I've read mixed reports about this supplement so I've assumed it's a waste of money. This report suggests that it's useful for older people. I wonder if any of the old farts on this site have tried it.

"Old farts"...you must mean Tim, not me!

Stu, I spend a small fortune on supplements when I was younger. Now, I wait for other to try them and find out from them.

I have read some infomation on leucine being great. Have you tried it or heard anything about it?

Hey, Kenny, if the shoe fits, wear it.

Leucine, of course, is the main ingredient in BCAAs. I generally stay away from any unproven stuff just because I'm cheap. Whey, creatine, and fish oil is about all I've used. I'm like you, I'd rather wait for others to try stuff first.

btw, I wasn't trying to adress anyone in particular with the "old farts" comment but it's interesting to see who responded.

That's an interesting article. Almost everything on line about B-alanine is either on a site that sells it, or a site devoted exclusively to promoting it (and I can't imagine a reason to create such a site if you did't have a vested interest in selling it). Althought this is essentially a news article, and can't be guaranteed to accurately interpret the study (I haven't tracked down the study itself) it reports a double-blind, placeby-controlled study of a reasonably size, a rarity in the area of dietary supplements. It leads me to take it seriously. I'll probably try it next year when I'm back in the US.

I have a study that I can send any of you if you want regarding beta-alanine supplementation.

Short-duration β-alanine supplementation increases training volume and reduces subjective feelings of fatigue in college football players

Received 8 August 2007; revised 16 November 2007; accepted 16 November 2007. Available online 15 January 2008.

Abstract
The purpose of this study was to examine the effect of 30 days of β-alanine supplementation in collegiate football players on anaerobic performance measures. Subjects were randomly divided into a supplement (β-alanine group [BA], 4.5 g·d−1 of β-alanine) or placebo (placebo group [P], 4.5 g·d−1 of maltodextrin) group. Supplementation began 3 weeks before preseason football training camp and continued for an additional 9 days during camp. Performance measures included a 60-second Wingate anaerobic power test and 3 line drills (200-yd shuttle runs with a 2-minute rest between sprints) assessed on day 1 of training camp. Training logs recorded resistance training volumes, and subjects completed questionnaires on subjective feelings of soreness, fatigue, and practice intensity. No difference was seen in fatigue rate in the line drill, but a trend (P = .07) was observed for a lower fatigue rate for BA compared with P during the Wingate anaerobic power test. A significantly higher training volume was seen for BA in the bench press exercise, and a trend (P = .09) for a greater training volume was seen for all resistance exercise sessions. In addition, subjective feelings of fatigue were significantly lower for BA than P. In conclusion, despite a trend toward lower fatigue rates during 60 seconds of maximal exercise, 3 weeks of β-alanine supplementation did not result in significant improvements in fatigue rates during high-intensity anaerobic exercise. However, higher training volumes and lower subjective feelings of fatigue in BA indicated that as duration of supplementation continued, the efficacy of β-alanine supplementation in highly trained athletes became apparent.

EFFECTS OF TWENTY-EIGHT DAYS OF BETA-ALANINE AND CREATINE MONOHYDRATE SUPPLEMENTATION ON THE PHYSICAL WORKING CAPACITY AT NEUROMUSCULAR FATIGUE THRESHOLD.


The purpose of this study was to examine the effects of 28 days of beta-alanine (b-Ala) and creatine monohydrate (CrM) supplementation on the onset of neuromuscular fatigue by using the physical working capacity at neuromuscular fatigue threshold (PWC<sub>FT</sub>) test in untrained men. Fifty-one men (mean age ± SD - 24.5 ± 5.3 years) volunteered to participate in this 28-day, double-blind, placebo-controlled study and were randomly assigned to 1 of 4 groups: placebo (PLA; 34 g dextrose; n = 13), CrM (5.25 g CrM plus 34 g dextrose; n = 12), b-Ala (1.6 g b-Ala plus 34 g of dextrose; n = 12), or b-Ala plus CrM (CrBA; 5.25 g CrM plus 1.6 g b-Ala plus 34 g dextrose; n = 14). The supplement was ingested 4 times per day for 6 consecutive days, then twice per day for 22 days before posttesting. Before and after the supplementation, subjects performed a continuous incremental cycle ergometry test while a surface electromyographic signal was recorded from the vastus lateralis muscle to determine PWC<sub>FT</sub>. The adjusted mean posttest PWC<sub>FT</sub> values (covaried for pretest PWC<sub>FT</sub> values) for the b-Ala and CrBA groups were greater than those for the PLA group (p ≤ 0.05). However, there were no differences between the CrM vs. PLA. CrBA vs. b-Ala, CrM vs. b-Ala, or CrM vs. CrBA groups (p > 0.05). These findings suggested that b-Ala supplementation may delay the (reset of neuromuscular fatigue. Furthermore, there appeared to be no additive or unique effects of CrM vs. b-Ala alone on PWC<sub>FT</sub>.

From what I've read about you I thought you were early/mid-40s so not sure the study will be helpful to you as it seems to have involved a fairly small population (mainly female) of significantly more senior people. => http://www.jissn.com/content/5/1/21

Alas, I fall withing the range of their study population. Again this reinforces my plan to give this a try when I get to a place where I can get some at a reasonable price, and from a presumably reliable source.

Thanks. I can't tell how many tablets per bottle. I'll probably check several sources when I'm in the US next year. Don't want to pay for shipping to PNG!

It's a powder and it has to be measured out.
