What this is
Nutrum Brain Booster is a dietary supplement sold in a white 90-capsule bottle. The front label reads "90 Vegetarian Capsules," and the Supplement Facts panel on the back defines one serving as 3 capsules, giving 30 servings in the bottle. It sits in our Supplements range as a capsule-format B-complex and botanical formula rather than a powder, gummy or drink.
The formula is built around three tiers: a six-vitamin B-complex, two free-form compounds listed at named amounts (Alpha-GPC and L-Theanine), and a 1,000 mg proprietary botanical blend the label calls the Nutrum Proprietary Brain Support Blend. Every figure below is transcribed from the Supplement Facts panel on the back of this bottle.
What's inside
Each 3-capsule serving carries eight individually quantified ingredients plus one proprietary blend. Here is what each of them actually is.
- Alpha-GPC (600 mg) — the abbreviated name for L-Alpha-Glycerylphosphorylcholine, spelled out in full on the panel. It is a choline-containing compound, and at 600 mg it is the single largest named ingredient on this label outside the blend.
- L-Theanine (150 mg) — an amino acid found naturally in tea leaves, which is why it turns up frequently in capsule formulas that also contain a caffeine source.
- Thiamin, vitamin B1 (20 mg) and Riboflavin, vitamin B2 (20 mg) — two water-soluble B vitamins, listed here at 1667% and 1538% of the Daily Value respectively.
- Niacin, vitamin B3 (18 mg) — listed at 113% of the Daily Value. The NIH Office of Dietary Supplements publishes a general consumer fact sheet on niacin covering what the nutrient is and where it occurs in food.
- Pantothenic acid, vitamin B5 (5 mg) — supplied as D-Calcium Pantothenate, at 100% of the Daily Value.
- Vitamin B6 (5 mg) — supplied as Pyridoxine HCl, at 294% of the Daily Value.
- Vitamin B12 (50 mcg) — supplied as cyanocobalamin, at 2083% of the Daily Value. Background on this vitamin is available in the NIH fact sheet on vitamin B12.
The remaining 1,000 mg is the proprietary blend, and the panel names its three botanicals without breaking out an individual weight for each one:
- Guarana seed extract — guarana is a climbing plant native to the Amazon basin whose seeds have long been brewed as a stimulant beverage in Brazil. The label carries its own footnote for this ingredient: it contains naturally occurring caffeine.
- Rhodiola rosea (root) extract — standardised on this label to 3% rosavins. Rhodiola is a cold-climate flowering plant that grows in the arctic and mountainous regions of Europe and Asia, with a long history of traditional use in Scandinavia and Russia.
- Panax ginseng (root) extract — the root most people mean by "Asian ginseng," a staple of traditional Chinese preparations for centuries. The NCCIH publishes an independent overview of Asian ginseng, and general background on plant-derived supplements is in the NIH ODS botanical dietary supplements fact sheet. Neither source refers to this product.
Because the blend is declared as a single 1,000 mg total, the split between guarana, rhodiola and ginseng is not disclosed on the label, and we have not estimated it.

How to use it
Follow the directions printed on the bottle. The Supplement Facts panel defines one serving as 3 capsules, and the bottle holds 30 servings across its 90 capsules. The capsules are the swallowable vegetarian type described on the front of the label; they are not chewable and not designed to be opened.
Because this formula includes a caffeine-containing botanical, some people prefer to take stimulant-containing supplements earlier in the day. That is a matter of personal routine, not a label instruction. Keep the bottle closed between uses and out of reach of children.
Who it's for
This is a general-market dietary supplement for adults aged 18 and over, not a product aimed at any particular sex or age group. The 90-capsule bottle is a larger-format option in our supplements catalogue, suiting someone who already knows how they want to use a B-complex and botanical capsule and would rather buy once than reorder monthly.
It will not suit everyone. Anyone who avoids caffeine, is sensitive to stimulants, is pregnant or nursing, is under 18, or takes prescription medication should speak to a healthcare professional before starting it. The same applies if you already take a separate B-complex, since several of the B vitamins here are listed well above 100% of the Daily Value.
Good to know
- Caffeine is present. The label footnote marks guarana seed extract as containing naturally occurring caffeine. A total caffeine figure in milligrams is not printed on this label, so we cannot quote one.
- Vegetarian capsule shell. The front of the bottle says "90 Vegetarian Capsules" and the Other Ingredients line lists a vegetable capsule. The label does not carry a vegan mark, a gluten-free mark or an allergen statement.
- Proprietary blend. One thousand milligrams of the serving is declared as a blend total rather than ingredient by ingredient. That is legal and common, but it does mean the individual botanical amounts are unknown.
- Interactions. Herbal ingredients can interact with prescription medicines. The NCCIH page on dietary and herbal supplements is a reasonable neutral starting point if you want to read around the subject before asking your doctor or pharmacist.
- Keep out of reach of children. As with any supplement, store the bottle where children cannot get to it.
Frequently Asked Questions
How many capsules are in the bottle, and what counts as one serving?
The bottle holds 90 vegetarian capsules, and the Supplement Facts panel defines one serving as 3 capsules — so the bottle provides 30 servings. All the milligram figures on the label are stated for a full 3-capsule serving, not for a single capsule.
Does Nutrum Brain Booster contain caffeine?
Yes. The label carries a footnote against guarana seed extract stating that it contains naturally occurring caffeine. The panel does not print a total caffeine content in milligrams, so anyone monitoring their intake should factor that uncertainty in.
Is this suitable for vegetarians?
The bottle is labelled "90 Vegetarian Capsules" and the Other Ingredients line names a vegetable capsule as the shell material. The label does not carry a vegan certification, a gluten-free mark or any allergen statement, so we cannot confirm anything beyond what is printed.
What is Alpha-GPC, and how much is in a serving?
Alpha-GPC is the short name for L-Alpha-Glycerylphosphorylcholine, and this label lists 600 mg of it in each 3-capsule serving. It is a choline-containing compound, and the panel gives it a dagger symbol because no Daily Value has been established for it.
