Frailty
Frailty is a clinical syndrome characterized by an age-associated decline in strength, muscle mass (sarcopenia), and physical reserve that increases the risk for falls, disability, hospitalization, and death.
Quick Answer
What it is
Frailty is a clinical syndrome characterized by an age-associated decline in strength, muscle mass (sarcopenia), and physical reserve that increases the risk for falls, disability, hospitalization, and death.

Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Essential for muscle maintenance; higher requirements in elderly; prevents sarcopenia
Deficiency extremely common in frail elderly; affects muscle function, falls, bone health
Supporting Stack (Tier 2)
Supports muscle strength and function; may enhance benefits of resistance training in elderly
Anti-inflammatory; may help preserve muscle mass and reduce inflammation associated with frailty
Leucine metabolite; may help preserve muscle mass in elderly; reduces muscle breakdown
Deficiency common in elderly; affects neurological function and energy
Often deficient in elderly; supports immune function and wound healing
Supports cellular energy production; levels decline with age; may improve fatigue
How It Works
Frailty is a clinical syndrome characterized by decreased resilience and increased vulnerability to stressors. It's distinct from normal aging and represents a state where minor events (like an infection or medication change) can trigger major functional decline.
FRAILTY PHENOTYPE (Fried Criteria):
3 or more of:
STAGES:
RISK FACTORS:
CONSEQUENCES:
MOST IMPORTANT INTERVENTIONS:
1. Exercise - especially resistance/strength training
2. Nutrition - adequate protein and calories
3. Medication review - reduce polypharmacy
4. Comprehensive geriatric assessment
* Protein (1.2-1.5g/kg/day) is essential - elderly need MORE protein, not less.
* Vitamin D deficiency is extremely common and affects muscle function.
* Creatine + resistance training may have synergistic benefits.
* Exercise is the MOST effective intervention - even in very frail individuals.
Expected timeline: Frailty can be reversed, especially from pre-frail state. Improvements may be seen in weeks to months with consistent exercise and nutrition.

This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.

Type 2 Diabetes
4 shared supplements Β· 868 outcomes
Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

General Athletic Performance

General athletic performance refers to an individual's ability to perform in various sports and physical activities, including strength, speed, endurance, and agility.
Obesity
3 shared supplements Β· 525 outcomes
Obesity is a condition of excessive body fat that increases the risk for other conditions such as diabetes and heart disease. Fat is how the body stores extra calories that were eaten but not used. Obesity treatment usually involves restricting the calories eaten or creating a negative calorie balance.

Muscle Size & Strength

This page on muscle size and strength covers strategies to maximize muscle gain and strength gain. There is notable overlap in nutrition and supplementation strategies to facilitate these two goals, but there is some divergence in the best type of exercise. A larger muscle tends to be a stronger muscle.
