Focus

Focus Supplement Powder – Zinc

Heads up, eyes up!

THE FACT

Across Europe, 49% of workers are exposed to high-speed work, while 48% experience pressure from tight deadlines¹.

Working quickly and meeting tight deadlines are part of the working day for almost half of European workers.

SOUND FAMILIAR?

Do you finish one task only to find three more waiting for you? Meetings, messages, decisions, deadlines…

Some days, simply maintaining your attention and concentration across everything you do feels like another hard task.

THE BRIDGE

That is why we developed Focus Supplement Powder – Zinc: a powdered formula in sachets containing zinc, vitamin B12, caffeine from guarana, L-theanine from green tea, and lion’s mane, designed for occasional use during periods of high mental demand.

Origin / why

Because some days require extra mental effort. Time to switch focus ON.
Zinc contributes to normal cognitive function, while vitamin B12 supports normal psychological function, in a formula developed to help during occasional periods of high mental demand.

Eye-opening fact

Did you know that, in one study, office workers recorded an average of 25 interruptions during a single working day? Emails, calls, messages, meetings, and conversations can interrupt work throughout the day.

The study also found that the relationship between interruptions and feeling overloaded was stronger when the main tasks were more complex¹ .

02

Myth vs. reality

Myth:
“After an interruption, I can pick up a task exactly where I left off.”

Reality:
When we are interrupted, our attention must shift to a different target before returning to the task we were carrying out. This switch can increase the mental workload associated with the task² .

Top ingredient

Did you know that lion’s mane gets its name from its distinctive appearance?

Lion’s mane (Hericium erinaceus) is an edible mushroom that develops long, white, spine-like structures resembling a lion’s mane³.

9to5 tip

Protect your focus, but protect your breaks too.

Identify the parts of your workday that require the most attention, and try to protect them from interruptions you can control. Silence notifications while preparing a report, avoid switching tasks while checking an order or medication, or set aside a specific time to respond to non-urgent messages and calls. When it is time to stop, take a proper break. Breaks need their own protected space too, particularly during periods of greater mental demand.

FAQs

What is mental fatigue?

Mental fatigue is a feeling of tiredness associated with prolonged or demanding cognitive activity. It may feel like greater difficulty maintaining attention or continuing to perform tasks that require mental effort.

How can I improve concentration during the working day?

Several factors can influence concentration. Getting enough sleep, taking breaks, maintaining appropriate nutrition and hydration, and reducing interruptions while carrying out tasks that require particular attention are some of the measures that may help during mentally demanding working days. A supplement for concentration may also form part of this strategy during occasional periods of greater cognitive demand, provided that its use is adapted to individual needs.

How can I focus at work when I have several competing tasks?

Prioritizing tasks, limiting avoidable interruptions, silencing non-essential notifications, and setting aside specific periods for focused work may help. Proper breaks are also important, as trying to maintain continuous concentration without rest can be counterproductive.

What does L-theanine do?

L-theanine is an amino acid found naturally, primarily in tea leaves. It has been studied both on its own and in combination with caffeine, with some studies reporting favorable findings in measures related to attention and cognitive performance.

What are the potential lion’s mane benefits?

Lion’s mane (Hericium erinaceus) is an edible mushroom that has attracted scientific interest because of its potential role in several areas related to cognitive function. Research in this field is still developing, and the presence of lion’s mane in Focus – Zinc should not be interpreted as an authorized cognitive health claim for this ingredient.
