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............

The Nutrients

6 Powerhouse Nutrients Working Together Inside Every Capsule

Beef liver isn't just iron. It's a complete matrix of synergistic nutrients that modern diets have almost entirely eliminated — each playing a specific, critical role.

🩸

Heme Iron

Most bioavailable form on earth

The iron found in beef liver is absorbed 2–3x more efficiently than non-heme iron from plants. Critical for red blood cell production, oxygen transport, and eliminating that bone-deep fatigue.

✓ Up to 300% better absorption than plant iron
⚡

Vitamin B12 (Cobalamin)

700% more than muscle meat

The master energy vitamin. B12 is required for nerve function, DNA synthesis, and every mitochondrial energy reaction. Deficiency causes brain fog, fatigue, and depression — and 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) — which only animal sources provide — is required for liver detoxification Phase I enzymes, skin cell renewal, and immune signaling. The beta-carotene in carrots is a poor substitute that most people can't convert efficiently.

✓ Directly usable — no conversion required
🔮

Copper

Critical trace mineral

Copper works with iron to form red blood cells, powers your immune defense, and catalyzes bile production in the liver. Deficiency — increasingly common in modern diets — impairs every one of these functions simultaneously.

✓ Works synergistically with iron for max absorption
🧬

Folate (Vitamin B9)

5x more than kale per serving

Essential for DNA repair, cellular regeneration, and methylation — the liver's master detox process. Unlike synthetic folic acid in supplements, liver folate is the active, immediately usable form your body recognizes.

✓ Active natural form — superior to synthetic folic acid
🛡️

CoQ10 & Glutathione Precursors

The "master antioxidant" fuel

Beef liver is rich in the precursors your liver needs to produce glutathione — your body's most powerful antioxidant and the central molecule of Phase II liver detoxification. You can't supplement glutathione directly; your liver must make it. This provides the raw materials.

✓ Fuels your liver's own detox production

My ferritin was critically low post-pregnancy. My OB wanted me on prescription iron — the kind that causes horrible constipation. A friend recommended this instead. Six weeks later my ferritin went from 11 to 48. My OB was shocked and asked me what I was taking.

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.

Is This You?

7 Signs Your Liver Is Crying Out for Help

Your liver performs over 500 functions every day. When it's overloaded with toxins — from food, alcohol, medications, and pollution — these warning signs appear first.

🚨 The Modern Liver Crisis Is Real

Non-alcoholic fatty liver disease now affects 1 in 3 adults in the US. Most doctors don't catch it until it's advanced — because the early symptoms look like "just feeling tired." If you recognize any of the signs below, your liver is telling you something urgent.

😴

Constant Fatigue That Won't Quit

You sleep 7–8 hours and still wake up exhausted. A sluggish liver can't efficiently convert nutrients into usable energy — leaving you running on empty all day.

🧠

Brain Fog & Poor Concentration

When your liver isn't filtering toxins efficiently, those toxins accumulate in the bloodstream and reach your brain — causing the mental cloudiness millions chalk up to "getting older."

😣

Bloating & Digestive Discomfort

Your liver produces bile for fat digestion. A stressed liver means poor bile production — leading to bloating, gas, and that heavy, uncomfortable feeling after meals.

🌑

Dull Skin, Dark Circles, Yellowing

Your skin is a mirror of your liver. When detox pathways are backed up, it shows in dullness, dark circles under the eyes, and sometimes a yellowish tint to skin or eyes.

😰

Unexplained Weight Gain

The liver regulates fat metabolism and hormones. A compromised liver stores excess fat — especially around the belly — even when you're watching what you eat.

💊

Tried Everything & Still Feel Off

You've tried detox teas, supplements, diet changes. They don't work because they don't give the liver what it actually needs — concentrated, bioavailable nutrients to rebuild its detox machinery.

As Featured In

🔬 Liver-to-Liver Healing: How It Works

1

The Problem: Your Liver Is Nutrient-Depleted

Modern diets strip out the liver-specific nutrients that feed detoxification enzymes. Without them, toxin pathways stall completely.

2

The Principle: "Like Supports Like"

Nature's oldest health principle: consuming an organ nourishes that same organ in your body. Beef liver delivers nutrients that no plant food can replicate.

3

The Delivery: Pre-formed & Bioavailable

Unlike synthetic vitamins, beef liver nutrients come pre-formed — especially vitamin A (retinol), B12, and heme iron — meaning your body absorbs and uses nearly all of it.

4

The Result: Detox Pathways Reopen

Phase I and Phase II liver detoxification enzymes are fueled and restored. Your liver flushes toxins the way it was designed to — and your energy, skin, and clarity follow.

Why Grass-Fed Beef Liver Is Genuinely Nature's Most Powerful Detox Food

Pound for pound, beef liver contains more essential nutrients per calorie than any other food on earth — including spinach, blueberries, salmon, and eggs combined. This isn't marketing. It's documented nutritional science.

The problem? Most people won't eat liver. It tastes strong, it's inconvenient, and traditional recipes have fallen out of modern life. Lonvera's capsules give you the full nutritional power of fresh grass-fed liver — with zero taste and total convenience.

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.

More B12 than beef muscle

Before Big Pharma, Beef Liver Was the Original Medicine

For over 2 million years of human evolution, liver was the most prized food on earth — reserved for warriors, pregnant mothers, and the ill. Ancient healers prescribed it for fatigue, weakness, and "blood diseases" (iron deficiency). Indigenous cultures around the world gave liver to their youngest and oldest first. Somewhere between the rise of processed food and synthetic vitamins, we forgot this entirely. Lonvera is bringing it back.

What Doctors & Nutritionists Say About Beef Liver

The science on whole-food liver nutrition is decades old — and the medical community is increasingly recommending it.

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.

FAQ

Common Questions, Straight Answers

How long until I notice results? +

Most customers feel an improvement in energy and sleep within 7–14 days. The more significant shifts — clearer skin, reduced brain fog, improved digestion — typically happen between weeks 2–4. Full liver restoration benefits build over 90 days. If you have significant iron or B12 deficiency, improvements can come even faster.

Is this safe during pregnancy or breastfeeding? +

Beef liver is one of the most nutritionally complete foods for pregnancy — rich in folate, iron, B12, and retinol, all of which are critical for fetal development. However, because vitamin A (retinol) in excess can be harmful during pregnancy, we recommend consulting your OB-GYN about your specific dosage. Many pregnant women take 2–3 capsules daily with their doctor's approval.

What's the recommended dosage? +

We recommend starting with 3 capsules daily with a meal. Once you're comfortable (after 1–2 weeks), you can increase to 6 capsules per day for a more intensive protocol. Taking with food improves absorption and prevents any chance of nausea. Start low and build up — your body will tell you what it needs.

Can I take this instead of my multivitamin? +

For most people, yes — beef liver is so nutrient-dense that it effectively replaces the need for a multivitamin, particularly for B vitamins, iron, copper, and vitamin A. The key difference is that every nutrient in beef liver is in its natural, bioavailable, food-matrix form — which your body recognizes and absorbs far more efficiently than synthetic vitamins in most multivitamins.

Will I taste or smell the liver? +

No. Absolutely zero liver taste or smell. The capsules are sealed, odorless, and flavorless. This is one of the top reasons our customers prefer capsules over beef liver powder or raw liver — all of the nutrition, none of the flavor.

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 fully covered by our 60-day money-back guarantee. If you don't notice meaningful improvements in your energy, clarity, and how you feel after a full 60 days, simply email support@lonvera.com and we'll refund you 100%. No questions, no hassle, no requirement to return the bottles.

Your Liver Has Been Waiting for This

Every day of depleted energy, foggy thinking, and backed-up toxins is a day your liver is running on empty. Give it what it was designed to thrive on — and feel what your body is capable of when it's finally working the way nature intended.
