Precision-dosed minerals, vitamins, gummies, herbal extracts, and functional shots - formulated in GMP-certified facilities and trusted by fitness professionals and nutritionists across the globe.
Your body depends on a precise, continuous supply of vitamins, minerals, and botanical compounds to maintain cellular energy, repair damaged tissue, regulate immunity, support bone strength, and sustain cognitive performance. Most adults carry measurable nutritional gaps they are unaware of - and those gaps compound silently over time.
ETERNIA was built specifically to close those gaps. Every formula begins with a systematic review of clinical literature. Every ingredient is selected in its most bioavailable form, at a dose that research confirms is therapeutically meaningful. Every batch is independently tested before a single bottle leaves the facility. This is not marketing language - this is simply how pharmaceutical-grade supplementation should work.
Magnesium Citrate, Calcium Citrate, Zinc, Selenium, and combination formulas for bone health, muscle function, and metabolic support
Collagen, Omega-3, Melatonin, Biotin, Multivitamins, and immune support formulas for adults and children
Fast-acting liquid formulas including Vitamin C Shot, B12 Shot, Collagen-C with Biotin, Sleep Shot, and Apple Cider Vinegar Shot
Standardised botanical formulas including Turmeric with Curcumin, Milk Thistle, Moringa, and Ginseng with Ginkgo Biloba
Vitamin D3, B-Complex, Vitamin C, CoQ-10, Resveratrol, NAD+ precursors, and gender-specific multivitamins
Most supplement brands use the cheapest available form of each nutrient and dose it below therapeutic thresholds to protect profit margins. We do neither. Every formulation decision at ETERNIA is governed by a single question: what does the clinical evidence say actually works?
That means Calcium Citrate over Carbonate for superior bioavailability without food. Zinc Citrate over Oxide for measurably higher absorption. Magnesium Citrate for gentler, more consistent uptake. Standardised curcuminoid extract with piperine for up to 2000% enhanced curcumin bioavailability. When there is a better form available, we use it - every single time, without exception.

Clinical nutritionists, registered dietitians, and sports medicine professionals recommend ETERNIA because they can verify what is inside every capsule and confirm that each dose reflects what the literature actually supports. That trust is earned through transparency, not advertising spend.
Our scientific advisory board includes leading physicians in diabetology, lifestyle medicine, and cardiovascular research who have reviewed our formulation standards and continue to inform our development pipeline.
Nicotinamide Adenine Dinucleotide is a vital coenzyme present in every cell, essential for energy production, DNA repair, and the activation of longevity genes. As we age, NAD levels decline, which can impair mitochondrial function and increase the risk of age-related diseases. Supplementing with NAD shows promise in reversing these effects, helping restore cellular energy, improve mitochondrial health, and support metabolic function. NAD supplementation has been shown to rejuvenate the mitochondria and reduce age-associated disorders.

A recent article in circulation now talks about the role of NAD+ in cardiovascular health. The benefits are of particular significance for patients suffering from cardiomyopathy including cardiomyopathy from general heart failure, preserved ejection fraction, or diabetes.

ETERNIA is a pharmaceutical-grade nutraceutical brand developed by QuadroPharma. Our supplements are formulated at clinically validated doses, manufactured in GMP-certified and FDA-registered facilities, and independently third-party tested for potency, purity, and safety before release.
Never. Every ingredient and its precise dose is clearly listed on our label. We do not use hidden proprietary blends because we believe you have the right to know exactly what you are putting into your body.
Yes. Every production batch is tested by an independent, ISO-accredited laboratory for ingredient identity, declared potency, microbiological safety, and heavy metal absence. No batch ships until it passes every test.
That depends on your specific health goals. If you are addressing bone health and muscle function, our Minerals range is a strong starting point. For daily nutritional support, our Vitamins and Supplements or Gummies range covers the most commonly deficient micronutrients.

Levels of NAD+ decline as we age and research now suggests that we can positively effect the aging process by boosting NAD+ levels. Supplementation of NAD+ / NAD+ precursors in human clinical trials have been found to increase life span, improve cardiovascular health, metabolic health, enhance cognitive function, and boost cellular energy production and thus have the potential to improve longevity, vitality, and healthy aging.
