The 3-in-1 Formula Your Arteries Have Been Waiting For
Most red yeast rice supplements only address cholesterol. That's one piece of a three-part problem.
Red Yeast Rice (800mg) contains monacolin K — the same natural compound found in statins — to support healthy LDL levels.
CoQ10 (60mg) fuels your heart at the cellular level. It's also the first nutrient statins deplete — which is why statin users feel exhausted.
Nattokinase (140mg / 2,000 FU) breaks down fibrin — the protein mesh that builds up inside your arteries and restricts blood flow.
Three ingredients. Three targets. One daily routine.
Just 2 capsules each morning and you're done.
What Happens Inside Your Arteries
Nobody talks about fibrin — but it's the reason circulation gets worse with age.
Fibrin is a sticky protein mesh that accumulates inside your blood vessels. It traps cholesterol, narrows your arteries, and forces your heart to work harder.
Nattokinase attacks it two ways:
✔ It directly decomposes fibrin on contact
✔ It activates your body's own plasminogen system to accelerate the breakdown
This is why users report warmer hands and feet, less leg heaviness, and steadier energy — often within the first few weeks.
Most red yeast rice supplements don't include nattokinase at all. This one does.

Not All Red Yeast Rice Is Created Equal
Most brands sell red yeast rice by itself — one ingredient, one target, and no testing for harmful contaminants.
Reviva is a complete 3-in-1 cardiovascular formula with CoQ10 for heart energy, nattokinase for circulation, and citrinin-free testing for safety.
One bottle replaces three. No stacks. No guesswork. No oversized pills.

Frequently Asked Questions
How do I take it for best results?
How do I take it for best results?
Take 2 capsules every morning with food and a full glass of water. Each capsule is 500mg (Size 0 — the smallest available for this formula), so they go down easy even if you're someone who typically struggles with supplements. Most customers take them with breakfast and don't think about it again for the rest of the day. Consistency is the most important factor — the active compounds in red yeast rice, CoQ10, and nattokinase build up in your system over time, so daily use is what drives real results. Skipping days or taking them inconsistently will slow down the benefits. Some customers ask about splitting the dose (one in the morning, one at night) — you can do that, but most people find it simpler to take both at once and build it into their morning routine so they never forget.
Is it safe to take alongside my statin or blood pressure medication?
Is it safe to take alongside my statin or blood pressure medication?
Many of our customers take this while working with their doctor to transition off statins, and others use it as a complementary addition to their current routine. That said, it's important to understand how the ingredients interact. Red yeast rice contains monacolin K, which works through the same pathway as statin drugs like atorvastatin and rosuvastatin — so taking both simultaneously could amplify the cholesterol-lowering effect beyond what your doctor has calibrated for you. CoQ10 is generally safe alongside most medications and is actually recommended by many cardiologists for statin users since statins deplete it. Nattokinase has mild blood-thinning properties, so if you're on anticoagulants like warfarin or blood thinners like aspirin therapy, this is especially important to discuss with your healthcare provider. Bottom line — if you're on any cardiovascular medication, have a quick conversation with your doctor before starting. Most are very familiar with these ingredients and can advise you on the best approach.
How is this different from taking a statin like atorvastatin?
How is this different from taking a statin like atorvastatin?
Statins work by forcing your liver to reduce cholesterol production through a single synthetic pathway. They're effective at lowering LDL numbers — no question about that. But they also deplete your body's natural CoQ10 stores in the process, which is why so many statin users experience muscle aches, chronic fatigue, brain fog, and that heavy "low-gear" feeling that never really goes away. Red yeast rice contains monacolin K, a naturally occurring compound that supports healthy LDL levels through the same biochemical mechanism — but without the synthetic load on your liver. This formula also adds back 60mg of CoQ10 to protect the heart energy that statins strip away, and includes 140mg of nattokinase (2,000 FU) to actively break down fibrin buildup in your arteries — something no statin on the market addresses. Statins lower cholesterol. This formula supports cholesterol, heart energy, and circulation together. That's the difference between treating one number and supporting your entire cardiovascular system.
When will I actually feel a difference?
When will I actually feel a difference?
Everyone's body is different, but here's what our customers typically report. The first thing most people notice is steadier energy and fewer afternoon crashes — usually within the first 2–3 weeks. That's the CoQ10 going to work at the cellular level, fueling your heart and reducing oxidative stress. Around weeks 3–5, circulation improvements start to show up as nattokinase breaks down fibrin in your blood vessels. Customers often describe warmer hands and feet, less heaviness in their legs, and deeper sleep. The cholesterol numbers take a bit longer — measurable LDL changes typically show up at your next blood panel around weeks 6–8, with the most significant shifts happening between months 2 and 3 of consistent daily use. That's because monacolin K needs time to build up and regulate your body's cholesterol metabolism. The key word is consistent — taking it every day is what makes the difference between modest improvement and real, noticeable change. And if you don't feel a meaningful difference within 60 days, you're fully covered by our money-back guarantee.
What's citrinin and why does it matter?
What's citrinin and why does it matter?
Citrinin is a toxic byproduct that forms naturally during the fermentation process used to produce red yeast rice. It's classified as a mycotoxin — in the same family as mold-derived contaminants — and has been linked to kidney damage, liver stress, and other health concerns in scientific literature. Here's the problem: independent testing has found citrinin contamination in a significant percentage of red yeast rice supplements sold on Amazon and in retail stores. Most brands either don't test for it at all, or don't disclose the results if they do. When you're taking a supplement every single day for months, even low levels of citrinin exposure can accumulate and create real health risks — which defeats the entire purpose of taking a heart health supplement in the first place. Every batch of Reviva Red Yeast Rice is independently tested and verified citrinin-free before it ever ships to a customer. This isn't something we do occasionally — it's every single batch, every single time. We believe if you're trusting a supplement with your cardiovascular health, the bare minimum is knowing it's not contaminated.
Why does this include CoQ10 and nattokinase instead of just red yeast rice?
Why does this include CoQ10 and nattokinase instead of just red yeast rice?
Because cholesterol is only one part of how your cardiovascular system breaks down with age. Red yeast rice addresses LDL levels through monacolin K — and it does that well. But your heart also needs cellular energy to pump efficiently, maintain rhythm, and recover from daily stress. That's what CoQ10 provides. It's a coenzyme that your body produces naturally, but production declines as you age — and drops even faster if you've ever taken a statin. At 60mg per serving, the CoQ10 in this formula supports the energy production your heart cells depend on. Then there's the circulation side. Even if your cholesterol numbers look good on paper, fibrin buildup inside your blood vessels can still restrict blood flow, increase blood pressure, and force your heart to work harder than it should. Nattokinase at 140mg (2,000 FU) directly breaks down that fibrin through two distinct pathways — both by decomposing it on contact and by activating your body's own plasminogen cleanup system. Taking red yeast rice alone is like changing your oil but never cleaning your engine or replacing the fuel filter. This formula addresses cholesterol, heart energy, and circulation together — because that's how your cardiovascular system actually works.
How is this different from other red yeast rice supplements on Amazon?
How is this different from other red yeast rice supplements on Amazon?
If you search "red yeast rice" on Amazon right now, you'll find hundreds of options — and the vast majority of them share the same three problems. First, they're single-ingredient products. Just red yeast rice, nothing else. No CoQ10 to support heart energy, no nattokinase for circulation. You'd have to buy those separately, which means managing three different bottles, three different brands, and three different quality standards. Second, most don't test for citrinin — the toxic byproduct that forms during red yeast rice fermentation. Some don't even mention it on their label or website. Third, most competitors use oversized Size 00 or 000 capsules that are difficult to swallow, especially for older adults who are the primary audience for this type of supplement. Reviva solves all three. You get a clinically dosed 3-in-1 formula (800mg red yeast rice, 60mg CoQ10, 140mg nattokinase) in an easy-to-swallow Size 0 capsule, with independent citrinin-free testing on every batch. One bottle replaces three, and you know exactly what's in it and what's not.
How long does one bottle last?
How long does one bottle last?
One bottle contains 120 capsules. At the recommended dose of 2 capsules per day, that's a full 60-day supply — two complete months per bottle. We designed it this way intentionally so that one bottle lines up exactly with our 60-day money-back guarantee. You can take the full bottle, use every capsule, and if you don't feel a meaningful difference by the end, we'll refund you. Most of our repeat customers settle into a rhythm of ordering every two months, and many buy the multi-bottle bundles to save on the per-bottle cost and make sure they never run out.
What if it doesn't work for me?
What if it doesn't work for me?
You're protected by our 60-day money-back guarantee — and that's not a marketing gimmick with fine print attached. Here's how it works: take the full bottle daily for up to 60 days. If your energy hasn't improved, if you don't notice a difference in how you feel day to day, if your bloodwork doesn't move in the right direction, or if you're simply not satisfied for any reason at all — email us at [your support email] and we'll refund your full purchase price. We don't require you to ship the bottle back, we don't charge restocking fees, and we don't make you fill out forms or jump through hoops. We built this guarantee because we genuinely believe in what this formula does, and because we'd rather have a happy customer who tried it risk-free than someone who never gave it a chance because they were worried about wasting money.
60-Day Money-Back Guarantee
We stand behind every bottle. If your cholesterol numbers don't improve, if you don't feel the difference in your energy and daily life, or if you're not fully satisfied for any reason — we'll give you a full refund. No fine print, no hoops to jump through. Just email us within 60 days and we'll take care of it. That's how confident we are in this formula.
