How is this different from other B complex supplements?

Most B complex supplements use synthetic, inactive forms — particularly cyanocobalamin for B12 and folic acid for B9 — that your body must convert before it can use them. Many people, especially those over 40 or on common medications, can't perform this conversion efficiently.

The Vitamin B Complex by rynw uses the active, pre-converted forms of every B vitamin — including methylcobalamin, 5-MTHF and P5P — so your body can use them immediately. No conversion required.

How long until I notice a difference?

Most people notice improvements in energy and mental clarity within 1–2 weeks. By weeks 4–6, sustained improvements in focus, reduced brain fog and better mood are typical. For nerve-related benefits, most people report meaningful improvement at 8–12 weeks. Daily consistency is what determines the result.

Can I take this alongside my other supplements or medications?

B vitamins are water-soluble and generally very well tolerated. If you take metformin, proton pump inhibitors, anticonvulsants or oral contraceptives, we recommend speaking with your GP first — these medications actively deplete B vitamins, which may mean your need for supplementation is even greater.

Why does the form of B vitamin matter?

The form determines whether your body can actually use what you're taking. Standard B12 (cyanocobalamin) requires conversion by stomach acid and enzymes that decline with age and are blocked by common medications. Our methylcobalamin is already in the active state. The same applies to our B9 (5-MTHF vs folic acid) and B6 (P5P vs pyridoxine). Active forms mean the nutrient reaches your cells — not your urine.

How do I take it?

One capsule daily, with or without food. Morning is recommended to support energy and focus throughout the day. Consistent daily use for at least 4–8 weeks is recommended to experience the full benefit.

Is this suitable for vegetarians and vegans?

Yes. The capsule shell is hypromellose — plant-derived. There are no animal products, animal by-products or gelatin of any kind.

Claire Atkinson

"I've been taking this for six weeks and the difference in my energy and focus is genuinely noticeable. I used to hit a wall around 2pm every afternoon, now I just don't. My head feels clearer and I'm actually remembering things properly again. Wish I'd found this sooner."

Energy That Lasts All Day

Adults who took a B vitamin complex for just 28 days lasted 26% longer before exhaustion, with measurable drops in the fatigue chemicals that build up in your blood during physical and mental exertion. Less crash. More capacity. Every day.

Lee MC et al., International Journal of Medical Sciences, 2023

Nerve Pain That Finally Fades

In a direct head-to-head comparison, 73% of people taking methylcobalamin, the active form of B12 in this formula, saw significant improvements in nerve pain, numbness and lost sensation. The group taking standard B12 saw less than half that result.

Li G, Beijing Methycobal Clinical Trial Collaborative Group, 1999

A Sharper, Clearer Mind

Adults who took active B vitamins daily for two years showed significant improvements across memory, executive function and overall mental sharpness, with family members noticing the difference before the participants mentioned it.

de Jager CA et al., International Journal of Geriatric Psychiatry, 2012

Less Stress. Better Mood. Genuine Calm.

215 working adults — none of them clinically deficient — reported significantly higher energy, lower stress and less mental fatigue after just 33 days on a B vitamin complex. No prescription. No stimulants. Just the right nutrients, in the right forms.

Kennedy DO et al., Psychopharmacology, 2010

Here's What No One Tells You About B Vitamin Deficiency...

Deficiencies are very common and few people realise just how much it's holding them back.

B vitamins are not stored in the body. Every single day, your body uses them up and needs them replenished. And the modern world makes that harder than most people realise.

Researchers now believe subclinical B vitamin deficiency — low enough to cause real symptoms, but not low enough to show up clearly on a standard blood test — is far more widespread than previously thought.

You can be eating reasonably well, taking a multivitamin, doing everything right, and still be running low.

Because the problem is not always intake...

It's absorption, depletion, and the forms your body can actually use.

Common signs of mild deficiency:

Persistent fatigue, low energy or muscle weakness
Brain fog, poor concentration, or memory lapses
Low mood, irritability, or heightened anxiety
Difficulty sleeping or waking unrefreshed
Tingling, numbness or discomfort in hands and feet

What causes low levels?

↩ A diet rich in processed foods, refined sugar and refined carbohydrates depletes B1, B2, B3 and B6. Modern food processing strips B vitamins from grains before they reach your plate.

↩ Alcohol actively destroys B1, B2, B3, B6 and B9 — and blocks their absorption in the gut. Even moderate regular consumption reduces your body's stores over time.

↩ Chronic stress and intense physical demand rapidly deplete B5 and B6 — the vitamins your adrenal system depends on to regulate your stress response.

↩ Common medications silently block absorption. Metformin depletes B12. Proton pump inhibitors (omeprazole, lansoprazole) impair B12 and B9. Oral contraceptives deplete B6 and B9. Millions take these daily without knowing.

↩ Age itself reduces your body's ability to absorb B12. Stomach acid and intrinsic factor — the proteins that extract B12 from food — decline naturally from your 40s onwards.

↩ Chronic illness, infection and gut conditions such as IBS, Crohn's and coeliac disease all impair B vitamin absorption at the intestinal level — regardless of what you eat.

Every B Vitamin.
Every Active Form.
One Complete Formula.

Most B complex supplements give you one or two B vitamins and call it a complex. Or they include all eight but use the cheap, inactive forms your body struggles to convert, particularly as you get older.

The published research is clear: B vitamins work better together. Each one supports different pathways: energy, cognition, nerve function, and mood.

Vitamin B1 (100mg)

ENERGY FOUNDATION

Turns the food you eat into energy your brain and body can actually use. Without enough B1, that conversion breaks down, leaving you tired, foggy and running on empty. Clinical trials have shown significant reductions in chronic fatigue with meaningful B1 supplementation.

Vitamin B2 (20mg)

CELLULAR ENERGY

Every cell in your body needs B2 to produce energy. It also activates B6 and folate so they can do their jobs. Without enough B2, neither of them functions correctly, making it the quiet foundation the rest of the formula depends on.

Vitamin B3 (50mg)

CELLULAR ENERGY & FOCUS

Your brain uses 20% of your body's total energy despite being just 2% of its mass. B3 fuels the process that keeps up with that demand, supporting mental stamina, sustained focus and clear thinking. The non-flush form, at a dose that makes a real difference.

Vitamin B5 (50mg)

STRESS & METABOLISM

Your body burns through B5 faster than almost any other nutrient when you're under stress. It supports your adrenal system's response to pressure and helps convert food into usable energy, making it essential for anyone running on little reserve.

Vitamin B6 (10mg)

MOOD, FOCUS & CALM

Your brain needs B6 to produce serotonin, dopamine and GABA — the chemicals that govern your mood, focus and ability to feel calm. Supplied here as P5P, the active form most supplements don't use, ready to work immediately without conversion.

Vitamin B7 (300mg)

METABOLIC COFACTOR

Works quietly in the background to keep your metabolism functioning properly — supporting how your body processes fats, proteins and carbohydrates for energy. A small dose with an outsized role in keeping everything running smoothly.

Vitamin B9 (400mcg)

Neurotransmitter Synthesis

Up to 40% of people carry a gene variant that stops them converting standard folic acid into the form their body can use. This formula uses 5-MTHF — the already-active form that bypasses that step entirely — ensuring B12 has what it needs to work properly.

Vitamin B12 (500mcg)

PRIMARY ACTIVE COMPOUND

The active form of B12 your brain and nerves can use directly — no conversion required. Supports the protective coating around your nerve fibres, neurotransmitter production, and the mental clarity and sharpness that depend on a well-nourished nervous system.

They are mutually dependent. B12 needs folate. B6 needs B2. The full complex, in active forms, covers every pathway simultaneously.

A single B vitamin leaves the rest unaddressed.

What Sets Our Vitamin B Complex Apart?

Most B complex supplements look the same on paper. But there are critical differences that determine whether what you're taking actually works inside your body. Here's why ours stands apart.

Active Forms Only

Most B complexes use the cheap, synthetic forms of B12, folate and B6 — forms your body has to convert before it can use them. That conversion relies on stomach acid and enzymes that decline with age and are blocked by common medications like metformin and omeprazole. Many people are taking them and absorbing almost nothing. Every vitamin in this formula is already in its active, ready-to-use form. What's on the label is what your cells actually receive

All Eight B Vitamins at Meaningful Doses

Most B complex supplements include every vitamin on the label — but at doses so small they make no real difference. It's a common industry shortcut: just enough to list the ingredient, not enough to do anything meaningful. Every B vitamin in this formula is dosed at a level that reflects what published clinical research actually used. Not a sprinkle. Not a fraction. A real, working dose.

The Complete Complex (Nothing Missing)

B vitamins do not work in isolation. B12 requires folate. B6 requires B2. NAD+ production requires B3. Selling you one or two B vitamins and calling it a complete formula is a shortcut that leaves entire metabolic pathways unsupported. This formula provides all eight — because anything less is incomplete by design.

Nothing Hidden. Nothing Unnecessary.

No proprietary blends. No vague 'B complex blend' hiding quantities you can't verify. Every ingredient listed. Every dose disclosed. No gluten, dairy, soy, GMOs, shellfish or artificial additives. The capsule shell is plant-derived. What you see is exactly what you get.

What Real Customers Are Saying

"I'd been running on empty for about two years. Relying on coffee to get through the day, struggling to concentrate, waking up tired no matter how much sleep I got. Three weeks in and it's like someone turned the lights back on. My energy is consistent all day. I genuinely didn't think a supplement could make this much difference."

Verified

Sarah K., 38

"I'm 54 and I'd accepted that the brain fog was just part of getting older. Words going missing mid-sentence, losing my train of thought, forgetting things I'd known for years. Six weeks later I feel sharper than I have in years. The fog has lifted. My husband noticed before I said anything."

Verified

Margaret T., 54

"I work in a high-pressure job and had been struggling with focus and stress for months. I'd tried other B complexes before with zero effect. Someone told me the active forms make all the difference, that's when I found this. Four weeks in, I'm calmer, more focused and actually sleeping better. Night and day compared to what I had before."

Verified

James R., 41

"I've had tingling in my hands and feet for years and my GP pretty much just told me to live with it. Two months on this and it's noticeably better, less tingling, more sensation, and my energy has improved significantly on top of that. I only wish I'd found this sooner."

“After 2 weeks, I noticed less stiffness and more energy. I even stopped taking ibuprofen daily. This has been a game changer for me.”

Verified

Tanya G., 61

I’ve been dealing with stiff joints and general inflammation for years, especially in the mornings. I started taking Bioroot Labs about a month ago, and I can honestly say I feel a real difference. My knees feel less tight, and even my hands usually achy by midday feel more mobile

Do I really need all 8 B vitamins, or just B12?

B12 gets the most attention — but it cannot function properly without the other B vitamins it depends on. B12 requires folate (B9) to complete its neurological functions. B6 is needed for the neurotransmitters that govern mood, focus and calm. B2 activates both B6 and folate. B1 powers cellular energy production. B3 drives NAD+ — the molecule every cell uses for energy and repair. Taking B12 alone while the rest are depleted is like filling one tank while the others run dry. The complete complex addresses every pathway simultaneously.

I've tried B vitamins before and felt nothing. Why would this be different?

The most common reason B vitamins don't work is the form. If the supplement used cyanocobalamin (standard B12) or folic acid (standard B9), your body had to convert them before it could use them — a step many people cannot perform efficiently, particularly those over 40, those on certain medications, or those with the MTHFR gene variant. This formula uses active, pre-converted forms that bypass this entirely. The second most common reason is an incomplete formula — B12 without folate, B6 without B2. This formula provides all eight vitamins at functional doses. Nothing missing.

How long until I feel a difference?

Most people notice improvements in energy and mental clarity within 1–2 weeks. More significant changes, sustained focus, reduced brain fog, improved mood, typically consolidate between weeks 4 and 6. Nerve-related benefits build more gradually, with most people reporting meaningful improvement by weeks 8–12. Consistency matters more than anything else. One capsule, every day.

Is it safe to take alongside my medications?

B vitamins are water-soluble, gentle and generally very well tolerated. However, if you take metformin, proton pump inhibitors, anticonvulsants or oral contraceptives, we recommend speaking with your GP or pharmacist before starting. Importantly, these medications actively deplete B vitamins — which often means your need for supplementation is even greater than average.

Can I take this if I already take a multivitamin?

Yes, in most cases. The B vitamin doses in this formula are set at functional levels, meaningfully higher than the token amounts typically found in multivitamins. Most multivitamins also use inactive forms. Taking this alongside a standard multivitamin is unlikely to cause any concern, as B vitamins are water-soluble and excess is excreted naturally. If in doubt, check with your healthcare provider.

Why does this only have 30 servings per bottle?

Each bottle is a one-month supply at one capsule per day, simple, measurable, easy to maintain. We recommend starting with a 3-month supply to give your body adequate time to restore optimal B vitamin levels and experience the full benefit. Your body has likely been running low for longer than you realise. Give it time to rebuild.

Is this suitable for vegetarians and vegans?

Yes, completely. The capsule shell is hypromellose — plant-derived. There are no animal products, animal by-products or gelatin of any kind in this formula.

What if it doesn't work for me?

Every order is backed by our 30-day money-back guarantee. If you don't feel a meaningful difference in your energy, clarity or overall wellbeing, contact our team for a full refund. No questions asked. The risk is entirely ours.
