Quick Summary: Autumn tiredness is caused by reduced sunlight, disrupted sleep cycles, slower metabolism and lower nutrient absorption. Liquid micellized vitamins — especially vitamin B12, CoQ10 and folic acid — absorb faster and more completely than tablets, supporting steadier energy, clearer focus and a stronger mood as the days get shorter.
Why Energy Drops in Autumn
As daylight hours shrink, the body’s internal clock shifts. Reduced sunlight lowers vitamin D and affects serotonin and melatonin levels — hormones that influence mood, sleep and motivation. Cooler temperatures also mean more time indoors, less physical activity and more exposure to seasonal viruses. Comfort-food cravings tend to increase, which can squeeze out nutrient-dense meals.
All of this contributes to the familiar autumn slump.
- Less sunlight → disrupted sleep cycles
- Lower vitamin D → lower serotonin → lower mood
- Reduced movement → slower metabolism
- Comfort foods → fewer vitamins and antioxidants
Personally, I notice the dip every year around the clock change — the first dark Monday morning arrives and everything feels a little heavier and slower. It’s the moment that originally pushed me to look deeper into seasonal fatigue and how nutrition can help soften the edges of it.
Why Older Adults Feel It More
Ageing naturally reduces the body’s ability to absorb nutrients such as vitamin B12, folate and CoQ10. Lower stomach acid and declining intrinsic factor make it harder to extract B12 from food. CoQ10 levels fall steadily with age. Folate deficiency becomes more common and can lead to fatigue, weakness and difficulty concentrating.
For an overview of the symptoms and causes of vitamin B12 and folate deficiency, the NHS provides a clear summary here.
Age-related contributors include:
- Reduced vitamin B12 absorption
- Falling CoQ10 levels
- Higher risk of folate deficiency
- Greater sensitivity to seasonal energy dips
And it’s something I’ve seen time and time again: people in their 40s, 50s and 60s often describe that autumn feels “different” than it used to — not dramatic exhaustion, but a steady drag on energy, motivation and clarity that creeps in earlier each year. Many only realised how much absorption changes with age when they switched from tablets to liquids and finally felt a noticeable difference.
Why Liquid Vitamins Matter — and the Advantage of Micellization
Form is everything when it comes to absorption. Liquid vitamins are already dissolved, meaning they require less digestion and absorb more quickly than tablets.
Micellization, the technology used in Pure Organic Vitamins, breaks fat-soluble nutrients into microscopic, water-friendly droplets called micelles. These micelles mimic how the body naturally absorbs fats, allowing nutrients like vitamin B12, CoQ10 and vitamin E to enter the bloodstream far more efficiently.
When we were first developing our formulas, I tested early versions myself. The difference wasn’t a sudden jolt of energy — it was the steadiness. A clearer head, fewer mid-afternoon dips, and a kind of baseline stability that wasn’t there with tablets. That experience became one of the reasons I doubled down on micellized delivery from day one.
Liquid vs Tablet: Which Absorbs Better?
| Feature | Liquid Vitamins | Tablets / Capsules |
|---|---|---|
| Absorption speed | Fast | Slow |
| Bioavailability | Higher (especially micellized) | Lower |
| Suitable for low stomach acid | Yes | Often no |
| Additives | Minimal | Often many |
| Ideal for older adults | Yes | Less reliable |
The Best Nutrients for Autumn Energy
1. Vitamin B12 + Vitamin E — Natural Support for Energy and Focus
Vitamin B12 plays a direct role in red blood cell formation, nerve support and mental clarity. Even mild deficiency can trigger fatigue, low mood or tingling sensations. Vitamin E provides antioxidant protection, helping your cells handle seasonal stress and oxidative damage.
Our Pure Energy Liquid Vitamin B12 + Vitamin E delivers methylated B12 in tiny micelles for nearly complete absorption — ideal for those with low stomach acid or poor B12 uptake.
2. CoQ10 + Vitamin E — Fuel for Cellular Energy
CoQ10 is essential for ATP (energy) production inside the mitochondria. Natural levels decline with age, contributing to tiredness, sluggishness and slower recovery. Paired with vitamin E, it helps protect cells from oxidative stress while supporting energy output.
Our Pure Vitality Liquid CoQ10 + Vitamin E uses micellization to deliver CoQ10 in highly absorbable droplets, supporting mitochondrial energy production and overall vitality.
3. Folic Acid + Spermidine — Cell Renewal and Daily Vitality
Folate (vitamin B9) is required for DNA synthesis, red blood cell production and metabolic function. Deficiency can lead to weakness, irritability and poor concentration. Spermidine supports healthy cell renewal through autophagy.
Together, they create a strong foundation for energy, fertility health and mid-life vitality. Our Pure Beginnings Liquid Spermidine + Folic Acid combines these nutrients in a high-absorption micellized formula.
Other Helpful Nutrients for Autumn
While not part of our product line, these nutrients play a vital role in mood and energy during the colder months:
- Vitamin D — production drops sharply between October and March in the UK.
- Vitamin C — supports immune function.
- Magnesium — assists with relaxation and sleep quality.
- Omega-3 fatty acids — support mood and cognitive function.
Speak with your GP if you suspect a deficiency or have underlying health conditions.
When to Start Your Autumn Supplement Routine
Don’t wait until fatigue hits. Most people begin feeling the shift from late October onward as days become shorter and colder.
For best results:
- Start in mid-autumn (late October / early November).
- Take your liquid vitamins daily for consistent support.
- Pair supplements with strong lifestyle habits: hydration, movement and quality sleep.
Building a Simple, Effective Autumn Energy Routine
I’ve used a version of this routine myself for the past few autumns, and it consistently helps smooth out the seasonal dip — especially the combination of B12 in the morning and CoQ10 in the afternoon. It’s simple, realistic and easy to stick to even during busier months.
- Morning: Enjoy a light breakfast and take your micellized vitamin B12 + vitamin E drops.
- Midday: Spend 10–20 minutes outdoors to help stabilise your circadian rhythm and support vitamin D synthesis. Hydrate with water or herbal tea.
- Afternoon: Choose a nutrient-dense snack and add your micellized CoQ10 + vitamin E drops.
- Evening: Have a balanced dinner with lean protein and seasonal vegetables, and take your micellized folic acid + spermidine drops.
- Before bed: Reduce screen time to support natural melatonin production and deeper sleep.
FAQs
Why do I feel more tired in autumn?
Reduced sunlight, disrupted sleep cycles, lower vitamin D levels, less physical activity and shifts in diet all contribute to seasonal fatigue in autumn and winter.
Are liquid vitamins better absorbed than tablets?
Yes. Liquid vitamins are already dissolved, so they require less digestion and are typically absorbed faster and more completely than tablets. Micellized formulas further enhance absorption, especially for fat-soluble nutrients.
How long does vitamin B12 take to work?
Everyone is different, but many people notice more stable energy and clearer focus within 3–7 days of daily vitamin B12 supplementation, particularly when using a highly absorbable liquid form.
When should I start vitamin D in the UK?
Public health guidance generally recommends vitamin D supplementation from October to March in the UK, when sunlight is not strong enough for the body to make sufficient vitamin D from the skin.
Final Thoughts
Autumn doesn’t have to mean dragging yourself through darker days. With the right nutrients — and in forms your body can actually absorb — you can maintain steady energy, sharper focus and a more balanced mood all season long.
