Your Dr. knows your condition best and can give better advice. Do check with your Dr

supplements are only needed if you have a deficiency otherwise they can be toxic or useless. get a blood test first.

It's best to consume natural sources of protein & omega 3 than consume supplements. Prefer a healthy balanced diet eating every 2-2.5 hours.
If you are a vegetarian, consume lots of dals, pulses, dairy products, dry fruits, green leafy vegetables, fruits, cereals like oats, jowar & naachni. Legumes - lentils, peas, beans, chickpeas, soybeans & peanuts.
If you are a non vegetarian, you could add eggs and fish to the above list. Rich source of omega 3 in particular is walnuts, soybeans, eggs, cauliflower, canola oil, spinach.

Also as suggested above, before you take any supplements, take your doctors advice & get your self checked for deficiencies

Quick tip - Natural is best!
