Folic acid can be taken to prevent certain birth defects. Calcium and vitamin D may help avoid or treat bone loss and osteoporosis. Fish oil is effective for lowering high triglycerides. But what about all the other supplements that you hear so much about? Should you take echinacea, flaxseed oil or ginseng? Is it best to buy generic brands or synthetic supplements? Here are a few tips about choosing and using supplements.

Dietary supplements are meant to add to your diet so you get the Recommended Dietary Allowance (RDA) for most of the 18 vitamins and minerals for which RDAs have been established. It is important to talk with your doctor before taking any dietary supplements because some can interact with medications, and may increase the risk of bleeding or response to anesthesia during surgery. Always read label instructions and take supplements in the proper dosage amount.

When buying supplements, keep in mind that generic brands or synthetic forms are usually cheaper and just as effective as name-brand or natural supplements. Be sure to check the expiration date and opt for products approved by the USP, NSF and ConsumerLab. This indicates that the supplement has passed tests to show it is free of contaminants, meets the label claim for strength of the product, and dissolves properly in the body.

If you are a runner, you may have heard of runner’s knee. But this common ailment that causes pain around the front of the knee also can affect skiers, cyclists, soccer players or any athlete who does activities that put heavy stress on the knees. The good news is that runner’s knee can be prevented and treated. The bad news is during recovery you’ll have to put away the running shoes for a while.

Runner’s knee actually refers to a number of medical conditions that can be caused by misalignment of the kneecap, overuse, injury, weak thigh muscles or flat feet. Symptoms typically include popping or grinding sensations in the knee, pain behind or around the kneecap, pain when bending the knee, and pain that worsens when walking downstairs or downhill. The condition can be diagnosed following a physical examination, as well as X-rays, magnetic resonance imaging or computed tomography scans.

Treatment for runner’s knee starts with discontinuing the activity that causes knee pain. Minor to moderate cases should heal over time when combined with rest, ice, compression and elevation. Anti-inflammatory painkillers may be recommended to help with pain and swelling.

It is important not to rush back to activities before the knee has healed. To prevent the condition from recurring or avoid it in the first place, keep thigh muscles strong and limber, use orthotics for flat feet, make sure shoes have good support, avoid running on hard surfaces, maintain a healthy weight, wear a knee brace if you have had runner’s knee before, stretch before exercising, and increase training gradually.

Your target heart rate is the range at which sustained physical activity is considered safe and effective. The ideal range, which is a percentage of what your maximum heart rate should be, depends on your age and how physically fit you are. It is important to know this because regular exercise can help you stay healthy and maintain a normal weight.

You can estimate your heart rate during exercise by briefly stopping to find your pulse on your neck or wrist. Place two fingers on either of these locations and press lightly. Count the number of beats for a full minute, or for 30 seconds and double the result. You also can buy an inexpensive pulse monitor at the store.

A 40-year-old, for example, has an estimated target heart rate of 90 to 135 beats per minute. Results will vary by each individual depending on their physical condition and age.

Even if you aren’t ready to run a marathon, you can improve your fitness with a 30- to 60-minute workout of moderate intensity most days of the week. Beginners should start at a less vigorous level and work up to a moderate intensity. If you have any heart problems, or if you are elderly, consult with your physician before starting a rigorous exercise program.

Check your target heart rate with the free, online Target Heart Rate Calculator on the Doctors Hospital at White Rock Lake website at www.DoctorsHospitalDallas.com/TargetHeartRate.
