Blue-green algae contain antioxidants like phycocyanin and beta-carotene, which may help protect cells from oxidative stress and reduce inflammation. Methylene blue has been shown to possess antioxidant and anti-inflammatory properties, which could help protect cells from damage and reduce inflammation in various systems of the body.

Blue-green algae contain compounds that might support brain health, including omega-3 fatty acids and phycocyanin. These compounds could potentially contribute to cognitive function and mood regulation. Some research indicates that methylene blue might have antidepressant effects by influencing neurotransmitter systems, particularly those related to serotonin and dopamine

Methylene blue is thought to improve mitochondrial function, which is crucial for energy production in cells. It might enhance the efficiency of cellular respiration, potentially leading to improved energy levels.

.Some studies suggest that certain compounds found in blue-green algae, such as polysaccharides and phycocyanin, might support the immune system by enhancing the activity of immune cells. Methylene blue has demonstrated antimicrobial activity against certain bacteria and parasites, making it potentially useful in certain infection scenarios.

Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and prevent hypocalcemia tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts. Without sufficient vitamin D, bones can become thin, brittle, or misshapen.
Vitamin D sufficiency prevents rickets in children and osteomalacia in adults. Together with calcium, Vitamin D also helps protect older adults from osteoporosis. Vitamin D has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation.

Some research indicates that methylene blue might have antidepressant effects by influencing neurotransmitter systems, particularly those related to serotonin and dopamine.
