Effective dietary supplements for weight loss: market review

I. Introduction: growing demand and complex choice

The market of biologically active additives (dietary supplements) to reduce weight is experiencing rapid growth, fueled by the desire for an ideal figure and simplified solutions in the fight against excess weight. However, this market is characterized by a huge variety of products that vary in composition, efficiency and safety. Consumers often face difficulties when choosing an effective and safe tool, risking not only a useless, but also a harmful product. The purpose of this review is to provide a comprehensive analysis of the market for weight loss, covering key ingredients, action mechanisms, evidence, risks and recommendations for choice.

II. Classification of dietary supplements for weight loss: key categories and action mechanisms

Dietary supplies for weight loss can be classified according to various criteria, the most important of which is the mechanism of action. Consider the main categories:

  • A. Thermogens:

    • The mechanism of action: Thermogenesis increase, that is, heat production in the body, which leads to burning more calories. They stimulate metabolism, increase the level of energy and suppress appetite.
    • Key ingredients:
      • Caffeine: One of the most common thermogenics. It stimulates the central nervous system, increases the frequency of heart contractions and blood pressure, contributing to the breakdown of fats.
      • Green tea extract (EGCG): Contains Epagallokatechin Gallat (EGCG), a powerful antioxidant, which is believed to enhance thermogenesis and oxidation of fats.
      • Sinefrin: Gorky orange extract, structurally similar to ephedrine (prohibited substance). Stimulates beta-3 adrenergic receptors, contributing to the breakdown of fats and suppression of appetite.
      • Capsaicin: Contained in acute chili pepper. Increases thermogenesis, suppresses appetite and improves metabolism.
      • Yohimbine: Alpha-2 adrenergic receptors blocks, which can contribute to the breakdown of fats in problem areas (for example, hips and stomach). It should be used with caution due to potential side effects.
    • Evidence base: The effectiveness of thermogenics varies depending on the ingredient and dosage. Caffeine and green tea extract have a relatively good evidence base confirming their effect on metabolism and fat burning. Sinefrin and Yochimbin require further research.
    • Risks: An increase in blood pressure, rapid heartbeat, anxiety, insomnia, headaches, gastrointestinal disorders. People with cardiovascular diseases, hypertension and anxious disorders should avoid thermogenics.

  • B. carbohydrate blockers:

    • The mechanism of action: Inhibit the action of enzymes that split carbohydrates in the intestines (for example, alpha amylase). This leads to the fact that part of the carbohydrates is not digested or absorbed, which reduces the total number of calories consumed.
    • Key ingredients:
      • White beans extract (Phaseolus vulgaris): Contains pheasolamine, alpha-amylase inhibitor.
      • Hitosan: Received from chitin contained in the shells of crustaceans. It is believed that chitosan binds fats in the intestines, preventing their absorption. However, the evidence base for this statement is limited.
    • Evidence base: White bean extract has a moderate evidence base confirming its effectiveness in reducing weight and blood sugar after eating. The effectiveness of chitosan remains controversial.
    • Risks: Gastrointestinal disorders (bloating, gases, diarrhea), allergic reactions (especially to chitosan).

  • C. Fat blockers:

    • The mechanism of action: Prevent the absorption of fats in the intestines, connecting them and excreting them from the body.
    • Key ingredients:
      • Orlistat (Xenical): It is a drug, not dietary supplements, but its mechanism of action is similar to fat blockers. Inhibits lipase, an enzyme that breaks down fats in the intestines.
      • Hitosan: (mentioned earlier) is also positioned as a fat block, although its effectiveness in this capacity remains controversial.
    • Evidence base: Orlistat has a good evidence base confirming its efficiency in weight loss. However, its use is associated with a number of side effects. The effectiveness of chitosan as a fat blocker remains in question.
    • Risks: Fat diarrhea, fecal incontinence, deficiency of fat -soluble vitamins (a, d, e, k). Orlistat can interact with some drugs.

  • D. Suppliers of appetite:

    • The mechanism of action: Reduce the feeling of hunger and increase the feeling of saturation, which leads to a decrease in calories consumption.
    • Key ingredients:
      • Glucomanan: Soluble fiber obtained from the roots of the plant of connucky. It absorbs water in the stomach, forming a gel that increases the feeling of saturation.
      • 5-HTP (5-hydroxyryptophan): Precursor Serotonin, neurotransmitter, who plays a role in the regulation of appetite.
      • CLA (conjugated linoleic acid): Fatty acid, which is believed to reduce the fat mass and increases muscle mass.
      • Garcinia Extract of Cambodia: Contains hydroxilimonic acid (HCA), which is believed to inhibits the enzyme involved in the synthesis of fats and suppresses appetite.
    • Evidence base: Glucomannan has a moderate evidence base confirming its efficiency in weight loss. The effectiveness of 5-HTP and CLA requires further research. The evidence base for the Garzinia Extract of Cambodia is contradictory, and many studies do not confirm its effectiveness.
    • Risks: Glucomannan can cause bloating and constipation. 5-HTP can interact with antidepressants and cause nausea. Cla can cause gastrointestinal disorders. Garzinia Extract of Cambodia in rare cases was associated with liver damage.

  • E. Accelerators Metabolism:

    • The mechanism of action: They stimulate metabolism, increasing the speed with which the body burns calories.
    • Key ingredients:
      • L-Carnitin: An amino acid that plays a role in the transport of fatty acids in mitochondria, where they are burned for energy.
      • B vitamins B: It is necessary for the normal functioning of metabolic processes.
      • Chromium: A trace element that plays a role in regulating blood sugar and can improve insulin sensitivity.
    • Evidence base: L-carnitine can be effective in increasing physical endurance and restoration after training, but its effect on weight loss is limited. B vitamins are necessary for normal metabolism, but their additional technique will not necessarily lead to weight loss, if there is no shortage. Chrome can improve blood sugar level control, but its effect on weight loss remains controversial.
    • Risks: L-carnitine can cause gastrointestinal disorders. B vitamins in high doses can cause side effects. Chrome can interact with some drugs.

  • F. Probiotics and prebiotics:

    • The mechanism of action: The composition of the intestinal microbiots improve the composition, which can affect metabolism, appetite and inflammation.
    • Key ingredients:
      • Various probiotics strains (for example, Lactobacillus and Bifidobacterium): Living microorganisms that benefit the owner’s health when consumed in adequate quantities.
      • Inulin, Fructo -osaccharide (Jos): Prebiotics that serve as food for beneficial bacteria in the intestines.
    • Evidence base: Some studies show that certain probiotics strains can help reduce weight and improve metabolic indicators. Prebiotics can also have a positive effect on the weight and health of the intestine. However, additional studies are needed to determine the most effective strains and dosages.
    • Risks: Bloating of the abdomen, gases, constipation or diarrhea (especially at the beginning of the reception).
