The F3 family.

What's the difference between F3 Pure, F3 Mood, and F3 Energy?

Three brands, three different moments. F3 Pure is a clean-sweetened energy drink for everyday life: 120 mg of caffeine from green tea, sweetened with organic cane sugar, monk fruit, and stevia, with no artificial sweeteners. F3 Mood is calm and focus in a can: caffeine-free, built on chamomile, GABA, magnesium, and valerian root, and it is not a sleep aid. F3 Energy is premium functional energy: 120 mg of caffeine plus a nootropic stack (panax ginseng, L-theanine, BCAAs, ginkgo biloba), zero sugar, and NSF Certified for Sport. Same standard across all three.

Can I mix brands in one order?

Yes. One cart, one checkout, across all three brands.

F3 Pure.

What is F3 Pure?

F3 Pure is a clean-sweetened functional energy drink: 120 mg of caffeine from green tea and a functional stack (L-theanine, BCAAs, ginkgo biloba), with 20 calories and 5 g of organic cane sugar per can. It is sweetened only with cane sugar, monk fruit, and stevia (Reb M), with no artificial sweeteners and no preservatives.

Does F3 Pure have artificial sweeteners?

No. F3 Pure uses organic cane sugar, monk fruit, and stevia. There is no sucralose, no acesulfame potassium, and no aspartame. That is the main difference between Pure and most zero-sugar energy drinks, which rely on artificial sweeteners to hit 0 calories: Pure trades 20 calories and 5 g of real cane sugar for a clean sweetener profile.

How much caffeine is in F3 Pure?

120 mg per 12 oz can, from green tea. That is comparable to a strong cup of coffee, and it is paired with L-theanine, an amino acid found in tea. For reference, the FDA cites 400 mg per day as a level not generally associated with negative effects for healthy adults.

Is F3 Pure good for an active lifestyle?

That is exactly who Pure is made for: a morning walk, a Pilates class, a workday that does not quit. It is a clean-sweetened, 20-calorie functional energy drink with a short ingredient list, designed for everyday active routines rather than heavy training.

F3 Mood.

What is F3 Mood?

F3 Mood is a caffeine-free calm-and-focus drink built on chamomile, GABA, magnesium, valerian root, and L-theanine, with zero sugar and zero calories. It is designed for high-stakes moments (the shift, the deadline, the back-to-back) when you need to stay clear-headed.

Is F3 Mood a sleep aid? Will it make me drowsy?

No. F3 Mood is not a sleep aid and is not designed to make you drowsy. It is built for calm plus focus: chamomile, valerian, and magnesium take the edge off while L-theanine supports clear attention. Think composure, not sedation.

Does F3 Mood have caffeine?

No. F3 Mood is caffeine-free by design, with zero sugar and zero calories. Its ingredients are chamomile extract, GABA, magnesium gluconate, valerian root extract, and L-theanine.

When should I drink F3 Mood?

Whenever the noise is loudest: before a stressful meeting, mid-shift, after training, or in the evening wind-down. Because it is caffeine-free, it will not keep you up, but it is not formulated to put you to sleep either.

F3 Energy.

What is F3 Energy?

F3 Energy is a premium functional energy drink: 120 mg of natural caffeine from green tea plus a nootropic-leaning stack of panax ginseng, L-theanine, BCAAs (2:1:1), and ginkgo biloba, with zero sugar and zero calories. It is built for training, competition, and work that demands focus, and it is backed by a roster of MMA and combat-sports athletes.

Is F3 Energy NSF Certified for Sport?

Yes. F3 Energy is NSF Certified for Sport, the independent certification athletes and leagues rely on to verify that what is on the label is in the can and that the product is screened for substances banned in sport.

Does F3 Energy contain nootropics?

Yes. F3 Energy's stack is nootropic-leaning by design: panax ginseng (43 mg), L-theanine (50 mg), ginkgo biloba (40 mg), and BCAAs (362 mg, 2:1:1), paired with 120 mg of green-tea caffeine. On The Joe Rogan Experience (JRE MMA Show #159), Quinton "Rampage" Jackson put it simply: "It's got ginseng... good for the brain."

Which athletes drink F3 Energy?

F3 Energy is endorsed on camera by a roster of combat-sports athletes including Quinton "Rampage" Jackson, Henry Cejudo, Frank Mir, Tito Ortiz, and Benson Henderson, many of them on The HJR Podcast. The brand was also featured on The Joe Rogan Experience when Rampage brought it on air (JRE MMA Show #159).
