* Easy To Understand Summarised Scientific Studies *

The Science Behind The Ingredients In Complete Belly Reset

  • Collagen is 36% more filling than other proteins, which can reduce sugar cravings, snacking and overeating. Collagen is also known for making skin smoother and reducing wrinkles and fine lines. Plus, it helps improve bone and joint health.

  • With 137x more antioxidants than green tea, Matcha is high in L-theanine, an important amino acid found in tea that promotes a state of deep relaxation and well-being. Studies suggest that L-theanine may also have antibacterial benefits and help enhance cognitive power.

  • Prebiotics help power good bacteria while crowding out the bad ones. This helps reduce symptoms associated with yeast overgrowth, helps with nutrient absorption and can prevent mood disorders by working at the gut-brain axis.

  • Magnesium Glycinate improves the quality and duration of sleep - including sleep onset latency. More restorative rest means the body has more time to repair cells resulting in strong, healthy, and beautiful nails and hair.

  • Broccoli sprouts are abundant in important vitamins, minerals and nutrients including: Gallic, chlorogenic, ferulic, sinapinic, benzoic and salicylic acids, quercetin, kaempferol, dietary fiber, pantothenic acid, vitamin B6, vitamin E, manganese, phosphorus, choline, vitamin B1, vitamin A (in the form of carotenoids), potassium and copper.

  • Skullcap Root assists the nervous system in regulating signs of anxiety and promoting natural relaxation. It also contains anti-inflammatory properties which protect cells from damage and can reduce the pain of those suffering from IBS or arthritis.

  • Alfalfa sprouts can help women minimize symptoms related to menopause and menstruation. Rich in Vitamin K, a blood-clotting vitamin, it can help reduce excessive bleeding that can lead to painful cramps. The combination of vitamin K and phytoestrogens also has an effect on regulating estrogen in women of all ages.

  • When combined with Vitamin A, Carotenoids help prevent skin cancer and premature skin damage. Diets high in carotenoids help prevent wrinkles, drying and aged-looking skin. Vitamin A also helps prevent keratinisation of the skin which is a process that causes your cells to lose their moisture and become very dry.
