Vitamin D
“Worldwide, an estimated 1 billion people have inadequate levels of vitamin D in their blood, and deficiencies can be found in all ethnicities and age groups […] Few foods are naturally rich in vitamin D, so the biggest dietary sources of vitamin D are fortified foods and vitamin supplements.”

Supplement: Look for over 2,000 IU minimum, up to 10,000 IU.
B Vitamins
Symptoms associated with B deficiency: brain fog, fatigue, thinning hair, back pain, infertility — just to name a few. Technically there are eight types of B’s, and we need all of them to work together to absorb into the body properly. B12 is found mainly in meat, but, low B12 levels are still common even for individuals that consume a lot of meat.

Supplement: The best way to know you’re getting enough of all B’s is to take a B-Complex, especially one high in B12.

Omega 3’s
Our brains require healthy fat to function. Not getting enough fat in our diets can genuinely cause symptoms of depression and anxiety. Both omega 3’s & 6’s are necessary, but we get plenty of omega 6’s in our every day meals. Too many omega 6’s can cause inflammation and other imbalances in our bodies. To balance this, it’s beneficial to know which foods are high in omega 3’s, but many choose to take a supplement to be safe.
Essential For: Supports healthy heart & brain function, plus healthy blood sugar and triglycerides.
Food: Chia seeds, hemp seeds, walnuts
Supplement: fish oil tablets are most common in stores, but if you’re plant-based, there are online shops that carry vegan omega 3s tablets.
