Frequently Asked Questions
Common questions about N-Rex Tablets
What are the authorised claims for N-Rex?
They come from the vitamin B12: contributing to normal psychological function, to the normal functioning of the nervous system, and to the reduction of tiredness and fatigue. Each tablet provides 40µg of B12, which is 1600% of the NRV.
What do the ginkgo, ginseng and bacopa contribute?
They're the botanical part of the formulation — 120mg ginkgo biloba, 100mg ginseng and 35mg bacopa per tablet. Health claims for botanicals are held under review in the UK and EU, so we can't attach specific benefits to them and don't try to.
How quickly will I notice a difference?
Cognitive and energy effects from nutrient supplementation are gradual and subtle rather than immediate. Give it several weeks of consistent daily use. If you're expecting something you'll feel within an hour, this isn't that kind of product.
Can I take N-Rex with blood-thinning medication?
Speak to your GP or pharmacist first. Ginkgo biloba can affect blood clotting and may interact with warfarin, clopidogrel, aspirin and similar medicines. Stop taking it well before any planned surgery, and mention it to your surgical team.
Is it suitable for vegetarians or vegans?
The tablet uses a plant-derived hydroxypropyl methylcellulose coating rather than gelatin, so it is suitable for vegetarians. If you follow a strictly vegan diet, contact us and we'll confirm the current specification with the manufacturer before you order.
Is 1600% NRV of B12 too much?
B12 is water-soluble and has no established upper safe level, because the body absorbs a limited amount and excretes the rest. High-percentage B12 figures are normal in supplements and reflect how small the reference value is rather than an unusually large dose.
How should I take it?
One tablet daily with a meal.
