Healthy eating and regular exercising are both proven to be beneficial for bone health. We can also use supplements available at natural health stores to help keep our bones and joints strong and working well. Calcium is an essential mineral for bone building. The daily adequate intake (AI), according to Health Canada, is between 1,000 and 1,300 mg for adult men and women. Calcium supplements are best absorbed in divided doses, one to one-and-a-half hours after meals. A liquid form of calcium citrate may be more easily absorbed and utilized than calcium carbonate solid tablets or capsules. Vitamin D in sufficient amounts is required for our skeletal system to properly absorb calcium. The daily AI for vitamin D is between 200 and 600 IU for people over age two. Magnesium, along with vitamin D, allows our bodies to absorb calcium. It also aids in the prevention of calcification of soft tissue. Health Canada’s RDA is between 310 and 320 mg for adult females and between 400 and 420 mg daily for adult males. Glucosamine sulphate may help repair the normal wear and tear on joint cartilage. Adults can take up to 1,500 mg daily and should notice a difference in the ease of motion in their joints within two weeks to three months. There is evidence to support the use of glucosamine as an adjunct therapy in treating osteoarthritis. Chondroitin sulphate has a beneficial effect on joint function and mobility and may allow decreased use of anti-inflammatory drugs when used for six to 24 months. Adult daily dosage is 200 to 400 mg, two to three times daily; 800 to 1,200 mg once-daily doses have been used in some medical studies. Evening primrose oil is a source of gamma-linolenic acid (GLA) that can help maintain healthy joints. To maximize relief from symptoms of arthritis, start with four 1,000 mg capsules of evening primrose oil with a meal. The daily dosage may be increased to up to 10 capsules a day. It may take one month of supplementation to realize the full benefits. Omega-3 fatty acids in some fish, algae, and plant oils help to maintain joint flexibility and mobility. They also lessen stiffness, swelling, and tenderness in joints without any short–or long-term side effects. These benefits are attributed to the fatty acids EPA and DHA. A combination of EPA and DHA–up to 3 g daily–is recommended to reduce pain and inflammation. Vitamin K helps strengthen bones and prevent osteoporotic fractures. A healthy adult male’s AI for vitamin K is 120 mcg daily; for adult females it’s 90 mcg daily. People on prescribed blood thinners should seek their health care professional’s advice before taking vitamin K as it can interfere with these medications. High-quality supplements ensure that bone-building and strengthening vitamins and minerals are readily available and easily absorbable. Tablets containing poor-quality excipients, such as binders, fillers, and coatings, can alter the absorption of active ingredients. Knowledgeable staff at your favourite health food store can recommend high-quality products.
