Perpetuem Solids
Steady energy you can chew
Perpetuem Solids are chewable tablets made from the classic Perpetuem formula (non-2.0). They’re designed for long workouts and endurance events, especially when bottles, flasks, or mixing on the move isn’t practical.
Quick facts
- 3 tablets = 100 calories
- All flavours use the Classic formula
- Caffé Latte flavour includes 30 mg caffeine per serving
- Not meant to dissolve in water
- Perpetuem Solids are mainly an “add-on fuel” to help you hit your ideal hourly calories during training or racing longer than 2 hours.
They’re especially handy for:
- Ultramarathons, Long distance cycling and Iron distance triathlons
- Any time you want calories without carrying liquids
How to use (simple guide)
Serving: 3 tablets = 100 calories (33.3 Calories per tablet)
During exercise (2+ hours):
- Use them to top up your calories when you’re short
- If chewing all your calories sounds like a lot… you’re right.
A popular “sweet spot” combo (per hour):
-
2–3 tablets (≈ 60–90 calories)
+ -
1 serving/packet of Hammer Gel (90 calories)
= 150–180 calories/hour for many athletes
FAQs:
What is the difference between Perpetuem and Perpetuem Solids?
Perpetuem Solids use the same corn maltodextrin formula as Classic Perpetuem powder.
- A serving of 3 tablets provides 100 calories
- This is 10 more calories than 1 scoop of Perpetuem powder
You can use Perpetuem Solids as your main source of calories. However, most athletes use them as an additional fuel. They give you something to chew, without relying on sugary options like gummies or other solid foods that slow digestion and may cause stomach (GI) discomfort.
For most athletes, the ideal intake is 150–180 calories per hour. Perpetuem Solids offer a convenient way to help reach this target.
Why use Maltodextrin instead of sugar in your fuels?
Below are the key benefits of maltodextrin, including how it affects insulin during and after exercise.
1. Better digestion and calorie delivery
Maltodextrin allows you to digest more calories compared to simple sugars like glucose, sucrose, and fructose.
- It provides the full amount of energy your body needs
- It moves quickly through the digestive system without delay
Simple sugars must be mixed in very weak solutions to be digested properly. This means you won’t get enough calories.
If you try to increase the strength of a sugar-based drink:
- It won’t match your body’s fluid balance
- It will sit in the stomach undigested
- This can lead to severe stomach discomfort
Maltodextrin avoids these issues.
2. Fast and steady energy
Maltodextrin works quickly because it has a high Glycaemic Index (GI), the same as pure glucose (GI of 100).
- It delivers energy rapidly when you need it
- It provides more consistent and longer-lasting energy
Because it is made up of many linked molecules, it avoids the sharp highs and crashes (“peaks and valleys”) that are common with simple sugars.
What about insulin levels?
Maltodextrin does raise blood sugar quickly and triggers insulin release.
However, this is not a problem during exercise because:
- The body reduces insulin release during activity
- Hormones from the nervous system help manage energy use
- Muscles take in glucose efficiently with minimal insulin
In simple terms, insulin is not a limiting factor during exercise.
Is sodium phosphate safe to consume?
Yes. Sodium tribasic phosphate (sodium phosphate) is considered very safe, especially in the small amounts found in Race Day Boost and Perpetuem.
It has FDA “GRAS” status (Generally Recognised As Safe) and is used in food as:
- An emulsifier
- A nutrient
- A stabiliser
Toxicity levels (LD50) are extremely high. For example:
- A 75 kg person would need to consume around 555 grams to reach harmful levels
- This is far beyond any realistic intake
For comparison:
- Baking soda: 4,220 mg/kg
- Vinegar (acetic acid): 3,310 mg/kg
- Table salt: 3,000 mg/kg
This shows sodium phosphate is very safe in normal use.
Do Perpetuem Solids contain caffeine?
Only the Caffè Latte flavour contains caffeine.
It provides 30 mg of caffeine per 3-tablet serving
What’s the difference between Perpetuem powder and Perpetuem Solids?
Same classic formula. The difference is the format:
- Perpetuem Solids: chewable tablets
- 3 tablets = 100 calories
- Perpetuem powder: drink mix
- 1 scoop = 10 more calories than 3 tablets
Can Perpetuem Solids be your only fuel?
Technically yes, but it can mean a lot of chewing.
Example: larger athletes may need up to 6 tablets per hour—doing that for hours can cause jaw fatigue. Many athletes use Solids as a part-time calorie filler, not the whole menu.
INGREDIENT BREAKDOWN
Maltodextrin – A high-glycemic index (GI) complex carbohydrate, ideal for providing fast-acting, long-lasting energy during exercise.
Isolated Soy Protein – A dry powder food ingredient that has been separated or isolated from the other components of the soybean, making it 90 to 95 percent protein, and nearly carbohydrate- and fat-free.
MoistureLOK® (Grape Juice, Rice Dextrin) – This all-natural, low-sugar sweetener plays an important role in Hammer Gel’s delicious flavor while contributing minimally to the overall carbohydrate content. MoistureLOK® is certified non-GMO, gluten-free, and allergen-free.
Soy Lecithin – The extract from soybean oil, lecithin is an easily digestible source of healthful fat. This helps create a feeling of satiety and also supports the body’s natural fat-burning capabilities.
Sodium (Tribasic) Phosphate – This compound enhances the functioning of all three of the body’s ATP-producing energy systems—the short-term ATP-CP system, the medium-term lactic acid system, and the long-term oxygen/aerobic system.
A primary benefit of sodium (tribasic) phosphate is its ability to buffer blood acidity and help maintain a more ideal acid-alkaline balance by neutralizing excess hydrogen ions within the muscle cell. Effectively buffering lactic acid extends energy production within this system. This nutrient also increases 2,3 diphosphoglycerate (2,3-DPG). This compound, found in red blood cells helps release oxygen from hemoglobin into the muscle cells. An increase in 2,3-DPG will improve the availability of oxygen to working muscles during exercise.
L-Carnosine – This dipeptide (a combination of two amino acids) L-carnosine is a potent lactic acid buffer. It also offers antioxidant support.
L-Carnitine Tartrate – L-Carnitine Tartrate is a compound containing L-carnitine chelated (“bonded”) to L-tartrate, which is a salt of tartaric acid. L-carnitine is the key nutrient involved in the shuttling of fatty acids into the cell for energy production. Tartrate is a potent antioxidant.
Choline Bitartrate - A type of B-complex vitamin that helps with efficient use of body fat stores as energy. Choline bitartrate also supports enhanced cognition, learning, and memory.
Stevia – A natural, calorie-free sweeter derived from the leaves of Stevia rebaudiana, a plant native to Central and South America. It does not affect blood sugar levels or contribute to tooth decay like sugar does.
Chromium Polynicotinate – This trace mineral helps regulate blood sugar and plays a vital role in energy production.
