Osteoporosis and natural remedies: Fish oil containing EPA (eicosapentaenoic acid) and GLA (gamma linolenic acid) is not only an effective safeguard against osteoporosis, it also improves the skin and brain function and avoids cardiovascular problems. Light exercise is also recommended, such as dancing, walking, or bouncing on trampolines. On that note, we misrepresented the suggestions of one reader last week by foolishly suggesting that natural progesterone cream was available at Argos when, in fact, it was a version of the rebounder she also recommended. Fulsome apologies to her and to all of you who queued at Argos in vain. Calcium and magnesium supplements, in the ratio of 2 or 3: 1 respectively, would also help increase bone density.
