[12:10] Protein's Role

Protein plays a vital role in the body, with muscle making up roughly 30–40% of your total composition. Its primary function is to support repair, recovery, and growth across muscles, bones, and organs.

Reference: Skeletal Muscle

[12:46] Protein & Metabolism

Protein is directly involved in metabolic processes throughout the body.

Reference: What are proteins and what do they do?

[12:48] Muscle & Fat Burning

The exercise of stimulating muscle growth helps you burn fat.

Reference: Non-exercise activity thermogenesis (NEAT)

[13:45] Collagen (Pt 2)

The amino acids in collagen help feed that part of the body. (hair, skin, nails)

[13:45] Collagen

Collgen for Hair Skin and Nails: Collagen entered market on anti-aging messaging. (hair, skin, nails).

Reference: Collagen peptides has beneficial effects on human skin physiology

[14:30] Whey Protein - Most Popular Protein

Whey protein is the most popular protein in the market.

[16:25] Protein Evaluation

Protein Scoring systems: scoring the best proteins for the human body

Reference: Dietary Protein Quality Evaluation in Human Nutrition

[17:00] Animal vs Plant Protein

Plant proteins have a low biological value score

Reference: A Review on Nutritional Quality of Animal and Plant Proteins

[17:25] DIAAS

The Digestible Indispensable Amino Acid Score (DIAAS) is considered the most sophisicated proteing scoring system.

Reference: Digestible indispensable amino acid score (DIAAS): 10 years on

[17:45] DIAAS and Plant Protein

Plant proteins score lower in DIAAS score.

Reference: Can the digestible indispensable amino acid score methodology decrease protein malnutrition

[18:15] DIAAS and Whey Protein

Whey protein gets over 100 on DIAAS score, plant proteins typically provide a DIAAS score around 70-80, and collagen gets a zero on DIAAS score.

[19:00] Whey Protein and Muscle Repair

Whey protein has the near perfect amino acid structure that is best for helping support muscle repair and recovery.

[21:00] Grass-Fed Whey

Grass-fed whey protein is important because its nutritional value differs from conventional options. Cows raised on grass produce higher-quality milk—where whey is derived—and are typically not treated with added hormones, resulting in a cleaner product for consumption.

[25:00] Probiotics

Probiotics are important for immune health and digestion.

[26:35] Melatonin

Melatonin is a synthetic hormone most of the time, at least 99.99% of the market.

[29:15] Creatine and HMB

HMB helps you retain muscle you worked so hard in the gym for. HMB also helps preserve muscle and in some cases help you build it back.

[29:45] Medicinal Mushrooms

Medicinal mushrooms: enhance brain function and immune function.

Reference: Mushroom immunomodulators: unique molecules with unlimited applications

[30:30] NMN

NMN in B-vitamin familiy sort of – came on scene due to anti-aging interest. NAD is not well absorbed or utiliezed and NMN seems to be better utilized.

Reference: Nicotinamide mononucleotide increases muscle insulin sensitivity in prediabetic women

[31:10] Energy Drinks

Energy drinks are dangerous. Stimulants can increase blood pressure and heart rate unnaturally.

[35:50] Absorption - Resveratrol

Less than 1% of Resveratrol is absorbed into the body.

Reference: High absorption but very low bioavailability of oral resveratrol in humans

[35:50] Absorption

Many supplements are poorly absorbed by the body (low bioavailability), meaning only a small percentage is actually utilized.

Reference: High absorption but very low bioavailability of oral resveratrol in humans
