Arkas High Polyphenol EVOO: The Complete Guide for Singapore

This is the reference guide for everything you need to know about Arkas High Polyphenol EVOO — what it is, what it contains, what the research explores, how to take it, how to store it in Singapore, and how it fits alongside other supplements in a daily routine.

It is also the closing post of a ten-part series published by RealFUEL+ on high polyphenol olive oil — one of the most comprehensive English-language resources on this topic written specifically for the Singapore market.

Every section below links to the deeper post in the series for readers who want the full science. For those who want the essentials in one place, everything you need is here.

What Is Arkas High Polyphenol EVOO?

Arkas is a high-polyphenol extra virgin olive oil produced by Arkas Cooperative from the Olympia variety, cold-pressed from early-harvest olives in Olympia, Greece. It is designed to be taken daily as a high-polyphenol food-based wellness oil — not used as a cooking oil.

What distinguishes Arkas from standard supermarket olive oil is polyphenol concentration. Standard culinary EVOOs typically contain 50–150mg/kg of total polyphenols. Arkas is supported by producer-provided laboratory testing showing more than 800mg/kg total polyphenols — five to sixteen times more than the many standard culinary EVOOs commonly found in supermarkets, and more than three times the minimum concentration threshold set by EU Commission Regulation No 432/2012 for the authorised olive oil health claim. Certificate of Analysis available on request.

Arkas has been produced since 1972. It is available exclusively in Singapore through RealFUEL+ (realfuelplus.com).

The Five Active Compounds

Every serving of Arkas delivers five bioactive phenolic compounds that have been studied in peer-reviewed research. Here is what each one is — in plain language.

1. Hydroxytyrosol

Hydroxytyrosol is the compound at the centre of the EU-authorised health claim for olive oil polyphenols. It is the primary antioxidant phenol in olive oil — a water-soluble compound that research has explored for its activity in protecting blood lipids from oxidative stress. It is absorbed rapidly in the small intestine, reaches peak plasma concentration within 60–90 minutes of intake, and clears the system within 24 hours — which is why daily consistency matters more than periodic larger doses.

2. Oleocanthal

Oleocanthal is the compound responsible for the characteristic peppery throat burn you feel when taking Arkas. It was identified in a landmark 2005 study published in Nature (Beauchamp et al.) as having activity on the same COX-1 and COX-2 enzymes as ibuprofen. The peppery throat sensation is commonly associated with oleocanthal-rich EVOO. It can be a useful sensory cue, but it should not be treated as a precise measurement of total polyphenol content or clinical effect.

3. Oleacein

Oleacein has been described in research as one of the strongest inhibitors of 5-lipoxygenase (5-LOX) — an enzyme associated with early-stage inflammatory processes — with activity studied at levels stronger than oleocanthal and oleuropein at equivalent doses. Research has also explored oleacein in the context of cardiovascular and cellular protection. These are research findings — not approved health claims for this product.

4. Ligustroside Aglycone

Ligustroside aglycone is a secoiridoid compound — one of the structurally complex phenolic molecules found in early-harvest olive oil. It has been studied in research for enzyme-inhibitory activity. It is present in Arkas as part of the complete phenolic profile of the Olympia variety at early harvest — it is not an isolated extract but a naturally occurring component of the oil.

5. Oleuropein Aglycone

Oleuropein aglycone is among the most studied phenolic compounds in olive oil research. It is the aglycone form of oleuropein — the most abundant polyphenol in fresh olives — produced through enzymatic breakdown during the pressing process. Research has explored oleuropein aglycone across multiple areas including cardiovascular, metabolic, and cognitive health contexts. These are early-stage and preclinical findings in many cases — they are not approved health claims and should not be read as such.

The EU-Authorised Health Claim

Under EU Commission Regulation (EU) No 432/2012 — the official register of permitted health claims for foods — the following claim is authorised for qualifying olive oil:

"Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress."

This claim applies when olive oil contains at least 5mg of hydroxytyrosol and its derivatives per 20g of oil. At more than 800mg/kg total polyphenols, Arkas's concentration exceeds the EU minimum threshold — meaning the oil qualifies for this authorised health claim based on its concentration.

This is the only EU-authorised health claim applicable to olive oil polyphenols. It addresses one specific mechanism — the protection of blood lipids from oxidative stress. It does not extend to gut health, cognitive function, longevity, or disease prevention. All other research discussed in this series is shared as scientific context and educational information — not as authorised claims for this product.

How to Take Arkas EVOO

How much:  One teaspoon — approximately 5ml — is the RealFUEL+ daily starter protocol. Arkas packaging states a recommended daily intake of 12ml.

The EU health claim is established at 20g of olive oil daily. Due to Arkas's high polyphenol concentration, a smaller daily serving delivers a meaningful polyphenol intake as part of a consistent daily wellness habit. Consult your doctor for guidance specific to your health circumstances.

When: First thing in the morning, on an empty stomach, before food and before coffee. Research suggests a clear digestive tract is associated with a more favourable polyphenol absorption window — competing food matrices including proteins, fibres, and other fats may reduce absorption.

How: Straight from a teaspoon. Cold — never heated. Arkas is a supplement, not a cooking oil. Heat degrades polyphenol content significantly and should be avoided entirely.

What to expect: A peppery, slightly bitter sensation in the throat — this is oleocanthal confirming its presence at active levels. It is normal. It moderates with familiarity over the first two weeks but should not disappear entirely in a fresh, correctly stored bottle.

The commitment: The 90-Day Challenge — three consecutive bottles, one teaspoon daily — is the research-informed commitment window. The clinical studies most relevant to polyphenol supplementation run at 12–16 weeks. Thirty days is the first checkpoint. Ninety days is where the research picture is most complete.

How to Store Arkas EVOO in Singapore

Where: Cool, ventilated shelf or cupboard — away from direct heat and sunlight.

Away from: Stove, oven, direct sunlight, hot cabinets above cooking appliances, warm kitchen benches.

Fridge: Not required. Not recommended. Cold temperatures cause the oil to solidify and turn cloudy — harmless, but misleading. A cool, shaded shelf is sufficient.

Freezer: Not advisable. Not necessary for a 30-day consumption window.

After each use: Cap firmly sealed immediately. Do not leave open.

Consumption window: One 150ml bottle at 5ml daily = 30 days. Consume within 30 days of opening for best polyphenol retention.

Activity check: The peppery throat burn is the sensory indicator of active polyphenol content. A significantly reduced or absent burn on an unfinished bottle — check storage conditions and consider replacing.

How Arkas Fits Alongside Fish Oil

Arkas EVOO and fish oil are not competing supplements. They address different biological mechanisms through different compound classes and carry separate EU-authorised health claims.

Fish oil provides EPA and DHA omega-3 fatty acids — studied for triglyceride support and normal cardiac function. Arkas provides polyphenols — associated with the protection of blood lipids from oxidative stress. One works on the composition of blood fats. The other addresses the protection of those fats from oxidative damage. Neither substitutes for the other.

Arkas is also primarily an omega-9 oil — oleic acid makes up approximately 70–80% of its fat profile. Fish oil contains no polyphenols. Olive oil contains no meaningful EPA or DHA. They are different products serving different roles in a daily routine.

Anyone on anticoagulant medication should consult their doctor before taking either supplement.

Who Is Arkas For?

Arkas is designed for people who want to include a high-polyphenol EVOO in a consistent daily wellness habit. That includes:

Singapore adults of all ages — oxidative stress accumulation is a universal biological process, not exclusive to athletes or older adults. The Healthier SG preventive health framework supports daily wellness habits across all age groups.

Endurance athletes and active individuals — training in Singapore's heat and humidity generates an elevated oxidative stress load. Consistent polyphenol intake is one dietary input studied in relation to that load.

Adults managing long-term wellness — by 2030, one in four Singaporeans will be aged 65 and above. Mediterranean dietary patterns — which include consistent olive oil consumption — are among the most studied in healthy aging nutrition research. Polyphenol concentration is one variable researchers are beginning to examine within that broader research context.

Whether Arkas is appropriate for your specific circumstances is a conversation for your doctor.

Frequently Asked Questions

What is Arkas High Polyphenol EVOO?

A: Arkas is a high-polyphenol extra virgin olive oil from the Olympia variety, produced in Olympia, Greece, and designed to be taken daily as a wellness supplement — not a cooking oil. It is supported by producer-provided laboratory testing showing more than 800mg/kg total polyphenols, qualifies for the EU 432/2012 authorised health claim, and contains five bioactive phenolic compounds: hydroxytyrosol, oleocanthal, oleacein, ligustroside aglycone, and oleuropein aglycone. Available exclusively in Singapore through RealFUEL+.

What is the EU health claim for olive oil polyphenols?

A: Under EU Commission Regulation No 432/2012, the authorised claim is: "Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress." This claim applies when olive oil contains at least 5mg of hydroxytyrosol and its derivatives per 20g of oil.

At more than 800mg/kg total polyphenols, Arkas sits well above the commonly referenced concentration level associated with this EU claim framework, based on producer-provided laboratory testing. This is the only EU-authorised health claim applicable to olive oil polyphenols — it does not extend to gut health, cognitive function, longevity, or disease prevention.

How do I take Arkas EVOO?

A: One teaspoon (approximately 5ml) on an empty stomach, first thing in the morning before food and coffee. Take it cold — never heated. The RealFUEL+ starter protocol is one teaspoon daily. Arkas packaging states a recommended daily intake of 12ml. The 90-Day Challenge — three consecutive bottles — is the research-informed commitment window. Consult your doctor for guidance specific to your health circumstances.

How do I store Arkas EVOO in Singapore?

A: Store in a cool, ventilated spot away from direct heat and sunlight — a shaded shelf or cupboard away from cooking appliances. Refrigeration is not required and not recommended. Freezing is not advisable. Cap firmly sealed after every use. Consume within 30 days of opening at the 5ml daily protocol for best polyphenol retention.

Is Arkas EVOO the same as fish oil?

A: No — they address entirely different biological mechanisms. Fish oil provides EPA and DHA omega-3 fatty acids associated with triglyceride support and normal cardiac function. Arkas provides polyphenols associated with the protection of blood lipids from oxidative stress. They are complementary daily wellness product in a daily routine, not alternatives to each other. Arkas is primarily an omega-9 oil — it contains no meaningful EPA or DHA. Fish oil contains no polyphenols.

Where can I buy Arkas EVOO in Singapore?

A: Arkas High Polyphenol EVOO is available exclusively in Singapore through RealFUEL+ at realfuelplus.com. Standard supermarket EVOOs in Singapore — typically 50–150mg/kg total polyphenols — do not meet the EU minimum concentration threshold for the authorised health claim and are culinary-grade oils, not supplement-grade.
