5 Winter Deficiencies Every Woman Should Know About

The days are shorter, the sun is low, and you often eat heavier meals — that's part of winter.
But at the same time, this means your body consumes more and produces less.
From an orthomolecular perspective, the absorption of vitamins and minerals decreases in winter, while stress, cold, and less exercise actually increase their consumption.

That's why many women between November and March suffer from vague complaints: fatigue, dry skin, increased hair loss, a dip in their mood, or poorer sleep.

Yet, these signals are often ignored, while they convey something important:

“Your body is not out of balance; it is undernourished at a cellular level.”

1. Vitamin D – sunshine in a capsule

Without sunlight, your skin produces hardly any vitamin D.
And although vitamin D is officially called a vitamin, it actually functions as a hormone that regulates hundreds of processes: from your immune system to your mood.

You may notice a deficiency by:

• Fatigue, despondency

• Muscle weakness

• Susceptibility to colds

Orthomolecular advice:

• Supplement daily with vitamin D3 (cholecalciferol).

• Take it with a meal containing fats for optimal absorption.

At Optemuse, we use naturally sourced vitamin D3, so your body can directly utilize it, as if it were sunshine in a capsule.

Magnesium – the mineral of rest and recovery

Magnesium is involved in over 300 bodily processes, including energy formation, muscle relaxation, and stress regulation.
However, stress, coffee, alcohol, and sugar lead to faster excretion through the kidneys.

You may notice a deficiency by:

• Muscle tremors or stiff shoulders

• Poorer sleep

• Irritability or restlessness

Orthomolecular advice:

• Choose Magnesium Citrate, a well-absorbed form that is gentle on the intestines.

• Use it in the evening to relax and improve sleep quality.

At Optemuse, we combine magnesium with vitamin B6, as it promotes absorption into the cells.

Omega-3 fatty acids – nutrition for brain, skin, and hormones

Omega-3 fatty acids (EPA & DHA) are essential for cell membranes, brain function, and hormone balance.
They reduce inflammatory responses, support healthy skin, and contribute to a stable mood.

You may notice a deficiency by:

• Dry or flaky skin

• Poorer concentration

• Irritable mood

Orthomolecular advice:

• Consume 1000–2000 mg of EPA/DHA daily from fish oil or algae oil (plant-based alternative).

• Combine with antioxidants (vitamin E or C) to prevent fatty acid oxidation.

In winter, Omega-3 is as indispensable as a warm coat — it protects your cells from internal stress.

B vitamins – the engine of your energy metabolism

Your cells use B vitamins to convert food into energy.
Chronic stress or hormonal fluctuations increase the consumption of these vitamins.

You may notice a deficiency by:

• Fatigue, listlessness

• Sadness

• Poor concentration

Orthomolecular advice:

• Use a B-complex with active forms such as methylcobalamin (B12) and P-5-P (B6).

• Pay attention to combinations: B vitamins work synergistically and should be balanced.

Optemuse's Multi Support contains all B vitamins in biologically active form, ensuring they work immediately — without conversion loss.

Zinc – essential for skin, hair, and immunity

Zinc supports the production of collagen, hormones, and antibodies.
During winter, zinc status declines faster due to less meat, fish, and seeds in the diet.

You may notice a deficiency by:

• Slow wound healing

• Hair loss or brittle nails

• Reduced taste or smell

Orthomolecular advice:

• Choose zinc citrate, a well-absorbed form.

• Combine with vitamin C — together they boost immunity.

These deficiencies are not coincidental but a reflection of modern lifestyles.
By targeted supplementation, you support your body where nutrition falls short.
