Pros: Minimal ingredients; safe for preconception, pregnancy, postpartum, and beyond; non-GMOCons: Available only via subscriptionFor Irena Kutza, MS, RD, CDN, a clinical administrative dietitian at Montefiore Health System, Needed Prenatal Collagen Protein powder ticks all the right boxes: It’s third-party tested and made using grass-fed and pasture-raised bovine collagen. Plus, it’s a safe option for pregnancy, nursing, and even afterward—you don’t have to be pregnant to take it.

Spoiled Child E27 Extra Strength Liquid Collagen

Pros: Good flavor without an aftertaste; easy to absorbCons: Contains artificial sweetenersIf you’re looking for a little help with visible signs of aging, consider Spoiled Child’s liquid collagen. This formula boasts a higher dose of vitamin C than competitors (with 89% of your daily value), which is great news for the skin’s elasticity and firmness. “Vitamin C supports your skin’s natural collagen matrix by helping with the stabilization and cross-linking of collagen fibers,” Callins says, adding that this process is necessary for skin to look healthy and firm.

We also like that Spoiled Child’s liquid collagen is made with hydrolyzed collagen peptides, which is an easier form of collagen for the body to absorb. In addition, the liquid formula is super easy and tasty to take, reviewers note. You can add it to sparkling water, smoothies, yogurt, or oatmeal for a light mango or pineapple flavor and a collagen boost.

Thorne Collagen Plus

Pros: Third-party-tested; contains longevity-supporting ingredientsCons: Contains stevia (which may have an aftertaste)Collagen isn’t the primary type of protein that comes to mind when weight loss is the goal, but that doesn’t mean it can’t help. A 2023 study shows taking collagen may help support lean muscle retention during weight loss. Thorne is a very reputable supplement line, and their Collagen Plus delivers a clinically supportive dose of collagen peptides at 13g per serving, which is close to the dose in the referenced study (15g), Callins says. Plus, it contains nicotinamide riboside (NR), which has been shown to increase levels of nicotinamide adenine dinucleotide (NAD) in the body, helping support longevity and energy levels, 2023 research shows.
