y0. I just joined here but I've been a member at the Hardforums for over 8 years (different name), and I've lurked this place for just as long.
Remember that your multivitamin will contain some chromium (probably also as picolinate or as polynicotate). You can supplement additional chromium, but I'd recommend backing down on the dosage. I use AOR orthocore (from either unique nutrition or relentless improvement) for reference. It is pricey, but it seems to have the best researched combination of ingredients. The Coq10, R-ALA, complete vitamin A/E profiles, and exclusion of SIRT1 inhibiting niacinamide (not a big deal unless you're a supplement nerd) are rare..
I'm not too keen on products like NOxplode, but if I were to use one I'd choose something like Millenium Sports "Ragnarok" (sold at nutraplanet) because of the superior ingredient profile and the inclusion of an antioxidant blend. One of the main objectives of these products is to boost Nitric Oxide production - which means increased free radicals and a need for antioxidants to protect from mitochondrial DNA damage (and other damage). Also: I'll admit that they do produce a good pump - they work.
Other than that... a High EPA/DHA fish oil (natural factors rx omega is a good one at iherb), and maybe acetyl L-carnitine (ALCAR) would help with fatty acid oxidation (based on the actual metabolic pathway for beta-oxidation which feeds directly into your krebs cycle). ALCAR can be dosed 2-3x daily at up to 500mg per dosage.
A good whey protein isolate is desirable. BCAA supplementation does help, but if you're getting enough protein then you can save your money unless you're really getting serious about this.
I do support the use of creatine, but don't overdose it. Your NoXplode already has it in there anyway.
About CLA: There are 2 primary isomers of this.
The trans10cis12 isomer is marketed for anti-obesity and anti-diabetic effects (and improved insulin sensitivity).
However, according to a randomized double-blind controlled trial (favorable test conditions I'd say), in obese men: "Unexpectedly, t10c12 CLA increased insulin resistance (19%; P < 0.01) and glycemia (4%; P < 0.001) and reduced HDL cholesterol (-4%; P < 0.01) compared with placebo, whereas body fat, sagittal abdominal diameter, and weight decreased versus baseline, but the difference was not significantly different from placebo. The CLA mixture did not change glucose metabolism, body composition, or weight compared with placebo but lowered HDL cholesterol (-2%; P < 0.05)."
Basically... this is bad, and the results have been reproduced (also in mice). It is not conclusive, however.
The cis-9,trans-11 isomer is next up (form included in most supplements / diet):
"RESULTS: ... Compared with placebo, c9,t11 CLA decreased insulin sensitivity by 15% (P < 0.05) and increased 8-iso-prostaglandin F(2alpha) and 15-keto-dihydro-prostaglandin F(2alpha) excretion by 50% (P < 0.01) and 15% (P < 0.05), respectively. The decreased insulin sensitivity was independent of changes in serum lipids, glycemia, body mass index, and body fat but was abolished after adjustment for changes in 8-iso-prostaglandin F(2alpha) concentrations. There were no differences between groups in body composition. CONCLUSIONS: A CLA preparation containing the purified c9,t11 CLA isomer increased insulin resistance and lipid peroxidation compared with placebo in obese men. Because c9,t11 CLA occurs in commercial supplements as well as in the diet, the present results should be confirmed in larger studies that also include women."
- again, this does not look good. It is also not conclusive.
I don't want to quote another study, but t10c12 was found to increase oxidative stress and inflammatory biomarkers in obese men, which seems closely related to the induced insulin resistance, suggesting a link between the fatty acid-induced lipid peroxidation seen in this study and the insuline resistance.
My advice: avoid CLA and stick with fish oil + ALCAR which have been proven effective. Unfortunately... marketing dominates many of the studies found in the supplement industry...
Side Note: there are a few conflicting studies suggesting induced chromosome damage from chromium picolinate (which is why some people prefer polynicotate), however the research is too lacking to suggest consistent mutagenicity.
Cliff Notes: I'd avoid CLA. I'd take whey protein isolate. I'd take a good multivitamin + high epa/dha fish oil + acetyl L-carnitine. Creatine is fine, and vasodilating (PUMPS) workout supplements are fine as long as you have some antioxidant protection. Additional chromium is probably fine, but I'd reduce the dosage to be on the safe side.
I'm sorry... as I said I'm a supplement-nerd (and a bit of nerd for all sciences). Please forgive the lack of brevity...
That's about it.
