Whey Protein

Overview

Whey protein provides high-quality complete protein (DIAAS 118-122) and nicotinamide riboside, an efficient NAD+ precursor supporting mitochondrial function. Whey protein isolate has DIAAS 118–122 with no limiting amino acids, high leucine content, and supports BDNF and neurotransmitter synthesis.

Food Context

Synergies

• Part of protein strategy for brain health

Preparation

• Can be used as supplement or in smoothies
• High-quality protein source
• Supports mitochondrial NAD+ availability

Essential Amino Acid Profile

Whey Protein contribute plant protein. Pair with complementary protein sources (e.g. grains and legumes) for a balanced essential amino acid profile.
