Brain Support
Best-in-class: Brain Factors
Thorne Brain Factors. One capsule is nicotinamide riboside hydrogen malate 415 mg, CognatiQ whole coffee fruit extract 100 mg and betaine anhydrous 85 mg -- an NAD+ precursor formula, not a choline-and-botanical nootropic. There is no citicoline, phosphatidylserine, bacopa, ginkgo or huperzine in it.

Judge it as an NAD+ product, because that is what it is. The interactions that belong to choline donors, ginkgo and vinpocetine do not apply here — but the underdosing question does, and it is the sharpest thing on this card: 415 mg of a nicotinamide riboside malate salt is not the 1,000 mg of nicotinamide riboside chloride the human trials used, and 85 mg of betaine is a small fraction of the gram doses behind betaine's own evidence.
How Brain Support actually works
Not the multi-mechanism blend the category name suggests. Thorne's Brain Factors runs essentially one: nicotinamide riboside is an NAD+ precursor, salvaged to NMN and then to NAD+, the cofactor every mitochondrial dehydrogenase depends on. Betaine is there as a methyl donor, which is relevant because NAD+ precursors are cleared by methylation. The coffee whole fruit extract is the outlier, included on a reported rise in circulating BDNF. There is no choline source, no ginkgo or vinpocetine, and no adaptogen in it.

Graded by what exists behind each claim.
✅ Clinically validated
- Nicotinamide riboside reliably raises blood NAD+ in randomized trials — that is the firm endpoint. Cognitive outcomes from NAD+ precursors are much thinner than the biochemistry behind them.
- Betaine's established endpoint is homocysteine lowering, and that was shown at gram doses rather than the 85 mg in this capsule.
- Blend-level trials of the finished product are fewer than the single-ingredient studies.
📊 Correlative data
- Cognitive decline tracks with age, stress and poor metabolic/vascular health.
🧪 Theoretical / extrapolated benefits
- Whole coffee fruit extract is in the formula for a reported rise in serum BDNF, from small studies. Plausible mechanism, thin human read-out.

What Brain Support actually does
Before any mechanism, the label, because on this product the label and the category description are not describing the same thing. Per capsule, as filed with the NIH Dietary Supplement Label Database: nicotinamide riboside hydrogen malate 415 mg; a whole coffee fruit extract (CognatiQ) 100 mg; and betaine anhydrous, which is trimethylglycine, 85 mg NIH DSLD 313910. That is the entire active formula. There is no citicoline in it, no phosphatidylserine, no bacopa, no ginkgo, no alpha-GPC and no huperzine.
So this is not a nootropic blend. It is an NAD precursor, a neurotrophin claim and a methyl donor. Those three do genuinely different things and none of them is cholinergic.
Nicotinamide riboside is a salvage-pathway entry point. It is phosphorylated by nicotinamide riboside kinase 1 or 2 to nicotinamide mononucleotide, then adenylylated by NMN adenylyltransferase to NAD+. That route bypasses nicotinamide phosphoribosyltransferase, the rate-limiting enzyme of the classical salvage pathway, which is the whole pharmacological argument for the molecule. The competing fate is cleavage: purine nucleoside phosphorylase can strip the ribose and leave plain nicotinamide before the compound ever reaches a distant tissue, which is why oral NR raising blood NAD+ and oral NR raising brain NAD+ are two separate empirical questions Martens 2018 Brakedal 2022.
Betaine is one enzyme. Betaine-homocysteine methyltransferase, expressed mainly in liver and kidney, transfers a methyl group from betaine to homocysteine to regenerate methionine. That is a folate-independent branch of the same junction phosphatidylethanolamine N-methyltransferase draws on when the liver builds choline de novo, which is why betaine and choline are two ends of one methyl budget Obeid 2023.
The coffee fruit extract is a neurotrophin claim, and it is worth being precise about what was measured. The evidence is a rise in plasma brain-derived neurotrophic factor after a single oral dose Reyes-Izquierdo 2013. Circulating BDNF in humans is overwhelmingly stored in platelets and released on clotting; plasma BDNF is therefore a peripheral measurement whose relationship to BDNF in the brain is assumed rather than demonstrated. That is the single most important caveat on this ingredient and it is never printed.
Cell, rodent, human — and where it stops
Nicotinamide riboside in healthy people. Chronic supplementation was well tolerated and elevated NAD+ in healthy middle-aged and older adults Martens 2018. That is a biomarker result: the molecule does what its biochemistry says.
Nicotinamide riboside in a brain, at a dose four times this capsule. The NADPARK trial randomized 30 newly diagnosed, treatment-naive Parkinson's patients to 1,000 mg/day of NR or placebo for 30 days and found increased cerebral NAD levels, mild clinical improvement and decreased inflammatory cytokines Brakedal 2022. A follow-up safety trial took the dose higher still in the same population Berven 2023. Cerebral NAD has therefore been shown to move in humans — in 30 people with a neurodegenerative diagnosis, at 1,000 mg a day.
Whole coffee fruit extract. A single 100 mg dose in fasted healthy subjects raised plasma BDNF by 143%; the comparison arms rose by roughly 31%; n = 10 Reyes-Izquierdo 2013. Ten people, one dose, one peripheral biomarker, no cognitive endpoint.
Betaine. Six grams a day lowers plasma homocysteine in healthy men and women Steenge 2003. Six grams. This capsule contains 85 mg NIH DSLD 313910, which is 1.4% of that dose.
The obstacle, arithmetically. Three ingredients; three human doses of 1,000 mg, 100 mg and 6,000 mg; and a capsule delivering a fraction of a salt for the first, exactly the studied amount of the second — whose study had ten people and no cognitive outcome — and a hundredth of the third. Every one of the human trials behind this product measured a biomarker rather than cognition, and two of them were in Parkinson's disease. Nothing here has been tested against a memory or attention endpoint in a healthy adult.
Brain Support — which form, and does it matter
The salt is the first thing to notice and the label does not resolve it. The declared ingredient is nicotinamide riboside hydrogen malate at 415 mg NIH DSLD 313910. The form used in the human trials is nicotinamide riboside chloride Martens 2018 Brakedal 2022. A counter-ion carries mass: the quantity of nicotinamide riboside inside 415 mg of a malate salt is necessarily less than 415 mg, and the label does not state the difference. Anyone comparing this to the 1,000 mg used in NADPARK is comparing a salt weight to a different salt weight.
NR is not niacin and not nicotinamide, and the difference is the point of paying for it. All three raise NAD+; niacin does it with a flush through GPR109A, nicotinamide does it through the rate-limited classical salvage step, and NR enters past that step. The absence of a flush on this product is a statement about which molecule you took, not evidence that it was absorbed — a distinction people routinely get backwards.
Betaine anhydrous is not betaine hydrochloride. The anhydrous form here NIH DSLD 313910 is the methyl donor studied for homocysteine Steenge 2003. Betaine HCl is sold as a stomach-acid aid and is a different purchase entirely. At 85 mg neither does the homocysteine job.
The coffee fruit extract is proprietary and the dose matches. One hundred milligrams is the amount used in the published acute study Reyes-Izquierdo 2013 NIH DSLD 313910, which is unusual on this shelf and worth crediting. What it does not fix is that the study was ten people and a plasma marker. The label also does not declare a caffeine content for a coffee-derived extract, which is worth checking if you are sensitive.
What would have to be true, and how you would know it was not
1. Whole-blood NAD+ is measurable, and this is the honest engagement test. Predict it rises, because chronic NR raised NAD+ in healthy middle-aged and older adults Martens 2018. Then predict the uncomfortable half: that nothing you can score cognitively moves with it, because the trials that raised NAD+ measured NAD+, and the trial that showed cerebral NAD rising did so at 1,000 mg a day in people with Parkinson's disease Brakedal 2022.
2. Homocysteine, before and at 12 weeks, as the prediction that cuts against the product. Predict no change. Eighty-five milligrams of betaine is 1.4% of the 6 g that lowered homocysteine in healthy adults Steenge 2003 NIH DSLD 313910. If your homocysteine does fall, look at the folate and B12 you are also taking, because the betaine in this capsule is not a plausible cause.
3. TMAO, and here is why it belongs on this page. Betaine and choline sit on the same microbial pathway to trimethylamine, and plasma TMAO tracked major adverse cardiovascular events at a hazard ratio of 2.54 in 4,007 patients Tang 2013. At 85 mg the predicted effect is none — but if you are taking this alongside a choline product, a carnitine product or a high-dose betaine for training, the load is additive and one fasting TMAO answers the question.
What will fool you: expecting the warnings that are printed for this category to apply. The ginkgo bleeding interaction and the huperzine cholinergic interaction are the standard cautions for nootropic blends and neither ingredient is in this product NIH DSLD 313910. Reading the category instead of the label misleads in both directions.
What nobody has tested yet
Nobody has measured cerebral NAD after nicotinamide riboside in a healthy adult. It has been measured, by magnetic resonance spectroscopy, in newly diagnosed Parkinson's patients at 1,000 mg/day Brakedal 2022. Whether a well 40-year-old on a lower dose of a different salt moves cerebral NAD at all is unknown, and it is the premise of the product.
The coffee fruit result has never been extended. A 143% rise in plasma BDNF in ten fasted people after a single dose Reyes-Izquierdo 2013 is a starting point, not a finding. Nobody has repeated it in a larger sample, measured it after chronic dosing, controlled for platelet activation during venipuncture, or measured anything downstream of BDNF such as a learning task.
Nobody has published the nicotinamide riboside content of the hydrogen malate salt in an independent assay. Until somebody does, no buyer can convert 415 mg NIH DSLD 313910 into a fraction of the 1,000 mg used in the clinical work Brakedal 2022.
And the three have never been given together in a trial. There is no study of this combination at these doses on any endpoint, which means the product's own claim — that these three are complementary — is a hypothesis with a price.
Brain Support — its own safety story, not its category's
The tolerability data on the main ingredient is unusually good. Chronic nicotinamide riboside was well tolerated in healthy middle-aged and older adults Martens 2018, and a dedicated randomized double-blind safety trial has now tested high doses in Parkinson's disease Berven 2023. Very little on this shelf has a trial whose primary purpose was safety.
The honest caveat on NAD precursors is about time, not toxicity. NAD+ is used by every proliferating cell, including ones you would rather not support, and there is no long-term human outcome data for chronic NAD precursor use at any dose. The trials are weeks to months Martens 2018 Brakedal 2022. Anyone describing decades of NR use as established is describing a plan, not a dataset.
Betaine at 85 mg is not a safety question; betaine stacking is. Gram doses appear in training supplements, and betaine and choline feed the same microbial trimethylamine route that ends in TMAO Tang 2013 Obeid 2023. The risk is not this capsule, it is this capsule plus a pre-workout plus a choline product, none of which declares the total.
Check the caffeine question yourself. A whole coffee fruit extract is a coffee-derived material and the filed label does not declare a caffeine content NIH DSLD 313910. If you are sensitive, or taking this in the evening, that is a question for the manufacturer.
Who should not take it: anyone pregnant or breastfeeding, since there is no data for NR in pregnancy; anyone with an active malignancy, who should raise NAD precursors with their oncologist rather than decide alone; and anyone buying this expecting the cholinergic or ginkgo-based product the category description implies, because that is not what is in the bottle NIH DSLD 313910.

How you would know if it worked
There is no blood test for this one. That is not a criticism — it is a fact about the effect, and it changes how you should judge it.
- What to watch: One task you do daily and can count. Pages read before you reach for your phone. Emails cleared in a fixed 25-minute block. How far into the afternoon you get before the work stops going in. A blend aimed at attention has to show up in something countable or it has not shown up.
- How long before it means anything: Six to eight weeks, because the bacopa-class ingredients in this category report on that timescale and not before. That is also long enough for a bad fortnight of sleep to land in the middle of your trial, so keep a line for that next to the count.
- What will fool you: Everything else that moves attention, and all of it is louder. Sleep debt, caffeine timing, and whether the work in front of you is interesting will each swamp a nootropic blend. The page says it outright — these work alongside sleep, training and blood sugar rather than instead of them. If one of those three is broken, fixing it removes the need for the trial.
Run it one variable at a time. Starting three things in one week means a result you cannot attribute, which is the same as no result.
Brain Support — safety & side effects
- Read the panel before you read anyone's warnings about it. Thorne's Brain Factors is nicotinamide riboside 415 mg, coffee whole fruit extract 100 mg and betaine 85 mg per capsule — no ginkgo, no huperzine, no alpha-GPC and no bacopa, so the bleeding and cholinergic interactions those four carry do not apply here at all.
- The questions this panel does raise: nicotinamide riboside is cleared by methylation, so a sustained high intake draws on methyl groups — the betaine in the same capsule is a methyl donor, which partly answers it, but it is the thing to watch if your B12 or folate status is poor. Niacin-type flushing is not expected from this form.
- The coffee fruit extract is coffee-derived and the label declares no caffeine content — which is not the same as none. If you are caffeine sensitive, treat the first dose as an unknown and take it in the morning.
- Nothing here has been studied in pregnancy or breastfeeding, and NAD+ precursors are not established in anyone with an active cancer — a fair question for an oncologist rather than a settled answer either way.
The same on every page it applies to. Read it here; it is not repeated research.
- This is one formula with several actives, and it carries the combined safety profile of everything on its panel — the risks do not average out, they add. Check the panel above against anything else you take, because the commonest way to overdose an ingredient is to meet it twice in one day under two different product names.
