Why Men’s And Women’s Bodies Need Different Care

When it comes to health and wellness, there isn’t an all-in-one solution that suits everybody. Both men’s and women’s bodies function differently at a biological level. This can be from hormones and metabolism to bone and heart health. It’s important that we understand these distinctions, so we’re able to give our bodies the correct vitamins and nutrition it needs.

Hormonal Regulation

Women

Oestrogen is the centre of women’s hormone health, but its levels do fluctuate throughout a woman’s lifespan such as the menstrual cycle, pregnancy, and menopause[1]. These hormonal shifts can influence and change everything from mood and energy to metabolism. Hormones can also impact how the body uses essential nutrients such as iron, calcium, and B vitamins, which means women’s dietary needs can change from month to month or year to year.

Men

Men’s hormones tend to be more stable. Testosterone is the main focus on male hormone health[2], and can influence muscle growth, metabolism, and red blood cell production. While testosterone levels do decline with age, the change is gradual, leading to a slower shift in overall health needs. While the needs may be less obvious, it’s still essential that the male body gets essential nutrients such as vitamin D, zinc and magnesium.

Muscle Mass & Body Composition

Men

Men generally have more lean muscle mass, which contributes to a higher resting metabolic rate. This means they often need more energy and protein [3]to maintain muscle and support recovery, especially if they’re active or strength training regularly. The best sources of protein are naturally through food, but nutrition such as whey protein powder can help. Additionally, with energy, supplements like creatine monohydrate, zinc and magnesium can help elevate energy levels.

Women

Women naturally have a higher percentage of body fat and less muscle mass than men[4]. This can affect metabolism, meaning women typically burn fewer calories at rest. As a result, their bodies use nutrients differently, prioritising fat storage and energy balance. The best way to maintain these levels are B vitamins, omega-3 and probiotics.

Bone Health

Women

After menopause, declining oestrogen levels accelerate bone loss. This makes women more susceptible to osteoporosis and fractures[5]. Adequate calcium, vitamin D, and weight-bearing exercise are essential for maintaining bone strength throughout life.

Men

Men do also experience bone loss, but usually more gradually and later in life. Lower testosterone levels can contribute to weaker bones[6], so maintaining hormonal balance, staying active, and getting enough nutrients such as calcium, vitamin D and vitamin K2 remain important.

Iron & Blood Health

Men

Men generally have higher iron stores, but too much iron can actually raise cardiovascular risks[7]. For men, moderation and awareness around supplements are very important - especially if their diet already provides plenty of iron.

Women

Because of menstruation, women lose blood regularly, which increases the risk of iron deficiency or anemia[8]. Eating iron rich foods like red meat, lentils and greens alongside vitamin C for better absorption - all can help maintain healthy levels.

Reproductive Health

Women

Women experience changing nutritional needs throughout life. Examples of this are during menstruation, pregnancy, breastfeeding, and menopause. All of these stages all require tailored care to support hormonal balance and reproductive health. If nutrition is not enough to support the full needs, supplements can help with this such as folate (vitamin B9), coenzyme and evening primrose oil.

Men

For men, reproductive health largely centers on sperm quality and testosterone balance. Nutrients and supplements such as zinc, selenium, and omega-3 fatty acids can help support healthy sperm production and prostate function[9]. Strength training and moderate cardio can also support testosterone production - however, it’s important to understand that excessive endurance exercise can lower testosterone if overdone.

Understanding men’s and women’s bodies function differently at biological, hormonal, and physiological levels is important. By recognising and addressing each of our specific health needs, we can promote long-term vitality, hormonal balance, and overall quality of life.
