Multi vitamin & trace element supplementation useful ?
Adequate intake of certain nutrients is associated with a reduction in all-cause mortality when the nutrient source is foods, but not supplements, according to a new study.

*) What you won’t have
- No place enough for useful trace elements like Mg or K.
- At least minimum 2 tocopherols (only one: alpha) (vitamin E)
- You need the right fats to absorb the benefits of fat-soluble vitamins (A D E K).
- The right type of all vitamins if you don’t make a sharp search (cofactors or bioavailable)
*) What you should avoid - B-50 complex. Not the appropriate dosage (cancer risk). Ok for RDA or 2x/wk.
- Mn, Fe (interaction, pro-oxidant)
- Fillers such Polysorbate 80 (microbiote), titan dioxide (nanoparticules => brain), magnesium stearate (if digestion problems), acacia gum (microbiote), silica. The less additives possible.
- Excess ingredient: 400 mcg folic acid.
- Excess niacin (20-25 mg B3 is ok ; often 50 mg => Mind the kind. Ok for niacinamide / nicotinamide).
- Excess B6 if brain sensitive (20-25 mg B6 PLP is OK)
- Etc.
*) Monitor copper intake if taking non-stop vitamin B complex, if your intake is low or if you take a zinc supplement (same carrier). 1.5 mg Cu as RDA or 8-10 mg Zn.
Vitamins that are considered antagonistic to copper are shown in figure below [vitamin B6, A, C, B3, and B5]. Excessive intake of any one or combination of these vitamins can contribute to or exacerbate an existing copper deficiency."

*) What I would do when taking a supplement
B vitamins generally act synergistically. The other B vitamins – other than B1, B2 and B3 – will therefore also be present but just to avoid a deficiency. And the B9 and B12? Joker, at this stage (we haven't forgotten them).
*) What I would mind:
Too much of a good thing is bad.
In cure it would be probably beneficial. Or not every day if you know what to avoid. But I’ve seen so much people believing doing well while it was not appropriate.
In times of uncertainty, doing nothing will be more profitable. Or we limit ourselves to obvious deficiencies when there is a deficit in menus. Knowing that it will always be better to choose a food rather than a supplement.

*) Study led by Dr. Francis Collins. 2019
The researchers found the use of dietary supplements had no influence on mortality. People with adequate intake of vitamin A, vitamin K, magnesium, zinc, and copper were less likely to die. However, that relationship only held for nutrient intake from food consumption.

Note’s editor:
- There are biases in the study. E.g. the take of a high supplement Ca (1 000 mg).
- I do take supplement but I’ve made researches to avoid interaction and counterproductive behavior.
Out of context: I was declared at high risk last weekend for prostate cancer because I’m 71, don’t eat tomato 4x/wk and don’t exercise enough. So don’t follow blindly one source. Cross-check the information and do cures rather than taking a lot of supplements. A bit contradictory, I know. Too long to explain why here. - If you make a search, you’ll have to be able to separate the true from the false and are able to make a synthesis when the sources are apparently contradictory, not to mention the studies in which the conclusion does not reflect the findings established above in the body of the study (conclusion oriented or who advocates more research).
