What is a Dietary Supplement?

A dietary supplement is any product that you take orally which adds to the content of your ordinary diet. These products come in the form of pills, capsules, powders, gel tabs, extracts, and liquids. People take supplements for many different reasons: for weight loss or to gain muscle, to restore nutrients, to support functions like eyesight, to improve sleep, and to increase energy. Diet supplements typically contain a variety of ingredients including:

  • Vitamins
  • Minerals
  • Amino acids (protein building blocks)
  • Enzymes
  • Botanical products/herbs
  • Glandular extracts
  • Organ products

What's the Problem?

Dietary supplements do not require approval from the Food & Drug Administration (FDA) before they can be sold on the U.S. market, which means that consumers who fall prey to supplement advertising may be putting themselves at risk of injury. A study by JAMA Internal Medicine [1] found that dietary supplements accounted for more than 50% of the FDA’s Class I drug recalls from 2004 to 2012. Class I drugs are those that contain ingredients with a reasonable probability of causing “serious adverse health consequences or death.”

Our lawyers believe that supplement manufacturers should be held to a higher standard due to the severe potential health risks associated with the products they sell and must take responsibility for conducting ingredient research and voluntarily recall supplements when safety concerns arise.

While the potential health effects vary greatly from product to product, in general, dietary supplements increase the risk for the following types of injuries:

  • Heart disease/heart attack
  • Blood clots
  • Stroke
  • Kidney failure / renal disease
  • Neurological injuries
  • Liver damage
  • Sudden death
  • And more

Types of Diet Supplements

Most harmful dietary supplements fall into 3 main categories:

Pre-workout supplements - contain stimulants that increase heart rate and blood pressure, increasing the risk for acute cardiovascular injuries including heart attack and stroke.

Weight-loss pills - contain stimulants like ephedra which have been linked to severe cardiovascular injuries and death.

Testosterone boosters - Supplements that claim to increase testosterone levels, potentially improving sexual performance, libido, and muscle mass. Linked to severe heart and liver injuries.

Workout Supplements

Workout supplements -- sometimes referred to as “pre-workouts” -- are multi-ingredient dietary formulas designed to boost energy and athletic performance. Most of these products are powdered substances that you mix in water and drink before exercise, and include a wide variety of ingredients including amino acids, B vitamins, caffeine, creatine, and artificial sweeteners.

Unfortunately, people who take these and other similar pre-workout supplements on a regular basis may encounter serious physical drawbacks. It is important to understand that pre-workout supplements are not for everyone, and even worse, can have severe health effects if not used properly.

Some of the most popular pre-workout supplements include:

Pre-Workout Supplements Side Effects

  • Testicle shrinkage
  • Infertility in males
  • Breast enlargement
  • Masculinization of women (abnormal hair growth, missed menstruation)
  • Short stature in children
  • Acute liver injury
  • Kidney failure
  • Heart attack
  • Stroke
  • Adverse effects on blood lipid levels
  • Blood clots
  • Pulmonary embolism
  • Deep vein thrombosis
  • Death

What’s the Problem with DMAA?

Dimethylamylamine (DMAA) is a powerful stimulant that was contained in many popular pre-workout supplements, including OxyElite Pro and Jack3d, which has similar effects on the body as amphetamines. DMAA was originally marketed as a “natural” stimulant with many benefits including as a bodybuilding aid, athletic performance enhancer, and weight-loss drug. However, although DMAA was once approved as a nasal decongestant drug, no medical use for the substance is recognized today. Additionally, the FDA has found that no reliable studies indicate the substance exists naturally in plants. DMAA was finally banned in the U.S. in 2012 after being linked to multiple deaths.

DMAA Side Effects

  • Hyperthermia
  • Irregular heartbeat
  • Seizures
  • Heart attack
  • Stroke
  • Liver damage/liver failure
  • Kidney damage/kidney failure
  • Psychiatric side effects
  • Elevated blood pressure
  • Sudden cardiac death

GNC Fined $2.5 Million for DMAA in OxyElite Pro

GNC in Dec. 2016 agreed to pay $2.25 million to settle a lawsuit with the U.S. Department of Justice resolving allegations that the company marketed supplements that contained hidden drug ingredients. Per the settlement, GNC agreed to tighten regulations over the supplements it sells, remove products that contain illegal and unsafe ingredients, and keep a list of safe-to-sell products.

Please note that our lawyers are no longer accepting OxyElite Pro lawsuits.

What are SARMs?

Often touted as “legal steroids,” selective androgen receptor modulators, or SARMs, are unapproved and potentially adulterated dietary supplements that have been linked to serious side effects including liver damage, blood clots, heart attacks, and stroke. In July 2017, the U.S. Anti-Doping Agency (USADA) [2] issued a supplement warning on Ostarina, a trademarked SARM that has not been approved for use in the U.S., after authorities noted a significant increase in positive doping test results for the supplement.

Have you or a loved one been harmed by the side effects of a dietary supplement?

SARMs vs. Steroids

SARMs are similar to steroids in that both work by binding to androgen receptors, which trigger changes to the user’s DNA, increasing the muscles’ ability to grow. However, steroids affect other parts of the body, increasing the risk for serious side effects including prostate cancer, hair loss, and acne. SARMs, on the other hand, are said to be "tissue-selective" in that they target a person’s muscles without setting off the same dangerous chain of reactions. They're also taken in pill form, rather than injected.


Beta-methylphenylethylamine, or BMPEA, is a powerful stimulant found in many widely-used pre-workout supplements which have been linked to cases of hemorrhagic stroke and other serious side effects. BMPEA belongs to the phenethylamine family of chemicals, which also includes amphetamines and hallucinogens like mescaline. Although it is currently unknown specifically how phenethylamines react in the human body, they have been found to raise blood pressure and heart rates in laboratory animals. BMPEA is classified as a doping agent by WADA because it is chemically similar to amphetamine.

Diet Pills

Diet pills include prescription and over-the-counter supplements that are intended to help the user control their weight. These products work by interfering with body processes that affect weight by suppressing appetite, increasing metabolism, or preventing fat absorption.

Considering the epidemic of obesity and obsession with weight loss in the U.S., it’s no surprise that diet pills are widely available in multiple forms. Whether over the counter or prescription, each supplement carries its own significant potential health risks. Some of the most commonly abused diet pills include:

  • Didrex (generic: benzphetamine) - Amphetamine-like anorectic drug whose main function is to reduce appetite in obese individuals.
  • Tenuate / Tepanil (generic: diethylpropion) - Prescribed for short-term use to suppress appetite.
  • Mazanor / Sanorex (generic: mazindol) - Approved for use only to treat Duchenne muscular dystrophy; typically abused for its ability to suppress appetite.
  • Adipex / Lonamin (generic: phentermine) - Used short-term to reduce weight in overweight individuals. Works by curbing appetite.

Diet Pill Abuse

All diet pills contain a significant potential for dependence and addiction. The supplements cause increased energy and feelings of euphoria, increasing the risk for addiction. Other factors that may affect the development of a diet pill addiction include biological factors, environmental factors, home and family, peers and school, early use, and how the drug is taken.

Testosterone Boosters

Testosterone boosters are a class of herbal supplements and other compounds designed to increase sex drive or improve sexual function, muscle mass, sperm count, and body composition. The drugs work by replacing the testosterone that the body is not producing. Some of the most popular testosterone boosters include:

  • AndroGel
  • Androderm
  • Axiron
  • Bio-T-Gel
  • Delatestryl
  • Depo-Testosterone
  • Fortesta
  • Striant
  • Testim
  • Testopel

More than 25,000 lawsuits have been filed against the manufacturers of these products, alleging that the companies put healthy men in danger by marketing the hormones to treat sexual dysfunction, age-related fatigue, and other symptoms that go beyond the use approved by the FDA. Because of the large number of cases, the U.S. Judicial Panel on Multidistrict Litigation (JPML) created a testosterone multidistrict litigation (MDL) [3] in June 2014. As of June 2020, there were still nearly 3,500 product liability cases pending in the federal court system.

Our law firm has concluded our involvement in these lawsuits and was able to obtain settlements for our clients. Please note that we are no longer accepting cases on the testosterone supplements listed above. However, if you have been harmed by a testosterone-boosting supplement, you may have a case. 

Testosterone Side Effects

  • Stroke
  • Blood clots

  • Prostate cancer
  • Death

GNC Supplements

For decades, GNC has been one of the largest retailers of unregulated dietary supplements in the United States. A recent class-action lawsuit filed in California alleges that GNC’s sale of certain dietary supplements is illegal in that the products fail to contain a disclaimer stating they have not been approved by the FDA.

Specifically, the lawsuit contends that GNC misled, deceived, and profited off consumers by selling supplements with labels that lack a prominently displayed disclaimer that reads, “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”

GNC supplements named in the class action include:

  • GNC Men’s Prostate Formula Dietary Supplement (“Prostate Health”)
  • GNC Diabetic Support Dietary Supplement (“Diabetic Support”)
  • GNC Preventive Nutrition Healthy Blood Pressure Formula Supplement
  • GNC Women’s Ultra Mega Active Supplement
  • GNC Mega Men Healthy Testosterone (“Mega Men Performance”)

The lawsuit is RICHA ARORA, RANDY CLINTON, and WALTER JOHNSTON v. GNC HOLDINGS, INC. Case No. 3:19-cv-02414. U.S. District Court, Northern District of California.

FDA Regulation of Dietary Supplements

The Dietary Supplement Health and Education Act (DSHEA) [4] of 1994 classifies dietary supplements as foods, not drugs. The companies that manufacture these products are responsible for the supplements’ safety and health claims attached to them; however, they do not require approval from the FDA before marketing.

According to the DSHEA, the label of a dietary supplement must include:

  • A descriptive name of the product stating that it is a “supplement”
  • The name and place of business of the manufacturer, packer, or distributor
  • A complete list of ingredients
  • The net contents of the product

Tips to Keep in Mind Before Taking Supplements

  • Always consult your doctor about your options before choosing any supplement.
  • Take supplements as directed according to the label and your healthcare provider’s instructions.
  • Read the labeling, including ingredients, drug interactions, and percent daily value (% DV).
  • Be wary of extreme claims, such as “completely safe” or “works better than (insert prescription drug).”
  • Remember that the term “natural” doesn’t necessarily equal “safe.”
  • Keep supplements stored properly and away from children.
