Why It Works
Benefits
Night Diet Enzyme Kiwami delivers comprehensive digestive and metabolic support through carefully selected living enzymes and supportive ingredients.
Supports Healthy Digestion
Living enzymes help break down carbohydrates, proteins, and fats from your meals. The 720mg of active enzymes in Night Diet Enzyme Kiwami are produced using a proprietary non-heating method that preserves their natural activity, unlike many supplements that lose effectiveness during processing.
Proprietary Non-Heating ProcessPromotes Nighttime Metabolism
Your metabolism naturally slows during nighttime hours. The 7 diet support ingredients including turmeric (60mg), yeast peptide (130mg), and Gymnema Sylvestre work synergistically to support your body's natural metabolic processes when you eat later in the evening.
7 Active Support IngredientsSupports Gut Flora Balance
Contains 200 million spore-forming lactic acid bacteria that survive stomach acid to reach your intestines alive. Unlike regular probiotics, spore-forming bacteria remain dormant until they reach the gut, where they activate and support digestive health.
Live Probiotic DeliveryNatural Weight Management Support
Includes ingredients that may support healthy weight management: chitosan helps bind dietary fats, indigestible dextrin provides fiber for satiety, and coconut oil provides medium-chain triglycerides. These work alongside the enzymes to support your body after indulgent meals.

How It Works
Understanding the unique science behind Night Diet Enzyme Kiwami's living enzymes.
The Non-Heating Manufacturing Method
Shinya Enzyme developed the proprietary Koji Fungus Bio-Fermentation Activation Method that produces and processes enzymes without heat, preserving their natural activity.
This means the enzymes are truly "living" and can work in your body.

Age-Related Enzyme Decline
By age 50-60, enzyme activity may be less than half of what it was in your 20s. This age-related decline affects digestion, metabolism, and overall vitality.

Ingredient Research Highlights
DIGESTIVE ENZYMES
Digestive enzymes are proteins that help break down food into nutrients your body can absorb. The body produces enzymes naturally, but production decreases with age and stress. Supplemental enzymes can support digestion, particularly for those eating late or consuming rich foods.
Gastroenterological researchKOJI FUNGUS FERMENTATION
Aspergillus oryzae (koji) has been used in Japanese food production for over 1,000 years. Koji fermentation produces multiple enzyme types including amylase, protease, and lipase that support the breakdown of carbohydrates, proteins, and fats respectively.
Japanese fermentation scienceSPORE-FORMING PROBIOTICS
Unlike regular probiotics, spore-forming lactic acid bacteria form protective spores that survive stomach acid and heat. They remain dormant until reaching the intestines, where they germinate and become active, providing more reliable delivery than standard probiotics.
