Of every brand in this series, Trace is the one we feel closest to philosophically. Trace Minerals Research has been championing ionic trace minerals from the Great Salt Lake for decades, long before it was fashionable. ZeroLyte is their zero-sugar electrolyte stick, and it is a genuinely decent product.
So this comparison is not about exposing a flaw. It is about depth of commitment to a shared idea.

Where ZeroLyte is strong
Doses, honestly. At 1,000 mg of sodium it matches LMNT for heavy sweat sessions, and its 500 mg of potassium is more than almost anything in the category. If you sweat hard and your diet is low on fruits and vegetables, those numbers are worth something. Both products also share the same core insight: minerals should come as a broad natural spectrum, not two isolated salts.
Where the depth runs out
Magnesium first. ZeroLyte's 80 mg is better than most competitors, but it is still a top-up, not a foundation, as our audit in The Magnesium Gap shows. Tune Current's 220 mg from bisglycinate, malate, and ionic seawater forms covers 52% of your daily value in one stick, from forms chosen for absorption rather than cost.
Then everything else: ZeroLyte has no vitamin C, no vitamin D, no B vitamins, no antioxidant complex. It is an electrolyte product with good instincts. Current takes the same instincts and finishes the job as a complete nutritional foundation: multi-mineral, multi-vitamin, hydration, and super antioxidant support in one stick, including methylated B12 and folate, 500 mg of vitamin C, and the VitAlign complex.
The absorption detail people miss
Minerals do not work alone. Vitamin D needs magnesium to be activated. B6 supports magnesium transport into cells. Vitamin C supports chromium absorption. A mineral-only product asks you to source all those cofactors somewhere else. A foundation product packages them together on purpose.
Who should pick which
Pick Trace ZeroLyte if: you want a high-sodium, high-potassium, zero-sugar electrolyte for serious sweat replacement and already run a separate vitamin routine you trust.
Pick Tune Current if: you like the trace mineral philosophy and want the complete foundation built around it: more magnesium in better forms, plus the vitamins and antioxidants that act as its cofactors, in one daily stick.
FAQ
What is inland seawater concentrate?
A naturally occurring source of ionic trace minerals, harvested from mineral-dense inland seas. It supplies 75+ trace elements in Current, including zinc, selenium, copper, and boron.
How much magnesium does ZeroLyte have?
80 mg per stick, as magnesium citrate. Tune Current has 220 mg from three forms.
Are trace minerals actually necessary?
They act as cofactors in enzyme systems across the body. Modern diets and filtered water supply fewer of them than they once did, which is the case for supplementing a broad spectrum.
