Questions & Answers

What is the purpose of the calcium in these?

You're both hilarious. To begin with, the tablet contains only a trace amount of calcium. It's not going to have any effect on you in any way. In a few ounces of spring water, there's probably more calcium dissolved than in one of these tablets. The person who guessed a binder came the closest to correctly answering the question. It is an indirect pH buffer, not a binder. Caffeine is an alkaline substance that is basic in nature. At pH 7 to 7, it is a weak base, meaning it is partially ionized. The pH of the body (7.5) is the same as that of pure water. 4), and so forth. Positive and negative charges must always be balanced in any solution. That means an acidic counterbalance to caffeine's basic (-) properties is required. ) charge. It's the phosphate that's originally bound to calcium as a solid that's causing the problem. When caffeine and calcium phosphate are mixed in a solution during the manufacturing process, the phosphate buffers the caffeine, so instead of the caffeine having all of the - When the phosphate is charged, some of the hydrogen from the phosphate is transferred to the caffeine, resulting in a balance between the two. caffeine that has been charged (ionized) and the caffeine that has been charged (ionized). Caffeine has a pKa of 8 and is therefore well-balanced. That is, at a pH of 8, 30 % of the caffeine intake is - Half of the charge is charged, while the other half is neutral, with an H ion neutralizing the -. charge. Because the pH of water and blood is less than 8, it's best to avoid it. If caffeine is present in the range of 7 to 30, the total will be 30. 0 to 7. To help balance the pH of the rest of the solution, it will want to hold on to more H from a donor such as phosphate. Caffeine is a pH buffer in the same way that phosphate is, though it isn't used in the same way that phosphate is. If the pH rises to around 8, on the other hand, After 30 minutes, caffeine will begin to release the majority of its H, acidifying the solution and bringing the pH level back into balance. Because pH and pKA are both measured on a logarithmic scale, caffeine will have an equal -. pH 8 results in a neutral charge. 30 it would have had 2010 - (negatively) charged molecules as well as as as as as as as as as as as Since the beginning, there has been an increase in - pH is set to 8. Phosphate provided the extra H ions, which brought the total to 30. Calcium has no bearing on this; it is only bound to phosphate until it is dissolved, after which it simply floats around in solution doing nothing. Because pH is determined by H, Ca2 or calcium ion has no effect on pH, which is why they combine phosphate with something like Calcium (or Magnesium, etc.) so that the phosphate does the buffering work after the Calcium or Magnesium has been separated from it in solution. You'll see examples of this in other preparations, such as eye drops, where a small amount of HCl or hydrochloric acid, or NaOH or sodium hydroxide, is used to balance out the pH, even though those are strong acids and bases and don't actually buffer like phosphate does; instead, they simply lower or raise the pH to an exact amount by pharmacist titration so the eye drops are in the right physiological pH range. Cl- or Na- Exactly like calcium, it has no effect. H+ or OH- performs the function of buffering Because it has three H binding sites and thus three different pKA's (equilibrium of neutral and -), the phosphate buffer is more complicated. charged) at three different pH levels

Are they coated or do they dissolve easily in water?

They're gone now. There is no coating on this.

Is this in the form of a pill or a capsule?

br>Instructions: Take one tablet up to three times per day. Between servings, allow 3–4 hours. Do not take more than three tablets per day.

What is the shelf life of the tablets (i.e. when do they expire)? Is it a year or a year and a half?

I used to shop at Wal-Mart a lot. 200 mg generic marts Tablets that contain caffeine I discovered some 5-inch ones in a travel bag. The age is six. They had the same effect as they did when they were first purchased.

Pure energy at its fullest possibility of Oh man, this sheet keeps you so jacked that you don't need the extra calories from coffee or to pay like 5-figures for it
5/5

When you can slam down a fistful of these with no calories and stay awake all day, you can focus on work, sports, or whatever you want to keep you going. If you need to keep up with your kids, it's also good for that, or focusing on that woodworking project you've been putting off for too long and your wife is getting on your case about, you're like FINE ILL FINISH THE BOOKCASE TODAY JUST LAY OFF ME Anyway, these are fantastic, and if I were you, I'd buy a tenth bottle.

So far, everything has gone well
5/5

I have a high caffeine tolerance, and I have ADHD, so I believe these would be more effective than the low-dose medication I'm on to help me focus. Just don't wait too long to use them! They'll keep you up all night, I've learned the hard way. Oh, and they make me feel like I have to urinate all the time, just like any caffeinated drink. Sorry for the tmi, but I just wanted to be straight with you!! If you're looking for a boost of energy and focus, these will do the trick!.

Do you enjoy waking up for a low price? I don't always want or have the time to drink coffee or tea
5/5

Sometimes I'm in a place where the coffee is bad, and I'm not the type to go to Starbucks and buy a cup - I don't drink coffee unless it's absolutely necessary, and I don't drink tea unless it's absolutely necessary. In addition, both take time to take effect. I don't always have that time, so I take a caffeine pill. br>br> You can have one anywhere because it's small, cheap, and portable. All of a sudden hits you - This is a good thing in my opinion. I used to take Jet Alert, but the 200mg strength didn't seem to work for me, though two of the 100mg seemed to work better. But why should money be thrown away? So I went on the internet and looked into it. Natrol High Caffeine is a stronger version of Jet Alert that feels cleaner. If I need more later in the day, I can bite one in half with my front teeth (the original pill splitter) (the other half goes in a separate case, because I'm not that gross). br>br>My preferred method is to set my alarm a little earlier than usual, wash one of these down, and then go back to sleep until I need to get up. I usually wake up before my second alarm, which makes the morning go much more smoothly. I'm not a morning person, but these things help me pretend to be one on occasion. Okay, I'm lying, but I can get up and do a lot more than I used to. I'm not going to stand in the shower for ten minutes staring at the wall. Alternatively, I've tried to cleanse my face with hand lotion rather than cleanser. Trying to make coffee out of ground hempseeds (insert vegan joke here) is another option. Hemp is a good source of protein, but a poor substitute for coffee.

It doesn't make me jittery in the least
5/5

These pills are extremely effective and do not cause me to feel jittery. br>Every day, I drank VERY powerful energy drinks. I was looking for a simpler and less expensive way to get my daily caffeine fix, so I chose one with 330mg of caffeine. I'm glad I decided to give these pills a shot. I take one in the morning and another half pill at lunchtime, and I believe it is a much healthier alternative to drinking energy drinks with tons of additives.

Legal, efficient, and cost effective! These are absolutely fantastic
5/5

I'm going to start with small doses so they're more effective, but seriously—this is better than a cup of coffee for me, and I'm a big coffee drinker. Caffeine overdose is a real possibility if you take more than three per day. It's not a good idea to have more than 500-word sentences. CAFFEINE MAXIMUM: 600 mg PER DAY! If you don't believe me, look it up. These little guys are less expensive and more legal than adderall, so take advantage of them!.

These actually do the job
5/5

Caffeine tolerance varies depending on the individual. What you put in your stomach, or rather, what you don't put in your stomach, matters as well; I recommend eating something light in the morning and waiting about ten minutes. 15 minutes prior to consumption I usually half anything over 200mg, especially if I'm also drinking coffee. If you don't feel anything, you probably ate too much the night before and are more likely to get a headache if you overdose. Before reading Amazon reviews, please conduct your own research on caffeine. The majority of products will work, but keep in mind that when the only ingredient is caffeine, you get what you pay for.

This stuff is effective
5/5

I figured I'd just get caffeine pills to help with my diet after learning that caffeine is the main active ingredient in most "diet pills. " Because I'm not a coffee or tea drinker, I decided to skip to the point. In the end, I lost 25 pounds. 6 months from now No, not solely as a result of these, but they did assist. I'm pretty sure I'll continue to take them to stay in shape. They work, and despite the fact that I am sensitive to caffeine, which usually makes me jittery, these don't.

What a fantastic pick-me-up! Because I'm bipolar and epileptic, my medications make me extremely tired all of the time
4/5

For me, B12 doesn't work well on its own, so I tried this. I deducted a star because it's hit or miss when it comes to enhancing my tremors to the point where I'm constantly shaking, can't hold anything, or walk down the stairs with jelly legs and stuttering. Other times, it works perfectly and I am able to complete my tasks. It doesn't make me jittery, but neither does any other form of caffeine. It takes a lot to get me up in the morning, so this is the ideal balance.
