I know the 7 keto DHEA is highly recommended in a lot of circles. It is much safer than regular DHEA which is a hormone precursor.
I am all for supplementing the diet but the recommendations can be overwhelming. It seems like all the experts have a list of recommended supplements, and the list quickly gets too long if you take the advise of several experts. If you have a doctor you trust and can talk supplements with them that's great. I've found that most doctors talk prescriptions and not supplements, and if they do talk supplements it is either very general (take a good multi-vitamin) or it is for one certain product they like.
I've been researching these things for a while. My doctor's have diagnosed me with chronic fatigue, which seems like a garbage can term for *ok, we don't know what's wrong with you*. Anyway this is the way I categorize supplementation:
Nutritional supplements - If we could all eat a completely balanced diet of raw organic foods, taken from soils that have not been depleted, and have zero stress in our lives, then we probably wouldn't need nutritional supplements. As it is most of us could benefit from these. I put multivitamins plus separate doses of the more bulky vitamins C, E, and calcium.
Lifestyle supplements - These include things to help with certain areas like stress, managing weight, helping with heavy physical training, women’s issues (pms, pre/menopause etc.) These would be higher doses of anti-oxidants, EFA’s, CLA, the amino acids, etc
Anti-aging supplements – These attempt to keep your body’s biochemistry younger than it is. Many chemical levels naturally decrease as we age, and supplementing these can help keep our bodies in a younger chemical state. These would be things like DHEA, CoQ10, and melatonin.
Oops, I think this is more than you were asking
