It looks like you're only taking 500 mg of ALCAR daily. I would recommend increasing your total daily dosage to about 2.5 to 3 grams (in divided dosages). You should also be taking extra biotin (it's inexpensive).
Given the present controversy over different forms of nicacin, I would recommend adding 500mg daily of inositol hexanicotinate, and maybe eventually switching to the low niacin LEF mix when it comes time to reorder. Harvard scientists reported that nicotinamide supplementation in yeast was equivalent to a Sir2 deletion (decreasing lifespan), while the inositol hexanicotinate may do the opposite (increasing lifespan). These observations have recently been extended to worms, and are suspected to apply to mammals as well, although this remains to be proven. Alternatively, you could add the Longevinex resveratrol supplement to your program which supposedly activates the gene regardless. See:
http://www.longevinex.com (Longevinex should be taken along with 500 mg of quercetin to inhibit conjugation).
I would also add an extra gram of pantothenic acid in the form of calcium pantothenate daily. Both calcium pantothenate and inositol hexanicotinate are available in powder form at

There are dozens of other supplements you could add, of course.
If you want to see an example of a more comprehensive supplement program, you might want to take a look at Paul Wakfer's program at
