ACTIVE INGREDIENTS

Important Vitamins for Bones, Immune System & Cell Protection

Five vitamins as the foundation of the mixture:

Vitamin A (800 μg, 100% NRV) as a retinol equivalent from β-carotene (plant-based) – contributes to the normal function of the immune system and the maintenance of normal skin.

Vitamin D3 (30 μg, 600% NRV) as cholecalciferol (plant-based) – contributes to the maintenance of normal bones, normal muscle function, and the normal function of the immune system.

Vitamin E (25 mg, 208% NRV) as natural d-alpha-tocopherol (plant-based) – contributes to the protection of cells from oxidative stress.

Vitamin K2 (70 μg, 93% NRV) as menaquinone-7 – contributes to the maintenance of normal bones and normal blood coagulation.

Vitamin C (300 mg, 375% NRV) as L-ascorbic acid (fermentatively produced) – contributes to the reduction of tiredness and fatigue, normal psychological function, and the normal function of the immune system, and increases iron absorption.

Vitamin B complex (B1, B2, niacin, B6, B9, B12, biotin, B5)

Eight B vitamins in highly bioavailable forms:

Vitamin B1 (3.3 mg, 300% NRV) as thiamine hydrochloride (fermentatively produced) – contributes to the normal function of the nervous system and to normal psychological function.

Vitamin B2 (4.2 mg, 300% NRV) as riboflavin (fermentatively produced) – helps reduce tiredness and fatigue.

Niacin / B3 (16 mg, 100% NRV) as nicotinamide (fermentatively produced) – contributes to the normal function of the nervous system and to normal psychological function.

Vitamin B6 (10.4 mg, 746% NRV) as pyridoxal-5-phosphate, active form (fermentatively produced) – contributes to the normal function of the nervous system and to normal psychological function and helps reduce tiredness and fatigue.

Vitamin B9 (272 μg, 136% NRV) as bioactive calcium L-5-methylfolate (fermentatively produced) – contributes to normal psychological function and helps reduce tiredness and fatigue.

Vitamin B12 (50 μg, 2000% NRV) as methylcobalamin (fermentatively produced) – contributes to the normal function of the nervous system and to normal psychological function and helps reduce tiredness and fatigue.

Biotin (50 μg, 100% NRV) as D-biotin (fermentatively produced) – contributes to the normal function of the nervous system and to normal psychological function.

Vitamin B5 (18 mg, 300% NRV) as calcium D-pantothenate (fermentatively produced) – contributes to normal mental performance and helps reduce tiredness and fatigue.

Minerals (Calcium, Magnesium)

Two minerals in proven compound forms:

Calcium (500 mg, 62% NRV) from calcium lactate and calcium carbonate (mineral source) – contributes to the maintenance of normal bones and to normal muscle function.

Magnesium (342 mg, 91% NRV) from magnesium carbonate and trimagnesium dicitrate (mineral source) – contributes to the reduction of tiredness and fatigue, to the normal function of the nervous system and to normal psychological function.

Trace elements for cognitive function

Four essential trace elements in proven compound forms:

Iron (10 mg, 71% NRV) as iron bisglycinate (mineral source) – contributes to normal cognitive function and helps reduce tiredness and fatigue.

Zinc (5.3 mg, 53% NRV) as zinc citrate (mineral source) – contributes to normal cognitive function and the normal function of the immune system.

Copper (880 μg, 88% NRV) as copper sulfate (mineral source) – contributes to the normal function of the nervous system and to the protection of cells from oxidative stress.

Manganese (2.2 mg, 110% NRV) as manganese sulfate (mineral source) – contributes to the protection of cells from oxidative stress and to normal energy metabolism.

Other trace elements (selenium, chromium, molybdenum, iodine, silicon)

Five trace elements that round off the composition:

Selenium (40 μg, 73% NRV) as sodium selenite (mineral source) – contributes to the normal function of the immune system and to the protection of cells from oxidative stress.

Chromium (22 μg, 55% NRV) as chromium(III) chloride (mineral source) – contributes to the maintenance of normal blood glucose levels.

Molybdenum (22 μg, 44% NRV) as sodium molybdate (mineral source) – contributes to the normal metabolism of sulfur-containing amino acids.

Iodine (22 μg, 15% NRV) as potassium iodide (mineral source) – contributes to normal cognitive function.

Silicon (61.5 mg) as silicon dioxide – complementary trace element of the composition.

High-quality amino acids (taurine, threonine)

Two amino acids in free, directly usable form:

Taurine (250 mg) – endogenous, sulfur-containing amino acid compound found, among other places, in muscle and nerve tissue.

L-threonine (800 mg) (produced by fermentation) – essential amino acid and building block of endogenous proteins.

Our approach

Why isn't a single active ingredient enough?

Most dietary supplements fail not because of their composition, but due to two hurdles beforehand: Firstly, a single isolated active ingredient is not enough — your body can only make optimal use of nutrients when your reserves are replenished holistically, rather than just selectively supplemented.

Secondly, even the finest formulation is wasted if it never reaches the body — a large proportion of commercially available preparations are already broken down in the stomach.

That is why we rely on holistic formulations that take your entire needs into account so that your reserves can truly be replenished — supported by a release technology that ensures everything inside is actually absorbed.

Technology

What makes POWERLIFE® so special?

Conventional capsules and tablets are usually attacked by stomach acid before they can take effect. Our Biomatrix technology instead delivers the nutrients intact to the small intestine — the primary site of nutrient absorption — and releases them there over a delayed period of 6 to 8 hours, rather than all at once.

This is particularly crucial for water-soluble vitamins: conventional preparations are usually released quickly and just as quickly excreted before your body can use them. POWERLIFE® micronutrients, on the other hand, are available to your body steadily over several hours — similar to natural absorption from fresh fruit and vegetables.

FAQs

How and when do I take Schulstark?

You have three options: take the 1.5 scoops (10.3 g) directly and drink a glass of water afterwards, stir them into 100–250 ml of water or juice, or add them to yogurt or quark. Consume them quickly. It is best to take them shortly before, during, or after a meal, not on an empty stomach. Do not heat or chew.

Does it contain a lot of caffeine?

What is the difference between school-strong and wide awake?

hellwach contains caffeine (180 mg) and is designed for situations that require alertness and concentration. schulstark is caffeine-free and focuses on nutrients for cognitive function, mental performance, and the nervous system. We are happy to discuss which blend or combination is right for you in the free consultation.

How soon will I notice a change?

This varies from person to person. Every body reacts differently, which is why we recommend taking Schulstark regularly over an extended period. One pack (30 days) will allow you to monitor how your body reacts.
