Criteria for Product Evaluation

The niche of nutritional supplements has thousands and thousands of products. Some work while others have no effect at all. Some manufacturers and distributors concentrate on marketing and forget that quality comes first. Others do not give the right information and end up either misleading you or giving you false hope. We are convinced that our list of reviewed tablets has products that will meet your expectations. This is the criteria that we used to choose these products.

User reviews and ratings

user reviews

We went through user reviews and ratings from different online caffeine tablets sellers. We further sieved through and chose reviews from only verified customers. We also chose users who had reviewed the products without any bias and had not received any price discounts to influence their reports. We finally picked the caffeine tablets that had received the highest satisfaction ratings and positive detailed reviews.

Ingredients safety

We chose products with the safest ingredients and tried our best to list the active and inactive ingredients. We also chose different ingredients strengths, ranging from 100 to 200mg. Some of the products have undergone independent testing by third parties for ingredient, dosage and potency validation.

We also included products that are free of ingredients that may induce inflammatory reactions. Some of those ingredients include nuts, eggs, wheat, soy, dairy, and fish. We also considered tablets that are suitable for vegetarian diets.

Brand Reputation

We chose brands from manufacturers and distributors with a solid reputation for making products that are safe, effective and pure. For some of the brands that we have chosen, the manufacturers and facilities of production follow General Manufacturing Practices and are FDA approved. For other products, the manufacturers have been in business for long and in addition to caffeine tablets, they have been producing different very effective dietary supplements.

Possible side effects

We chose caffeine tablets that are likely to have fewer side effects. We prioritized tablets that are free of preservatives, artificial additives, and are free of potential allergens. These properties increase the likelihood of negative side effects and if possible should be avoided. For people with gluten and dairy sensitivity, we also included products free of these ingredients. We also considered non-GMO and vegetarian-friendly tablets.

Benefits of caffeine tablets

Caffeine was once demonized as being bad for healthy living. However, scientific studies have continually shown that caffeine, if taken in the right amounts can help you to prevent diseases and improve your physical fitness. Taking caffeine in a beverage is the most preferred way, but it comes with its drawbacks- it needs to be prepared and even worse, it requires sweeteners to make it more enjoyable. Caffeine tablets are convenient, cheaper, do not require any addition of sugar and can easily be carried around. The most important benefit is that with caffeine tablets, you can accurately quantify the amount of caffeine that you consume.

Stimulating the brain

Most people consume caffeine for the primary benefit of stimulating the brain, making it the most consumed psychoactive substance worldwide. Caffeine activates the central nervous system by promoting the release of several neurotransmitters, the most important being adrenaline. Scientific studies have found out that adrenaline stimulates the mind to be alert, boosts memory and improves blood supply to major body organs. As a result, caffeine helps in improving mental performance, alertness, attention, and concentration. For instance, a study reported by the European Food Safety Authority proved that 75mg of caffeine can significantly improve mental alertness and attention.

Improve wakefulness

Caffeine has largely been used a startup drink in the morning, in moments of tiredness or when working at night-time. A study conducted by staff from the Department of Psychology, University of Amsterdam, showed that caffeine is effective in improving performance, alertness, and concentration during sleep loss and even in many hours of sleep deprivation. The researchers went on to explain that caffeine can be effectively be used to help in controlling wakefulness rather than as a method to disturb sleep.

Enhance exercise performance

Caffeine is a performance aid that is approved, legal, and has been used by athletes for a long time now. Caffeine improves blood supply to the muscles and promotes glucose breakdown to supply the working organs. Caffeine also mobilizes breakdown of fats, in the initial minutes of exercise, sparing glycogen stores for later stages. This effect enables you to workout for longer before exhaustion occurs. This property has made caffeine to be one of the key ingredients in most sports’ products like energy drinks and gels.

Lowers the risk of diabetes

Studies have suggested that caffeine can lower the risk of type 2 diabetes. A research study in the US showed that consumption of coffee daily, drops the risk of diabetes by at least 40%. Another study showed that caffeine has antioxidant properties which prevent several other diseases, not just diabetes. These effects are thought to be due to polyphenols present in caffeine, which increase insulin sensitivity and promote conversion of glucose to glycogen. For you to realize these benefits, you should avoid sweeteners and unhealthy fats. Caffeine pills are particularly good, as they do not require an addition of sugar.

If you already have diabetes, over-consumption of caffeine may worsen the condition. It would be wise to consult your doctor first, and always make sure that your sugars are always controlled.

Lowers the risk of cancer

As an antioxidant, caffeine neutralizes free radicals, decreasing the risk of cancer and other diseases by up to 49%. According to the American Cancer Society, latest studies have shown that coffee reduces the risk of cancers of the prostate, liver, endometrium, mouth, and throat. These effects are most significant when caffeine is consumed together with plenty of fruits and vegetables.

Caffeine dosage: How much is safe?

It is difficult to pinpoint the amount of caffeine that everyone needs as people have different needs and tolerances. For some people, 50mg may take them for the whole day while others, 200mg may only las for few hours. for the upper limits, research is available on what quantity is too much.

Most research studies suggest that 300mg-400mg is relatively safe, and can be consumed daily with no adverse effects. A study reviewed by the European Safety Authority reported that 400mg for adults is harmless, and one-time doses of 200mg for athletic purposes are safe.

Ingestion of too much caffeine can be fatal, especially for people with a heart disease. Cases of caffeine-induced cardiac events have been reported in the past. It is therefore, wise to observe the recommended dosages. Of concern, are doses above 500mg within a short period of time. It can lead to accelerated heartbeats, muscle tremors, and migraines.

In case of overdose, you should immediately seek medical help. Signs and symptoms of overdose include agitation, anxiety, confusion, frequent urination, irregular or fast heartbeat, muscle twitching, ringing in the ears, seizures, stomach pain, and trouble sleeping.

Take home message for dosage of caffeine tablets is to adhere to the directions of use by the manufacturer. Remember not to take double doses, and if really needed, you should wait for at least four hours to elapse.

Precautions

Caffeine should be treated like a drug and should be taken with caution. You should take the recommended dosages and in some instances that we are going to discuss below, you should first seek official advice before taking caffeine tablets.

Allergy

If youexperienced had any previous allergic to caffeine or any caffeine-containing substances, you should not take caffeine tablets. The highest chances are that you may have a repeat allergic reaction.

Drugs

If you are currently on any drug (over-the-counter, prescription, herbs or supplements) you should first inform your doctor or pharmacist. Caffeine can interact with other drugs to either reduce their effectiveness or increase their potency. Therefore, caffeine can cause some serious side effects when combined with other drugs.

You should take special caution if you are consuming any central nervous system stimulants, cardiac drugs, oral contraceptives, or any psychiatry drugs.

Medical conditions

Caffeine may worsen certain disease conditions. It is a rule to consult your doctor before taking any drug, if you have any medical condition- caffeine is no exception. Caffeine may cause further deterioration of disease such as cardiac disease, hypertension, liver disease, renal dysfunction, seizures, and diabetes.

Children below 12 years

Caffeine is not recommended for children below 12 years as the brain is still developing. Caffeine crosses the Blood Brain Barrier and may lead to abnormalities in behavior and socialization. Furthermore, caffeine tablets have no nutritive or growth benefits to children yet kids at this age should be concentrating on meeting their growth spurts’ needs.

Pregnancy and breast feeding

For pregnancy, the US Food and Drug Administration has classified caffeine as a category C drug. This is because animal reproductive studies have shown that caffeine may cause embryotoxicity and teratogenicity to the fetus. Other studies have shown that moderate use of caffeine in pregnancy is acceptable as it does not cause a measurable risk. We strongly recommend that you should first talk to your obstetrician before taking caffeine tablets. If the benefits outweigh the risks as assessed by a specialist, they may give the approval to go ahead and take the tablets.

For breastfeeding mothers, caffeine is not recommended as it passes to breastmilk. Caffeine in infants causes jitteriness, fussiness and poor sleeping patterns. If you would like to take the tablets and you are breastfeeding, we recommend that you should first express milk before taking the tablets then wait for about three to four hours before the next feeding session.

Driving

High doses often cause dizziness especially in the first 30 minutes of use. Therefore, you should avoid driving or operating machinery, especially if you have taken a high dose.

Sleep

Caffeine can interfere with your sleep pattern. You should therefore, not use it as a replacement for sleep or shortly before bedtime.

Caffeine and alcohol

The Dietary Guidelines for Americans warns against consuming caffeine together with alcohol as when they are mixed, one may end up drinking more alcohol as caffeine masks the depressant effects of alcohol.

Potential side effects

sport gel side effectsJust like any other drug, caffeine has some potential side effects. However, it is not every person who may experience the side effects. Some of the effects are less serious and may not need any intervention while others warrant for immediate medical help. Also, note that some of the effects may be experienced within the first 30 minutes of consumption, then disappear.
