Supplements, or dietary supplements, are products that aim to supplement the daily diet and can include vitamins, minerals, herbs, amino acids and enzymes. They are available in various forms such as tablets, capsules, powders, vials and energy bars. The time it takes to notice the effects of supplements can vary greatly depending on the type of supplement, the dosage, the individual's metabolic rate and the individual's diet and lifestyle. In this article, we will take a closer look at the duration of effects of different groups of supplements. Dietary supplements are basically intended for preventative health maintenance.
Multivitamins
Multivitamin supplements contain a combination of different vitamins and minerals. They are designed to compensate for possible nutritional deficiencies in the diet. The effects of multivitamins tend to occur slowly and are therefore designed to be long-term. It can take several weeks to months before improvements in general health, such as a strengthened immune system or improved energy levels, become noticeable.
Short-term phase (1-2 weeks): Barely noticeable changes as the body begins to absorb the additional nutrients.
Medium-term phase (1-3 months): Improvements in energy, mood, and possibly better sleep may occur.
Long-term phase (3-6 months and longer): Improvement of vitamin deficiencies, strengthening of the immune system, improved skin quality and other health benefits become visible.
Omega-3 fatty acids
Omega-3 fatty acids, often available in the form of fish oil and algae oil , support heart health, promote cognitive functions and can have anti-inflammatory effects. The first effects, such as a reduction in inflammatory markers in the blood, can be seen within a few weeks. However, visible improvements in areas such as heart health or cognitive function can take longer - often several months.
Short-term phase (2-4 weeks): Reduction of inflammatory markers in the blood can be measurable.
Medium-term phase (2-3 months): Improvements in heart health and cognitive function can begin.
Long-term phase (6 months and longer): Significant benefits for cardiovascular health and brain function, as well as potential reduction in depression symptoms.
Protein supplements
Protein supplements such as whey or plant-based protein (pea, rice, soy, etc.) are particularly popular with athletes and people who want to build or maintain muscle. The speed at which effects become visible depends largely on the intensity of training and the quality of nutrition. Improvements in muscle mass and strength can be noticeable after just a few weeks of regular training and adequate protein intake.
Short-term phase (within weeks): Increase muscle repair and growth after training.
Medium-term phase (1-2 months): Visible improvements in muscle mass and strength while maintaining physical activity.
Long-term phase (3-6 months and longer): optimization of body composition and further muscle building.
Herbal and plant extracts
Herbal and plant extracts are a diverse group of dietary supplements derived from various parts of plants, including leaves, roots, berries, and seeds. They often contain a wide range of bioactive compounds (phytochemicals) that can provide various health benefits. The phases of action of herbal and plant extracts can vary greatly, depending on the specific type of extract and the health benefits it provides. Here we look at some general time frames for how these supplements work:
Short-term phase (1-2 weeks)
Instant relief: Some herbs like peppermint (for indigestion) or chamomile (for better sleep) can work relatively quickly and provide mild relief within days.
Initial improvements: Adaptogenic herbs such as ginseng or Rhodiola rosea can begin to modulate stress responses and energy levels.
Medium-term phase (1-3 months)
Increased effectiveness: Many plant extracts require time to accumulate in the body and develop their full effect. During this phase, improvements in cognitive function, well-being and physical performance can be seen.
Improved stress tolerance and immune function: Adaptogenic and immunomodulatory herbs such as echinacea or astragalus can strengthen the immune system and increase resilience to stress.
Long-term phase (3-6 months and longer)
Chronic conditions and preventative health: For long-term benefits, especially in preventing or supporting chronic health conditions, herbal and plant extracts can be taken on an ongoing basis. For example, turmeric, green tea extract (for antioxidant benefits), ginseng, ginger, and black pepper can help reduce the risk of certain diseases and promote overall health.
Improvement in quality of life: Long-term use can also lead to significant improvements in quality of life, including better joint health, improved cognitive function, and a healthier cardiovascular system (as seen with hawthorn intake).
Probiotic
Probiotics, which contain living microorganisms and are used to support intestinal health, can work relatively quickly. Positive changes in digestive problems or the immune system can be observed after just a few days or weeks. However, long-term use is necessary for lasting effects on the intestinal flora.
Short-term phase (1-2 weeks): Improvements in digestive problems may be noticeable.
Medium-term phase (1-3 months): Improvement in mood and food allergies (such as lactose intolerance), stabilization of intestinal flora and further improvements in digestive health.
Long-term phase (3-6 months and longer): Sustained positive effects on the immune system, skin quality, vaginal health, cognitive function and general gut health.
Antioxidants
Antioxidants protect the body from free radical damage and support the immune system. Time to effects can vary; mild improvements such as a strengthened immune system may be noticeable within a few weeks, while long-term benefits such as reduced oxidative damage and improved skin health may take longer.
Short-term phase (2-4 weeks): Potential improvement of the immune system and reduction of fatigue.
Medium-term phase (1-3 months): Protection against oxidative stress and support of skin health.
Long-term phase (3-6 months and longer): Long-term prevention of chronic diseases and aging processes.
Individual differences
The duration of action of dietary supplements varies depending on individual circumstances. These include genetic factors, health status, eating habits, existing nutrient deficiencies and lifestyle. The body's different storage capacity for vitamins is particularly relevant. For example, overweight people can store more of the fat-soluble vitamin D due to their higher fat content. These individual variables make the duration of action of supplements very personal and emphasize the need for an individually adjusted dosage for optimal results.
In summary , the time to action of supplements varies. Multivitamins show long-term improvements, while omega-3 fatty acids and protein supplements may work faster. Herbal and plant extracts, probiotics and antioxidants have different time periods of action, from immediate relief to long-term health benefits.
