Breastfeeding on demand (day and night) for a year is leaving my body depleted, and my immune system was shot since months. The same day of taking this product i noticed improved health (and i normally take zinc and mega vitamin C). And within 24 hours much better. My child also seems to have lowered immune system compared to when new born, nothing out of the ordinary, apparently this is normal (??), i hope this product goes through the milk. I found there is a Noregean company "Immuno Medic" that makes Beta Glucan syrup for children from 1 years of age and up, with dosage of 30 mg. So apparently you could feed Beta Glucan to your baby at appropriate dosages. I will update if there are any adverse effects. For exhausted breastfeeding mothers i recommend: Fermented cod liver /butter oil blend, and L-glutathione also. Always do your research, and test take before committing. Update 07/13/2013 I discovered the reason i had been so depleted was because i was eating too much grains. As soon as i reduced these i started to feel much better. With my baby, i stopped taking milk products for a while (she had been slightly allergic to milk), and this seemed to help. However it is important to take dairy products right away because of the significant amounts calcium/phosphate that vegetables do NOT provide (yes even greens). I no longer recommend spinach because of its high oxalic acid content that will bind to the calcium in the digestive system. The beta glucan really helped. I ended up giving my baby 1/2 of the capsule, and she was fine with this
