Nutri-Thin Review - 6 Things You Need to Know


In the weeks that lead up to this review, I figured out whether Nutri-Thin actually works. We decided an in-depth look was in order, so we looked into the ingredients, side effects, clinical research and customer service quality. We dug through hundreds of comments and experiences. Then, with that information, we condensed and refined to give you the bottom line.

What You Need to Know

To start off, Nutri-Thin is a dietary supplement containing a mix of B vitamins and caffeine. Users are supposed to take two pills per day. You’ll spend about $40 on a one-month supply. One benefit is you can consume it anywhere.

Nutri-Thin, which was launched back in 2011, falls under EPX Nutrition. The company utilizes a direct-sales approach, not unusual in the supplement field.  Nutri-Thin seems harmless enough and there don’t seem to be any synthetic ingredients present in the blend, but read on…

Price – “Awfully High?”

Our first concern with Nutri-Thin ingredients was the higher than necessary price. “Taking the recommended dosage of two pills per day comes with a substantial price tag,” said our Research Editor. “This formula is essentially a multivitamin and caffeine supplement. You can buy that at the local convenience store.”

We found a bottle of 100 caffeine pills on Amazon for less than $10. You can find the same in a multivitamin. Taken together you have a comparable formula that will cost about $20 for a month. That’s about half that of Nutri-Thin.

Weight-Loss Supplement – “Is it Really?”

A closer look at the label shows that the entire ingredients list, other than caffeine, is made up of B vitamins. As we’ve stated, that makes this one a hyped up multivitamin. Clinical studies have shown caffeine boosts metabolism and energy, but so does coffee.

“There’s no reason to believe this supplement will work better than clinically proven, weight-loss products,” our Research Editor offers. “If there was something in this other than caffeine and B vitamins it may be worth the price, but as it stands there’s no reason to give this one a go.”

We’ve researched tons of supplements and found, over time, that one small thing, like high price, can be enough to reduce your chances of long-term success. If Nutri-Thin offers nothing to the consumer, there’s no reason to spend the $40.

The Science – “Validated?”

While Nutri-Thin mentions repeatedly that it is backed by science, we don’t see how that can be the case. There are studies into caffeine that show benefit when taken in conjunction with an exercise program and healthy diet, but that’s true of all forms of the stimulant. Clinical research does not say this supplement is any stronger than the ones you’ll  find online and in stores.

What Users Are Saying

"”I have been taking this for about a month. My skin is brighter, I’m more relaxed. I just feel all around better!! I would definitely recommend this product!”"

"”This is great for energy and balancing hormones. I feel much more energetic and have noticed my mood increasing significantly as of late thanks to this product.”"

"”This product has minimal effect on me might work for someone else.”"

The Bottom Line – Does Nutri-Thin Work?

So, what did we take away from our in-depth look at this one? We are generally unimpressed by the ingredients and cost of Nutri-Thin. For something that labels itself as an effective weight-loss supplement, it boasts nothing new or exciting. Nutri-Thin even charges as if it were a scientifically proven capsule, which it only hopes to be. We feel hesitant to suggest a product like this when it is outrageously priced and generally worthless as anything other than a stimulant.

If you’re still looking for a fat burner, you need to look for something that has clinically proven ingredients and that gives you a good value for your money.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It blends four powerful ingredients, which have been shown to help accelerate fat loss and boost metabolism in published research. Side effects don’t seem to be an issue and the online reviews look fantastic so far.

There’s even a Special Trial Offer going on right now for Dietspotlight Burn, so it couldn’t hurt to give it a try because even the company has confidence in it.

What You Should Know

Nutri-Thin is a weight loss supplement that claims to be backed by science. There are plenty of supplements that make that claim, but science doesn’t have anything to do with effectiveness. Water is backed by science as a means of feeling fuller, but that doesn’t mean you can smack a Backed by Science label on a bottle of water and claim it is a weight loss supplement. Nutri-Thin contains a bunch of B vitamins and one active ingredient – nothing spectacular.

List of Ingredients


  • Vitamin B3
  • Vitamin B6
  • Vitamin B5
  • Vitamin B12
  • Vitamin B9
  • Caffeine

Product Features

In all honesty, the only thing Nutri-Thin has going for it in terms of weight loss is the fact that it contains caffeine. Otherwise this supplement could be marketed as a multivitamin, not a weight loss product at all. There is 100 mg of caffeine per serving and a long list of B vitamins. As far as B vitamin supplementation goes, there isn’t really that much of each vitamin in the Nutri-Thin formula, so your morning vitamin is likely more effective than Nutri-Thin.

B vitamins have a short half-life in the body. You will notice a change in urine color to a bright yellow color soon after taking B vitamins. This happens when the body is finished using up the extra supply. The body cannot store B vitamins so it sheds the extra in urine.

As for the caffeine content – there is a question about how much is in each serving. The label claims one to two capsules is a serving, but 100 mg is listed on the label. We are left wondering if one capsule contains 50 mg of caffeine or 100 mg of caffeine. If one capsule contains 100 mg of caffeine, two capsules would contain 200 mg of caffeine. The difference between 100 and 200 mg of caffeine is extraordinary in terms of effectiveness and side effects.


  • All of the ingredients and amounts are listed for Nutri-Thin.


  • There is a question about how much caffeine is supplied per serving.
  • Nutri-Thin contains a bunch of B vitamins found in your average multivitamin.


Nutri-Thin is not a weight loss supplement in the true definition of the word. B vitamins are part of your daily multivitamin and 100 mg of caffeine can be consumed in your morning coffee. Nutri-Thin does not provide other proven ingredients like green tea or chromium to help boost metabolism and control hunger.
