Zac’s video is here: https://www.youtube.com/watch?v=5N4kDHhqG0I
In it he makes the point that unless a supplement “moved the marker” that it was supposed to affect it was not worth spending money on it.
He had blood tests done over the course of a year and had them interpreted by a doctor to determine if the supplements he was taking affected the tested markers.
Trouble is, there might be less than 20 vitamins and less than 100 minerals but there are over 40,000 phytonutrients, only 10,000 of whiuch have been identified. And we have identified many health benefits that acrue from those phytonutrients. They were not on Zac’s list of markers to test.
And we still have no widely use test for mitochondrial function. (Mitochondria are the engines in our cells that produce energy. One of the problems people are suffering from post-Covid gene therapy shots is low energy.)
All in all Zac’s video may or may not have some data valid to his circumstances but it leaves a lot of data out of the equation.
I was reminded of this most stronly two hours after watching his video when I read this:
“Overall, most of these organizations recommend a minimum of 250–500 mg combined EPA and DHA each day for healthy adults. This can be obtained from about 8 ounces of fatty fish per week.
One study followed 11,000 people who took an 850-mg dose of combined EPA and DHA every day for 3.5 years. They experienced a 25% reduction in heart attacks and a 45% reduction in sudden death .”(https://www.healthline.com/nutrition/how-much-omega-3).
Heart attacks are a downstream effect (one of a great many) not catered for in Zac’s simplistic assessment of supplements.
