I take a few supplements, based on my understanding of health risks:
1. kelp or other Iodine source, since my thyroid function is on the low side of normal;
2. vitamin D, since I need to limit sun exposure on my freckled Celtic skin to avoid melanoma;
3. saw palmetto or beta sitosterol, which has almost completely eliminated my BPH symptoms;
4. turmeric (which I also include in the diet), a known anti-inflammatory;
5. zinc, particularly when I feel a cold or flu coming on or when I have canker sores;
6. daily sublingual B12, as a dietary hedge;
7. lutein or lutein-containing "vision supplements," which my ophthalmologist strongly recommends for everyone.
For what it's worth, my ophthalmologist has observed a steady decline in the rates of both forms of macular degeneration over the four decades he has been practicing medicine, and he attributes this to the use of general vitamin supplements.
