Liver Helper Myth Destroyed

<Posted by dsaghafi> Like Gman has already mentioned, cranberry does not have any known renal protective properties. Gman might have used GNC as his source, but that is also what the literature (medline, pubmed,...) will show. Cranberry only hepls UTIs.
Dsaghafi (and everyone else) check this out. Doesn't look too good for cranberry juice - especially if you are taking something hard on your kidneys!

BTW, I couldn't find a single reference to cranberry having any positive effects for the kidneys.

Abstract
OBJECTIVES: Cranberry juice has been recommended for patients with recurrent urinary tract infections. However, cranberry juice has a moderately high concentration of oxalate, a common component of kidney stones, and should be limited in patients with a history of nephrolithiasis. Cranberry concentrate tablets are currently available at nutrition stores and are sold as promoters of urinary tract health. After one of our patients with a distant history of calcium oxalate nephrolithiasis developed recurrent stones following self-administration of cranberry concentrate tablets, we sought to investigate the potential lithogenic properties of cranberry supplements. METHODS: Five healthy volunteers on a normal diet provided 24-hour urine collection for pH, volume, creatinine, oxalate, calcium, phosphate, uric acid, sodium, citrate, magnesium, and potassium. Cranberry tablets were administered to these volunteers at the manufacturer's recommended dosage for 7 days. On the seventh day, a second 24-hour urine collection was obtained. RESULTS: The urinary oxalate levels in the volunteers significantly increased (P = 0.01) by an average of 43.4% while receiving cranberry tablets. The excretion of potential lithogenic ions calcium, phosphate, and sodium also increased. However, inhibitors of stone formation, magnesium and potassium, rose as well. CONCLUSIONS: Cranberry concentrate tablets are marketed for urinary tract ailments. Physicians and manufacturers of cranberry products should make an effort to educate patients at risk for nephrolithiasis against ingestion of these dietary supplements.

Yep. I read that one too.
But, lets be fair. Who's going to be up and about with half-a
-dozen couple of kidney stones in their kidney.

And, some of you are still not seeing the point of my post(Which
I thought I made clear enough)

ALA is to be taken. PERIOD.

Milk Thistle is NOTHING compared to ALA.

ALA does the same things Milk Thistle does(and more).

If ALA is taken, Milk Thistle will not strengthen your liver
any more.

So, if ALA already does what MT does, and MT will not
strngthen your liver any more than ALA does,
then what on earth is the bloody point of taking
Milk Thistle?

Good, bad, or indifferent, this is a perfect example of
how one throws his/her money away without
rea;izing it.

Fonz,

How about the effect Milk Thistle has on D-bol pains (ie lower back pain, etc). I've heard a lot of bros on this board swear by it.

Thoughts?
Fonz altho i reccommend ALA always.....milk thistle does stop back pain caused by Dbol-Peroid!!!! RADAR
 
Silent Method, the only problem with those research publications is that they don't say HOW helpful the MT is. Remember, the term "significant" is a scientific term of statistical probability, not a judgement on how effective something is. all that means is that it had *any* effect whatsoever which is not likely due to chance. Even a crappy result would still be called "significant."

I want MT to work, too, because silymarin can be bought cheap at dpsnutrtion.

I found this:

From the Harvard Health Letter:

Q: My neighbor takes something called milk thistle. He likes to drink alcohol and believes the herb will protect him against any kind of liver damage. Is he right?

A: Milk thistle is an herbal medication that has been used since antiquity for a variety of ailments, including snakebites and varicose veins, but most commonly for liver disease. It’s one of the few herbal medications that has been studied extensively. Six studies have evaluated milk thistle to see whether it helps patients with damage to their livers from alcohol. Most, but not all, have shown that some aspects of liver function improve, but it isn’t a consistent pattern. Results have been mixed in viral hepatitis and other liver conditions.

Results like these usually mean that a medication has only mild benefits, if any. Moreover, these studies don’t address the issue of whether milk thistle actually protects the liver, only if it might help people after the damage has been done. Your neighbor shouldn’t be so sure that milk thistle is going to save him from liver problems. Besides, having more than 1–2 alcoholic drinks per day carries health risks for anybody. Think about all those extra calories. Milk thistle probably won’t hurt him, but if it gives a false sense of security about a heavy drinking habit, it might.

I just read the abstract. It found moderate and distinct results in two measurements, but at very high doses.

These two aren't available. They're Italian and too old to be archived.

This study found the effect to be "significant," but the abstract did not specify what significance. Significance can be excellent or poor, just as long as *something* happens. I wish I had better info on this study.


A study that is very current at Saller R , Meier R , Brignoli R. "The use of silymarin in the treatment of liver diseases." Drugs, 61(14): 2035-63, 2001 found that "The available trials in patients with toxic (e.g. solvents) or iatrogenic (e.g. antispychotic or tacrine) liver diseases, which are mostly outdated and underpowered, do not enable any valid conclusions to be drawn on the value of silymarin."

"The exception is an improved clinical tolerance of tacrine. In spite of some positive results in patients with acute viral hepatitis, no formally valid conclusion can be drawn regarding the value of silymarin in the treatment of these infections...Therefore, silymarin may be of use as an adjuvant in the therapy of alcoholic liver disease."

In one trial of 602 patients, "The evidence shows that, compared with placebo, silymarin produces a nonsignificant reduction of total mortality..."

This study began with a review of 525 previous references, and concluded that the overal effect of silmarin was...well, not much.

The good news is that of all herbal remedies examined, only milk thistle was NOT hepatotoxic.
 
Fonz, your saying ALA works in exactly the same way as milk thistle - only better. You suggest NO overlap in the way in which they work. I don't buy it and I don't think their is any basis for the idea. No offense, but are you just pulling this stuff out of your ass? You have given no supporting evidence to your claims.

ALA IS a much more potent antioxident than milk thistle. However, take a look at those studies I posted. Milk thistle works by many mechanisms, some of which I'm sure we don't know. Same with ALA. But they do not do the same thing. Upon what do you base the claims that "Milk Thistle is NOTHING compared to ALA, ALA does the same things Milk Thistle does, if ALA is taken, Milk Thistle will not strengthen your liver
any more?"


Here is an abstract on the pharmacology of ALA.
The pharmacology of the antioxidant lipoic acid.

Abstract
1. Lipoic acid is an example of an existing drug whose therapeutic effect has been related to its antioxidant activity. 2. Antioxidant activity is a relative concept: it depends on the kind of oxidative stress and the kind of oxidizable substrate (e.g., DNA, lipid, protein). 3. In vitro, the final antioxidant activity of lipoic acid is determined by its concentration and by its antioxidant properties. Four antioxidant properties of lipoic acid have been studied: its metal chelating capacity, its ability to scavenge reactive oxygen species (ROS), its ability to regenerate endogenous antioxidants and its ability to repair oxidative damage. 4. Dihydrolipoic acid (DHLA), formed by reduction of lipoic acid, has more antioxidant properties than does lipoic acid. Both DHLA and lipoic acid have metal-chelating capacity and scavenge ROS, whereas only DHLA is able to regenerate endogenous antioxidants and to repair oxidative damage. 5. As a metal chelator, lipoic acid was shown to provide antioxidant activity by chelating Fe2+ and Cu2+; DHLA can do so by chelating Cd2+. 6. As scavengers of ROS, lipoic acid and DHLA display antioxidant activity in most experiments, whereas, in particular cases, pro-oxidant activity has been observed. However, lipoic acid can act as an antioxidant against the pro-oxidant activity produced by DHLA. 7. DHLA has the capacity to regenerate the endogenous antioxidants vitamin E, vitamin C and glutathione. 8. DHLA can provide peptide methionine sulfoxide reductase with reducing equivalents. This enhances the repair of oxidatively damaged proteins such as alpha-1 antiprotease. 9. Through the lipoamide dehydrogenase-dependent reduction of lipoic acid, the cell can draw on its NADH pool for antioxidant activity additionally to its NADPH pool, which is usually consumed during oxidative stress. 10. Within drug-related antioxidant pharmacology, lipoic acid is a model compound that enhances understanding of the mode of action of antioxidants in drug therapy.

Look, if it's freezing cold outside and I have to stay outdoors all night, the first thing I want is a warm, thick, protective coat. But if I can, I'm sure as hell going to grab a hat! Milk thistle does seem to have benifit that ALA alone doesen't.

BTW, the point of the cranberry study was that if you got some stress on the kidneys, cranberry might be a very bad idea.

Welcome to science. No data is anything but a statistical probability, some stronger than others. When we see words such as significant, considerable, substantial, etc, we can guage the strength of that probability. BTW, these are abstracts I'm posting. If I wanted quantified data for most of these I'd have to spring a few bucks for the whole report.

I don't think you have to quote some ALA research to me. I've seen
pretty much all of it. 4+ years of taking it sort of does that.... :)

I see were you're coming from BUT while Milk Thistle might
work through other pathways, these pathways are so minor
that ultimately they will factour out as irrelevant.
There are basically 2 phases to liver processing. You cover
them both and you're set. ALA does this TOTALLY. So, again
whats the benefit of MT if ALA already covers all the
important pathways?

Fonz
 
how about we stop this perpetual debate and just settle on taking BOTH ALA and MT if it suits some.....others can toss it if money is THAT much of an issue.

it's like you either believe in creationism or evolution. why can't we just believe in both? :D
 
OK I will bite and do some ALA with my next winny and also invest in stock of companies selling this supplement now that the Fonz has spoken :P

Anyway do you recommend any particular brands of this stuff?


Thanks!
