Stacking supplements gets you nowhere. If anything, supplement blends are becoming more targeted, niche-oriented, and supercharged. This makes it harder to find the right mix for you, especially those that don’t have drug interactions. Luckily, these supplement packs from experts in South Africa make a great guide for women.
Meet the experts: Sikhosande Kula and Nicolene Schoeman are pharmacists based in South Africa.
Stacking supplements is a smart way to get your vitamins and minerals, taking into account your needs, diet, activity levels and overall requirements. Given the way stress and other factors can deplete your body’s nutrients, “supplements can be a safe and effective way to fill these gaps – especially when tailored to individual needs and not taken blindly,” explains pharmacist Sikhosande Kula. But, warns Nicolene Schoeman, a pharmacist: “They are there to fill gaps, not to be a miracle solution or to reverse the effects of poor diet, lack of exercise or chronic stress.”
Why it works
However, “supplements can be incredibly useful in certain situations,” says Schoeman. “For example, if you’re training hard for an event, following a restrictive diet for health or ethical reasons, or dealing with allergies that limit your food choices. During my busy season, when meal prep falls behind, I sometimes turn to targeted supplements to make sure my bases are covered.”
Kula says supplements can also help address multiple aspects of health at once. For example, he explains that combining magnesium with B vitamins is an excellent way to increase energy and support the nervous system. This is because some vitamins work synergistically: vitamin D supports calcium absorption; Omega-3 fatty acids improve the effects of antioxidants. Additionally, Kula says, many stacks are used to meet specific requirements, such as PMOS.

Expert-recommended supplements for South African women
“As a clinical pharmacist and mother who tries to live an active, balanced lifestyle, my golden rule when it comes to supplements is simple: They should complement, not replace, a healthy diet and lifestyle,” says Schoeman.
Hormonal health supplements
These nutritional supplements help control metabolic functions and hormonal harmony.
Inositol (Myo and D-Chiro variants)
Supports insulin sensitivity and ovulatory function
Modern clinical guidelines support the use of a 40:1 Myo-Inositol to D-Chiro-Inositol ratio (typically 4,000 mg MI to 100 mg DCI daily) to improve overall ovarian function, reduce hyperandrogenism (excess male hormones), and restore consistent ovulation.
Omega-3
Reduces inflammation and supports hormonal balance
A meta-analysis in the Journal of Translational Medicine found that omega-3 supplementation specifically lowered total triglycerides and LDL cholesterol, making it an excellent defense against the metabolic and cardiovascular risks associated with PCOS.
Vitamin D3
Hormone health
“Vitamin D is often found in small amounts in PCOS cases and influences insulin and hormone regulation,” says Kula. A rigorous, double-blind, prospective, randomized, controlled trial presented in BMC Endocrine Disorders examined the effects of long-term vitamin D3 replenishment in women with PCOS. The study found that correcting vitamin D deficiency significantly improved ovarian morphology (reduced cyst occurrence), significantly increased ovulation rates, and regulated the length of the menstrual cycle.
magnesium
Supports blood sugar balance
Clinical evidence in Frontiers in Endocrinology suggests that while magnesium alone provides modest benefits, concurrent supplementation (combining magnesium with synergistic nutrients such as vitamin D or vitamin E) shows highly significant, synergistic improvements in reducing fasting blood insulin and HOMA-IR levels.
Some vitamins work synergistically: Vitamin D supports calcium absorption; Omega-3 fatty acids improve the effects of antioxidants.

Best Supplements for Fertility in Your 30s
As an active woman committed to hormonal health, pharmacists agree that women in South Africa would benefit from this.
Prenatal multivitamins (if pregnant)
Folic acid is essential for fetal development during pregnancy.
Folate (vitamin B9) is generally considered the most important nutrient before conception. Folic acid must be present in high levels in the body during the first 28 days of pregnancy – often before a woman even knows she is pregnant – to ensure that the baby’s neural tube closes properly and prevent serious defects such as spina bifida.
Omega-3 (DHA-focused)
Supports fetal brain and eye development
Omega-3 fatty acids serve as building blocks for prostaglandins and hormones that regulate ovulation and regular menstrual cycles. They also help with pregnancy efforts: severe inflammation can interfere with regular ovulation and reduce egg quality. Omega-3 fatty acids reduce inflammation, which is beneficial for conditions such as endometriosis or PMOS.
iron
Supports energy and blood volume changes.
Once you are pregnant, your blood volume increases by about 50%. Entering pregnancy with depleted iron stores (iron deficiency or anemia) dramatically increases your risk of fatigue, miscarriage, and low birth weight.
magnesium
Reduces cramps and supports sleep
Magnesium is a vital mineral that controls over 300 biochemical reactions and acts as a natural nervous system relaxant and metabolic balancer. Magnesium helps maintain healthy progesterone levels by managing stress. When you’re chronically stressed, your body prefers to make cortisol (“the stress hormone”) rather than progesterone, which can shorten your luteal phase and make implantation more difficult. Magnesium breaks this cycle.
Supplement stack for mood support
People suffering from depression or anxiety may benefit from these supplements. Kula recommends these, which can be used to enhance the effects of antidepressants but also work alone.
Omega-3 fatty acids (EPA/DHA)
Mood and cognitive support
In 2016, Australian researchers found that omega-3 fatty acids may help increase the effectiveness of antidepressants in people with clinical depression. Omegas play a role in brain health, and science shows that people with depression often have lower levels – making supplementation particularly useful.
Magnesium glycinate
Supports relaxation and balance of the nervous system
Magnesium is an important sleep aid and is particularly important for balancing the nervous system and maintaining calm. When you are under chronic emotional, psychological or physical stress, your body quickly empties its magnesium stores through urine. This leads to a biological catch: low magnesium levels make you much more susceptible to stress and depression, while high stress burns off the very mineral you need to stay calm.
B complex
Supports the production of neurotransmitters
Studies have shown that B vitamins are useful as an adjunct to depression treatment and may have positive effects on reducing the intensity of depression, anxiety and pain. They speed up the response to antidepressants, improve cognitive speed, and can reduce anxiety and PMS-related mood swings.
Vitamin D3
Mood regulation, immune support
A 2022 study in the Journal of Multidisciplinary Health found that vitamin D improved depression symptoms, especially at higher doses. These require medical clarification, as fat-soluble vitamins can have toxic effects in excessive doses.
Resources to skip: Natural remedies are not risk-free. For example, St. John’s wort and 5-HTP may interact dangerously with prescription antidepressants (risk of serotonin syndrome) or reduce the effectiveness of contraception. Skip these – and always consult your doctor before taking any new supplement.

Best Supplements for Burnout and Busy Women
“My go-to package for busy, tired, hormonal, and burnt-out women is all about supporting energy, mood, hormones, and recovery,” explains Schoeman. “Of course, the exact mix depends on what’s really behind your fatigue, but here’s a solid foundation that I often recommend.” Of course, burnout needs to be managed through lifestyle changes, workload, and setting boundaries—but these are helpful additions.
magnesium
Promotes peaceful and better sleep
Magnesium relieves physical anxiety, improves sleep quality and prevents neuronal burnout. It prevents cortisol (“the stress hormone”) from entering the brain and prevents the overproduction of adrenaline, directly protecting your nervous system from burnout.
B vitamin complex
Helps balance mood and hormones – important for nerve function
“Important for mood, immune system health and hormonal balance – but around 1 billion people worldwide suffer from a deficiency,” says Schoeman. “I think most women should at least check their values.”
Omega-3
Brain booster and heart health
Anti-inflammatory and important for brain, heart and hormone health. If you don’t eat a lot of fatty fish, a high-quality omega-3 can help fill the gap. Omega-3 fatty acids actively combat the physiological toll that prolonged, chronic stress causes on your brain and hormonal system.
Protein powder
Increases satiety and muscle repair
“It helps meet your daily protein goals, supports muscle repair, and keeps you fuller for longer—which is important when you’re juggling meals between meetings, kids, and training,” says Schoeman.
