India, Oct. 6 -- Collagen is a popular supplement for glowing skin, healthy hair, and strong joints, but many see little benefit. Often, it's not the collagen that's at fault, but common mistakes, which can block its effects. As nutritionist Karishmma Chawla explains, collagen isn't a "magic pill". Here are common collagen mistakes you should avoid so that your collagen actually works: Using the wrong type: The source and type of collagen affect absorption and results. Bovine, marine, and porcine are the most common, with marine often easier to absorb due to smaller peptides. However, your choice should align with your dietary needs. Inconsistent use or poor timing Collagen only works with regular use. Skipping doses reduces impact. Skipping quality checks: Stick to trusted brands with third-party testing and certifications like NSF or SGS. Avoid those that don't share purity results. Expecting quick results: Visible changes take 8-12 weeks. Quitting too soon means missing the benefits. Track progress and commit for at least three months. Ignoring other nutrients: Your body needs vitamin C, zinc, and copper to use collagen effectively. Without them, results may stall. Eat a balanced diet with citrus fruits, bell peppers, nuts, and lean protein. A recent study published in the International Journal of Cosmetic Science confirmed that vitamin C plays a direct role in collagen production. Overlooking lifestyle factors: Smoking, excess sugar, sun exposure, stress, and poor sleep can all block collagen's effects. Karishmma notes that lifestyle is just as important as supplementation. Overlooking side effects: Most people tolerate collagen well, but some may face bloating, nausea, or allergies, especially to fish, shellfish, or beef-derived collagen. Always check labels and consult a doctor if symptoms persist. For more such stories, visit healthshots.com...
