At the intersection of self-optimisation and science, biohacking has exploded into mainstream wellness, with everyone from corporate executives to elite athletes seeking tools to boost energy, focus, and longevity. For many, supplements have long been the go-to. But what happens when we challenge the pill-first mentality? You may have heard whispers in the wellness industry regarding non-invasive, drug-free infrared light therapy devices, which are gradually gaining popularity. But can something as simple as light stand up against capsules and powders? And more importantly, is it the safe option?
Let's explore the science behind infrared light therapy and how it compares to supplement-based biohacking methods in terms of both safety and efficacy.
Biohacking refers to using science, technology, and lifestyle interventions to optimise health and performance. While the trend spans everything from sleep tracking to gene editing, it's the accessible tools—like dietary supplements and red light devices—that are most popular among everyday biohackers.
However, accessibility doesn't always equal safety. According to a 2015 review published in The New England Journal of Medicine, approximately 23,000 emergency hospital visits in the US each year are linked to dietary supplements—ranging from allergic reactions to liver toxicity. Though New Zealand-specific data is limited, the global implications are clear: not all supplements are as safe as they appear.
In contrast, infrared light therapy devices don't carry the same systemic risks. You're not ingesting anything, nor are you altering your biochemistry in unpredictable ways. The light interacts with your cells, particularly the mitochondria, triggering a cascade of regenerative effects.
Infrared light therapy penetrates the skin and improves cellular function by using wavelengths ranging from 600nm to 1,000nm. The process is based on mitochondrial activation, which occurs when your cells absorb light and produce more adenosine triphosphate (ATP), your body's energy currency. Increased ATP production can promote faster healing, reduced inflammation, improved circulation, and enhanced cognitive clarity.
Crucially, infrared light therapy devices are non-invasive and pose minimal risk when used as directed. Rojo Light Therapy NZ's panels, for instance, comply with safety standards and offer adjustable settings to suit different skin types and health goals.
Supplements, when used properly, can fill genuine nutritional gaps. They can support hormone production, muscle recovery, immunity, and even cognitive function. However, bioavailability varies widely. Some compoundslike curcumin or resveratrol,are notoriously poorly absorbed unless paired with specific agents.
More concerning is the lack of regulation. Unlike pharmaceuticals, many over-the-counter supplements are not required to undergo rigorous testing. Additionally, stacking supplements, taking multiple products at once, can increase the risk of nutrient imbalances or adverse interactions. There's also the problem of 'megadosing,' where people consume far above recommended limits in pursuit of faster results, sometimes leading to toxicity.
When it comes to invasiveness, infrared light therapy is non-invasive, simply delivering targeted wavelengths to your skin and underlying tissues. In contrast, supplements must be ingested and processed by your digestive system, making them a systemic intervention.
Infrared light therapy devices are subject to safety standards for medical or wellness devices, offering controlled, targeted exposure. Supplements, especially in New Zealand, face limited regulatory scrutiny. That leaves room for contamination, ingredient inconsistencies, and exaggerated claims.
In terms of side effects, infrared light therapy often results in very little discomfort, such as a mild warming sensation on the skin. On the other hand, supplements can cause a range of adverse effects—from allergic reactions and gastrointestinal issues to more severe consequences like liver damage, particularly with fat-soluble vitamins or herbal extracts.
Overuse is also a major consideration. With infrared therapy, overexposure is rare and usually harmless when the manufacturer's guidelines are followed. Supplement misuse, however, is far more common, especially with self-prescribed regimens or influencer-endorsed stacks that lack clinical backing.
Bioavailability further distinguishes the two. Infrared treatment works directly on a cellular level, promoting natural energy production without relying on digestion or metabolic conversion. Supplements often suffer from poor absorption, meaning a significant portion may go unused or even cause gut irritation.
Rather than framing infrared light therapy and supplements as opposing tools, it's more productive to view them as complementary. However, if you're new to biohacking and concerned about safety, red and near-infrared light devices are a safer starting point.
They deliver tangible benefits without the metabolic guesswork, ingredient sourcing, or risk of overdose. As long as you use a high-quality device, such as those from Rojo Light Therapy NZ, you're investing in a proven modality grounded in real science.
Rojo Light Therapy NZ offers medical-grade, evidence-based red and near-infrared light devices designed for home use. Whether you're chasing recovery, skin rejuvenation, or sharper mental clarity, our panels help you optimise—safely and effectively.
