After an 8-10 hour overnight fast, Group A will receive two soft capsules of TPGS (400mg) emulsified berberine. Following a 7 day wash out period, Group A participants will then receive four capsules of the Quillaja extract emulsified berberine (200mg). Following another 7 day wash out period, Group A participants will then receive two hard shell capsules of the berberine reference powder 400mg. Each TPGS and berberine reference powder capsules contains 400 mg berberine. Each Quillaja extract capsule contains 200 mg berberine. The total amount of berberine throughout is 800 mg.

After an 8-10 hour overnight fast, Group B will receive four soft capsules of Quillaja extract emulsified berberine (400mg). Following a 7 day wash out period, Group B participants will then receive two hard shell capsules of the berberine reference powder (400mg). Following another 7 day wash out period, Group B participants will then receive two soft gel capsules of TPGS emulsified berberine (400mg). Each TPGS and berberine reference powder capsules contains 400 mg berberine. Each Quillaja extract capsule contains 200mg berberine. The total amount of berberine throughout is 800 mg.

After an 8-10 hour overnight fast, Group C will receive two hard shell capsules of the berberine reference powder (400mg). Following a 7 day wash out period, Group C participants will then receive two soft gel capsules of TPGS emulsified berberine (400mg). Following another 7 day wash out period, Group C participants will then receive four capsules of the Quillaja extract emulsified berberine (200mg). Each TPGS and berberine reference powder capsules contains 400 mg berberine. Each Quillaja extract capsule contains 200mg berberine. The total amount of berberine throughout is 800 mg.
