1 DB Overdrive Review: Worth the Money?

Here’s our 1st Phorm 1 Db Overdrive Review, as well as our coverage of 1 DB Overdrive Fastpack reviews. 1 DB Overdrive is a fat burner supplement claimed to naturally enhance your body’s ability to burn fat and control cravings. Are these claims accurate? How will 1 DB Overdrive work for you? Let’s start with the article at a glance.


  • B vitamins for energy
  • The caffeine+L-Theanine combo sustains focus and reduces jitters
  • Contains good carb blockers
  • Some ingredients work to reduce estrogen and cortisol


  • Lacks a better natural thermogenic and an appetite suppressant
  • Hidden ingredient doses prevent us from knowing if they’re effective
  • Contains the aggressive stimulant Synephrine

[1 DB OVERDRIVE REVIEW SUMMARY] 1DB Overdrive should give you results to some extent. You may notice powerful effects shortly after taking this supplement – especially in terms of energy levels and motivation. However, there’s a reason why 1 DB Overdrive is so strong: it contains a number of aggressive stimulants. These will make you jittery and potentially cause other side effects when combined, which means you’ll need to be careful with your caffeine intake throughout the day. What’s more, 1 DB Overdrive consists of 3 proprietary blends which prevent us from assessing if the ingredients are safely and effectively dosed for long-term use. Since it’s priced at $70 for only 20 servings, we don’t currently rate it as one of the very best fat burners today.

1-DB Overdrive Review – The Basics

1 DB Overdrive is a “next-generation” thermogenics supplement from the well-known company 1st Phorm. It’s a new iteration of their previous fat burner formula – now featuring nootropic ingredients for brain health as well.

It’s meant to be more effective at burning away unwanted fat, curbing those nagging food cravings, and making the dieting process easier for you mentally.

So, does it really work? Let’s jump straight into the meat of the matter – aka, the ingredients – to find out.


1 DB Overdrive Ingredients

1-DB Overdrive has significantly changed its formula over the years. It now looks like this:

  • Thiamin (vitamin B1) (1.2 mg)
  • Riboflavin (vitamin B2) (1.3 mg)
  • Vitamin B3 (25 mg)
  • Vitamin B6 (20 mg)
  • Vitamin B12 (125 mcg)
  • Bitter Orange Extract (334 mg)
  • Green Coffee Bean (250 mg)
  • Green Tea Extract (250 mg)
  • Acetyl L-Carnitine (250 mg)
  • Caffeine Anhydrous (150 mg)
  • Grains of Paradise (50 mg)
  • Methylliberine (50 mg)
  • Theacrine (25 mg)
  • BioPerine (black pepper extract) (5 mg)
  • Toothed Clubmoss (2 mg)

Here’s a closer look at each ingredient:

Vitamin B3

Also known as niacin, this ingredient works to enhance your cardiovascular function, along with improving cholesterol markers. However, it’s not an ideal addition to a fat burner. For the simple fact that it’s been shown to worsen insulin sensitivity when supplemented.

In case you didn’t know, insulin sensitivity is what governs your blood sugar levels after you eat a meal. The worse it is, the bigger the energy crashes you’ll have throughout the day. Not only that, but poor insulin sensitivity makes it easy to store body fat, and very difficult to get rid of it.

Vitamin B6

Now, this is better. Although it doesn’t worsen insulin sensitivity like vitamin B3, vitamin B6 can actually help with areas of cognitive functioning – such as mood and mental energy. It doesn’t boost fat directly, but it can help keep you more mentally ‘in the zone’ so to speak while you’re cutting.

Vitamin B12

Vitamin B12 is best known for boosting energy levels in people who’re deficient in it. This effect is mainly achieved by enhancing red blood cell production as well as increasing oxygen supply to your brain and bodily tissues.

It’s not a noticeable boost, unless you’re severely deficient in the vitamin. It also doesn’t help with fat loss, other than possibly increasing your energy levels in the gym so you can train harder and burn more calories.

Caffeine Anhydrous

The most well known stimulant in the world, caffeine enhances your brain’s and body’s capabilities for a few hours after ingestion. It helps you have more energy, it motivates you to stick to your diet, and it kicks up your metabolism into higher gear helping you to burn more calories. However, as many of us know, caffeine comes with a dark side. Taking too much of the drug is counterproductive; leading to potentially unsafe side effects. The problem is, we don’t know the caffeine dosage in 1 DB Overdrive.


This is a naturally occurring organic compound that’s similar to caffeine in structure and effects. Although the evidence is limited, the existing research looks very promising; showing that theacrine leads to less tolerance than caffeine (meaning you can take it longer without the diminishment in effects). However, it’s known to have a sedative effect at lower doses, and the dose in 1 DB Overdrive isn’t known.


Synephrine (also known as Bitter Orange)is a compound structurally similar to the banned substance Ephedra. Although it can significantly ramp up stress hormones, it’s no safer than Ephedra in terms of causing heart palpitations, high blood pressure and other side effects that might make you think twice about taking it.

Huperzine A

Huperzine A has the ability to boost your brain’s acetylcholine levels, which leads to better memory and recall. However, safety of its long-term supplementation is debatable, plus it has no fat loss benefits.

Green Coffee Bean

Contains a group of molecules known as “Chrologenic Acid,” which has been shown to modestly benefit heart health and weight loss. Not many studies have been done on humans with this ingredient. What we know so far is that green coffee extract (and its compounds) may reduce the absorption of carbs you eat from food.

Green Tea Extract

Green Tea Extract is a great ingredient that not only enhances your metabolism. It also boosts antioxidant activity in your body by protecting cells from harmful free radicals. In doing so, it can lead to better energy levels and overall health. It’s a shame we don’t know its dose in 1-DB Overdrive; you need the right amount of green tea extract for it to work.

Acetyl L-Carnitine

Carnitine is a molecule that may enhance your energy levels and contribute to fat loss slightly. It plays an important role in shuttling fatty acids from food into your cells to make energy. The acetyl l-carnitine version is said to have better effectiveness for brain energy specifically.

Grains of Paradise

Also known as Aframomum melegueta, grains of paradise is an aromatic spice from West Africa related to ginger. Its seeds are thought to have weight loss effects. To what extent, it is not known as high-quality human studies are few and far between.


This is an isolated molecule found in coffee beans, tea, and other sources. It might give you a boost in concentration, but the studies are inconclusive.

Anything Missing?

The formula is missing another appetite suppressant such as Glucomannan or cayenne pepper to help with food cravings. This can be a game-changer in terms of sticking to your diet and seeing your goals through.

1 DB Overdrive is also deprived of blood sugar regulators such as chromium, which is a trace mineral that can help prevent weight gain.

Dosage Instructions

Directions for 1 DB Overdrive is to take 1 capsule early in the day to start with. After you’ve assessed your tolerance, you can take another capsule in the early afternoon, 30-45 minutes before your meal with a full glass of water.

Once you’ve been taking this supplement for a while and feel comfortable on it, the manufacturers say you can increase the dose to a maximum of 2 capsules twice per day.

A single serving of 1 DB Overdrive has 150 mg of caffeine. Coupled with other stimulants in this product, taking 2 capsules, twice per day can cause negative reactions if you are sensitive to stimulants. You shouldn’t take 1DB Overdrive too close to bedtime as it can interfere with your sleep.

Side Effects

1 DB Overdrive does come with a risk of side effects.

The high-dose combination of caffeine, Synephrine and other stimulants in 1-Db Overdrive could lead to the following side effects:

  • Insomnia
  • Racing heart
  • Anxiety episodes
  • High blood pressure

Always, always make sure to speak with your doctor before using stimulants, especially if you have a history of medical conditions!

Price and Value for Money?

One bottle (80 caps) of 1-DB Overdrive costs $69.99 on the 1st Phorm official website. If you take the recommended 2 capsules twice per day, this means it will only last you 20 days.

What About 1 DB Overdrive Fastpack?

1 DB Overdrive Fastpack Review

Here’s a quick 1 DB Overdrive Fastpack review. 1 DB Overdrive Fastpack is a 3-product bundle consisting of 1-DB Overdrive fat burner, Thyrodrive Thyroid supplement, and Opti-Greens supplements. It’s meant to be taken together to enhance fat loss and general health – more than 1-DB Overdrive alone can do. The entire bundle costs about $154.99 on the official website.

Using 1 DB Overdrive Fastpack is marketed to help you:

  • Maximize Fat Loss
  • Control Appetite and Curb Cravings
  • Extreme Energy & Focus
  • Optimize Digestion

So, does it really work? And is it worth the money? It’s difficult to tel without trying it out for yourself. As we’ve repeated, 1-DB Overdrive might cause side effects due to stimulants.

Then there’s the Thyro-Drive, a type of thyroid/metabolism supplement. It contains a mix of well-researched and effective ingredients, and some unproven ones like raspberry ketones. It should somewhat support your mental focus, however, thanks to its ingredients like L-Tyrosine.

You should bear in mind that combining so many ingredients across these three supplements (especially the ingredients in 1-DB Overdrive which include stimulants) can increase the risk of side effects if you’re sensitive.

Conclusion to 1 DB Overdrive Review

1 DB Overdrive is a decent weight loss supplement.

It contains a few great ingredients in green tea, caffeine and green coffee bean, but the stimulant combination of bitter orange and caffeine isn’t to our liking.

Due to the fact that it’s highly-priced and only has 1-2 servings per day, it’s not something we would recommend for most people who want safe and sustainable fat loss.
