The good docs in Oakland stressed the importance of zinc for thals. Thals are often deficient in zinc. Zinc has a role in many of the important processes in our bodies, for example the pancreas requires zinc to produce insulin, the bones require zinc to maintain a healthy bone density, the endocrine system and the nervous system all require zinc. Ensure you are taking a multivitamin with 100% of the daily recommended zinc.
We were told that one should focus on getting a multi containing 100% of the daily recommended levels of zinc, vitamin C, vitamin D, vitamin E, calcium, magnesium etc.
Vitamin C was also stressed a lot - as well as vitamin D.
