ADEK Optima

Made for your daily routine.

Vitamins A, D, E, and K are fat-soluble, so the formula uses a coconut-derived MCT oil capsule. It provides 2,000 IU of vitamin D3, vitamin K2 as menaquinone-7, vitamin A as retinyl palmitate, and natural vitamin E from sunflower oil, combining four nutrients in one product.

One capsule daily provides a simple routine, with 60 days of use per bottle. The vegetarian capsule suits those following a vegetarian diet, while oxygen-free packaging helps protect the ingredients until use.

Why do vitamins A, D, E, and K matter?

These vitamins have complementary nutritional roles. Vitamin A supports normal vision, skin, and immune function. Vitamin D supports bones, teeth, and muscles and the normal absorption of calcium and phosphorus. Vitamin K supports normal bones and blood clotting, while vitamin E helps protect cells from oxidative stress. The formula brings all four together in one daily capsule.

What research informs ADEK Optima?

Vitamin D research spans immune function, muscles, and bone health, including studies of daily 2,000 IU supplementation in adults. Vitamin D and K have complementary roles in calcium metabolism. Vitamin A supports immune function and normal mucous membranes, while vitamin E helps protect cells from oxidative stress. These established nutritional roles informed the combined formula; individual requirements still depend on diet and health circumstances.

FAQ / ADEK Optima

Good questions. Clear answers.

Talk to us ↗

Why combine vitamins A, D, E, and K?

These fat-soluble vitamins have complementary roles in immune function, bones, muscles, vision, blood clotting, and cellular protection. One formula brings them together without the need for several separate products.

Why use coconut-derived MCT oil?

Vitamins A, D, E, and K dissolve in fat, so an oil base suits these nutrients and brings them together in one capsule. Take the capsule with a meal or with 200 ml of water, as directed.

Does the vitamin A come from beta-carotene?

No. The formula uses retinyl palmitate, a preformed source of vitamin A. One capsule provides 800 µg of vitamin A, equal to 100% of the EU Nutrient Reference Value. Do not combine it with other high-dose vitamin A products without professional guidance.

Is ADEK Optima suitable for vegans and vegetarians?

The capsule is suitable for a vegetarian diet. We do not classify the product as vegan. If your diet excludes particular ingredients or sources, check the full ingredient list before purchase.

Who is ADEK Optima for?

The formula is designed for adults seeking a convenient combination of fat-soluble vitamins. It may appeal to women, men, and older adults looking to support normal immune function, bones, vision, and cellular protection in one daily routine.

How many days does a bottle provide?

Each bottle contains 60 capsules. At one capsule daily, it provides a 60-day supply.

Can I take ADEK Optima with medication or other supplements?

Before combining products, add up your vitamin A, D, E, and K intake from all sources. If you take medication, especially medication that affects blood clotting, or are pregnant or breastfeeding, consult your doctor or pharmacist first.
