What are functional mushrooms?

Functional mushrooms, also known as medicinal mushrooms, include varieties such as Reishi, Lion’s Mane and Chaga. They have been used in Asian medicine for centuries for health benefits, and are now popular in Western wellness for supporting immunity, energy, focus, cognitive performance, sleep, and recovery.

How are functional mushrooms extracted?

Mushrooms are dried, ground into powder, and then extracted using hot water or alcohol. Fourfive uses a dual-extraction process to capture beta-glucans (from water) and triterpenes (from alcohol), resulting in highly concentrated 10:1 ratio mushroom extracts that are more potent than non-extracted powders.

How should I use functional mushrooms?

Since raw mushrooms are hard to digest, fourfive provides dual-extracted mushroom powder in capsule form, ensuring high potency and easy absorption. While teas and powders exist, they are usually non-extracted and contain far fewer beneficial compounds.

What mushroom supplements should I take?

fourfive offers a range tailored to different needs: Lion’s Mane: Energy & Focus for concentration and brain function, Reishi: Bedtime Blend for relaxation and sleep support, and Multi Mushroom: Ultimate Blend for a convenient all-in-one health supplement.

Can I use more than one mushroom supplement a day?

Yes, you can combine mushroom supplements depending on your goals. The AM+PM Bundle pairs Lion’s Mane for daytime focus with Reishi for evening relaxation. Always follow recommended dosages and consult a healthcare professional if unsure.

What is the best time of day to take mushroom supplements?

Lion’s Mane is best taken in the morning to support energy, focus, and performance. Reishi is better suited to evenings as it encourages relaxation, sleep, and recovery.

Can you mix CBD and mushrooms?

Yes, fourfive mushroom supplements can be combined with CBD products. Many people find this pairing enhances balance, recovery, and wellbeing. Consult a healthcare professional before adding new supplements if you have health conditions or take medications.

Are functional mushrooms psychoactive?

No, functional mushrooms are not psychoactive and do not cause hallucinations. They are safe for most people when taken responsibly, though it’s always wise to seek professional guidance if you have existing health conditions.

What are Fourfive Lion’s Mane Mushroom Energy & Focus Capsules?

These are daily capsules that combine a potent 10:1 Lion’s Mane mushroom extract with supporting botanicals and vitamins to help support mental clarity, focus, brain function, and steady energy without relying on stimulants like caffeine.

What is Lion’s Mane?

Lion’s Mane (Hericium erinaceus) is a functional mushroom that has been studied for its potential to support cognitive function and mental clarity. Each capsule contains a high-strength 10:1 extract, equivalent to 4,000 mg of Lion’s Mane mushroom, designed to support optimal brain and overall performance.

How can these capsules support my focus and energy during the day?

Lion’s Mane supports mental clarity and cognitive performance, helping you stay switched on during work, training, or busy days. The formula also includes:

• Bacopa Monnieri to support memory, learning, and mental resilience,

• Guarana as a natural source of smooth energy,

• Maca Root to support stamina and daily energy,

• Vitamins B6 and B12 to help convert food into energy and reduce tiredness and fatigue.

Together, these ingredients help with focus and productive energy without the sharp spikes or crashes that come from strong stimulants.

Will this feel like caffeine or a stimulant?

No. Although Guarana provides a gentle energy lift, this formula is not designed to feel like a heavy stimulant. Instead, it supports steady mental energy and focus in a way that feels natural and lasting rather than jittery or forcing you up.

Are these capsules good for long work days or training?

Yes. This blend of ingredients supports both cognitive and physical energy demands, making it useful on work days, training days, or when life feels especially full.

Will these capsules affect my sleep?

No, this product should not impact your sleep. Lion’s Mane and the other ingredients support mental clarity and energy during the day rather than stimulating at night. Taking them earlier in the day helps avoid any potential interference with sleep.

Is this product tested?

Yes. Lion's Mane Energy & Focus capsules are made in the UK and third-party tested for quality, purity, and consistency. Additionally, the capsules are Informed Sport tested, meaning each batch is independently screened for substances banned in sport.

Informed Sport testing provides an extra layer of assurance that the product has been rigorously tested for contaminants and unwanted substances, offering greater confidence in its quality, purity, and label accuracy.

What’s the difference between Lion’s Mane Mushroom Gummies and Lion’s Mane Mushroom Capsules?

Both the Lion’s Mane Gummies and Capsules provide 4000 mg of Lion’s Mane per serving. The difference comes down to format and supporting ingredients.

The gummies are simple and easy to take, combining Lion’s Mane with vitamin B5 to support mental performance and energy in a gentle, chewable format. They are ideal if you want a straightforward daily habit.

The capsules include additional ingredients like Bacopa Monnieri, Guarana, Maca Root, and B vitamins to support memory, focus, and sustained energy. They are better suited if you want a more layered formula for busy or demanding days.

Is this product suitable for vegans and free from allergens?

Yes. The capsules are vegan-friendly and free from common allergens, including dairy, gluten, and nuts.

If you have any concerns then please contact contact@fourfive.com.

When should I take Lion’s Mane capsules?

Most people take them in the morning or early in the day when they want help with focus and mental clarity. They can be taken with or without food and fit easily into a daily routine.

Can these help with brain fog?

Many of our customers, particularly women going through menopause and postmenopause say they feel more clear and focused after adding Lion’s Mane Energy & Focus to their routine.

These ingredients are combined to support cognitive performance, focus, and natural energy levels. Vitamins B6 and B12 also contribute to normal energy-yielding metabolism and normal psychological function.

Supplements to support menopause.
