Sea Moss Benefits for Pregnant Women

Sea moss contains numerous pregnancy-supporting nutrients and is comparable to prenatal vitamins in many ways. As a natural source of minerals, vitamins, folic acid, and iodine, it provides great health benefits for pregnant women and their babies.

Pregnancy vitamins & minerals

Chondrus Crispus contains 92 of the 102 minerals our body needs to function, including the pregnancy kit: calcium, iron, zinc, iodine, folate, magnesium, phosphorus, potassium, vitamin C, thiamine, riboflavin, niacin, vitamin E, A, K, and others. 

Taking sea moss also helps boost the immune system and energy levels which is quite appreciated when carrying a baby!

A natural source of folic acid 

What pregnant women haven’t heard about folic acid? It’s probably the #1 supplement to have during pregnancy

Women are advised to take 400 mcg of folic acid every day before pregnancy and until they’re 12 weeks pregnant. It helps get pregnant in the first place and prevent birth defects.

Sea moss is packed with folate, the natural form of folic acid. ¼ cup of sea moss contains an average of 36 mcg of folate, which is quite a lot for natural foods.

Complement with prenatal vitamins or other natural sources of folic acid such as dark green leafy vegetables, beans, peanuts, fresh fruits, whole grains, liver, seafood, and others.

It increases iodine intake

Irish moss is also known to be one of the greatest natural sources of iodine.Iodine deficiency during pregnancy may cause serious neurodevelopmental problems including cognitive or motor issues, and even cretinism.

Because of their increased thyroid hormone production, renal iodine losses, and transfer of iodine to the fetus, all pregnant women need iodine supplementation. While the daily recommendations are set at 150 mcg for adults, it’s increased to 250 mcg for pregnant women and 290 mcg for breastfeeding mothers[1].

One study found that a serving of sea moss (2 tbsp) contains an average of 47 mcg of iodine[2]That's 19% of the recommended 250 mcg for pregnant women and 16% of the 290 mcg for breastfeeding mothers.

Is Sea Moss Safe During Pregnancy?

Irish moss is a safe product to consume including during pregnancy. But like with any potent food and supplement, while taking a reasonable amount every day can do wonders to your health and the baby's development, too much of it could put both your lives at risk. The main risks here come from exposure to high levels of iodine and heavy metals.

Excess of iodine 

As said above, iodine is absolutely essential for the fetus's development and all women should increase their iodine intake during pregnancy. However, too much iodine could be harmful to both the mother and the fetus. 

Iodine poisoning is extremely rare. According to the National Institute of Health, the safe daily upper limit for adults is set at 1,100 mcg. That includes all sources of iodine (sea moss, but also other foods, beverages, and supplements). Above 1,1 mcg per day[3], iodine supplements may cause health problems if not taken under medical supervision (in case of iodine deficiency for example).

To reach dangerous levels of iodine, one would need to ingest more than 20 times the daily recommended dosage of sea moss. While it seems very unlikely, make sure to keep track of how much sea moss you’re eating while pregnant. 

Heavy metals

Wildcrafted sea moss may also contain heavy metals found in polluted ocean waters. Pregnant women are advised to pay special attention to levels of lead, mercury, cadmium, or arsenic in their foods.

Exposure to high levels of heavy metals can increase the risks of miscarriage, stillbirth, and birth defects, as well as affect the baby’s brain development. 

High mercury levels are often found in seafood products, especially in big predator fishes like sharks, swordfish, king mackerel, or tilefish. Seaweeds like Irish moss can also absorb heavy metals. 

During pregnancy, make sure you’re only eating high-quality sea moss. All products sold at Organics Nature are tested by a third-party laboratory and guaranteed pregnancy-safe with the lowest levels of heavy metals.

How to take sea moss while pregnant?

While pregnant, you can take sea moss in the same way anyone would take it. Sea moss is available in a wide range of products, including sea moss gel, capsules, raw dehydrated alga, or powder. 

Make sure not to exceed the daily recommended amount of 2 tbsp of gel, 2 capsules, 2000 mg of power, or 2-4 tbsp of raw dehydrated sea moss a day.
