🌿
Bacopa Monnieri
Also called: Brahmi, Water Hyssop
An ancient Ayurvedic herb used for thousands of years to sharpen memory and calm anxious minds.
🧠 Focus Tap to flip ↗
Bacopa contains bacosides — compounds that repair damaged neurons and speed up how fast signals travel in your brain. Think of it as patching the wiring and boosting the wi-fi signal at the same time. Takes 4–6 weeks of daily use to hit full effect.
In plain English: It's the librarian for your brain — helps you file information faster and find it again when you need it on shift.

Gotu Kola
Also called: Centella asiatica, Tiger Herb
A herb used across Asia for centuries to reduce mental fatigue and help people stay calm under pressure.
🧠 Focus Tap to flip ↗
Gotu Kola boosts BDNF (Brain-Derived Neurotrophic Factor) — basically fertiliser for your brain cells. It also reduces cortisol spikes, which is why it helps with the mental noise that builds up across a long shift.
In plain English: The noise-cancelling headphones for your brain — cuts the mental chatter so you can hear yourself think in hour 10.

Lutein & Zeaxanthin
From: Marigold extract
Two carotenoids (plant pigments) best known for eye health — but also shown to improve processing speed and memory.
🧠 Focus Tap to flip ↗
Lutein and zeaxanthin accumulate in the macular pigment of the eye and in the brain itself. Studies show they improve how fast your brain processes visual information — relevant when you're operating machinery or reading gauges on shift.
In plain English: Like upgrading your brain's GPU — sharper visual processing, faster reaction to what you're looking at.

🍵
L-Theanine
Found naturally in: Green tea
An amino acid that creates calm, focused alertness — the reason a cup of green tea feels different from a can of Red Bull.
🧠 Focus Tap to flip ↗
L-Theanine increases alpha brain waves — the same waves your brain produces when you're in a calm, focused flow state. When combined with caffeine, it smooths out the spike-and-crash and extends the focus window significantly.
In plain English: Coffee's best mate. Keeps the focus, kills the jitters, stops the 2pm crash. Stack it with your morning brew and you're set.

⚡
Vitamin B12
Also called: Methylcobalamin, Cobalamin
The energy vitamin. Without enough B12, your cells can't convert food into usable fuel.
⚡ Energy Tap to flip ↗
B12 is essential for producing red blood cells, which carry oxygen to your muscles and brain. It also maintains the myelin sheath — the insulation around your nerve fibres. The methylcobalamin form used here is more bioavailable than the cheap cyanocobalamin found in most supplements.
In plain English: The spark plug. Without B12 your engine still turns over but it misfires — fatigue, brain fog, low mood are the warning lights.

🔋
Vitamin B6
Also called: Pyridoxal-5-Phosphate (P5P)
The mood mechanic. B6 helps your body make serotonin, dopamine and GABA — the neurotransmitters that keep you motivated and level.
⚡ Energy Tap to flip ↗
B6 is a cofactor in over 100 enzyme reactions — it's involved in basically everything from protein metabolism to immune function. For shift workers specifically, it helps regulate the body clock by supporting melatonin production.
In plain English: The factory supervisor — makes sure all the chemical production lines in your brain are running on schedule.

🔥
Vitamin B3 (Niacin)
Also called: Nicotinamide, Nicotinic Acid
A key player in converting carbs, fats and proteins into actual energy your cells can use.
⚡ Energy Tap to flip ↗
B3 is used to produce NAD+, a coenzyme found in every living cell. NAD+ is essentially the molecule that makes energy production possible — without enough of it, your mitochondria (the cell's power stations) run slow.
In plain English: The fuel pump. It doesn't provide the energy itself — it makes it possible for your cells to extract energy from the food you eat.

🧬
Folate (Quatrefolic®)
Also called: Methylfolate, B9
The most bioavailable form of folate — your body uses it directly without needing to convert it first.
⚡ Energy Tap to flip ↗
About 40% of people have a genetic mutation (MTHFR) that makes it hard to convert regular folic acid into the active form. Quatrefolic is already in the active form, so it works regardless of your genetics. It's essential for DNA repair and red blood cell production.
In plain English: The premium fuel — skips the refinery and goes straight into the engine. Works even if your body is bad at processing regular folic acid.

🫀
Vitamin B1 (Thiamine)
Also called: Thiamin
The first B vitamin discovered. Critical for converting glucose into brain fuel — your brain runs on glucose, not fat.
⚡ Energy Tap to flip ↗
B1 is the gateway for glucose metabolism in the brain. Without it, the brain literally can't use sugar as fuel properly — leading to fatigue, confusion and poor concentration. Shift workers and heavy coffee drinkers deplete B1 faster than office workers.
In plain English: The gate to the fuel tank. Without it open, your brain can't access the energy sitting right there waiting.

🪨
Magnesium Glycinate
Also called: Magnesium bisglycinate
The most bioavailable form of magnesium — the mineral that tells your nervous system it's safe to relax.
😴 Sleep Tap to flip ↗
Magnesium is a cofactor for GABA — your brain's main calming neurotransmitter. It also regulates cortisol and activates the parasympathetic nervous system (rest-and-digest mode). The glycinate form absorbs without the digestive upset you get from cheaper forms like oxide.
In plain English: The off switch. After a 12-hour shift your brain is still running hot — magnesium is what finally tells it to shut down for maintenance.

Glycine
The "G" in Magnesium Glycinate
An amino acid that binds to magnesium in the glycinate form — and also has its own powerful sleep benefits.
😴 Sleep Tap to flip ↗
Glycine lowers core body temperature — a key trigger for sleep onset. It also inhibits motor neurons during REM sleep (so you don't physically act out your dreams) and reduces daytime fatigue after a poor night. This is why magnesium glycinate works better for sleep than magnesium citrate.
In plain English: The cooling system. Sleep happens when your body temperature drops — glycine pulls the thermostat down and gets the process started.

🌊
Vitamin B5
Also called: Pantothenic Acid
Needed for making Coenzyme A — a molecule involved in basically every metabolic reaction in your body.
💊 General Tap to flip ↗
B5 is needed to make acetylcholine — the neurotransmitter responsible for muscle control, memory and learning. It's also required for producing stress hormones (cortisol) in the adrenal glands, which means deficiency hits hardest in high-stress, high-output environments like mine sites.
In plain English: The multi-tool. You don't notice it when it's there — but everything slows down when it's not.

🧪
Vitamin B2 (Riboflavin)
Also called: Riboflavin-5-phosphate
Helps activate other B vitamins — B6 and folate don't work properly without enough B2 to switch them on.
💊 General Tap to flip ↗
B2 is required to produce FAD and FMN — two coenzymes that sit in the electron transport chain (where your cells actually make ATP, the energy currency of the body). It also recycles glutathione, your body's main antioxidant.
In plain English: The foreman. Doesn't do the work itself — makes sure everyone else on the floor can do theirs.

💅
Biotin (B7)
Also called: Vitamin H
Famous for hair and nails — but its real job is fat and carbohydrate metabolism, especially in the liver.
💊 General Tap to flip ↗
Biotin activates carboxylase enzymes — the enzymes that help process fats, amino acids and glucose. It's not glamorous, but without it your liver struggles to regulate blood sugar, which leads to energy crashes. The hair and nail stuff is a bonus effect of its role in protein synthesis.
In plain English: The unsexy one that matters more than its reputation suggests. Think less hair serum, more metabolic workhorse.
