ageLOC® R² (R2) Day (UK)

For the Office Worker Who Sleeps Fine But Still Crashes at 3pm

You're getting seven or eight hours. You're not particularly stressed. Yet somewhere between lunch and the afternoon stand-up meeting, your concentration drops off a cliff. If that pattern sounds familiar — and it's especially common for desk workers grinding through centrally heated offices in Manchester, Leeds, or the City of London — it may be less about sleep quality and more about cellular energy production declining with age. ageLOC R² Day (£62.88) is the daytime component of Nu Skin's R² supplement system, formulated with Cordyceps sinensis Cs-4, pomegranate extract, and alpha lipoic acid to support mitochondrial efficiency during waking hours. It isn't a stimulant. It doesn't spike. It addresses what's happening at a cellular level, not just how you feel in the next 45 minutes.

Best suited for: Adults over 35 noticing age-related energy decline — adequate sleep, still flagging by mid-afternoon. Desk workers in air-conditioned or centrally heated environments. Caffeine-sensitive individuals. Those already using R² Night who need a standalone Day refill.

Less suited for: Under-35s seeking a quick energy spike. Pregnant or breastfeeding women. Those on immunosuppressant medication (consult your GP first).

Pairs well with: ageLOC R² Night (£59.90) — the full day-and-night system is available as the ageLOC R² pack (£109.00).

What Makes R² Day Different

Most energy supplements on the UK market — whether it's a Vitabiotics Wellman tablet or a caffeine-loaded pre-workout — address symptoms rather than the underlying mechanism. They give you a push. They don't address why the push is needed more frequently as you age.

The underlying issue is mitochondrial decline. Mitochondrial function decreases by roughly 8% per decade after age 30 (PLoS Biology, 2007), meaning the cells themselves become less efficient at producing ATP — the molecule your body uses for energy — regardless of how well you eat or sleep. R² Day targets this directly through three ingredients with distinct, complementary mechanisms.

What's Inside

Cordyceps sinensis Cs-4

A standardised medicinal mushroom extract — critically, the Cs-4 strain used in peer-reviewed clinical research, not a generic powdered whole-mushroom product. Cs-4 has been studied for its effects on ATP production and oxygen utilisation. A 12-week clinical trial in older adults demonstrated improved exercise performance and oxygen utilisation (Chen S, et al., Journal of Alternative and Complementary Medicine, 2010;16(5):585–590). The standardisation matters: many functional mushroom supplements sold through Holland & Barrett or similar UK retailers use whole-mycelium powder with no standardisation to active compounds, making dose and effect unpredictable.

Pomegranate Extract

Standardised for punicalagins and ellagic acid — not whole fruit powder, which varies substantially in active compound concentration. These are precursors to urolithin A, a metabolite shown to induce mitophagy: the cellular process of clearing out damaged mitochondria so healthier ones can function more effectively (Ryu D, et al., Nature Medicine, 2016;22(8):879–888, PMID: 27400265). Mitophagy is increasingly recognised as central to healthy cellular ageing.

Alpha Lipoic Acid

A dual-environment antioxidant — effective in both water-soluble and fat-soluble cellular compartments, unlike vitamin C (water-only) or vitamin E (fat-only). Alpha lipoic acid also functions as a cofactor in the pyruvate dehydrogenase complex, directly within the mitochondrial energy chain, and supports the recycling of vitamins C and E.

How to Use

Take 2 capsules in the morning with breakfast. Timing is intentional — R² Day is formulated for daytime metabolic patterns when mitochondrial energy demand is at its highest. Taking it in the evening is counterproductive to the system's design. Most users notice a difference in sustained afternoon alertness within 2–4 weeks of consistent daily use. The effect is characterised by steady focus rather than a spike — particularly useful during those grey British winter afternoons when the light is failing by 3:30pm and you'd normally be heading to the office kitchen for the third time.

For the complete mitochondrial support system, use alongside ageLOC R² Night (£59.90), which handles detoxification and cellular repair during sleep — available together in the ageLOC R² pack (£109.00).

Frequently Asked Questions

Does ageLOC R² Day ship to addresses across the UK, and how long does delivery take?

Yes. R² Day ships from the Nu Skin UK warehouse and typically arrives within 2–4 business days across mainland UK, including Scotland and Wales. Northern Ireland delivery times may vary slightly. No EU-based warehouse is used for UK orders — post-Brexit, all UK shipments are fulfilled domestically.

Do I need to buy the Night formula as well, or does R² Day work on its own?

R² Day provides meaningful standalone support for daytime energy and mitochondrial efficiency. However, the system is designed as a complementary day-and-night pair: the Night formula addresses cellular detoxification and repair during sleep, which complements the Day formula's energy focus. Purchasing both as the R² pack (£109.00) rather than separately (£62.88 + £59.90) reflects better value for those committing to the full protocol.

Is R² Day regulated as a food supplement in the UK? Does it need MHRA approval?

R² Day is classified as a food supplement under UK law, regulated by the Food Standards Agency (FSA) — not the MHRA, which oversees medicines and medical devices. Food supplements do not require pre-market approval from the MHRA but must comply with the UK Food Supplements Regulations 2003 and relevant labelling requirements. Nu Skin operates as a registered business in the UK.

How is this different from taking a B-vitamin complex or a multivitamin?

B-vitamins support energy metabolism as cofactors but do not directly address mitochondrial decline. R² Day uses Cordyceps Cs-4 and standardised pomegranate extract to target mitochondrial efficiency and mitophagy — a fundamentally different mechanism to adding more cofactor vitamins. If you're already using a comprehensive multivitamin such as LifePak+ (£79.90), additional B-vitamins are unlikely to make further impact. Addressing mitochondrial function operates on a separate pathway entirely.

I'm caffeine-sensitive — is R² Day safe to use?

Yes. R² Day contains no caffeine, guarana, taurine, or any stimulant compounds. The energy support mechanism is mitochondrial rather than adrenal — there is no jittery edge and no afternoon crash associated with its use. It is specifically suited to people who have found caffeinated products counterproductive or who are trying to reduce their reliance on coffee to get through the working day.

Can I take R² Day alongside other Nu Skin supplements such as LifePak+ or Marine Omega?

The R² system is designed to be compatible with Nu Skin's broader supplement range. Commonly paired with LifePak+ (£79.90) for comprehensive nutritional support and Marine Omega (£45.27) for cardiovascular and anti-inflammatory support. As with any supplement combination, if you're taking prescribed medications, check with your GP or pharmacist before adding new products — particularly if you are on immunosuppressant therapy, as Cordyceps has immunomodulatory properties.

What's the expected timeline before noticing a difference?

Most users notice a change in sustained afternoon energy within 2–4 weeks of consistent daily use. The effect builds progressively rather than appearing immediately, consistent with a mechanism working at the cellular level rather than through a stimulant response. Cellular mitophagy processes — the clearance and renewal of mitochondria — operate over weeks rather than hours.
