When it comes to managing high blood pressure, the average American consumes too much sodium and too little potassium. Reversing this imbalance could help control high blood pressure which could, in turn, lead to fewer heart attacks, strokes, and deaths from heart disease.

In November 2022, the FDA called out seven supplement companies for illegally claiming their products could treat or prevent cardiovascular disease, such as atherosclerosis or heart failure.

A 2022 study found that a statin drug lowers LDL cholesterol better than six popular dietary supplements. While not everyone with high LDL needs a statin, these drugs are proven to lower heart attack risk in people who have or are at high risk of heart disease based on a common risk calculator. Dietary supplements such as cinnamon, garlic, and turmeric aren't helpful for addressing heart-related risks, and product labels often offer false promises regarding cardiovascular benefits.

Statins were more effective at lowering cholesterol levels compared with six dietary supplements touted for heart health benefits, including managing cholesterol.

A 2022 study found that taking supplements for four weeks to treat "bad" LDL cholesterol was ineffective, compared with taking a statin drug for four weeks. Supplements studied included fish oil, cinnamon, garlic, turmeric, plant sterols, and red yeast rice.

A 2022 study found that women ages 35 to 69 who ate vegetarian diets were significantly more likely to break a hip than peers who ate fish or meat. Vegetarians need to be sure they get adequate amounts of dietary protein, calcium, vitamin D, and other micronutrients to maintain bone health.

Over-the-counter supplements touted to support prostate health are popular, and supposedly help prevent and manage symptoms of an enlarged prostate (benign prostate hyperplasia). Some of the ingredients are said to protect against prostate cancer or slow its growth. While research has explored supplements' role in prostate health and some had positive results, the findings are far from conclusive. A better dietary option for prostate health is to follow a plant-based diet like the Mediterranean or DASH diet.

Many people have misconceptions about avoiding heart disease. One involves the use of over-the-counter fish oil capsules, which do not prevent heart disease in healthy people. Another relates to confusion about the ideal blood pressure targets in older adults. Some people are misinformed about the implications of a family history of heart disease, while others may be confused about the differences in heart attack symptoms between men and women.

Digestive enzyme supplements are promoted to fix problems like bloating, gas, and bowel irregularity. However, for most people, there's little evidence that they help. Doctors may prescribe enzyme pills for people who can't make enough digestive enzymes because of a health condition.

A 2022 study found that low blood levels of vitamin D (under 25 nanomoles per liter) were linked with higher risks of dementia. People can boost vitamin D levels from diet, supplements, or sun exposure.
