Which ISO do I use?

Use whatever ISO you need to get sufficient shutter speed and lens aperture.
Set the speed or aperture as you want for whatever your doing.
From your basic camera metering or a test shot, adjust the ISO value from the lowest to a higher value until the meter/exposure is where you want it. If the ISO value goes too high, get another lens or add lighting.

I was wondering which ISO to use on my Nikon D800? Supposedly the lowest native one (whatever that means). Currently I use 100 for most of my shooting. Could I go to Lo 1 or Lo 2 to get a better noise free image? Thanks in advance for the help.
ISO 100 or 200 will give you the best images.
The "Lo" ones are like the very high ones: not real ISOs but digital adjustments to the images. They generally increase noise. I only use the Lo ones when shooting waterfalls without my neutral density filter.
Up to 500 you won't see much noise on a D800, although if you shoot RAW you'll still want to do noise reduction in processing. Usually up to 1600 is pretty good, but above that you start seeing more visible noise to the extent that noise reduction will cost you detail.
At least that is my experience with my D800.

you can read all the books you want, and listen all of us who reply. in the end take your equipment to the different places and situations you shoot in and use trial and error to find what iso's work in your shooting situations. keep a log. there will be compromising. I was shooting birds feeding and incoming to my feeders today.;. there was no way I could get decent shots without going to 500-1200 iso, and that was with a 200mm f 2.8 G lens on a sony a-850 and a 1.4 teleconverter.

DxO labs does the most sophisticated digital camera testing. Do a search online for DxO labs camera sensor comparison tool. You can see the performance of up three cameras graphed on the same charts at the same time. I plugged in your D800. It looks like the highest signal to noise ratio is actually below ISO 100, probably about ISO 50. You can see the test results at different ISO's for a variety of factors such as dynamic range, signal to noise ratio, color sensitivity, and others.

ISO 100 is the best quality, and it will not be improved with the low range extensions. In fact, what the low range does is it diminishes the highlight headroom and adding it to the lower end. It's easier to blow highlights when you are using 50 ISO as opposed to 100 ISO.
