Primary Ingredients

Magnesium from Organic Sea Lettuce Extract

Seaweed is an excellent source of magnesium, and sea lettuce has the highest natural magnesium content of all known seaweeds. We extract our organic sea lettuce using purified seawater, which yields a highly soluble form of magnesium coupled with natural carotenoids, B vitamins, and chlorophyll. This kind of multi-form magnesium complex ensures optimal absorption and bioavailability.

Magnesium from Purified Seawater Concentrate

Seawater is not only a fantastic source of soluble magnesium, it also provides a matrix of essential trace minerals like calcium, potassium, and selenium. Our mineral-rich seawater is sourced from the pristine Irish Sea and yields highly bioavailable magnesium salt that is gentle on your stomach and works in harmony with your body.

Magnesium from Organically Bound Spirulina

Minerals like magnesium naturally seek attachments to organic, living compounds – like the abundant proteins in spirulina. By binding magnesium to an organic whole food like spirulina, it is better tolerated by your digestive tract, more easily absorbed, and delivers additional plant-based compounds like beta carotene for enhanced bioavailability.

Certified Organic Irish Sea Moss

Irish sea moss contains a full spectrum of minerals – like iodine, calcium, potassium, and sodium – which can help your body better utilize supplemental magnesium through electrolyte balance and mineral transport. Our certified organic Irish sea moss is sustainably wild harvested from the Gulf of Maine, then sun-dried and gently milled to preserve its precious mineral matrix.

Certified Organic Atlantic Wakame

Nestled in the leaves of Atlantic wakame is an array of phytonutrients, including chlorophyll and potent antioxidants, that work alongside magnesium to promote healthy energy metabolism and cellular vitality. Our certified organic wakame is sustainably cultivated in the open waters of Maine. The seaweed is grown on low-impact longlines, then gently harvested, sun-dried, and slow-milled to maintain peak nutrient density.

Magnesium Shaped by the Sea

Shaped by the steady rhythms of the ocean, our full-spectrum Vital Ocean Magnesium™ provides multiple forms of marine-born magnesium plus trace minerals to reinstate deep, whole-body balance.

Full-Spectrum Magnesium

Unlike synthetic, single-benefit magnesium products saturating the market, Vital Ocean Magnesium™ supports your whole-body – from restorative sleep, to a calm stress response and relaxed muscles. Made from organic seaweed, algae, and seawater, it delivers multiple sources of body-friendly magnesium for natural, full-spectrum support.

Marine Trace Minerals

As the most primordial force on the planet, the ocean is an exceptional source of the elemental minerals that shape our world and our bodies, like calcium, zinc, selenium, and iodine. Made from both ocean-grown seaweeds and mineralized seawater, Vital Ocean Magnesium™ delivers these minerals and more for optimal absorption, electrolyte balance, and cellular health.

Sustainably-Grown Seaweed

Seaweed is more than a superfood; it’s a cornerstone of ocean health, restoring ecosystems, absorbing carbon, and nurturing marine life. In Vital Ocean Magnesium™, we use a combination of tank-grown, ocean-cultivated, and wild-harvested seaweeds to ensure each ocean-born ingredient is grown in its ideal conditions – while also safeguarding the ecosystems seaweed helps sustain.

Intentionally Made For Impact

Based in Moab, UT, The Synergy Company is a Certified B Corp committed to pure, organic ingredients and sustainable practices that help pass on the gift of health to people, places, and the planet. All products are manufactured in our independently-owned USA facility with US and imported ingredients.

Amazing - magnesium deficiency supplement

"This magnesium supplement is Amazing (as with other PS products). The first night I took it, I noticed a BOOST in my energy levels the next morning/day. On the 2nd day, I noticed my energy level dropping in the afternoon/evening, so I took another dose and boom - I noticed my body and mood chilling out, stress and tiredness level going down. I just researched and found out that my ethnic background tends to lead toward magnesium deficiency. So glad I found & tried this!! Naturally (as with other PS products), my sugar cravings dropped, too. On the 3rd day (today), I stopped & tried taking the Bone Renewal pills, as they contain magnesium also -- I guess it worked, but I feel this algae magnesium supplement is more potent. Definitely recomment to try! Thank you PS for all of your amazing products. !"
