In the pursuit of high performance—physically, cognitively, and professionally—many executives are turning to supplements to gain an edge. But while supplementation is a key part of modern wellness routines, not all products are created equal, and not every benefit is backed by strong evidence.
From cellular health and cognitive resilience to muscle recovery and nutritional insurance, understanding what works and what is just marketing hype is essential for making informed, strategic decisions. Below, we examine four popular supplements through the lens of scientific evidence, executive relevance, and long-term wellbeing.
Creatine and Executive Function: Beyond the Gym
What is creatine used for?
Commonly used to support physical strength and recovery, creatine increases intramuscular energy reserves, helping improve short-duration, high-intensity performance [1]. Some emerging studies also suggest benefits for brain function, including improved mental fatigue resistance and possible neuroprotective effects [1].
Why it matters for executives
Executives operating under pressure may benefit from the cognitive support creatine offers, particularly during extended workdays, periods of stress, or frequent travel.
Risks and considerations
Creatine is considered safe at recommended dosages [1]. Some users experience weight gain related to water retention in muscle cells. Fears about kidney damage in healthy individuals are not supported by current evidence when recommended doses are followed.
Multivitamins: Nutritional Safety Net or Unnecessary Routine?
What are they for?
Multivitamins provide a range of essential nutrients that may be lacking in a standard diet, especially for individuals with inconsistent eating habits or increased needs, such as during pregnancy [2].
Where they fall short
Studies show limited evidence that multivitamins reduce the risk of chronic disease in healthy adults [2]. Over-supplementation of certain vitamins or minerals—such as vitamin A or iron—can also be harmful [3].
The smarter approach
Testing for actual deficiencies is more effective than guessing. Life First's comprehensive assessments include detailed pathology that helps identify gaps and inform targeted, relevant interventions.
Protein Powders: Convenient, but Are They Necessary?
Why they’re used
Protein supports muscle maintenance, immune function, and recovery. Powders offer convenience, especially for people with dietary restrictions or higher activity levels [4].
Downsides to consider
Protein powders are not tightly regulated, and product quality varies [5]. Whole food sources, such as lean meats, legumes, and dairy, provide similar benefits along with important co-nutrients like iron, zinc, and vitamin B12.
When they’re worth it
If your Life First results show elevated protein needs, for example, due to muscle loss, restricted diets, or specific training goals, your clinical team may recommend high-quality supplementation.
NMN and Longevity: Early Promise, Ongoing Research
What is NMN?
Nicotinamide mononucleotide (NMN) is a compound that helps boost NAD+ levels in the body. NAD+ is essential for energy production, DNA repair, and healthy ageing. As we age, NAD+ levels decline, leading to increased interest in NMN as a longevity supplement [6].
What the research says
While animal studies and early human trials suggest NMN may improve cardiovascular, metabolic, and cognitive function [6], more long-term clinical research is needed before widespread recommendations can be made.
Where Life First fits in
Our longevity-focused clients often explore advanced supplementation as part of a broader prevention strategy. Life First assessments provide the data and clinical guidance needed to evaluate these options safely and effectively.
Supplements Can Support, Not Substitute
Supplements can offer real benefits when used purposefully, but they are not a shortcut. The fundamentals, good nutrition, sleep, movement, stress management, and medical oversight, remain essential.
At Life First, we take a holistic, evidence-led approach to health. Every client undergoes a comprehensive assessment that includes advanced pathology, cardiovascular and cognitive screening, and consultations with an expert physician. This enables us to provide personalised, data-backed recommendations tailored to your specific health profile.
