What Is NOURO?
NOURO is Tonum's daily cognitive-support supplement, built to nourish your body's most important organ: your brain. Its seven active ingredients, led by Alpha GPC and paraxanthine, are combined to support healthy cognitive function and overall brain health. It is made for adults who want research-grounded support for focus and long-term cognitive performance, without synthetic stimulants.
What's in NOURO
NOURO delivers seven actives in one daily serving of 4 capsules (30 servings per bottle):
| Ingredient | Amount per serving | What it's for |
|---|---|---|
| Niacin (as Nicotinamide) | 750 mg NE | A form of vitamin B3 (niacin) that supports normal metabolic and cellular function. |
| L-Taurine | 550 mg | Research describes taurine, a 'very essential' amino acid, for cellular energy and function. |
| Alpha GPC (GeniusPure®) | 450 mg | A choline source studied for its role in supporting cognitive function. |
| Berberine Phospholipid (Berbevis®, 28% berberine) | 400 mg | A phytosome form of berberine developed to address berberine's well-documented absorption problem, giving better absorption than standard berberine HCl. |
| Milk Thistle fruit extract (Siliphos®) | 400 mg | Studied as silymarin as an antioxidant liver therapy, part of the body's overall metabolic balance. |
| Paraxanthine (enfinity®) | 200 mg | A compound the body produces when it metabolizes caffeine, included as a source of alertness. |
| Alpha-Lipoic Acid | 175 mg | Supports cellular energy production and acts as an antioxidant; alpha-lipoic acid has also been examined in a meta-analysis of randomized trials. |
Other ingredients: Hydroxypropyl Methylcellulose (the capsule), Magnesium Stearate, Silicon Dioxide.
No synthetic stimulants and no unnecessary fillers.
How NOURO is different from MOTUS
NOURO and MOTUS share a metabolic backbone, both use Berbevis berberine, studied in a meta-analysis of 46 trials in type 2 diabetes, Siliphos milk thistle, taurine, alpha-lipoic acid and vitamin B3, because a healthy metabolism underpins a healthy brain. What makes NOURO a cognitive formula are two ingredients MOTUS does not contain:
- Alpha GPC (GeniusPure). A highly bioavailable source of choline, a nutrient the body uses in normal brain function. Alpha GPC has been studied specifically for cognitive support.
- Paraxanthine (enfinity). Paraxanthine is one of the compounds your body naturally produces when it breaks down caffeine. It is not caffeine itself. Tonum includes it as a source of daytime alertness, which is why NOURO is designed to be taken in the morning.
How NOURO supports your brain
The framing Tonum uses for NOURO is structure-function, meaning it describes how the formula supports normal function, not treatment of any condition:
- Supports healthy cognitive function and overall brain health.
- Supports long-term cognitive performance later in life.
- Promotes resilience and performance in high-impact sports and lifestyles.
NOURO is a supplement, not a medication. It is not intended to diagnose, treat, cure or prevent any disease or condition.

Who makes NOURO?
NOURO is made by Tonum, the consumer brand of Prostasis, LLC, a US company founded by Mark Brosso and led by CEO Lance Converse, both with decades in pharmaceutical data and clinical research. Tonum was founded after Brosso's father developed early-onset Alzheimer's, a personal experience that shaped the company's mission to build natural products held to pharmaceutical-grade research standards. That mission is why brain health became a focus for the brand.
Who is NOURO for?
NOURO is designed for adults who want to support everyday focus, mental clarity and long-term cognitive performance, and for active people in demanding sports or lifestyles who want to support resilience and performance. NOURO is not a medication and is not a substitute for one; if you take prescription medication or have a medical condition, talk to your doctor before adding any supplement.
How to take NOURO
Take 4 capsules every morning. Because NOURO includes paraxanthine as a source of alertness, morning dosing helps keep it from interfering with sleep. Take with or without food, whatever fits your routine.
Frequently asked questions
What is NOURO?
NOURO is Tonum's daily cognitive-support supplement. Its seven active ingredients, including Alpha GPC and paraxanthine, are combined to support healthy cognitive function and overall brain health. You take 4 capsules each morning.
What is in NOURO?
Seven actives per 4-capsule serving: niacin (as nicotinamide), L-taurine, Alpha GPC (GeniusPure), Berbevis berberine phospholipid, Siliphos milk thistle, paraxanthine (enfinity) and alpha-lipoic acid, plus a plant-based capsule and standard manufacturing aids.
Does NOURO contain caffeine?
NOURO contains paraxanthine, which is a compound your body naturally produces when it metabolizes caffeine. Paraxanthine is not the same as caffeine. Tonum includes it as a source of daytime alertness, which is why NOURO is taken in the morning.
What does Alpha GPC do?
Alpha GPC is a highly bioavailable source of choline, a nutrient the body uses in normal brain function. It has been studied for its role in supporting cognitive function. In NOURO it is included at 450 mg per serving.
Can I take NOURO with MOTUS?
NOURO and MOTUS are designed as separate daily formulas and share several of the same ingredients, so they are not simply meant to be stacked at full dose. If you are considering taking both, talk to Tonum support or your doctor about what is right for you.
How long until NOURO works?
NOURO is a daily supplement and works best with consistent use over time; the brain-support benefits Tonum describes are about long-term cognitive performance, not an instant effect. Individual experiences vary.
Is NOURO trustworthy?
NOURO is manufactured in the USA in an NSF-certified, cGMP-compliant facility and is third-party tested, with no synthetic stimulants. More than 10,000 customers have used Tonum products.
