I always add a tablespoon of flax oil to my Grow! shake before bed and take 2g worth of fishoil capsules.
From time to time I add 1/8 cup full fat yogurt to my shake too. It increases the creaminess of the shake, aids digestion, and adds some saturated fat for improved T. I keep it limited to 1/8 cup to keep the carbs low because yogurt has a relatively high insulin index. I try to keep total carbs at <10g for P+F meals.
