Plant oils for vitamin deficiency: what to choose and how to use them

The off-season is a time when the human body becomes especially vulnerable to negative external factors. A lack of fresh seasonal fruits and vegetables, along with insufficient sunlight that leads to vitamin D deficiency, increases the burden on the immune system. As a result, the body must expend more energy adapting to temperature fluctuations and atmospheric pressure changes.

In addition to drowsiness, constant fatigue, and apathy, vitamin deficiency (avitaminosis) can trigger flare-ups of chronic diseases and increase the frequency of flu and common colds. During spring, the body particularly needs vitamins, minerals, and essential micro- and macronutrients for the proper functioning of all organs.

A natural way to support immunity and boost overall vitality is through cold-pressed plant oils. These are natural products rich in nutrients that are extremely beneficial for health.

Best oils for vitamin deficiency and immune support

It’s difficult to say that one plant oil is universally better than another. However, when it comes to immune-boosting properties, the most valuable are: flaxseed oil (linseed oil) and black seed oil (black cumin oil / Nigella sativa oil).

Cold-pressed flaxseed oil is rich in alpha-linolenic acid (ALA), a type of omega-3 fatty acid, as well as lignans — plant compounds involved in lipid metabolism and immune regulation.

Key benefits of flaxseed oil are supports immune system function, helps the body respond faster to viruses and bacteria, contains zinc, known for its anti-inflammatory properties and rich in vitamin E, a powerful antioxidant that protects cells from free radicals.

Just 1 tablespoon of flaxseed oil daily provides the recommended intake of omega-3 and vitamin E for adults.

How to use: take it raw (on an empty stomach or with meals), add to salads, cereals, or side dishes (not heated).

Black cumin seed oil contains vitamins A, E, D, and B-complex, along with thymoquinone — a biologically active compound known for its powerful antioxidant, anti-inflammatory, and immune-modulating effects.

Key benefits of black seed oil are enhances immune cell activity (especially T-killer cells), helps protect against viruses and bacteria, supports the thymus gland (key organ of the immune system), contains nigellone, a unique compound that boosts the body’s resistance to oxidative stress. It stimulates natural production of interferon, a key immune response protein

Recent studies show that consuming 2 teaspoons of black seed oil daily for 4 weeks can increase immune cell levels by up to 72%.

In the United States, Nigella sativa-based products are officially recognized as effective for immune system support.
