Hubby and I did a 2 week detox with bentonite clay and psyllium (google perfect 7 capsules) to reduce our levels of heavy metals, pesticides etc, at least a month before conception. We were also both taking the In-Liven probiotic & superfood supplement by MiEssence. We also tried as best as we could to avoid alcohol, coffee and any other drugs/medications that may adversely affect the health of sperm & egg.
