Here’s what we believe about probiotics:
1) Efficacy really depends on which one you take. Most probiotic pills on shelves are substandard. There are a handful that contain prebiotic substrate and probiotic microbes together in a pill that are better. Even then, the number of strains are limited.
This is why we recommend probiotic foods instead which have way more strains of healthy microbes. Refrigerated pickled vegetables like kimchi, natto, sauerkraut etc. (shelf stable ones have been sterilized with no live microbes). Artisanal and/or imported cheeses and yogurts made from sheep or goat milk (less likely to contain hormones and toxins).
2) Probiotics are definitely good after antibiotics but it depends what kind. Stick to probiotic-rich foods and the highest quality probiotics.
3) Prebiotics are as important, if not more, than probiotics. Your gut already has a thriving microbiome. Is dumping loads and loads more microbes in it through a probiotic pill really the best thing you can do for them? No. The best thing you can do is create an environment and provide them with the foods that help them achieve a healthy balance. That's what prebiotics are: food for your microbiome. Of these, polyphenols from fruits, vegetables and superplants are the most effective.
4) Amongst all the highest polyphenol foods, tea is the easiest one to consume in quantity daily. Drinking 3-7 cups of tea a day is hugely beneficial to gut health (something about 1/4 - 2/3 of the world's population has been doing with great results for hundreds of years). If you drink this much tea, make sure it’s screened for toxins like heavy metals, pesticides and toxic mold like Pique. These toxins can make your gut health worse even if the tea is beneficial.
5) Adding spices to food is another great way to get polyphenols, sumac and oregano are both high in polyphenols amongst many others.
