What each Marobrain ingredient does
Bacopa monnieri: the memory ingredient
Bacopa is the reason Marobrain stands out. In placebo-controlled human trials, most about 12 weeks long, bacopa improved how fast people processed information and improved scores on some recall tests. Marobrain uses an extract standardized to 20% bacosides, the active compounds. Our bacopa guide covers the research in detail.
Huperzine A: the acetylcholine ingredient
Acetylcholine is one of the chemicals the brain uses for learning and memory. Huperzine A, taken from the Huperzia serrata plant, supports healthy levels of it, which is why it shows up in many memory formulas.
Rhodiola, L-tyrosine and the stimulant trio: the focus ingredients
These cover the day-to-day side of thinking. Rhodiola is used for mental fatigue. L-tyrosine is an amino acid studied for keeping focus steady when you are under stress or juggling tasks. Theacrine, theobromine and caffeine from green coffee bean give you a smoother lift in alertness than caffeine alone.
Vitamin B12 and B6: the support vitamins
B12 supports nerve function and brain processing, and B6 helps the body make neurotransmitters such as serotonin and dopamine. They matter most if your levels run low, and they round out the formula.
Seven active ingredients and two vitamins in one daily capsule. It is a full formula, with a 60-day refund policy if it is not for you.
Full refund within 60 days of purchase.
Marobrain side effects
As with any supplement, a few things are worth knowing, based on the ingredients:
- Upset stomach. Bacopa can cause nausea, gas or loose stools in some people. Taking the capsule with a meal helps.
- Jitters or trouble sleeping. The formula has three stimulant ingredients: caffeine, theacrine and theobromine. If you are sensitive to caffeine, take it in the morning.
- Dry mouth, thirst or tiredness. These have been reported with bacopa.
- A fluttering heartbeat. Rare, but stop and call your doctor if you notice it.
Stop taking Marobrain and call your doctor if you feel unwell.
Who should ask a doctor before taking Marobrain
Ask your doctor or pharmacist first if you:
- take blood pressure medicine, heart medicine or blood thinners
- take thyroid medicine or sedatives
- take medicine for Alzheimer's disease or glaucoma, since huperzine A acts on the same brain chemical
- are pregnant, nursing or under 18
- are sensitive to caffeine or have trouble sleeping
The company says the same: check with your doctor first if you take medicine for blood pressure, blood thinners or alpha-blockers.
How to take Marobrain
Take one capsule a day with a glass of water. Taking it with a meal helps if your stomach is sensitive, and the morning is best because of the stimulant ingredients. Each bottle holds 30 capsules, so one bottle lasts 30 days. Bacopa works slowly, so take it every day and give it the full 60 days of your refund window before you decide.
