• Pre-meal dietary supplement can help overcome fat and sugar problems, study suggests - Science Daily, 5/23/11 - "naringenin, the molecule responsible for the bitter taste in grapefruits, could potentially be used in the treatment of diabetes, arteriosclerosis and hyper-metabolism ... a nano-complex of naringenin within a ring of sugar called cyclodextrin. This complex increased the absorption of naringenin by 11 times ... a single dose of this complex, taken just before a high fat and high sugar meal given to rats, was able to reduce the generation of VLDL (bad cholesterol) by 42%, and increase insulin sensitivity by 64%" - See naringenin products at iHerb.  Also, if you do an iHerb search of cyclodextrin, it is listed in several products but not as an active ingredient.

• Skin photoprotective and antiageing effects of a combination of rosemary (Rosmarinus officinalis) and grapefruit (Citrus paradisi) polyphenols - Food Nutr Res. 2016 Jul 1;60:31871 - "We investigated the efficacy of a combination of rosemary (R. officinalis) and grapefruit (C. paradisi) in decreasing the individual susceptibility to UVR exposure (redness and lipoperoxides) and in improving skin wrinkledness and elasticity ... Treated subjects showed a decrease of the UVB- and UVA-induced skin alterations (decreased skin redness and lipoperoxides) and an improvement of skin wrinkledness and elasticity. No differences were found between the 100 and 250 mg extracts doses, indicating a plateau effect starting from 100 mg extracts dose. Some of the positive effects were noted as short as 2 weeks of product consumption ... The long-term oral intake of Nutroxsun™ can be considered to be a complementary nutrition strategy to avoid the negative effects of sun exposure" - [Nutra USA] - See Nutroxsun™ at Amazon.com.
• Grapefruit juice and liquorice increase cortisol availability in patients with Addison's disease - Eur J Endocrinol. 2011 Sep 6 - "Compared to the ordinary treatment, the median AUC for serum cortisol increased with liquorice (53783 vs. 50882, p<0.05) and GFJ (60661 vs. 50882, p<0.05). Cortisol levels in serum were also elevated 2.6h after tablet ingestion (liquorice 223 vs. 186 nmol/L, p<0.05; GFJ 337 vs. 186 nmol/L, p<0.01). Liquorice increased the median urinary cortisol/cortisone-ratio (0.43 vs 0.21, p<0.00001), whereas GFJ increased the (aTHF+THF)/THE-ratio (0.55 vs 0.43, p<0.05)" - Note:  From my readings, most have too much cortisol already.  I've read where licorice increases it.  Licorice and grapefruit juice sounds like an unlikely combination but people might want to be aware of it.
