Nervonic acid: a rare fatty acid in camelina oil
Camelina oil is primarily recognized for its omega-3 fatty acids and natural antioxidants. It also contains a lesser-known omega-9 fatty acid that is generating increasing scientific interest: nervonic acid. Here is what it is, its role in the body, and the amount found in camelina oil. What is nervonic acid? Nervonic acid is part of the very-long-chain fatty acid family, and some researchers consider it as important as the omega-3s DHA and EPA (Ren et al., 2026). It is a non-essential fatty acid: the body can produce it, unlike essential fatty acids such as omega-3 ALA, which must be obtained from the diet (Ren et al., 2026). But "non-essential" does not mean that food sources are without value. The body obtains nervonic acid by producing it, but also directly through the diet in a readily available form (Li et al., 2019). Its production in the human body requires several steps and does not always meet demand, for instance during brain development or myelin repair (Sargent et al., 1994; Liu et al., 2022). There is no official recommended intake for nervonic acid, since the body can produce it itself. Nevertheless, studies in humans show that dietary nervonic acid increases its levels in the body (Li et al., 2019; Sargent et al., 1994). A brief history Nervonic acid was first discovered in the brain and nervous tissue of humans and other mammals, hence its name (Liu et al., 2022; Ren et al., 2026). In 1926, Japanese researchers isolated it from shark oil (Ren et al., 2026). Its role in the nervous system Nerves function much like electrical wires, and myelin is the protective sheath that surrounds them and helps nerve signals travel quickly. Myelin is composed mainly of fat, and nervonic acid is one of its primary building blocks (Ren et al., 2026; Sargent et al., 1994). Nervonic acid is also present in breast milk, particularly in colostrum, the first milk produced after birth, which is important for the infant's brain development (Liu et al., 2022). Crossing the blood-brain barrier The blood-brain barrier is a highly selective layer of cells that lines the blood vessels of the brain. It protects the brain by blocking most substances in the blood, so much so that many nutrients and compounds never reach brain tissue. Ren et al. (2026) describe nervonic acid as being capable of crossing this barrier, which would allow it to support brain development and the repair of damaged nerve fibers. The reality is, however, more nuanced. In animal studies, dietary nervonic acid reached the brain primarily during the first few weeks after birth (Li et al., 2019). Researchers suggest that a specific transport pathway to the brain might exist, particularly in newborns, and this question is still under investigation (Li et al., 2019). What research says Lower levels of nervonic acid have been observed in people with demyelinating diseases—that is, diseases that damage the myelin sheath, such as multiple sclerosis and adrenoleukodystrophy (Li et al., 2019; Sargent et al., 1994). Currently, scientists are studying whether nervonic acid could help support myelin repair, but this research is still in its early stages (Liu et al., 2022). Animal studies have also looked into nervonic acid and brain function. In a feeding study, an oil rich in nervonic acid changed the fatty acid composition of the blood and brain in rodents and was associated with better learning abilities and cognitive functions (Liu et al., 2022). These results have not yet been confirmed in humans. Nervonic acid also seems to play a particularly important role in early life. Its levels in brain sphingolipids increase sharply after birth and peak around the age of 4 (Sargent et al., 1994). Breast milk from mothers of premature babies contains more nervonic acid, which could help compensate for their early arrival (Li et al., 2019). Is nervonic acid common in the diet? Not really. Natural oils rich in nervonic acid are relatively rare (Sargent et al., 1994), and it is absent from main vegetable oils such as soy, canola, and sunflower (Li et al., 2019; Liu et al., 2021). Camelina oil stands out: it contains not only nervonic acid, but also the fatty acids the body uses to produce it (Hajiazizi et al., 2023). It is also found in fish oils, breast milk, and seed oils of a few plants, such as borage and hemp (Li et al., 2019; Liu et al., 2022; Sargent et al., 1994). The richest plant sources are specialized seeds that are not part of the common diet, such as those of the honesty plant (Lunaria annua), the canary creeper (Tropaeolum speciosum), and the Malania oleifera tree (Liu et al., 2021). Nervonic acid in camelina oil Oils are almost entirely composed of fat, and fats are formed in large part by smaller elements called fatty acids. Published analyses report approximately 0.5 to 0.8% nervonic acid among the fatty acids in camelina oil (Hajiazizi et al., 2023; Xia et al., 2024). Our own analyses are consistent with the scientific literature: Signé Caméline cold-pressed camelina oil contains approximately 45 mg of nervonic acid per 2-teaspoon (10 mL) serving. Growing interest in nervonic acid Nervonic acid is attracting a great deal of attention for its potential in the nutraceutical and pharmaceutical fields (Li et al., 2019). Since its natural sources are limited and its extraction is costly, researchers are actively exploring new ways to produce it (Liu et al., 2022). This research includes the genetic modification of oilseed crops and microorganisms, such as yeast, to produce more nervonic acid (Li et al., 2019; Liu et al., 2022). Camelina itself has been used in this research: genetically modified lines have achieved 6 to 12% nervonic acid (Li et al., 2019). Signé Caméline oil comes from non-genetically modified camelina and naturally contains nervonic acid. At Signé Caméline, it is primarily our international buyers, particularly in Asia, who are interested in our oil for its natural nervonic acid content.

From grazing to first frosts: 7 tips to prepare your horse for winter
The leaves are changing colour, the days are getting shorter, and blankets are slowly coming out of storage. There's no doubt about it, fall has arrived! For our horses, this season brings several changes: less time on pasture, a thicker coat, and for some, the end of a busy competition season. Here are 7 tips to help your equine companion transition smoothly into winter! 1. Water: Don't Let the Cold Reduce Their Thirst! As temperatures drop, some horses tend to drink less, especially when the water becomes very cold. However, proper hydration remains essential, particularly for supporting healthy digestion. Good habits to adopt: Provide clean water, ideally at a moderate temperature and never frozen. Check water troughs at least twice a day. Keep an eye on water intake and manure. 💡 Did you know? A horse that isn't drinking enough may appear perfectly normal at first. That's one more reason to keep an eye on their habits! 2. From Pasture to Hay: A Transition That Makes All the Difference Fresh grass contains a lot of water, unlike hay, which is much drier. As pasture becomes scarce, your horse needs to drink more water to compensate. A sudden change in diet can also disrupt digestion. Our advice: Introduce hay gradually, choose good-quality forage, and make sure you have enough to last throughout the winter. 3. Less Fresh Grass, Less Omega-3? Did you know that fresh grass is a natural source of omega-3 fatty acids? When pasture is replaced by hay, your horse's intake of these beneficial fats may decrease. That's where camelina comes in! Grown in Quebec, this small plant produces an oil naturally rich in omega-3 fatty acids. Signé Caméline's camelina oil for horses contains approximately 35% omega-3 and can help support healthy skin, coat quality, and normal mobility. A great way to complement a balanced diet, especially when fresh grass becomes less available! 4. Competition Season Is Over: Time for Recovery! After months of training, competitions, or trail riding, fall often brings a slower pace. But even when activity levels decrease, proper nutrition remains important to help your horse stay in good condition! Have you heard of camelina protein? Made from camelina seeds after the oil has been extracted, our camelina protein contains 37% protein and all 10 essential amino acids. It can help maintain muscle condition and may be a valuable nutritional supplement after a busy season, depending on your horse's individual needs. 💡 A little tip: Gradually reduce training intensity and adjust your horse's feed ration to match their new activity level. 5. Winter Coat: Sometimes a Little Too Warm! As the days grow shorter, your horse naturally begins developing a thick winter coat. Perfect for handling cold weather, but sometimes a little too warm during those beautiful fall days! A horse that sweats heavily during exercise may take longer to dry. A few helpful tips: Adjust training sessions according to the temperature. Make sure your horse dries properly after exercise. Use a cooler blanket when needed. Consider partial clipping for highly active horses. Keep in mind: Not every horse needs a blanket. The important thing is to choose what works best for the weather conditions and your horse's individual needs. 6. Our Senior Companions Deserve a Little Extra Attention As colder weather approaches, some older horses may have more difficulty maintaining their weight and overall body condition. Now is the perfect time to give them a little extra care! Good habits to adopt: Regularly monitor their weight and overall condition. Check their dental health to ensure they can comfortably eat hay. Adjust their diet according to their nutritional needs. Consider an appropriate blanket to help them retain body heat and conserve energy during colder days. Thanks to its protein content, camelina protein may also be beneficial for some senior horses, particularly in helping maintain muscle condition. Because as our companions grow older, every little gesture of care matters! 7. Is Your Stable Ready for the First Frost? Before winter arrives, a little preparation can help you avoid unpleasant surprises! Your fall stable checklist: Check heated water troughs and have a backup plan in case of a power outage. Make sure you have enough hay for the winter. Inspect blankets, shelters, and fences. Secure areas that could become slippery. Schedule veterinary, dental, and farrier appointments. Keep your emergency veterinarian's contact information close at hand. Most importantly, take time to observe your horse every day. Any unusual change in behaviour, appetite, or daily habits deserves your attention. A Smooth Fall Transition with Signé Caméline Fall is a season of transition, but it's also a great opportunity to adjust your horse's daily routine. Proper hydration, balanced nutrition, and a little preparation can make all the difference as colder days approach. At Signé Caméline, we believe that our animals' well-being also starts with quality nutrition. That's why we make the most of camelina, a plant grown right here in Quebec, through our omega-3-rich oil and camelina protein. Because caring for our companions also means adapting alongside them as the seasons change. Written by Florence Rouillier and Dominique Derome
