Bottom line up front: While no diet or supplement can guarantee IVF success, a growing body of research supports specific nutritional and lifestyle strategies that may improve egg quality, sperm quality, and overall fertility outcomes. The best part: many of these changes are easy to implement during your time in Colombia, where fresh, affordable produce and an active outdoor lifestyle are built into daily life.
The Mediterranean Diet Connection
Multiple studies have found an association between adherence to a Mediterranean-style diet and improved IVF outcomes, including higher rates of clinical pregnancy and live birth. The Mediterranean diet emphasizes vegetables, fruits, whole grains, legumes, nuts, olive oil, fish, and moderate dairy while minimizing processed foods, red meat, refined sugars, and trans fats.
Colombia's food culture aligns naturally with many of these principles. Fresh tropical fruits (mango, papaya, guanabana, lulo, maracuyá) are abundant and inexpensive. Grilled fish and chicken are staples. Avocados cost a fraction of US prices. Restaurants serve fresh-prepared meals with vegetables, beans, and rice. Eating well during your IVF cycle in Colombia is easy and affordable.
Start Early
Egg development takes approximately three months from initial recruitment to ovulation. This means dietary and lifestyle changes implemented two to three months before your IVF cycle have the greatest impact on egg quality. If possible, begin optimizing your nutrition before you travel.
Supplements With Research Support
The following supplements have some evidence supporting their use before and during IVF. Always discuss supplements with your fertility specialist before starting them, as individual circumstances vary.
| Supplement | Proposed Benefit | Typical Dose | Evidence Level |
|---|---|---|---|
| CoQ10 (Ubiquinol) | May improve mitochondrial function in eggs, particularly for patients over 35 | 400–600 mg daily | Moderate — promising studies in older patients |
| Vitamin D | Deficiency associated with lower IVF success rates; maintaining adequate levels may improve outcomes | 1,000–4,000 IU daily (based on blood levels) | Moderate — consistent association in observational studies |
| DHEA | May improve ovarian response in diminished ovarian reserve patients | 75 mg daily (25mg x3) | Moderate — some clinic-specific protocols include this |
| Folate / Methylfolate | Essential for neural tube development; important to begin before conception | 400–800 mcg daily | Strong — universally recommended |
| Omega-3 (DHA/EPA) | May improve egg quality and uterine blood flow | 1,000–2,000 mg daily | Moderate — supportive evidence from several studies |
| Vitamin E | Antioxidant that may improve endometrial thickness | 200–400 IU daily | Limited — some supportive evidence |
Lifestyle Factors
Exercise: Moderate exercise is beneficial — walking, swimming, yoga, light cycling. Avoid high-intensity exercise during stimulation as your ovaries will be enlarged. MedellÃn's year-round spring weather is ideal for daily walks.
Sleep: Aim for seven to nine hours per night. Disrupted sleep has been associated with hormonal imbalances that may affect fertility. The quiet neighborhoods of El Poblado and Laureles make restful sleep easy.
Alcohol: Most fertility specialists recommend eliminating alcohol entirely during your IVF cycle and ideally for one to three months before. Research links alcohol consumption to reduced IVF success rates.
Caffeine: Moderate caffeine (one to two cups of coffee daily) is generally considered acceptable. Colombia happens to produce some of the world's best coffee — you do not have to give it up entirely, but keep it moderate.
Stress management: While research has not proven that stress directly reduces IVF success, managing stress improves your overall experience and wellbeing during treatment. Many patients find the change of environment that comes with traveling to Colombia for treatment naturally reduces their stress levels.
