We recently added hemp seeds to our diet - we just add them into our favorite recipes. We had been using chia seeds, but she says the latest research shows hemp has an edge over chia.
We're big, BIG fans of black seed oil - we use this for EVERYTHING. I use it as a daily skin moisturizer on my face, we take it internally for immune building, etc. It has SO many health benefits I can't even remember them all. (but I know our hair grows like crazy since we started taking it regularly, lol)
