  • Improve working memory: Think Sharp enhances your ability to remember and process information, ensuring you stay sharp and focused.

Your brain's power starts to decline as early as age 45, and by the time you reach 60, this decline accelerates. Think Sharp aims to combat these challenges.

How does Think Sharp work? We've taken a comprehensive approach:

  • Brain Booster: Sibelius™: sage, bacopa, phosphatidyl l-serine, and huperzine work together to enhance accuracy, attention, working memory, and recognition.
  • Brain Protector: B vitamins and Folate safeguard your brain from age-related diseases and slow the rate of brain shrinkage.
  • Brain Cleaner: Our formula contains CyanthOx™ and Oxifend® to eliminate free radicals, keeping your brain healthy and functioning optimally.

Each ingredient in Think Sharp has been carefully chosen for its proven benefits.

Dementia is a rising concern, but Think Sharp is here to support your memory and brain health. We believe that while there might not be a cure, taking the right steps can make a significant difference. Don't let cognitive decline hold you back. Try Think Sharp today and unlock your brain's full potential.

How long will it take to work?

We're using an ingredient called Sibelius™:Sage, which starts to work within one hour of taking the supplement, so people should really feel an almost immediate boost to their thinking. The other ingredients are really designed to build up and provide cumulative benefits over a longer time frame so say within one month. Individual results may vary.

When should I take the product?

Take two capsules per day, either with or without food. We strongly recommend taking it during the day rather than just before going to sleep because the Sibelius™:Sage extract does kick in within the first hour. Most people want to be feeling sharp, good and on form during the day and rest their brain at night.

This product shares many benefits with Omega 3 fish oil. Which should I be taking?

We suggest you take both because they complement and reinforce each other because they work in slightly different ways.

We highly recommend everyone take DHA and our Xtendlife fish oil blends have a high content of it. There are some really good long-term studies showing that supplementation with DHA is protective against the development of dementia, but we haven't seen any studies published showing that taking DHA or any fish oil has an immediate and short-term effect on the sharpness of thinking.

Why are the doses of Sage in Think Sharp lower than those in some of the clinical trials?

Levels of Sibelius™:Sage in some trials are 333 mg and Think Sharp has 167mg; there are two reasons for this.

Firstly, Sibelius™:Sage and huperzine work by the same mechanism (they boost the levels of acetylcholine in the brain and body), so if we used both, the higher levels of Sage could end up doubling the impact and have potential side effects.

Secondly, a 167 milligrams daily dose of Sibelius™:Sage has still been clinically proven to improve working memory, speed of processing, memory recall and a number of other memory domains.

Is it safe to take sage long-term?

Yes, the only issue is Thujones which are present in Sibelius Sage. The upper limit for daily consumption of Thujones is 6mg per day. Sibelius™:Sage contains thujones at a very low level (not more than 0.1%). A daily dose of 167mg Sibelius™:Sage that's in Think Sharp would deliver 0.167mg thujones, which is well below the upper daily limit for this substance.

Can I give Think Sharp to children or pets?

Not suitable for those under 18 years of age. Not suitable for pets.

Does this product contain any allergens?

No, it doesn't contain any allergens.

Is Think Sharp suitable for vegans or vegetarians?

Yes, Think Sharp is suitable for both vegans and vegetarians.

Will this supplement interfere with prescription medications?

All supplements should be taken 2-3 hours away from prescription medication. We recommend checking with your doctor before beginning any supplement.

Can I take other Xtendlife supplements alongside Think Sharp?

Yes, you can. All our products are formulated to work synergistically with each other.

Can I take Think Sharp if I am pregnant or breastfeeding?

No, we do not recommend this. The only product we recommend during this time is our Omega 3/DHA fish oil, which has valuable properties to support both the health of the mother and baby. 
Fish oil is highly recommended by many medical professionals during pregnancy and breastfeeding to help support infant brain development, as well as systemic organ growth. It can also play a valuable role in supporting the post-natal mood and brain function of the mother. As the baby draws from the mother's precious stores of DHA, they can easily become depleted, therefore supporting levels with a supplement such as Omega 3/DHA fish oil is very wise.
