Seeking Health Lactase Drops, Supports Lactose and Dairy Digestion, for Lactose-Intolerant, Lactase Enzyme in Sweet Natural Glycerin Base to Make Lactose-Free Milk, 52 Servings (0.50 fl. Ounce)

I started adding this to kefir (cultured milk) and it definitely makes it easier to digest. It also works for yogurt. The cost is less than buying the lactose free versions of kefir and yogurt, which are sometimes out of stock anyway. I didn't write a review until I'd used an entire bottle and purchased another one because I wanted to be certain that it made a difference.

Works great!

In my experience this product works.

These drops seem to make my glass or 2 of 1% a little more agreeable with my digestion. Going through a gallon a week, I'm a lifetime milk lover. But as the years pile up, there has been more minor stomach rumbling and other minor issues, assuming I've developed an intolerance over the years. Almost all the issues have settled way down since using these drops. I deducted a star because of the price..seems very high. But I need it. Will probably buy again.

It is very effective for high lactose food products.

I have purchased this product 12 times according to Amazon, and have never had a problem. Today, I opened the sealed SeekingHealth cardboard packaging and pulled out a bottle of SeekingHealth Lactase Drops that had leaked all over the inside of the box. At first I thought the top had just not been screwed on tightly enough, but then it became clear that the tamper-evident seal was broken too. This means that after the top was screwed tightly onthe bottle, somebody broke the tamper seal by opening it, did who knows what, put the cap back on loosely, and then sealed it inside the cardboard packaging.This had to have happened at the production facility, since it was sealed in the manufacturer's cardbard packaging.When I look at a dropper full of the liquid, it is cloudy, instead of the usual clear liquid. Between the broken tamper seal and the cloudy liquid, I am not going to use this. I tried to request a replacement, but for some reason, even though the item was fulfilled by Amazon, it says it is not eligible for return or replacement.[ Update: Amazon customer service did the right thing and refunded my money. Thank you Amazon! And I found another brand that is actually cheaper. Keeping this review at 1-star as it is inexcusable that the manufacturer marked this item as no returns or refunds. Seeking Health LLC should be investigating the problem and issuing a recall and refund on the entire lot: 193329 EXP01/22 ]

(Edit: I never buy from third party sellers - only from Seeking Health themselves so I know what I'm getting has been handled properly.) I have been using this product for at least a decade. Sometimes I can't find Seeking Health brand in stock anywhere and have tried other brands. That happened this week and the other brand was a train wreck. With Seeking Health, I use 10 drops per quart of goat milk (4 US cups. Approx 1 liter.) as my maximum dose for 24 hours. You might need more or less, we all process lactose differently, and cow milk has slightly more lactose per cup than goat milk (like 12 grams in cow milk vs 9-10 in goat milk). And our tolerance can change over time, and even from day to day, depending upon what else we're eating with the lactose-rich food, and whether we take any probiotics that help degrade lactose in our guts, whether we're stressed, whether we take meds that change our tolerance etc.Seeking Health brand NEVER contributes to making me sick - ever. I trust these people at their company.When I tried Lacteeze/Gelda, MilkAid from Ireland, a Dutch brand that I forget the name of, and some other brands, they either outright failed, or caused me reactions, or caused the milk to swell up in the carton in the fridge, or caused the milk to smell off.I've decided if I ever can not get Seeking Health again, I will simply not have fluid milk to drink until I can get it again. It's worth waiting for stuff that actually helps me - stuff that I can trust - and that is Seeking Health.Fortunately, I also make yogurt, and if you allow the yogurt to go through a 24 hour ferment in a yogurt maker (have to keep it warm), the cultures will eat all the lactose in the milk, leaving you with lactose free yogurt (starting from non-lactose free milk).Hope this helps someone.Thank you, Seeking Health, may you be in business for (at least) 100 years! :-)

I bought this "Liquid Lactase" as part of a science experiment to show how lactase breaks down milk sugar into glucose and galactose. I added the product to milk and waited more than 24 hours and then I tested the milk with a glucose test strip and a glucose blood meter. I found no evidence of glucose in the milk which suggests the "Liquid Lactase" did not break down the milk sugar (lactose) the way it is supposed to do.I tested a different brand of lactase enzyme from Natures Way and it broke down the milk sugar into glucose very quickly so I know my test works. From my tests, it appears that there is no viable lactase enzyme in this "Liquid Lactase." My bottle was from Lot #8901510. You can do the test yourself on lactase products to see if they really contain lactase. All you need is some Diastix Reagent Strips for Glucose. You can buy them at most drug stores. Test the milk before you add the lactase enzyme and then test it again after you add the lactase enzyme. The longer you wait, the more glucose you will find. It also works more quickly if the milk is warm. Although don't heat up the milk past 130 degrees or you will risk destoying the enzyme.I contacted the President of Seeking Health, Ben Lynch, and informed him of my test results. He said he was going to look into it.P.S.(Jan 2012) I did this experiment again, 12 months later, with a new batch of the SeekingHealth liquid lactase drops and the new batch was effective in breaking down the lactose. In order to make sure that any lactase drops you are using actually have lactase enzyme, it might be wise to test milk with inexpensive glucose strips before and after adding the enzyme to see if it is really working. High temperatures during shipping can denature the enzyme.
