Nutriop® Pterostilbene Extreme — Advanced Cellular Defence. 4x Greater Absorption.

Swiss Formulated · 99% Pure Trans-Pterostilbene · 400mg Active Payload · Dual-Action Complex · 45-Day Supply

A premium, high-absorption longevity protocol engineered to activate SIRT1 (the body's longevity gene) and protect cellular health. This dual-action complex pairs clinical-grade Trans-Pterostilbene with Organic Grape Seed Extract to deliver superior bioavailability and comprehensive cardiometabolic support.

 


✦ The Bioavailability Advantage

While Resveratrol is widely known in the anti-ageing space, its biological cousin Pterostilbene offers a massive structural advantage. Due to its unique methylated structure, Pterostilbene is up to 4x more bioavailable and has a significantly longer half-life in the bloodstream.

This means a much higher concentration of active polyphenols actually reaches your cells — and crosses the blood-brain barrier to trigger deep cellular defence.

 


✦ The Smart Synergy — Why We Added Grape Seed Extract

While Pterostilbene is a highly effective cellular protectant, clinical studies show that high doses taken alone can occasionally impact LDL cholesterol levels.

We solved this by formulating Pterostilbene Extreme with an equal 1:1 ratio of Organic Grape Seed Extract — rich in oligomeric proanthocyanidins (OPCs). This provides potent cardiovascular support, helping to maintain healthy lipid profiles and offsetting the potential LDL effect.

A complete, balanced protocol — not just a single compound.

 


✦ Core Longevity Benefits

 

● SIRT1 Gene Activation

Triggers the body's natural longevity pathways associated with healthy ageing, cellular resilience, and DNA protection.

 

● Advanced Neuroprotection

Highly lipophilic (fat-soluble), Pterostilbene easily crosses the blood-brain barrier to support memory, focus, and healthy brain ageing.

 

● Cardiometabolic Health

The synergistic addition of Grape Seed Extract supports healthy blood flow, vascular elasticity, and cholesterol balance.

 

● Deep Antioxidant Defence

Neutralises free radicals and helps protect cellular machinery from age-related oxidative stress.

 


✦ The Nutriop® Purity Standard

Our formula uses 99% pure Trans-Pterostilbene — the most stable and active form of the molecule. Housed in 100% vegan Pullulan (fermented tapioca) capsules. Independently lab-tested for verified purity.

Free from: Artificial fillers · Soy · Gluten · Yeast · Synthetic additives

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!
