The term "liquid gold" is increasingly associated with various health and wellness products, each claiming unique benefits. From bovine colostrum supplements to bone broth and even a vibrant juice recipe, the promise of improved health, weight loss, and overall well-being is drawing significant attention. This article delves into the science and claims surrounding these "liquid gold" options, examining their potential benefits and limitations.
Bovine Colostrum: A Closer Look
Bovine colostrum, the first milk produced by cows after giving birth, is gaining popularity as a supplement touted for its numerous health benefits. Wellness influencers and social media content creators are actively promoting it, highlighting its rich composition of antibodies, proteins, carbohydrates, and fats that support newborn calves' immune systems, growth, and overall health.
Composition and Differences from Human Colostrum
While humans also produce colostrum after giving birth, providing newborns with essential nutrients and antibodies, it's crucial to understand the differences between human and bovine colostrum. Human colostrum is specifically designed to benefit human infants, while bovine colostrum caters to the needs of bovine animals. For instance, bovine colostrum contains immunoglobulin G (IgG) as the dominant immunoglobulin, whereas human colostrum primarily contains immunoglobulin A (IgA). Furthermore, bovine colostrum generally exhibits higher levels of immunoglobulins, lactoferrin, and total protein content.
Claims and Evidence
Despite its growing popularity, the evidence supporting the purported health benefits of bovine colostrum for human adults remains mixed, limited, or even non-existent, according to dietitians and researchers. The most commonly touted benefits include:
Strengthening Immunity
Bovine colostrum contains immuno-active compounds like enzymes, cytokines, and immunoglobulins. A 2024 narrative review suggested that bovine colostrum supplementation might enhance the ability to fight respiratory and gastrointestinal infections across various age groups. However, a smaller, older study from 2006 involving male distance runners indicated that bovine colostrum supplementation led to more immune biomarkers and fewer self-reported upper respiratory symptoms. It is important to note that improved biomarkers do not automatically translate to fewer days of illness.

Experts emphasize that while bovine colostrum is rich in immune-boosting elements like IgG, more research is needed to confirm its effectiveness in boosting immunity in adults. Existing research often lacks randomization and fails to account for other factors that influence immune health, making it difficult to generalize the findings.
Athletic Recovery and Performance
The theory behind bovine colostrum's potential benefits for athletic recovery and performance stems from its content of insulin-like growth factors (IgF-1 and IgF-2), which may improve muscle recovery, performance, and growth. A 2018 study involving soccer players suggested that daily doses of 3.5 grams of bovine colostrum reduced muscle soreness and enhanced performance. Additionally, a 2021 narrative review indicated that some studies suggest that bovine colostrum might help with body composition and recovery. However, the research remains limited, and study designs often fail to account for other relevant variables.
Gut Health
While improved gut health is a well-known benefit of nursing for human newborns, bovine colostrum is also being promoted as a gut-health booster. However, more research is needed to substantiate these claims.
Bone Broth: A Traditional Remedy Reimagined
Bone broth, often referred to as "liquid gold," has gained recognition for its potential health benefits. It is made by simmering animal bones for extended periods, typically with vegetables, resulting in a nutrient-rich broth containing type 2 collagen, which is primarily found in animal bones and connective tissue.
Benefits of Bone Broth
Gut Health Improvement
Bone broth is rich in collagen, a crucial structural protein found in mammal tissues. Consuming bone broth may help improve gut health, particularly as the body's natural collagen production declines with age. The amino acids proline and glycine, present in collagen, contribute to its beneficial effects.

Skin Health
Collagen is vital for skin health, and consuming bone broth may enhance skin elasticity and hydration. While collagen additives in beauty creams may not be as effective, consuming collagen through bone broth can be beneficial. Increasing bone broth intake might also reduce the appearance of cellulite.
Immune System Support
Bone broth may support the immune system, aligning with the traditional use of chicken soup for comfort and healing during illness. The collagen-rich nature of bone broth may aid in restoring collagen levels and improving cellular repair processes.
Joint and Bone Health
Bone broth is packed with nutrients like hyaluronic acid, glucosamine, chondroitin, calcium, and magnesium. Studies suggest that consuming collagen-rich foods and supplements can significantly reduce joint pain and increase bone mineral density, particularly beneficial for postpartum, menopausal, and older women.
Making Bone Broth at Home
Making bone broth at home is a simple process. It involves simmering animal bones in water for an extended period, typically around 48 hours. While it requires time, the process is straightforward, and ready-made options are also available.
Dr. Kellyann's Perspective
Dr. Kellyann Petrucci, a proponent of bone broth, emphasizes its ability to heal the gut and slow aging. She highlights that bone broth is more than just broth or soup; it is a concentrated source of healing. Her diet focuses on using bone broth to reduce inflammation and promote weight loss.

Liquid Gold Juice: A Plant-Based Elixir
Another "liquid gold" contender is a vibrant juice recipe designed to improve health and elevate mood, particularly during seasonal transitions. This plant-based juice combines various fruits and vegetables to offer a range of benefits.
Benefits of Liquid Gold Juice
Digestion
The inclusion of ginger root and celery makes this juice beneficial for digestion, potentially reducing belly bloating and promoting regular elimination.
Inflammation
Turmeric root, with its active compound curcumin, and pineapple, containing bromelain, contribute to the juice's anti-inflammatory properties, aiding in muscle recovery and repair.
Detoxification
Granny Smith apples, rich in malic acid, stimulate the metabolism and help detoxify heavy metals from the body.
Immunity
The juice provides a significant dose of Vitamin C, supporting skin health and boosting the immune system.
Liquid Gold Juice Recipe
The recipe includes fresh-squeezed orange juice, celery, Granny Smith apples, pineapple, ginger, and turmeric. The ingredients are juiced and combined to create a refreshing and healthful beverage.
Liquid Carnitine: Enhancing Weight Loss and Performance
Liquid carnitine is a supplement that plays a crucial role in energy production, aiding the body in breaking down fat for fuel. It is often considered a "cheat code" compared to pills or capsules because it is pre-dissolved, allowing for faster absorption.
Benefits of Liquid Carnitine
Stimulant-Free Energy
Liquid carnitine is typically stimulant-free, making it suitable for individuals sensitive to stimulants and allowing for use at any time of day.
Weight Loss Support
L-carnitine assists the body in metabolizing fat for energy, making it a valuable supplement for weight loss when combined with a calorie-controlled diet.
Enhanced Athletic Performance
Athletes and fitness enthusiasts may use liquid carnitine to enhance endurance and improve fat utilization during exercise. It may also increase oxygen supply to working muscles.
Muscle Recovery
Some individuals use liquid carnitine to aid muscle recovery after intense exercise and reduce post-exercise muscle soreness.
Considerations for Use
The decision to use liquid carnitine should be based on individual needs and goals. It may be particularly beneficial for individuals with carnitine deficiency or those who do not consume enough meat or dairy.
Liquid Gold PRP: Skin Rejuvenation
Liquid Gold PRP, or Platelet-Rich Plasma, is a medical treatment that uses the patientâs own blood to stimulate tissue repair and rejuvenation.
Benefits of Liquid Gold PRP
Skin Rejuvenation
PRP stimulates collagen production and improves skin texture, tone, and elasticity, while reducing the appearance of fine lines, wrinkles, and scars. Some Liquid Gold add-ons for PRP can help to enhance the skinâs hydration and plumpness or add antioxidant properties, helping to brighten the skin.
