At the 2026 Brain Health & Sleep-Emotion Application Innovation Forum, Natural Field presented its latest work in sleep health, with a focus on a question that is becoming increasingly relevant to supplement formulators: how can individual functional ingredients be combined with delivery technology to create more targeted sleep health products?
The presentation introduced the development thinking behind the NF TriSolve® Sleep Health Solution, from Ashwagandha research and co-loaded liposomal technology to multi-ingredient formulation and scientific evaluation.
For Natural Field, however, the research is not only about one finished solution. It also reflects the growing opportunity for individual sleep and brain health ingredients in modern supplement formulations.
Sleep products have traditionally focused on one primary goal: helping consumers fall asleep.
That market is changing. Formulators are increasingly looking at sleep quality more broadly, including sleep continuity, relaxation, stress, circadian rhythm, and the relationship between sleep and daytime wellbeing.
This has made multi-ingredient formulations more common. Instead of asking which single ingredient can support sleep, formulators are considering how several ingredients can complement one another within the same product.
The NF TriSolve® Sleep Health Solution is one example of this approach.
Ashwagandha is at the center of Natural Field's sleep health research.
As a botanical adaptogen, Ashwagandha has attracted attention in areas such as stress response, sleep quality, emotional balance, and neural regulation. This makes it particularly interesting for formulations that connect stress management with sleep support.
Natural Field offers standardized Ashwagandha extract powders, including 5% withanolides, as well as water-soluble and debittered Ashwagandha options for different formulation requirements.
But Ashwagandha is only one part of the formulation picture.
Melatonin remains an important ingredient for products built around circadian rhythm and sleep timing. In a multi-ingredient formula, it can be combined with ingredients that address other aspects of the sleep experience rather than being used as the sole active.
GABA is commonly used in relaxation and sleep-oriented formulations, while L-theanine is often selected for products positioned around relaxation and stress management. Magnesium glycinate provides another option for formulators developing relaxation and sleep support products, particularly when a well-established magnesium form is preferred.
Other ingredients can be used to broaden the formulation strategy. 5-HTP is commonly considered in sleep- and mood-related products, while vitamin B6 can be incorporated into nutritional formulations involving neurotransmitter-related pathways.
Natural Field's ingredient portfolio includes these key ingredients, giving manufacturers the option to source individual raw materials for their own formulations rather than relying on a single pre-designed formula. The company's current product portfolio lists Ashwagandha extract, GABA, 5-HTP, melatonin, magnesium glycinate, and theanine among its brain and sleep-related ingredients.
Ingredient selection is only part of the formulation process.
Some functional ingredients can be challenging to formulate because of limitations related to solubility, stability, compatibility, or absorption. This is one reason delivery systems have become an important area of nutraceutical research.
During the forum, Natural Field presented its work on Ashwagandha-based co-loaded liposomal technology, including the exploration of co-loading Ashwagandha-related actives with melatonin.
The concept goes beyond simply combining ingredients in a powder blend. By incorporating functional actives into a liposomal delivery system, the research explores whether delivery technology can improve the way selected ingredients are handled within a formulation.
This work forms part of Natural Field's broader NF TriSolve® technology platform, which combines functional ingredients, delivery technology, and formulation development.
The broader takeaway from the forum is fairly straightforward: sleep health innovation does not always require a completely new ingredient.
There is still considerable room to innovate through ingredient selection, combinations, delivery systems, and formulation design.
For manufacturers developing sleep support products, this can mean combining familiar ingredients in new ways—for example, pairing Ashwagandha with melatonin, GABA, L-theanine, or magnesium glycinate depending on the intended product concept.
For brands looking beyond individual ingredients, delivery technologies such as co-loaded liposomes may offer another route for developing differentiated formulations.
Natural Field works across both sides of this development process: supplying functional ingredient powders for manufacturers while continuing to explore more advanced delivery and formulation solutions through platforms such as NF TriSolve®.
The research presented at the forum reflects a simple progression:
Start with the right ingredients. Understand how they can work together. Then use formulation and delivery technology to explore what is possible.
For the sleep health market, Ashwagandha, melatonin, GABA, L-theanine, magnesium glycinate, and 5-HTP each provide different formulation opportunities. The challenge—and the opportunity for manufacturers—is determining how to combine them into products that fit a specific consumer need and market position.
That is where Natural Field's role as both a functional ingredient supplier and formulation technology developer comes into play.
From individual raw materials to more advanced delivery systems, the goal is not simply to add more ingredients to a formula. It is to help manufacturers make better use of the ingredients they choose.
