Free online program begins November 3; Lewis’s November 7 session focuses on polysaccharides, with related guides helping readers evaluate brain supplements.
-- SOUTH MIAMI, Fla., November 1, 2026 — Nutrition researcher John E. Lewis, Ph.D., founder and president of Dr Lewis Nutrition®, will contribute to the Healing Dementia Summit 2026, hosted by Sharon Goldberg, MD, with a discussion of polysaccharides and their place in nutrition research.
Beginning November 3, the online summit presents ten days of interviews through November 12, followed by a November 13 bonus program drawn from its archives. Lewis’s November 7 interview is titled “Polysaccharides: The Overlooked Nutrient That Could Change Dementia Care Forever.”
The program brings Lewis into a wider discussion featuring David Perlmutter, MD, Dale Bredesen, MD, Heather Sandison, ND, and Jill Carnahan, MD. His interview appears on the same day’s schedule as nutrition author Patrick Holford, BSc.
For someone investigating brain health for a parent, a spouse, or themselves, a nutrition discussion can prompt two immediate decisions: which ideas deserve closer attention and how to evaluate products associated with those ideas. Alongside his summit participation, Lewis’s published consumer guides address the research and company information behind those decisions.
Attending the summit beginning November 3
The Healing Dementia Summit is online, with each day’s interviews available free for 24 hours. Registered participants receive access instructions by email and can watch on a computer, tablet, or smartphone. An optional paid VIP pass provides extended access.
The scheduled discussions cover nutrition, the gut microbiome, lifestyle, environmental factors, and emerging approaches to cognitive health. Participants can select sessions relevant to their interests rather than needing to follow every interview.
Registration, the full speaker list and schedule, and additional information are available on the summit website.
A nutrition researcher’s perspective on cognition
Lewis’s contribution draws on work examining nutrients and cognitive function. He was lead author of a 2021 narrative review in the Journal of Clinical and Translational Research that examined 96 human-study articles across 21 nutrient and phytonutrient categories, including aloe polysaccharides.
The review considered outcomes ranging from memory and attention to information processing and daily functioning. Its authors reported that findings varied across populations and health conditions, making the details of individual studies important to interpretation.
That breadth gives the summit topic context beyond a single ingredient. Nutrition research examines different compounds, combinations, people, and outcomes; understanding those distinctions helps connect an interesting interview to a more informed decision.
Lewis also founded Dr Lewis Nutrition®, whose flagship product is Daily Brain Care. His consumer resources connect his research background with practical standards for evaluating supplements, including the products offered by his own company.
Identifying research relevant to a brain supplement
For consumers evaluating a brain supplement, the useful evidence is research that matches the formulation, amount, population, and outcome being discussed. A study on one ingredient answers a different question from a study on a finished combination.
Lewis develops that distinction in his seven-question guide to evaluating brain supplements. The guide gives readers a practical starting point: identify what participants took, how much they took, how long they were followed, and what researchers actually measured.
It also distinguishes a noticeable stimulant effect from daily nutritional support. Feeling more alert shortly after taking a product does not, by itself, establish the broader benefit suggested by its marketing.
For families and individuals comparing options, those checks make research language more usable. Instead of relying on a label’s reference to science, readers can locate the underlying paper and see which conclusions it supports.
Evaluating the company behind the product
Choosing a supplement also involves assessing the company offering it. A named formulator, accessible research, clear product information, and responsive answers give consumers specific information to investigate.
Lewis’s guide to choosing a supplement brand applies that approach to laboratory testing, testimonials, formulation disclosure, and marketing claims. It encourages readers to examine his own company by the same standards.
For laboratory testing, the guide explains the value of identifying who performed the analysis and what was tested. Lewis reports that independent testing of his products covers heavy metals and microbiology, with redacted lot-specific certificates available on request. The scope of a test matters when interpreting what it establishes.
The two guides serve complementary purposes: one helps readers investigate the research behind a formula, while the other helps them assess the business responsible for it. Both offer a way to continue investigating the nutrition questions raised by the summit.
The summit provides educational information and does not replace individual medical advice.
