Good and effective product. 4 versus 5 stars only because ability to manage subscription and a 3 day reminder before renewal would make it perfect.

Written by the company
We started Seaonic because we were tired of synthetic supplements — powders filled with additives, sweeteners, and artificial flavorings that promised health but ignored how the body truly works. Our mission was simple: go back to nature and rediscover what the body actually needs to thrive. Seaonic brings us back to our oceanic origins, delivering over 78 ionic minerals and trace elements in their most natural, bioavailable form. Sourced from phytoplankton vortexes, the most nutrient-rich areas of the ocean, our marine plasma is cold-microfiltered using the AQP protocol to remove all contaminants while preserving the delicate balance of minerals that mirrors human plasma. Each sachet provides your cells with the perfect environment to function optimally — supporting energy, focus, hydration, recovery, and overall well-being. No additives. No flavorings. No preservatives. Just pure ocean nutrients, exactly as nature intended.

P.O.T.S. customer
My daughter is supposed to consume 10K milligrams of sodium a day due to her P.O.T.S.
So these little packets that don't require any mixing of anything are great for her to keep with her, for when she feels an episode coming.
When we had more deliveries than than we were using them the company was very easy & nice to adjust or cancel future shipments.

Do electrolytes help?
I'm not sure what this & similar products are so supposed to do for me. To that I'm not feeling any different but I hear electrolyte are good for me. I like that there is no sugar compared to other products as well as how convenient it is to take.

Thanks so much for your review and for giving Seaonic a try.
One thing that's often misunderstood is that electrolytes are marketed as performance enhancers, when their primary role is actually much more fundamental: correcting deficiencies and restoring your body's natural fluid and mineral balance.
Think of them like the foundation of a house. You shouldn't notice the foundation when everything is working properly—you only notice it when something goes wrong. At the cellular level, electrolytes simply allow your cells to function as they were designed to. That's why our focus isn't on creating an artificial "boost," but on providing clean, naturally balanced marine minerals without sugar, sweeteners, or unnecessary additives.
We really appreciate you sharing your experience and hope you continue enjoying Seaonic.

Thank you, J. We love that description—an easy, body-friendly way to support your mineral intake. We appreciate your support and are grateful to have you as part of the Seaonic community.
Hands down one of my favorite finds.
I did alot of research on the different electrolytes. For me I had several concerns, contamination of microplastics from the liner of the plastic packs. Transparency of testing and ingredients. The types of added flavors and sweetners. These electrolytes hands down for me are exactly what I was searching for, which is why I will continue to keep them as part of my routine.

After trying multiple different types of electrolytes for after working out. I don’t like the flavors of many of them, I don’t like the additives, and I don’t like household they are.
Seaonic meet my needs perfectly. I bring packets with me when I travel, and I use one in my water bottle when I work out. Very happy with them.

We completely agree that easier subscription management and renewal reminders are important, and it’s something we are actively working on improving. Thank you for supporting Seaonic and helping us make the experience better 🙏
Finally A brand that doesn’t make me sick!
I’ve only been on it a few days so far but already seems to be helping and I seem to be tolerating it well so far - this is the first of MANY electrolyte brands I’ve tried that I haven’t had a terrible reaction to. Even unflavored brands like Promix and LMNT have me horrible headaches and stomach aches. As far as I can tell so far I’ve not had issues with this one at all. I have POTS so finding an electrolyte that actually works is a HUGE deal to me especially as I work outside in the heat as a horse trainer. Keeping my fingers crossed I will keep tolerating it!
