ALA is expensive?!? In the 80's, maybe, but it's not expensive anymore.
You can find it damn cheap online on many websites. Never buy it in powder, only in capsules, because the powder stuff degrades to I don't know what.
In that Cell Tech product, there is 75g of dextrose and 200mg of lipoic acid per 10g of creatine.
You can find 120*100mg of ALA easily for under 6$, and you can certainly have better deals if you buy the bigger capsules.
ALA is a very great antioxidant, especially if you're already supplementing with Vitamin C and E, as the three of them works in synergy.
Yes R-ALA is better than just ALA, but the S isomer of ALA is not bad, and you're better taking more ALA than buying the overpriced R-ALA.
