Biolean II Review - Does This Weight Loss System Work? Are dangerous ingredients and adverse effects deal breakers?

Editor's Review: 4.0 / 5.0

biolean-II-product-imageBiolean II company employees, have you ever taken your own product? We wrote one of our in-depth reviews, closely examining the ingredients, side effects, clinical research and customer-service quality. Furthermore, we read through hundreds of dieter comments and customer reviews from all over the web. At last, we summed up all of the information we found to give you the bottom line.

EDITOR'S TIP: Substitute Biolean II with a proven fat burner such as Leptigen for better results.

What You Need To Know

Biolean II is basically a weight management herbal supplement program for both women and men. This product is supposed to help burn off fat, suppress appetite and enhance metabolism. The important ingredient in Biolean II tablets is Advantra Z, which is also known as Citrus Aurantium or Bitter Orange. However, this supplement also contains the following; Caffeine, Schizandrae Berry, Gymnema Sylvestre Leaf, Rehmannia Root, Hawthorne Berry, Jujube Seed, Alisma Root, Panax Ginseng, L-Carnitine, P-Phenylalanine, Euconium Bark, L-Tyrosine, Rhubarb Root and Calcium. To use this product, you need to take two brown tablets and one white tablet in the AM and one brown tablet in the PM.

This product has been available since at least 2010 and it’s sold online for $85 (28 servings). Some natural ingredients are found in Biolean II and no prescription is needed, but read on…

Dangerous Ingredients – Concerning?

According to our Research Editor, “Biolean II contains Advantra Z as a key ingredient, which contains Synephrine. Synephrine mimics the effects of Ephedra, a banned weight loss ingredient. This substance can lead to rapid heartbeat, increased blood pressure, stroke and heart attack.

One customer commented, “This is a terrible product. The ingredients are harmful and can lead to heart issues.”

“I got headaches and was extremely jittery when using this product,” said another user.

Adverse Effects – Another Concern

It’s clear from the customer reviews that Biolean II can cause certain adverse effects. One user reported, “These did not work for me. They didn’t suppress my appetite at all. They made me dizzy and gave me headaches. I would not recommend them to anyone.”

Another customer stated, “The only thing that I have got from it is an upset stomach and dizziness.”

Our research has revealed if there is a particular aspect of a weight loss pill or diet program that is especially troublesome (a painful/difficult exercise routine, dangerous ingredients, adverse effects) the probability of long-term success is rather low. So, if Biolean II does in fact cause adverse effects in a high number of people, this could be a serious problem.

Any Real Science?

We were unable to find any solid clinical research or science to support Biolean II and its weight loss claims. Unfortunately for us at DietSpotlight, we need to see some published clinical studies that back up the diet product and its ingredients for weight loss.

The Bottom Line: Does Biolean II Work?

Now the moment you’ve been waiting for: our bottom line on Biolean II. Well, we like that Biolean II contains some natural ingredients and we did find some positive comments about it online. On the other hand, we have some reservations about this diet product because it’s not backed by any real science. Also, we’re concerned about the dangerous ingredients it contains and the adverse effects some customers complain about.

If you’d like to get rid of more pounds, then we suggest you go with a product that is backed by solid clinical research, does not contain any dangerous ingredients and is supported by plenty of positive customer reviews.

Among the best products we’ve seen in 2015 is one called Leptigen. Its formula is a blend of four powerful ingredients that have been proven in published clinical research to help increase fat loss and kick-start metabolism. We can’t find any discussion of harmful adverse effects and customer comments on the internet indicate people are seeing great results.

The makers of Leptigen are so sure about their product they’re offering a Special Trial Offer, which is a positive sign.

What You Should Know

BioLean II is a "weight loss system" marketed toward women and men. This tablet supplement is all-natural. The retail price is $85, and it can be purchased online without a prescription. As with most oral weight loss products, BioLean II should be taken daily and is supposed to produce noticeable results rather quickly.

Consumers can find user testimonials on Amazon.com; one major pitch to this diet product is that is supposed to help consumers lose unwanted pounds safely. After using BioLean II for a couple of weeks the user should notice leaner muscle mass and a curbed appetite. Once the user gains more lean muscle mass the body consumes more calories and help the body lose weight.

List of Ingredients

The major active ingredient found in this diet drug is Advantra-Z, which increases the user's metabolism and ideally leads to weight loss

Product Features

BioLean II is a tablet supplement suitable for individuals that desire to shed excess body fat.

    This actually worked really good but it gave me migraines, which I never had before. I would still take it if it weren’t for the migraines. I’ve taken alot of diet pills and this totally curved my diet almost to the point where I would force myself to eat. Makes u really thirsty! I would recommend to people.

    I need to lose weight about 40 pounds is there any thing I need to no about this product



    From what I can tell, there are no clinical studies on this product. Is all that caffeine OK for high BP? Are you willing to be a part of an experiment? There are healthier, clinically-proven options available.

    Can I take biolean while breasfeeding



    I was instructed by my OB/GYN to wait until after breastfeeding to begin. He was very adamant about that. I’d check with your Dr first.

    would Biolean II effect my blood pressure? I took the first dosage yesterday. I was woken up at 2AM by some burning acid like feeling and flavor on my throat! is that common with BioleanII?


    Dr. Lee

    I have many patients taking Biolean II and loving it. Many of them have type 2 diabetes and hypertension. Biolean II will not increase your blood pressure. In fact after patient loss the weight their blood pressure will go down and some can even stop their medication for their hypertension. None of my patients reported reflux issue with Biolean II. Most common complaint is loose stool.


    Surgical P.A

    Not true,..I took it for a few months,then none day I passed out in the OR. They rushed me to the endoscopy suite and after an endoscopy they found about 14 erosions in my stomach. Biolean contains aspirin,which is not list in there ingredients. Aspirin has a synergistic effect with caffeine and allows better absorption through the bloodstream. Be careful..could be dangerous.
