Keto Diet Supplements: What Ingredients Make Them Work?

The ketogenic diet is a high-fat, low-carbohydrate diet that was first introduced in 1920 to treat children with epilepsy. The diet deprives the body of glucose, the body's main energy source, and instead uses stored fat called ketones as an alternative energy source. This state is called ketosis.

The keto diet is restrictive, and those following it may need to take supplements to meet their daily nutrient intakes and prevent deficiencies. Common ingredients in keto supplements include medium-chain triglyceride (MCT) oil, omega-3 fatty acids, and vitamins such as B1, B6, B9, B12, A, D, C, and iron. These supplements help prevent nutritional deficiencies and balance electrolytes, which are essential for proper hydration and nervous system function.

Some studies suggest that ketone supplements may have potential benefits for people with neurodegenerative conditions and certain health conditions, but more research is needed. Additionally, keto supplements may not be suitable for those with high blood pressure, heart failure, kidney disease, or liver disease.

It is important to consult a healthcare provider before starting any supplements, as they are minimally regulated by the Food and Drug Administration (FDA).

The role of MCTs and exogenous ketones in keto supplements

Medium-chain triglycerides (MCTs) are a type of saturated fatty acid commonly found in palm kernel oil and coconut oil. MCT oil is a supplement that is popular among keto dieters as it can help them quickly up their fat intake, which increases ketone levels and helps them stay in ketosis. MCTs are metabolised differently from long-chain triglycerides (LCTs), the most common type of fat found in food. They are broken down by the liver and quickly enter the bloodstream, where they can be used as a fuel source for the brain and muscles.

MCT oil can be easily added to shakes and smoothies or taken by the spoonful. It is important to start with a small dose to see how your body reacts before increasing to the suggested dosage. MCT oil may cause side effects such as diarrhoea and nausea in some people.

Exogenous ketones are ketones supplied through an external source, while endogenous ketones are produced naturally by the body. Exogenous ketone supplements are used by people following a ketogenic diet to increase blood ketone levels and help them reach ketosis more quickly. They have also been linked to other benefits, such as boosting athletic performance, speeding up muscle recovery, and decreasing appetite. However, research on exogenous ketones is limited, and many experts argue that these supplements are unnecessary for keto dieters.

Ketone supplements are available in the form of ketone esters or ketone salts. Ketone esters are the most potent type of supplement and may cause longer ketosis periods. However, they tend to be very expensive and have an unpleasant taste. Ketone salts are made by adding artificial ketones to electrolytes such as calcium, magnesium, potassium, and sodium. They are available in drinks, pills, and powders.

While ketone supplements can increase ketone levels in the body and imitate the state of ketosis, it is important to note that they may not be effective for weight loss. In fact, some evidence suggests that they may hinder it. Ketone supplements can also cause side effects such as nausea, diarrhoea, and stomach discomfort.

The importance of vitamins and minerals in keto supplements

The ketogenic diet is a high-fat, moderate-protein, and low-carbohydrate weight-loss plan. While it can be effective for weight loss, it can also lead to nutrient deficiencies, especially in vitamins and minerals. This is because the keto diet cuts out several food groups, including starchy vegetables, grains, and most fruits. As a result, keto dieters may need to take supplements to meet their daily nutrient requirements and avoid adverse health effects.

Vitamins

Vitamins are essential for the body's proper functioning and overall health. Here are some vitamins that keto dieters may need to supplement:

• Vitamin A is important for proper vision, growth and development, and immune system support. It can be found in meat, liver, fish, poultry, and dairy.
• Vitamin B complex includes eight types of B vitamins that have various roles, such as converting food into energy, supporting healthy skin and eyes, and promoting red blood cell production. Whole foods like dark green vegetables are good sources of B vitamins.
• Vitamin C acts as an antioxidant and is necessary for collagen synthesis, which provides structure and strength to the body. It can be found in citrus fruits and vegetables like broccoli.
• Vitamin D, also known as the "sunshine vitamin," is essential for calcium absorption, bone health, immune system support, and nervous system function. However, vitamin D deficiency is common, as it is primarily obtained through sunlight exposure. Fatty fish like salmon and eggs are good dietary sources of vitamin D.
• Vitamin K is crucial for blood clotting and maintaining strong bones. It can be found in green leafy vegetables and animal products.

Minerals

Minerals are essential for the body's proper functioning, and some, known as electrolytes, are particularly important on the keto diet. Here are some key minerals to consider:

• Sodium, potassium, and magnesium are electrolytes that are easily depleted on the keto diet, leading to symptoms like fatigue, muscle cramps, headaches, and heart palpitations. Keto dieters should focus on increasing their intake of these minerals through diet or supplementation.
• Calcium is the most abundant mineral in the body and is necessary for bone health, muscle and blood vessel contraction, and nervous system support. Keto-friendly sources include sardines, salmon with bones, kale, and broccoli.
• Iron is essential for creating hemoglobin, which delivers oxygen throughout the body. Iron-rich foods include beef, oysters, leafy greens like kale and spinach, and plant sources like lentils and beans.
• Zinc is found in almost all body cells and is crucial for wound healing, immune function, and protein synthesis. Meat, seafood, and dairy products are good sources of zinc.
• Phosphorus is an essential component of DNA and RNA and aids in cell repair. It can be found in sunflower and pumpkin seeds.

In conclusion, while the keto diet can be effective for weight loss, it is important to prioritize vitamin and mineral intake to avoid potential health risks associated with nutrient deficiencies. Supplementation can be beneficial, especially for those at a higher risk of deficiencies or those who struggle to meet their nutrient goals through diet alone. However, it is always recommended to consult a healthcare professional before starting any new supplement regimen.

The benefits of keto supplements for specific health conditions

The ketogenic diet is a high-fat, low-carbohydrate diet that can lead to weight loss and other health benefits. However, due to its restrictive nature, it may cause deficiencies in some essential nutrients. This is where keto supplements come in—they help fill the nutritional gaps that may arise when following a keto diet.

Neurodegenerative Conditions

Some studies suggest that ketone supplements may be beneficial for people with neurodegenerative conditions such as Alzheimer's disease, multiple sclerosis, Parkinson's disease, and amyotrophic lateral sclerosis. Ketone supplements may provide an alternative energy source for the brain and help reduce inflammation, which is often a contributing factor in these conditions.

Athletic Performance

Keto supplements, particularly exogenous ketones, have been linked to enhanced athletic performance. They can serve as an alternative energy source for the body during intense exercise, reducing the production of lactic acid, which can cause muscle soreness and weakness. This can lead to improved performance, especially for elite and endurance athletes.

Psychiatric Disorders

There is some emerging research suggesting that ketone supplements may be useful in treating psychiatric disorders such as depression, schizophrenia, and bipolar disorder. The metabolism-altering effects of ketone supplements may help regulate neurotransmitter release and reduce inflammation in the brain, thereby alleviating some of the symptoms associated with these disorders.

Epilepsy

The ketogenic diet has been used for many years to help reduce the frequency and severity of seizures in people with epilepsy. Keto supplements, particularly exogenous ketones, may help maintain ketosis, which is believed to be one of the mechanisms behind the diet's effectiveness in seizure control.

Digestive Issues

The high-fat content of the keto diet can be challenging for some people's digestive systems, leading to gastrointestinal symptoms like nausea, diarrhea, and bloating. Digestive enzyme supplements that contain lipases (enzymes that break down fats) and proteases (enzymes that break down proteins) can help alleviate these digestive issues.

Nutritional Deficiencies

Keto supplements can help prevent or correct nutritional deficiencies that may occur due to the restrictive nature of the keto diet. For example, vitamin and mineral supplements can ensure adequate intake of vitamins D, B1, B6, B9, B12, A, C, and iron, as well as electrolytes like sodium, potassium, calcium, and magnesium.

While keto supplements can provide these potential benefits for specific health conditions, it is important to consult with a healthcare professional before starting any new supplement regimen, especially if you have an existing health condition or are taking medications.

The potential side effects of keto supplements

The ketogenic diet is a very low-carb, high-fat diet. While it may provide benefits, it can be difficult to follow consistently. Some suggest that ketone supplements can help raise ketone levels in the body, imitating the state of ketosis achieved through a ketogenic diet. However, there are potential side effects to these supplements that should be considered.

Firstly, ketone supplements may not be suitable for those with certain health conditions. For example, individuals with high blood pressure, heart failure, or kidney disease may be sensitive to the high sodium intake associated with ketone supplements. Additionally, those with liver disease may need to avoid ketone monoester supplements.

Secondly, ketone supplements can cause gastrointestinal side effects such as nausea, vomiting, diarrhoea, and constipation. These side effects can be unpleasant and may deter people from continuing to take the supplements.

Thirdly, there is a risk of electrolyte imbalances when taking ketone supplements, especially for those with medical conditions such as kidney disease that affect the body's ability to regulate electrolytes. Electrolyte imbalances can have serious consequences, including an irregular heart rhythm.

Furthermore, ketone supplements may affect blood sugar levels, potentially leading to hypoglycaemia. This can make a person feel weak and lethargic. Additionally, ketone supplements that contain sodium could be dangerous for people with high blood pressure.

Lastly, there is limited research on the long-term effects of regularly taking ketone supplements. More studies are needed to fully understand the potential side effects and risks associated with their use.

In conclusion, while ketone supplements may be beneficial for some people, it is important to consider the potential side effects and consult a healthcare provider before starting any new supplement regimen.

The best alternatives to keto supplements

The ketogenic diet is a high-fat, low-carbohydrate diet that can lead to weight loss. However, due to its restrictive nature, it may cause vitamin and mineral deficiencies. While keto supplements can help fill these gaps, they are not the only solution. Here are some of the best alternatives to keto supplements:

• Focus on a "food first" approach: Wendimere Reilly, a registered dietician nutritionist, suggests that with good planning, it is possible to get adequate nutrition from food alone, even when following a keto diet. For example, to increase your fibre intake, you can consume more avocado, flaxseed, or chia seeds. Similarly, to boost your magnesium levels, you can include more spinach, broccoli, and kale in your meals.
• Transition to whole food sources: Lindsay Malone, a registered dietitian, recommends starting with supplements to keep things simple and then gradually transitioning to whole food sources. This approach can be more manageable for those who find it challenging to get all their nutrients from food alone.
• Increase vegetable intake: While the keto diet may make it harder to consume enough plant foods, it is important to note that vegetables provide various vitamins, minerals, and plant compounds that are essential for optimal body function. Aim to include more dark, leafy greens, nuts, avocados, and seeds in your diet.
• Consult a healthcare professional: Before starting any supplements, it is important to consult a healthcare provider, especially if you have specific health concerns or restrictions. They can advise you on whether supplements are necessary and recommend appropriate alternatives if needed.
• Prioritize nutrient-rich keto-friendly foods: To ensure you are meeting your nutritional needs, focus on consuming nutrient-dense foods allowed on the keto diet. For example, fatty fish like salmon and sardines are excellent sources of omega-3 fatty acids and vitamin D. Additionally, eggs are a good source of vitamin D and iron.
• Consider a whole-food-based fibre supplement: If you struggle to meet your fibre goals on a keto diet, a whole-food-based fibre supplement may be a more realistic and simpler option than trying to consume all your fibre from food sources. However, be sure to speak to a healthcare provider about the best type and amount of fibre supplement for your needs.
