Learn more about supplements and how to use them

Supplements are different than over-the-counter medicines because medicine is given to change the physiologic workings of the body-suppress cough, decrease mucus, dampen inflammation-whereas supplements are typically given to enhance the normal functioning of the body, or to promote the optimal expression of body and mind. Here are the four basic types of supplements, with information on how to take them.

Food-like supplements, including vitamins, minerals and botanicals

In general, it's best to take these supplements with meals, which allows the entire digestive system to work on breaking them down, enhancing their effectiveness and reducing chances of a sour stomach.

Look for a multivitamin/mineral product that doesn't have a lot of unpronounceable words in the "inactive ingredient" list. And test it out. If your supplement doesn't dissolve completely within two hours of being placed in a small glass of vinegar, it won't break down in your stomach like it should.

Unless you're a strict vegan or vegetarian, or have an iron deficiency, you probably don't need iron supplements. But if you do need iron, uptake can be improved by taking it with vitamin C. This vitamin comes in many forms, but I prefer a non-GMO source such as organic corn, tapioca, or acerola cherry. Many vitamin C products are, unfortunately, derived from GMO corn, and although there is no genetic material from the corn in the C supplement, you are still supporting the GMO industry buying the standard corn-based vitamin C pills and powders.

Herbal medicines are, on the whole, extremely safe. There are a few herbs that can pose problems if taken at high doses, but they aren't widely available. A few other herbs also come with limited cautions. For instance, St. John's wort (Hypericum perfoliatum) can cause a rash in people who live in northern climates and visit very sunny places. Called "solar urticaria," this condition goes away if you stop taking the herb for two to three days, and it doesn't cause residual problems. Theoretically St. John's wort can cause "serotonin syndrome" if taking along with high dose SSRIs or SSNIs (pharmaceutical anti-depressants) but I've never seen this in 30 years of clinical practice. In fact, when helping folks wean off pharmaceutical anti-depressants (which needs to be done very slowly and with medical supervision) I not infrequently use St. John's wort in the step-down protocol very effectively.

Ginkgo is reputed to be a blood thinner and may enhance blood-thinning effects if you take it with pharmaceutical blood thinners like Plavix, Coumadin, aspirin, but it won't cause you to bleed out in surgery. It will improve your memory and your peripheral circulation, however, which helps with erectile dysfunction and cold hands and feet.

Licorice (Glycyrrhiza glabra) supposedly puts people at risk for high blood pressure due to its diuretic, and thus potentially potassium-wasting effects. But I have never seen this actually happen. Licorice is a potent adrenal support medicine, an antiviral, and an effective restorative herb for poor tone in the lower esophageal sphincter, which is almost always the problem in cases of heartburn.


Antibiotics wreak havoc on our gut flora, which includes H. pylori in the stomach (a balanced amount is normal); Lactobacillus acidophilus at the top of the small intestine; and Bifidobacteria in the colon. It's generally a good idea to take a broad-spectrum probiotic product for a month after taking antibiotics. And take probiotics right before eating a meal, which helps the friendly bacteria make its way to the intestines before stomach acid can compromise its viability.

I also recommend trying a variety of probiotic brands. The science of probiotics is highly complex, and scientists have yet to understand which bugs are best for you as an individual. So, it doesn't hurt to find out which ones make you feel better, improve your digestion, brighten your skin, etc.

My preferred probiotic is fermented foods like kimchee, sauerkraut, pickles, kombucha.


Most common enzymes are named after the substance they digest. Amylase digests amyl (starch), and protease digests protein, lipase digests lipids (fats) and lactase digests lactose (the sugar in dairy products). If you have digestive difficulties such as constipation, gas, bloating, or abnormal stools, digestive enzymes, taken with meals, can help. If they don't help, please consult with a nutrition-savvy doctor.

Enzymes also help with immunity. Your immune system's white blood cells contain enzymes called lysosomes, which "lyse" (break open) when they reach an area of infection or injury. These enzymes "digest" viruses, bacteria or irritated tissue so that the debris can be expelled from the body.

High-potency proteases (protein-digesting enzymes), taken without food, are my favorite remedy for most any type of "itis," including tendinitis, laryngitis, and adhesive capsulitis (bum shoulder). I often recommend a 10-day course of 1,000 mg of bromelain (a strong protein-digesting enzyme derived from pineapple), twice per day: first thing in the morning (half hour before breakfast) and last thing at night (at least two hours after dinner). Adding turmeric (1/4 – ½ tsp) improves the anti-inflammatory potential.

In short, just remember that if you need digestive help, take enzymes with food. If you need tissue repair or immune support, take enzymes several hours away from food.

Homeopathic remedies

The true study of homeopathy is a lifelong pursuit that requires a deep understanding of the "strange, rare and peculiar" aspects of each patient. However, the tiny white pellets that are available at health food stores can be extremely helpful for various common conditions. A few to try: Sarsaparilla for bladder infections; Ignatia for menses-related "blues"; Belladonna for flushing and right-sided headaches; Lycopodium for excessive gas; and Arnica for garden-variety bumps and bruises.

Homeopathic medicines are fragile. Take them with water only. Afterward, wait at least 15 minutes before eating and drinking, or using perfumes, hair products, toothpaste, or herbs. Avoid mentholated substances (e.g., Tiger Balm, Vicks VapoRub) because the strong menthol can be highly disruptive, and will "antidote" a homeopathic remedy, causing symptoms to re-emerge.
