Review of C4 Healthlabs Organic Full Spectrum Hemp Extract CBD Oil

C4 Healthlabs Organic Full Spectrum Hemp Extract CBD Oil is sourced from organic and non-GMO hemp. The product comes in three CBD concentrations: 500mg, 1000mg, and 2000mg in a 30ml bottle.

 The product is also BPA- and cruelty-free. BPA is an industrial chemical used to make certain plastics in resin. 

According to some studies, BPA might pose certain health risks, such as infertility, hormone-dependent tumors, and polycystic ovary syndrome (PCOS)[1].

According to its product page, the Organic Full Spectrum Hemp Extract CBD Oil is best taken under the tongue for faster absorption. However, the product may also be mixed with food or drinks.

Review of C4 Healthlabs CBD Topical Lotion (THC-Free)

C4 Healthlabs also offers the CBD Topical Lotion (THC-Free) that is mint-flavored and comes with 1000mg of CBD. Peppermint and spearmint oils add the mint flavor.

Its product page states that the lotion is fast-absorbing and non-greasy, comparable to creams used in luxury spas.  It is rich in skin-soothing oils, such as jojoba seed oil, sunflower oil, and shea butter.

Conclusion

C4 Healthlabs is dedicated to helping customers explore CBD’s potential health benefits by producing CBD products that are safe, consistent, and reliable. Through its use of organic, non-GMO, and additives-free raw materials, the company helps promote general health and wellness to its customers.
