…………...Folken
Not sure that I would agree about the "double blind studies are lacking" part, Folken.
A Google Scholar search will provide more than a lifetime's reading of double blind and RCT trials on nutrients.
But even then you need to be careful.
For example, the recent very large 5 year trial that concluded there was no benefit in Vit D and/or Fish Oils on heart health or cancer.
They supplemented with such (embarrassingly) low doses that all it proved was that if you take almost nothing, what you'll get is.... almost nothing.
I share your suspicions around the benefits offered when there is no underlying deficiency. The trouble is that 'underlying deficiency' is
everywhere.
Yes yes yes, 'they say' a balanced diet will provide you with everything you need - but there's no consensus among Nutritionists about what a 'balanced diet' looks like.
Of course, virtually everyone agrees that lots of colorful vegetables is the
basis of a good diet (and throw out the sugar entirely) - but watch the heckles rise when you start asking specifics about the benefits of GMO grains, and what the levels should be for carbs, fats and protein.
I eat (what I consider to be) an
excellent diet. (The starting point being to cook as many of my own meals as is realistically possible).
Yeh - my diet is great - well, except over the recent Festive Season when it all went to pot

.
Even so, I will
still keep taking my multivitamin/mineral tab, Vit D3 & K2-7, magnesium, zinc, fish oils, K2-7, probitoics & prebiotics.
That's just what's right for me. Of course others are welcome to take - or
not take - what they feel is right for them.
I'm happy to spend my hard earned dollars on supplements, but, tbh, feel kind of disappointed that so many others choose to spend theirs on cigarettes and alcohol.
I would also finally add that discussing Nutrition/Supplementation is the same as talking about Sex, Politics and Religion.
It can be fun; it can also be fraught with difficulty (although unlikely to lead to war).
PS. The notion that 'vitamin enriched' gummy bears can replace vegetables gives me the heebie-jeebies.
