I've been so sick since 6 months ago my body and knee is been hurting so much was admitted to the emergency room 6 times with symptoms no one knew what I had doctors could not figure what I had. So I can give this awesome product a 10 in my world thank you!

Absolutely Amazing - Life Changing

I am currently pregnant and was told my my ferritin levels were low, around a 10 when they should be around 30. They offered me iron fusions, but I was already taking in 300% the daily value of iron, and was still being told I was deficient. It didn't seem right. I refused the fusions, to conduct a little more research on my own. I learned that I may not be absorbing the iron I am intaking, because I am lacking in minerals like copper, magnesium, vitamin A, ETC.I started taking these pills and within 1 week I had my energy back, my mood was better, I was able to work out regularly again, my hair started getting thicker, and my teeth got whiter. Most importantly I was having heart palpitations for years, not knowing why. Now I am thinking it was due to anemia. Since taking these pills I have not had 1 palpitation! I feel so amazing. I am 33 weeks pregnant and have more energy than I did my entire pregnancy. Just give it a try!!!!

This product was great got my weak gums and other benefits that I need to.

I was given a recommendation by an old friend on the on the use of beef liver supplements to aid in enhancing the strength of my gums. I noticed my gums to be bleeding every time I brush my teeth. I told my friend about it and that started my relationship with beef liver supplements. It has indeed done its job because in just less then a week use, My gums no longer bleed when I brush my teeth. Being highly satisfied with the effects it has brought on my teeth and gums, I have decided to make this beef liver supplement a part of my daily regimen. I have been using this supplement for almost 2 weeks already and it was only then that I was able to connect things together. I was so preoccupied and focused on my teeth and gums that I had noticed right away but ever since I started taking the supplement I had the increase in entry level that I havent felt before period normally, a days work would leave me tired exhausted. Now, I cant feel that there is still energy left in me to go on. As the days passed, I learned to maximize the energy in me and had made me more productive as I am able to accomplish note things at a faster rate. The best thing of it all is that now, there is still some left for me to enjoy after a hard day's work. A little quality time for me to watch TV, listen to music or read a book is all I need to make my day complete and now I can do it courtesy of beef liver supplements

My iron levels are at a healthy level again! My skn and hair feel thicker too.

My doctor recommended me to eat more beef/chicken liver to build up the nutrients needed for higher iron levels. He said my iron deficiency is quite high. I knew I needed to make a change other wise I will risk being sick again, my body won't be strong enough to fight off pneumonia or other illnesses. I scoured Amazon for all the different beef liver supplements and came across this one. The reviews all check out, and this brand seems to be credible as they are third-party certified. I also notice the beef comes from New Zealand, grass fed and doesn't contain any harmful chemicals, no antibiotics or hormones. Fast forward almost 41 days, and I notice my skin is silkier, smoother than before. I didn't have as much dead skin exfoliating when I use the sauna, and my skin seems to be more vibrant. Am I looking younger I asked? The biggest thing I noticed was the wrinkles in my hand were not as noticeable, I am actually looking younger I told my self. My friend of 6 years came to visit from out of town and instantly said I had more of a glow when I first saw her. Anyways, this has convinced me that taking this product can keep my iron reserves at a healthy level and will help to prevent me from being sick in the future. My last col/flu was before I started taking this product. I have not gotten one since. This deserves my 5 stars!

Crazy man!!!

I took the plunge and ordered them, My fingernails are getting thicker, They don't splinter and break like they used to. I can go up my stairs better, and I can actually get out of my bed by just putting my feet ON the floor and standing up now and don't feel like I'm going to fall over like before....and my brain fog is lifting! Now we will see if my hair gets thicker and stronger............

6 Nutrients Your Liver Needs and a Clean Diet Rarely Gives It

Even a clean diet is low in most of these. Beef liver has all six in one food, and each one has a job in how your liver handles fat and toxins.

🩸

Heme Iron

Most bioavailable form on earth

Iron carries oxygen to the muscles you use to walk, lift and keep going after work. Iron from beef liver is absorbed 2–3x more efficiently than iron from plants.

✓ Up to 300% better absorption than plant iron
⚡

Vitamin B12 (Cobalamin)

700% more than muscle meat

B12 is needed for every reaction that turns food into energy. When it runs low, you get the 3 PM crash and reach for another coffee. Beef liver is the richest food source by far.

✓ Natural methylcobalamin form — not synthetic
👁️

Vitamin A (Retinol)

Pre-formed — not beta-carotene

True vitamin A (retinol) comes only from animal foods. Your liver uses it in the first stage of clearing toxins and to protect its own cells. The beta-carotene in carrots is a poor substitute most people can't convert well.

✓ Directly usable — no conversion required
🔮

Copper

Critical trace mineral

Copper helps your liver make bile, the fluid that breaks down the fat you eat. Without enough of it, fatty meals leave you bloated and heavy. Low copper is increasingly common in modern diets.

✓ Supports bile production and fat digestion
🧬

Folate (Vitamin B9)

5x more than kale per serving

Your liver uses folate to repair its own cells and for methylation, one of its main ways of clearing toxins. Liver folate is the active, natural form, not the synthetic folic acid in most pills.

✓ Active natural form — superior to synthetic folic acid
🛡️

CoQ10 & Glutathione Precursors

The "master antioxidant" fuel

Glutathione is the main molecule your liver uses to clear toxins. You can't supplement it directly; your liver has to make it. Beef liver gives it the raw materials. A detox tea does not.

✓ Fuels your liver's own detox, no tea required

Marcus Lost 14 Pounds. Javier's Liver Enzymes Came Back Normal.

Marcus couldn't stand the taste of liver. Javier's doctor was watching his liver enzymes. Here's what happened when they, and other customers, stayed consistent.

★★★★★

I was terrified to try actual liver — I despise the taste. But these capsules? Zero taste, zero smell, just results. My bloating is gone. My energy is back. I've lost 14 pounds since starting — not because of some crazy diet, but because my liver is finally processing fat the way it's supposed to.

I had non-alcoholic fatty liver disease and my doctor put me on a monitoring protocol. I started these capsules alongside a diet change. At my 90-day follow-up, my liver enzyme levels dropped from elevated to completely normal. My doctor literally said "whatever you're doing, keep doing it."

7 Signs Your Liver Is Crying Out for Help

Your liver does over 500 jobs a day, and handling fat is one of them. When it's overloaded, these are the signs men notice first, starting at the belt.

🚨 Sign 1: The Belly Grows While You Eat Less

You cut the bread, you walk 10,000 steps, and the belt stays on the last notch. Non-alcoholic fatty liver now affects 1 in 3 adults in the US, drinkers or not. Most doctors don't catch it until it's advanced, because the early signs look like "just feeling tired."

😣

2. Bloated and Heavy After Meals

Your liver makes the bile that breaks down fat. When it can't keep up, you get bloating, gas and that heavy, uncomfortable feeling after dinner.

😴

3. Tired by 3 PM After a Full Night's Sleep

You sleep 7–8 hours, still wake up tired, and need another coffee by mid-afternoon. A sluggish liver can't turn nutrients into usable energy.

🩺

4. A Doctor Mentions "Liver Enzymes"

The letter says "elevated liver enzymes." You read it twice in the car and don't tell anyone. It's one of the few signs that shows up on paper.

👕

5. The Shirt Stays On at the Beach

Your daughter drums on your belly and everyone laughs. You laugh too, then pull your shirt down and leave it on all day.

🌑

6. Dull or Yellow-Tinged Skin

Your skin shows what your liver is dealing with. When it's overloaded, skin looks dull and the whites of your eyes can turn slightly yellow.

🍵

7. Detox Teas Did Nothing

They sent you to the bathroom and changed nothing else. Your liver needs food nutrients, not a tea: real vitamin A, copper and B12 to rebuild what it uses every day.

As Featured In

🔬 How It Works: Food for Your Liver, Not a Tea

1

The Problem: Your Liver Is Short on Nutrients

Eating clean cuts calories. It doesn't add the vitamin A, copper and B12 your liver uses to process fat and clear toxins.

2

Why the Teas Failed: Nothing Went In

Detox teas and cleanses push things out of your body. They don't put anything in. Your liver can't rebuild with nothing to work with.

3

The Fix: Nutrients Your Body Can Use Right Away

Beef liver nutrients come already in the form your body uses (vitamin A as retinol, B12, heme iron), so you absorb and use nearly all of it. Synthetic vitamins can't match that.

4

The Result: Your Liver Handles Fat Again

With bile and detox enzymes fueled, your liver processes fat the way it was designed to. Bloating eases first. The belt comes after.

You Know Liver Is Good for You. You Just Can't Eat It.

Pound for pound, beef liver has more essential nutrients per calorie than any other food on earth, including spinach, blueberries, salmon and eggs. That's why it's often called nature's multivitamin.

Maybe you tried liver and onions once. One bite, and the dog got the plate. Lonvera's capsules give you the full nutrition of fresh grass-fed liver with zero taste, zero smell and nothing to cook.

Each batch is sourced from pasture-raised, grass-fed and grass-finished cattle, then freeze-dried at low temperature to preserve the full enzyme and nutrient profile — exactly as nature packaged it.

700%
More B12 than beef muscle
10x
More iron than spinach (heme form)
5x
More folate than kale per serving

Before Detox Teas, There Was Beef Liver

For over 2 million years, liver was the most prized food on earth, saved for warriors and the sick. Healers gave it for fatigue and weakness. Somewhere between processed food and detox teas, we forgot it. Lonvera is bringing it back, without the taste.

What Doctors Say About Liver Stress and Beef Liver

If a doctor has mentioned your liver enzymes, here's what liver and nutrition experts say about beef liver.

AT

Dr. Angela Torres, M.D.

Internal Medicine & Hepatology
I've been recommending beef liver to patients with liver stress, iron deficiency, and chronic fatigue for years. The nutrient density is unmatched. Lonvera's capsule format removes the biggest barrier — taste — while delivering the same bioavailable nutrients as fresh liver. This is exactly what patients with sluggish detox pathways need to restart their liver function.
MH

Dr. Michael Hart, D.O.

Functional & Regenerative Medicine
Liver is the only food that naturally contains pre-formed vitamin A, heme iron, B12, folate, copper, and CoQ10 in a single source — all of which are required for Phase I and Phase II liver detoxification. Synthetic supplements can't replicate this synergy. For patients who come to me exhausted, foggy, and inflamed, beef liver is where I start before anything else.
RC

Dr. Rachel Chen, Ph.D., RD

Nutritional Biochemistry & Dietetics
From a pure nutritional science perspective, no food comes close to beef liver in terms of micronutrient density per calorie. What makes Lonvera's approach particularly sound is the freeze-drying process — heat-based drying destroys enzymes and some heat-sensitive vitamins. Freeze-dried liver in capsule form is genuinely the next best thing to eating fresh grass-fed liver three times a week.

Zero Questions Asked

Common Questions, Straight Answers

How long until I notice results? +

Most customers feel more energy and better sleep within 7–14 days, and many notice less bloating after meals in the first week. Bigger changes build over weeks 2–4, and full liver benefits build over 90 days. That's when Javier L. had his follow-up bloodwork.

Will it send me to the bathroom like the detox teas? +

No. This isn't a cleanse or a laxative. It's freeze-dried grass-fed beef liver, which is food, and it's gentle on the stomach. Take 3 capsules with breakfast and go about your day. Nothing in it sends you running for the bathroom.

What's the recommended dosage? +

3 capsules with breakfast. After 1–2 weeks you can go up to 6 capsules a day for a more intensive protocol. Taking it with food improves absorption and prevents any chance of nausea.

I already eat clean. Why would I need this? +

Eating clean cuts calories, but it doesn't add the nutrients your liver uses to process fat: vitamin A as retinol, copper, B12 and heme iron. Most clean diets have almost no organ meat. Beef liver, often called nature's multivitamin, fills that gap in 3 capsules.

Will I taste or smell the liver? +

No. Zero taste, zero smell. The capsules are sealed, odorless and flavorless. Marcus W., 58, despises the taste of liver. His words on these: "Zero taste, zero smell, just results."

Is this safe if I'm on medications? +

Beef liver capsules are a whole food and generally safe alongside most medications. If you're on blood thinners (warfarin), be aware that vitamin K in liver can interact with dosing — consult your doctor. If you're on iron supplements already, speak with your doctor before adding more iron from liver. Otherwise, beef liver has an excellent safety profile.

What does "grass-fed and grass-finished" mean — and why does it matter? +

"Grass-fed" alone means the cattle ate grass at some point but may have been grain-finished before slaughter — which significantly changes the fat and nutrient profile. "Grass-finished" means the animals ate grass their entire lives. This matters because grass-finished liver has substantially higher omega-3 content, more conjugated linoleic acid (CLA), and a better fat-soluble vitamin profile than conventionally raised or grain-finished sources. Lonvera sources exclusively grass-fed and grass-finished beef liver.

What if it doesn't work for me? +

You're covered by our 60-day money-back guarantee. If your bloating, energy and belt haven't changed after a full 60 days, email support@lonvera.com and we'll refund you 100%. No questions, no hassle, no need to return the bottles. Unlike the teas, you only pay if it works.

Back to a Notch You Haven't Used in Years

The next beach day, the shirt comes off. The belt moves one notch in. And your liver finally gets the food nutrients it was missing, in 3 capsules with breakfast and zero taste. Try it risk-free for 60 days.
