The Essential Vegan Supplement Guide: What you might be missing

By choosing a vegan diet you’ve made a conscious decision to focus on plant-based foods. Whatever your personal reasons, it’s a choice that positively impacts the environment and a lifestyle that can have numerous health benefits.  

Complementing your vegan lifestyle with supplements is a proactive step to supporting your body


Why is it important to consider supplements if you’re following a vegan diet?

As with any change to your diet, it’s crucial to be informed and aware. You’re nourishing your body with plant-based goodness, but have you considered the potential gaps in your nutrient intake? There are certain nutrients that can be more challenging to source exclusively from plant-based foods.

However, there’s no need for concern, it’s entirely possible to meet all your nutritional needs on a vegan diet. Nevertheless, being informed about where potential gaps might exist allows you to make even more beneficial choices for your health. By considering supplements, you’re taking a proactive step to ensure your body gets everything it needs.

  • Environmental benefits: By adopting a vegan lifestyle, you play a part in reducing greenhouse gas emissions, conserving water, and decreasing land used for factory farming – all contributing to a healthier planet.
  • Health advantages: Numerous studies suggest that a vegan diet can aid in weight loss, improve kidney function, and lower the risk of heart disease.
  • Nutritional gaps: Despite the benefits, some nutrients like Vitamin B12, Omega-3 fatty acids, and iron might be less prevalent in a vegan diet, necessitating a closer look at supplements.

What are the general health benefits of a vegan diet?

The vegan diet has seen a surge in popularity in recent years, and it’s easy to see why. Plant-based foods, brimming with vitamins, minerals and antioxidants, have the potential to boost your energy, improve skin health, and even aid in chronic disease prevention.

  • Heart health: Consuming legumes, nuts, seeds, and whole grains can lead to better cholesterol levels, reducing the risk of heart disease.
  • Weight management: Vegan diets are often lower in calories, making them an effective option for those looking to shed some weight or maintain a healthy BMI.
  • Digestive health: The high fibre content in plant-based foods promotes regular bowel movements and a healthy gut.
  • Disease prevention: A vegan diet can reduce the risk of certain cancers, type 2 diabetes, and even some neurodegenerative diseases.

But, just like any dietary choice, it’s not without its challenges. To get the most out of your vegan journey, it’s essential to be proactive in ensuring you’re not falling short in certain areas. For example, while plant-based foods offer a plethora of nutrients, some essential elements, such as vitamin B12 – which is primarily found in animal products – might be lacking.

Fortunately, with the right knowledge and quality supplements from trusted brands like Diso, DR.VEGAN, TERRANOVA and Together Health, you can ensure that your body gets all the nutrients it needs to thrive. Transitioning to a vegan lifestyle doesn’t just end with eliminating animal products; it’s about making well-informed choices to support your overall health and wellbeing.

Where might a vegan diet fall short in terms of nutrients?

While your vegan diet will be doing a fantastic job loading you up with fruits, vegetables, grains and legumes, there are certain nutrients that are less abundant or less bioavailable in plant foods.

  • Vitamin B12: Predominantly found in animal products, it’s crucial for nerve function and the formation of red blood cells.
  • Iron: While plants do provide iron (non-heme), it’s not as easily absorbed as the type from animal sources (heme).
  • Omega-3 fatty acids: Essential for brain health, omega-3 fatty acids can be found in seeds like flax and chia, the form we get from plants (ALA) needs to be converted to its active forms (EPA & DHA), and this conversion can be inefficient.
  • Certain minerals: Like calcium and zinc, are abundantly found in dairy and meats, respectively.

How can supplements ensure that a vegan diet is well-rounded and nutritionally complete?

Supporting your dietary choice in the best way possible is easier than you’d think with the wide range of high-quality, vegan-friendly supplements available.

Supplements can act as a safety net, ensuring you’re not missing out on essential nutrients.

  • Targeted nutrition: If blood tests or symptoms indicate a deficiency, supplements provide a direct means to address it.
  • Convenience: For those with busy lives or limited access to diverse vegan foods, supplements can ensure consistent nutrient intake.
  • Enhanced bioavailability: Some vegan supplements are formulated in ways that enhance absorption, ensuring your body can make the most of the nutrients.
  • Supporting overall health: Just as you might add a sprinkle of chia seeds to your smoothie for an omega-3 boost, consider supplements as another tool in your wellness arsenal.

In essence, while a balanced vegan diet can meet most of your nutritional needs, supplements can fill any gaps, ensuring your body thrives just as much as your conscience does.

Why is vitamin B12 so crucial for humans?

B12 is challenging to obtain from a vegan diet

Vitamin B12, often referred to as cobalamin, plays a vital role in numerous processes within your body. Without it, your body would face a number of challenges:

  • DNA production: B12 is a key player in DNA synthesis. Think of it as a backstage crew member, ensuring that the leading actors – your cells – deliver a stellar performance.
  • Nerve function: Imagine if the messages in your brain took longer to reach their destination. Without adequate B12, the protective sheath around your nerves can degrade, potentially leading to long-term neurological issues.
  • Energy production: Ever felt that slump in energy levels? B12 plays a pivotal role in converting the food you consume into energy, fuelling your daily activities.

The consequences of a B12 deficiency aren’t just limited to feeling tired or weak. Over time, a deficiency can lead to more serious health complications, including anaemia and nerve damage.

Why is it challenging to obtain sufficient vitamin B12 from a vegan diet?

The primary sources of B12 are typically animal products. This is because B12 is produced by certain bacteria, and animals often have these bacteria in their systems due to their diet or are supplemented with B12 themselves. Common sources include meat, fish, poultry and dairy, which, if you’ve chosen the path of veganism, are off the menu. So, where does that leave you?

There are some plant-based foods fortified with B12, such as plant-based milks or cereals. However, relying solely on these can be a bit of a gamble. The amount of B12 can vary, and it’s difficult to ensure you’re getting a consistent and adequate amount.

What are the best sources of vegan B12 supplements?

Fortunately, as the popularity of veganism has surged, so has the market for vegan supplements. These ensure that you’re not only meeting but optimising your B12 levels. When choosing a vegan B12 supplement, here’s what to consider:

  • Type of B12: The most commonly recommended form for supplementation is cyanocobalamin. It’s stable and easily converted by your body to the active forms it needs.
  • Dosage: Depending on your needs and any existing deficiencies, the recommended dosage might vary. Always consult a healthcare professional before making decisions on dosage.
  • Complementary ingredients: Some B12 supplements also contain other B vitamins, beneficial for overall energy and wellbeing.
  • Brand transparency: Always opt for brands that offer transparency in terms of ingredient sourcing, production methods, and testing. If you’re seeking suggestions, some renowned vegan supplement brands include Diso, DR.VEGAN and TERRANOVA.

What are the health benefits associated with omega-3 fatty acids?

Algae-based omega-3 supplements are a great choice for those following a vegan lifestyle

Omega-3 fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been the talk of the nutrition world for quite some time now, and rightly so. Their potential health benefits are both broad and impressive.

  • Brain health: Omega-3s are vital components of cell membranes in the brain. They’re linked to improved cognition and a lower risk of degenerative diseases like Alzheimer’s.
  • Heart health: Numerous studies have shown that people who have a higher intake of omega-3s often possess a reduced risk of heart disease. This includes a decrease in bad cholesterol levels, reduced blood pressure, and lesser chances of plaque buildup in arteries.
  • Anti-inflammatory: Chronic inflammation is often silent but is the root cause of many diseases. Omega-3s can reduce the production of substances and molecules linked to inflammation.
  • Eye health: DHA forms a significant component of the retina of your eyes. A deficiency can lead to vision problems.
  • Mood and behaviour: Some researchers believe there’s a link between omega-3s and depression, with these fatty acids playing a role in mood regulation.

Taking all these benefits into account, it’s easy to see why so many nutritionists and health professionals recommend ensuring adequate omega-3 intake in your diet.

How can you obtain omega-3s without consuming fish or fish oil?

Transitioning to a vegan lifestyle often means saying goodbye to traditional sources of omega-3s, primarily fish and fish oil. However, that doesn’t mean you’re left high and dry. There are several plant-based alternatives that can keep your omega-3 levels in the green:

  • Flaxseeds and flaxseed oil: These are excellent sources of ALA (Alpha-linolenic acid), which is a precursor to EPA and DHA. Your body can convert some ALA into EPA and DHA, albeit not as efficiently.
  • Chia seeds: Just like flaxseeds, chia seeds are a top source of ALA.
  • Hemp seeds: Apart from ALA, hemp seeds also contain a good ratio of omega-6 to omega-3, making it a balanced source.
  • Walnuts: Not only are they delicious, but they’re also packed with ALA.

While these sources are great, the conversion rate of ALA to EPA and DHA in the body can be quite low. Therefore, relying solely on them might not provide all the omega-3s your body needs.

Why is algae oil an optimal choice for vegans seeking omega-3 supplementation?

Now, if you’re looking for a direct source of EPA and DHA without going down the fishy route, algae oil is your best bet.

  • Direct source of DHA and EPA: Algae are the primary producers of EPA and DHA in the marine food chain. Fish obtain their omega-3s by consuming algae. By taking algae-based supplements, you’re essentially cutting out the “middle fish” and getting these beneficial fatty acids directly from the source.
  • Environmentally friendly: Farming algae for omega-3 production is more sustainable and has a lower environmental footprint compared to fishing or even fish farming. It also doesn’t contribute to the problem of overfishing.
  • Purity: Algae-based omega-3 supplements, especially from trusted vegan supplement brands, often undergo rigorous purification processes. This ensures you’re consuming a product free from contaminants commonly found in fish, such as mercury.
  • Taste and odour: Let’s face it; not everyone is a fan of the fishy aftertaste that some fish oil supplements can leave. Algae-based supplements are virtually tasteless and odourless.

Given these compelling reasons, if you’re keen on ensuring your omega-3 levels are on point, it’s worth considering algae oil supplements, especially from trusted brands that guarantee purity and sustainability.

What is the difference between heme and non-heme iron?

Supplementation is a convenient way to achieve adequate iron levels on a vegan diet

Iron plays a vital role in our health, but not all iron is created equal. There are two primary types of dietary iron: heme and non-heme. Understanding the distinction between the two is essential, especially if you’re embracing a vegan lifestyle.

  • Heme iron: This type of iron is derived primarily from animal sources, notably red meat. It’s more easily absorbed by our bodies and is often associated with higher iron levels in those who consume meat regularly.
  • Non-heme iron: Predominantly found in plant-based foods like beans, lentils and fortified cereals, non-heme iron is not absorbed as efficiently as heme iron. However, with proper planning, you can still meet your iron needs on a vegan diet.

The variation in absorption rates between these two types of iron can influence your dietary choices and any supplementary needs.

Why might vegans need to be particularly conscious of their iron intake?

Switching to a vegan diet means foregoing the heme iron sources. While plant-based foods are abundant in many essential nutrients, the iron they offer is in the non-heme form, which our bodies find harder to absorb. This fact doesn’t make a vegan diet inadequate; it merely means you need to be a bit more strategic about your iron sources.

Factors affecting non-heme iron absorption include:

  • Phytates in grains and legumes: These can reduce iron absorption, so it’s beneficial to employ methods like soaking, sprouting or fermenting to reduce phytate content.
  • Calcium: While essential for bone health, calcium can inhibit non-heme iron absorption if consumed simultaneously. It’s wise to space out high-calcium and high-iron meals.
  • Vitamin C: On the bright side, vitamin C can boost non-heme iron absorption. Including vitamin C-rich foods like peppers, broccoli, or citrus fruits with your meals can enhance iron uptake.

Being conscious of these factors can ensure you’re maximising your iron intake, even without animal-based sources.

How can vegans effectively supplement iron while ensuring optimal absorption?

Meeting your iron needs as a vegan is entirely achievable, both through diet and if necessary, supplementation. If you’re considering an iron supplement, here are some guidelines:

  • Look for gentle formulas: Some iron supplements can be harsh on the stomach. Look for chelated iron or iron bisglycinate, which are often better tolerated.
  • Monitor dosage: Iron overload can be harmful, so it’s essential not to over-supplement. Always consult with a healthcare professional to determine the right amount for you.
  • Combine with vitamin C: Remember the enhancing effect of vitamin C? Taking your iron supplement with a glass of orange juice or alongside a vitamin C supplement can improve absorption.
  • Avoid taking with calcium-rich foods: Give a gap of about two hours between consuming calcium-rich foods or supplements and your iron supplement.
  • Recheck iron levels: If you’re supplementing due to low iron levels, ensure you periodically recheck levels with your GP to adjust dosage as necessary.

What other supplements might be beneficial for vegans?

When you embark on your vegan journey, it’s essential to ensure you’re covering all your nutritional bases. While B12, omega-3s and iron often steal the spotlight, there are other supplements that can be just as crucial.

  • Calcium: Once synonymous with dairy, calcium is vital for bone health. While plant-based foods like leafy greens, almonds and sesame seeds do offer calcium, the bioavailability can sometimes be lower than dairy sources. So, ensuring you get enough calcium can be a smart move, especially if you’re not regularly consuming fortified foods.
  • Zinc: This mineral plays a central role in immune function, DNA synthesis and wound healing. Foods like legumes, seeds and whole grains are packed with zinc, but the phytates they contain can hinder absorption. Supplementing with zinc can help bridge any potential gaps.
  • Vitamin D: Often called the ‘sunshine vitamin’, vitamin D is crucial for calcium absorption, immune function and mood regulation. While some can get enough vitamin D from sun exposure, it’s not always feasible, especially during winter months or for those living in less sunny climates. There are vegan vitamin D supplements derived from lichen which can be a great addition to your diet.

What should you look for when choosing high-quality, vegan-friendly supplements?

When it’s time to choose a supplement, the options can be overwhelming. Here’s a concise guide to help you navigate:

  • Transparency: The best brands are transparent about their sourcing and manufacturing processes. They’ll offer third-party testing results and will be forthcoming about any additives or fillers used.
  • Vegan certification: Ensure the product is genuinely vegan. Some supplements, especially capsules, can contain animal-derived ingredients.
  • Bioavailability: Look for supplements that boast high bioavailability. This means the nutrient is in a form that’s easy for your body to absorb and use.
  • Clean and ethical: Especially important for the eco-conscious vegan, seek out brands that emphasise sustainable sourcing and ethical production practices. Together Health, Diso and Vegums are examples of brands that prioritise these values.

While a vegan diet offers a plethora of health benefits, it’s vital to be informed and proactive about potential nutrient gaps. Supplements can be an excellent way to ensure you’re providing your body with everything it needs to thrive.

Why is it essential to not over-supplement?

When adopting a vegan lifestyle, it’s only natural for you to ensure you’re getting all the nutrients you need. But just as with any diet, it’s crucial to remember that more doesn’t always mean better. Over-supplementing can lead to various health issues, some of which can be severe.

  • Toxicity: Some vitamins and minerals, when taken in excess, can build up in your body, leading to toxicity. For example, excess vitamin A can damage the liver, while too much zinc might suppress your immune function.
  • Imbalances: Over-consuming one mineral can affect your body’s ability to absorb another. A classic example is the delicate balance between calcium, magnesium, and phosphorus.
  • Side-effects: Many supplements can cause side effects if taken in large doses. For instance, too much iron can lead to constipation or nausea.
  • Expense: Financially, constantly buying and consuming large amounts of supplements can also be unnecessary and costly. It’s in your best interest to get the maximum benefit from the smallest effective dose.

How can you ensure you’re taking the right dosage of supplements?

The right dosage often depends on factors such as age, gender, health status and your diet’s nature. However, there are general guidelines you can follow:

  • Start with food: Before diving into supplements, evaluate your diet. Are there nutrient-rich foods you could be adding to your meals? Foods often contain a complex nutritional profile, which supplements might not mimic.
  • Read the label: Manufacturers typically list the recommended dose on the supplement’s label. Stick to this guideline unless advised otherwise by a healthcare professional.
  • Consult with a professional: It’s a wise decision to talk to a nutritionist or GP. They can provide tailored advice, especially if you have specific health conditions or concerns.
  • Monitor your body: Pay attention to how your body reacts when you start a new supplement. Side effects or changes in your well-being can signal that a dosage adjustment is necessary.

What potential interactions or side effects should vegans be aware of?

When introducing a supplement into your diet, it’s essential to be aware of how it might interact with other aspects of your health:

  • Medication interactions: Some supplements can interfere with the effectiveness of medicines. For example, St. John’s Wort is known to reduce the effectiveness of various medications, including birth control pills.
  • Combining supplements: As mentioned earlier, certain minerals and vitamins can affect each other’s absorption. Combining high doses of calcium and iron, for instance, can diminish the absorption of both.
  • Potential allergies: Some supplements contain ingredients derived from common allergens, such as fish or soy. Always check labels thoroughly if you have known allergies or sensitivities.
  • Digestive issues: High doses of specific supplements, such as vitamin C or magnesium, can cause stomach upset or diarrhoea.

Supplements can be a fantastic way to ensure you’re getting all the nutrients you need on a vegan diet, but it’s crucial to approach them with knowledge and caution. Always seek professional advice, listen to your body and strive for a balanced approach to supplementation.
