Going Dairy Free? Key Nutrients to Watch
Ditching dairy doesn't mean ditching good nutrition. But it does mean paying attention to a few key nutrients that dairy typically provides.
Whether you're lactose intolerant, following a vegan lifestyle, or simply choosing to reduce dairy for health reasons, the good news is that a well-planned dairy-free diet can be completely nutritious. The key word here is "well-planned."
This guide maps the common nutritional gaps and shows you exactly how to fill them with UK-friendly foods, fortified options, and targeted supplements.
The nutrients that matter most
When you remove dairy from your diet, four nutrients deserve special attention. The NHS recognises that dairy products are significant sources of protein and calcium, making replacement essential.
Let's tackle each one systematically.
Calcium: Building strong foundations
UK adults need 700mg of calcium daily. Dairy products provide over 40% of calcium intake in British diets, so removing them creates a significant gap.
NHS Milton Keynes explains: "Cow's milk and dairy products are the biggest sources of calcium for UK diets. Therefore, it is important to ensure enough calcium from alternative sources."
Smart calcium swaps
Fortified plant milks are your easiest replacement. The NHS advises that if you use milk alternatives, "make sure it has added calcium." Look for soya, oat, or almond milk with at least 120mg calcium per 100ml.
Almonds pack a calcium punch. A 30g serving provides around 75mg calcium plus protein and healthy fats. Pure Free From notes that "almonds are your best friend; jam-packed with protein and calcium."
Dark leafy greens like kale, pak choi, and watercress offer easily absorbed calcium. A 100g serving of kale provides about 150mg.
Tinned fish with bones (sardines, salmon) delivers calcium alongside protein. A 100g tin of sardines provides roughly 380mg calcium.
Calcium-rich meal ideas
•Breakfast: Fortified oat milk on calcium-set tofu scramble with spinach
•Lunch: Sardine salad with watercress and almonds
•Dinner: Stir-fried pak choi with tahini dressing
•Snack: Almond butter on wholemeal toast
Our Easy-Move supplement provides targeted bone and cartilage support for those wanting extra assurance.
Iodine: The overlooked essential
This is where many dairy-free diets fall short. Research from the Open University warns: "Replacing cows milk with non-dairy alternatives can put you at risk of not getting enough iodine."
The numbers are stark. Research published in The Lancet found that more than two-thirds of UK schoolgirls aged 14-15 are iodine deficient. Studies show that most milk substitutes contain around 2% of the iodine found in cow's milk.
Iodine solutions
Seaweed is nature's iodine powerhouse. Just 1g of dried seaweed can provide your entire daily requirement. Our OrgaSea combines organic seaweed with vegetables and herbs for convenient daily iodine support.
White fish like cod and haddock provide moderate amounts of iodine.
Eggs from free-range hens offer some iodine, though amounts vary.
Iodised salt can help, but most UK table salt isn't iodised. Check labels carefully.
Weekly iodine strategy
•Include seaweed 2-3 times weekly (nori sheets, wakame in soups)
•Choose white fish twice weekly
•Consider a seaweed-based supplement like OrgaSea
•Use iodised salt when available
Protein: Quality over quantity
The British Heart Foundation explains that "pulses are an inexpensive protein choice, are high in fibre and a source of iron."
The good news? Plant proteins are abundant and often come with extra benefits like fibre and antioxidants.
Top plant protein sources
BBC Good Food lists the highest plant protein sources:
•Hemp seeds: 30g protein per 100g
•Peanuts: 25.8g protein per 100g
•Pumpkin seeds: 24.4g protein per 100g
Lentils are particularly valuable. BBC research shows that "a third of the calories in lentils come from protein, with a half cup providing 13 grams."
Protein-rich meal planning
•Breakfast: NutriShake dairy-free protein shake
•Lunch: Lentil and vegetable soup with hemp seeds
•Dinner: Pea-Nutri protein powder in smoothie
•Snacks: Peanut butter, pumpkin seeds
Our NutriRice rice protein powder offers an easily digestible alternative for those sensitive to soy or pea proteins.
Vitamin B12: The supplement essential
Harvard Health states: "Vegans and vegetarians sometimes have trouble consuming enough B12 since many food sources are found in animal products."
B12 deficiency develops slowly but can cause serious neurological problems. This isn't optional—supplementation is essential for most dairy-free diets.
B12 food sources
Fortified plant milks often contain B12. Check labels for cyanocobalamin or methylcobalamin.
Nutritional yeast provides B12 plus a cheesy flavour that works well in dairy-free cooking.
Fortified cereals can contribute to B12 intake, though amounts vary.
Marmite contains B12, though you'll need about 4g daily to meet requirements.
B12 supplementation strategy
Most nutrition experts recommend a B12 supplement for anyone following a dairy-free diet long-term. Look for:
•10-25 micrograms daily, or
•2000 micrograms weekly
Our GreenNutri blend includes B vitamins alongside 35 organic ingredients for comprehensive nutritional support.
Vitamin D: The sunshine vitamin
Research shows that "there are very few rich natural sources of vitamin D" beyond oily fish and fortified foods.
In the UK, the NHS recommends that everyone consider vitamin D supplements during autumn and winter months.
Dairy-free vitamin D sources
Fortified plant milks increasingly include vitamin D. Soy, almond, and oat varieties often provide 1-2 micrograms per 200ml.
Mushrooms exposed to UV light contain vitamin D2.
Oily fish like salmon, mackerel, and sardines remain excellent sources.
Supplements are often the most reliable option, especially in winter.
Putting it all together
A well-planned dairy-free diet can be nutritionally complete. The key is being systematic about replacements rather than simply removing dairy.
Your daily dairy-free checklist
Morning: Fortified plant milk on fortified cereal or in smoothie Midday: Include a protein source (lentils, nuts, seeds, or protein powder) Evening: Add calcium-rich vegetables (kale, pak choi, broccoli) Weekly: Include seaweed 2-3 times for iodine Daily: Take B12 supplement
Smart shopping tips
Read labels carefully. Not all plant milks are fortified equally. Look for calcium (120mg per 100ml), vitamin D (1-2 micrograms per 200ml), and B12.
Choose variety. Different plant foods provide different nutrients. Rotate between soy, oat, almond, and hemp products.
Consider convenience. Protein powders like our NutriShake or Pea-Nutri make meeting protein needs simple.
When to seek advice
BBC Good Food recommends: "Speak to your GP if you suspect you may be at risk of a nutritional deficiency, including a calcium deficiency."
Consider professional guidance if you're:
•Pregnant or breastfeeding
•Have a child following a dairy-free diet
•Experience fatigue, bone pain, or other symptoms
•Struggle to maintain variety in your diet
The bottom line
Going dairy-free doesn't mean going without essential nutrients. With attention to calcium, iodine, protein, B12, and vitamin D, a dairy-free diet can support excellent health.
The key is planning, not perfection. Focus on fortified plant milks, varied protein sources, regular seaweed intake, and appropriate supplementation.
