The Problem With Lactaid -- Aspgillus Mold

Rate this topic

Recommended Posts

In a recent thread Kathy (ksymonds84) posted about having a bad reaction to lactaid. By coincidence, I had just tried lactaid for the first time, and had a bad reaction each time -- near-instantaneous vomiting the second time. I checked the ingredients and saw nothing indicating gluten.

Wouldn't you know the answer is right here on the forum, in a thread from 2005. http://www.glutenfreeforum.com/lofiversion....php/t8147.html

Turns out lactaid (and other foods and enzymes) is made by using a mold called aspergillus. I wouldn't have immediately decided this was the villain, except that I took a B-vitamin a few days ago, had a bad reaction, and it turns out that yes, some vitamins are made with aspergillus. (Note: I've been gluten-free about 2.5 weeks, and have never had a bad reaction to this brand of B vitamins before.)

For more info, check the thread cited above. I'll also re-list the aspergillus-containing items from that thread:



CHOCOLATE that includes chocolate liquor






SOFT DRINKS (Citric acid is made with the aspergillus fermentation process)




ACIDOPHILUS WITH F.O.S. (Acidophilus has very healing effects and promotes natural anti-fungals in the body, however, artificially produced F.O.S. is made with the aspergillus fermentation process. If you would like natural F.O.S., you can consume watermelon seeds and reap the same nutritional benefits without any aspergillus fermentation).

Enzymes and what the enzymes are made of:*

Alpha-galactosidase ----- Aspergillus niger

Amylase ----- Bacillus subtilis, Bacillus amyloliquefaciens, Aspergillus oryzae, Aspergillus niger

Amylase ---- (Malt diastase) malt

Amyloglucosidase ---- Aspergillus niger, Rhizopus oryzae

Beta-amylase ---- wheat, Bacillus spp.

Catalase --- Aspergillus niger

Cellulase --- Aspergillus niger, Trichoderma longibrachiatum (reesei)

Glucose oxidase ---- Aspergillus niger

Hemicellulase ---- Aspergillus niger, Trichoderma longibrachiatum (reesei), Aspergillus oryzae, Bacillus subtilis

Lactase ---- Aspergillus oryzae, Kluveromyces lactis

Lipase ---- Aspergillus niger, Arthrobacter ureafaciens, Candida cylindracea, Rhizomucor miehei, Rhizopus oryzae, Rhizopus delemar

Lysophospholipase ---- Aspergillus niger

Pectinase ---- Aspergillus niger, Aspergillus japonicus, Rhizopus oryzae

Phytase ---- Aspergillus niger

Protease, microbial ---- spergillus oryzae, Aspergillus niger, Aspergillus melleus, Bacillus licheniformis, Bacillus subtilis, Bacillus thermoproteolyticus, Rhizopus niveus

revision 1/99

Beano was also mentioned.

Here are some links the original poster referred to:



Purely in the interest of science (har har), right now I'm testing whether I now react to chocolate liquor (which I confirmed is in my favorite Ritter Sport Marzipan bar).

A big thank you to Stephanie (skbird), who originally posted all of that incredibly useful information.

so is this mold harmful to the body, or just causing sensitivity to some people? i've taken lactaid on and off for a few months, and don't seem to have a problem with it.

No, it's only harmful to people who have an allergy or sensitivity.

I didn't know I had one until after being gluten-free for a couple of weeks. I guess this is part of the phenomenon others have also noticed, of becoming more sensitive after going off gluten. I wonder what that's all about.

    • It sounds like your hives resolved.  I had a six month bout with them.  Antihistamines really helped.  My doctors are not sure if Mast Cell or autoimmune is the root cause.  
    • My kid has Raynauds.  It freaks her classmates out.  She wears shoes and wool socks all year round and we live in a warm state.  It is autoimmune.  She manages it by layering, turning up the heat, use lots of blanket throws.   I have Hashimoto’s and celiac disease.  So, having multiple autoimmune issues is common.  
    • Well, you do need to replace some things because they are too porous or damaged to remove gluten.  Things like old wooden spoons, scratched non-stick pans, toaster, colander, sponges, etc.  Honestly, the list is long, so try getting a few celiac books at the library or Amazon.  Consider reading through the Newbie 101 thread under the “Coping section”.    You should see some minor improvement soon.  It does take time to heal.  Most  around here will say it takes a year!  
    •   When I woke up from my Endoscopy and was told I definitely had celiac disease the first thing I asked my doctor was do I need to get all new kitchen stuff? He assured me that I did not, and as long as my pots and pans and everything else was washed after being used to cook gluten I would have no problems. Well, I'm 10 weeks into my gluten-free diet and still feeling crappy as ever.  I have not been eating out unless the restaurant is 100% gluten-free (I'm lucky there are several near me).  I am very careful that everything I use to cook my food is thoroughly cleaned at home, but is this really enough?  Did you guys need to replace most kitchenware in order really avoid being cross contaminated?   I'm curious to get some opinions before I spend a bunch of money on new/separate stuff.  Thanks!  
    • They have all given you good advice. Like Ennis_Tx said this is not medical advice. Just some observations. Ennis_Tx mentioned already a good B-complex. But people who have Perncious Anemia low B-12 have "Pens and Needles' feeling in their extremities. Mine was much more pronounced when sleeping. . . while sleeping my nerve ending would go to sleep. This would wake me from my sleep.  I would shake them awake/loose much like a leg that had fallen asleep while awake.  We have all felt that feeling before except the whole side of body's nerve ending would tingle/fall asleep enough to wake me from my sleep. Once taking a homocysteine tablet (B6,b12 and folic acid) tablet call FABB for the abbreviated ingredients under doctor's supervision this "pens and needles' went away. This also happened in my finger and toe tips while awake as if I had pinched a nerve in my back. These sensations are now in remission. Also if you think it is Rynaud's then try Niacin or Niacinamide.  It is a natural vasodialotor and the 'warm sensation" people take when using Niacin especially in a work out supplement is Niacin they add to enhance athletic performance for body builders.. . . because this opens capillaries approx. 10 % more allowing more air into the muscles thus improving their work out. This flushing goes away after a couple days of using Niacin.  The Niacinamide form does not flush the way the Niacin form does but provides the same benefit. Both Niacinamide and Magnesium each lower blood pressure approx. 10% each this way.  But if BP is a real problem for you  take the Homocysteine tablet mentioned above or just Folic Acid by itself. My BP is now normal after taking Folic Acid because it controls' how/what triggers constriction in our blood vessels thus effectively controlling BP. These are some times that I have used to improve my circulation. *** again this is not medical advice just things that have helped me with similar issues.  I hope this is helpful. 2 Tim 2:7 “Consider what I say; and the Lord give thee understanding in all things” this included. posterboy by the grace of God,
