Supplementation for Women Cyclists

The nutrition and supplementation industries are HUGE. As of 2023, the global dietary supplements market was valued at around $160 billion, and it’s got an entire advertising apparatus attached to it telling you to take this, take that, take everything… you could find yourself popping dozens of pills and spending hundreds every month on some often erroneous or even outright damaging stuff.

The trouble is that there is a good grain of truth to a lot of supplementation. There are some supplements that can really change your life – that can truly help you to live your best life and cycle your best ride, time after time. Unpicking these from the snake oil and, often from some of the more dangerous (and hardly regulated) elements of the industry’s output is tough.

Supplements

It gets even harder when you realise that most of the industry and the (often poor quality) research it bases it claims on are male focussed. Women, of course, have unique nutritional needs that can affect the type of supplements they should take. Hormonal fluctuations, bone health, and recovery requirements differ from those of men, meaning that women need to be more selective about their supplementation choices.

It’s dizzying. Happily, though, the list of supplements you should take is quite short, as is the list of supplements you should almost always avoid. So short that we have managed to squeeze it all into one blog post that should keep you right for years to come.

(Please note however, that no blog post can replace proper healthcare advice. If in doubt, consult with your healthcare provider to determine what your body needs.)

Our recommendations? It’s quite a short list – a handful of supplements (only seven, actually) that should pretty much cover everything that even the most balanced, healthiest diet might miss out...

  • IRON

    Iron is one of the most important supplements for you to consider taking - and one of the most critical nutrients for female athletes, especially those who are menstruating. Iron deficiency is more common in women due to blood loss during menstruation, and this can lead to fatigue, reduced endurance, and slower recovery times.

    Iron helps the body to produce haemoglobin, a protein in red blood cells that transports oxygen to the muscles. Without enough iron, your muscles won’t receive the oxygen they need during a ride, leading to fatigue and a drop in performance. If you’re noticing symptoms like constant tiredness or heavy legs, it may be worth having your iron levels checked.

    Always consult a doctor before starting iron supplementation, as too much iron can lead to other health issues. They may alternatively find that you are slightly anaemic (iron deficient) and have a treatment plan to deal with it.

  • CALCIUM AND VITAMIN D

    Bone health is particularly important for women, especially as they age. Calcium and Vitamin D work together to support strong bones, which is crucial for preventing injuries in cyclists. While calcium strengthens bones, Vitamin D enhances the body’s ability to absorb calcium.

    Women are at a higher risk of osteoporosis and stress fractures, making calcium and Vitamin D supplementation beneficial, especially if your diet is lacking in these nutrients. Women who don’t consume enough dairy or other calcium-rich foods may
    need to supplement to meet their daily needs. Vitamin D is also essential for
    immune function and muscle health, so if you live in a place with little sunlight, like the UK, it’s a smart addition to your supplement regimen.

  • PROTEIN POWDER (WHEY/PLANT-BASED)

    While protein is often associated with building muscle, it also plays a vital role in recovery. Many of us don’t consume enough protein in our regular diets, which can hinder muscle repair and leave you feeling sore after rides. Protein powder is a convenient way to ensure you’re getting enough to help your muscles recover, especially after long or intense rides.

    Whey protein is a popular option, but plant-based alternatives like pea or hemp protein are just as effective for those who prefer not to consume dairy. In fact, if you want a complete protein source (one that contains all 21 amino acids) a mix of 20:80 pea: soya protein will work well.

    The key is to consume protein post-ride, ideally within 30 minutes to an hour, to give your muscles the amino acids they need to repair and rebuild.

  • OMEGA 3 FATTY ACIDS

    Omega-3s are well-known for their anti-inflammatory properties, making them particularly useful for recovery after a tough ride. In addition to reducing inflammation, omega-3s support heart health and may help with hormonal balance, making them
    an excellent choice.

    Omega-3s are typically found in fish oil supplements, but there are plant-based alternatives like flaxseed oil or algae-based omega-3s for those following a vegetarian or vegan diet. Taking these daily can help with joint health, reduce muscle soreness, and improve cognitive function, all of which contribute to better
    overall performance on the bike.

  • ELECTROLYTES

    Hydration is key for athletes. However, you can drink as much water as you like and may still never fully rehydrate after a tough ride. You also need electrolytes, which help to maintain the body’s fluid balance. Women may experience more fluctuations in fluid levels during their menstrual cycle, which makes proper hydration even more essential.

    Electrolyte supplements can help to prevent dehydration, muscle cramps, and fatigue, especially during long rides and/or hot weather conditions. Look for supplements that contain sodium, potassium, magnesium, and calcium to keep your body in balance. Consider adding to your post-workout shake or drinking it on the move during your ride.

  • MAGNESIUM

    Magnesium is often overlooked but is vital for women looking to live an active, athletic life. It plays a key role in muscle function, helping to prevent cramps and muscle fatigue. Many women are prone to magnesium deficiency, which can lead to poor recovery (and even menstrual cramps!)

    Taking magnesium can help with muscle relaxation, improve sleep quality, and support energy production. It’s particularly beneficial during the menstrual cycle when magnesium levels can drop, leading to increased symptoms of PMS. Consider taking magnesium in the evening to aid with sleep and muscle recovery… and watch as your athleticism genuinely blossoms.

  • CREATINE

    Creatine is often associated with strength athletes, but it can be equally beneficial for endurance athletes like cyclists. It works by replenishing the body’s ATP (adenosine triphosphate) stores, which provide the energy needed for short bursts of high-intensity effort, such as sprinting or climbing.

    For female cyclists, creatine can enhance the ability to generate power during those crucial moments of a ride, helping with uphill pushes or intense final sprints. It’s typically taken daily, and the benefits accumulate over time, making it particularly useful during
    high-intensity training phases.

    Additionally, creatine can support lean muscle mass and improve recovery, allowing you to maintain strength and stamina throughout your training cycles.

Supplements to Approach with Caution or Avoid Altogether?

So, we know what we should consider taking. Honestly, stick to these seven and you’ll be fine. However, there are a few culprits worth highlighting - supplements that might otherwise be tempting.

  • 1. Fat Burners

    Fat burners are often marketed towards women for weight loss, but they can contain harmful stimulants that may lead to dehydration, heart palpitations, and hormonal imbalances. While the idea of quickly shedding weight might sound appealing, these supplements can do more harm than good, particularly for women who are trying to balance their hormones.

     

  • 2. High-Dose Multivitamins

    Multivitamins are often seen as a catch-all solution, but women’s supplement needs are more specific. High doses of certain vitamins, particularly A, D, and E, can cause toxicity or nutrient imbalances if taken unnecessarily. It’s better to focus on individual supplements tailored to your specific deficiencies rather than relying on an all-in-one solution.

  • 3. Pre-Workout Supplements

    Many pre-workout supplements contain high levels of stimulants like caffeine and beta-alanine, which can cause jitteriness and disrupt sleep patterns. For women, excessive caffeine can also disrupt hormonal balance, particularly during menstruation or menopause. If you need an energy boost before a ride, opt for a natural source like a small coffee or green tea, rather than a pre-workout formula with questionable ingredients.

  • 4. Testosterone Boosters

    Testosterone boosters are marketed to both men and women, but women should be particularly cautious. These supplements can disrupt your natural hormone levels and may interfere with your menstrual cycle or fertility. Avoid testosterone boosters unless specifically prescribed by a healthcare provider for medical reasons.

How to Choose the Right Supplement

Our advice? Choose anything from our first list and you can effectively ignore anything else, unless it comes recommended from a reputable source… even then, it’s important to focus on those that are backed by science and specific to your needs.

Look for third-party tested products certified by organizations like NSF or Informed-Sport - guaranteeing that supplements are free from harmful ingredients.

Supplements should never be a one-size-fits-all solution, especially for women whose needs may change during different life stages, such as menstruation, pregnancy, or menopause. Consulting with your healthcare provider regularly ensures that your supplement plan evolves alongside your body’s needs.
