5 Nutrients You're Probably Missing - And How Ancestral Blend Beef Sticks Can Help

You eat well. You try to make smart choices. But here's an uncomfortable truth that nutrition researchers have been documenting for years: even health-conscious people are routinely low on a handful of essential nutrients - ones that are difficult to get from conventional food sources, nearly impossible to get from supplements alone, and almost never discussed outside of specialist circles.

The reason? Modern diets have largely cut out the parts of the animal that our ancestors prized most: the organs.

Below, we break down five nutrients that are quietly missing from most people's diets, why each one matters - especially for busy, active adults managing packed schedules - and how BERSKI ancestral blend beef sticks make replenishing them genuinely simple.

1. Vitamin B12: The Energy and Brain Health Essential

Why you're probably low

B12 is found almost exclusively in animal products - but the specific animal products most people eat (chicken breast, ground beef, eggs) contain relatively modest amounts. The organs - particularly liver - contain concentrations of B12 that muscle meat simply can't match. Research from the NIH estimates that roughly 6% of adults under 60 are clinically deficient, with many more in a "suboptimal" range that doesn't show up on standard bloodwork.

Why it matters

B12 is central to red blood cell formation, neurological function, and DNA synthesis. Low levels are associated with fatigue, brain fog, and mood disruption - symptoms that are easy to attribute to stress or a bad night's sleep rather than nutritional gaps.

How BERSKI helps

Each BERSKI beef stick blends muscle meat with beef liver - one of the most concentrated natural sources of B12 on the planet. One serving delivers a meaningful dose in a form your body recognizes and absorbs efficiently, with no cooking, no prep, and no planning required.

2. Heme Iron: The Form of Iron Your Body Actually Absorbs

Why you're probably low

Iron deficiency is the world's most common nutritional deficiency, affecting an estimated 25% of the global population according to the World Health Organization. In the United States, it disproportionately affects women of reproductive age, pregnant individuals, and athletes - but it's more widespread than most people realize. The catch: most dietary iron people consume is non-heme iron from plant sources, which has a bioavailability of just 2–20%. Heme iron, found only in animal products, is absorbed at rates of 15–35%.

Why it matters

Iron is required for oxygen transport throughout the body. Even mild iron insufficiency - well short of clinical anemia - can cause persistent fatigue, reduced cognitive performance, and a weakened immune response. For parents managing a household and professionals pushing through demanding days, suboptimal iron can quietly erode energy and focus.

How BERSKI helps

Beef organ meats - particularly liver - are among the richest dietary sources of highly bioavailable heme iron. BERSKI's ancestral blend puts these ingredients into a portable, shelf-stable format so you can support healthy iron levels without building your life around meal prep.

3. CoQ10: The Cellular Energy Compound Most People Have Never Heard Of

Why you're probably low

Coenzyme Q10 is produced naturally in the body, but production declines significantly with age - starting as early as your 30s. The richest dietary source of CoQ10 is beef heart, which contains concentrations three to four times higher than skeletal muscle. Because beef heart has largely disappeared from modern diets, most adults rely entirely on endogenous production - which is increasingly insufficient as the years pass.

Why it matters

CoQ10 plays a fundamental role in mitochondrial function - the process by which your cells generate energy. It also acts as a potent antioxidant, protecting cells from oxidative damage. Research has linked CoQ10 to cardiovascular health, physical performance, and reduced fatigue. Some studies suggest it may help offset the energy-depleting side effects of statin medications, which block the body's own CoQ10 synthesis.

How BERSKI helps

Beef heart is a core component of BERSKI's ancestral blend - providing a natural, food-matrix source of CoQ10 that supplements simply can't replicate. The advantage of getting CoQ10 from whole food rather than isolated supplements is that it comes alongside a full complement of cofactors that support absorption and utilization.

4. Zinc: Immunity, Hormones, and Recovery

Why you're probably low

Zinc insufficiency is more common than clinical deficiency figures suggest. Factors like high-carbohydrate diets, soil depletion, alcohol consumption, and intense exercise all increase zinc losses or inhibit absorption. The body has no dedicated zinc storage system, which means it depends on consistent dietary intake. Organ meats - particularly beef liver - are among the most zinc-dense foods available.

Why it matters

Zinc is involved in over 300 enzymatic reactions in the body. It's critical for immune function, wound healing, protein synthesis, testosterone production, and taste and smell. People who are chronically stressed - and that includes most parents and high-performing professionals - tend to burn through zinc at an accelerated rate.

How BERSKI helps

The liver and muscle meat combination in BERSKI beef sticks delivers a meaningful hit of highly bioavailable zinc in every serving - supporting immune resilience and recovery without the need for additional supplementation.

5. Retinol (Preformed Vitamin A): The Form That Actually Works

Why you're probably low

There is an important distinction that mainstream nutrition often glosses over: beta-carotene (from plant foods like carrots) is not the same as retinol (preformed vitamin A from animal sources). The human body must convert beta-carotene into retinol - and that conversion is highly variable. Research suggests the conversion ratio can be as poor as 28:1 in some individuals, meaning that relying on vegetables for vitamin A may leave significant gaps, particularly for people with genetic variants that affect conversion efficiency.

Why it matters

Retinol is essential for vision, immune function, skin health, and cellular communication. It plays a particularly important role in reproductive health and fetal development. Beef liver is the single richest dietary source of retinol - by a considerable margin.

How BERSKI helps

Because BERSKI's blend includes beef liver, each stick provides a source of true preformed retinol - the kind your body can use immediately, without relying on a conversion process that may or may not be working optimally.

The Bottom Line

Nutritional gaps don't always announce themselves with dramatic symptoms. More often, they show up quietly - as fatigue you can't explain, focus that slips in the afternoon, or a nagging sense that your body isn't running at its best. The five nutrients above represent some of the most common and consequential gaps in modern diets, and they share a common solution: eating the way humans ate for most of our evolutionary history, including the nutrient-dense organs that our ancestors knew were the most valuable part of the animal.

BERSKI ancestral blend beef sticks are built around that principle. We've taken the nutrition of nose-to-tail eating - liver, heart, and high-quality muscle meat - and put it into a clean, convenient format that fits a modern life. No cooking required. No unusual flavors to push through. Just real food, with real nutritional density, whenever you need it.
