Zinc eaten at levels found in biofortified crops reduces 'wear and tear' on DNA - Science Daily, 1/3/17 - "a modest 4 milligrams of extra zinc a day in the diet can have a profound, positive impact on cellular health that helps fight infections and diseases. This amount of zinc is equivalent to what biofortified crops like zinc rice and zinc wheat can add to the diet of vulnerable, nutrient deficient populations ... Around much of the world, many households eat polished white rice or highly refined wheat or maize flours, which provide energy but do not provide enough essential micronutrients such as zinc. Zinc is an essential part of nearly 3,000 different proteins, and it impacts how these proteins regulate every cell in our body. In the absence of sufficient zinc, our ability to repair everyday wear and tear on our DNA is compromised" - See Jarrow Zinc Balance at Amazon.com.

Zinc-rich oysters as well as zinc yeast- and astaxanthin-enriched food improved sleep efficiency and sleep onset in a randomized controlled trial of healthy individuals - Mol Nutr Food Res. 2016 Dec 25 - "These subjects were divided into 4 groups: placebo, zinc-rich food, zinc- and astaxanthin-rich food, and placebo supplemented with zinc-enriched yeast and astaxanthin oil. Compared with the placebo group, the zinc-rich food group efficiently decreased the time necessary to fall asleep and improved sleep efficiency, whereas the group that ingested zinc-enriched yeast and astaxanthin oil significantly improved the sleep onset latency" - See Nutrex Hawaii BioAstin Hawaiian Astaxanthin, 120 Gel Caps supply, 4mg Astaxanthin per Serving and Jarrow Zinc Balance at Amazon.com.  Cut and paste from my 11/9/16 newsletter:

These included improvements in clarity of thinking, concentration, motivation, and mood. Irritation and feeling of body heaviness were reduced.
