Most people who buy a supplement focus on the active ingredient and pay little attention to the capsule it comes in. That is understandable. The capsule feels like packaging, not nutrition. But for a daily supplement like omega-3, taken every day indefinitely, the materials that make up the capsule are something every serving delivers alongside the active ingredient. For a few minutes of label reading, you can know exactly what that is. NutriGels, Performance Lab’s proprietary softgel capsule, are worth understanding specifically because they represent a genuine departure from what most vegan softgels use.
The short version is this: standard softgel capsules are made with gelatin, which is animal-derived. Vegan softgels typically substitute carrageenan, a seaweed-derived gelling agent that has generated legitimate research questions about its effects on intestinal health. NutriGels use neither. They are made from plant-derived gelling agents that avoid both of these concerns, and Performance Lab describes them as the first vegan softgel formulated specifically without carrageenan. That distinction is the reason they are worth a closer look.

What Standard Softgel Capsules Are Made From
A softgel capsule is a sealed, one-piece capsule that can contain liquid or semi-liquid fills, making it the ideal delivery format for oil-based supplements like omega-3. The classic softgel shell is made from gelatin, a protein derived from the collagen of animal hides, bones, and connective tissue. Gelatin produces an excellent softgel at low cost: it is flexible, forms a good seal, protects the fill from oxidation, and has a long track record in pharmaceutical and supplement manufacturing.
For products aimed at vegetarian or vegan consumers, gelatin is obviously problematic. Manufacturers looking for plant-based alternatives converged on carrageenan as the most practical gelling agent with properties comparable to gelatin. Carrageenan is extracted from red seaweed, it is technically plant-derived, and it produces a stable gel that functions reasonably well in softgel applications. The result is that carrageenan became the standard gelling agent in virtually all vegan softgel products on the market.
What Carrageenan Is and Why Some People Avoid It
Carrageenan has been a food additive for a long time, used as a thickener and stabilizer in everything from dairy alternatives to infant formula. Food-grade carrageenan is classified by the FDA as generally recognized as safe (GRAS). That classification has been contested in scientific literature, however. Research led by Dr. Joanne Tobacman at the University of Illinois documented that food-grade carrageenan activates inflammatory signaling in intestinal cells through a specific molecular pathway. The European Union applied precautionary restrictions on carrageenan in infant formula based on these concerns. The National Organic Program removed carrageenan from its approved list in 2016, though the decision was later reversed under industry pressure.
The debate is ongoing and the evidence does not support panic about occasional carrageenan exposure for most healthy adults. The calculus changes for people who have gut conditions that make them more sensitive to intestinal inflammatory signals, and it changes for anyone consuming a carrageenan-containing supplement every single day over the long term. A daily omega-3 capsule is precisely that kind of daily exposure, which is why the choice of gelling agent is more relevant here than it would be for an occasional supplement. The full detail on this issue is in the carrageenan in supplement capsules article, which covers the research and the regulatory picture in depth.
What NutriGels Are Made From
NutriGels use a combination of plant-derived gelling agents that achieve the structural and protective properties of a softgel capsule without gelatin or carrageenan. According to the Performance Lab Omega-3 supplement facts panel, the other ingredients in the NutriGels capsule shell are gellan gum, pectin, starch, and glycerin.
Gellan Gum
Gellan gum is a polysaccharide produced by bacterial fermentation of a carbohydrate substrate. It is used as a gelling and stabilizing agent in food and pharmaceutical applications, and it has a well-established safety profile. Unlike carrageenan, it has not been the subject of significant intestinal inflammation research concerns. It is used in small amounts in the capsule shell as part of the gelling system.
Pectin
Pectin is a naturally occurring polysaccharide found in the cell walls of fruits and vegetables. It is what gives fruit jams their gel-like consistency when cooked with sugar. As a supplement capsule ingredient, it contributes to the gel structure of the capsule shell and is entirely plant-derived with a safety profile that is both long-established and unconflicted. Pectin is classified as a soluble dietary fiber and has a favorable nutritional profile in its own right.
Starch and Glycerin
Modified starch serves as a structural component in the capsule formulation, contributing to film strength and flexibility. Glycerin (also called glycerol) is a humectant that keeps the capsule shell from becoming brittle. Both are widely used in food and supplement manufacturing. The starch in the NutriGels formulation is plant-derived, and vegetable-sourced glycerin is vegan. Together, these ingredients produce a capsule shell that functions comparably to gelatin softgels in protecting the oil fill, preventing leakage, and delivering the contents intact.
Why the Capsule Material Matters for Omega-3 Specifically
Omega-3 supplements are taken daily, indefinitely, which makes the capsule material more relevant than it would be for a supplement taken occasionally or for a short course. The other reason capsule quality matters specifically for omega-3 is oxidation protection. The polyunsaturated fatty acids in omega-3 oil are highly susceptible to oxidation when exposed to air, light, or heat. A good softgel capsule creates an oxygen barrier that protects the oil from degradation between manufacturing and consumption.
A capsule that fails to seal properly, degrades before it is swallowed, or allows oxygen permeation defeats part of the purpose of encapsulating the oil in the first place. Premium softgel technology, whether gelatin or a well-formulated plant-based alternative, maintains integrity through storage and transit. NutriGels are described by Performance Lab as designed for optimal absorption and gut comfort alongside their role in protecting the fill. The prebiotic fiber components (gellan gum and pectin are both fiber-like in their chemical character) support gut health rather than potentially working against it as carrageenan might.
How NutriGels Compare to Other Vegan Softgel Technologies
NutriGels are not the only plant-based softgel technology on the market, but they are one of the few that specifically identifies and avoids carrageenan. Most commercially available vegan softgels still use carrageenan as their primary gelling agent, because it is inexpensive and widely available. Some manufacturers use hydroxypropyl methylcellulose (HPMC), a plant-derived polymer used in standard hard capsules, in semi-softgel applications. NutriGels avoid HPMC as well, which Performance Lab notes in its product documentation.
The closest alternative approach is modified tapioca starch-based softgels, which some other manufacturers have adopted. These also avoid carrageenan and gelatin and produce a comparable capsule. The specific formulation used by Performance Lab differs in the combination of gelling agents but arrives at the same outcome: a vegan, carrageenan-free softgel that does not introduce the concerns associated with either conventional vegan softgel ingredients.
For a buyer evaluating supplement quality seriously, the capsule technology is part of what distinguishes a genuinely clean omega-3 supplement from one that merely looks the part on the label. The active ingredient matters most, but a product that applies the same rigor to every ingredient in the capsule, not just the headline nutrient, reflects a manufacturing philosophy that tends to carry through to other quality decisions.
Does the Capsule Material Affect Absorption?
This is a reasonable question and a fair one to address. Performance Lab claims that NutriGels support optimal absorption, partly because of the prebiotic-fiber character of some capsule components. The evidence for a direct absorption advantage from the capsule material itself is not extensively documented in the public literature. What is well-established is that omega-3 absorption is primarily driven by consumption with food, particularly food containing fat, which facilitates micellar incorporation in the small intestine.
The capsule material’s main role in absorption is getting the oil to the right place intact and undegraded. On that measure, a well-formulated NutriGel performs the same function as a well-formulated gelatin softgel: it protects the oil from premature degradation and releases it appropriately in the digestive system. The marginal absorption benefit from the capsule ingredients specifically is likely small compared to the impact of taking the supplement with a meal, but the absence of carrageenan removes a potential source of gut irritation that could theoretically interfere with absorption in sensitive individuals.
The Bottom Line
NutriGels are Performance Lab’s plant-based, carrageenan-free softgel capsules used in their Omega-3 product. They are made from gellan gum, pectin, starch, and glycerin, all plant-derived and free from the animal collagen of gelatin capsules and the research-questioned carrageenan used in most vegan softgels. For a daily supplement, the capsule is part of what you are consuming every day, and NutriGels represent a thoughtful answer to a question most supplement manufacturers have not bothered to ask.
If clean-label standards matter to you across the whole product, not just the headline ingredient, NutriGels are a meaningful differentiator. They are not the only reason to consider Performance Lab Omega-3, but they are one more piece of evidence that the product was designed with ingredient quality throughout rather than just at the active ingredient level.

Frequently Asked Questions
- What are NutriGels made from?
- NutriGels are made from a combination of plant-derived gelling agents: gellan gum, pectin, starch, and glycerin. They contain no gelatin, no carrageenan, and no HPMC. The formulation is entirely plant-based and vegan-certified, making it suitable for people who want to avoid animal-derived capsule ingredients without substituting carrageenan as the gelling agent.
- Are NutriGels vegan?
- Yes. NutriGels contain no gelatin or other animal-derived ingredients. Performance Lab describes them as the world’s first vegan softgel free from gelatin, HPMC, and carrageenan. All gelling agents in the capsule shell are plant-derived, and the full Performance Lab Omega-3 product, including the NutriGels capsule, is vegan certified.
- Why don’t most vegan softgels avoid carrageenan?
- Carrageenan is inexpensive, widely available, and technically plant-derived, which made it the default substitute for gelatin when manufacturers began producing vegan softgels. Developing carrageenan-free vegan softgel formulations requires more complex ingredient combinations and higher manufacturing costs. Most supplement manufacturers have not prioritized the change, which is why carrageenan remains standard in the category despite the research questions surrounding it.
- Does the NutriGels capsule affect how omega-3 is absorbed?
- The primary driver of omega-3 absorption is consuming the supplement with food, particularly food containing fat. The capsule’s main role is protecting the oil from oxidation until it is consumed and releasing it appropriately during digestion. Well-formulated vegan softgels including NutriGels perform this function comparably to gelatin softgels. Any marginal absorption benefit from the specific capsule ingredients is likely small relative to the effect of taking omega-3 with a meal.
