Iron & Alginate Study

After insertion of the cannula and collection of baseline blood sample a single dose of approximately 20mg of iron as ferrous gluconate incorporated into alginate beads (approximately 22.2g)and added to cola jelly (200ml) will be given to the volunteer together with 3 placebo capsules (each containing 50mg of dextrose)and cola drink (200ml). Once consumed, further blood samples will be taken at specified time points during 6 hour cannulation time. A minimum of 7 days wash out period will take place prior next intervention.

After insertion of the cannula and collection of baseline blood sample a single dose of approximately 20mg of iron as ferrous gluconate in a capsule and 2 placebo capsules (each containing 50mg of dextrose) followed by a cola jelly (200ml)and cola drink (200ml) will be given to the volunteer. Once consumed, further blood samples will be taken at specified time points during 6 hour cannulation time. A minimum of 7 days wash out period will take place prior next intervention.

After insertion of the cannula and collection of baseline blood sample a single dose of approximately 20mg of iron as ferrous gluconate in a capsule together with 2 calcium capsules (each containing 300mg of calcium phosphate)followed by cola jelly (200ml) and cola drink(200ml)will be given to the volunteer . Once consumed, further blood samples will be taken at specified time points during 6 hour cannulation time. A minimum of 7 days wash out period will take place prior next intervention.
