I've had some success with Dr. Danielle's Curcumin. It seems to help with the foggy headed feeling. I can attribute that to curcumin's anti-inflammatory properties. The formulation seems to aid in bioavailability which is important for certain molecules such as Curcumin.

I am awaiting the R-Alpha Lipoic Acid product from Dr. Danielle currently. Hoping to add it to my antioxidant stack in the morning. It, along with Acetyl-L-Carnitine and Ubiquinone (active form of Coq-10), has a reportedly synergistic effect: meaning they add to eachother in how much reaches the central nervous system.

Anyway, Dr. Danielle's products are a little over priced, as Mark hinted at, but if you can afford them, don't hesitate to purchase them. It should be noted that the company is fair and offers free second bottles with every purchase. You just have to write a review or join a mailing list.
