I usually prefer caffeine mints, and sometimes caffeine gum, both when I either don’t have time for coffee, or it’s too hot for non iced coffee. Also knowing that long times in traffic and knowing stopping for more coffee are always concerns. My favorite caffeine supplement is from another company and I don’t blame them specifically for the prices going up, as everything is up, and I’m sure there costs to manufacture are much higher lately. As much as I love that other product, I am not paying almost as much for a caffeine tablet as a cup of real coffee! Obviously making coffee, or espresso, at home beats stopping at the local coffee shop. Beats it financially, maybe not taste and options, but if I am going to blow $5 plus for a coffee (sadly what it costs here) I better enjoy it! Hot, or iced, non fat or low fat milk, and sugar free flavor. Anyway, when time is not going to allow frivolous coffee shop stops, these are probably the best value for caffeine supplements. The value is extremely competitive, the caffeine amount is perfect, as the 100 mg. size is very close (actually a tiny bit stronger) than a strong cup of coffee, usually estimated at about 80 mgs. These work fast and are easy to take a few extra on the road. Considering that there is not many things worse (maybe needing a bathroom stop qualifies) than being stuck in traffic late in the afternoon with no coffee shops around, or easily accessible, and these are absolutely perfect. Just remember, unlike mints, or gum, you do need a liquid to swallow them. But if you are frequently stuck in late day traffic, I assume that you already know this. Enjoy!

Good value and love that they are capsules rather than tablers for quicker action.

I picked these up to manage energy levels during long workdays, but the experience has been inconsistent. Even when taking the same amount at similar times, the effects vary more than expected—some days feel overly strong, while others seem barely noticeable. From a formulation standpoint, that variability makes it difficult to rely on for predictable performance. The capsules themselves are easy to swallow, but I did notice a slight aftertaste on occasion. Over time, I also experienced a sharper drop-off in energy rather than a steady taper, which isn’t ideal for maintaining focus. While the quantity is generous, the lack of consistency in how it performs makes it hard to depend on as a controlled caffeine source.

I've used these for years. Their quality has been consistent, and each bottle seems to last me quite a while. I originally had been using the 200 mg doses, but lowered to the 100 mg over the past year so it doesn't add too much extra caffeine when I have too many sodas, etc. It's never upset my stomach, and I've experienced no side effects. The product increases my energy level but not to the point of being jittery. I take them when I have woken up early and need a bit of extra energy for the morning, or when I'm feeling a bit sluggish and need to focus on work tasks.

So glad we modern product ordering these days. This is a great product that helps with the morning workday start up. I was getting close to needing more, so to the Pharmacy I go. After seeing a limited option for Caffeine, I realized which online subscription I need to start

I tried two Nutricost 100mg caffeine pills today to compare it to the feeling I get when I take two Kaged 100mg caffeine pills (B0C7RCV9K3). Normally I only take one pill a day but I wanted to be able to tell the difference between the two. Oh my God… Kaged is way smoother! It’s such a beautiful, gentle pickup. On the other hand, Nutricost felt like I had a pack of wild horses in my chest for hours! 😂 Even though Kaged is 5x more expensive (Kaged is 15 cents a pill, Nutricost is 3 cents a pill), 15 cents for “a cup of coffee” is still a great deal. I asked Grok why there was such a big difference in the experience of it and it said because Kaged is a natural extract and it’s released more slowly whereas Nutricost is synthetic and it hits you all at once. Grok: The jittery feeling from Nutricost's caffeine pills (which use synthetic caffeine anhydrous) versus the smoother experience from Kaged's PurCaf (organic caffeine from green coffee beans) largely comes down to differences in how they're sourced, processed, and absorbed by the body. While both deliver the same core molecule—caffeine—their effects can vary due to absorption rates, purity, and the presence (or absence) of natural plant compounds. Here's a breakdown based on available insights: 1. **Absorption Speed and Energy Delivery** - Synthetic caffeine anhydrous, like in Nutricost, is a highly concentrated, lab-produced form that's designed for rapid absorption through the digestive system. This leads to a quick spike in blood caffeine levels, which can feel like an intense, immediate energy rush—but it often results in side effects like jitters, nervousness, or an elevated heart rate, especially if you're sensitive to caffeine or take it on an empty stomach. - In contrast, PurCaf organic caffeine is extracted from green coffee beans using a water-based process, which allows for a more gradual absorption. This creates a steadier, sustained release of energy without the abrupt peaks, making it feel smoother and less likely to cause those shaky sensations. 2. **Accompanying Compounds and Buffering Effects** - Natural sources like PurCaf retain beneficial plant compounds, such as chlorogenic acids (antioxidants found in green coffee beans), vitamins, and other methylxanthines. These act as natural "buffers," slowing down caffeine's release and modulating its impact on the nervous system. This can promote better mental clarity, focus, and a more balanced energy profile, reducing the risk of jitters or post-boost crashes. - Synthetic anhydrous caffeine is stripped of these extras during manufacturing (often derived from chemicals like urea), so it's essentially pure caffeine hitting your system all at once. Without those modulating elements, it's more prone to causing overstimulation or uneven effects. 3. **Production and Purity Factors** - PurCaf's organic, chemical-free extraction from non-GMO green coffee beans avoids potential impurities or residues from pesticides, which some users report contributes to a "cleaner" feel overall. This aligns with reports that organic caffeine is gentler, particularly for people prone to anxiety or side effects from synthetic versions. - Synthetic forms can sometimes include trace manufacturing byproducts, though high-quality ones like Nutricost's are generally pure. Still, the lack of natural synergy often leads to a harsher experience for some. Individual factors like your tolerance, dosage, hydration, and whether you eat with it also play a role—e.g., starting with half a dose can help mitigate jitters from either. If this persists or concerns you, consulting a doctor is a good idea, as caffeine sensitivity varies widely. Overall, if smoothness is key, sticking with natural options like PurCaf tends to be better for avoiding that wired feeling.
