Brown Seaweed Extract

Brown seaweed extract contains fucoxanthin, a carotenoid investigated for fat loss. C-GRADE for blood pressure (small improvement), CRP (small decrease). D-GRADE for appetite and blood glucose (no effect). Fucoxanthin accumulates in fat tissue and may induce thermogenesis via UCP1 upregulation without CNS stimulation. Effects require 5-16 weeks to manifest due to slow accumulation. Limited human data - most evidence from animal studies. Non-stimulant approach to metabolic support.

Saffron is a spice with antioxidant properties derived from the flowering plant Crocus sativus. When used as a supplement, saffron seems to be effective at reducing symptoms of depression and possibly anxiety.

Resveratrol

5 shared conditions Β· 318 outcomes

Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.

Fish Oil

5 shared conditions Β· 448 outcomes

Fish oil is a mix of mostly EPA and DHA derived from fatty fish. It reduces triglycerides, but does not seem to affect the rate of cardiovascular events. It appears to reduce the symptoms of depression and improve some painful, inflammatory conditions.

Curcumin

Curcumin is the primary bioactive substance in turmeric. It has anti-inflammatory properties and can alleviate symptoms of depression as well as improve pain and function in people with osteoarthritis.

Chromium

5 shared conditions Β· 300 outcomes

Chromium is a mineral that occurs naturally in the earth’s crust and is found in small amounts in a variety of foods. Chromium supplementation seems to enhance the effects of insulin in the body, leading to improvements in insulin sensitivity and blood sugar regulation in people with insulin resistance. Although chromium has historically been considered an essential nutrient for the human body, current evidence challenges this notion.

L-Carnitine

5 shared conditions Β· 558 outcomes

L-carnitine can relieve leg pain in people with peripheral artery disease (PAD) and treat some aspects of metabolic syndrome. Although it’s often also used for fat loss, its effectiveness for that is questionable.

Whey Protein

4 shared conditions Β· 197 outcomes

Whey protein is one of the two high-quality proteins derived from cow’s milk (casein being the other). Its high digestibility, quick absorption, and well-researched benefits for muscle gain and cardiometabolic health make it a popular protein supplement among athletes and older adults.

Vitamin E

4 shared conditions Β· 274 outcomes

Vitamin E is a fat-soluble antioxidant that protects cells from oxidative damage and is found in several common foods. Supplementing with extra vitamin E does not have broad health benefits, except in people with vitamin E deficiency, and long-term high-dose supplementation may cause harm.
