đŋ Spirulina â a microalgae with a long history
Spirulina (Arthrospira platensis) is a microscopic freshwater microalgae that occurs naturally in alkaline lakes across Mexico and parts of Africa. The Aztecs harvested it from Lake Texcoco and processed it into dried cakes; today it is among the most thoroughly studied microalgae there are.
A recent dose-response meta-analysis from 2025 pooled 17 RCTs looking at body composition. In the combined analysis, spirulina supplementation was associated with statistically significant changes in body weight, BMI and body fat percentage, with longer supplementation periods producing more pronounced effects.
On blood lipids, a meta-analysis by Serban et al. (Clinical Nutrition, 2016) combined seven RCTs and observed reductions in total cholesterol, LDL cholesterol and triglycerides alongside a rise in HDL cholesterol. A more recent meta-analysis by Fu, Zhou and Gu (Frontiers in Nutrition, 2025), drawing on 23 studies and 1,035 participants, confirmed these lipid-related observations and added findings on blood pressure and body weight in overweight adults.
đĩ Matcha â concentrated green tea with high EGCG levels
Matcha is finely milled tencha green tea. Because the leaves are shaded before harvest and then consumed whole in powdered form, the intake of plant compounds is considerably higher than with brewed leaf tea. An analytical study in the Journal of Chromatography A (2003) found that the EGCG available from matcha can reach up to 137 times the level extracted from comparable brewed green tea.
A detailed critical review in Molecules (2022) brought together the existing human and animal literature on matcha â including work on cognitive performance, blood lipids and body composition. The authors point to the distinctive interplay of EGCG, the amino acid derivative L-theanine and caffeine as what sets matcha apart from other teas.
đ Apple cider vinegar â from kitchen staple to research subject
Apple cider vinegar has been part of European cooking for centuries. Over the past two decades it has increasingly drawn the attention of nutrition science, largely on account of its principal component, acetic acid.
A very recent meta-analysis by Castagna et al. (Nutrients, 2025) assessed ten RCTs with a combined total of 789 participants. The pooled results showed statistically significant reductions in body weight, BMI and waist circumference â most noticeably in participants who were overweight or had metabolic conditions. A systematic review by Launholt et al. (European Journal of Nutrition, 2020) also gives apple cider vinegar a generally favourable tolerability profile.
âī¸ L-Arginine â substrate for nitric oxide
L-Arginine is a semi-essential amino acid that the body can produce itself when required. Biochemically, it serves as the substrate for the formation of nitric oxide (NO) in the endothelial cells that line the blood vessels â a molecule with a central role in vascular regulation.
The dose-response meta-analysis by Shiraseb et al. (Advances in Nutrition, 2022) analysed studies on systolic and diastolic blood pressure and observed dose-dependent effects. An earlier meta-analysis by Dong et al. (American Heart Journal, 2011), covering eleven double-blind placebo-controlled trials with 387 participants, reported mean reductions of â5.39 mmHg (systolic) and â2.66 mmHg (diastolic). An umbrella review by McRae (Journal of Chiropractic Medicine, 2016) brings this body of work together and places L-Arginine among the most thoroughly studied amino acid supplements available.
đĨ L-Carnitine â a transporter for fatty acids
L-Carnitine is a compound the body makes itself from the amino acids lysine and methionine. Its name goes back to the Latin carnis â “meat” â because it was first isolated from meat extracts. Biochemically, L-Carnitine carries long-chain fatty acids across the inner mitochondrial membrane.
A wide-ranging meta-analysis published in Clinical Nutrition ESPEN (2020) pooled 37 RCTs with a combined 2,292 participants. The data showed statistically significant reductions in body weight, BMI and fat mass â most clearly in adults who were overweight. A recent umbrella meta-analysis from 2025 has since confirmed these observations across several independent systematic reviews.
âī¸ Zinc â an essential micronutrient with authorised EU health claims
Zinc is an essential trace element and acts as a cofactor in more than 300 enzymes involved in human metabolism. Under Regulation (EC) No 1924/2006, the European Food Safety Authority (EFSA) has reviewed and authorised a number of health claims relating to zinc â see EFSA Journal, 2009; 7(9):1229.
Zinc contributes to normal macronutrient metabolism, contributes to normal fatty acid metabolism and contributes to normal acid-base metabolism. Under EU law, these claims may be used for foods and food supplements that deliver at least 15% of the NRV (Nutrient Reference Value) per daily portion. With 7 mg of zinc, Wego6 covers 70% of the NRV and comfortably exceeds that threshold.
âšī¸ Notes on the research and the EU health claims
For spirulina, matcha, apple cider vinegar, L-Arginine and L-Carnitine there are currently no health claims authorised under Regulation (EC) No 1924/2006 in the EU. The studies cited here set out the present state of research and document promising findings, but they do not permit any claims in the regulatory sense. The effects reported also relate to the doses used in the respective trials, which in some cases exceed the amount contained in Wego6.
Wego6 is a food supplement, not a medicine. Food supplements are not a substitute for a balanced, varied diet or a healthy lifestyle. If you have an existing medical condition or take medication on a regular basis, please speak to your doctor before taking your first capsule.
