There is not going to be too much lactose in any whey regardless. I understand what you are saying because it's the same with me. Once you drink milk for a while you get more and more 'reactive' to it so that even whey could irritate you sans the lactase enzyme. But there is going to be very little lactose in any whey and very little lactose, relatively speaking, in any medication as well.
On the other hand, I can drink too much milk and start to react but I never have a problem with most any whey at all except for some VERY cheap and bad concentrates (read very low protein percentage). And I am saying that I have no problem even if it is in the midst of not being able to handle regular milk.
Lactose intolerance you know is not an allergy and nobody is completely intolerant to lactose. It's all degrees. While you may be VERY intolerant others may be able to handle certain amounts for certain periods of time longer. There's not need for most to be paranoid and read labels like they are going to go into anaphylactic shock.
I am NOT saying that your point about ON's lactase enzyme isn't valid, what I am saying is that without any amount given we can never be sure for any one person if the lactase is doing anything or it's just a case of not reacting to whey. If there were a significant amount of the enzyme in there they would give a friggin amount! Sorry, I am tired of bullshit labelling on supplements so I'm being rantish.
it would be nice if they noted how much though
You're a lot more accepting than me! I think it is unpardonable to claim such and ingredient without giving a better indication of how much is in it. As an aside I looked at some of their other wheys (why do they need so many?) and they don't all seem to contain lactase.
It is also interesting to me that ON lists the potency of the lactase enzyme without giving the actual amount. It doesn't matter if it is the highest potency, which I think it is, if there is hardly any actual ingredient in it.
They list 100,000 FCC lactase units per gram, which is some damn powerful stuff. Say 1000 FCC units per gram will convert 99% of the lactose in one liter of milk at a specific temperature within 24 hours. This means that gram of the lactase enzyme (I'm pretty sure anyway) they use will beak down 99% of the lactose in one liter of milk within 24 hours. So in the case of a whey like this it should take relatively little of the enzyme per serving. But while this information is super for people buying enzymes to use in their products it tells the average consumer NOTHING. More likely listing the potency is simply their to confuse people into thinking "theres a lot of it". There could be .00000000001 grams of the stuff, lol. In other words "window dressing". However, if the lactase is really 100,000 FCC units then one one hundredth of a gram should do the same job as the 1000 FCC example I gave, IF it actually reaches the small intestine in an active form, which is why supplements have a LOT of lactase in them, so that enough gets through to do some good. This is why you won't find lactase mixed with other enzymes. There is no room.
Does this mean I start with 10 grams (Dextrose/sucrose) & then sip the remaining(10gms) during the session?
Well let's rephrase all this.
You listed a shake "before" and "after" and "during". Before could mean 45 minutes to an hour before or it could mean immediately before. I was assuming because you have fruit for before and dextrose/sucrose for during that the before was "before" before.
For immediately pre-workout and during workout you can pretty much count them as the same thing but depending on whether you have a lot of carbs and how you react "pre" might need to mean about fifteen minutes pre. For the last few years I have dropped the pre and post workout thing for this and just say "around the workout".
If the before shake is like an hour before and is just there for the extra protein/calories then I would take that "during" shake and make it a big dilute shake. Drink half of it around fifteen minutes before you start the workout and sip the rest throughout. See how that feels.
Well I don't use to gain any muscle. I use it to neutralize the renal acid load(to prevent kidney stones) or is this assumption wrong?
Well first of all it's glutamic acid that has been associated with reducing or preventing kidney stones but glutamic acid (glutamate) and glutamine can be interconverted. Most diets get plenty of glutamic acid and it's not even an essential amino acid in the first place.
I don't know where you are getting the information from but it sounds like some kind of assumption that if you use whey or eat a lot of protein you will be in chronic metabolic acidosis. Even if that were true the key word would be "chronic" and the kidney's job is to respond to the acid-base status in the appropriate way. Yes, glutamine is used in the production of ammonium which supposedly has something to do with the excretion of excess H+ but it is not even clear how ammonium production and excretion means that excess acid is being excreted..there are theories. If you are in chronic acidosis and are therefore for related reasons prone to kidney stones it is probably related to the overall diet. Translate that as..eat your vegetables and leafy greens. But there is no reason to think that a high protein diet is going to give you kidney stones. They are very commonly associated with a "western" diet but why that is is not perfectly clear. Citrate is probably a better bet for a supplement if you think a supplement is needed but I'm not sure of the best form and it depends on what kind of stones. But since there is no reason to assume you will develop kidney stones….
