How seaweed snacks can support your thyroid health

Seaweed probably isn’t the first thing that springs to mind when it comes to healthy eating. But this superfood vegetable straight from the ocean is amazing for supporting your thyroid health.

Roasted seaweed sheets are a natural source of iodine – a trace mineral that plays a huge role in hormonal balance and metabolism maintenance.

The connection between roasted seaweed snacks and your thyroid health

The thyroid is a small gland located at the base of your neck that helps to regulate your metabolism, energy levels and hormone production. To function properly, it needs iodine to develop essential hormones like thyroxine and triiodothyronine that work to keep your hormones perfectly balanced. This makes you feel well and energised and can also have a massive bearing on weight loss goals.

Seaweed is one of the richest sources of iodine, with 1-2 packs of MORiSH crispy seaweed thins containing about the whole daily recommended intake (150 micrograms = nutrient reference value). They’re a convenient snack to grab your iodine on-the-move.

Using iodine-packed seaweed thins for hormone balance

Hormonal balance isn’t focused on the thyroid alone. It’s a complex combination involving a range of hormones including oestrogen, cortisol, insulin and many more. But because the thyroid has the awesome power of influencing nearly every system in your body, it’s a great starting point to get those health goals in check.

Iodine-rich seaweed sheets fuel your body and can benefit you in lots of ways:

• Helping with weight management: Seaweed may support healthy weight management as part of a balanced diet and healthy lifestyle. The hormones in your thyroid can change the way your body uses energy, and any imbalance could slow down your metabolism. Iodine helps maintain a healthy metabolism by supporting thyroid hormone production, which influences how your body burns energy and stores fat.
• Increasing skin and hair health: Many people with thyroid issues experience dry skin and thinning hair. Addressing this using iodine-packed foods can help improve these symptoms over time.
• Improving mood: By supporting thyroid function, seaweed may indirectly help alleviate some menopause-related symptoms, like fatigue and mood swings.
• Supporting a healthy menstrual cycle: By supporting your thyroid, iodine may help keep hormone levels more balanced, which can lead to more regular and manageable periods.

Enjoy in moderation – a little goes a long way

Please note that seaweed is naturally rich in iodine, and despite its health benefits, moderation is key. Seaweed is a natural raw material, and the iodine content in raw laver is subject to natural variations depending on factors such as the harvest area (origin), season (harvest time), and environmental conditions.

For crispy seaweed sheets (nori-type snacks), the typical iodine content is roughly 20–25 µg per gram. Consequently, consuming 1–2 packs of crispy seaweed thins can provide close to the entire daily recommended intake of iodine (150 µg, the nutrient reference value).

A few snacks can go a long way, so it is important to avoid excessive iodine intake, which can lead to thyroid problems. According to the Scientific Advisory Committee on Nutrition (SAVN) a safe upper limit (UL) of approx. 1,000 µg/day is not expected to cause significant adverse effects in adults. However, individuals with chronic iodine deficiency may experience negative effects at lower levels, as their thyroid may have adapted to a low iodine supply.

Not all ocean vegetables are the same. Brown seaweeds such as wakame (c. 150–250 µg per gram) and kelp (c. 1,500–2,500 µg per gram) contain much higher concentrations of iodine and therefore carry a greater risk of excessive intake.

Seaweed sheets and metabolic support

The iodine that you obtain from MORiSH’s roasted seaweed sheets helps your body to produce thyroid hormones that increase your basal metabolic rate and stimulate calorie burning. This means that eating seaweed can also help you enjoy your other favourite treats without feeling guilty for the extra calories you’re consuming.

Seaweed also contains a range of antioxidants and anti-inflammatories that can help your body recover from other nasties and reduce swelling, bloating and inflammation while supporting your good gut bacteria.

Roasted seaweed sheets aren’t just a trendy snack – they’re an unsung hero when it comes to thyroid health with their natural source of iodine that improves your vitality. Not to mention, they offer a wealth of versatility when it comes to snacking. Eat them on the go right out of the packet, or crumbled over salads, soups or rice bowls; they add a fabulous crunch and some irresistible umami flavour to pretty much any dish.
