CELLULAR ENERGY AND ANTIOXIDANTS

Your cells need energy.
And protection from oxidation.

NAD+ helps your cells turn nutrients from food into energy. Quercetin and resveratrol are plant compounds with antioxidant properties.

What does an antioxidant do? It neutralizes free radicals: reactive molecules that can damage cells when they build up. That is the antioxidant function, explained simply.

NAD+ FortCore brings these three ingredients together in one formula: NAD+ for its role in cellular energy, alongside quercetin and resveratrol for their antioxidant properties.

Include it in your daily care with 2 capsules a day, following the label directions, alongside a varied diet, movement and rest.

See ingredients and amounts →
01 / NAD+

Turns nutrients into energy.

NAD+ takes part in the reactions that let your cells use energy from what you eat. It is a molecule naturally present in your body.

02 / QUERCETIN

A plant-based antioxidant.

Quercetin has antioxidant properties: it can neutralize free radicals. In this formula, it comes from an extract of the Sophora japonica plant.

03 / RESVERATROL

Another antioxidant in your formula.

Resveratrol also has antioxidant properties. FortCore includes it through a Japanese Knotweed extract containing 98% resveratrol.

CHOOSE WHAT YOU WANT TO KEEP DOING

Your plans deserve
a place in your routine.

Your goal is personal: your next trip, a favorite trail or an activity you want to return to. Use those reasons to turn daily care into concrete actions.

01

Get ready for your next trip.

You organize flights and accommodation, but leave finding time to walk and move before departure until last.

YOUR GOAL

Make room to explore on foot and enjoy a trip at your own pace.

YOUR FIRST STEPSet aside time for a short walk this week and note it in the guide. Adapt the route to your starting point and how you feel.

02

Return to an activity you love.

Between responsibilities, you’ve spent weeks putting off dancing, visiting the park or enjoying a favorite hobby.

WHAT YOU WANT TO GET BACK TO

A moment each week reserved for movement and doing something you enjoy.

YOUR FIRST STEPChoose an activity and give it a day and time. The guide includes options for moving at home when time is short.

03

YOUR FIRST STEPChoose one action for movement, one for food and one for rest. Use the 14-day tracker to find what is easiest to repeat.

Your cells use NAD+ to turn nutrients from food into usable energy. Think of it as a helper involved in that process. Your formula contains 500 mg per serving.

02 / Quercetin · A plant-based antioxidant

It is a plant compound with antioxidant properties. Antioxidants neutralize reactive molecules, called free radicals, that can damage cells. This formula provides 250 mg of quercetin extract per serving.

03 / Resveratrol · Another antioxidant ingredient

Resveratrol is an antioxidant found in some plants. In FortCore, it comes from Japanese Knotweed: each serving contains 150 mg of this extract, with 98% resveratrol. It completes the formula’s combination of plant-based ingredients.
