So far I'm just hoping the BetterTouchTool option pans out.
They're mostly designed to be ordered by a healthcare professional, but you can get a few of them direct on Amazon, or through companies that order on your behalf (similar to healthlabs.com mentioned above).
Quest-only: DirectLabs, Personalabs
Choice of Quest or DirectLabs: Walk-in Lab (switch the radio button to Quest on the category pages, and make sure a "QD" icon shows up next to it in your cart), TrueHealthLabs (make sure the tests you look at say Quest is an option), HealthTestsDirect (make sure the test list page is toggled to Quest at the top)
DirectLabs and Walk-in are generally cheaper than the others I mentioned.
I specifically use Life Extension for vitamin D because they're the cheapest one I'm aware of.
I've considered switching to frozen concentrate for a lower-cost approach. I think it's likely to be promptly frozen after harvest, and may have lower pesticide levels due to smaller-scale production: http://www.inspection.gc.ca/food/chemical-residues-microbiol...
The idea is that some types of problems are best solved with the focus you can provide at your peak times of day. However, "insight" problems might benefit from the reduced focus you have at non-peak times.
