One two-tablet serving of ENERGIZE has more caffeine than a serving of most other energy products, but the proprietary time-released technology releases quickly and over time.∆ⱡ
Suggested in a clinical study to last up to eight hours. So although it’s fast-acting, there’s no rush at the start. Just pure, clean energy to keep you going hard all day long!
No jitters. And no sugar crash at the end.∆ⱡ
Energize is composed of a combination of important vitamins and minerals, as well as a proprietary blend, which consists of L-tyrosine (an amino acid), glucoranolactone (a simple sugar), natural caffeine, theobromine (from cocoa trees), rhodiola, panax ginseng, and octacosanol. These premium ingredients work in tandem to help support safe, long-lasting energy.∆

Ziegenfuss, T.N., Mendel R.W., and Hofheins, J.E. Acute Metabolic Responses to Energize™ Administration in Healthy Men and Women. Ohio Research Group. Wadsworth, Ohio 44281, USA.
One of the first steps in examining the safety and efficacy of dietary supplements designed to increase mental acuity, performance, and energy is to characterize the physiological responses to acute administration. Objective: The purpose of this placebo-controlled, double-blind clinical trial was to determine the effects of acute (single-dose) Energize™ supplementation in healthy men and women. Methods : After giving informed consent and being cleared for participation by passing a screening physical, ten healthy men [mean ± SD age, height, weight (36.8 ± 1.2 y, 179.2 ± 2.8 cm, 88.3 ± 16.6 kg)] and ten healthy women (35.2 ± 6.9 y, 169.6 ± 4.3 cm, 61.6 ± 3.9 kg)] completed two trials using a counterbalanced design. Measurements of resting metabolic rate (RMR) and substrate oxidation, assessed via indirect calorimetry (Parvo Medics TrueMax 2400), were made at baseline (pre-ingestion) and for 10 minutes at the end of each hour for two hours post-ingestion; systemic cardiovascular activity (resting heart rate and blood pressure) were measured at 0, 30, 60, 90, and 120 minutes post-ingestion; and Profile of Mood States (POMS) were measured pre and 120 minutes post-ingestion. Results: Two-way ANOVA revealed a significant interaction (p<0.00004) for RMR between conditions. Specifically, ingestion of Energize™ caused a statistically significant increase in RMR at 60 min (11%; from 3.92 ± 0.32 to 4.35 ± 0.22 ml/kg/min, P<0.0001) and 120 min (14%; from 3.92 ± 0.32 to 4.46 ± 0.33 ml/kg/min, P<0.0001) compared to the placebo trial. No changes in heart rate, blood pressure, or POMS were noted between trials. Conclusions: These preliminary findings indicate that a single dose (2 tablets) of Energize™ safely and effectively increases RMR for at least two hours post-ingestion. Future research should: 1) determine how long RMR remains elevated from acute Energize™ administration; and 2) assess the effects of chronic Energize™ supplementation on body weight, body composition, and exercise performance.
Data are expressed as mean ± 95% confidence intervals. *Significantly greater (P<0.0001) than baseline and corresponding placebo value.

I have tried about 4 different brands of Focus/Energy supplements through Amazon. Honestly I can’t say that I have noticed much of a difference with those other brands. Energize seems to be the only type of supplement that I actually feel a difference in my energy levels. I would recommend Energize over just about any other brand on Amazon.
not for me – need something a little stronger w/ out the headache. Actually they have taken so much good product off the market , it’s sad.
I just start to taken this but so far so good, I hope I have no regrets about it
Great pick me up for those who don’t drink coffee.
Kept me going all through my 12 hour shift.
Nothing to dislike, fast shipping. When I use this product I split pill in half and take in morning before the gym. I’m small thats why I take half. I find that it helps with that little extra push. I’m sensitive to caffeine and this is why I like this product because I do not get shaky or irritable.
‘Energize’ is my favorite non-caffeinated energy supplement since last Winter 2018. I found it at the local drugstore and continued ordering through Amazon. The natural caffeine ingredient is ‘coffee arabica’. I take two (2) tablets once a day and I am energized through out the day with very little downtime. It is for this reason that it has become my favorite supplement for the last two seasons. I occasionally stack it with the ‘Stacker 2’ supplement also purchased in Amazon.
They give me the energy to make it thru my third full time job of the day
Slight pickup. Not as strong as 5 Hour; but no jitters.
I like the mental alertness and the constant and consistent energy levels. I am a cancer patient and the two problems I have is fatigue and a mental fog that never seems to go away. I take one of these tablets every day and those two problems seem to be dramatically reduced. I mean it’s a very noticeable improvement for me in my everyday life. I really like how it works for me.
This gives me energy without jitters.
