1. Key Global Benchmarks at a Glance

55 Million

People globally currently living with dementia; projected to reach 139 million by 2050.

Source: World Health Organization (WHO) Global Status Report

45%

Of dementia cases worldwide could theoretically be prevented or delayed by modifying 14 risk factors.

Source: Lancet Commission on Dementia Prevention (2024–2026)

90.6%

Of American adults do not meet the recommended dietary intake for choline (essential for acetylcholine synthesis).

Source: National Health and Nutrition Examination Survey (NHANES)

35.2%

Of working adults report sleeping fewer than 7 hours per night, impairing glymphatic beta-amyloid clearance.

2. Workplace Cognitive Fog & Attention Metrics

Knowledge workers experience significant cognitive fragmentation due to digital switching. Clinical attention benchmarks indicate:

47 Seconds: Average duration an office worker remains focused on a single screen before switching tasks or self-interrupting (Mark et al., University of California, Irvine).
23 Minutes, 15 Seconds: Average recovery latency required to return to deep focus following an unscheduled interruption.
$650 Billion: Estimated annual cost in lost productivity and cognitive fatigue across US organizations due to unaddressed daytime sleepiness and focus deficits (National Sleep Foundation).
13.6% Increase: Documented rise in brain cellular bioenergetics (ATP and phosphocreatine) in frontal cortex following standardized Cognizin Citicoline supplementation (Silveri et al., Harvard Medical School).

3. Neuro-Nutritional Deficiencies in Modern Populations

Modern dietary patterns show profound shortfalls in compounds vital for neuronal membrane fluidity and synaptic transmission:

Nutrient / Compound	Biological Brain Role	Population Inadequacy	Clinical Benchmark
Choline (CDP / Alpha-GPC)	Precursor to acetylcholine; cell membrane phospholipids	90.6% below AI	250–500mg daily
Omega-3 DHA	Structural component of cerebral cortex & retina	68% below optimal index	500–1,000mg DHA/EPA
Magnesium (L-Threonate)	NMDA receptor modulation & synaptic plasticity	52.2% below EAR	1,000–2,000mg Magtein
Vitamin D3	Neurosteroid gene expression & neuroprotection	41.6% deficient/insufficient	2,000–4,000 IU daily
