ageLOC® R² Day (AU)

ageLOC R² Day is the daytime half of Nu Skin's R² day-and-night anti-ageing system, sold here as a standalone unit. It targets cellular energy production during waking hours using Cordyceps sinensis Cs-4, pomegranate, and chokeberry extract. This listing is for customers who want to restock just the Day capsules (you typically run through Day before Night) or trial the daytime formula on its own. If you intend to use the full circadian system long-term, the combined R² box (AU$155) is around AU$21 cheaper than buying Day (AU$87.99) and Night (AU$88) separately.

What R² Day Targets

R² Day is built around mitochondrial ATP production — the actual energy currency every cell runs on. The body's mitochondrial output begins to decline from around age 30, which is why the same diet and sleep that worked at 25 don't deliver the same energy at 40. R² Day's actives address that decline at the cellular level rather than masking it with stimulation.

Cordyceps sinensis Cs-4 is the anchor ingredient. A 2010 trial in the Journal of Alternative and Complementary Medicine (Chen S, et al., 2010;16(5):585–590) found Cs-4 supplementation improved exercise performance and oxygen utilisation in older adults over 12 weeks. Pomegranate extract (standardised for punicalagins and ellagic acid) provides daytime antioxidant cover for the period when oxidative stress from UV, pollution, and metabolic activity is highest. Chokeberry extract contributes additional polyphenols for vascular and antioxidant support.

How It Differs from R² Night

R² Day and R² Night are not interchangeable — each formula targets the biological phase it's named for. Day works on mitochondrial energy production and daytime antioxidant defence. Night uses milk thistle, broccoli seed extract, and curcumin to support the liver's overnight phase II detoxification and the Nrf2 antioxidant pathway. The full circadian benefit only materialises when both halves run together; that's the design rationale for the system. Read the R² Hub page for the complete explanation of why the day/night split matters.

How Australians Are Using R² Day

Take the daily dose with breakfast — the carotenoid-class actives (pomegranate, chokeberry) are fat-soluble and absorb significantly better with a small amount of dietary fat. Most users buying R² Day standalone are restocking after running through their combined-box Day supply, or evaluating whether the daytime formula suits them before committing to the full system. Some customers report sustained-energy changes (fewer afternoon crashes) within 2–3 weeks of consistent use; the effect is subtler than caffeine and works on a different mechanism, so don't expect a sudden lift.

Frequently Asked Questions

Can I take R² Day without R² Night?
Yes. R² Day works independently for daytime cellular energy support. You won't get the overnight purification benefits the Night formula delivers, but the Day formula functions on its own.

Is this the same product that comes in the combined R² box?
Yes — identical formula. The standalone R² Day is the same Cordyceps Cs-4 / pomegranate / chokeberry capsule that ships in the combined R² box. The standalone exists for restocks and single-formula trials.

When should I take it?
With breakfast or a morning meal that contains some dietary fat. Take it consistently at roughly the same time each day — Cordyceps and the polyphenol blend work cumulatively, not as an acute hit.

Is R² Day a stimulant?
No. There's no caffeine or central nervous system stimulant in R² Day. The actives support cellular energy production at the mitochondrial level, which is a slower, subtler mechanism than stimulation. You shouldn't experience jitters, crashes, or sleep disruption.

Works With

R² Night — the overnight half of the system. Run them together for the full circadian protocol. The combined R² box bundles both at AU$155 (saves around AU$21 vs separate purchase).
