Vitamin D3 is one of the most important nutrients for supporting health — particularly in the Polish climate, where sun exposure is insufficient for most of the year. In the Vitaler’s Vitamin D3 range, you’ll find supplements in various dosages and forms: capsules, tablets, drops and complexes with calcium and vitamin K2 MK-7.

The role of vitamin D3 in the body

Vitamin D3 contributes to the normal functioning of the immune system and the maintenance of normal bones and muscles. It aids the absorption of calcium and phosphorus from the digestive tract, which is particularly important for bone health. It also plays a part in cell division. It is estimated that the majority of Polish adults are deficient in vitamin D3 — particularly between September and May, when vitamin D synthesis in the skin is virtually non-existent.

Dosage — how to choose the right strength

Vitaler’s range includes doses from 1,000 IU (in combination with calcium) through 2,000 IU, 4,000 IU, right up to high doses of 8,000 IU and 16,000 IU. The 4,000 IU dose is the most commonly chosen option by adults for preventative supplementation during the autumn and winter months. Higher doses are intended for people with a confirmed deficiency or a medical indication — we recommend consulting a doctor before taking them. If you’re looking for comprehensive support for your skeletal system, it’s worth trying combinations of D3 with vitamin K2 MK-7 or with calcium — you’ll find them in the Vitaler’s minerals category.

Forms of administration — capsules, tablets, drops

The range includes three forms of administration. Capsules and tablets are a convenient option for daily supplementation — they offer easy dosing and a precise amount of the active ingredient in each serving. Drops are ideal wherever dosage flexibility is required, e.g. for people who have difficulty swallowing. Norwegian cod liver oil with vitamin D3 forms a separate category, available in the Omega acids — a natural, liquid supplement combining D3 with EPA and DHA.

Purity of ingredients — the Vitaler’s standard

All Vitaler’s vitamin D3 supplements are produced without artificial colourings, preservatives or unnecessary fillers. Packaged in elegant glass jars with a transparent list of ingredients on the label — exactly what you’d expect from a brand you trust. You’ll find the full range of vitamins to complement your D3 supplementation in the Vitaler’s vitamins category.
