In your experiences, what are the most common nutritional/vitamin deficiencies you pick-up, which are missed on bloodwork by a physician?
There are quite a few that happen to be tricky to catch via blood work.
Let me first say I am not here to say blood work is shit and never do it. To each there own, we simply provide an alternative.
Calcium is one in particular that is hard to catch in blood work (at least accurately), what happens is that the blood will always try to remain in homeostasis, calcium ion channels are the mechanism in which our muscles move (heart pumps) so our body will do everything to keep blood levels stable, all the way up until death.
Your blood will actually leech calcium (and other nutrients) from your bones and other tissues so your blood calcium levels remain consistent. So you could be very low in calcium or even on the verge of osteoporosis yet your blood values remain "normal."
B6 and Zinc bind under stress (its referred to as the mauve factor) so many people experience flawed zinc and B6 values when getting blood work done simply do to the nature of visiting a doctor for some people.
Another problem is with the water soluble vitamins; a B12 deficiency for example can actually show up as misleadingly high levels of folic acid.
There are always inherent flaws when you try to pull bodily nutrients from 1 source. I tell my clients this, blood work is a Polaroid picture - a snapshot of one very brief moment in time. Usually you are asked to fast before getting blood work done. I see this as an issue because we dont't normally fast. So how can you expect your values to be normal if you aren't in a normal state yourself? Many of the water soluble vitamins will be excreted within the 12-16 hour window in which you have fasted as well.
I honestly created this company because this test worked exceedingly well for me and my clients. I have actually been using it for 12 years but just recently started this company to offer it to the public.
I would say the main reason that I prefer this (and it doesnt mean I never do bloodwork) but this covers far more nutrients than a blood test can. Blood tests simply can't catch everything and when I have looked into private labs to run a more comprehensive analysis it was upwards of $500.
