“I am 67 and I had started to think the brain fog was just something I had to accept. I was wrong. My word recall is sharper, I feel more present in conversations, and I am not writing everything down anymore because I actually remember things. My daughter noticed before I mentioned it to her.”
Tired after a full night’s sleep? Foggy by 11am? Forgetting words mid-sentence?
The hidden nutritional gap affecting millions of UK adults over 45, and the one supplement form that actually works.
- Restores natural energy so you stop waking up exhausted
- Clears the brain fog that coffee can’t fix
- Brings back the sharp thinking you remember having
- Works even if other B vitamins have failed you
- Contains the active forms your body can actually absorb
- No conversion required, works immediately after absorption

B vitamins are essential nutrients that your body uses to create energy from food and support brain function.
rynw uses methylated B vitamins, the active forms your body can use immediately without having to process them first.
What this means for you:
- More natural energy throughout the day
- Clearer thinking and sharper focus
- Less brain fog, especially in the mornings
- Better word recall and mental sharpness
- Consistent energy without afternoon crashes
The difference: When your body gets B vitamins in the right form, your cells can actually use them to make energy and support your brain. That’s why you’ll feel the difference within weeks.
Modern Life Is Quietly Depleting the B Vitamins Your Brain Runs On.
Today’s lifestyle works against B vitamin absorption in ways most people are never told about.
Chronic stress burns through B vitamins faster than diet alone can replace them. Alcohol blocks the absorption of folate, B1 and B12, even in moderate amounts. Modern diets deliver fewer B vitamins per calorie than they did a generation ago, and plant-based eating leaves B12 almost entirely off the plate.
Common medications quietly add to the problem. Proton pump inhibitors like omeprazole impair B12 absorption. Metformin depletes B12 over years of use. Statins, the contraceptive pill and long-term antibiotics each interfere with the B vitamins your body relies on.
From your forties onwards, the stomach acid needed to release B12 from food begins to decline.
The result is a growing gap between how much B you think you’re getting and how much is actually reaching your brain.
And the brain is only the start. B vitamins are what your cells use to turn food into energy. Without that energy, your organs cannot do the jobs they are meant to do.
Many people describe the same experience: fatigue that sleep doesn’t fix. A mental slowness that appears gradually. Words that disappear mid-sentence. Concentration that used to be easy but now requires effort. Mood that dips for no obvious reason.
These are not signs of ageing. They are often signs of a correctable nutritional gap.
Most B Vitamins Don’t Work. Here’s Why Ours Do.
The B12 in 95% of supplements is called cyanocobalamin, a cheap, synthetic form your body can’t use directly.
Your body has to convert it first. That conversion fails in most adults over 40, especially if you take metformin or acid-reducing medication.
rynw uses methylcobalamin, the active form your body recognises and uses immediately. No conversion required.
Plus, we include high-dose B1 (thiamine), the energy vitamin most B complexes completely overlook.
B1 directly converts glucose into cellular energy. Without enough active B1, your cells literally can’t make energy efficiently. We’ve tested this in clinical trials, the difference in energy levels is remarkable.
The difference:
| ❌ Most B Complexes | ✓ rynw B Complex |
|---|---|
| Cyanocobalamin, must be converted | Methylcobalamin, already active |
| Folic acid, blocked in 40% of people | 5-MTHF, works for everyone |
| Token B1 doses (if any) | Clinical-dose B1 for real energy |
| Cheap fillers | Pure, active ingredients |
Bottom line: If you’ve tried B vitamins before and felt nothing, it wasn’t you. It was the form, and the missing B1.
What Can It Help With?
Eight clinically recognised areas where active-form B vitamins make a measurable difference
B1, B2, B3, and B5 are directly involved in converting food into usable cellular energy. Without active forms, the mitochondrial energy process runs inefficiently.
B12 maintains the myelin sheaths that insulate your nerve fibres. When B12 is low, cognitive processing slows and mental tasks that used to be easy take more out of you.
Difficulty retrieving words mid-sentence is one of the earliest signs of B12 insufficiency. Methylcobalamin supports the neural pathways responsible for word recall.
B vitamins support the production of serotonin and melatonin. Low B6 is associated with disrupted sleep architecture and waking tired despite adequate hours of rest.
B6 in its active P5P form is required for the synthesis of serotonin, dopamine, and GABA, the neurotransmitters that govern emotional stability and motivation.
Metformin depletes B12 by impairing gut absorption. PPIs like omeprazole reduce the stomach acid required to release and convert B12. Both are common in adults over 50.
B3 (niacinamide) supports the NAD+ metabolic pathways that fuel sustained energy production. Without adequate B3, cellular energy becomes uneven, causing the mid-afternoon crash.
Elevated homocysteine is directly associated with accelerated brain tissue loss. The Oxford VITACOG trial showed B vitamin supplementation reduced brain atrophy by over 50%.
What’s Inside, And What It Does For Your Energy
Eight B vitamins in the active forms your body actually uses, not the cheap versions that don’t work.
- ⚡ B1 (Thiamine): Converts food into energy so you stop feeling tired
- ⚡ B2 (Riboflavin): Powers your cellular energy production
- 🧠 B3 (Niacinamide): Supports brain energy and focus
- ⚡ B5 (Pantothenate): Fuels over 100 energy reactions in your body
- 😊 B6 (P5P): Makes the brain chemicals that control mood and energy
- 🔋 B7 (Biotin): Helps your body use fats and proteins for energy
- ✓ B9 (5-MTHF): The active folate form that works for everyone
- 🧠 B12 (Methylcobalamin): The active B12 for nerve health and energy
What to Expect, Week by Week
Managing expectations honestly. Most people notice changes earlier than they expect, and the benefits compound with consistent use.
Active B vitamins begin absorbing immediately
No conversion delay. Some people notice a subtle shift in energy and alertness in the first week, particularly if running a significant deficiency. Others notice nothing yet, this is normal. The vitamins are working at a cellular level before any surface changes are apparent.
First clear changes for most people
Reduced mental fog in the mornings. More consistent energy across the day without the afternoon dip. Some improvement in word recall and concentration. Sleep quality may begin to improve as B6 supports serotonin and melatonin production.
Changes become stable and consistent
Clearer thinking becomes the baseline. Energy feels more reliable. The word-finding gaps that were occurring regularly become infrequent. For those with elevated homocysteine, the neurological support is working at a deeper level.
Long-term neurological maintenance
Daily use supports the maintenance of myelin sheath integrity, sustained homocysteine regulation, and consistent neurotransmitter production. This is daily nutritional maintenance for a brain and nervous system that needs consistent B vitamin availability to function at its best.
