ageLOC® R2 Day (Vitality) (Canada)

ageLOC R² Day (Vitality) is the daytime half of Nu Skin's R² cellular energy system, targeting mitochondrial ATP production — the energy currency your cells need for every biological process. The formula centres on Cordyceps sinensis (Cs-4 extract), a medicinal mushroom with centuries of traditional use and modern clinical evidence supporting its role in oxygen utilization and energy production. For Canadians who notice energy flagging by mid-afternoon, particularly during the dark winter months, R² Day provides cellular-level energy support that doesn't rely on caffeine or stimulants.

What Makes ageLOC R² Day Different

Energy supplements typically mean caffeine, B-vitamins, or adaptogenic herbs. R² Day works at a deeper level — supporting the mitochondria that actually generate cellular energy. Cordyceps Cs-4 has been shown in a randomized controlled trial (Chinese Journal of Integrative Medicine, 2010) to improve oxygen uptake and exercise capacity in adults over 12 weeks.

The ageLOC gene expression blend targets Youth Gene Clusters associated with cellular vitality, aiming to maintain youthful energy-production gene expression patterns. This isn't a quick energy hit — it's foundational support for how your cells produce energy at the genetic level.

R² Day is designed to pair with R² Night for a complete circadian-aligned system, but works effectively as a standalone energy supplement for those who want mitochondrial support without the nighttime purification component.

Key Ingredients

Cordyceps sinensis Cs-4 Extract: Standardized mushroom extract supporting mitochondrial ATP production and oxygen utilization. Clinical research confirms improved exercise capacity and reduced fatigue markers in supplemented adults.

Alpha-Lipoic Acid: A network antioxidant that crosses both fat and water cellular compartments, supporting mitochondrial function and regenerating vitamins C and E.

ageLOC Proprietary Blend: Targets vitality-related Youth Gene Clusters to maintain youthful energy-production gene expression.

How to Use

Take 2 capsules with breakfast each morning. Consistent daily use builds cumulative effects — most people notice improved sustained energy within 2–4 weeks. Don't expect a caffeine-like immediate buzz; this is cellular support, not stimulation.

During Canadian winters when 4:30 PM sunsets and perpetual grey skies compound natural energy decline, R² Day addresses the cellular energy deficit that light deprivation worsens.
