We Like Getting to the Root of
Things, and the Science.
Naturally Derived
Bioactives.
PEA
Palmitoylethanolamide (PEA) is a fatty acid amide naturally made in the body and found in foods like egg yolks and peanuts.
It helps reduce inflammation and pain by activating PPAR-α receptors and calming nerve and immune cells, making it a safe, natural option for relieving chronic and neuropathic pain without the side effects of traditional painkillers.
Caraway
Caraway oil relieves digestive discomfort, primarily by relaxing smooth muscles in the stomach and intestines, which helps reduce cramping, bloating, and gas.
Caraway oil also exhibits antimicrobial and anti-inflammatory properties that may soothe inflamed digestive tissues and support gut health. It also has the ability to alleviate indigestion and improve symptoms related to functional dyspepsia, particularly when combined with peppermint oil.
Ivy
Ivy leaf supports respiratory health by acting as an expectorant that loosens and thins mucus, making it easier to clear from the airways.
It has bronchodilator and anti-inflammatory properties that help relax bronchial muscles and reduce airway irritation, easing coughs and improving airflow. Ivy’s natural compounds also have antimicrobial effects, which may aid the body in fighting infections. These combined actions make ivy leaf a versatile natural remedy for improving breathing and relieving cough-related discomfort.
Honey
Honey and propolis both support the immune system through their antimicrobial and anti-inflammatory properties.
Honey soothes the throat and acts as a natural antibacterial agent, helping to fight infections and reduce irritation. Propolis, a resin produced by bees, is rich in flavonoids and compounds that stimulate immune cells, enhance antibody production, and regulate inflammation. Propolis has demonstrated immunomodulatory effects by activating macrophages and T-lymphocytes, boosting both innate and adaptive immunity.
Thyme
Thyme supports respiratory health by acting as a natural expectorant, helping to loosen and clear mucus from the airways.
Its compounds, especially thymol, provide anti-inflammatory and antimicrobial effects that reduce airway irritation and fight infections. Additionally, thyme’s spasmolytic properties help calm coughing and relax respiratory muscles, aiding easier breathing and comfort during respiratory distress.
Ginger
Ginger helps relieve pain by blocking inflammation and calming pain pathways in the body.
Its key compounds, gingerols and shogaols, inhibit COX and LOX enzymes that produce inflammatory prostaglandins, while also acting on TRPV1 receptors to reduce pain signaling, making it effective for arthritis, muscle pain, and menstrual cramps.
Alpha-galactosidase
Alpha-galactosidase is an enzyme that aids digestion by breaking down complex sugars found in various carbohydrates. These sugars are otherwise fermented by gut bacteria, producing gas and discomfort.
By breaking down these carbohydrates earlier in digestion, alpha-galactosidase reduces gas production, bloating, and digestive discomfort. It supports better nutrient absorption and helps maintain a balanced digestive environment.
Caffeine
Caffeine helps relieve pain by blocking adenosine receptors in the brain and nervous system, which reduces pain signaling and inflammation.
It also constricts blood vessels, easing headache and migraine pain, and enhances the effects of common painkillers like acetaminophen and ibuprofen by boosting their analgesic potency.
Fennel
Fennel oil is known for strong digestive benefits, including reducing bloating, gas, and intestinal spasms.
Its active compound anethole relaxes smooth muscles in the gastrointestinal tract, easing cramps and promoting better digestion. Fennel oil also has anti-inflammatory and antimicrobial properties that help soothe intestinal irritation and support gut health.
Postbiotic
Postbiotic used in Colomend offers digestive and immune health benefits and works by adhering to the gut lining, promoting a healthy bacterial balance, strengthening the gut barrier, and supporting the integrity of tight junctions.
This helps improve digestion, reduce gastrointestinal discomfort, and enhance immune responses. Backed by over a century of research and more than 40 clinical studies.
Elderberry
Elderberry is rich in anthocyanins, powerful antioxidants that support immune health by reducing inflammation and protecting cells from oxidative stress.
These compounds also promote the growth of beneficial gut bacteria, which can enhance immune function through the gut-lung axis. Elderberry extracts have demonstrated antiviral activity and may help shorten the duration of respiratory illnesses by boosting the body's immune response naturally.
Alpinia
Alpinia galanga has been shown to significantly reduce fatigue and enhance mental alertness, focus, and energy without the side effects of caffeine.
Its bioactive compounds improve reaction time, accuracy, and attention, with effects lasting up to 5-7 hours after consumption. Alpinia also supports antioxidant defenses and neurotransmitter balance, helping reduce mental fatigue and daytime sleepiness.
Andrographis
Andrographis is used to reduce the duration and severity of symptoms associated with upper respiratory infections.
It works as an immune system stimulant by increasing antibody activity and enhancing macrophage function, which helps the body fight infections more effectively. Andrographis has demonstrated anti-inflammatory and antiviral properties, which contribute to symptom relief, including reducing sore throat, cough, and fever.
Reishi
Reishi mushrooms support immune health by boosting the activity and number of white blood cells, which are crucial for fighting infections and maintaining immune defense.
Compounds like beta-glucans in reishi stimulate immune cells such as macrophages and natural killer cells, enhancing the body's ability to detect and eliminate pathogens. Additionally, reishi exhibits anti-inflammatory effects that help regulate immune responses and may reduce chronic inflammation.
Peppermint
Peppermint oil relaxes smooth muscles throughout the gastrointestinal tract by blocking calcium channels, which helps reduce muscle spasms and cramping.
It also has anti-inflammatory and antimicrobial effects, contributing to improved digestion and reduced irritation. Peppermint oil can modulate nerve sensitivity in the gut, decreasing discomfort and pain sensations.
PEA
Calms inflammation and pain through PPAR-α receptor activation.
Caraway
Breaks down carbs to reduce gas and bloating.
Ivy
Loosens mucus and relaxes bronchial muscles for easier breathing.
Honey
Soothes throat and provides antimicrobial support.
Thyme
Clears mucus and calms airway irritation.
Ginger
Inhibits COX enzymes to reduce inflammation and pain.
Alpha-galactosidase
Breaks down carbs to reduce gas and bloating.
Caffeine
Blocks adenosine receptors to reduce pain and inflammation while constricting blood vessels for fast headache and migraine relief.
Fennel
Reduces bloating and calms intestinal irritation.
Postbiotic
Supports gut balance and strengthens the intestinal barrier.
Elderberry
Strengthens immune defense and shortens cold symptoms.
Alpinia
Inhibits COX enzymes to reduce inflammation and pain.
Andrographis
Boosts immune response and relieves cold symptoms.
Reishi
Supports immune balance and regulates inflammation.
Peppermint
Relaxes gut muscles and eases digestive discomfort.
Trelli selects bioactives from various natural sources
like botanicals, endogenous compounds, enzymes, or
postbiotics that have established human relevance.

Human clinical studies support
Our ingredient selection and claims are grounded in peer‑reviewed human studies measuring real outcomes.
Poor bioavailability is a common failure point for natural actives. We validate absorption with human PK data to confirm bio‑optimized formats are selected only when they meet target exposure thresholds.
Single Dose
Our goal is never to be creating a product that you take every day. Rather, we formulate for symptom relief meaning one dose is all it takes to feel better. Because feeling better should be a simple fix.
