Essential for immune regulation, many vegan athletes are deficient in D3. This specific source is derived from lichen, ensuring it is 100% plant-based while providing the active form needed to support T-cell function during periods of high physical stress.
Rich in anthocyanins, elderberry has been shown to reduce the duration and severity of upper respiratory infections. For athletes, it serves as a potent antioxidant that helps buffer oxidative stress generated during intense training sessions.
Critical for the development and communication of immune cells, zinc levels often drop after prolonged exercise. This highly bioavailable chelated form ensures optimal absorption to support barrier integrity and antimicrobial defense mechanisms.
These adaptogenic fungi contain beta-glucans that modulate the immune system, helping to prevent overtraining syndrome by balancing inflammatory responses. They offer neuroprotective benefits and support restful sleep, crucial for recovery.
As a water-soluble antioxidant, Vitamin C protects immune cells from free radical damage. Combining it with plant-derived bioflavonoids enhances absorption and synergistically supports collagen synthesis for joint health in heavy lifters.
An herbal supplement often used at the first sign of illness to shorten cold duration. Its active compounds can stimulate the activity of white blood cells, providing an additional layer of protection during peak training cycles.
Unlike fish oil, this source is derived from microalgae, making it suitable for vegans. EPA and DHA are powerful anti-inflammatories that help manage systemic inflammation caused by heavy training, reducing the risk of illness.
Aged garlic extract contains S-allyl cysteine, which has been linked to improved immune function and reduced severity of cold symptoms. It offers cardiovascular benefits while boosting the body's natural killer cell activity.
A potent flavonoid found in onions, apples, and capers, quercetin acts as an antiviral and anti-inflammatory agent. Supplementation can help stabilize mast cells and reduce exercise-induced immune suppression in endurance athletes.
Gut health is directly linked to immunity. Strains like Lactobacillus and Bifidobacterium support the gut barrier, preventing endotoxemia and systemic inflammation that can compromise immune function during high-volume training periods.
This functional mushroom enhances ATP production and oxygen utilization. By supporting cellular energy metabolism, it helps athletes maintain performance while reducing the physiological stress that typically leads to immune suppression.
The primary active compound in turmeric, curcumin is a powerful anti-inflammatory. When paired with black pepper extract for bioavailability, it helps manage post-exercise inflammation and supports overall immune resilience.
While traditional colostrum is bovine, emerging research explores plant-derived alternatives or immunoglobulin-focused plant compounds. Note: Most colostrum is not vegan, so focus on immune-supporting plant immunoglobulins instead.
Rich in epigallocatechin gallate, this extract boosts immune function and aids in fat oxidation. It provides a mild cognitive boost without the jitteriness of high caffeine, supporting mental recovery alongside physical healing.
A specialized form of zinc that supports gut lining integrity. Since a large portion of the immune system resides in the gut, maintaining mucosal health is critical for preventing pathogens from entering the bloodstream.
B vitamins are crucial for energy metabolism and nervous system health. Methylated forms ensure proper absorption for those with MTHFR gene variants, supporting the body's ability to manage stress and repair tissues efficiently.
A cornerstone of Traditional Chinese Medicine used to tonify the immune system. It helps prevent recurrent respiratory infections and improves the body's resistance to external pathogens during times of physical fatigue.
Essential for over 300 enzymatic reactions, magnesium supports muscle relaxation and sleep quality. Adequate levels are vital for preventing the cortisol spikes that can suppress immune function in overtrained athletes.
An adaptogen that lowers cortisol levels and improves recovery time. By regulating the stress response, it indirectly supports immune health, allowing the body to allocate more energy to repair and defense mechanisms.
A trace mineral that acts as a cofactor for glutathione peroxidase, a key antioxidant enzyme. It helps protect cells from oxidative damage caused by intense exercise and supports thyroid function, which regulates metabolism.
