If you're over 50 and struggling with brain fog, low energy, or poor word recall — this might be the most important thing you read today.
Most B12 supplements use cyanocobalamin — a synthetic form your body has to convert before it can use it. After 50, that conversion becomes less efficient.
The Vitamin B Complex by rynw uses methylcobalamin — the active form. No conversion needed. It goes to work immediately.

I've been taking this for 6 weeks now and the difference is remarkable. My husband noticed before I did — he said I seemed "more present" in conversations. I'm 64 and I genuinely feel sharper than I did at 55.

I take omeprazole and my pharmacist told me it blocks B12 absorption. Started rynw 8 weeks ago and the difference in my energy is night and day. No more 3pm slump.

I was so tired all the time — my GP said my B12 was "borderline low". Started this 10 weeks ago and I feel completely different. More energy, better mood, sleeping properly. 10/10.

Cognitive Clarity
The Words Come Back. The Fog Lifts.
B12 deficiency is one of the most under-diagnosed causes of cognitive decline in adults over 50. Methylcobalamin — the active form used in rynw — supports myelin sheath integrity, which is the protective coating around your nerve fibres responsible for sharp, fast thinking.

What's Inside
Every Ingredient. Every Form. Every Reason.
We use active, bioavailable forms — not the cheap synthetic versions most brands rely on.
Methylcobalamin B12
Active Form · 1000mcg · 40,000% NRV
The active form your body uses directly. No conversion required. Supports nerve function, energy metabolism, and cognitive clarity.
Methylfolate B9
Active Form · 400mcg · 200% NRV
Bypasses the MTHFR gene mutation that prevents 40% of people from converting folic acid. Supports mood, DNA repair, and red blood cell formation.
Pyridoxal-5-Phosphate B6
Active Form · 10mg · 714% NRV
The active form of B6. Supports neurotransmitter synthesis — serotonin, dopamine, GABA. Critical for mood regulation and cognitive function.
Niacin B3
Nicotinamide · 18mg · 113% NRV
Supports NAD+ production — the molecule your mitochondria use to generate cellular energy. Nicotinamide form avoids the flushing effect.
Riboflavin B2
1.4mg · 100% NRV
Activates B6 and folate, making them usable by the body. Essential for energy metabolism and reducing oxidative stress.
Thiamine B1
1.1mg · 100% NRV
Supports carbohydrate metabolism and nerve signal transmission. Deficiency is strongly linked to fatigue and cognitive impairment.
Pantothenic Acid B5
6mg · 100% NRV
Supports the synthesis of coenzyme A, required for energy production and metabolism of fats, carbohydrates, and proteins.
Biotin B7
50mcg · 100% NRV
Supports fatty acid synthesis and amino acid metabolism. Also supports healthy hair, skin, and nails as a secondary benefit.

Common Questions
Everything You Need to Know
What makes rynw different from other B complex supplements?
Most B complex supplements use synthetic, inactive forms — cyanocobalamin for B12, folic acid for B9, pyridoxine HCl for B6. Your body has to convert these before it can use them, and that conversion becomes less efficient as you age. rynw uses the active, bioavailable forms — methylcobalamin, methylfolate, and pyridoxal-5-phosphate — that your body can use immediately, without conversion.
How long before I notice a difference?
Most people notice an improvement in energy and mental alertness within 1–2 weeks. More substantive changes — reduced brain fog, better word recall, clearer thinking — typically appear between weeks 4 and 8. We recommend a minimum of 90 days for full sustained benefit.
I take metformin or omeprazole. Is this suitable for me?
Yes — and you are among the people most likely to benefit. Metformin is clinically documented to deplete B12 over time. PPIs like omeprazole reduce stomach acid, which is required to convert synthetic B12 supplements. Methylcobalamin absorbs without these dependencies. Please consult your GP if you have any specific concerns.
Are there any side effects?
B vitamins are among the safest and most well-tolerated nutrients available. Being water-soluble, any excess is simply excreted. A very small number of people experience mild digestive settling in the first few days — taking the capsule with food resolves this in almost all cases.
How do I take it?
One capsule each morning with a glass of water. Can be taken before or after food. That is the entire routine.
What if it doesn't work for me?
You are covered by our 30-day money-back guarantee. If you do not feel a meaningful difference in your energy, mental clarity, or overall wellbeing within 30 days, contact us for a full refund. No questions asked. The risk is entirely ours.
Can I cancel my subscription anytime?
Yes. You can delay, pause, or cancel your subscription at any time — no fees, no questions, no minimum commitment. Simply log in to your account or email us and we'll handle it immediately.
Our 30-Day Money-Back Guarantee
We want you to be completely satisfied. If you do not feel a meaningful improvement within 30 days — for any reason — simply email us and we will issue a full refund. No questions asked. The risk is entirely ours.
