There is no such thing as a good proof nutrient drink being offered on-line within the UK to “assist” folks with early Alzheimer’s really slows the illness, say consultants.
Newest trial leads to sufferers who took Souvenaid didn’t discover it preserves reminiscence and pondering.
The authors say in Lancet Neurology that larger research are wanted to point out if the product can work as hoped.
And shoppers needs to be conscious that the £three.49 per bottle drink “isn’t a remedy”.
Producer Nutricia says its drink ought to solely be taken underneath the course of a health care provider, specialist nurse or pharmacist.
What’s the drink?

Taken as soon as every day, the thought is that the enhance of vitamins it gives will assist preserve Alzheimer’s at bay in folks with the earliest indicators of one of these dementia.
However the newest section two scientific trial outcomes don’t show this.
What the trial discovered
The examine concerned 311 sufferers with very early Alzheimer’s or gentle cognitive impairment. All of them have been requested to take a every day drink, however solely half got Souvenaid – the opposite half obtained one with no added vitamins.
After two years of taking part, the sufferers have been reassessed to see if there was any distinction between the 2 teams when it comes to dementia development, measured by varied reminiscence and cognitive assessments.
The therapy didn’t seem to supply a bonus, though sufferers within the Souvenaid group did have barely much less mind shrinkage on scans, which the researchers say is promising as a result of shrinkage in mind areas controlling reminiscence is seen with worsening dementia.
However consultants stay cautious.
