Why Smarter Exists

Built on formulas, not fame.

Smarter Vitamins wasn't built with celebrity endorsements, influencer hype, or trendy marketing. We built it the harder way: make thoughtful formulas, show you what's inside, and let the product earn the repeat order.

Clear labels. No proprietary blends. Ingredients chosen for a reason - not because they look good in an ad. 800,000+ orders later, we're still doing it the same way.

Why Caffeine+

Coffee works. This is just simpler.

The caffeine you already use - in a cleaner, more consistent format that does not need brewing, mixing, sugar, or a coffee run.

No time to brew

No line, no kettle, no waiting for a pot to finish. Take one softgel with water and move on - caffeine that fits a morning already in motion.

Clean formula

Caffeine for the lift, L-theanine for the pairing. No sugar, no flavor crystals, no proprietary energy blend. Two active ingredients, both shown clearly on the label.

No coffee stains

Coffee can leave stains behind. A softgel goes down with water and never coats your teeth like a cup of coffee or tea.

Pocket-sized

Keep a bottle in your bag, drawer, car, or carry-on. No thermos, no spill, no outlet, no cafe search. Caffeine that travels with you.

Consistent

Coffee strength changes with the brew, scoop, roast, and barista. One softgel gives you 200 mg caffeine every time.

No coffee acidity

For people who do not always want coffee first thing, this skips the coffee acidity and gives you caffeine in a simple softgel format.

Exact dose

200 mg caffeine. 100 mg L-theanine. No guessing whether today's cup was strong or weak - the same measured amount printed on the label.

Smoother caffeine feel

L-theanine is the reason people pair it with caffeine. It is the green-tea amino acid included here to help make the caffeine experience feel smoother and more balanced.

Good to know

FAQs

Each softgel contains 200 mg of caffeine + 100 mg of L-theanine.

200 mg is a meaningful dose of caffeine. For perspective, the caffeine in brewed coffee can vary considerably depending on the coffee, serving size, and preparation method.

If you are sensitive to caffeine or do not regularly consume it, take that into account before use.

L-theanine is an amino acid also found naturally in tea leaves. It is not a stimulant.

Caffeine and L-theanine have been studied together in human research examining attention and cognitive performance. Smarter Caffeine+ combines 200 mg caffeine with 100 mg L-theanine in one clearly labeled softgel.

Individual responses vary, and research has used different doses and study conditions.

Take one softgel with at least 8 fl oz of water, following the Suggested Use on the label.

Because caffeine affects people differently, assess your individual tolerance and avoid taking another serving simply because you do not notice an effect immediately.

Be careful about combining multiple sources of caffeine.

One Caffeine+ softgel already contains 200 mg of caffeine, so coffee, tea, energy drinks, pre-workouts, certain supplements, and some medications can quickly increase your total daily caffeine intake.

Always count caffeine from all sources, not just this product.

No. L-theanine does not guarantee a jitter-free experience.

Caffeine can cause jitters, nervousness, increased heart rate, upset stomach, or other unwanted effects in some people - especially those who are caffeine-sensitive or consume a larger total amount.

If caffeine consistently makes you uncomfortable, this may not be the right product for you.

It can.

Caffeine promotes alertness, and its effects can remain noticeable for hours. How strongly and how long it affects you depends on factors such as caffeine sensitivity, metabolism, regular caffeine use, and the time of day you take it.

If caffeine interferes with your sleep, take it earlier in the day and avoid using it close to bedtime.

One softgel already provides 200 mg of caffeine.

The FDA has cited 400 mg of caffeine per day as an amount not generally associated with negative effects for most healthy adults, but that is not a recommended daily target, and individual tolerance varies substantially.

Follow the product directions and remember that caffeine from coffee, tea, energy drinks, pre-workouts, food, supplements, and medications all counts toward your total intake.

Many adults consume caffeine daily, but regular use can lead to tolerance and physical dependence.

If you consume caffeine every day and later decide to reduce your intake, gradually cutting back may be more comfortable than stopping abruptly.

Use caffeine intentionally rather than automatically increasing the amount when you become accustomed to it.

MCT oil from coconuts is used as the oil carrier inside the softgel.

It gives Caffeine+ its convenient liquid-softgel format. We do not claim that the MCT oil makes caffeine stronger, makes it work faster, or turns it into a timed-release product.

Consult a healthcare professional before use if you are pregnant, trying to become pregnant, breastfeeding, taking medication, have a medical condition, or are particularly sensitive to caffeine.

Because each softgel contains 200 mg of caffeine, anyone who has been advised to limit caffeine should account for that full amount before use.

Discontinue use and seek medical advice if you experience concerning or persistent adverse effects.
