A Natural Addition to Your Pre and Post Workout Routine

When you think about food for running, cycling, swimming or an active day outdoors, seaweed probably is not the first ingredient that springs to mind.

Carbohydrates, protein, water and electrolytes usually take centre stage, and rightly so. Your body needs carbohydrates to fuel exercise, fluid to stay hydrated and protein to help repair and maintain muscle after training.

Seaweed does not replace any of these essentials. What it can do is bring a naturally varied mix of minerals, fibre, vitamins and flavour to the meals you eat around your training.

Whether you are preparing for a long run, recovering from a workout or simply trying to eat well while leading a busy, active life, seaweed is an easy ingredient to work into your everyday routine.

Is seaweed a workout fuel?

Seaweed is better thought of as a supportive food than a primary source of exercise fuel.

Before a longer or more demanding workout, your main source of energy should usually come from carbohydrate-rich foods such as oats, rice, pasta, potatoes, bread or fruit. After training, carbohydrates help replenish energy stores, while protein supports muscle maintenance and repair. Staying properly hydrated before, during and after exercise is equally important.

Seaweed can be added to these meals to introduce extra minerals, fibre and a naturally savoury flavour. Rather than eating it on its own and expecting an immediate performance boost, combine it with the foods your body already needs.

Think pasta with Sea Spaghetti, eggs sprinkled with Sea Salad, a rice bowl finished with seaweed flakes or a smoothie blended with a small amount of Ocean Greens.

Seaweed before exercise

Supporting normal muscle function

Different seaweeds naturally contain minerals such as magnesium and potassium. These nutrients contribute to normal muscle function, while magnesium also contributes to normal energy-yielding metabolism.

That does not mean a sprinkle of seaweed will instantly make you faster. It simply means seaweed can contribute useful nutrients as part of a varied diet that supports an active body.

Our Mixed Seaweed Flakes Shaker, made with Kelp and Sea Spaghetti, is a particularly simple option. Add it to eggs, soups, rice, roasted vegetables or a pasta sauce as part of your regular meals. The blend naturally contains minerals including magnesium, potassium, calcium and iron, as well as dietary fibre.

Iodine and normal energy metabolism

Seaweed is one of the best-known natural dietary sources of iodine.

Iodine is needed by the body to produce thyroid hormones, which help regulate normal metabolism. Approved nutrition claims also recognise that iodine contributes to normal energy-yielding metabolism.

This makes iodine an important nutrient, but more is not necessarily better. The amount found in seaweed varies between species, so it is important to follow the serving guidance provided with each product.

Our Kelp Shaker offers an easy way to introduce a small amount of kelp to cooked meals. Try adding it to soups, broths, beans, stews or rice rather than taking large, unmeasured amounts.

Anyone who has been advised to restrict iodine, is receiving thyroid treatment or takes thyroid medication should speak to their doctor, pharmacist or dietitian before regularly using iodine-rich foods or supplements.

Minerals are only one part of hydration

Seaweed naturally contains minerals often associated with electrolyte balance, including sodium, potassium and magnesium. However, eating seaweed is not a replacement for drinking enough fluid.

For shorter, easier sessions, water and a balanced diet may be all you need. Longer workouts, hot conditions and particularly sweaty sessions may require a more considered hydration and fuelling plan.

Seaweed can contribute to the wider picture, but it should sit alongside regular fluids rather than being treated as a hydration product.

What should you eat before a run or workout?

The closer you are to exercising, the simpler your food may need to be.

Seaweed contains dietary fibre, which can be helpful as part of your everyday diet but may not suit everyone immediately before running. A large, high-fibre meal just before a hard session could feel uncomfortable, particularly if you are prone to digestive problems.

For a substantial meal two or three hours before training, you could try:

• Pasta mixed with rehydrated Organic Sea Spaghetti
• Rice, vegetables and a source of protein finished with Sea Salad flakes
• Eggs on toast with a small sprinkle of Mixed Seaweed Flakes
• A baked potato with tuna, beans or cottage cheese and a little Dulse or Sea Salad
• A smoothie containing fruit, yoghurt or milk and a small amount of Ocean Greens

Ocean Greens, also known as sea lettuce, can be added to smoothies, salads, soups and rice dishes. They contain dietary fibre and naturally occurring minerals including iron, magnesium, potassium and iodine.

Before an important event or long run, always practise your food routine during training. Race morning is not the time to discover that your stomach dislikes a new ingredient.

Seaweed after exercise

After a run, gym session or long active day, your body needs food, fluid and rest.

Your recovery meal should normally include carbohydrates to replenish energy stores and a suitable source of protein. Seaweed can then be used to add flavour, texture and a broader range of nutrients.

Pair Sea Spaghetti with carbohydrates and protein

Our Organic Sea Spaghetti is naturally high in dietary fibre and protein and contains minerals including calcium, iron, magnesium, potassium and iodine. It can be cooked alongside traditional pasta, added to stir-fries or used in salads, soups and broths.

It works particularly well in a post-workout meal because it can be combined with familiar sources of carbohydrates and protein.

Our Sea Spaghetti ‘Tagliatelle’ with Crab recipe brings together Sea Spaghetti, vegetables, crab, tomato and lemon in a fresh but satisfying dish.

For a meat-free alternative, try our Seaweed Tagliatelle recipe, which combines traditional pasta and Sea Spaghetti with tomatoes, spinach and pumpkin seeds.

Add seaweed to a balanced recovery plate

Recovery food does not have to involve powders, complicated recipes or a perfectly measured meal.

A simple plate containing carbohydrates, protein and vegetables is a good place to start. Seaweed flakes can be sprinkled onto many of the foods you may already eat after training, including:

• Scrambled eggs or an omelette
• Rice and grain bowls
• Roasted or mashed potatoes
• Fish, chicken or tofu
• Soups and broths
• Pasta and noodles
• Beans, lentils and stews
• Salads and cooked vegetables

The Sea Salad Shaker contains a blend of Dulse, Ocean Greens and Nori flakes. It can be used on cooked or raw dishes and works especially well with eggs, potatoes, soups and salads.

For something cool and refreshing after a warm-weather workout, our Seaweed Raita or Tzatziki combines yoghurt, cucumber, herbs and seaweed flakes. Serve it with flatbread, roasted potatoes, grilled vegetables, falafel, chicken or fish to turn it into part of a more complete recovery meal.

Fibre, digestion and an active lifestyle

Seaweed contains dietary fibre, making it a useful addition to a varied diet.

Fibre supports normal digestive health, but timing is personal. Some runners can comfortably eat fibre-rich meals before training, while others prefer to save them until afterwards.

Start with small portions and see how your body responds. Introducing a large amount of seaweed for the first time shortly before a race or hard workout is unlikely to be a good idea.

Using a shaker can make portioning easier. A small sprinkle of Mixed Seaweed Flakes over a familiar meal is a simple way to begin without changing your entire diet.

What about Marine Collagen?

Collagen is not a replacement for the protein and carbohydrates needed in a balanced recovery meal, but some active people choose to include it as part of their wider routine.

Our Marine Collagen supplement combines marine collagen with Sugar Kelp, acerola berry, hyaluronic acid and vitamin C.

Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones, as well as helping protect cells from oxidative stress. Each recommended daily serving also contains iodine from seaweed.

The supplement contains fish, so it is not suitable for vegetarians or vegans. It should also be used alongside, rather than instead of, a varied diet.

Can seaweed improve endurance or speed up recovery?

Research into seaweed, algae and exercise is developing, but the results depend heavily on the species, format, serving size and type of exercise being studied.

At present, seaweed should not be described as a proven shortcut to faster running, a higher VO₂ max or reduced muscle damage.

Its more realistic value lies in the nutrients it can contribute to an active person’s diet. Seaweed can help bring variety to meals, provide naturally occurring minerals and make simple foods more satisfying through its deep, savoury umami flavour.

That may not sound as exciting as a miracle performance supplement, but good training is rarely built around miracles. It is built around consistent movement, adequate food, hydration, sleep and recovery.

Simple ways to add seaweed to an active diet

You do not need to completely change the way you eat. Start by adding seaweed to familiar meals:

Before training: Add Sea Spaghetti to pasta, sprinkle Sea Salad onto eggs or mix Ocean Greens into a fruit smoothie.

After training: Serve seaweed raita with potatoes and grilled protein, add flakes to a rice bowl or make Sea Spaghetti with crab and vegetables.

On rest days: Use Kelp in soups and stews, add Mixed Seaweed Flakes to roasted vegetables or sprinkle Sea Salad over salads and avocado toast.

When you are short on time: Keep one of our seaweed shakers near the hob or on the table and use it as you would any other seasoning.

A small ingredient that fits into the bigger picture

Seaweed will not replace a good training plan, a carbohydrate-rich pre-run meal or a balanced recovery plate.

What it offers is something quieter and more useful: an easy way to introduce a wider mix of naturally occurring nutrients and coastal flavour to the food you already enjoy.

For runners, walkers, swimmers, cyclists and anyone who spends their time moving, that makes seaweed a simple ingredient worth keeping close to hand.

Start with a sprinkle, add it to familiar meals and let it become part of your everyday routine — from the first bowl of porridge or eggs before a busy day to the warming plate of pasta waiting when you get home.
