Ensuring Stability in Oil-Based Nutraceutical Formats
Natural antioxidant solutions for softgels, liquid capsules, and functional oils

Market Overview & Industry Challenges
The global nutraceutical market is experiencing sustained growth, driven by rising consumer awareness of preventive health and wellness. Delivery formats such as softgels, liquid capsules, and functional oils are increasingly preferred due to their superior bioavailability and ease of consumption.
However, these oil-based systems present a major formulation challenge: lipid oxidation. Oils rich in polyunsaturated fatty acids (PUFAs), such as omega-3 and botanical extracts, are particularly vulnerable to oxidative degradation. This process leads to the formation of peroxides and secondary oxidation compounds, resulting in off-flavors, reduced efficacy, and loss of nutritional value¹.
In addition, the growing demand for clean label nutraceuticals is pushing manufacturers to replace synthetic antioxidants with natural alternatives—without compromising product stability. As a result, ensuring oxidative stability and extended shelf life in oil-based supplements has become a key priority across the industry.
Nutrabiol®: Natural Protection for Oil-Based Formulations
Nutrabiol® is a range of natural antioxidants based on mixed tocopherols (natural Vitamin E), specifically developed to protect lipid-based nutraceutical systems from oxidative degradation.
Sourced from vegetable oils, Nutrabiol® offers a highly efficient antioxidant solution that integrates seamlessly into oil-based formulations, including:
- Softgel capsules
- Liquid food supplements
- Functional and fortified oils
- Omega-3 and specialty lipid blends
Its antioxidant activity helps preserve the chemical integrity, sensory profile, and nutritional value of oils throughout the product lifecycle, from production to final consumption.
Nutrabiol®
At BTSA, we offer Nutrabiol®, a natural tocopherol-based solution designed to effectively prevent lipid oxidation and enhance the shelf life of oil-based nutraceutical products.
Tocopherols are well-known chain-breaking antioxidants that act by donating hydrogen atoms to lipid radicals, thereby interrupting the propagation phase of oxidation². This mechanism is especially effective in protecting polyunsaturated fatty acids, which are highly sensitive to oxidative stress.
Scientific studies have demonstrated that the addition of natural tocopherols significantly delays the onset of oxidation (induction period) and reduces the formation of degradation compounds in oil systems³. This translates into measurable improvements in product stability, shelf life, and overall quality.
In practical applications, Nutrabiol® provides key advantages for nutraceutical manufacturers:
- Protection of sensitive actives such as omega-3, carotenoids, and fat-soluble vitamins.
- Stabilization of organoleptic properties, preventing rancidity and off-notes.
- Preservation of nutritional value, ensuring label claim compliance over time.
- Compatibility with encapsulation technologies, including softgels and liquid delivery formats.
- Support for clean label positioning, replacing synthetic antioxidants like BHA or BHT.
By incorporating Nutrabiol®, manufacturers can ensure that their oil-based formulations remain stable, effective, and consumer-friendly throughout their intended shelf life.
