Consumer advice
Before buying, ask yourself: Do you actually have a focus problem, or are you hoping a supplement will fix poor sleep, stress, or lack of exercise? If you want to try this, set a realistic 8-week trial period and track specific metrics (e.g., time to complete a task, number of distractions). Don't expect dramatic results—the clinical evidence supports modest, gradual improvements at best. Consider cheaper alternatives like caffeine + L-theanine ($10-15) or a standalone magnesium supplement ($8-12) before spending $20+ on a combination product with hidden doses. If you have kidney disease or take medications, consult a doctor first—magnesium L-threonate and citicoline can interact with certain drugs.

Why the chain breaks for this product
Most ingredients below have real research behind them. The problem isn't the ingredients — it's the doses. 10 of 10 are underdosed compared to the clinical studies, or not disclosed at all, so the product can claim the benefits without delivering the chain that gets you there.

Underdosed: even at the label's max 1 serving/day, it falls short of the research-backed dose.
Brain-supporting compound. Evidence for cognitive recovery after stroke, TBI, and age-related memory decline.
Research-backed dose: 500-2000 mg daily based on study doses
In this product: 250 mg

Magnesium
Magnesium from food poses no health risk in healthy people, because the kidneys clear the excess. High doses from supplements or medications can cause diarrhea, nausea and abdominal cramping, and very high doses can lead to toxicity.
Possible side effects
- High doses from supplements or medications can cause diarrhea, nausea, and abdominal cramping.
- Magnesium carbonate, chloride, gluconate, and oxide are the forms most commonly reported to cause diarrhea.
Serious risks
- Very high doses can lead to magnesium toxicity, with low blood pressure, vomiting, difficulty breathing, irregular heartbeat, cardiac arrest and other signs.
- A few cases of fatal hypermagnesemia have been reported.
- Very large doses of magnesium-containing laxatives and antacids have been associated with magnesium toxicity.
- The risk of toxicity increases with impaired kidney function or kidney failure.
Avoid or ask a doctor first if
- People with impaired kidney function or kidney failure face higher risk of magnesium toxicity.
- People taking medications regularly should discuss their magnesium intake with their health care providers.
Medication interactions
- Magnesium may interact with oral bisphosphonates, tetracyclines, and quinolone antibiotics.
- Some medications, including diuretics and proton pump inhibitors, can affect magnesium status.
Upper limit: 350 mg a day for adults 19+. This label lists 144 mg.
