What it is: Tonalin®-CLA is a stimulant-free, patented conjugated linoleic acid (CLA) softgel formula developed by DaVinci Labs, delivering 800 mg of Tonalin® brand CLA per softgel from a high-quality safflower oil source. Tonalin® is an exclusively licensed CLA ingredient produced by BASF Personal Care and Nutrition GmbH under U.S. Patents #5,428,072, #5,554,646, and #5,430,066 — the most clinically studied form of CLA available in the supplement market, with an extensive body of human research supporting its role in body composition modulation. Free of stimulants and filler ingredients, Tonalin®-CLA is designed for practitioner-directed use in weight management, body composition, and cardiometabolic support protocols, and is noted as a compatible adjunct to GLP-1-based weight management programs.
How it works: Tonalin®-CLA supports body composition through several well-characterized mechanisms involving fat cell metabolism, lean muscle preservation, and cardiometabolic regulation. CLA (conjugated linoleic acid) is a naturally occurring polyunsaturated fatty acid primarily found in meat and full-fat dairy products, and is also produced endogenously by Lactobacillus rhamnosus in the gastrointestinal tract — a production pathway that is frequently compromised by stress, antibiotic use, or dysbiosis, making exogenous supplementation clinically relevant for many clients. At the cellular level, CLA promotes the apoptosis of mature adipocytes and inhibits the differentiation of preadipocytes into new fat cells, effectively reducing the formation of new fat deposits while simultaneously stimulating the mobilization of existing fat stores — returning free fatty acids to the bloodstream where they are preferentially utilized as energy substrate by muscle cells and the liver. This dual fat-reducing and energy-repartitioning mechanism supports a favorable shift in body composition toward reduced fat mass and preserved or increased lean muscle tissue — an outcome not typically achieved by caloric restriction alone, which tends to reduce both fat and lean mass proportionally. Additionally, CLA supports the maintenance of blood glucose, triglycerides, and cholesterol within normal ranges through its activity on PPAR-gamma nuclear receptors and insulin receptor signaling pathways, contributing to broader cardiometabolic health support alongside its body composition benefits.
When to use it: Tonalin®-CLA is appropriate for practitioner-directed use in adult clients pursuing fat mass reduction, lean muscle preservation, and cardiometabolic support as part of a comprehensive weight management or body composition protocol. It is particularly well-suited for clients engaged in resistance training or exercise programs where lean muscle maintenance during a caloric deficit is a priority, for those participating in GLP-1-based weight management programs, and for clients with cardiometabolic risk factors where healthy triglyceride, cholesterol, and blood glucose levels within normal ranges are clinical objectives. The recommended dose of one softgel three times daily with meals supports consistent CLA availability throughout the day and optimizes absorption alongside dietary fat.

Key Ingredients
Tonalin® Brand CLA (Conjugated Linoleic Acid) — 800 mg Tonalin® is a patented, exclusively licensed conjugated linoleic acid ingredient produced by BASF Personal Care and Nutrition GmbH (U.S. Patents #5,428,072, #5,554,646, and #5,430,066), derived from high-quality safflower oil and representing the most extensively clinically researched CLA form available — with a substantial body of peer-reviewed human trials supporting its role in body composition modulation. CLA is a naturally occurring polyunsaturated fatty acid that promotes adipocyte apoptosis and inhibits preadipocyte differentiation, simultaneously reducing the formation of new fat deposits and stimulating the mobilization of existing triglyceride stores for preferential use as energy substrate in muscle tissue and the liver. At 800 mg per softgel and 2,400 mg per daily serving (three softgels), Tonalin®-CLA delivers a clinically validated dose to support reduced fat mass, preserved lean muscle tissue, healthy body composition during caloric restriction or exercise programs, and maintenance of blood glucose, triglycerides, and cholesterol within normal ranges through PPAR-gamma and insulin receptor signaling pathway activity.
