D-Biotin (Vitamin B7), The Quiet Nutrient Behind Radiance and Resilience
Some nutrients make noise, all hype and headline. Others simply do the work. D-Biotin, also known as Vitamin B7, is one of those quiet achievers. It’s the kind of nutrient your body relies on daily - for glowing skin, strong hair, clear focus and balanced energy. Yet most of us don’t even realise how much it’s doing behind the scenes.
We include D-Biotin because it strengthens the foundation of wellbeing, how your body converts food into energy, supports your nervous system and nourishes the parts of you that the world can see and the parts it can’t.
What Is D-Biotin?
D-Biotin is the naturally active form of Vitamin B7, a member of the B-complex family. It’s water-soluble, meaning your body doesn’t store it - you have to replenish it regularly through food or supplementation.
While most people know Biotin for its connection to healthy hair and nails, its true impact reaches much further. It plays a vital role in metabolism, helping convert fats, carbohydrates and proteins into usable energy. It also supports enzymes involved in maintaining healthy cells, particularly in your skin, eyes, liver, and nervous system.
01. Skin, Hair, and Nail Strength — from Within
When it comes to visible wellness, Biotin has earned its reputation for a reason. It supports keratin production, the key structural protein in hair, skin and nails.
Low Biotin levels can lead to brittle nails, thinning hair, or dry, flaky skin. Supplementation helps restore these tissues’ resilience, promoting smoother skin texture and stronger, more lustrous hair over time.
At NÆRE, we’re not chasing surface-level beauty. We’re focused on cellular integrity, beauty as the natural reflection of health.
02. Energy Metabolism That Works Smarter
Every cell in your body relies on enzymes that depend on Biotin. Those enzymes drive the conversion of food into ATP, your body’s core energy currency.
Think of Biotin as the quiet operator ensuring that your energy systems are switched on and running smoothly, keeping fatigue low and mental clarity high. (NIH)
When paired with MCTs and B-vitamin cofactors (like B6 and B12), Biotin supports the kind of steady, balanced vitality that defines our approach to nutrition, clarity without chaos.
03. Nervous System and Brain Support
Beyond its beauty benefits, Biotin plays a crucial role in nervous-system health. It supports myelin, the protective sheath that insulates nerve fibres and allows signals to travel efficiently between brain and body.
That connection makes Biotin especially meaningful to us. Research has explored high-dose Biotin (often called MD1003) as a supportive treatment in Multiple Sclerosis (MS), focusing on its potential to aid myelin repair and nerve metabolism. While this is still an emerging area of science, it’s one we follow closely and personally.
Our Founder, Philippa, is a longtime supporter of the MS Society, having witnessed the effects of the disease within her own family. Her university dissertation, “The Invisible Disability,” explored the unseen challenges of MS — and that compassion continues to shape how NÆRE chooses its ingredients: with purpose, integrity, and empathy.

04. Blood-Sugar Balance and Metabolic Health
Some research suggests Biotin may support glucose metabolism by improving how the body uses insulin and breaks down carbohydrates. For those managing energy fluctuations or blood-sugar stability, Biotin can contribute to smoother daily performance without the crash.
05. Why D-Biotin, Not Just “Biotin”
Not all Biotin is equal. D-Biotin is the biologically active, naturally occurring form, the one your enzymes recognise and use. Synthetic or racemic versions can be less efficient. That’s why we only use D-Biotin in NÆRE: the form proven to work harmoniously with your body, ensuring consistent delivery and measurable benefit.
Why It Belongs in NÆRE
We designed NÆRE to bridge the gap between clinical integrity and daily nourishment. D-Biotin embodies that philosophy it’s not flashy, but it’s fundamental.
We include it because it supports:
Visible health - stronger hair, skin, and nails
Core energy metabolism
Nervous-system stability
Blood-sugar balance
Long-term neurological health
D-Biotin may be a micronutrient, but its impact is anything but small. It sits quietly at the crossroads of beauty, energy and neurological health. It’s the kind of ingredient that reminds us why we do what we do: to help you feel stronger, think clearer and shine brighter, inside and out.
