Masszymes & probiotics for healthy gut flora
April 9, 2018

Size: 250 Verified Purchase

I'm so happy I discovered this product. I believe enzymes can help with all manner of problems and you cannot take too many. The recommended dosage is based on a healthy 150 pound male. Once your body uses the enzymes to break down and digest food, the body will put any excess to work in other places. I researched Enzymes when my dad was diagnosed with Stage IV Pancreatic Cancer. We started him on megadoses of BiOptimizers Masszymes, along with probiotics. He lived twice as long as doctors thought he would. Excruciation abdominal pain and trouble eating solid food is typical with Stage IV Pancreatic cancer. Dad ate up until a few days before he died, and he never experienced pain at all. Several other family members have had acid and bloating issues and were taking acid reducers. Since stomach acid declines as we age, there is no need for people to take acid reducers, in fact they do more harm then good. We stopped the acid reducers and started taking Masszymes & probiotics daily to help maintain healthy gut flora.

I happily have taken Masszymes for a few years, both with food and on an empty stomach before bed to get a cleansing detox overnight. Their overall higher dosage seems true after I compared amounts in several other popular enzyme formulas. For some months I took three bottles a month for accelerated cleansing, but now I am on the maintenance dose of one bottle a month. I plan to use Masszymes for years to come. The company's customer service is top-notch.

I have taken a lot of digestive enzymes over the years, with little result.... until these! Honestly, the whole BiOptimizers line is fantastic. I use the enzymes, the HCL, and the probiotic .... and they are the only ones I will buy from now on. I've wasted a lot of money on digestive products that do nothing, and buying lower priced products is just not worth it. I am a huge fan of these products and I will continue to use them.

Before you purchase this item go on YouTube and watch a short video on how this product works. It will blow your mind! I’ve been using this product everyday for about two weeks and I just ordered myself the big bottle. I’ve noticed improved gastrointestinal wellness, faster recovery and muscle growth. I’ve also noticed a lot of energy, mental clarity and focus. You definitely get what you pay for. These capsules are not cheap but you will notice a world of difference. I can honestly say these capsules have changed my life.

I've been using P3-OM for about 2 years now, it seems to work the best for me after sampling many other probiotics over time. I highly recommend their entire product line, as unique and diverse as it is. I'm glad it's finally on Amazon! Hopefully they will get the Gluten Guardian on here too!

I don't do a lot of reviews, however, after listening to these guys on the Ben Greenfield podcast I had to try this product. I am not on the ketogenic diet but wanted to see if I got an increase in energy. And it certainly delivered on that. All I use is one capsule in the morning and I like the energy I get from it. I have tried so many pretty workouts and they never left me feeling right. While this is not a pre-workout I like the boost. Great product.

Restored my faith in my diet...

Definitely works as advertised. I have been doing the Bulletproof diet for a couple months and hit a plateau after losing 38lbs. I was starting to get frustrated and carbs and sugar were looking very tempting. After taking Kapex for a few days I broke through a weight loss barrier I had been stuck against for a decade and regained my faith and reset my metabolism. I recommend this in combination with the BP diet and intermittent fasting. Throw in a protein fast once in a while and you may feel superhuman.

Reviewed after using one bottle with my wife. We have both used other digestive enzymes before so we have something to compare to. Overall, it's not that much different/better that some of the other "best" brands in that it and they are all very effective as supporting food absorption. The bonus is the metabolism boost you get. That is were it outshines other digestive enzymes. Because it also makes you a bit more alert, we don't take it after 2pm. Similar to caffeine, we found taking in at dinner challenge normal sleep timing. Though I use is for just that effect if I know I will need to have a late night. Strongly recommend giving it a try.

These actually work for better sleep !!! I had hiatal hernia surgery 3 years ago and have had trouble sleeping ever since. Tried countless products and have gotten the best results with this by far. It’s been 2 weeks and definitely tell the difference, wanted to give some time before leaving a review. Unfortunately I recently heard that Magnesium supplements can possibly lower blood pressure so going to look into that but for now I’m still taking them. :-)

So far I feel fine and truly grateful for the results.

Multiple forms of the most absorbable forms of magnesium in one formula. This is one of those products that makes a noticeable difference. I’ve experimented with up to 6 capsules per day with no negative side effects, unlike other cheaper forms of magnesium. Like other BiOptimizers products this one is well formulated.

First of all, I do not have Celiac Disease and don't recommend that anyone with Celiac try to find a workaround.

That being said, I am largely wheat free except for birthdays or special occasions where I just want to "eat socially". I ordered this for Thanksgiving which was also a birthday celebration for the family...pretty rough if you've been low/no wheat for awhile.

Well, Gluten Guardian makes a night a day difference for me. Sure, you still know you carbed up, but for me, I don't have that lingering shakey and headachy feeling afterward. For me, those feelings would linger for the next 24 hours. Gone with Gluten Guardian taken as late as with the first bite of food.

Birthday cake, Burger night, and Pizza night with the family have really turned into something I don't dread.

I don't use this as an excuse to eat garbage, but it is a lot easier to pick a place (for everyone else) to eat with this in my supplement arsenal.

I need to be 'clear' with this evaluation, because I am a long time (4 year) customer of the BiOp folks. To the point I take their 'masszymes and P3-OM probiotics' daily. These products have given me sustained relief from digestive 'challenges' I lived with for many years. I regularly consume a particular 'protein supplement' to aid in my workouts, and the downside is I can tend to constipate if I don't drink massive amounts of water. The products mentioned have given me a whole new life with regard to those issues. However, having just received the ConstiCleanse (essentially on a 'tip' from the BiOp Team) I did have the opportunity to 'give it a go' last night. I had consumed a sizable block of 'chipotle cheddar' cheese about 3 hours before bedtime. I felt 'heavy' already, and knew the potential consequences I would face later. Literally while brushing my teeth for bed I had a 'eureka moment' and went for my 'first' dose of the ConstiCleanse I had just received from Amazon. Okay, there's your 'build up' . . . and the 'follow up' is .. it's 10:30 AM, and the best way to phrase this I guess would be --> I had my obligatory coffee 2 hours ago followed by a definite 'cleanse' one hour later. This particular 'movement' was definitely apart from the usual experience I have with my customary BiOp regimen. No, I don't work for BiOptimizers though I know I sound like I 'drank the Kool Aid' .. so what do I tell you ? You'll just have to try the product .. or not .. but if you do, and have the reaction I just had - - then you'll know. . . . . Just Sayin'

I’ve been a long time BiOptomizers customer. I take their Masszymes and P3-OM probiotic daily. When they first released ConstiCleanse I knew with out a doubt that it would be just as top quality as their other products. I’ve been taking it for several months 3-6 days week depending on what life as going on for me. It safely and effectively relieves any digestion issues and makes me feel great all day after my morning ritual. You will not be disappointed. With this ridiculously low price right now you should stock up.

I feel better when I take two capsules with every meal. In addition, sometimes I take 3 capsules with 6 capsules of P3OM before bedtime. I like that it can be taken with meals as well as on an empty stomach. I believe it aids with digestion.
