Evidence-Based Supplements
The supplement industry markets aggressively to fertility patients. Here's what the peer-reviewed evidence actually supports:
Strong evidence
| Supplement | What It Does | Dosage (typical) | Evidence Level |
|---|---|---|---|
| Folate / Methylfolate | Neural tube defect prevention; may support egg quality | 800–1,000 mcg/day | Strong (universal recommendation) |
| Vitamin D | Associated with higher IVF success rates when levels are adequate (>30 ng/mL) | 2,000–4,000 IU/day (test first) | Moderate-strong |
| CoQ10 (Ubiquinol) | Supports mitochondrial function in eggs; may improve egg quality in women 35+ | 400–600 mg/day | Moderate (strongest data in older patients) |
| Omega-3 (DHA/EPA) | Anti-inflammatory; may support endometrial receptivity | 1,000–2,000 mg/day | Moderate |
Condition-specific
| Supplement | For Whom | Notes |
|---|---|---|
| DHEA | Women with diminished ovarian reserve (low AMH) | 25 mg 3x/day. Should be prescribed by your RE — not self-administered. Can take 6–8 weeks to show effects. |
| Myo-inositol | Women with PCOS | 2,000–4,000 mg/day. May improve egg quality and reduce OHSS risk in PCOS patients. |
| NAC (N-Acetyl Cysteine) | Women with PCOS or endometriosis | 600 mg 2x/day. Antioxidant that may support egg quality. |
For the male partner
| Supplement | What It Does | Dosage |
|---|---|---|
| CoQ10 | Supports sperm motility and reduces DNA fragmentation | 200–400 mg/day |
| Zinc | Supports sperm production and testosterone | 25–50 mg/day |
| L-Carnitine | Improves sperm motility | 1,000–2,000 mg/day |
| Vitamin C + E | Antioxidant protection for sperm DNA | 500mg C + 200 IU E daily |
| Folate | Reduces sperm DNA fragmentation | 400–800 mcg/day |
Don't self-prescribe DHEA
DHEA is a hormone — not a simple supplement. It should only be taken under the guidance of a reproductive endocrinologist who has reviewed your bloodwork (DHEA-S, testosterone levels). In women without diminished ovarian reserve, DHEA supplementation can be counterproductive.
Lifestyle Optimization
Diet
The Mediterranean diet has the strongest evidence base for fertility: high in vegetables, fruits, whole grains, fish, olive oil, and legumes. Limit processed foods, refined sugar, and trans fats. You don't need a specialty "fertility diet" — you need the diet that nutritionists have recommended for decades.
Exercise
Moderate exercise (30 minutes, 4–5 times per week) is associated with better IVF outcomes. Walking, swimming, cycling, and yoga are all appropriate. Avoid extreme endurance training or heavy weightlifting during stimulation — but staying active up to and during your IVF cycle is beneficial, not harmful.
Alcohol and caffeine
Eliminate or substantially reduce alcohol during the 3-month prep window and during treatment. Caffeine: limit to 200 mg/day (one moderate coffee). Neither is a fertility death sentence in small amounts, but both are easy to control.
Sleep
7–8 hours per night. Melatonin is both a sleep hormone and an antioxidant that may support egg quality — some evidence supports 3 mg nightly during the prep phase. Discuss with your doctor.
Stress management
Chronic stress elevates cortisol, which may interfere with reproductive hormone signaling. Evidence-based approaches: regular exercise, mindfulness meditation, therapy, and — genuinely — treating your IVF trip to Colombia as an opportunity for rest and reset rather than a source of additional anxiety.
Timeline: 3-Month Prep Checklist
| When | Action |
|---|---|
| Month 1 | Start supplements (folate, CoQ10, vitamin D, omega-3). Get baseline bloodwork. Begin diet and exercise adjustments. |
| Month 2 | Continue supplements. Reduce alcohol to zero. Schedule virtual consultation with clinic abroad. Review and adjust based on bloodwork results. |
| Month 3 | Continue all supplements. Finalize travel plans. Begin mental preparation. Confirm medication logistics with clinic. |
| Month 4 | Travel for treatment. Continue supplements through stimulation (ask your RE about stopping specific ones pre-retrieval). |
Sperm takes 74 days to mature
The male partner's supplement and lifestyle changes need a full 2.5-month lead time to affect sperm quality. Starting together at the 3-month mark ensures both partners are optimized when the cycle begins.
