Sarcopenia
Sarcopenia is a condition characterized by a progressive loss of muscle mass and strength. It arises as a consequence of aging or is caused by factors like disease, physical inactivity, or inadequate nutrition. Resistance training and a high-protein diet are the primary treatments for sarcopenia.

Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Provides essential amino acids to stimulate muscle protein synthesis; addresses anabolic resistance in aging
Enhances muscle strength, power, and mass; particularly effective when combined with resistance training
Supporting Stack (Tier 2)
Deficiency linked to muscle weakness; supplementation improves muscle function in deficient individuals
Leucine metabolite that reduces muscle protein breakdown and may help preserve muscle mass
May enhance muscle protein synthesis response to protein intake and reduce inflammation affecting muscle
Key amino acid for activating muscle protein synthesis; overcomes age-related anabolic resistance
Provide all amino acids needed for muscle protein synthesis in easily absorbed form
Supports mitochondrial energy production in muscle cells; levels decline with age
Supports fatty acid metabolism for muscle energy; may reduce fatigue and improve function
How It Works
Sarcopenia is the age-related loss of muscle mass, strength, and function that begins around age 30-40 and accelerates after 60. By age 80, people may lose up to 50% of their muscle mass. This leads to weakness, falls, fractures, loss of independence, and increased mortality. Multiple factors contribute: reduced physical activity, inadequate protein intake, hormonal changes, chronic inflammation, and what's called 'anabolic resistance'—aging muscles don't respond as well to the signals that normally build muscle.
IMPORTANT: Resistance exercise is the most powerful intervention for sarcopenia—supplements support but can't replace physical activity. A combination of exercise and nutritional strategies is most effective. Underlying conditions affecting muscle (diabetes, thyroid disorders, malnutrition) should be addressed.
Expected timeline: Protein and amino acids: ongoing support. Creatine: 2-4 weeks to saturate muscle stores. Vitamin D (if deficient): 2-3 months to replenish. Best results require consistent supplementation combined with resistance exercise for 3-6 months minimum.

Muscle Size & Strength
4 shared supplements · 334 outcomes
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.

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
3 shared supplements · 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.

Obesity
2 shared supplements · 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.
Metabolic Syndrome

Metabolic syndrome refers to a group of cardiometabolic risk factors: abdominal obesity, high blood pressure, high fasting blood sugar, high blood triglycerides, and low HDL-C. If a person has at least three of these, they have metabolic syndrome.
