Gluten or grain free? The critical nutrient you might be missing.

If you’ve made the switch to a gluten-free or low-grain diet, you probably feeling that initial wave of relief. Finally, the bloating has cleared, your energy has bounced back, and your gut is starting started to heal. It feels like a massive victory, and it is. But as we carefully scan ingredient labels and swap out traditional pantry staples, it is incredibly easy to unintentionally create a quiet, unseen gap in our nutrition. While the focus is almost always on avoiding gluten, cutting out whole grains often means unconsciously reducing our intake of vital, fat-soluble nutrients. The most important among them is Vitamin E, a nutritional powerhouse that your nervous system, immune system and muscles rely on daily. If you’ve been feeling fatigued, uncoordinated, or just off since changing your diet, this could be one of the reasons why.

Here is a breakdown of why vitamin E deficiency occurs so frequently in people who are gluten and grain free and the clinical signs to look out for.

Why vitamin E levels drop on a Gluten-Free/Low-Grain diet

Here is a look at the three main reasons Vitamin E drops so drastically when we remove wheat and gluten-based grains from our diet:

We are eliminating the richest natural source

When you decide to cut out gluten or reduce your intake of grains, your primary focus was on gut healing and symptom relief. You scanned labels for hidden wheat, barley, and rye, which is exactly what you should of be doing. But while you are successfully keeping gluten out, you might have inadvertently become deficient in vitamin E. This is because whole grains, especially wheat germ, whole wheat, and bran, are some of the most concentrated traditional sources of alpha-tocopherol (the active form of vitamin E your body prefers). Because vitamin E is fat-soluble, it lives in the germ and the natural oils of these plants. When we eliminate these grains entirely, we remove a massive source of our daily intake.

The gluten free gap

To make a product gluten free, wheat flour in commercial gluten-free breads, crackers, and pastas is replaced by a combination of highly refined starches: white rice flour, tapioca starch, cornstarch, and potato flour.  Unlike whole grains, these ultra-processed alternative starches are completely stripped of their natural oils and germ during milling. Essentially, standard gluten-free processed foods are convenient alternatives, but they are largely devoid of vitamin E.

The fortification gap

This is a huge factor that catches many people off guard. In many parts of the world, standard wheat flours are legally required to be fortified with specific vitamins and minerals to prevent public health deficiencies. However, packaged gluten-free specialty products are rarely bound by these same strict mandatory fortification laws. When you switch to a gluten-free diet, you lose that "safety net" of fortification, meaning your food choices have to become much more intentional to make up the difference.

Malabsorption (the Coeliac factor)

If you switched to a gluten-free diet because of a coeliac disease diagnosis, non-coeliac gluten sensitivity, or general gut dysbiosis (an imbalance in gut bacteria), then you may have issues absorbing fat soluble vitamins.

Gluten damage flattens the tiny, finger-like villi in your small intestine where nutrients are absorbed. Because vitamin E requires healthy fat digestion and a healthy, functional intestinal lining to get into your bloodstream, a damaged gut simply cannot absorb nutrients effectively, even if you are eating plenty of foods rich in fat soluble vitamins. Until your gut fully heals, fat-soluble vitamins (A, D, E, and K) are often the hardest to digest and absorb.

Common symptoms of vitamin E deficiency

Because vitamin E is stored in the liver and adipose (fat) tissue, a deficiency doesn’t usually happen overnight. Instead, it creeps up slowly over months or even years. Vitamin E behaves like a protective shield for your body's cell membranes. It is especially vital for keeping your nervous system, muscles, and eyes safe from oxidative stress and damage. When those shields run low, your body will start sending out distinct SOS signals.

Here are the primary symptoms of vitamin E deficiency to watch out for if you’ve been gluten or grain free for a while:

Neurological signs: balance and coordination Issues

Because vitamin E is critical for the health of your central nervous system, you may experience:

• Unexplained clumsiness (ataxia): You might find yourself tripping more often, fumbling with keys, or feeling slightly off-balance when walking. This happens because the nerves that tell your brain where your limbs are in space are struggling to fire properly.

• Numbness, tingling, or pins and needles: Known as peripheral neuropathy, a lack of vitamin E can cause a dull numbness or a prickly sensation in your hands and feet. As a Coeliac, I experience this from time to time, so I make it a personal priority to optimize my vitamin E intake through food sources like seeds, olive oil and avocado.

Muscle weakness and fatigue

If your morning workouts or even daily tasks like carrying groceries suddenly feel challenging, your muscles might be in need of extra antioxidant protection. Without enough vitamin E, muscle fibers experience higher levels of oxidative damage, leading to:

• Unexplained muscle weakness (especially in the upper arms and legs).

• Premature muscle fatigue or soreness that takes longer than usual to recover from.

Vision changes

The retina at the back of your eye is incredibly rich in light receptors that require a constant supply of vitamin E to stay healthy. You may experience:

• Blurred or diminishing vision: A deficiency can cause these light receptors to degenerate over time, leading to blurred vision.

• Difficulty adjusting to low light: If you find it increasingly hard to see or navigate a dark room or drive safely at night, it could be a sign your retinas are lacking their primary antioxidant shield.

A weak immune system

Do you feel like you are catching every single bug going around? Vitamin E plays a massive role in optimizing your immune response, particularly the function of your T-cells (the cells responsible for fighting off viral and bacterial infections). When vitamin E levels drop, your immune system’s defenses lower, meaning you might get sick more frequently and take twice as long to bounce back.

It is incredibly easy to mistake these symptoms for general fatigue, stress, or a lingering gluten exposure reaction. If you’ve been strictly gluten-free but find that your energy, coordination, or strength still isn't where it should be, it’s time to look past the gut and investigate nutrient deficiencies.

How to replenish vitamin E naturally

The great news is that you do not need to touch a single grain of wheat to optimise your vitamin E levels. In fact, by skipping the processed gluten-free substitutes and focusing on nutrient-dense whole foods, you can easily meet your daily requirements while supporting your overall health.

Because vitamin E is a fat-soluble nutrient, it should be consumed alongside healthy fats to be properly broken down and absorbed by your digestive tract. Thankfully, nature naturally packages vitamin E inside some of the healthiest fats available.

Here are some vitamin E rich foods to include in your diet daily:

• Almonds & sunflower seeds: Just a quarter-cup of dry-roasted sunflower seeds delivers roughly half of your daily requirement, while a handful of almonds provides about 45%.  I try to have nuts and seeds most days. 

• Avocados:  One medium avocado brings about 18% of your daily vitamin E, alongside the monounsaturated fats needed to absorb it perfectly.

• Cold-pressed olive oil: Drizzle extra virgin olive oil over your salads or meals after cooking and they have cooled a bit (when they are not piping hot) this is because heat can degrade vitamin E. I often use olive oil as a dressing over salads and leafy greens to maximize its nutritional value.

• Dark leafy greens: Spinach, Swiss chard, and beet greens are wonderful sources. To get the most out of them, gently cook or sauté them and always pair them with a healthy fat  (e.g avocado, olive oil, nuts, seeds, coconut oil, etc)

A quick note on supplements

If you suspect you are severely deficient, it can be tempting to grab a high strength vitamin E supplement from the health shop, however, it is always best to speak with a practitioner first. High doses of isolated, synthetic vitamin E can sometimes compete with other fat-soluble nutrients (like Vitamin D or K) in the body. Starting with food is safe, effective, and deeply nourishing.

Balancing your plate 

Transitioning to a gluten-free or low-grain diet can be a positive, life-changing step for your gut health and energy levels. However, it isn't just about what we remove from our diet, it’s also about the nutrient-dense food choices we add in.  By making a few small, intentional shifts toward natural fats, nuts, and seeds, and avocado regularly, you can easily close the vitamin E deficiency gap and give your nervous system, muscles, and immune system exactly what they need to thrive.
