Sensitive joints are now a thing of the past

Sigríður has noticed a huge difference since she started taking Liðir from Protis. The morning stiffness in her ankles and sensitive joints are now a thing of the past and she can, in her own words, “do whatever she wants.”

“I started taking collagen because I was getting older and wanted to try it. I’m turning sixty and had started to feel it in my joints, and I also have underlying lupus, which is an autoimmune disease,” says Sigríður Svava Þorsteinsdóttir, who works as a medical laboratory scientist at Landspítali University Hospital.

“I have been actively involved in sports all my life and kept myself in good shape. I exercise daily and since I work shifts and my job is physically demanding, it’s important for me to be in good shape.”

Nothing to lose

“Stiffness comes with age and when I got up in the morning, my ankles were crackling and stiff. A colleague at work told me about Liðir and I thought, what do I have to lose? I’ll try it,” says Sigríður.

“I’ve been taking Liðir for about a year. I notice a big difference from when I didn’t take it. The stiffness has decreased a lot. I don’t feel the sensitivity in my joints that I used to feel. I can jump around as I please,” she says cheerfully.

Still exercising daily

“I’m still exercising every day. I work in intensive care so I’m often very tired after work. Now I have more energy and recovery is faster. The crackling in my joints has decreased a lot. I use Liðir together with collagen and I’ve been very satisfied,” says Sigríður.
