Juvel 5 silhouette direct ingredients

L-carnitine Carnipure : This L-carnitine is produced by Lonza Laboratories, whose experience and expertise are unquestionable.

L-carnitine plays a fundamental role in the transport of fatty acids across cell membranes, resulting in optimal fat breakdown and energy production. Lonza L-Carnitine also has 4 certifications:
– ISO 9001:2008 and FSSC 22 000 (ISO 22 000 + PAS) certified;
– Certified Kosher and Halal ;
– Allergen-free;
– Total traceability.

L-glutamine : this amino acid also optimizes energy production from proteins and carbohydrates, limiting the accumulation of fat and unsightly curves. It also helps reduce sugar cravings.

L-arginine : L-arginine triggers the release of growth hormone, a hormone that promotes fat burning, strengthens muscle tissue and protects the body from aging.

Wolf berry extract : Wolf berry is another name for the Goji berry, to which we have devoted a complete article HERE.

This little fruit is packed with antioxidants, trace elements, vitamins and minerals, and contributes to overall good health. Rich in fiber and with a low glycemic index, it helps reduce sugar cravings in particular.

Trace elements : Juvel 5 silhouette direct contains magnesium, which plays a fundamental role in the processes underlying energy production.

It is also the trace element of stress, one of the main sources of weight gain; selenium, which combats oxidative stress and free radicals, strengthens the immune system and is involved in the proper function of the thyroid; zinc, which is involved in the metabolism of sugars, fats and proteins, and in the proper functioning of the immune system.

Vitamins B vitamins: Juvel 5 silhouette direct contains B vitamins (B1, B2, niacin, B6, B12, B5, B9 and B8), which are important for various metabolisms (carbohydrates, lipids, proteins), appetite regulation and the conversion of fatty acids into energy.

Juvel 5 silhouette direct and science

In 2 different studies, subjects were given fatty acids with their meals, before and after 10 days’ supplementation with Carnipure® L-Carnitine.

The L-carnitine group showed a significant increase in the oxidation of ingested fatty acids.

Furthermore, in combination with a low-calorie diet and moderate physical activity, L-Carnitine improved weight loss in obese subjects, as well as lowering LDL, blood sugar and blood pressure.

This study is available on the official website of Lonza.

The studies on L-arginine are also very interesting. In the first study, participants consumed L-arginine supplementation for 21 days, in addition to following a low-calorie diet and exercise routine.

L-arginine significantly increased the production of adiponectin, a hormone with the ability to inhibit fat storage (Source: Am J Physiol Endocrinol Metab. 2006 Nov;291(5):E906-12. Epub 2006 Jun 13. Beneficial effects of a long-term oral L-arginine treatment added to a hypocaloric diet and exercise training program in obese, insulin-resistant type 2 diabetic patients.)
Finally, another study on the slimming effects of L-arginine showed that after 18 months of supplementation with 6.4g of L-arginine per day, obese subjects saw their body composition improve (less fat mass, more lean mass) as well as their insulin sensitivity.
