ENERGY, SLEEP & RECOVERY

Marine Magnesium

Marine Magnesium

Delivering 150mg per capsule of bioactive Magnesium to support restful sleep, improved energy, and effective muscle recovery.

Benefits

Strong Bones: Magnesium is known to help build and maintain bone density. Marine Magnesium also contains bone-friendly trace minerals, like calcium.

Happy Muscles: Magnesium plays a key role in building and relaxing muscles, which is why people often use Magnesium supplements to help post-exercise recovery.

Boundless Energy: Magnesium supports normal energy metabolism to keep you feeling vibrant and buoyant. 

Rest and Relaxation: Magnesium encourages the release of GABA, the neurotransmitter that regulates feelings of stress and anxiety, and supports deep, restorative sleep.

Highly Absorbable: Marine Magnesium is thought to have higher levels of bioavailability than other forms of Magnesium. So your body can soak up all that goodness like a sponge.

How To Use

We recommend taking 1-2 capsules a day, with food. If you're new to magnesium supplements, we recommend starting with 1 capsule to build tolerance before increasing to 2, as the supplement’s potency is often best introduced gradually.

Ingredients

Main ingredients: Each capsule contains 150mg of Marine Magnesium (Magnesium Hydroxide).

Capsule shell: Pullulan, maize starch (corn).

Got questions?
How should I take my Marine Magnesium?

We recommend taking 1-2 capsules a day with food. Some people like to take their Magnesium supplements at night to support relaxation and sleep. But remember, Magnesium has plenty of benefits for round-the-clock health—from energy, to post-workout recovery.

How do I get my recommended daily dose of Magnesium?

You can get Magnesium from a varied and balanced diet…but that’s not always possible, however good our intentions!

The recommended daily amount for Magnesium is:

  • 300mg a day for men (19-64 years)
  • 270mg a day for women (19 to 64 years)

Factors like age, pregnancy and health conditions can affect how much Magnesium you need.

We recommend taking 1-2 capsules of Marine Magnesium per day (each capsule contains 150mg of Magnesium), depending on your diet, lifestyle and health priorities. 

You can save 25% when you subscribe to a 30-day or 60-day supply—so you never miss your daily dose.

What’s the difference between Marine Magnesium and regular Magnesium?

Marine Magnesium is derived from seawater, while regular Magnesium comes from land-based sources, like rocks and soil. 

There are plenty of benefits to swapping your regular Magnesium supplement for Marine Magnesium: 

  • Better absorbability: Seawater is a rich source of bioactive Magnesium, which means your body can absorb it more easily.
  • Kinder to your gut: Because it’s more absorbable, bioactive Magnesium can benefit your gut health—whereas other forms of Magnesium are known to have laxative effects.
  • Bonus nutrients: Marine Magnesium gives you an extra boost of trace minerals and electrolytes. Bonus points for your health.
How long does it take to feel any benefits?

Magnesium is the small, but mighty mineral powering over 300 of your body’s biochemical reactions. So remember, a lot of its transformative effects take place below the surface.

But most NothingFishy customers tend to feel the difference in 1-2 months. Of course, each of us is unique—so this timeframe is based on averages and will vary from person to person.

What is the capsule made from?

The shell is made from pullulan and maize starch, which are both plant-based ingredients.

Wow! I am a raw vegan and started to read about DHA and how we need this vital nutrient for a number of functions. I have definitely noticed a difference and will continue to take these. I love that they are so pure as well as vegan and gluten free.
Diana H ionicons-v5-e
I love the quick service, the clear capsules, and the packaging: a beautiful glass bottle and a recyclable paper packet with the refill. This company really is environmentally minded, and so professional.
Meeshy ionicons-v5-e
These are nothing short of amazing. I follow a vegan diet and I am middle-aged with knee joint pain. I had previously taken flax seed and turmeric capsules then I tried these and the difference was noticeable in under 10 days. They have made the most enormous difference to me.
Kerry P ionicons-v5-e
Ticks all the boxes for me! They use totally recyclable packaging and provide a beautiful little glass bottle that I happily keep on show. The refill packages are also recyclable, so all promises are fulfilled.
Customer ionicons-v5-e
As a new vegan I've struggled to find supplements that are suitable for me. Imagine my joy when I found these!  Easy to swallow, no aftertaste and the complete reassurance that you're not putting any nasties into your body. The added bonus is the adorable bottle that I'm planning on keeping.
Sara D ionicons-v5-e
I’m delighted to have found these soft gels because they are made from algae rather than fish. No mercury or artificial flavours and they are easy to digest. Perfect for vegans and people who care about our planet like me.
David J ionicons-v5-e
The product arrived on time, is well packaged, the bottle looks nice, and the capsules are easy to swallow - no complaints at all! These tablets were recommended to me by my vegan friend who knows far more about healthy eating than I do!
Subscriber ionicons-v5-e
I absolutely love this product. The service is great and I like that I can pause and skip deliveries at any time easily. I've used NothingFishy for years and love everything about this company.
We created NothingFishy as an algae-based natural alternative to health supplements.
