Nutri Sperse Mct 70
Also known as: MCT oil, medium-chain fatty acids, Nutri Sperse MCT 70, caprylic acid, capric acid, Medium-Chain Triglycerides
Overview
Medium-Chain Triglycerides (MCTs) are a type of dietary fat composed of fatty acids with 6 to 12 carbon atoms, primarily caprylic acid (C8) and capric acid (C10). They are naturally found in coconut oil, palm kernel oil, and dairy fats. Nutri Sperse MCT 70 is a branded formulation, likely a concentrated MCT oil product containing approximately 70% medium-chain triglycerides. MCTs are rapidly absorbed and metabolized, providing a quick energy source and influencing metabolism differently than long-chain triglycerides (LCTs). They are commonly used for weight management, cognitive support, exercise performance enhancement, and nutritional therapy in clinical settings. Research on MCTs is extensive, with numerous randomized controlled trials, systematic reviews, and meta-analyses supporting their various applications.
Benefits
MCTs offer several evidence-based benefits. For weight management, a meta-analysis of randomized controlled trials (RCTs) indicates that MCT supplementation leads to a small but statistically significant reduction in body weight (~0.5 kg) compared to LCTs, with greater effects observed in interventions lasting 12 weeks or more and at doses below 8% of total energy intake. In terms of cognitive function, systematic reviews suggest that MCTs can improve cognitive scores in elderly individuals and patients with mild cognitive impairment or Alzheimer's disease, particularly in APOE ε4-negative individuals, with reported increases in MMSE scores by approximately 3 points over three months. Another meta-analysis shows that MCTs modestly reduce acute energy intake, suggesting enhanced satiety compared to LCTs. While evidence for ergogenic effects on exercise performance is less conclusive, some studies point to potential improvements in fat oxidation. These benefits are particularly relevant for elderly individuals experiencing cognitive decline, overweight or obese adults seeking weight loss, and athletes.
How it works
MCTs are unique in their metabolic pathway. Unlike long-chain triglycerides, they are absorbed directly into the portal vein and rapidly transported to the liver. In the liver, MCTs are quickly metabolized into ketone bodies, which serve as an efficient alternative energy source, especially for the brain. This process bypasses the lymphatic system and carnitine transport system required for LCTs. MCTs influence energy metabolism by increasing thermogenesis and may modulate satiety hormones, contributing to reduced food intake. In the brain, the ketones produced from MCTs can improve neuronal energy metabolism, potentially enhancing cognitive function. Their high bioavailability and rapid absorption are due to their shorter chain length, requiring less reliance on bile salts and pancreatic enzymes.
Side effects
MCTs are generally considered safe when consumed within recommended dosages. The most common side effects, occurring in over 5% of users, are gastrointestinal discomforts such as diarrhea, nausea, and cramping, particularly at higher doses. These symptoms are typically mild and transient. Uncommon side effects, reported in 1-5% of individuals, include mild headaches or temporary fatigue. Rare side effects, occurring in less than 1% of users, such as allergic reactions, are infrequent. There are no major reported drug interactions, but caution is advised for individuals taking medications that affect lipid metabolism. MCTs are contraindicated for individuals with fat malabsorption disorders, who should use them only under medical supervision. Studies in elderly and cognitively impaired populations have not reported significant safety concerns, indicating a good safety profile for these groups.
Dosage
The minimum effective dose for cognitive benefits has been observed around 6 grams per day. For weight loss, effects are seen with doses less than 8% of total energy intake. Optimal dosage ranges typically fall between 6 and 20 grams per day in clinical trials. Doses exceeding 16% of total energy intake may diminish weight loss benefits. The maximum generally tolerated safe dose is up to 30 grams per day; however, exceeding this amount significantly increases the risk of gastrointestinal side effects. MCTs are often administered with meals, with some cognitive studies suggesting administration with dinner. Nutri Sperse MCT 70 is likely an oil or powder formulation. MCTs are well-absorbed without the need for bile salts, and co-ingestion with other fats may influence their absorption kinetics. No specific cofactors are required, though some cognitive trials have explored co-supplementation with vitamin D and leucine.
FAQs
Is Nutri Sperse MCT 70 effective for weight loss?
Yes, it can lead to a modest reduction in body weight over several weeks to months, especially with consistent use and appropriate dosing.
Is it safe for elderly or cognitively impaired individuals?
Yes, research supports its safety and potential cognitive benefits in these populations, with no major safety concerns reported in studies.
When should Nutri Sperse MCT 70 be taken?
It is typically recommended to take MCTs with meals. For cognitive benefits, some studies suggest taking it with dinner.
How soon can I expect to see results from taking MCTs?
Cognitive improvements may become noticeable after approximately 3 months, while weight loss effects typically appear after 12 weeks of consistent supplementation.
Does Nutri Sperse MCT 70 cause side effects?
The most common side effects are mild gastrointestinal symptoms like diarrhea or nausea, which are usually dose-dependent and can be minimized by starting with lower doses.

- https://pubmed.ncbi.nlm.nih.gov/25636220/ – This systematic review and meta-analysis of RCTs found that MCT supplementation leads to a small but significant reduction in body weight (~0.5 kg) compared to LCTs, with greater effects observed in interventions lasting 12 weeks or more and at doses below 8% of total energy intake. The study highlights the potential of MCTs for weight management, noting moderate heterogeneity and some commercial bias in included studies.
- https://www.frontiersin.org/journals/nutrition/articles/10.3389/fnut.2022.802805/full – This RCT investigated the effects of MCT supplementation on cognitive function in elderly subjects, showing improvements in MMSE scores by approximately 3 points compared to control groups over a 3-month period. The study suggests promising cognitive benefits but notes limitations such as small sample sizes and a single-blind design, indicating a need for larger trials.

The review, while of good quality, primarily focused on short-term effects, indicating a need for more long-term studies on satiety and energy balance.
- https://journals.sagepub.com/doi/10.3233/JAD-230406 – This systematic review and meta-analysis of 10 studies concluded that MCTs improve cognitive function, particularly in APOE ε4-negative patients with mild cognitive impairment or Alzheimer's disease, showing a standardized mean difference of 1.87. The review acknowledged heterogeneity in interventions and populations but provided strong evidence for cognitive benefits in specific subgroups.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC9579472/ – This systematic review examined the effects of MCTs on exercise performance in athletes. It found some evidence for improved fat oxidation and certain exercise parameters, but the overall conclusion was inconclusive due to limitations such as small sample sizes and heterogeneity across studies. The review suggests that more robust research is needed to confirm ergogenic effects.
