Why B Vitamins Are Essential for Energy Production

Are you someone who reaches for another coffee or energy drink just to make it through the day?

You’re not alone. In our fast-paced world, feeling low on energy has almost become normal. But what your body really needs isn’t another quick fix, it’s lasting, sustainable energy that helps you feel clear, focused and balanced from morning to night.

And that’s exactly where B vitamins come in.

These often underestimated nutrients are essential players in your body’s energy production process. While they don’t give you energy in the way caffeine does, they’re absolutely crucial for turning food into fuel. Without them, your body simply can’t produce energy efficiently, no matter how healthy your diet looks on the surface.

What Do B Vitamins Actually Do?

The B vitamin family includes eight different vitamins, each with its own role, but they work best as a team. Together, they support everything from energy metabolism to brain function and emotional balance.

Here’s a quick look at who’s who:

• B1 (Thiamine): Helps turn carbs into energy.

• B2 (Riboflavin): Important for red blood cells and cell protection.

• B3 (Niacin): Supports skin health and energy release.

• B5 (Pantothenic Acid): Assists hormone production and energy conversion.

• B6 (Pyridoxine): Key for mood, sleep and immune function.

• B7 (Biotin): Supports metabolism and healthy skin/hair.

• B9 (Folate): Essential for cell division and blood formation.

• B12 (Cobalamin): Critical for nerves, mental clarity and red blood cells.

They don’t contain energy, but they help your body create it from the food you eat.

How B Vitamins Help You Create Energy

Think of food as fuel and B vitamins as the spark that helps your body use that fuel. They work as coenzymes, helping enzymes in your cells do their job: turning carbohydrates, fats and proteins into ATP, the energy your body runs on.

If you're low in B vitamins, you might feel:

• Constantly tired or sluggish

• Mentally foggy or unmotivated

• Moody, irritable or low

• Slow to recover after stress or exercise

Everyone’s needs are different. Some people naturally need more, especially during busy or stressful times.

Are You Getting Enough B Vitamins?

Here are a few signs that you may need more B vitamins:

• You’re under chronic stress

• You follow a vegan, vegetarian or restricted diet

• You’re pregnant or breastfeeding

• You take certain medications (like antacids, birth control or metformin)

• You often feel tired, low or mentally foggy

The good news? B vitamins are water-soluble, so your body uses what it needs and gets rid of the rest. But because they aren’t stored long-term (with one exception — see below!), you need to replenish them daily.

Spotlight on Vitamin B12: Easy to Miss, Hard to Replace

Vitamin B12 is essential for keeping your energy levels, nervous system, and red blood cells working properly. But here’s the thing, many people don’t realise they’re low in B12 until symptoms show up.

That’s because your body stores B12 in the liver, often in large amounts. It can take years for that supply to run out. But once it does, you may suddenly feel:

• Tired and low in energy

• Foggy-headed or forgetful

• Moody or low

• Numbness or tingling in your hands and feet

• Weak or dizzy

• In serious cases, even problems with balance or movement

Studies show that 1 in 10 men and 1 in 4 women aren’t getting enough B12. Among young women (ages 14–24), it’s as many as 1 in 3.

Why the difference?
B12 is found mostly in animal foods like meat, fish, eggs and dairy. And women, especially younger women, tend to eat less meat than men. People who follow a vegan or vegetarian diet are also more likely to be low in B12.

But even if you do eat these foods, there’s another challenge: your stomach needs a special helper to absorb B12 properly.

What Is “Intrinsic Factor” And Why Does It Matter?

To absorb B12 from food, your stomach makes a protein called Intrinsic Factor. It acts like a key, helping B12 get through the digestive system and into your bloodstream.

But if your body doesn’t make enough Intrinsic Factor, you may still become deficient, even if you eat enough B12.

This can happen if you:

• Have digestive issues like chronic heartburn or gastritis

• Take certain medications (like antacids or metformin)

• Are over 50 (your stomach naturally produces less Intrinsic Factor with age)

• Have had stomach surgery or autoimmune conditions

That’s why many people benefit from B12 supplements, especially if absorption is a concern.

Why High-Dose B12 Supplements Can Help

Your body can only absorb a small amount of B12 at once, even less if Intrinsic Factor is low. But there’s a clever workaround: when you take a high enough dose, a small amount can still be absorbed passively (without Intrinsic Factor) through the gut lining.

That’s why our B-complex contains 300 μg of B12, a carefully chosen amount that ensures your body gets what it needs, whether or not Intrinsic Factor is doing its job.

And don’t worry, B12 is water-soluble, which means your body gets rid of what it doesn’t use.

Best Food Sources of B Vitamins

You can get many B vitamins from food, especially if you eat a varied, whole-food diet. Some great sources include:

• Leafy greens & legumes: great for folate (B9)

• Whole grains & seeds: contain B1, B3 and B5

• Eggs & dairy: good for B2, B7 and B12

• Fish & lean meats: rich in B6, B12 and niacin (B3)

• Nuts & mushrooms: support B3 and B5 levels

But if your diet is limited, or if absorption is an issue, supplementation can help.

When Should You Take B Vitamins?

B vitamins are best taken:

• In the morning: to support natural energy levels

• With food: to help with absorption

• Every day: because your body doesn’t store most of them

Energise from the Inside Out

Energy isn’t just about willpower, it’s about biology. And at the centre of that process are B vitamins, working quietly in the background to keep your body and brain powered.

So if you’re feeling tired, unfocused or a little off, start small. Start with the basics. Start with B.

Your cells will thank you.
