Glutamin: Generelle Fragen & Einnahme-Empfehlungen?

[muskeltoni]

Ich habe viel mit Glutamin herumexperimentiert,vorzüglich in Phasen hoher Intensität im Ausdauerbereich und glaube,dass vor allem der GH-ausschüttenden Aspekte das Haupt-Plus der Glutaminsupplementierung ist,also alles was mehr als 4-8g sinnlos ist,da der Körper aus anderen Aminso wunderbar selbst Glutamin syntethisieren kann und dieses dann die Muskeln versorg.währedn über den Darm fast nichts in den Blutstrom gelangt.

Ich denke L-Glutamin tut einen fast so guten Job,wie Glutaminpeptid,auch wenn man schon einen Unterschied merkt,aber leider hauptsächlich im Preis.(obwohl das auch eher marginal ist,mit den richtigen Quellen)

L-Glutamin löst sich ausserdem besser auf.

Man kann nat. L-Glutamin und Peptid vorher trocken mischen,dann löst sich alles super auf nd hat auch ne suer Wirkung,sie sich am deutlichsten -oder fast nur-auf nüchternen Magen zeigt.

Und was ist mit Glutaminsäure?
Wie ist die zwischen L-Glutamin und Peptid einzuordnen?

Wie sieht es mit der Einnahme aus, wann hast du wieviel genommen?

Glutamin ist das Amid der Glutaminsäure (siehe unten). Zur Supplementierung ist Glutaminsäure zumindest für Deine Zwecke aber nicht geeignet (Vgl. auch >Glutamin Report<)

Noch ein paar Zitate aus der Fachliteratur:

Kreider (Sports Med 1999 Feb; 27 (2): 97-110):

Glutamine is a common ingredient currently found in many of the weight-gain supplements marketed to athletes. Glutamine is an amino acid which has been suggested to promote muscle growth and decrease exercise-induced immunosuppression.
These contentions are based on animal and human studies that investigated the effect of glutamine on protein synthesis, [23,24] cell volume[25] and glycogen synthesis.[26] Studies also suggest that intense exercise may decrease glutamine levels[27,28] and that this decrease may contribute to exercise-induced immunosuppression in overtrained athletes.[27-29]
In analysis of this literature, it appears that glutamine is an important metabolic nutrient affecting protein synthesis, [23,24] possibly by increasing cell volume and osmotic pressure.[25] Furthermore, glutamine availability directly affects lymphocytic function.[27-29] Branched-chain amino acid (4 to 16g) and/or glutamine supplementation (4 to 12g) has been shown to increase glutamine levels.[22,29]
Consequently, there is some evidence to support glutamine supplementation, in that it may promote muscle growth [23,24] and/or prevent upper respiratory tract infections among athletes.[22,27-29] However, long term studies investigating the effects of glutamine supplementation on protein synthesis, body composition, and the incidence of upper respiratory tract infections during resistance training have yet to be conducted. Consequently, although basic research is promising, additional research is necessary.

Kreider et al. (Sports Nutrition Review Journal. 1 (1):1-44, 2004.):

Glutamine is the most plentiful non-essential amino acid in the body and plays a number of important physiological roles 36. Glutamine has been reported to increase cell volume and stimulate protein 94- 96 and glycogen synthesis 97. Theoretically, glutamine supplementation prior to and/or following exercise (e.g., 6-10 g) may help to optimize cell hydration and protein synthesis during training leading to greater gains in muscle mass and strength 36, 98. In support of this hypothesis, a recent study by Colker and associates 99 found that subjects who supplemented their diet with glutamine (5 grams) and BCAA (3 grams) enriched whey protein during training promoted about a 2 pound greater gain in muscle mass and greater gains in strength than ingesting whey protein alone. Although more data is needed, there appears to be a strong scientific rationale and some preliminary evidence to indicate that glutamine may help build muscle.
