Souvenaid: I’m worried about my memory – should I buy this drink?

Our research team examined evidence on the nutritional drink Souvenaid, that was claimed to help improve some aspects of memory in people who have mild cognitive impairment.

Why is Souvenaid in the news?

In recent years, news outlets have reported on a nutritional, liquid dietary supplement called Souvenaid that claimed to 'stop the brain from shrinking' and 'slow the progression of Alzheimer’s disease.' This news coverage followed publications of the results of a trial known as ‘LipiDiDiet’.

Researchers followed a group of people who drank Souvenaid daily. They then compared their memory and thinking skills and changes to their brains with a group of people who drank a dummy drink.

People involved in the trial all had mild cognitive impairment (MCI), which is a condition where someone has mild memory problems that are not severe enough for them to be diagnosed with dementia.

Results to date have been mixed. After two years the trial failed to show a slowing in decline of thinking and memory skills in people with mild cognitive impairment. After three years, in a very small group of people who continued on in the trial, showed some encouraging signs of slowing the decline in memory and thinking skills.

From these results published so far, we cannot be sure whether Souvenaid provides a benefit for people with mild cognitive impairment.

People who are worried about their memory should not rush out and buy this drink but arrange to speak to your doctor. They can assess your memory and offer advice and support.

The results of this trial suggest further investigation may be warranted, but we will need to see the effects of the drink assessed in much larger groups of people with mild cognitive impairment before we will know if it might have a real benefit.

What is the Souvenaid drink made from?

Souvenaid is a medical drink containing an active ingredient called Fortasyn Connect. This is a combination of fatty acids, vitamins and other nutrients. It was developed with the aim of preventing the loss of important connections between brain cells that occurs in Alzheimer’s disease.

Whilst this effect on brain cells has been shown in some animal studies, it has not yet been confirmed that the drink has the same effect in people.

The drink is approved as a food for medical purposes for people in the earlier stages of the condition.

As it is a medical drink, it should not be purchased without first consulting your doctor or memory clinic about whether it is right for you.

What happened in the trial and what were the results?

The study involved 311 people who had mild cognitive impairment. They had tests, such as brain scans or spinal taps (also known as lumbar punctures), to show that their memory problems were most likely due to the very early stages of Alzheimer’s disease.

Half of the people on the trial took the drink containing Fortasyn Connect once a day for two years. The other half took a drink with the same calorie content but without the active ingredient. 

After two years the researchers analysed the results and there was no difference in the number of people who progressed from mild cognitive impairment to dementia. 

There was also no difference in scores in a specific series of memory and thinking tests. Brain scans from the trial did however show that the people who took Souvenaid had less shrinkage in certain areas of their brain, including in the hippocampus, which is involved in memory.

A small number of people continued on in the trial for an additional year. Results from this small group showed a slowing in decline of thinking and memory skills and again less shrinkage in certain areas of the brain, in the group who took Souvenaid compared to the dummy drink.

What do these trial results mean?

From the results published so far, we cannot say that the drink is able to prevent cognitive decline in those with mild cognitive impairment due to the very early stages of Alzheimer’s disease. 

Results after three years, although more encouraging were in a small group of people (approximately 80) with mild cognitive impairment. Before we can be sure if there is a benefit from drinking Souvenaid, we will need to see it tested rigorously in a much larger group of people.

Although the results of this investigation are not clear, there are steps we can all take to reduce our risk of dementia such as keeping physically active, not smoking or drinking excessively and eating a healthy balanced diet. It’s never too late to start. 

What does Alzheimer's Society think?

Commenting on results published in 2020, Hannah Churchill Research Communications Manager, said:

'Although this nutritional drink is unlikely to have a negative impact, the latest results from this study must be considered in context. 

'New results show less cognitive decline in a small number of people with mild memory problems who consumed the drink daily for three years.

Although this is good news and warrants further investigation, a more expansive study with more people must be conducted before we can be sure benefits of this drink are proven.

'Rather than rushing out to buy this product to combat memory problems or worrying symptoms, we would urge that anyone who is concerned about their memory to speak with their GP in the first instance.
'There are steps we can all take to reduce our risk of dementia and it’s never too late to start. Keeping physically active, eating a well-balanced diet and looking after your overall health are key.'

My husband diagnosed with vascular dementia. Several strokes. He is on Aricept but is declining. I bought the Souvenaid at chemist yesterday for myself. Still reasonable good cognitive.. Age 74. But I will give it a try for myself. Eating well, exercise and taking supplements. This is a terrible disease.
It's almost 3 years since your analysis. Could you please update ? I have noticed ads on radio that " studies show a 60% improvement over 3 years " can you confirm please? I would also like to know the key ingredient(s )
My husband is 69 and has early onset Alzheimer's. He has just started Souvenaid it will be interesting to see the impact if any in the future
Hi Mary, I was just wondering how your husband has been getting on after taking Souvenaid (My mother has been diagnosed in Fen and we started her on Souvenaid mid Feb)
Nigel I honestly dont know if it has made any difference. He will continue to take it. Its very expensive and can only be purchased over the Internet so alot of research to get the best price and free delivery. What's your thoughts?
Hi Mary, Thank you for the reply, I have been giving my mother (73) Souvenaid daily since the 17th April (early days yet), I sometimes think that she seems in better form and her symptoms seem to be somewhat under control albeit she has off days, I agree that the purchase price is expensive but I will continue to give it to her for at least 6 months to hopefully slow the progression. The reviews I have read to date on the most side seem to be positive enough so fingers crossed that it will be beneficial to both your husband and my mother. I have also recently been researching (Hyperbaric Oxygen Therapy) and the benefits it supposedly gives to Dementia patients,
Keep us posted please, would be delighted to hear how its all going.
Can you take this as a supplement even if you haven’t (yet) got any signs of cognitive decline ?

Hello Nell,

Please speak to your doctor before buying this drink. Your GP can offer further advice and help to answer questions you may have.

I am wondering aprt from the possible slowing of cognitive decline does this drink have nutritive qualities.
SUVENAID lf taken by an older person not yet showing signs of dementia but some slight memory changes can it be of help as a nutritional drink thank you Audrey White age 87 years
Self and wife 85 and 83 do not have the disease as yet but no doubt it will arrive so would appreciate details of current treatments if any. Thanks

I have question. Husband has PSP, this rare brain condition is caused by the Tau protein, but is part of the atypical parkinson family. .. Would this be worth a try... There is no specific treatment as yet. ??

Hello Debbie,

Thanks for your comment.

Our advice here would remain the same as in the above article. Although this nutritional drink is unlikely to have a negative impact, more research is needed to understand the causes of dementia. We would suggest that your husband speaks with their GP in the first instance.

We hope this helps,

Some things are likely to help most people: more exercise (both aerobic and resistance), less sugar and refined carbs, control blood sugar and blood pressure, etc. Diets higher in fruits and vegetables (with more fiber and polyphenols) are also good for just about everyone. Healthy fats like those in MCT oil, olive oil, fatty fish and grass-fed meat and butter are also likely to help most people.

The ingredients of the drink are listed as Omega 3 fatty acids (DHA EPA), choline, Vitamins C, E, B6 B9 B12, phospholipids, and uridine monophosphate. These sound unlikely to be harmful and likely to help some people.

But who, exactly, is likely to be helped by "talking to a physician" about his memory? The doctor will either tell you to do one or more of the above, or reassure you you can continue to do nothing.

My mother started taking Souvenaid daily 3 years ago after she was diagnosed by a geriatrician with early Alzheimers Disease at age 89. After taking the Souvenaide for 2-3 months, we noticed that she markedly improved in her memory, social skills & the amount of confusion she had been experiencing. She was also taking the medication Aricept. She has had amazing results. We (her 4 children) can't recommend it enough !!!! Try it with your loved one for at least 6 months, as I'm thinking the result would be different for different people. She loved the vanilla flavour. It has given both her and us 3 more years of quality time which we would never have had.

Hi we’re do you buy this tea at???

My mum suffers from dementia and l would like to try this drink from where can l buy it
Thank you x

I have been taking Suvenaid for 4 years and my dementia hasn't got any worse , so I have great faith in it,

Hi Pamela, May I ask how old you were when you were diagnosed and if the Suvenaid is still working for you,

My Mum has been on it for three years and if not taken we do notice a difference. I give her the vanilla. It's a horrible disease and we should be researching it more. Too many people are getting it. WHY

Re above question regarding Dementia::-I would say that the increased number of people who have dementia are a result of more people living longer! QED

Is this drink safe for someone who has had a kidney transplant? My mom is 78 and got a new kidney about 7 years ago. For the last year or so we’ve noticed signs of dementia. Thank you

Hi Brian, I'm very sorry to hear about your mom.
You should contact your mom's doctor with this question, we would always recommend asking a doctor first.

I live in Perth Australia my husband has alzimers, our Dr says none of the treatments available work. We are all getting older and could be susceptible to the disease its well before time that something is discovered.

I would give it a go if it cannot do you any harm.
