FOUNDERS LETTER

FOUNDERS LETTER 

We created f•jacks after realising how complicated getting healthy had become. Every morning felt like a routine of pills, powders and supplements just to feel energised, focused and ready for the day. It was expensive, inconvenient and honestly a bit overwhelming.

We wanted something simpler. An all-in-one functional solution that combined real food with powerful ingredients like adaptogens and mushrooms, all in a bar you could eat anywhere. So we created a smarter, easier way to take the supplements we were already using. 

Today our mission is simple: create functional nutrition made from real ingredients you can recognise, with minimal processing, designed to fit easily into everyday life.

Our bars are made in the UK using all natural ingredients and 100% fruiting body mushroom powders for maximum purity and potency.

From Glory & Tom

How do I know if Boosting bar is right for me?

If you want more reliable energy, sharper focus and better endurance, without relying on caffeine or stacking supplements, f•jacks is for you.

It’s ideal for people who train, work hard, and want a simple, convenient way to support daily performance using real food and functional ingredients.

What products does f•jacks replace?

f•jacks is a convenient alternative to taking multiple performance supplements such as pre-workout powders, energy boosters or bars.

Instead of juggling pills, scoops, and shakes, you get comprehensive performance support in one delicious functional bar.

What's the best way to use f•jacks?

f•jacks is super versatile. Get creative and make it part of your daily routine. 

Enjoy it any time of day: sprinkled over porridge or yoghurt, blended into your smoothies, or simply eaten on its own as a quick, satisfying snack.

For best results, we recommend one 30g serving per day to support long-term benefits.

Can I eat more than one serving per day?

We know f•jacks tastes amazing and it can be tempting to have more than one! While it’s perfectly safe to enjoy a second serving if you want an extra boost, one serving per day is enough to feel the full benefits.

f•jacks, the one week bar.

f•jacks is designed to be your 7-day performance system. Giving you an edge all week long.

f•jacks bars are divided into 7 pre-measured daily sections. Why 7 days? Because real results come from daily consistency and routine, not one-off snacks.

Each serving is loaded with our signature blend of natural actives like Maca root, Ashwagandha, Lion's mane and Chaga. Your week’s worth of functional ingredients in one powerful compact bar. Perfect for travel, gym bags, or office desks. Designed for your daily routine.

Eco-Friendly & Sustainable: Our design cuts down packaging waste by over 85%.

Instead of paying for 7 individually packaged bars, you’re paying for pure ingredients. No fillers or “fluff” used to bulk out smaller daily bars and powders. So you're paying for potency not packaging.

Less packaging = more quality and better value.

What's a supplement bar?

Think of f•jacks as your supplements, reimagined, not just another powder or capsule. Each bar delivers functional ingredients in a convenient, great-tasting snack, so you can eat your supplements instead of swallowing pills or mixing powder drinks.

We created snappable weekly bars becasue we were tired of stacking pills every morning.

What's the best f•jacks for me?

Boosting bar: Your daily ritual for energy, stamina, and drive. With adaptogens like Maca root, Ashwagandha and Tribulus to support endurance, focus and performance naturally.

Brainfood: Your new mental pick me up. Powered by functional mushrooms and adaptogens like Lion’s Mane, Cordyceps, and Rhodiola, it delivers steady, focused energy. Calm, clean fuel for your day.

Our two bars complement each other perfectly.

Why does the packaging say fapjack?

f•jacks is the new name for fapjack. Some packaging may still display the previous fapjack branding. The product itself is exactly the same and is produced by FJACK LTD, the company behind the f•jacks brand.

When can I expect my order to arrive?

Delivery times depend on your location, but we always aim to dispatch orders as quickly as possible, usually within 5 working days as our bars are made fresh to order.

•UK Orders: Typically arrives within 2 working days after dispatch.
•EU Orders: Delivered by your local postal service in 3–5 working days.
•Rest of the World: Delivery times vary depending on customs and local carriers, but every order is fully tracked for peace of mind.

How do subcriptions work?

All f•jacks products are available as subscriptions, so your favourite bars arrive every month, no effort required.

Managing your subscription is simple. Once your order is placed, you can update everything including:

• Changing the products in your next delivery
• Skiping a month
• Updating your personal details
• Adjusting your delivery date
• Cancelling, but we’d love for you to stay and experience the full benefits!
