At NOA, quality is never accidental. Every formula is the result of years of research, clinical experience, and careful scientific decision-making.

To take you behind the scenes of how NOA supplements were created, we spoke with Dr. Nikola Martić, a medical doctor and Associate Professor at the Faculty of Medicine, with years of experience in both clinical practice and academic research.

Dr. Martić holds a PhD in the application of plant extracts in living systems, with a strong scientific focus on the bioactive properties of natural compounds and their mechanisms of action in modern therapy. His work bridges academic precision with real-world health outcomes, exploring how carefully selected natural ingredients can support physiological balance and long-term wellbeing.

As one of the key experts involved in shaping NOA formulations, Dr. Martić played an essential role in ingredient selection, dosing strategy, safety protocols, and real-world testing, ensuring that NOA supplements are driven by science, safety, and real physiological needs, rather than trends or marketing claims.

In the following conversation, he shares the thinking behind NOA’s formulation philosophy, explains why certain ingredients were chosen, and others deliberately excluded, and offers a deeper insight into what truly defines high-quality supplementation today.

How did the development process of the NOA formulation begin, and what was the main focus?

NOA was envisioned as something truly new in the supplement market. That is why its story began years before the products themselves were launched. The original idea was born in the mind of a Master of Pharmacy at the very beginning of the COVID-19 pandemic and evolved in many directions before finally coming to life.

From the very start, the core focus was clear: to create supplements that combine high efficacy with uncompromising safety.

Efficacy was addressed through carefully selected, broad-spectrum formulations designed to cover most known physiological causes of reduced metabolic function in specific organs or organ systems. Nutritional needs differ significantly depending on geography, lifestyle, and diet, which means that micronutrient and macronutrient deficiencies are rarely uniform.

For example, NOA Hair is formulated to address a wide range of potential nutritional gaps affecting skin and hair health, making it a truly universal supplement for their nourishment and support.

Safety, on the other hand, was ensured through several layers of testing. Development began with clinical experience, followed by strict alignment with the latest global scientific recommendations regarding ingredient selection and dosing. This was complemented by rigorous laboratory safety analyses to guarantee that the product would not cause even minimal discomfort.

The final phase of testing involved monitored use by study participants who consumed only NOA products, sharing their observations under strict medical supervision.

NOA includes ingredients rarely seen in commercial supplements, such as iodine. Why was this important?

Iodine is an essential micronutrient required for the synthesis of thyroid hormones, which regulate the metabolism of every cell in the body — including skin cells and hair follicles — as well as the metabolic activity of all other organs.

Globally, it is estimated that nearly 2 billion people (almost 30% of the world’s population) remain at risk of insufficient iodine intake.

Our goal was to provide minimal but optimal iodine doses, supplying approximately 25–50% of the recommended daily intake across NOA products. This supports normal thyroid function while remaining safe even for individuals with thyroid disorders.

For example, iodine deficiency can lead to reduced thyroid activity, often reflected in pale, cold skin with low metabolic activity — conditions that cannot support healthy, resilient hair. Similarly, overall energy levels and metabolic efficiency depend heavily on adequate iodine intake. This is why iodine was included in both NOA Hair and NOA Slim, always with safety as the priority.

MSM is often mentioned, but rarely understood. Why is it important in NOA formulations?

MSM (Methylsulfonylmethane) is a valuable supplement, particularly for skin, hair, nails, and joint health. Its importance lies in its sulfur content — an essential building block of connective tissue.

Sulfur is required to form the chemical bonds within keratin, the primary structural protein of hair, skin, and nails. Without sulfur, even sufficient collagen and other nutrients cannot be properly integrated into these tissues.

MSM supports stronger hair follicles, healthier nail structure, and improved skin firmness, contributing to resilience and a more youthful appearance.

How were ingredients combined to work synergistically rather than individually?

This is one of the most important aspects of NOA formulations.

The combinations were developed through collaboration between multiple healthcare disciplines — practicing pharmacists, physicians, and food supplement technologists. Each formulation was carefully designed so that ingredients support and enhance one another, ensuring that the combined effect exceeds the sum of individual components.

This was achieved through precise dosing of high-quality ingredients, ensuring maximum benefit without unwanted side effects, while supporting skin, hair, and overall metabolic health when used together.

Which safety and efficacy parameters were non-negotiable during development?

Safety has always been the highest priority.

NOA products undergo strict laboratory testing for heavy metals, with every production batch monitored in real time. No product leaves production unless it meets the highest safety standards.

Additionally, rigorous microbiological testing ensures product purity. Manufacturing takes place in facilities that meet the highest food production standards.

Efficacy is monitored through continuous medical observation and real-world feedback from users worldwide. These experiences are carefully documented and analyzed — and so far, the results have been extremely positive.

How were ingredients selected, and which ones were deliberately excluded?

Ingredient selection was based on four key criteria:

• Proven scientific efficacy

• Safety

• Regulatory compliance with global standards

• Clear functional purpose within the formulation

NOA formulas combine traditional ingredients with centuries of documented use and modern compounds supported by current scientific research. This synergy delivers unique and effective results.

We deliberately excluded ingredients lacking scientific evidence, those associated with allergenic potential, ingredients under toxicological review, and substances raising ecological or ethical concerns. All ingredients are sourced responsibly, from renewable origins, and are free from microplastics.

What effects might users notice first with NOA Hair and NOA Slim?

Results vary individually, but with NOA Hair, the earliest visible effects often appear in the skin — improved glow and elasticity — followed by stronger hair roots and new hair growth over time.

With NOA Slim, effects may be noticed within days, including reduced cravings between meals, increased energy, and a lighter feeling in the digestive system. Many users describe improved energy utilization and overall metabolic comfort.

Who would you especially recommend NOA for?

NOA products are particularly suitable for individuals with demanding lifestyles who may struggle to meet their nutritional needs through diet alone.

• NOA Hair supports hair strength, elasticity, and natural pigmentation

• NOA Slim is designed to support digestive health, blood sugar balance, and weight management

How do you see the future of supplementation?

The future of supplementation lies in scientific personalisation, advanced biotechnology, and full transparency.

The era of “one supplement fits all” is ending. The future belongs to targeted, organ-specific supplementation, focused on precision and prevention rather than generic formulas.

What has marketing taught people incorrectly about supplements, and what does science say?

Marketing often promotes exaggerated promises, while science emphasizes realistic expectations and targeted use.

Three key truths:

1. Supplements complement nutrition, they do not replace it. Balanced diet, quality sleep, and physical activity remain the foundation of health.

2. Supplements are not magic pills. They support specific functions but do not cure all health conditions.

3. Evidence matters more than slogans. Always choose supplements backed by scientific research.
