Bladderwrack is best known for its use in treating thyroid disorders. In fact, it was the first source of iodine ever found, making it the go-to natural remedy for thyroid issues .Bladderwrack can help the thyroid in many ways, regardless of whether one’s thyroid is overactive or underactive. It has also been shown to treat problems that accompany a defective thyroid, such as weight gain, by acting as a weight loss supplement and pain reliever.

1. For Thyroid Health

Back during the 19th century in the days before modern medicine, bladderwrack was used as the original iodine source for medicinal purposes. Iodine is absolutely essential for the health of your thyroid and to ensure that your hormones and metabolism remain in healthy balance.

Because bladderwrack is such a rich source of iodine, it can be used to treat a variety of thyroid conditions which help control your metabolic and hormonal balance. Bladderwrack essentially works by stimulating the thyroid and allowing it to produce sufficient hormones.

2. For Women’s Health

When it comes to female health, bladderwrack offers plenty of potential. Iodine is necessary if the thyroid is to do its job properly and produce sufficient hormones. This is significant in terms of women’s health as a lack of hormones can hinder ovulation.

Poor thyroid function during pregnancy can have a detrimental effect on both the mother’s blood pressure and mental function of the unborn child.

Another function of iodine its use for treating fibrocystic breast disease , one of the leading causes of breast cancer. According to studies, bladderwrack has a similar function to soy in regulating a female’s sex organs making it a safe alternative to soy.

The same study linked above found that bladderwrack helped women with a history of short and light menstrual cycles. Those who took 1.4g of bladderwrack each day experienced considerably longer periods. Moreover, women who took bladderwrack produced less estrogen but increased their levels of progesterone.

Progesterone prepares a woman’s uterus lining for fertilization each month. Without sufficient amounts of the hormone, they are unable to conceive.

Note however that there are safety concerns regarding bladderwrack during pregnancy and pregnant women should only take it under medical supervision.

3. For Inflammatory Conditions

Bladderwrack has natural anti-inflammatory properties and it has been used down the years to treat various internal and external inflammatory conditions. For people with painful joints caused by conditions like gout or arthritis, bladderwrack may be just what they need to ease the pain and move more freely.

Bladderwrack can also help treat inflammatory skin problems and hemorrhoids in a safe and natural way. Depending on the type of inflammation you are trying to treat, bladderwrack can be taken internally or topically applied to the skin.

4. For Digestive Health

We are all aware of the importance of fiber as it relates to overall health and digestive health in particular. Unfortunately, that does not mean that we take heed and get enough of it. Bladderwrack is a great source of several types of healthy fiber including a fiber called alginic acid. Alginic acid has a very beneficial effect on digestion.

It can add bulk to the food passing through the bowels help relieve constipation. It also improves nutritional uptake making the food we eat more beneficial to our bodies. Bladderwrack can also help ease bloating and flatulence while it is also considered effective for painful stomach cramps and gastric ulcers.

5. For Heart Health

According to research, bladderwrack can help increase the levels of ‘good’ HDL cholesterol in the blood. By improving your cholesterol, this healthful seaweed can protect the heart from many killer diseases like atherosclerosis, heart attack, and stroke.

It may also have a knock-on positive effect on your blood pressure especially in people with hypertension which protects you from heart disease and means your cardiovascular system is put under less strain.

6. Fiber Content

Bladderwrack contains large amounts of a unique form of fiber called fucoidan. Fucoidan has been linked to a number of different health benefits including a reduction in cholesterol, reduced blood sugar and may even have anti-tumor effects.

Fucoidan helps to regulate the substance responsible for the reproduction of cells and their growth. In theory, fucoidan slows the growth of harmful cells meaning that it can hinder the proliferation of cancer.

7. For Obesity and Weight Control

As well as being high in fiber and possessing very few calories, bladderwrack can stimulate the metabolism making it a great way to lose weight. If your body is functioning at a higher level, it uses more energy and burns quickly through its fat reserves.

Some people say that bladderwrack helps you to feel sated and suppresses the appetite. This means that you will eat fewer calories throughout the day and in time….lose more weight.

Of course, there is no cure all for obesity and simply adding one foodstuff to the diet is unlikely to have significant effects unless you use it as part of an overall diet and exercise plan.

8. For Better Vision

As we have already mentioned, bladderwrack is a good source of beta carotene. This is an antioxidant pigment responsible for giving certain fruit and vegetables their rich colors. Beta carotene is known to improve eye health and vision by neutralizing the damaging effect of free radicals on the eyes. It helps to slow down the macular degeneration that comes with aging and can prevent cataracts from developing.

Taking bladderwrack supplements can reduce the appearance of age spots, wrinkles, and other unsightly skin blemishes. It also helps to tighten the skin and keep it more elastic even as you age.

Not only do antioxidants improve your appearance but they also help to combat the damage done to your insides from the harmful free radicals we can’t help but encounter every day. Natural antioxidants of the type found in bladderwrack and many other natural products can protect against disease and even reverse the damage done.

10. For Diabetes

According to a study published in 2011, bladderwrack may be useful for people with diabetes. The study set out to evaluate the effects of brown seaweed and bladderwrack on glucose and also insulin levels following a meal.

The double-blind study involved 23 patients of both sexes aged between 19 and 59. The researchers found that 500mg of bladderwrack in capsule form helped to decrease both insulin and glucose values. They also found that it increases insulin sensitivity in response to carbohydrate consumption and theoretically prevented their uptake.  Moreover, there were no adverse side effects associated with the use of the capsules.
