Additional Details

Supports Thyroid Health and Metabolism

Bladderwrack is one of the richest natural sources of iodine, an essential mineral required for thyroid hormone production. It has been traditionally used to support underactive thyroid (hypothyroidism) and conditions such as goitre. By enhancing thyroid function, it helps regulate metabolism, energy levels, and overall hormonal balance.

Aids in Weight Management

Due to its ability to support thyroid activity and metabolism, bladderwrack has been historically used in herbal weight loss formulations. The presence of fucoxanthin, a carotenoid found in seaweed, has been linked to increased fat metabolism and reduced fat accumulation.

Rich in Antioxidants and Anti-Inflammatory Compounds

Bladderwrack contains powerful antioxidants, including phlorotannins, fucoidans, and carotenoids, which help protect cells from oxidative stress and inflammation. These compounds contribute to overall well-being and may reduce the risk of chronic diseases such as heart disease and diabetes.

Supports Digestive Health

As a natural source of soluble fibre, bladderwrack aids digestion by promoting gut health and supporting a healthy microbiome. It may help alleviate bloating, constipation, and mild digestive discomfort. Some studies also suggest that the alginates in bladderwrack can support gut lining integrity and prevent acid reflux.

Promotes Skin Health and Wound Healing

Historically, bladderwrack has been used in topical preparations to soothe irritated skin, reduce signs of ageing, and promote wound healing. Its natural polysaccharides and minerals help hydrate the skin, making it a popular ingredient in anti-ageing and skincare products.

Supports Joint and Bone Health

Bladderwrack contains compounds that may help reduce joint inflammation and stiffness, making it beneficial for individuals with arthritis or other inflammatory conditions. The high mineral content, particularly calcium and magnesium, also contributes to bone strength.

Boosts Immune Function

With its rich supply of vitamins, minerals, and immune-boosting compounds, bladderwrack helps strengthen the body's defences against infections and environmental stressors.
