  • Amazing Lactation Support - Really Works!
Style: Unflavored (15 oz)
This Mommy Knows Best Brewer's Yeast has been a lifesaver during my breastfeeding journey! After struggling with low milk supply in my first few weeks postpartum, my lactation consultant recommended adding brewer's yeast to my routine, and this product delivered exactly what I needed. Within just a few days of adding a tablespoon to my morning smoothie, I noticed a significant increase in my milk production. What had been barely enough for my baby became a comfortable, steady supply that gave me so much peace of mind as a new mom. The powder mixes easily into smoothies, oatmeal, or even baked goods without creating a gritty texture. The taste is surprisingly mild - slightly nutty but not unpleasant at all. Being gluten-free was important for me since I'm sensitive to gluten, and it's reassuring to know I'm not compromising my dietary needs. The 15 oz container lasts quite a while with daily use, making it excellent value. The packaging keeps the powder fresh, and the wide opening makes it easy to scoop without mess. Beyond milk supply, I've noticed my energy levels are more stable throughout the day, which is crucial when dealing with sleep deprivation and the demands of caring for a newborn. For any breastfeeding mom struggling with supply issues, this is absolutely worth trying. Natural, effective, and gentle on the system. I'm already planning to reorder before I run out! ... show more

  • A Mild-Tasting Miracle for Breastfeeding Mums
Style: Unflavored (15 oz)
The Overview: After experiencing a stressful event that affected my milk supply, I turned to Brewer's Yeast Powder for Lactation Support, which is marketed as mild-tasting and debittered. Here's how it worked for me: The Good: Effective Milk Supply Increase: Within just a few days of adding a spoonful to my morning decaf coffee, I noticed a significant improvement in my milk supply. It worked perfectly for my needs. Nutritional Benefits: I had blood work done which showed exceptionally high levels of Vitamin B, likely thanks to this supplement. This was an unexpected but welcome bonus. Taste and Texture: While there is a slight flavor and texture change to my coffee, it wasn't bothersome enough to detract from its benefits. The debittered version truly makes it more palatable. Longevity and Value: One container lasted me around 3-4 months with daily use, making it not only effective but also economical. I've reordered it due to its positive impact. The Not-So-Good: Slight Taste Alteration: If you're very sensitive to changes in taste, you might notice the yeast's influence on your beverage. However, I found it quite manageable. Overall: This Brewer's Yeast Powder has been a lifesaver for me in maintaining and boosting my milk supply post-stress. The mild taste, significant nutritional benefits, and long-lasting supply make it a go-to supplement for any breastfeeding mother looking to naturally support lactation. Pros: Quickly and effectively boosts milk supply Rich in Vitamin B, enhancing nutrition Mild taste and texture, easy to incorporate into daily routine Great value with a container lasting several months Cons: Minor taste change, though not significant for most Conclusion: If you're a breastfeeding mother looking for a natural way to support your milk supply, this Brewer's Yeast Powder is highly recommended.

  • Brewers Yeast for Milk Supply
Style: Unflavored (10 oz)
I was about two weeks postpartum when I started taking brewers yeast and it made such a difference for me. Before that, I was struggling to produce enough milk and starting to worry I wouldn’t be able to keep up. After adding brewers yeast into my routine, I noticed a real increase in my milk supply and it worked surprisingly fast. Brewers yeast is rich in B vitamins, protein, iron, and chromium. These nutrients help support energy and hormone balance, which are both so important for new moms. It’s often recommended as a natural galactagogue, something that promotes milk production, and it truly lived up to that reputation for me. Everyone’s body is different, but for me this supplement helped me feel more confident and less stressed about feeding my baby. It’s definitely something I’d recommend to other moms who are looking for a natural way to support their milk supply. ... show more

  • Not bad
Style: Unflavored (15 oz)
The product does have a faint taste that is strong. It has helped increase my milk. The only thing I dont like is that it is grainy. I wish it dissolved better.

  • GREAT!!!
Style: Chocolate Brewer's Yeast
I was feeling really nervous about my milk supply since I noticed it’s been going down since I started working out. I bought brewer’s yeast per the recommendation of friends. Literally the first day taking this at night, I woke up engorged and pumped 6 oz in my MOTN pump, which is a LOT for me (I’m usually 2-2.5 oz a pump). The smell and texture leave much to be desired so I can’t say that it’s delicious. You can definitely smell and taste the yeast if you’re blending it into a smoothie. Maybe you’d have better luck making brownies/cookies in terms of not tasting it. I just drink my smoothie really fast to get it over with and get the results. Also, to forewarn you, it may make you quite gassy to be sure to check to see how your baby handles it also. ... show more

  • Yucky taste
Style: Unflavored (10 oz)
I’m not certain that I’ve noticed a dramatic impact on my milk from this. It’s definitely not flavorless, a concerted effort was made, but it absolutely has a very strong flavor. It does not dissolve in hot or cold liquids, and it will sit at the bottom of whatever you’re drinking and then you have to drink silt liquid to get it all once you’re down to the bottom of your cup. It mixes decently in smoothies, but you need to have a lot of strong fruit to mask the smell and taste. I tried the brand Kate Neutrals as well and again, I can’t vouch towards efficacy, but it doesn’t taste as bad. I do appreciate that it is all made in America, but I’m not sure if I will be buying this product again. ... show more
