Built by Filipinos who use it daily
"From 80kg to a wellness brand."
Shinjiru was founded in 2023 by Kristina Dela Cruz Po (CEO) and her husband Reanne Niño Dy Po (COO) after their own science-backed transformations. They built the system they personally use every day — with Filipino doctors and nutritionists.

Hi po, nag-take ako ng GIS tapos sumunod sa 16:8. 1 month, 3.2kg less. Hindi ko sinama yung exercise kasi tamad ako, sa diet lang talaga. Worth it!
Para sa mga titos: 52 ako, may diabetes maintenance. Doktor ko clear na walang issue sa GIS. Less bloated, more energy after lunch. Salamat Shinjiru.
Hindi ako nag-eexpect na work. After 2 weeks, na-feel ko na yung bowel movement ko mas regular. Paayos lang siya. ✨ ang ganda magsalita ng tiyan ko ngayon HAHA
Real testimonials from our community.
Worth knowing
Mga bagay na hindi mo alam.
Samurai gut tonic
Centuries ago, barley was called silver oats sa Japan. Inumin ito ng samurai bilang gut tonic before battle. Tested by emperors, hindi lang ng influencers.
Psyllium = "broom ng tiyan"
Sa Ayurvedic medicine, psyllium husk ay tinatawag na isabgol — literal: "horse-ear leaf" kasi ganun ang hugis. 5,000-year-old wellness, packaged for 2026.
5,000 BC ang barley
Archaeologists found barley grains in Egyptian tombs from 5,000 BC. Pinaka-oldest na domesticated grain ng tao. Walang fad, walang TikTok trend — laging effective.
30 caps = 30 days = sakto
We sized the bottle exactly to the 30-day Shinjiru Challenge. Hindi sobra, hindi kulang. Run out the same day you finish the protocol. Math, hindi marketing.
Sino ang para dito?
If any of these sound like you.
"Bloated all day."
You eat. You feel heavy. Your pants feel tight by 3pm. Hindi naman lagi pero parang madalas na.
"Slow metabolism."
Same diet as before, but the weight is sticking. Your body's processing food slower than your appetite is asking for it.
"Hindi regular."
Constipation, irregular bowel, the feeling that things aren't moving the way they should. Common, fixable.
"Pinoy diet, pinoy gut."
High-rice, oily-ulam, low-fiber default. GIS is built around that reality — not around an imported wellness fantasy.
What it supports
Six things, one capsule.
Healthy bowel movement
Psyllium husk is a fiber bulking agent — moves things along the way they should.
Less bloating after meals
Supports digestive comfort, especially after high-rice or heavy ulam meals.
Metabolism support
Barley is a low-glycemic complex carb known to support steady energy and metabolic balance.
Fits a 16:8 routine
Take after lunch — within your eating window. No fasting disruption.
Compatible with maintenance meds
Generally safe alongside hypertension or diabetes maintenance — but consult your doctor first.
Plant-based formula
No synthetic fillers. Just Barley + Psyllium Husk in a vegetable capsule.
Bundles
The longer you stay, the more you save.
Most users feel a difference by week two — but the metabolism shift compounds over months.

GIS questions
Bago ka mag-order.
Pwede ba kahit may maintenance medication?
GIS is generally safe alongside hypertension or diabetes maintenance. Always consult your doctor before adding any supplement.
Kailangan ba talaga 1 capsule per day?
Yes. The bottle is 30 capsules, designed for one capsule daily for a full month. Doubling up doesn't accelerate results — it just empties the bottle faster.
When will I see a difference?
Most users feel less bloating by week 2. Metabolism shifts take longer — usually month 2 or 3 with consistent protocol. We don't promise specific results.
Pwede ba hindi sumunod sa 16:8?
Yes, but you'll see less of the metabolic benefit. The capsule works on its own; the 16:8 protocol amplifies it.
The protocol
One capsule. Post-lunch. That's it.
Eat your lunch
The capsule works best taken with food in the system. Don't take it on an empty stomach — barley fiber can feel heavy that way.
Take 1 capsule after lunch
One bottle = 30 capsules = exactly one month at one-per-day. Same time daily makes it habit.
Drink 2L of water through the day
Psyllium husk needs water to do its job. Skipping hydration defeats the point.
Pair with the Daily Golden Rules
8 hours sleep. 16:8 eating window. No 3-in-1 coffee or sugary drinks. We send the full guide free with your first order.
