Feedback from verified buyers on our official Tmall and Taobao flagship stores (translated from Chinese)
My son is an extremely picky eater — he refuses any supplement with a medicinal or artificial flavor. The Sun Stick tastes like naturally sweet orange juice, just the right balance of sweet and tangy, and now he grabs one himself after breakfast every day! After three-plus weeks, the most noticeable change is his digestion: he used to go two or three days between dry, difficult bowel movements, but now he is regular every morning. The cranberry Moon Stick half an hour before bed has clearly helped him sleep more soundly too. This has taken a huge weight off my mind!
🔍 Photos🔍 PhotosI did a lot of research before choosing a postbiotic for my sensitive twins. What won me over was the truly clean ingredient list — no artificial flavors, no preservatives, no sucrose — with patented strain numbers and the SC production license clearly printed. Both kids tend to get itchy noses and sneezing when the seasons change, and after nearly a month, the morning nose-rubbing has visibly decreased. Postbiotics don't need refrigeration, so I just toss stick packs in my mom-bag and tear one open on the go — so convenient. Already repurchased twice!
🔍 Photos🔍 PhotosThe Morning Boost, Evening Calm concept really resonates with moms! Daytime servings of EpiCor and vitamin C support immunity; nighttime GABA with magnesium and zinc supports deep sleep. My older daughter has trouble falling asleep and tosses and turns — now her Moon Stick before bed has become a fixed goodnight ritual. She loves the cranberry flavor and falls asleep much faster. The day-and-night pairing in one box is genuinely smart science. Highly recommended to all my friends!
🔍 PhotosI previously bought probiotic capsules from abroad that my daughter simply couldn't swallow — these individual powder sticks are so much friendlier. The powder dissolves in warm water with one gentle swirl, no clumping at all and not sticky in the throat. She used to have frequent bloating, bad breath and food stagnation; after about two weeks her tummy is soft and comfortable and her appetite has opened up remarkably. Made by the high-tech enterprise Weikai Haisi with patented strains — the quality is genuinely trustworthy.

Frequently Asked Questions
Postbiotics are preparations of inanimate microorganisms and/or their components that confer a health benefit on the host (ISAPP, 2021). They are obtained by inactivating probiotics while retaining the biological activity of cell structures and metabolites. Postbiotics are highly stable — heat-tolerant, acid-tolerant and shelf-stable — and require no refrigeration.
Probiotics are live microorganisms that must remain alive through storage; postbiotics are inactivated microorganisms and their components that do not need to be alive to function. The core advantages of postbiotics are higher stability (heat- and acid-tolerant, no refrigeration needed), a better safety profile, and efficacy that does not depend on surviving live bacteria.
