I have been using these vitamins for several years....won't be without them.

Here are my results from taking the BTT 2.0 Tablets (full dosage)
The Positives-
1. Really helps with my IBS issues. The pain and cramping I usually have are gone after I have taken these tablets for a few weeks.
Also makes me very regular-my waste output has increased dramatically-both #1 and #2. I have issues with water retention and this seems to be eliminating them.
2. Weight loss. It's due to a combination of the flushing out of excess water/waste and a dramatically curbed appetite-I no longer eat as much as I used to-I sometimes won't finish a meal because I'm satisfied after only a few bites. I don't end up grazing on junk food before bed now because I don't crave it as much. I've lost 10 lbs in a month and a half.
3. Improved libido/sexual response/lubrication
4. Improvement in depression / better emotional wellbeing
Now the negatives.
1. Really awful gas until your body gets used to the tablets. Luckily I work alone at night so I can get away with passing gas, LOL...but I have serious bloat-causing gas that even Gas-X won't cure. I suppose it's from the pre/probiotics...but it is uncomfortable and embarrassing.
2. You will be too regular! Fortunately, I haven't had diarrhea like some reviewers have, but I am constantly having to use the bathroom several times a day. This stuff will flush you out very well, but it is inconvenient to have to stop and find a toilet every hour, especially if you are running about. I wean myself off the pills if I am expecting to go on a long trip so I won't have to search for a bathroom all the time.
3. It made my period extremely heavy. I have a hormonal imbalance so I only get two periods a year if I don't take medication to bring them on. Usually, they are scant and very irregular-I had been taking Femaprin to bring on a cycle while taking these, and I had a sudden period that was so heavy I nearly passed out from excessive blood loss (I'm anemic). I had to miss work because I couldn't stand up without being dizzy.
4. Very expensive. I wish these tablets were available for $30 a bottle...the current price is a bit hard to swallow...no pun intended.
5. Metallic aftertaste. Not terrible, but I have a weird aftertaste in my throat after taking these, along with a bit of heartburn.

Overall I am pleased with the tablets-the side effects do tend to lessen a bit the longer you take them. and are manageable with a lower dosage.

***Update, August 2022**
Still taking my tablets, but I've reduced the dosage to 2 a day. The price now is almost $60 for a bottle, so I'm trying to stretch out my supply. The pills are still effective, although the weight loss effect is not as pronounced at a lower dosage. Not as many side effects either, but it's still working. I can tell the difference once I've been off them for a few days.

They are large so take a bit to swallow, so I take the powder form. I like the taste but my husband doesn't, so takes the pills. My memory suffers a lot when I miss a day and my body a little. Have been us them for years now and won't ch. I've had very very bad experiences with other vitamins and won't risk going through it again.

I feel like I have more energy already! Just started them.

Nothing.
