I take a standard multi-vitamin, as well as additional calcium, but I really need to take more, I’ve just been too busy/lazy to research what my body needs to compensate for my hashimoto’s disease.
As for glucosamine, I can actually attest to its effectiveness based on my cat. She’s 21 and a couple of years ago started experiencing a little loss of strength in her legs. She had a harder time jumping up on the bed, sofa, chairs, etc, and would fall over mid-jump and land on her side. On the advice of her vet, we started giving her glucosamine and within a few weeks we saw a significant, noticable improvement. She’s been getting it daily for a couple years now and in all that time I’ve never seen her fall over trying to jump up on anything.
We’ve also seen a great improvement in her skin and coat since adding omega 3 fatty acids to her vitamin regimen, as well. Based on the very positive results we’ve seen her experience with these 2 supplements, I’ve been contemplating taking them, myself, since joint pain and dry skin and hair are among the symptoms I experience.
