Pure Encapsulations Amino-NR

After a long or intense session, your muscles aren't the only thing running short, your glutamine levels drop too, which is tied to the temporary immune dip that shows up at higher training volumes. Free-form amino acids are one of the more direct ways to support both muscle recovery and that immune dip at once.

Amino-NR from Pure Encapsulations combines free-form amino acids in the same ratios found in high-biological-value protein sources, plus alpha lipoic acid and active B12 for the mitochondrial side of energy production.

Supports muscle performance and recovery – Free-form amino acids are studied for supporting muscle performance and recovery after training, based on the natural ratios found in high-BV protein sources like eggs and whey.

Backs the immune dip that follows hard training – These same amino acids support glutamine and glutathione levels, both of which drop during and after intense exercise and are tied to the temporary immune dip athletes experience at high training volumes.

Fuels the mitochondrial side of energy production – Alpha lipoic acid and adenosylcobalamin, an active form of B12, support mitochondrial function, the cellular machinery responsible for producing ATP.

This formula's free-form amino acids are matched to the natural ratios found in high-biological-value protein, the kind your body absorbs and uses directly without needing to break down whole protein first. Vitamin B6 acts as a cofactor for amino acid and energy metabolism, while alpha lipoic acid and adenosylcobalamin, the vitamin B12 form active inside mitochondria, support cellular energy production that depends on enzyme activity known to decline with age. A few additional claims about muscle fiber type and neuromuscular effects trace back to unpublished internal research rather than peer-reviewed studies, so this copy sticks to the published research behind the amino acid, glutamine, and mitochondrial mechanisms.

How To Use Amino-NR

Dose: Take 3 capsules, 1-2 times daily, between meals.

Heavy training days: Lean toward the twice-daily dose on your hardest training days, when muscle recovery and immune support both matter most. This product contains phenylalanine, which matters specifically for anyone with phenylketonuria (PKU).
