Dr Dolittle, Autism and the Broccoli Sprouts

In the Dr Dolittle books and subsequent films, a man develops the power to communicate with animals.  It seems that one effect of broccoli sprout powder (and we assume Sulforaphane), in autism,  is an urge to talk, not only to humans, but also to animals.

Monty, aged 11 with ASD, took his first dose of 2.5ml of broccoli powder (Supersprouts brand from Australia) and after about half an hour developed euphoria.  The laughter later subsided and throughout the day he was very talkative.  This was relevant speech and not repeating things he had heard previously.  Other than the euphoria, which is the word chosen by elder brother Ted, a nice development was the desire to communicate with the animal world.

After a visit to his favourite ice cream shop, he looked up and saw the big railway bridge. “Bye bye railway station” commented Monty.  Walking up the hill we first passed a kitten, playing by the verge, “Hello baby kitten! Bye bye baby kitten!”  Then a big dog appeared “Hello big white dog and a woman! Bye bye big white dog and woman!”.  This was all rather unexpected.

The next day, another 2.5ml of broccoli powder and the same result.  Euphoria and lots of talking.

Then I decided to start experimenting with the dose.  I gave 1.25ml three times a day.

After the breakfast dose, no euphoria but still plenty of speech.  After lunch, the second dose and the return of mild euphoria.  After the evening dose, more euphoria.  The half-life of Sulforaphane in people is claimed to be about two hours.

Based on this limited experience, I think 2.5ml is about right.  There is no need for more.


I paid AU$ 110 (US$ 95 or GBP 60) for 300g of broccoli powder including shipping.

2.5ml of powder weighs 1.1g.  So using that daily dose of 2.5ml the cost would be 35 US cents (22 UK pence).

My earlier assumption was that a dose of about 18 g of fresh sprouts would produce the required level of Sulforaphane.  In theory, this would be 3 ml of broccoli powder, if it had 100% of the right enzymes in it and none of the bad stuff (called ESP, from the last post).  I was quite surprised at the effect of 2.5ml.  Johns Hopkins told me that most broccoli powders are no good; that is why I looked around before choosing the Australian product.

As a dosage comparison, this supplement is sold in Australia with a suggested daily dose of 5g, which equates to about 11 ml. 

So my “autism dose" looks quite conservative.  I think even half the suggested adult dose would make Monty completely hyper.

Note that the dose of the anti-oxidant NAC used in autism trials is 4X the usual adult dose of NAC and 2X the adult dose for adults with COPD (severe asthma).

The effect on an adult

I tried a scaled up dose myself, but sadly no euphoria followed.

Monty is already taking a potent anti-oxidant called NAC, which has been investigated in an autism trial at Stanford.
The broccoli sprouts produce a substance called Sulforaphane (SFN).  This substance activates Nrf2 which upregulates “phase II enzymes”; they increase the body’s antioxidant response.  SFN is also an inhibitor of HDAC (Histone Deacetylase) and this may give SFN the ability to target aberrant epigenetic patterns.
SFN is therefore a secondary anti-oxidant.  It has been shown to improve the body’s response to cancer and environmental toxins.  The chemoprotective properties may result from SFN’s epigenetic properties or the anti-oxidant properties.
SFN was shown in a recent study at Johns Hopkins to improve autism in young adults.  It is not known definitively why it was effective.

My experiment indicates that, in classic autism, Sulforaphane (SFN) does provide a marked and immediate benefit over NAC alone, which is what I set out to determine.

Australian broccoli sprout powder appears to be a relatively cheap and effective way to make SFN at home.
