Sea moss and elderberry are two of the most talked-about cold-season supplements right now. They're not doing the same job, and the research behind each one looks very different. Here's what you're actually getting.

Do sea moss and elderberry both support immunity?
Not in the same way. In the Sea Moss Immunity Duo, the immune-specific nutrients are the vitamin C and zinc in our Elderberry Gummies with Vitamin C & Zinc, both of which contribute to normal immune function.[2][3] Elderberry itself has some small studies behind it for cold and flu symptoms.[4] Sea moss is better thought of as a mineral-rich seaweed food, with naturally occurring iodine and potassium.[1]
Caveat: Human research on sea moss is still limited, so we don't make immune claims for it. It's in this duo as a daily mineral habit, not as the immune piece.

Why these two are bundled together
A lot of people already reach for elderberry once the weather turns, and sea moss has become a daily ritual for many of the same people. Bundling them is about convenience: one routine that covers the immune-support nutrients you'd look for in the colder months (vitamin C and zinc, with elderberry) plus the sea moss habit you may already have.
For the deeper breakdown on sea moss on its own, see Sea Moss Benefits: What the Research Actually Shows. This article focuses on what's in the bundle and how to use it.
What elderberry, vitamin C and zinc actually do
Vitamin C and zinc are both well established as nutrients your immune system needs to work normally.[2][3] A Cochrane review found that regular vitamin C supplementation didn't prevent colds in the general population, but it was linked to slightly shorter colds.[5]
Elderberry has a smaller evidence base. A few small studies suggest it may help ease flu-like symptoms, but the research isn't strong enough to say for sure.[4] Our Elderberry Gummies with Vitamin C & Zinc pair 150mg of elderberry with vitamin C and zinc, so you're not relying on elderberry alone.
What sea moss actually does
Sea moss is a red seaweed that's been eaten as a food for generations. It naturally contains minerals like iodine and potassium, and our Sea Moss Gummies pair it with bladderwrack (a brown seaweed) and burdock root.[6] Most of the research on sea moss compounds comes from lab and animal studies, so we keep the claims simple: it's an easy way to add a mineral-rich seaweed to your day, in a berry gummy instead of a jar of gel.
The one thing to know is iodine. Seaweed iodine content varies, and too much iodine can affect thyroid function.[1] That's why we third-party test our sea moss and list the iodine note on every product.
The honest summary
- Vitamin C and zinc have the clearest evidence here: both contribute to normal immune function.[2][3]
- Elderberry has promising but limited research for cold and flu symptoms.[4]
- Sea moss is a mineral-rich food, not an immune supplement. If you have a thyroid condition, check with your doctor first.[1]
OUR OPTION
The Sea Moss Immunity Duo pairs a full-size bottle of Sea Moss Gummies (60ct, vegan) with Elderberry Gummies with Vitamin C & Zinc (60ct, vegan) for less than buying the two separately.
STAY CONSISTENT
Two gummies only help if you actually take them. Our 7-Day Pill Organizer keeps a week of both sorted so it's harder to skip a day. See the full Vita Globe Merch line →
Frequently Asked Questions
Can I take sea moss and elderberry together every day?
Most people can. Follow the suggested use on each label and take the sea moss gummies with a meal. Check with your doctor first if you're pregnant, nursing, managing a medical condition or taking prescription medication.
Is the iodine in sea moss a concern?
Sea moss and bladderwrack naturally contain iodine, and seaweed iodine levels can vary a lot. Adults need 150mcg a day, and the upper limit is 1,100mcg.[1] If you have a thyroid condition, take thyroid medication, or are pregnant or nursing, talk to your doctor before adding sea moss.

There isn't good evidence that elderberry prevents colds or the flu. A few small studies suggest it may help with symptoms, but more research is needed.[4]
