For a heart that keeps up with you
Developed from the Japanese cold-aging protocol, tested by clinical researchers who don't cut corners
Non-GMO, gluten-free, GMP-certified, and third-party tested for SAC purity and ubiquinol potency
Specifically formulated to support arterial flexibility and cellular heart energy
From ZENI, the brand engineered for synchronized cardiovascular health
Steady, all-day stamina that fits any routine
ZENI is built for sustainable cardiovascular vitality, not overnight miracles. Take two softgels a day and give your body time to respond.
Active nutrients, like standardized S-allyl cysteine and bioavailable Ubiquinol, compound over 4–8 weeks of consistent use to relax arterial resistance and recharge cellular ATP. The most effective supplement is the one you actually look forward to taking, so we engineered it 100% odorless with zero stomach burn—a frictionless two-softgel morning ritual and nothing more.
ZENI IS THOUGHTFULLY CRAFTED TO SUPPORT ARTERIAL ELASTICITY, CELLULAR ENERGY, AND SUSTAINED STAMINA.
Targeted actives at clinically informed doses
Vascular Defense
Vascular Defense
1. Aged Garlic Extract (AGE) — 600 mg
Standardized for bioactive S-Allyl Cysteine (SAC) via traditional Japanese cold-aging fermentation to relax rigid arterial walls with zero odor or gastric burn.
2. Vitamin K2 (as MK-7) — 180 mcg
Guides calcium directly toward bone tissue and away from delicate arterial lining to preserve healthy microvascular elasticity.
Cellular Energy
Cellular Energy
1. Coenzyme Q10 (as Active Ubiquinol) — 100 mg
Delivers pre-converted, ready-to-use fuel directly to cardiac mitochondria, generating cellular ATP without forcing your liver to convert raw ubiquinone.
2. Magnesium Bisglycinate Chelate — 120 mg
A gentle, highly bioavailable chelate that supports steady heart muscle contraction rhythms and relaxes smooth vascular muscle tissue.

Botanical Co-Factors
1. Japanese Hawthorn Berry Extract (Crataegus oxyacantha) — 150 mg
Rich in cardiovascular flavonoids and proanthocyanidins to support smooth peripheral microcirculation and clean capillary blood flow.
2. Standardized Black Pepper Extract (BioPerine®) — 5 mg
Enhances gastrointestinal absorption, ensuring maximal lipid-soluble uptake of both Ubiquinol and aged garlic metabolites into the bloodstream.
Another Barrier To Better Heart Health, Gone.
ZENI has spent years breaking down the barriers to frictionless cardiovascular protection. The Japanese Heart Protocol is one more way ZENI clears the path to lasting stamina, this time from the inside out.
Your blood vessels and your heart muscle aren't separate systems — they run on the same circulation, the same endothelial defenses, the same cellular fuel. ZENI was built to support both, with a formula that hides nothing: every dose, every standardization, right on the label.
Frequently Asked Questions
How often should I take ZENI?
How often should I take ZENI?
Take 2 softgels once daily, preferably with a morning meal or a glass of water. Because CoQ10 Ubiquinol and aged garlic actives are fat-soluble, taking them with breakfast or healthy dietary fats optimizes daily absorption.
How many softgels come in a pouch?
How many softgels come in a pouch?
Each pouch contains 60 easy-to-swallow liquid amber softgels, providing a full 30-day supply at the clinically studied daily dose (2 softgels per day).
What makes your formula different from other heart supplements?
What makes your formula different from other heart supplements?
Most products take an isolated approach—either giving you raw garlic that burns your stomach and causes foul odor, or generic drugstore CoQ10 (ubiquinone) that aging bodies struggle to convert. ZENI uses the "Pump & Pipe" synergy: authentic Japanese Aged Garlic standardized for odorless S-allyl cysteine (SAC) to relax arterial pipes, paired with pre-converted active Ubiquinol to fuel the cardiac pump.
Will I get garlic breath or stomach upset?
Will I get garlic breath or stomach upset?
No. ZENI utilizes an authentic Japanese cold-aging fermentation process that completely neutralizes volatile, harsh allicin into stable, water-soluble S-allyl cysteine (SAC). It is 100% odorless, gentle on the gut, and causes zero sulfur burps, heartburn, or skin odor.
How long until I notice a difference?
How long until I notice a difference?
Many customers report feeling lighter on their feet, experiencing warmer extremities, and noticing cleaner physical stamina within 2 to 4 weeks. The deeper benefits—such as microvascular elasticity and replenished cellular ATP—compound with consistent daily use over 8 to 12 weeks.
