Making Strong Bones and Joints

It strikes me as rather interesting that there is a force that moves us up, in opposition to gravity that takes us down. Plants reach towards the sun, building fibrous stems to do so, and so do we, building bone and connective tissue. We are no less dependent on sunlight than plants.

The Homocysteine Connection

One interesting discovery is the link between homocysteine, low B12 levels and bone and joint health. Over the last five years, there have been more and more studies linking high homocysteine and low B12 levels to increased risk of fractures, osteoporosis and decreased bone mass density, particularly in women. It looks as if homocysteine actually damages bone by encouraging its breakdown and interfering with the collagen matrix which is what holds bone together. Collagen is made from vitamin C, which is yet another reason why I recommend a daily intake of 1000mg taken twice a day.

High homocysteine levels are linked to most inflammatory diseases since homocysteine promotes the release of pro-inflammatory agents in the body. Homocysteine levels are frequently found to be much higher in rheumatoid arthritis sufferers as well as those with ankylosing spondylitis, which is an inflammatory arthritic disease of the spine. Since rheumatoid arthritis is a ‘systemic’ disease, where the whole body’s chemistry is out of balance and many tissues and organs other than the joints are affected, one would suspect that homocysteine plays a leading role in the disease. And it does.

Research from the Department of Biochemistry at the University Hospital in Madrid, Spain, examined the homocysteine scores of women with rheumatoid arthritis versus those without. There was a massive difference. The average homocysteine score for those with rheumatoid arthritis was a sky-high 17.3, compared to 7.6 for those without! Other research groups have found similar differences, especially among rheumatoid arthritis sufferers with a history of thrombosis or abnormal clotting of the blood.

Homocysteine is now thought to damage joints and other tissues directly. All of this suggests that reducing homocysteine may well help keep your bones and joints healthy. Yet, disappointingly, very little research has yet been done to test the homocysteine theory on arthritis. An exception occurred in 1994 when forward-thinking researchers from the highly esteemed American College of Nutrition in Clearwater, Florida, gave B12 and folate supplements to 26 people who had been suffering from osteoarthritis of the hands for an average of more than five years, and had been taking non-steroidal anti-inflammatory, pain-relieving drugs (NSAIDs).

B12 and folate work together to help reduce high homocysteine levels. The results showed that people with arthritis who took the vitamins in place of the NSAIDs had less tenderness in their hand joints, and similar improvement in their ability to grip objects, compared with those just taking NSAIDs, but suffered none of the notorious side-effects seen with the use of these drugs. NSAIDs can cause serious reactions, including premature death from kidney failure, ulcers and bleeding in the digestive tract, and they cost considerably more than B12 and folate supplements. As many as two in five people over 60 are B12 deficient, if tested, and the lowest level that corrects B12 deficiency is 500mcg a day. While fish, meat, eggs and milk all contain B12, only milk and fish consumption are linked to increasing blood B12 levels, possibly indicating that these foods have more bioavailable B12. Even so, you are unlikely to get more than 3mcg of B12 from your food. Most B12 experts think that we could all benefit from a daily intake of 10mcg which is the minimum I’d recommend in a good multivitamin. B6, another homocysteine-lowering vitamin, has also proven helpful for arthritis sufferers.
