About six months ago, the pressures in my eyes were 22 mmHg (left) and 21 mmHg (right). The optician told me I should have my pressure tested every six months, as I was in danger of developing glaucoma.

Less than three months ago, I discovered that alpha-lipoic acid was protective against glaucoma and could reduce the pressure in my eyes. After taking one capsule a day for six weeks, I noticed a marked improvement in my eyesight. After taking the tablets for two and a half months, sure enough, the pressure has gone down to 20 mmHg (left) and 18 mmHg (right). - Patricia Knox, Holyhead

WDDTY replies: Alpha-lipoic acid, or ALA, is a potent antioxidant (far more so than vitamins C and E) that increases glutathione (for cellular energy and proper immune function), and helps all conditions due to increased insulin production and abnormal glucose metabolism, including diabetes, high cholesterol, glaucoma, cataracts and hardening of the arteries. Research has demonstrated its effectiveness in treating glaucoma (Vest Oftalmol, 1995; 111: 68) and cataracts (Ann NY Acad Sci, 1994; 738: 257-64). The usual dose is 50-100 mg twice a day; higher dosages can cause nausea, upset stomach and even low blood sugar. Its presence in greens, such as spinach, accounts for the Popeye effect (see WDDTY vol 15 no 3’s special report). It’s also found in liver and brewer’s yeast.
