Wellness, guided by your own data.
MOJO Labs is the supplement brand of 6Letters Co., Ltd., a digital health company in Seongnam, South Korea, building wearable-based tools that help people understand their own body signals.
6Letters was founded in 2025 to make wellness patterns visible using Apple Watch signals such as HRV, resting heart rate and sleep. MOJO Labs pairs that insight with simple, well-made supplements.
Our formulas are manufactured in the USA with clear, complete ingredient labels. We show what is inside every product.
Honest wellness claims, no hype. 30-day returns on unopened products, and a free month of the MOJO KING app ($26.99 value) with every order.
