Then I'm reading a website about these tests you can get and they show you your vitamin and mineral needs.  It's pretty expensive however here's a sample report.

 

Seems good if it's legitimate, but basically this could be anything.

 

Do any of you desire to share what you know about these?

 

Given someone who has done testing at 23andme, would you have this same detail?  I did their big test and it has all the pairs or whatever laid out, but I don't recall it giving this much precision about nutrients.

Genetic tests can only show a slight probabilty of higher needs. For knowing your actual need only repeated blood-work will show the correct dose. In the example report thex talk for example about reduced conversion of beta-carotene to preformed vitamin A. To know that this probabilty is expressed in you, you still would have to test serum retinol, and then repeatedly to find the correct dose of retinol to circumvent that reduced conversion.

 

In the example report they talk about 30 such genes. Though some of those probabilties can be known to be expressed - or not - through direct observations or experimenting. You still would need to test directly in blood: homocysteine, methlymalonic acid, vitamin B6, omega-3 index, vitamin D3, retinol, microbiome, cholesterol-, thyroid-, androgen-, kidney-, liverenzymes-, electrolytes-, glucose-, CBC-panels, etc. - to find if a gene-mutation IS expressed, and repeatedly to titrate the correct doses of nutrients you need.

 

Therefore you can simply skip the gene-test, save its money for getting serious in assessing comprehensively your nutrient status by blood work. Which is essential to know your actual needs (a gene test can't tell). And bloody expensive if done repeately as is often needed in itself.

I'd say it's too early to invest in these things, especially if you've already paid for sequencing. Here's an independent take on these startup companies.  They point out the minimal data some recommendations are based on, and the sometimes suspect theories of aging. For instance, do you want to take supplements that lengthen your telomeres when telomeres have a such a poor correlation with aging?

I did one it felt very vague the recommendations and based on vague assumptions not specific enough even with my dna .

 

Another somewhat unrelated thought: So vitamins and minerals are absorbed to keep pathways activated in your body. But I have always wondered why your body just doesn't activate it without the need of them or produce them in large quantities? My theory is because of evolution. Your body changes with your diet and if you somehow had the ability to do it then your DNA would stop changing as fast and much. So something that then would be truly essential like Protein could be used to just produce whatever you needed. Because proteins, fats etc are absorbed very well outside of the small intestine. So I think the biggest purpose of the small intestine is to just absorb vitamins so it must be the newest organ or something in the human body, meaning it was developed late in comparison to other organs in the evolution. Or maybe to hold a lot of bacteria and that somehow changes you the bacteria.
