Low libido and energy can stem from various factors, including stress, hormonal imbalances, or nutrient deficiencies. After blood tests to check hormone levels (like testosterone) and thyroid function, a doctor might suggest specific treatments. If a deficiency is found, supplements like Vitamin D, Zinc, or Coenzyme Q10 can support energy levels. Herbs like Ashwagandha or Ginseng are sometimes used to manage stress and support vitality. If clinically indicated, hormone replacement therapies might be considered. Please consult a healthcare professional to identify the root cause before starting any new medication or supplement, as tailored treatment is safest and most effective.
