Here's What a Nutritionist Says

Sea moss is sold in several forms, including dried, ground, or in pills or droppers. Sea moss products sold as a dietary supplements aren’t regulated in the same way as prescription drugs. They do not have to be proven to be effective or safe before they are marketed. And there is largely no way of knowing if what is stated on the label is precisely what’s in the product.

This isn’t to say that supplements shouldn’t be used. I believe many are beneficial, but it’s important to use caution, and to take supplements with the guidance of your doctor or a dietitian who can recommend the right form, dose, frequency, and length of use, or identify any potential precautions to be aware of.

Bottom line: Adding some sea moss to an occasional smoothie or a plant-based pudding (note: sea moss has a natural thickening property) is probably fine, and may offer some nutritional advantages. But don’t overdo it, count on it as a cure all, or blindly accept all of the claims about its benefits, particularly from those profiting from its sale. Most importantly, seek out an independent expert before you incorporate any supplements into your daily or regular routine.
