Marobrain label facts: what is printed, what is not
This is the Marobrain label reproduced as documentation, with one honest rule: where the maker prints a number we quote it, and where it does not, the row says so instead of guessing.
The label, line by line
| Ingredient | Amount | Role on the label |
|---|---|---|
| Vitamin B6 (as pyridoxine HCl) | 8.5 mg (500% DV) | Printed in full; nervous system support |
| Vitamin B12 (as methylcobalamin) | 24 mcg (1000% DV) | Printed in full; tiredness reduction |
| Cognitive Proprietary Blend | 151 mg total | Seven botanicals, split not published |
| • Bacopa monnieri (20% bacosides) | Not printed | Memory-linked botanical, studied at higher doses |
| • Rhodiola rosea root | Not printed | Adaptogen; fatigue angle |
| • L-tyrosine | Not printed | Amino acid; stress-performance angle |
| • Theacrine | Not printed | Caffeine-adjacent alkaloid |
| • Theobromine | Not printed | Mild cocoa-family stimulant |
| • Caffeine (green coffee bean) | Not printed | Stimulant; the reason for morning dosing |
| • Huperzine-A (Huperzia serrata, 1%) | Not printed | Cholinergic; small effective doses |
Seven rows saying "not printed" is not this desk being coy: the maker publishes the blend total only, which is common practice and still worth flagging. If per-ingredient milligrams matter to you, that is a legitimate reason to prefer a fully itemized product, and we say so in the evidence review.
The caffeine paragraph, unskippable
Marobrain declares caffeine from green coffee bean inside the blend without printing the milligrams[3]. The practical reading: take it in the morning, skip a second serving, and if you already run on three coffees a day, subtract one rather than stacking. Anyone pregnant, nursing, sensitive to stimulants, or managing blood pressure should clear it with a clinician first - the same sentence we repeat on the answers page because it earns the repetition.
The two printed vitamins
B6 at 8.5 mg is 500 percent of the daily value, and B12 at 24 mcg is 1000 percent - large against DV, modest against supplement practice, and both far below the tolerable upper limits documented by the NIH fact sheets[1][2]. For most buyers over 45, B12 is the more interesting line: absorption declines with age, which is why the vitamin shows up in cognitive formulas at all.
What the maker publishes about quality
Reported as claims, not as this desk's findings: the maker states Marobrain is made in the United States in a cGMP, FDA-registered facility, describes the formula as built on natural ingredients, and sells it as a dietary supplement under the standard FDA framing[4]. Those statements sit on the official page; The Real Shelf has not audited the facility, and no page of this guide should be read as a lab report. What we do verify is the channel - covered end to end in the site check.
