I just thought of this the other day. Since I'm now lactose intolerant, dose it reduce or even take away my lactic acid??

While the spelling might be similar, these are two separate processes. Your body (intolerance) cannot break down lactose, a sugar found in milk. Lactic acid is a byproduct of energy metabolism, where the buildup in muscles make you feel sore after a strenuous workout. So short answer is No.

As Soma said, just because they sound the same does not mean that there is any relationship. Lactose intolerance is the lack of the enzyme lactase which splits lactose (a disaccharide) into its component parts which are absorbed by the gut. If the lactose is not split and absorbed, the gut bacteria have a field day with the food source which produces gas and bloating and that is what produces the discomfort (medical jargon for pain).

Lactic acid is entirely different. Normally glucose is converted into H20 and O2 producing ATP (energy your cells can use). If you are exercising really hard, your cells do not have the ability to burn all of the glucose so it produces energy by converting glucose into lactic acid with a little ATP. There is almost no limit to that but it can not be sustained very long (like 30 seconds). I don't know if the limiting factor is a depletion of available fuel or some minor toxic effects of lactic acid build up or some combination. Usually researchers say something like the area is not "well understood" which means "I don't know".

No. But I don't think milk products are too good for cycling performance anyway so even if you can tolerate them, I would try and minimise your intake.

Lactate ion is actually produced from pyruvate, which is a high-energy intermediate. When you're producing more pyruvate than you can process, it's enzymatically converted to lactate. Lactate is a high-energy molecule, rather than a waste. What's more: the accumulation of lactate ion in the blood merely corresponds to acidosis, rather than the production of lactic acid (rather than lactate ion) being the culprit. The protons come directly from the use of ATP.

I drink tons of a milk with cereal and have hundreds of thousands of unofficial road victories under my belt.

Milk, it does a body good.

Hundreds of thousands? Is that actually possible? Well I don't drink it and have a Cat1 road licence and Elite XC MTB, along with numerous podium finishes and a few wins here and there so I don't think it's required for good results Whatever works for you though, that's the most important thing. I know riders who drink it and do well and vice versa. Notice that some pro's mention that they avoid dairy. Plus, it's been linked to osteoperosis, despite the high calcium content.

WHAT??? Source please.

Well, just type it into google. But here you go;

Countries with the lowest dairy consuption have also been found to have the lowest occurence of osteoperosis.
