Do Workout Supplements Affect Birth Control?

It’s a common question asked by many women who are trying to stay fit and healthy: do workout supplements affect birth control? The answer is not entirely clear, but there are some things to keep in mind if you’re taking birth control and working out.


The relationship between birth control and supplementation has recently become a subject of increased research and interest. The importance of understanding the potential impact of supplement use on the efficacy of birth control is especially relevant in light of the increasing number of individuals who are choosing to supplement in an effort to obtain better physical fitness results. Studies have found that certain supplements, including some common workout supplements, may interfere with the effectiveness of oral contraceptives and other forms of contraception. It is important to be aware that certain brands, ingredients, and doses could affect one’s own contraceptive methods. This article will review current evidence regarding how popular workout supplements could potentially affect birth control pills and other forms of contraception.

How Birth Control Works

Birth control is an effective way to prevent pregnancy. Birth control works by preventing ovulation, fertilization, or implantation of a fertilized egg. Different methods of birth control achieve this in various ways, but all of them rely on hormones to prevent pregnancy. In this article, we will discuss how birth control works and how workout supplements may interact with it.

Hormonal Birth Control

Hormonal birth control works by introducing synthetic hormones into the body. These hormones prevent the ovaries from releasing eggs and also thicken cervical mucus to obstruct sperm, helping to prevent pregnancy. Different types of hormonal contraception work in slightly different ways but all provide a high level of protection when used according to instructions.

Different types of hormonal contraception are available — including the pill, implant, patch, ring, intrauterine device (IUD), and injection. Each type delivers varying amounts of the hormones progestin and estrogen into your body. It’s important to consider your personal health history before selecting a method since some methods are riskier than others for certain conditions or factors prior existing medical history.

Most health organizations agree that workout supplements do not interfere with or change the effectiveness or safety profile of hormonal birth control — including pills — when both are used as instructed by your doctor or other healthcare provider. It is still important to tell your healthcare provider about any medications you take regularly, including workout supplements, so they can evaluate their safety alongside your prescribed contraceptives if you choose to combine them.

Non-Hormonal Birth Control

Non-hormonal birth control pills, such as barrier methods and sterilization, work to prevent an egg from being fertilized or implantation in the uterus. Barrier methods work by blocking sperm from entering the uterus, while sterilization is a permanent means of preventing pregnancy. Common types of non-hormonal birth control include:

-Condoms: Condoms are available in different styles and are made from a variety of materials, including latex, polyurethane, and lambskin. They should always be used with water- or silicone-based lubricant to help prevent breakage.
-Diaphragm: A diaphragm is a shallow cup inserted into the vagina before sex and left in place for up to 24 hours afterward. It works as a form of birth control by covering the cervix and preventing sperm from entering. It’s important to note that it should not be left in for longer than 24 hours and should not be reused without first washing it thoroughly with warm water and soap.
-Contraceptive sponges: The contraceptive sponge is composed of synthetic foam placed deep inside the vagina before sexual intercourse; its main action is to cover the cervix blocking sperm access. It also contains spermicides which help kill sperm on contact; this product must be left inside for 6 hours after sex but can stay up to 24 hours if needed. Contraceptive sponges may also have some side effects including irritation or allergic reactions with repeated use in some users.
-Cervical caps: Cervical caps are similar to diaphragms but smaller; they fit over the cervix like a rubber hat does over a head, where they form a seal that prevents any sperm from passing through into the uterus for fertilization purposes. Cervical caps must remain inserted for 6–8 hours after sex but can stay up to 48 depending on your needs. They come in different sizes so you may need refitting after childbirth or significant weight gain/loss since they may not be as effective when they don’t fit correctly anymore.

Types of Workout Supplements

There are many types of workout supplements that can be beneficial for athletes and bodybuilders. Protein powders, creatine, and BCAAs are some of the most popular types of supplements. Each of these supplements have different effects on the body and can have different levels of effectiveness. In this article, we’ll be discussing the various types of workout supplements and how they could potentially impact your birth control.

Protein Supplements

Protein is a macronutrient and is essential to building muscle, maintaining a healthy body weight, and aiding in recovery after physical exertion. If you’re looking to boost your protein intake, there are many protein supplements available on the market today. Popular types of protein include whey, casein, soy, hemp, and egg white.

Whey Protein: A popular choice amongst athletes as it’s absorbed quickly by the body. Great for taking post-workout because it helps muscle development and recovery.
Casein Protein: This is a slow-absorbing type of protein that helps keep muscles nourished for longer periods of time.
Soy Protein: Soy is a vegan option that can be used by those who are unable to consume dairy products. It contains all nine essential amino acids necessary for muscle growth and maintenance.
Hemp Protein: Hemp is high in fiber for maintaining healthy digestion and fats for boosting energy levels. It also contains all nine essential amino acids needed to build muscle mass.
Egg White Protein: Egg whites are rich in protein with minimal fat content making them great pre or post-workout snack choices. The whites contain high amounts of BCAA’s (branched chain amino acids) which provide energy during workouts as well as promoting better absorption of nutrients into the bloodstream.

Pre-Workout Supplements

Pre-workout supplements are products designed to help support energy, concentration, and performance before workouts. These supplements often contain a blend of natural stimulants like caffeine, B vitamins, and amino acids, as well as added stimulants such as DMAA or Phenethylamine. The use of pre-workout supplements has been increasingly popular among exercise enthusiasts over the last several years.

When looking for a pre-workout supplement it is important to read the label carefully and understand exactly what is being suggested by the product. Many of these products contain ingredients with potential side effects which should be taken into account when using them in conjunction with any medications or birth control pills. Some ingredients in pre-workouts can interact negatively with birth control pills, negatively impacting their effectiveness. It is important to discuss this potential risk with your Doctor before beginning any supplement program.

Common pre-workout supplement ingredients include: Creatine Monohydrate; Beta Alanine; Citrulline Malate; Caffeine Anhydrous; HMB (β–Hydroxy β-Methylbutyrate); L‑Tyrosine; Rhodiola Rosea Extract; B‑Vitamins (Folic Acid & Vitamin B6); Taurine; Glucuronolactone; Startchild Bluegrass Extract (KannaEase); KSM-66 Ashwagandha Extract; Agmatine Sulfate and Niacinamide (Vitamin B3).

Creatine Supplements

Creatine supplementation is one of the most common and widespread forms of supplementation used in the fitness world. It is a dietary supplement derived from three amino acids – arginine, methionine, and glycine – that plays an important role in providing energy to your cells. When taken regularly, creatine can enhance muscle mass, strength and power output. Additionally, it has been linked to improved heart health by reducing blood pressure and cholesterol levels. Creatine supplements may also affect the effectiveness of certain birth control methods since they increase testosterone levels. It is advised to research further before combining this supplement with any form of contraception as safety varies greatly from person to person.

In terms of types of creatine supplements available on the market today, there are two main types: monohydrate and liquid forms. Monohydrate is considered the original form which has been around for over 20 years and provides approximately 5-10 grams per day; liquid forms generally come in powdered form usually containing 3-5 grams per scoop or per serving size package; other forms include nitrate or ester formulations which are more expensive but may be more easily absorbed into muscle cells depending upon individual needs and preferences. Lastly, more recent research suggests that adding beta-alanine to a creatine supplement routine may improve results even further although only time will tell if this holds true through clinical trials.

Potential Interactions

Since certain workout supplements may contain ingredients that can interact with certain medications, it is important to consider any potential interactions when taking both at the same time. This is especially true for women who are taking birth control pills. In this article, we will look at the potential interaction between workout supplements and birth control pills.

Hormonal Birth Control

Hormonal birth control typically contains a combination of an estrogen and a progestin, or it may contain only progestin. Hormonal birth control is commonly taken in the form of pills, a shot, a patch, or an implant. Hormones included in oral contraceptive pills work to prevent pregnancy by thickening the cervical mucus and thinning the lining of the uterus. The hormones can also inhibit ovulation by preventing eggs from being released from the ovaries during each menstrual cycle.

Because of their effect on hormones, workout supplements that contain herbal extracts and other ingredients such as caffeine can interfere with birth control’s effectiveness. For example, St. John’s wort is a common herbal supplement known to affect placental cells and synthetic hormones- including those found in hormonal birth control- which could reduce its efficacy. Similarly, certain supplements containing green tea extract which also contains caffeine may block certain receptors responsible for hormone production that could reduce the effectiveness of hormonal contraception when certain doses are exceeded. In addition, athletes using steroids may metabolize oral contraceptives much more quickly than non-athletes which can reduce its efficacy as well due to the higher levels of testosterone present in these individuals As such those taking hormonal contraception should be aware of potential supplement interactions with their medication when considering taking any workout supplements or diet aids for weight loss or performance enhancement purposes.

Non-Hormonal Birth Control

Non-hormonal birth control works by keeping sperm from joining with an egg. Non-hormonal birth control methods, such as intrauterine devices (IUDs), diaphragms, and vaginal rings, are designed to block sperm from reaching the egg. While these methods do not involve hormones and can be very effective in preventing pregnancy, they are not 100-percent foolproof and it’s important to take precautions in all scenarios.

It is important to note that most workout supplements do not directly interact with any type of non-hormonal birth control. However, certain over-the-counter medications or herbal remedies may interact negatively with any type of contraception you’re using. If you are taking a new workout supplement and have concerns about potential drug interactions with your birth control method, make sure to talk to your doctor about possible risks before starting the regimen.
It’s also important to note that depending on the ingredients in the supplement you’re taking, it could still potentially interfere with how well your contraception works. Supplements like zinc and calcium may interact with certain non-hormonal forms of birth control like copper IUDs and diaphragms; herbs like feverfew, chaste tree berry, black cohosh root extract, or wild yam root extract may create similar issues. Talk to your doctor if you have questions about how a specific supplement might affect your chosen contraceptive method.


In conclusion, it is important to consider any potential interactions between birth control and workout supplements before using both. In some cases, the combination of the two may increase pregnancy risk and put the user at a higher risk of side effects. It is best to consult with a healthcare professional before combining any supplement with hormonal contraceptives, including those contained in over-the-counter birth control supplies. Additionally, users should always read the labels carefully and follow directions on product labels when ingesting supplements. Taking preventive steps can reduce users’ risks and help ensure that they are safe while using both workout supplements and birth control.
