What You Need To Know About Lucidal

Lucidal is a nutritional supplement for your brain and it may work as described. It has been developed by a neurosurgeon called Dr McCleary and it has been clinically tested with results looking very promising although further research is needed. A major drawback is that it is quite expensive but if you are concerned about your mental performance and long-term brain health, it may be worth a try.

What Are The Side Effects Of Lucidal?

According to the clinical test the only side effects were mild nausea and headaches. However Lucidal may cause interactions with prescription drugs and alcohol.

How Much Does Lucidal Cost?

Lucidal is expensive. If you buy from the McCleary Science website, it costs $74.99 for a bottle of 90 capsules (one month’s supply). It is slightly cheaper from Amazon USA at $69.99 for 90 capsules.

Our Verdict On Lucidal

Lucidal is a nutritional supplement which may work as described and help increase concentration, memory and long-term mental health. It was developed by a neurosurgeon and it has undergone clinical testing so it certainly has the right credentials. We also like that it is safe to buy from the McCleary Science website with no dodgy billing issues along the way.

However it is important to err on the side of caution and remember that Lucidal is not yet strictly proven. The clinical trial advised that more research was necessary so you may find the effects are not as noticeable as you would like. The product information warns that the supplement may affect different people in different ways.

Finally, Lucidal is expensive and although we cannot count the cost of long-term mental health, this supplement may simply be beyond the budget of most people, especially if you take it long-term.

Lucidal Review

Lucidal is a nutritional supplement for your brain. It contains a wide range of vitamins, minerals and amino acids as well as some herbal ingredients such as green tea and maritime pine bark extract. All these ingredients are often present in other nootropic supplements but we have never seen them all together in this combination before.

We are usually concerned about supplements that contain numerous ingredients because it many cases they are untested in combination. However Lucidal has undergone clinical testing and results look very promising. Side effects are minimal and results suggest that Lucidal will enhance memory, focus and concentration and help treat mild depression and anxiety as the advertising claims.

Lucidal Facts

  • Each bottle contains 90 capsules or one month’s supply.
  • Nutritional supplement devised by a neurosurgeon.
  • Clinically tested supplements.

The ingredient quantities are not provided but the fact that Lucidal has been formulated by a neurosurgeon carries a lot of weight. In addition this formula has been clinically tested.

How to Take Lucidal

According to the product information, the human clinical trial subjects took three capsules in the morning. You are recommended to take with a meal. It may also be taken three times a day, or two pills at one time and one at another, or any combination of these. Sometimes the product is best taken an hour before a mentally taxing event, or when maximal effect is desired.

We investigated Dr Larry McCleary and found that he has had a long and illustrious career. Unlike many medically qualified people, he has an interest in nutrition as a potential cause for numerous diseases and brain health, using nutritional supplements as an aid for people recovering from surgery.

The company behind Lucidal is McCleary Scientific. The company develops, manufactures and sells targeted nutritional supplements based on Dr Larry McCleary’s work. As well as Lucidal, you can buy Bonexid – a nutritional supplement for bone health and Vitaloss – a supplement aimed at supporting healthy weight loss.

Lucidal Concerns:

  • Lucidal is expensive. Most people will not want to pay $79.00 a month for a supplement.
  • The clinical trial lasted 3 months. Will this supplement be safe to take long-term?
  • The Lucidal formula does require further clinical investigation according to experts.

Dr Larry McCleary is the author of books on health such as Feed Your Brain, Lose Your Belly and is well known to many people from his appearances on TV on various health shows such as Dr Oz.

You can buy the full range of products direct from the official website as well as outlets such as Amazon.

What Does Lucidal Claim To Do?

According to the product advertising, ‘Dr Larry McCleary’s brain-enhancing formulation Lucidal is a holistically designed, patented nutritional supplement for the brain that contains more than 50 ingredients. It represents the culmination of many years of work investigating the benefit of nutritional support on brain health.’

The way that this supplement works is explained too, Lucidal, ‘provides many brain-specific ingredients designed to work together to enhance nerve cell function, improve connectivity, speed up the rate at which brain cells communicate with each other, decrease the damaging effects of free radicals, slow brain atrophy (shrinkage), enhance mitochondrial function (the energy generating parts of the cells) and improve neurotransmitter function (such as acetylcholine – for memory and focus) and dopamine (for feeling good and being more focused).

The clinical testing into Lucidal was “shown to enhance focus and concentration in a sustained fashion, improving the type of learning that is used in education, and elevating mood, including assisting with mild depression and anxiety”.

Does Lucidal Work?

Yes, Lucidal does probably work to improve brain health but you might not notice instant effects. The clinical test ran for three months and seemed to benefit the 40 – 60 age groups according to results. However, the test did conclude that more research was necessary.

We can see that people may take this supplement in an attempt to stave off neurological disorders such as Alzheimer’s and Dementia as well as help improve current issues such as memory loss and mood.

According to the clinical test,

Supplementation with nutrients of the type evaluated in this study suggests that it provides a beneficial impact upon brain health. It is inexpensive, makes biological sense, is simple to administer and would be expected to benefit those most at risk: the poor, young, elderly and medically infirm.

The issue for many people will be the cost. This supplement is fairly expensive despite the fact that it could save money long term. There are no real guarantees that it will work as described.

What Are The Ingredients of Lucidal?

There are over 50 separate ingredients in this supplement. These are as follows:


  • Beta Carotene, Alpha Carotene, Lutein, Zeaxanthin, Cryptoxanthin, Gingko Biloba, Green Tea, Vinpocetine, Bilberry, Grape Seed, Maritime Pine Bark, Lycopene, Resveratrol: These ingredients are known for their antioxidant content. Antioxidants are molecules that can have a protective effect against aging and disease.


  • Choline, Inositol, Trimethylglycine: Antireductants decrease reductive stress and like antioxidants are important for their protective effects against free radical cells in the body.

Calcium Modulators

  • Taurine: Taurine is an amino acid type substance that can have a protective effect against heart attacks and strokes. It helps to keep calcium out of the muscular tissue of the heart. Taurine also protects against the damage associated with insulin resistance, the underlying cause of much hypertension, cardiovascular disease, abdominal obesity, and type II diabetes.

Cholinergic Neuromodulators

  • DMAE, Huperzine A: Substances that help the cholinergic system function. This is the network of chemical messengers and neurological pathways used by the brain and throughout the body.

Cellular Energisers

  • Creatine, Alpha Ketoglutarate, N-Acetyl L-Tyrosine, Acetyl L-Carnitine, PABA, Glutamine, L-Pyroglutamic Acid: These amino-acids strengthen cells and enhance energy production.
  • Phosphatidylserine: Chemical manufactured in the body and an important part of cell structure. It is taken as a supplement form because it may improve memory and thinking skills.

Glycosaminoglycans Modulators

  • Chondroitin, Glucosamine: These long unbranched polysaccharides often abbreviated as GAGS help maintain elasticity and collagen in the cells of the body. These are important for anti aging.

Insulin Sensitisers

  • Vanadium: Chemical element that may increase the effects of insulin.

Mitochondrial Cofactors

  • Acetyl L-Carnitine, Alpha Lipoic Acid, Coenzyme Q10: These amino acids help the way that the mitochondria – the organelles that inhabit the cells of the body, function. Mitochondria help the cells and therefore the body provides energy.


  • Soy isoflavones: Neurotrophins are proteins that help regulate the function of the nervous system.

Vitamins & Minerals
B12, thiamin, riboflavin, niacin, folate, biotin, pantothenic acid, magnesium, zinc, selenium, chromium and potassium.

Are There Any Customer Reviews For Lucidal?

There are a few customer reviews for Lucidal. Most opinions are positive.

This customer reported,

While, of course, it is somewhat subjective, I am certain Lucidal helps me with recall especially under pressure e.g. making a presentation.

Another customer feels that it has helped with a brain injury,

I have had several sports related concussions and have had a lot of trouble with memory, focus, etc. When I first discovered it, I took Lucidal for about a year and felt the best I have felt since the last concussion … after about a month, I feel calmer, more focused than before… I hope to be much better after taking them for about 6 months. However, I have to say that my sister didn’t really care for them … she felt that they made her more anxious than less. So my conclusion is that perhaps it is for people who have a history of head trauma or extreme stress, etc. I will personally be taking them as long as they sell them.

One customer was not as satisfied,

I consistently took the recommend dosage on a daily basis and noticed nothing! In my opinion, this product isn’t worth $10 for the entire bottle. I suggest you spend your money elsewhere.
