I get adverse reaction to foods like dairy, nuts, and canola oil can only take small amounts of fish oil, any alternative food sources of omega ?

Many alternatives: Flax oil, hemp seed oil and chia seeds are excellent sources of essential omega 3 and 6 fatty acids. However, many people do not efficiently convert the Alpha linolenic acid found in vegetable foods into dha, an essential omega 3 which is found in fish oil. Products like omegazen provide dha derived from algae so it might be wise to supplement with that or a similar product.

Omega-3 alternatives: Flaxseed!!!!! Basil Soybean Brussel sprouts Cauliflower Tofu Shrimp Winter squash
