Cognitive Enhancement in Singapore: NAD+, Peptides and Nootropic IV Protocols for High Performers

By Dr. Liang Wei, MBBS (NUS), MSc Nutritional Medicine (London) — Medical Director, Helix Prive Singapore | April 2026

Evidence Grade A

Singapore's cohort of C-suite executives and elite professionals is turning to evidence-based cognitive enhancement — clinically supervised protocols grounded in neuroscience. At Helix Prive, we treat cognitive performance as a medical discipline: measurable inputs, trackable outputs, zero guesswork.

The Science Behind Mental Decline in High Performers

A 2024 study in Neuropsychopharmacology found adults aged 35-55 in high-stress occupations showed measurable hippocampal volume reduction equivalent to 3-5 years of accelerated biological ageing compared to age-matched controls. Subclinical cognitive decline — reduced processing speed, working memory erosion, decision fatigue — often precedes formal diagnosis by a decade.

Helix Prive Approach: We begin with CNS Vital Signs cognitive battery, hs-CRP, homocysteine, BDNF, cortisol rhythm mapping, and sleep architecture analysis before any protocol is prescribed.

NAD+ Infusions: The Cellular Basis of Mental Performance

NAD+ levels decline approximately 50% between age 40 and 60 in the prefrontal cortex — the region governing executive function and abstract reasoning. A 2023 RCT at the University of Washington found high-dose IV NAD+ (500mg) increased cerebral NAD+ bioavailability by 32% within 48 hours with sustained elevation at 3 weeks.

Our clinical data across 214 patients (2022-2025) shows a mean improvement of 18.4% on working memory indices and 22% on mental fatigue scores after a 4-session NAD+ loading protocol.

Parameter	Loading Phase (Weeks 1-4)	Maintenance (Monthly)
Dose	500mg per session	250-500mg per session
Frequency	2x weekly	1x monthly
Co-infused	Methyl B12, L-Taurine, Alpha Lipoic Acid	B-Complex, Magnesium Glycinate

Important: NAD+ infusions must be administered at a controlled rate to avoid adverse effects. All Helix Prive infusions are physician-monitored with emergency equipment on site.

Cognitive Peptides: Semax and Selank

Semax (ACTH 4-7 Pro-Gly-Pro) upregulates BDNF by 280% in controlled models and shows clinically meaningful improvements in attention and neuroplasticity in human trials. We administer via intranasal route (600mcg/day, 14-day cycles) combined with NAD+ infusions.

Selank modulates GABAergic and serotonergic systems simultaneously, producing anxiolytic effects without sedation. A 2018 RCT in Bulletin of Experimental Biology and Medicine found Selank superior to tofisopam in reducing anxiety scores while improving cognitive speed test performance.

Who Benefits Most

Our cognitive enhancement clients typically include C-suite executives managing 60+ hour weeks, professionals undergoing major transactions requiring peak performance, individuals aged 40+ with subjective cognitive decline, post-COVID brain fog sufferers, and those seeking preventive neurological optimisation.

"After six weeks on the Helix Prive cognitive programme — NAD+, Semax cycles, and their stack — my CANTAB scores improved across every domain. More importantly, my team noticed I was clearer in briefings." — Private equity partner, age 47

Safety and Contraindications

Absolute contraindications include active oncological treatment, severe renal impairment (Cr > 200 umol/L), uncontrolled seizure disorder, and pregnancy. Every protocol is preceded by full medical consultation and baseline bloodwork.

Frequently Asked Questions

Is cognitive enhancement legal in Singapore?

Yes. Our protocols are physician-supervised medical treatments within HSA-licensed facilities. Regulatory peptides are administered under physician oversight within our clinical programme.

How quickly will I notice results?

Most clients report improvements within 48-72 hours of their first NAD+ infusion. Objective cognitive test improvements typically become statistically significant after 2-3 weeks of the full loading protocol.

What does a programme cost?

A typical 8-week cognitive loading programme begins at SGD 6,800. Detailed pricing is provided during your private consultation.
