly ill most winters, but since loosing weight I hardly ever get colds or flu, and when I do they are much milder.

I really feel for you. I've had those periods where it feels like you're constantly ill and it's so frustrating.

You're doing a lot of great stuff already so keep going. I honestly don't think there's a magic pill or supplement that boosts your immune system, you need a multi pronged approach like you're doing. There's no substitute for sleep though - as much as you can possibly manage, on a regular basis

Prioritise sleep as research does show poor sleep impacts immune function.

OP I have suppressed immunity because of the medication I am on. There is a great deal of rubbish talked about “boosting“ an immune system. Including by people who ought to know better because of their training.

Your immune system is just your immune system and can’t be turbo charged or somehow ramped up to give Protection ++. Those of us with autoimmune diseases are only too well aware of how an overactive immune system is damaging and causes health problems. You would not want that, believe me.

What you can do is protect against infection. I use a face mask and I use a nasal spray to protect against viruses. I also use a saline nasal flush. This has to be done daily. I wear the face mask on trains and buses. I use the nasal spray several times a day when I’m amongst crowds and I use the saline spray every evening. It is tedious and expensive.

It works but it is rather more basic, less exciting and definitely more effort than swallowing pills to, somehow and indefinably improve what an immune system does. It does work.

I suspect that this is not what you want to hear.

I was feeling like you from end of August onwards, seemed to be ill constantly. I've been taking high dose vitamin c, zinc and b vitamins on a daily basis and I seem to have turned a corner in the last 2-3 weeks.

Get a HEPA filter for your room at work!

The thing is once you get one bug your immune system seems to take a bashing and you get others more easily

the only thing that works for me is extra rest - so exercise but lightly , have an hour extra in bed ( cut the TV time) , cancel lots of weekend and evening plans and chill out

DH had a sickness/fever bug that lasted a good couple of weeks , some nasty things out there

congratulations on turning life around and doesn’t it suck when you get this in return - the long term benefits will be immense - hang on in there
