*Our Slim Me drinks contain glucomannan. Glucomannan can support weight management when taken alongside an energy-controlled diet, and support the maintenance of normal blood cholesterol levels. This beneficial effect is obtained with a daily intake of 3g of glucomannan in 3 doses of 1g each together with 1-2 glasses of water before meals.

Glucomannan (with Real Sicilian Lemon Oil): Glucomannan* is a water-soluble dietary fibre extracted from the konjac root. This fibre naturally suppresses your appetite by helping you feel fuller. This fibre can support weight management when taken alongside an energy-controlled diet.
Vegan Algae Oil: Our Omega-3 comes direct from the source; algae! We’ve cut out the middle-man (middle fish really) and that means our Omega-3 is vegan and more sustainable than other forms. DHA and EPA Omega-3 fatty acids help to maintain normal brain function, heart health, blood pressure and cholesterol levels.
Organic Turmeric: Long-hailed for its health benefits in Eastern medicine, this golden superfood is a great addition to a healthy lifestyle.
Purple Superberries: Our GP Gold drink contains Acai berry, Aronia and Bilberry. These berries get their vibrant colours from the phytonutrients (plant compounds) within them and are a source of Vitamin C; a vitamin which contributes to the protection of cells from oxidative stress and supports reduction of tiredness and fatigue.
Green Tea:The health benefits of green tea are renowned world over, and incorporating it into your lifestyle through enjoying it as a hot drink or as a supplement can help you reap these benefits.
