The objective of this study is to test the effect of 12 weeks of supplementation SRW Ndo1 on metabolic health and general health in adults with prediabetes. The primary question it aims to answer are:

• How does SRW Ndo1 affect the Haemoglobin A1C (HbA1C) test outcome for adult individuals?
• How does SRW Ndo1 affect the body measures and blood pressures of adult individuals?

Investigators will compare the supplement to a placebo (a look-alike substance that contains no supplement) to see if SRW Ndo1 works to support normal blood sugar metabolism.

Participants will:

• Take supplement SRW Ndo1, two capsules a day for 12 weeks.
• Be asked to refrain from changing their diet and lifestyle drastically during the study and to refrain from starting new health supplements during the study.
• Visit the clinic at the start and the end of intervention for a blood test (8 hour fasting required prior to test)
• Keep a diary of their symptoms or adverse events during intervention.
