The gut is often called the 'second brain'. Your gut and brain are in constant conversation — and not just about snacks. They’re linked through something called the gut-brain axis, a powerful communication pathway made up of nerves (like the vagus nerve), hormones, and even gut microbes.

Your gut produces around 90% of your body’s serotonin — a key mood-regulating chemical — which means your digestive system plays a huge role in how you feel mentally and emotionally.

In short: when your gut is happy, your brain feels it too. That’s why FHIRST is designed to support both — with ingredients that nourish your microbiome and help lift your mood.

Gut health isn’t just about digestion anymore. It’s about mental clarity, energy, and emotional balance — all starting from the inside out.

Think of your gut like a party — and your good bacteria are the VIP guests. Probiotics are the live, beneficial microbes that help keep things running smoothly. Prebiotics are the fibers that feed those microbes and help them thrive.

Together, they’re the ultimate duo:

PRObiotics bring the benefits — like supporting digestion, reducing bloating, and keeping your gut bacteria balanced.

PREbiotics keep them fueled and happy, so they can do their thing more effectively.

A well-fed, well-balanced gut microbiome doesn’t just support digestion — it’s also linked to mood, immunity, and overall wellbeing.

That’s why FHIRST includes both, in science-backed doses, to give your gut (and your whole vibe) the love it deserves.

Magnesium: the hero mineral

If magnesium were a sibling, you’d tell it to stop being such an overachiever and showing you up in front of your parents all the time. It really is the do-it-all nutrient, supporting muscle recovery for gym bunnies, a zen-like state for the highly strung, and sounder sleep for those who sometimes struggle to fall aslee… Zzz.If you’re not a gym bunny/ highly strung/ sleep shy, magnesium powers more than 300 of your body’s biochemical processes, so trust me, there’s a place for it in your life.

It’s also known for:

+Sharpening your focus + Supporting healthy bones + Balancing the levels of charged electrolytes (vital minerals) + Fuelling your workout

Oh and we choose the mightiest one: Magnesium glycinate! It's one of the most bioavailable and gentle forms of magnesium — meaning your body absorbs it easily, without the digestive drama.

It’s known for its mood boosting effects, helping support mood, sleep, and stress balance — which makes it the perfect functional sidekick in FHIRST for anyone chasing good vibes and inner strenght.
