Every Ingredient, Explained

One of the things that stands out about Purisaki is that the ingredient list is fully disclosed — no "proprietary blend" hiding doses. Here is every botanical extract in the formula, what it is, and what the research currently shows.

Core Active Ingredients

• Berberine Extract

  The headline ingredient. Berberine is a plant alkaloid found naturally in barberry, goldenseal, and Oregon grape. It has been studied extensively for its role in supporting healthy glucose metabolism and insulin sensitivity. Over 3,000 peer-reviewed studies reference berberine — making it one of the most researched botanical compounds in metabolic wellness.
• Fucoxanthin Extract

  A marine carotenoid extracted from edible brown seaweeds. Early clinical research suggests fucoxanthin may support healthy body composition, particularly around the abdominal area. Most robust data comes from studies in Japan. Research is still emerging, but the compound shows meaningful promise.
• Pomegranate Extract (Punicic Acid)

  Cold-pressed from pomegranate seeds, punicic acid is a conjugated fatty acid with strong antioxidant properties. It helps neutralise free radicals and has been linked in early studies to supporting healthy lipid profiles. Used in traditional Persian and Ayurvedic medicine for centuries.
• Green Tea Leaf Extract (EGCG)

  One of the most studied botanical extracts in the world. The key active compound EGCG (epigallocatechin gallate) is linked to natural thermogenesis support and sustained energy. Green tea extract is well-tolerated and has a strong safety record across hundreds of clinical studies.

Supporting Botanical Extracts

• African Mango Seed Extract (Irvingia gabonensis)

  Derived from the seeds of a West African wild mango tree. Early controlled trials suggest it may support healthy appetite regulation and leptin sensitivity. Research is limited but promising; more large-scale human data is needed.
• Ginger Root Extract

  A cornerstone of Ayurvedic and Traditional Chinese Medicine for over 2,000 years. Ginger supports healthy digestion, reduces occasional bloating, and has a well-documented antioxidant and anti-inflammatory profile.
• Cinnamon Bark Extract

  Beyond its use as a spice, cinnamon bark contains cinnamaldehyde and polyphenols associated with supporting healthy blood sugar balance. Several small trials suggest it may help moderate post-meal glucose spikes.
• Bitter Orange Peel Extract

  Contains synephrine, a naturally-occurring compound related to ephedrine but milder. Used traditionally as a digestive bitter. It may support metabolic rate at rest. Current research suggests it is safe at doses typically found in wellness products.

Essential Micronutrients

• Vitamin C (Ascorbic Acid)

  A powerful antioxidant essential for immune function, collagen synthesis, and iron absorption. Also helps protect the botanical extracts in the formula from oxidative degradation.
• Vitamin B1 (Thiamine)

  Essential for converting carbohydrates into usable energy. Deficiency is associated with fatigue and poor concentration. A sensible micronutrient addition to any metabolic support formula.
• Vitamin B3 (Niacin)

  Plays a central role in energy metabolism through its role in NAD+ production. Also supports healthy cholesterol balance and skin barrier integrity — relevant for a transdermal product.
