What is sea moss?

Found in the Northern Atlantic coasts of America and Europe, sea moss (Chondrus crispus), also known as Irish moss, is a red seaweed rich in carrageenan. Carrageenan is a polysaccharide popularly used as a stabilizer or thickener in foods and cosmetics. Sea moss boasts a rich mineral profile, including iodine, calcium, magnesium, and iron. These minerals play pivotal roles in vital bodily functions like supporting thyroid health, fortifying bones, aiding muscle development, and facilitating oxygen transport.

Sea Moss has a storied history in Chinese medicine that dates back as far as 600 B.C. By 400 B.C., it had secured a place as a dietary staple throughout the British Isles. Notably, during the Great Famine in mid-19th century Ireland, sea moss emerged as a vital nutritional lifeline. Its popularity traveled with Irish immigrants as they settled in the United States and even went on to be seaweed farmers. Further fueling its rise to acclaim, sea moss gained prominence during World War II due to agar shortages, serving admirably as a substitute food thickener and emulsifier.

In contemporary wellness, sea moss retains its allure as a sought-after supplement used by health enthusiasts eager to support diverse health goals, prominently emphasizing weight management. Its versatility allows for effortless integration. It is commonly blended into revitalizing smoothies as sea moss gel or conveniently consumed in capsule form, catering to the preferences of wellness seekers worldwide.

What are the benefits of sea moss?

Sea moss is lauded as a promising aid for weight loss. Research highlights its potential to regulate appetite, influence fat metabolism, and nurture the friendly bacteria residing in the gut.

Low-calorie supplement

One of the key factors in sea moss’s weight loss support lies in its remarkably low-calorie content. With just five calories and 1 gram of carbs in a 2-tablespoon (10-gram) serving, it offers a practically negligible calorie load while imparting a sense of fullness, curbing excessive eating.

Fiber-rich superfood

At the heart of sea moss lies carrageenan, a bioactive compound with a significant impact. This compound, behaving akin to soluble fiber in the digestive tract, possesses a unique gelling ability. It forms a gel-like substance by absorbing water, thereby slowing down digestion. This process effectively regulates the movement of food through the digestive system, delaying stomach emptying and prolonging the feeling of satiety.

An alternative to weight loss medication

Animal studies further support the weight-regulating potential of sea moss. Evidence suggests that carrageenan, found abundantly in sea moss, contributes to reducing body fat through various mechanisms. It potentially lowers the absorption of dietary fat, curtails the formation of new fat cells, enhances the breakdown of stored fat, and even promotes the fat-burning effect of brown fat tissue.

Prebiotic benefits

Sea moss exhibits prebiotic properties by serving as a source of prebiotic fibers. These fibers act as nourishment for the beneficial bacteria in the gut, fostering a healthy gut microbiota. This symbiotic relationship contributes.

Thyroid support

Sea moss may support thyroid health by countering mineral deficiencies and alleviating inflammatory concerns. One of the standout benefits of sea moss lies in its capacity to regulate thyroid hormone production. In cases of underactive thyroid (hypothyroidism), sea moss serves as a natural treatment by stimulating hormone production, thereby aiding in restoring optimal thyroid function. Its role in boosting metabolism further contributes to its efficacy in supporting thyroid health. This marine wonder contains crucial thyroid hormone precursors like Di-Iodothyronine (DIT), Tri-iodothyronine (T3), and Thyroxin (T4). These precursors play pivotal roles in regulating thyroid function, ensuring the body’s hormone production operates at its best.

Holy grail skincare supplement

Sea moss is a skincare powerhouse. Packed with sulfur and a mix of calcium, magnesium, vitamins A and K, it nurtures and shields the skin from environmental stressors while maintaining a healthy microbiome. Its omega-3 fatty acids fill dietary gaps, calming and brightening the skin. Experts endorse sea moss for managing skin irritation, thanks to its rich nutrient profile. It’s also a breakout buster, regulating oil production and aiding skin healing. Beyond appearance, sea moss transforms overall skin health, making it more than just a beauty fix.

Side effects of sea moss

There is limited data on the side effects of sea moss. But carrageenan, found in sea moss, is an FDA-approved food additive with more solid research to offer. The typical iodine content in 3 to 4 grams of sea moss daily is considered safe. However, elevated iodine levels might cause symptoms such as:

  • Upset stomach
  • Nausea
  • Vomiting
  • Diarrhea

It’s also important to keep in mind that sea moss, as well as other ocean vegetation, can potentially hold toxic metals such as mercury, lead, and arsenic. Generally, this should not be an issue as long as you opt for reputable sources to mitigate potential metal contaminants.

How to incorporate sea moss into your life

When incorporating sea moss into your routine, moderation is key due to its high iodine content, which in excess could lead to adverse effects like goiter, thyroid issues, or even thyroid cancer. Additionally, the presence of potentially harmful metals like mercury or arsenic emphasizes the need for cautious consumption.

There’s no officially recommended dosage for sea moss, but research suggests that taking 0.14 ounces (4 grams) daily is generally safe. Frequent users advise a limit of 2 tablespoons (10 grams) per day to err on the side of caution.

Sea moss comes in various forms, including capsules, powders, dried, and gel forms, offering versatile options for consumption. These diverse formats allow for easy integration into different diets and preferences. Whether added to smoothies, taken as a supplement, or incorporated into recipes, sea moss offers flexibility in how you can enjoy its benefits.

NOBULL debuts new colorways for daily running shoe, Journey 2
Four new colorways just dropped for NOBULL's best-selling Journey 2 sneaker
NOBULL

NOBULL's Journey 2 sneaker is one of my favorite go-to sneakers for the gym (and my husband's, too). There's really something to be said about a sneaker that adds comfort, style, and durability to your gym outfit. I've been wearing these weekly for awhile now -- but now NOBULL has dropped even more fun colors in the same comfortable show. Just in time for the summer, NOBULL just dropped four new colorways in the Journey 2, including Classic White Cayenne, Classic White Signal Pink, Lunar Mineral White, and Blue Haze. These fun, vibrant colors add a touch of color to every gym outfit.

With a plate-less design, Journey 2 delivers a naturally smooth, cushioned ride. A multi-surface outsole provides reliable grip across varied terrain, while NOBULL’s unique stability chassis keeps your foot locked in through every stride and transition, so you can move freely wherever the miles take you. While I'm not usually one to make a statement with my athletic footwear, I have to admit I'm pretty excited about the drop of these new colors. The four new colors join the line up that still includes the classic colors, such as Classic White, Jet Black, and Molten.

Generational fitness: A father’s story for passing health to his children
David and Shaya Charvet talk fitness and working together as father and son
Adult, Female, Person

Father's Day is a holiday that is sometimes overlooked, sometimes celebrated, and sometimes divisive. There are those of us who have great relationships with our fathers, there are some who have strained relationships with our fathers, and then there are many of us who are in between. I was lucky enough to have the perfect father, split between three different men. My biological father taught me how to fail. Mostly, he taught me what not to be as a father by failing hard and often. There are lessons there. My step-father was the provider and the disciplinarian, something I didn't openly acknowledge even to myself until later in life. And my grandfather was the hero, the man I always looked up to and wanted to be. All three were vital to my upbringing and teaching me how to be a man, and some people have them in one person. Shaya Charvet grew up with a father who was first a rising star in Hollywood, who then stepped away at the height of his career to be a present father. He decided to be all three of the men I listed, and then taught lessons through fitness. David Charvet and his son have launched BUILD, a new kind of gym with a focus on all the things you would want out of staying in shape, with the background of a father and son learning together.

My dad brought me to the gym from a very young age. They always told me if you can take care of your body and be disciplined there, you can be disciplined in all other parts of life. - Shaya Charvet, Co-Founder BUILD
