Arginin?

[May-Linn Vorland]

Noen som vet om Arginin er bra for stress celler kolesterol blodfortynnende? Har hørt om at det skal vere bra for det hjerte og kar o.s.v.

Jeg har både pulverform og kaps, men på pulverformen står det ikke noe om doseringen og skal jeg bare blande det med vann tom mage...

Jeg tar 1 ts arginin på tom mage morgen kjveld og kanskje formiddagen

Spiser mye acai i pulverform C - vitaminer og sink multivitamin.

"A clinical trial found that patients taking an L-arginine supplement following a heart attack found no change in the heart's vascular tone or decrease in the symptoms of congestive heart failure (the heart's ability to pump). In fact, six more patients that were taking L-arginine died than those taking a placebo, resulting in early termination of the study with the recommendation that the supplement not be used by heart attack patients.[15][16] These findings suggest L-arginine is not beneficial post-heart-attack."

Når det kommer til stress, så var testen betalt av et firmal som produserer og selger arginin

"Dietary supplementation of L-arginine taken in combination with L-lysine has been shown potentially useful in treating people subjected to high levels of mental stress and anxiety, in a double-blind, placebo controlled and randomized study, involving 108 Japanese adults. Trait anxiety and state anxiety induced by cognitive stress battery was significantly reduced, and basal levels of the stress hormone cortisol were decreased. The study was funded by Ajinomoto, Co. Inc., an industrial manufacturer of lysine and arginine.[32]"

Arginin er en "betinget essensiell" aminosyre, så man skal ikke holde seg unna det. Men det er lite som egentlig tilsier at du skal bruke mye penger på å skaffe deg det.

Arginine

“NO supplements” containing arginine are consumed by bodybuilders pre-workout in an attempt to increase blood flow to the muscle during exercise, increase protein synthesis, and improve exercise performance. However, there is little scientific evidence to back these claims. Fahs et al.[

176] supplemented healthy young men with 7 g arginine or a placebo prior to exercise and observed no significant change in blood flow following exercise. Additionally, Tang et al. [177] supplemented either 10 g arginine or a placebo prior to exercise and found no significant increase in blood flow or protein synthesis following exercise. Moreover, arginine is a non essential amino acid and prior work has established that essential amino acids alone stimulate protein synthesis[178]. Based on these findings, it appears that arginine does not significantly increase blood flow or enhance protein synthesis following exercise.

The effects of arginine supplementation on performance are controversial. Approximately one-half of acute and chronic studies on arginine and exercise performance have found significant benefits with arginine supplementation, while the other one-half has found no significant benefits [

179]. Moreover, Greer et al. [180] found that arginine supplementation significantly reduced muscular endurance by 2–4 repetitions on chin up and push up endurance tests. Based on these results, the authors of a recent review concluded that arginine supplementation had little impact on exercise performance in healthy individuals [181]. Although the effects of arginine on blood flow, protein synthesis, and exercise performance require further investigation, dosages commonly consumed by athletes are well below the observed safe level of 20 g/d and do not appear to be harmful [182].
