MSPs are still considering a schoolboy's petition for children and pregnant women to be given free Vitamin D supplements.
14-year-old Ryan McLaughlin, from Drumchapel, submitted his request to the Scottish Parliament after watching his mother suffering from multiple sclerosis.
On Tuesday, he appeared in front of MSPs on the Petition's Committee. They asked the teenager for more information before deciding on the measure.
Ryan has captured the imagination of the public with his enthusiastic campaigning on the issue of MS.
Some experts believe Vitamin D can help to prevent the muscle wasting disease, and the 14-year-old has already been backed by 200 supporters, including Harry Potter author JK Rowling.
Ryan lodged a petition at Holyrood in June, telling politicians: "I am Ryan McLaughlin and I have come here today because my mum has multiple sclerosis.
"It's too late for my mum - we are now waiting for a cure."
The Scottish Government told the campaigners in September that a vitamin D awareness campaign was under "active consideration".
Ministers also said they would issue new guidelines on the use of the supplement by children, pregnant and breastfeeding women. At the time, free vitamin D supplements for all pregnant and breastfeeding women were ruled out and the Government said it had no plans to introduce the supplements in the form of fortified milk at school.
However, the campaigners have described the Government response so far as "very supportive" and say they are hoping MSPs will take the issue further.
