The fertility podcast recommended various supplements taken once or twice per day, such as L Carnitine (supplemented w/garlic), CoQ10, & Shilajit (for men specifically). Is there any negative consequence of intermixing the intake of L Carnitine+garlic (1000 mg & 600 mg respectively) and CoQ10 (200 mg) every other day (for my wife and I), and taking the shilajit (at 200 mg) once per day (me only) instead of twice per day? My primary objective is to limit our body's dependency on these supplements for when we ultimately have successful insemination, and reduce potential for any toxicity levels, while still benefitting from their reproductive benefits. My wife raised a reasonable counterpoint that such a regimen might confuse her body at a time she is trying to maintain homeostasis for successful insemination. Thoughts?

has discussed the interplay between supplements like L-carnitine, CoQ10, shilajit, and fertility. Here are his insights and advice relevant to your concerns:

  1. Combination of L Carnitine and Garlic: Oral L-carnitine increases TMAO levels, which can stiffen arteries. To counter this, 600 mg of garlic (allicin) per day can be taken to offset TMAO's effects 1 2.

  2. Dosage and Frequency: The general recommendation for L-carnitine is 1-3 grams per day for 30 days before conception attempts. It's vital for sperm motility and egg health 1. CoQ10 dosage ranges from 100 to 400 mg per day and should be taken with a meal containing fats to enhance absorption 3.

    Improving Fertility

    Andrew explains how L-carnitine and Coenzyme Q10 can improve egg and sperm quality, and suggests taking 1 to 3 grams of L-carnitine per day and 600 milligrams of garlic extract to offset any increase in TMAO levels. He also mentions that coenzyme Q10 levels in the blood should be between 0.5 and 2.5.

  3. Effects of Supplements Across Menstrual Cycle: Women's hormonal cycles can cause varying reactions to supplements. Some women benefit from adjusting dosages of supplements like shilajit, depending on their menstrual phase. Tight control over dosage and individual ingredients is crucial to avoid negative effects 4.

  4. Shilajit's Use: Shilajit, enriched with fulvic acid, impacts testosterone and fertility positively, but its use and dosage should be monitored carefully, and consulting a physician is advised 2.

: also emphasizes combining L-carnitine with a multivitamin and CoQ10 for enhancing reproductive health, especially in males 5. This "sperm enhancement protocol" can be beneficial, but individual adjustments may be necessary for females, particularly those with endometriosis, due to their unique inflammatory environment 5.

Key Considerations

  • Dependency and Toxicity: Using these supplements intermittently, as you suggested, might help reduce dependency and potential toxicity while still offering reproductive benefits.
  • Consistency and Homeostasis: For your wife, maintaining a consistent supplement schedule might be more beneficial to avoid hormonal fluctuations and maintain homeostasis. Consulting with a healthcare provider to tailor the regimen to her cycle may prove advantageous.

Ultimately, adapting the supplement regimen based on individual responses and consultation with a healthcare provider is the best approach.

Understanding Fertility

  • Reproductive Anatomy: Detailed explanation of male and female reproductive systems, including the brain, pituitary, gonads (testes and ovaries), and their roles in fertility 1.
  • Fertility Testing:
    • Women should measure their antral follicle count and AMH levels.
    • Men should have a sperm analysis. Early testing provides useful reference points for the future 2.

Interventions for Optimizing Fertility

  • Supplements and Nutrition:
    • Supplements like L-carnitine, CoQ10, and shilajit can enhance reproductive health.
    • The importance of high-quality, single-ingredient supplements to maximize biological effectiveness 3.

      Reproductive Health

      Andrew discusses the male and female reproductive axis and how interventions such as exercise, L-carnitine, and stress reduction can increase fertility and optimize egg and sperm health. He emphasizes that optimizing fertility is also important for overall body and brain health.

  • Lifestyle Adjustments:
    • Exercise, proper sleep, and stress reduction significantly impact fertility.
    • Behavioral tools, such as reducing alcohol intake and addressing specific deficiencies 4.

Combined Health Benefits

  • Vitality and Longevity: Strategies to boost fertility often overlap with those enhancing overall vitality and longevity. These include better hormone regulation, reduced inflammation, and improved overall metabolic health 4.
  • Hormone Health: Regular hormone analysis (testosterone, estrogen, progesterone) is recommended to monitor changes and optimize overall health. This analysis helps track shifts due to age or lifestyle changes 5.

Additional Insights

  • Sex Selection in IVF: IVF procedures can select for biological sex by sorting sperm samples, though this is often secondary to ensuring chromosomal health 6.
  • Male Fertility Issues: One in five couples with fertility issues face challenges due to sperm quality rather than egg quality, stressing the need for comprehensive testing for both partners 2.
  • Importance of Early Testing: Early fertility testing, even in one's twenties, provides critical information and comparison points for later stages of life, helping to identify and address potential fertility issues early on 5.

Huberman emphasizes that these fertility-boosting measures also contribute to improved overall physical and mental health, making them beneficial even for those not looking to conceive immediately.
