Spotlight: B12, Biotin, Selenium & Magnesium Aspartate

If hair regrowth had a backstage crew, these four nutrients would be the ones wearing tool belts and actually getting things done while everyone else takes credit. They’re not trendy, they’re not exotic, and they’re definitely not chosen for marketing sparkle - they’re chosen because your follicles need them.

Let’s break down why these ingredients earn their seat at the table.

Vitamin B12 - the energy supplier

Hair growth is hard work. Your follicles are some of the fastest-dividing cells in your entire body, and they burn through energy like nobody’s business.

That’s where Vitamin B12 steps in.

Why your follicles love B12:

• It helps support healthy cell division, which is essential for hair to grow.

• It helps the follicle stay in the anagen phase (the active growth phase) rather than slipping into rest mode too early.

• It supports good blood flow and oxygen delivery, giving follicles the fuel they need to work properly.

Low B12 often shows up first in your hair - thinning, shedding, slow growth.
Topically delivering it to the scalp means the follicles get support exactly where it’s needed.

Biotin - the keratin coordinator

Biotin has a reputation for being the “hair vitamin,” and for once the reputation is deserved - not because it’s magical, but because it plays a practical role in how hair is built.

Why Biotin matters:

• It helps your body produce keratin, the protein your hair is made from.

• It supports stronger, thicker hair fibres.

• It helps reduce breakage, which is often mistaken for “hair loss.”

Most people think they’re “losing hair” when the truth is their hair is just snapping halfway down the strand. Biotin helps fix that by improving the quality of the keratin itself.

FollicleFood applies Biotin straight to the follicle - no detours, no digestive system middlemen.

Selenium - the quiet scalp-balancer

Selenium doesn’t shout. It whispers - but what it whispers is very important for a healthy scalp environment.

Why Selenium deserves your respect:

• It supports the scalp’s natural antioxidant defences, helping protect follicles from stress.

• It helps maintain the right balance of oils and microflora, creating a healthier environment for growth.

• It supports the production of thyroid hormones, which have a direct influence on hair growth cycles.

Follicles are sensitive little structures - when the scalp is out of balance, they retreat. Selenium helps keep the environment calm so growth can continue.

Magnesium Aspartate - the follicle stabiliser

Magnesium doesn’t get nearly enough credit in the hair world, probably because it sounds too sensible. No one writes breathless magazine spreads about minerals — but your follicles certainly appreciate them.

Why Magnesium Aspartate matters:

• Magnesium supports hundreds of cellular processes, including those involved in hair growth and repair.

• It helps follicles manage inflammation and stress, which often trigger thinning.

• Magnesium Aspartate in particular is more bioavailable, meaning the scalp can actually use it efficiently.

Think of magnesium as the thing that keeps the machinery running smoothly so the more glamorous nutrients (yes, we’re looking at you, B12 and Biotin) can do their jobs properly.

Why these ingredients work better together

On their own, each nutrient is helpful.
Together, they’re a quietly powerful team:

• B12 keeps follicles active and energised.

• Biotin gives them the raw material to produce strong, well-structured hair.

• Selenium keeps the scalp environment healthy and balanced.

• Magnesium Aspartate keeps cellular functions running efficiently and reduces stress.

It’s not one “hero ingredient” — it’s a coordinated support system that helps the scalp return to the conditions where hair regrowth is actually possible.

Matt Miller didn’t throw random vitamins together when he created FollicleFood.
He targeted the actual biological needs of the follicle.

The takeaway

If you want thicker, stronger, more resilient hair, you need more than hype. You need nutrients that:

• support growth

• protect follicles

• strengthen new hair

• create a healthy scalp environment

Vitamin B12, Biotin, Selenium, and Magnesium Aspartate do exactly that - quietly, reliably, and effectively.

This is why FollicleFood isn’t just another pretty bottle.
It feeds the follicles what they genuinely need to start producing better hair.
