The Brains Behind the Blend
Meet Dr. Dan
Dr. Daniel Davis – Co-Founder & Creator
Sports Medicine Specialist | Performance & Recovery Advocate
With over 20 years of experience in orthopedic and sports medicine, Dr. Daniel Davis has helped thousands of people overcome injuries, restore movement, and get back to the activities they love. As a board-certified physician, he’s worked with everyone from weekend walkers to professional athletes — but his passion lies in helping everyday people stay active, healthy, and pain-free for life.
Frustrated by the overwhelming number of under-dosed and over-marketed supplements, Dr. Davis set out to create a solution that combined his medical expertise with simple, effective nutrition. The result is Dr. Dan’s Killer Blend™ — a research-driven, all-in-one formula designed to support recovery, maintain strength, and improve overall wellness without the clutter of dozens of separate products.
Why Our Formula Works Better Together
Ingredient Synergy for Max Impact
By combining clinically studied compounds that complement each other’s effects, Dr. Dan’s Killer Blend delivers benefits far beyond what single ingredients can achieve alone. Creatine and beta-alanine team up to fuel muscles and delay fatigue, citrulline and arginine work together to boost blood flow and nutrient delivery, and HMB with glutamine help protect and rebuild muscle tissue. This multi-pathway approach enhances endurance, speeds recovery, preserves lean mass, and keeps active adults feeling strong, energized, and ready for whatever the day brings.
The Science Behind the Blend
Every scoop contains proven nutrients, each shown to boost energy, recovery, endurance, and overall wellness — here’s what’s inside and why it works.
Creatine — Energy & Strength
Creatine is your body’s go-to energy reserve during short, intense bursts of activity. By increasing phosphocreatine stores in muscle, it allows you to produce more ATP — your muscles’ main fuel.
More details
Benefits:
Supports strength and power for everyday activities
Helps preserve lean muscle with age
May enhance cognitive performance in some studies
Key Evidence:
Supplementation increases muscle phosphocreatine by up to 20%, improving performance in high-intensity efforts (CREATINE REVIEW.pdf)
Long-term use can help offset age-related muscle loss by supporting protein synthesis (CREATINE + HMB.pdf)
In-Depth Science:
Creatine is a nitrogenous organic acid synthesized in the liver, kidneys, and pancreas from the amino acids arginine, glycine, and methionine. Approximately 95% of the body’s creatine is stored in skeletal muscle as free creatine and phosphocreatine (PCr). During short-duration, high-intensity activity, phosphocreatine donates a phosphate group to ADP to rapidly regenerate ATP — the primary energy currency of cells. This replenishment process allows muscles to sustain maximum effort for longer periods.
Beyond acute performance, creatine has been shown to increase total muscle creatine content by ~20%, supporting enhanced protein synthesis via mTOR pathway activation, improved satellite cell signaling, and reduced muscle protein breakdown. It may also act as an osmolyte, drawing water into muscle cells and creating an anabolic environment. In older adults, creatine supplementation combined with resistance training can significantly improve lean body mass, muscle strength, and functional performance, and may have neuroprotective benefits through improved brain phosphocreatine availability.
HMB — Muscle Preservation & Repair
HMB (beta-hydroxy beta-methylbutyrate) helps reduce muscle protein breakdown and supports repair, particularly during times of physical stress or inactivity.
More details
Benefits:
Helps maintain muscle mass during periods of reduced activity
Supports faster recovery after strenuous or unfamiliar activity
Reduces soreness and muscle damage markers
Key Evidence:
HMB supplementation can reduce muscle protein breakdown by up to 57% in certain conditions (HMB in healthy and wasting conditions.pdf)
Improves strength and lean body mass when combined with resistance exercise in older adults (Review of glutamine, HMB and arginine.pdf)
In-Depth Science:
HMB is a metabolite of the essential amino acid leucine and plays a critical role in regulating muscle protein turnover. It inhibits the ubiquitin-proteasome pathway, a key system responsible for muscle protein degradation, while stimulating protein synthesis through mTOR signaling.
For active adults — especially during aging — maintaining muscle mass is critical for functional independence. HMB supplementation can help preserve lean mass during periods of inactivity (e.g., injury recovery) and improve training outcomes when activity is resumed. It also has anti-catabolic effects that are beneficial for minimizing muscle loss with age-related sarcopenia.
Beta-Alanine — Endurance & Performance
Beta-alanine increases muscle carnosine levels, which act as a buffer against lactic acid buildup. This helps delay fatigue during prolonged or high-effort activities so you can sustain performance longer.
More details
Benefits:
Reduces muscle fatigue during sustained activity
Improves ability to handle daily tasks without feeling “worn out”
Supports better exercise tolerance over time
Key Evidence:
Chronic beta-alanine supplementation can increase muscle carnosine content by 40–80% (Beta alanine review.pdf)
Improved time-to-exhaustion and performance in tasks requiring sustained muscle contraction
In-Depth Science:
Beta-alanine is a non-essential amino acid that combines with histidine in muscle cells to form carnosine, an intracellular buffer. Carnosine neutralizes hydrogen ions (H⁺) produced during anaerobic glycolysis, helping maintain optimal pH levels inside muscle cells. This buffering action delays the onset of muscle acidosis, a key contributor to fatigue during prolonged or high-intensity efforts.
For aging adults, higher carnosine levels can improve daily endurance, allowing more consistent activity without exhaustion. Studies show that beta-alanine supplementation can significantly improve both athletic and functional performance in older populations by extending time-to-fatigue and supporting greater training volume.
Citrulline + Arginine — Circulation & Recovery
These amino acids work together to boost nitric oxide (NO) production, improving blood flow, oxygen delivery, and nutrient transport to working muscles.
More details
Benefits:
Supports healthy circulation for better overall energy
Helps reduce post-activity soreness
Aids in faster recovery between bouts of activity
Key Evidence:
Citrulline supplementation increases plasma arginine levels more effectively than arginine alone (Citrulline increases arginine levels.pdf)
Enhanced NO production is linked to improved blood flow and reduced fatigue (Citrulline + Arginine.pdf)
In-Depth Science:
L-citrulline is converted into L-arginine in the kidneys, which then serves as the substrate for nitric oxide synthase (NOS) to produce nitric oxide. NO acts as a potent vasodilator, relaxing blood vessels to enhance blood flow. While L-arginine itself can boost NO, much of it is metabolized before reaching the bloodstream, making citrulline a more effective precursor.
The improved circulation from NO production increases oxygen and nutrient delivery to muscle tissue, facilitating quicker recovery and reducing delayed-onset muscle soreness (DOMS). In older adults, supporting vascular function through the NO pathway can improve exercise tolerance, energy levels, and cardiovascular health.
Glutamine — Immune & Recovery Support
Glutamine is the most abundant amino acid in the body, essential for immune cell function, intestinal health, and recovery from physical stress.
More details
Benefits:
Supports immune health, reducing downtime from illness
Aids in muscle repair and glycogen replenishment post-activity
Helps maintain gut health under stress
Key Evidence:
Glutamine depletion is associated with impaired immune function (Review of glutamine, HMB and arginine.pdf)
Supplementation can improve recovery markers after physical stress and illness
In-Depth Science:
Glutamine serves as a primary fuel source for rapidly dividing cells, including immune cells (lymphocytes, macrophages) and intestinal epithelial cells. During physical stress — from exercise, illness, or injury — glutamine demand can exceed supply, leading to immune suppression and slower recovery.
Supplementing with glutamine can help maintain plasma levels, supporting immune surveillance and gut barrier integrity. For active adults, this means fewer interruptions to activity due to illness, faster recovery from exertion, and improved overall resilience.
