Supplements and advice please

[Serena1977]

Hi there,
I'm off to Holland and barrett to buy some supplements but which?

I'm perimenopausal, trainee teacher so busy, brain fog, tired all the time, post covid, don't sleep well, loads of dreams.
Blood tests all show just acceptable range except folate which I get prescription for.

Any advice or supplements recommended please?

At the moment I'm mixing and matching Vitabiotics Wellwoman Vegan (seems to cover everything in 2 tabs a day), Together omega 3 (algae oil - H&B do their own but it's always out of stock), sea buckthorn and (Wild Earth) vegan vit D3
