So to get back to the original question: This place here is crowded by extremely knowledgeable people that have a pretty clear picture of the current literature. So, what are your conclusions on the options in terms of drugs/supplements that REALLY make sense for extending life span? What are you actually taking yourself - if anything at all?
Here are my 10 cents: My personal philosophy is that life span extension is not everything, "health span" is as important. My supplement stack is adapted to this idea.
Background: I'm around 40 yo, lean, working out 2-3x a week. Non-smoker, no alcohol. I try to keep my caloric intake low, but it's not real CR. Blood work always looks very good so far (knocking on wood).
For >5yrs I'm on the following stack:
ED: 4000 IU Vitamin D (cognitive benefits & bone mineralization)
ED: ~1g of Vitamin C (immune function)
ED: 15mg Zinc gluconate (immune function)
ED: 750mg Glucosamine Sulfate (solid evidence for increasing LS & joint protection)
ED: 120mg Ginkgo Biloba (Mainly for cognitive benefits and neuroprotection)
EOD: EPA 465mg / DHA375 mg (cognitive benefits, but I also barely eat fish, this is for balancing my diet, I use Lovaza because I'm scared of heavy metals in fish oil)
5D per week: 500mg ALCAR (cognitive benefits and mito function, I exclusively use biosint branded sup's)
ED: 300-400mg caffeine from Coffee (Energy and neuroprotection)
To avoid potential impurities of health food supplements, all of the above, except for the ALCAR, are expensive pharmaceutically pure and standardized products.
Currently debating to lower antioxidants in the stack and to remove the EPA/DHA completely because of the Spindler papers.
Considering to add:
Metformin
Acetylsalicylic acid (anticoagulant effects may be too much with the Ginkgo)
Lipoic acid (played around with this already, but I get stomach troubles, may go for very low dose)
C60 Oil
Weat germ (for its spermidine content, but the potential for food allergy scares me)
