This Journal Loves Zinc

From eNewsletter 8/4/2026

DID YOU KNOW that seven recent studies, all published in Frontiers in Nutrition, laud the myriad benefits of zinc or lack thereof. It is apparent that this journal is doing its due diligence on zinc!

Atrial Fibrillation

Zinc deficiency may serve as an important independent risk factor for incident AFib.

Dementia

Zinc deficiency represents an independent, modifiable risk factor for new-onset dementia.

Intracerebral Hemorrhage

Zinc deficiency is a novel, independent, and potentially modifiable risk factor for ICH.

Oral Cavity and Teeth

One study found that zinc deficiency impairs antioxidant defenses for oral cavity cancer. Another study found that dietary zinc intake reduces the risk of hypertension in periodontitis patients.

COVID-19

Zinc deficiency was observed in 28.6% of children with COVID-19 and was not dependent on age.

Cognitive Impairment

Higher plasma zinc levels and higher zinc/copper ratio were associated with lower odds of mild cognitive impairment in type 2 diabetes patients, while higher copper levels alone increased the risk.

NOTE: managing your zinc/copper ratios, with zinc being higher than copper (but you still need some copper), is essential.

The Incredible Gut Helper

From eNewsletter 8/3/2026

DID YOU KNOW that among the many systemic benefits of saccharomyces boulardii, a recent study from Burns and Trauma found it helpful for severe pancreatitis?

Patients with severe acute pancreatitis were randomized to S. boulardii (a beneficial yeast) plus enteral nutrition versus enteral nutrition alone. The rationale was that infections in these patients are frequently driven by impaired intestinal barrier function that facilitates bacterial translocation.

S. boulardii combined with enteral nutrition reduced infections and stabilized intestinal and respiratory microbiota composition while enteral nutrition alone did not.

For those of you who may not know, the main ingredient in UltraFlora Acute Care is S. boulardii. It is the most universally helpful gut supplement we recommend.

Improve Focus Naturally

From eNewsletter 7/29/2026

DID YOU KNOW that the combination of caffeine and L-theanine are a great combination for focus, energetic calm, cognition and mood, and can act as a natural alternative to attention deficit stimulant medication?

A double-blind, placebo-controlled study from the British Journal of Nutrition found that a high-dose L-theanine-caffeine combination (200 mg L-theanine and 160 mg. caffeine) improves neurobehavioral and neurophysiological measures of selective attention in acutely sleep-deprived young adults.

Another study from Nutrition Reviews found that L-theanine with caffeine can be beneficial for cognitive and mood outcomes.
