TNutra Debuts NeuraLegend Brain Health System Built Around Cognizin® Citicoline at Full Clinically Studied Dose

Chemist-founded brand pairs a caffeine-free AM formula with daily Core and PM formulas designed to work together in support of healthy brain aging 

NEW YORK, Oct. 20, 2026 /PRNewswire/ -- TNutra™, founded by chemist Kevin Palmer, today announced the NeuraLegend™ system, a three-part daily brain health regimen anchored by NeuraLegend AM, which features 500 mg of Cognizin® Citicoline, the patented, clinically studied citicoline from Kyowa Hakko. The system is now available at tnutra.com. 

The three-part daily brain health regimen from TNutra contains: 

• Morning: NeuraLegend AM- containing Cognizin® 
• Afternoon: NeuraLegend Core- containing ErinaPrime®
• Evening: NeuraLegend PM- containing PharmaGABA®

Palmer created NeuraLegend after watching his grandmother, who largely raised him, slowly decline in a nursing home. "At the time, I didn't know enough to really help her," said Palmer. "I built this product line for myself and my family, and I think it's good enough to share with the rest of the world." 

Palmer creates and tests every formula, and his wife, Dr. Deborah Palmer, D.O., a family physician and Chief Medical Officer, reviews each one. "If it's not something we'd trust the people we care about most, it won't make its way into our formulas," he added. 

NeuraLegend AM delivers 500 mg of Cognizin in two caffeine-free capsules, the dose linked to episodic memory improvements in research involving healthy older adults with age-associated memory impairment. It pairs Cognizin with 200 mg of Suntheanine® L-theanine and 300 mg of enXtra® to support attention, working memory, sustained mental energy, and healthy brain energy metabolism in healthy adults.* 

"TNutra is formulating the way we hope every Cognizin brand will, with the full clinically studied dose and real transparency about every capsule," said Katie Emerson, PhD(c), RD, CISSN, Senior Manager of Scientific Affairs at Kyowa Hakko USA. 

NeuraLegend Core is one capsule a day containing 500 mg of ErinaPrime™, a pure, freeze-dried lion's mane mycelium from Grape King Bio standardized to 5 mg of erinacine A. Core supports nerve growth factor production, healthy BDNF levels, and cognitive performance in healthy adults.* 

The melatonin-free NeuraLegend PM combines 250 mg of reduced glutathione, 160 mg of GABA as PharmaGABA®, and 200 mg of Suntheanine to support healthy sleep quality and sleep onset in healthy adults with occasional sleep difficulties, as well as relaxation and the body's natural antioxidant defenses.*

Every NeuraLegend formula uses branded, clinically studied ingredients at full research doses, with no proprietary blends, no flow agents or fillers, and no more than two capsules per serving. Ingredients come from Japan, Korea, Taiwan, and India, and finished products are made in the United States. Each formula retails for $99, and the full system is available for $219, with subscription pricing available.
