So where’s the stuff for us older folks, science? Got anything good in the bag for us to keep a good memory and stay energized? Fortunately, the answer is yes! Lumultra Wisdom by Avanse Nutraceuticals is a new product that has recently caught the attention of hundreds of seniors for its impressive formula and good pricing option. If you’d like to learn more about Wisdom and what benefits it can bring, check out our review!

Formula Highlights

Supplement Facts

Serving Size: 2 Capsules
Servings Per Container: 30

Clarity Blend 550 mg: Acetyl L-Carnitine, Bacopa Leaf Extract, CDP Choline

Vitality Blend 200 mg: Panax Ginseng, Oat Straw

Memory Blend 310 mg: Huperzine A, Noopept, L-Theanine, Ginkgo Biloba
Key Ingredients:

Acetyl L-Carnitine: ALCAR will make you feel less tired, more eager to get stuff done and essentially be less dependent on others to do everyday tasks. Using ALCAR consistently will also lead reduced brain fog, giving you the chance to think clearly and stay focused.

Oat Straw: Oat Straw is a herb that can reduce anxiety, improve sex drive, maintain bone health and enhance mental function in aspects such as attention and focus. Recently, a study has been conducted to test the effects of oat straw extract on elderly adults and the results showed an improvement in concentration abilities.

Noopept: Don’t ask us why but Noopept is probably the most underrated nootropic out there. Considering its effectiveness and potency, this nootropic deserves a lot more credit than it gets. But maybe that’s because not enough people know about it. Noopept is a compound designed back in the 1960’s as a brain booster. Its benefits include: improving memory, focus, alertness, mood and learning skills. The best part about Noopept is that it’s suitable for nearly anyone, including and especially those above 60. Noopept users are not only impressed by the compound’s ability to improving brain function but also it’s potential of boosting confidence and self-esteem.

Effects and Benefits

Our results with Wisdom were absolutely staggering. To be specific, memory recall was boosted well beyond the manufacturers claims – definitely a first! Wisdom users also reported feeling a higher sense of mental clarity and improved abilities to recall information. One user was very excited to realize that he could recall the names, phone numbers, and even addresses of people that he previously forgot about. Another user was impressed after seeing an improvement in verbal fluency and how she could recall complicated vocabulary words that she hadn’t used in a while. The last member said that Wisdom’s results were mostly prominent in energy levels – she didn’t feel as lethargic in the morning and was able to go to her aquatic aerobics class in the afternoon without feeling like it was a struggle.

Rating: 19/20

Potential Side Effects

We didn’t see any side effects during our trial and this may be the case due to the presence of CDP Choline in the formula – a nutrient that helps prevent side effects. However, if you try the product and don’t like the results then you can simply ask for a full refund by e-mailing the company.

Rating: 20/20

Pricing Options

On to the price of the product, which is an area that many people are concerned with when looking for a good nootropic supplement. Wisdom is definitely not overpriced so feel free to breathe and relax. The bottle, which you can order from Lumultra.com, is sold for $59.97 and will last one month.

Rating: 20/20

Online Reviews

You won’t be able to find very many consumer reviews on Lumultra Wisdom because the supplement has just recently been introduced to the market. Out of all the expert reviews that we found, however, we noticed a consistent praise on Wisdom’s potent formula and lack of side effects.

 Rating: 19/20

RECAP:

Positives

  • Boosts energy
  • Improves memory recall
  • Increases focus abilities

The Best Brain Supplements: Your Complete, Personalized Guide

In such a busy, harried world, people look for all the help they can get.

They’ve got problems remembering things, concentrating in school or focusing on a big work project, or being in the best energy and mood level for family and their personal goals.

Nootropics - also known as “smart pills” and brain enhancement supplements - are designed to help address these cognitive issues and improve memory and learning, focus and concentration, problem solving, and overall energy and vibrancy. These supplements are a potential fit for students (usually college students), professionals and business executives, and the elderly who want to enhance their brain power and performance.

Check the Best Smart Pills

The question, though, is…

Do you know the best brain-enhancing supplement for you?

Our product reviews will answer exactly this. By presenting accurate, up-to-date product information, conducting weeks-long product trial, and raising the alarm on fillers and low-quality ingredients, we’re about to guide you in your decision-making.

We take a long, hard look at the manufacturer, where they manufacture the pill, the website, pricing, customer testimonials, and different authoritative websites that point to how safe and effective a smart pill is.

At the end of it all, we present our Top 5 rated smart pills for your easy reference.

How Do Nootropics Work?

Known by many different names, nootropics act as brain enhancement aids and brain boosters that don’t leave your cognitive wellness to fate.

There are two kinds of nootropics: (1) pharmaceutical cognitive enhancers made up of chemicals believed to have a clear effect on the brain and nervous system, and (2) natural cognitive enhancers, which are mostly herbal or nutrient-based in their composition. Our reviews focus on the second group, which don’t require a prescription, not considered drugs, and thus are allowed to be sold the counter and online via vitamin retail shops like Amazon.

Are natural nootropics actually the savior they’re painted to be?

These plant-based extracts promise improved mental functioning, no less. Their surging popularity, particularly in recent years, can be attributed to their high overall safety value and few and minor side effects compared with their pharmaceutical counterparts.

If you’ve heard of the term “nootropic stack,” it means different herbal or nutrient-based nootropics “stacked” together to achieve your own cognitive targets.

Types of Natural Nootropics

  1. Neurotransmitter enhancers - These increase the activity of brain chemicals responsible for mental sharpness. Examples are acetylcholine, and other neurotransmitters.
  2. Vasodilators - Boost blood flow to the brain via widening the blood vessels.
  3. Antioxidants - Preserve and protect brain cells from the damage caused by free radicals roaming in the body

A high-quality nootropic can change your brain wellness and make you limitless in many different ways. These include enhanced memory, increased attention to detail, outrageously good focus, increased alertness, better mental and visual acuity, improved learning and thinking, managed stress, better mood and energy, and a generally renewed sense of life and brain performance.

This is why this product review guide will help you in so many ways to know a nootropic inside and out. From the ABCs of the product formula to the overall verdict, you will have an informed choice of what to choose for your next nootropic bottle or product.

What Should You Look For In A Top-Rated Nootropic?

  1. Offers essential vitamins and nutrients - Your brain gobbles up an unbelievable amount of vitamins, minerals, amino acids, and nutrients for it to properly function for life’s everyday demands. The nootropic you deserve provides these crucial components and more. Ginkgo biloba, Bacopa monnieri, Panax ginseng, and more - the list is endless, but only a few good ones deserve your attention. Click here for the top-rated ingredient list for a smart pill.

  2. Backed by clinical data and experts - The best nootropics have a solid scientific basis through independent, third-party research data on their effectiveness and benefits.

    There’s no reason for a credible health care expert not to endorse a well-created supplement for brain enhancement.

  3. Superior manufacturing standards - It’s not just about the ingredients, but also creating the product with the highest standards of production. The best supplements are manufactured in the United States, in a laboratory registered by the FDA. The manufacturer should be GMP certified as well!

  4. Independent reviews (Not just Amazon!) - Reviews can be bought and unverified, so keep an eye out for them. Our reviews, for instance, maintain their independence through a circle of product testers that really get to the bottom of things and assess individual product performance and quality.

What Should You Avoid In A Brain Enhancement Supplement?

  1. Improper dosage - Incorrect levels of each active ingredient - yikes! This leads you to believe that you’re getting optimum value and not the cheaper, over-hyped product that it actually is.

  2. Insufficient return policy and fraud - Reputablecompanies offer 100% money-back guarantee since they are confident enough that their product works. Read the fine print and don’t just trust what you see on the surface.

  3. “Free trial” offers - Does it seem too good to be true? Then it probably is. If you have to enter your credit card details to get to try a product for a month for free, then it’s not free.

Let’s combine your due diligence in research and our honest, in-your-face product reviews that won’t leave you guessing and wanting more information.
