Full Ingredient List

A daily ritual for mind, body, and beauty, holi (mag) is a full-spectrum liquid magnesium supplement featuring six advanced, highly bioavailable forms—delivered in a delicious key lime pie flavor. Our proprietary, efficacious blend has never been sold before—this is magnesium, reinvented.

Magnesium is vital to over 300 metabolic functions, yet most of us are chronically deficient. Depleted soils, processed foods, chronic stress, and poor gut health make it nearly impossible to meet our needs through diet alone. And because the body requires optimal magnesium levels to properly restore vitamin D, even those supplementing D may not be absorbing it effectively without enough magnesium.

How to Use

Daily dose: Add 1 serving to water or your favorite beverage. Best taken in the evening before bed.

For maximum results: Take consistently every night. Most customers notice deeper sleep within 3–5 days.

Pair it: Combine with holi (mane) each morning for a complete daily ritual.

Results timeline: Most customers notice better sleep within 1 week, reduced tension and improved focus within 30 days.

A Quote from Our Founder
Jena Covello

Anytime I travel or fall off my routine and then come back to it, within a few nights I'm sleeping deeper and waking up actually rested. I take it every evening before bed and it's completely non-negotiable for me.
